Human Trial Results Show Excellent Safety Data, Positive Immune Responses From GeoVax's DNA/MVA AIDS Vaccines
Early results from GeoVax's preventative HIV/AIDS vaccine human trials:
-- Demonstrate a very acceptable safety profile in an ongoing 1/10th dose trial begun in April, 2006
-- Indicate that as low as 1/10th of a full dose of GeoVax's HIV/AIDS vaccine stimulates potentially protective anti-HIV-1 immune responses in the majority of vaccine recipients
-- Suggest an acceptable safety profile in an ongoing full dose trial begun Sept 2006
-- Suggest that a full dose of the vaccine will stimulate an even better immune response in recipients participating in the full dose trial; data is expected later in 2007
-- Support accelerated planning for a large Phase II human trial including more than 300 participants across North and South America and the Caribbean and with an earlier start date than originally anticipated
The 1/10th dose trial, begun April, 2006, is evaluating GeoVax's AIDS vaccines primarily for their safety and potential efficacy as a preventative vaccine administered to people prior to infection with the HIV-1 virus, thus preventing the development of AIDS. A positive human immune response to the vaccine is indicated by the presence of antibodies and T cells (white blood cells) that recognize and control viral infections.
"We are very encouraged by the positive immune responses in six human volunteers receiving only 1/10th of a dose of vaccine," said Dr. Harriet Robinson, GeoVax's Chief Scientific Advisor and developer of the AIDS vaccine. "This trial group consisted of 11 volunteers, with two individuals that received no vaccine as part of the blinded study. In this group, only 1/10th of a dose of GeoVax's DNA vaccine was administered at week 0 and at week 8 to prime the immune response. The immune response was then boosted by administration of 1/10th of a dose of GeoVax's MVA vaccine at week 16 and again at week 24."
The vaccine response was determined in tests conducted on human blood samples collected after vaccination. These assays were conducted at the Emory University Vaccine Center under the guidance of Dr. Harriet Robinson.
Based on the excellent safety demonstrated in the 1/10th dose vaccine trial, a full dose human trial started in September, 2006. Thus far, the trial has enrolled 36 volunteers. Thirty of the volunteers received the vaccine, while six control subjects received a placebo (no vaccine). The full dose of AIDS vaccine approximates the dose size that protected 22 of 23 (96%) of non- human primates for more than 3 1/2 years against development of AIDS. The immune response generated in the majority of volunteers receiving 1/10th dose of GeoVax's vaccines suggests that the vaccines, when administered at full dose, may elicit outstanding responses.
More information will be released on the full dose trial when available later in 2007. GeoVax's AIDS vaccines contain only part of the HIV-1 virus and cannot cause AIDS. These vaccines contain the three major genes of the HIV- 1/AIDS virus and mimic actual virus infections by producing non-infectious HIV-like particles in vaccinated individuals.
The human trials, utilizing GeoVax's AIDS vaccines, are being conducted by the HIV Vaccine Trials Network (HVTN), based in Seattle, Washington. The HVTN, which is funded and supported by the National Institutes of Health, is the largest worldwide clinical trials program devoted to the development and testing of HIV/AIDS vaccines. Preclinical work enabling development of the clinical evaluation of GeoVax's DNA and MVA vaccines was also funded and supported by the National Institutes of Health and the National Institute of Allergy and Infectious Diseases.

Reports, Programming Launched Ahead Of Annual National Black HIV/AIDS Awareness Day
- "HIV/AIDS Diagnoses Among Blacks -- Florida, 1999-2004," MMWR: According to an analysis from the Florida Department of Health released in the Feb. 2 issue of MMWR, new HIV cases among blacks residing in Florida has decreased by an average of more than 8% annually among men and more than 10% annually among women from 1999 to 2004, the AP/Gainesville Sun reports (Royse, AP/Gainesville Sun, 2/1). HIV incidence among blacks nationwide has decreased by an average of 5% annually since 2001, declining from 88.7 cases per 100,000 people in 2001 to 76.3 cases per 100,000 in 2004. However, blacks in 2004 were 8.4 times more likely than whites to be newly diagnosed with HIV (Kaiser Daily HIV/AIDS Report, 2/7/06). In Florida, HIV incidence among blacks dropped from 224 cases per 100,000 people in 1999 to 134 cases per 100,000 in 2004, the study found. According to the AP/Sun, the study's findings indicate that the decline is not because of a reduction in HIV testing among blacks, which increased during the study period. State health researchers also found that new cases of gonorrhea declined among blacks statewide during the same period by more than 7% annually, which indicates that the drop in both might be associated with a decrease in risky sexual behavior. Some health officials and advocates said that although they welcomed the study's findings, HIV among blacks is still high and the disparity between whites and blacks still persists (AP/Gainesville Sun, 2/1). According to the study, HIV incidence among whites in Florida was recorded at 18.8 cases per 100,000 population in 1999 and 18.4 cases per 100,000 population in 2004 (MMWR, 2/1).
- BET from Feb. 4 to Feb. 18 will launch three HIV/AIDS-themed programs aimed at addressing HIV/AIDS-related issues faced by black adolescents and young people -- including stigma, discrimination against men who have sex with men, HIV testing, substance abuse, and the impact of the disease on personal relationships and family. The broadcasts will begin at 12 p.m. ET/PT on Feb. 4 with "Reflections" -- the winning short film from the first Scenarios USA/Rap-It-Up National Story and Scriptwriting Contest -- with encore broadcasts on Feb. 7 at 11 p.m. and Feb. 18 at 12 p.m. BET also will air a 30-minute documentary on the making of the short film -- "Behind the Scenes: Reflections" -- on Feb. 4 at 12:30 p.m., as well as "Odicie" -- the winner of the third annual Rap-It-Up/Black AIDS Short Subject Film Competition -- on Feb. 18 at 12:30 p.m. In addition, BET News on Feb. 7 at 8 p.m. will air a 30-minute show that examines common misconceptions that many young people hold about the disease. BET since 1998 has partnered with the Kaiser Family Foundation on Rap-It-Up, a public education campaign to inform young people about sexual health issues, including HIV/AIDS (BET/Kaiser Family Foundation release, 1/24).

New Compound Shows Promise In Halting HIV Spread
A nucleic acid, 2-5AN6B inhibited HIV replication in white blood cells from a group of 18 HIV infected patients by up to 80 percent, regardless of the patients' treatment regimens.
"A cure for HIV infection remains an elusive goal despite the significant impact of current treatments because of the virus' ability to adapt to and resist those treatments, and bypass the immune system's natural defenses," said Robert J. Suhadolnik, Ph.D., prinicipal investigator and professor of biochemistry at Temple University School of Medicine. "This compound prompts the body to restore its natural antiviral defense systems against the invading virus."
Current drugs for HIV work by blocking one of the steps toward virus replication.
"This new anti-HIV compound works by a very different mechanism, and would appear to offer the promise of someday being combined with existing anti-viral therapies for a much more effective treatment. It is also very important that this compound is much less likely to be defeated by the ability of the virus to mutate, a problem often encountered with existing anti-viral drugs," said Thomas Rogers, Ph.D., co-author and professor of pharmacology at Temple.
This work builds on decades of research by the Temple team which was recently awarded a grant from the National Institutes of Health to continue pre-clinical studies on a larger scale. They'll be investigating the molecular mechanisms of 2-5AN6B as a potential weapon against HIV, and continue work on a new therapeutic approach involving gene therapy for the treatment of HIV infection.

Studies Examine HIV Dementia In Sub-Saharan Africa, CDC's HIV Prevention Budget
- "Frequency of and Risk Factors for HIV Dementia in an HIV Clinic in Sub-Saharan Africa," Neurology: Ned Sacktor, a neurologist at the Johns Hopkins School of Medicine, and colleagues conducted the study among 178 people in Kampala, Uganda, from September 2003 to January 2004, Xinhuanet reports. Seventy-eight of the participants were HIV-positive and 100 were HIV-negative (Xinhuanet, 1/30). The study found that 31% of participants in the HIV-positive group, or about 25 people, had HIV dementia, while none of the HIV-negative participants had the condition (Fox, Reuters South Africa, 1/29). Researchers characterized HIV dementia as memory, learning, behavioral and motor disabilities that interfere with daily activities and could lead to incapacitation. They diagnosed the dementia by examining participants' medical histories, as well as the results of a series of comprehensive neurological and neuropsychological tests and functional assessments, Xinhuanet reports (Xinhuanet, 1/30). "If the rate we saw in our study translates across sub-Saharan Africa, we're looking at more than eight million people in this region with HIV dementia," Sacktor said (Reuters South Africa, 1/29). According to researchers, HIV dementia can be treated and potentially reversed with the same antiretroviral drugs used to treat the virus, and treatment can sometimes restore normal cognitive function, Xinhuanet reports (Xinhuanet, 1/30).
- "HIV Incidence and CDC's HIV Prevention Budget: An Exploratory Correlational Analysis," American Journal of Preventive Medicine: David Holtgrave of Johns Hopkins University's Bloomberg School of Public Health and Jennifer Kates of the Kaiser Family Foundation examined the relationship between CDC's HIV prevention budget and HIV incidence in the U.S. from 1978 to 2006. The study found that from the beginning of the epidemic to 1985, when new HIV cases peaked in the U.S., HIV incidence predicted levels of investment. During this period, increased amounts of funding were allocated to HIV prevention programs as new HIV cases increased each year. From the mid-1980s, the level of investment predicted incidence, the study found. During this period, the U.S. continued to increase funding for HIV prevention programs, and the number of new cases decreased from 160,000 annually to about 40,000 annually, according to the study. In the early 1990s, as the level of investment leveled out, so did the number of new annual HIV cases, the study found. "Our analysis helps explain why the number of new HIV infections has remained at 40,000 per year for over 15 years," Holtgrave said, adding, "Investment levels have predicted HIV incidence since the mid-1980s. If we want to lower infections further in the U.S., these analyses suggest we should consider increasing our national investment" in HIV prevention programs. Holtgrave said that because the study is based on historical data, it is subject to methodological limitations (JHSPH release, 1/31).

India To Establish 'Safe Zones' To Reduce HIV Transmission Among Migrant Workers
Indian State To Require HIV Tests for Married Couples, Politicians
In related news, the Indian state Karnataka plans to pass legislation that would require HIV tests for couples planning to marry and for politicians entering the state Legislature, the Indo-Asian News Service/Daily India reports. Nearly 10% of HIV-positive people in India, or 500,000 people, live in Karnataka, and the state's HIV prevalence is 1.56%, according to the Karnataka State HIV/AIDS Society. According to the Karnataka Health Minister R. Ashok, the state will require the tests for politicians to encourage others to be tested for HIV. India's Ministry of Health and Family Welfare is opposed to mandatory testing, but Ashok said the issue is a state matter, according to Indo-Asian News Service/Daily India. "The state government is free to take new initiatives to control health problems like AIDS," Ashok said, adding, "We know the sensitivity of the issue, but the government needs to do something for the larger benefit of [the] people." The Indian state Andhra Pradesh is planning similar legislation, the Indo-Asian News Service/Daily India reports (Nanda, Indo-Asian News Service/Daily India, 1/31).

Phase III Trials Of Cellulose Sulfate Microbicide For HIV Prevention Closed
Simultaneously, Family Health International (FHI) has halted a second Phase III cellulose sulfate trial in Nigeria. Although the FHI trial did not detect an increased HIV risk associated with cellulose sulfate, the decision was made as a precautionary measure, given the preliminary results in the CONRAD trial. Cellulose sulfate (CS) was one of four microbicides currently in effectiveness trials for prevention of HIV and other sexually transmitted infections.
At this point, it is not clear why use of cellulose sulfate was associated with an increased risk of HIV infection in the CONRAD trial. The Independent Data Monitoring Committee (IDMC), an independent advisory group of experts overseeing the trial, will conduct a detailed review of the data to better understand the findings, and help determine any implications for other microbicide studies.
Dr. Lut Van Damme, principal investigator of the CONRAD trial, stated: "It was our hope that this product would have helped women in protecting themselves from HIV. While the findings are unexpected and disappointing, we will learn scientifically important information from this trial that will inform future HIV prevention research."
The microbicide, also known as Ushercell, is a cotton-based compound developed by Polydex Pharmaceuticals, based in Toronto, Canada. Prior to beginning the Phase III efficacy trials, there were 11 earlier safety and contraceptive trials on cellulose sulfate involving more than 500 participants in Africa, India, and the U.S. -- none of which identified safety concerns.
Recruitment for the CONRAD Phase III study began in July 2005. The study was conducted in areas of the world where HIV risk is greatest, and where infection occurs primarily through heterosexual intercourse. Half of the participating women were given cellulose sulfate, and half a placebo gel, in a double-blinded randomized trial design. All participants received intensive HIV prevention counseling at each monthly visit and all women were given high-quality condoms free of charge. Participants received regular testing and treatment for sexually transmitted infections. Pregnant women were not included in the study.
Participants were admitted into the study only after receiving detailed information about the purpose of the study and the possible health benefits and risks. During this process, their understanding of the study was assessed prior to their signing a consent form. Each trial site is linked to local organizations that provide care for women who become HIV-infected during the trial. As part of the trial preparation, CONRAD set aside funding for women who become HIV-positive during the trial to ensure adequate health care, including HIV antiretroviral treatment when needed.
Jeff Spieler, Chief of USAID's Research, Technology and Utilization Division, Office of Population and Reproductive Health said, "I am surprised and disappointed by these findings given the pre-clinical effectiveness and safety profile of CS, and its safety profile demonstrated in Phase I trials. I believe strongly that the field learns a great deal from every study, even those with disappointing results. The effort and resources that have been expended in terms of site and infrastructure development, training of clinical and laboratory staff, and community involvement activities will help move the field forward and pave the way to future studies." He continued, "I am also hopeful that one or more of the other microbicide candidates now in Phase III trials, and the next generation of products under development, will be shown to be safe and effective in helping to prevent HIV infection along with other behavioral interventions."
"Developing new tools to prevent HIV -- particularly for women -- is an urgent priority," said Dr. Henry Gabelnick, Executive Director of CONRAD. "We are committed to learning as much as possible from the trials of cellulose sulfate, and will use that knowledge to continue searching for compounds and collecting evidence to find a successful microbicide. Continued support for microbicide research is critical to our eventual success."
Cellulose Sulfate: Clinical Trial History (Safety and Efficacy)
Overview:
Prior to initiating two HIV prevention trials, CONRAD sponsored 11 clinical trials of cellulose sulfate (CS) involving 518 women and 48 men in the CS arms. These studies fall into four categories as follows:
* Safety studies in women -- 5
* Safety studies in men -- 2
* Other (safety of CS when used with a diaphragm and MRI imaging)- 2
* Contraceptive effectiveness studies - 2
Most of the trials were undertaken in the United States (7), one was done in Europe, and three in countries where the HIV prevention trials were expected to be carried out. The contraceptive effectiveness trials were carried out in the United States in mutually monogamous populations at low risk for STIs in which condom counseling was not required.
The safety studies in women and men varied in terms of control group (inactive sexual lubricant such as K-Y? Jelly or active spermicidal gel such as Conceptrol®), frequency of use (once, twice, or four times daily), duration of use (6-14 days), sexual activity (abstinent or active), and HIV status of participants (infected or uninfected). Endpoints included signs and symptoms of genital irritation, colposcopic findings, changes in vaginal microflora and, in some cases, vaginal inflammatory markers, and responses on acceptability questionnaires. The contraceptive studies used the prevention of pregnancy as the primary endpoint. The results of these studies have indicated that CS was as safe, acceptable, and effective as marketed spermicides and sexual lubricants.
The initial safety study was begun in 1999 and the contraceptive effectiveness trial was completed in July, 2006. The results of all eleven clinical studies to date have indicated that CS was as safe, acceptable, and effective as marketed spermicides and sexual lubricants.

African-American Women Who Have Received HIV Treatment Are Sought To Participate In GRACE Study
Today, women account for nearly one-third of new HIV diagnoses in the U.S., and rates of HIV infection are particularly high among women of color. African-American women, who represent only 13% of the U.S. female population, account for 64% of female AIDS cases.
"We expect GRACE will be an historic study because HIV treatment trials in treatment-experienced populations have traditionally included small numbers of women and people of color, especially in the earliest studies of new antiretroviral agents. We know that there are gender- and race-specific complications associated with HIV disease. However, we do not know a great deal about how gender and race impact the efficacy and side effects of HIV medications," said Debbie Hagins, M.D., Clinical Director of Outpatient Services, a Ryan White funded clinic in Savannah, GA, and an investigator in the GRACE study.
GRACE, a multi-center, open-label Phase IIIb trial, will compare gender differences in the efficacy, safety and tolerability of PREZISTA (darunavir) tablets administered with ritonavir and other antiretroviral agents over a 48-week treatment period. The study also will explore racial differences in treatment outcomes. Eligibility is open to men and women of all races.
PREZISTA, co-administered with 100 mg ritonavir (PREZISTA/r) and with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus (HIV) infection in antiretroviral treatment-experienced adult patients, such as those with HIV-1 strains resistant to more than one protease inhibitor. PREZISTA received accelerated approval based on the 24- week analysis of HIV viral load and CD4+ cell counts from the pooled analysis of the TMC114-C213 (POWER 1) and TMC114-C202 (POWER 2) studies. Longer-term data will be required before the FDA can consider traditional approval for PREZISTA (see the full indication and important safety information below).
"As an African-American woman living with HIV for more than 20 years, I am encouraged to see studies like GRACE that are designed to learn more about HIV treatment in treatment-experienced African-Americans and women in the U.S." said Rae Lewis-Thornton, a renowned AIDS activist and Emmy Award-winning journalist. "GRACE is an example of the steps that need to be taken to address the evolving HIV epidemic in the African-American community, and those who participate in GRACE will play a very important role in advancing the understanding of HIV treatment in women and people of color."
The GRACE study will include approximately 50 sites in the United States, Mexico and Canada, and will seek to enroll approximately 420 participants, 70 percent of whom will be women. Participants must be of 18 years or older, have a viral load of 1000 copies/mL or greater and have previous intolerance or failure to prior therapy consisting of a protease inhibitor and/or non- nucleoside reverse transcriptase inhibitor-based highly active antiretroviral treatment regimen of at least 12 weeks. All participants will receive PREZISTA/r (600/100mg twice a day) with an optimized background regimen chosen by the investigator and based on resistance testing and prior treatment history.
Indication
PREZISTA, co-administered with 100 mg ritonavir (PREZISTA/r) and with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus (HIV) infection in antiretroviral treatment-experienced adult patients, such as those with HIV-1 strains resistant to more than one protease inhibitor.
This indication is based on Week 24 analyses of plasma HIV RNA levels and CD4+ cell counts from two controlled trials of PREZISTA/rtv in combination with other antiretroviral drugs. Both studies were conducted in clinically advanced, treatment-experienced (NRTIs, NNRTIs, and PIs) adult patients with evidence of HIV-1 replication despite ongoing antiretroviral therapy.
The following points should be considered when initiating therapy with PREZISTA/rtv:
-- Treatment history and, when available, genotypic or phenotypic testing should guide the use of PREZISTA/rtv.
-- The use of other active agents with PREZISTA/rtv is associated with a greater likelihood of treatment response.
-- The risks and benefits of PREZISTA/rtv have not been established in treatment-naГЇve adult patients or pediatric patients.
Important Safety Information
PREZISTA does not cure HIV infection or AIDS, and does not prevent passing HIV to others.
PREZISTA is contraindicated in patients with known hypersensitivity to any of its ingredients.
Coadministration of PREZISTA/r is contraindicated with drugs that are highly dependent on CYP3A for clearance and have a narrow therapeutic index (e.g., astemizole, terfenadine, dihydroergotamine, ergonovine, ergotamine, methylergonovine, cisapride, pimozide, midazolam, or triazolam) and for which elevated plasma concentrations are associated with serious and/or life- threatening events. Coadministration is not recommended with carbamazepine, phenobarbital, phenytoin, rifampin, lopinavir/ritonavir, saquinavir, lovastatin, pravastatin, simvastatin, or products containing St. John's wort (Hypericum perforatum).
Caution should be used when prescribing agents such as sildenafil, vardenafil, tadalafil, or other substrates, inhibitors, or inducers of CYP3A in patients receiving PREZISTA/rtv. This list of potential drug interactions is not complete.
PREZISTA must be co-administered with 100 mg ritonavir and food to exert its therapeutic effect. Failure to correctly administer PREZISTA with ritonavir and food will result in reduced plasma concentration of darunavir that will be insufficient to achieve the desired antiviral effect. Please refer to ritonavir prescribing information for additional information on precautionary measures.
Severe skin rash, including erythema multiforme and Stevens-Johnson Syndrome, has been reported in subjects receiving PREZISTA during the clinical development program. In some cases, fever and elevations of transaminases have also been reported. In clinical trials (n=924), rash (all grades, regardless of causality) occurred in seven percent of subjects treated with PREZISTA; discontinuation due to rash was 0.3 percent. Rashes were generally mild-to-moderate, self-limiting and maculopapular. PREZISTA should be discontinued if severe rash develops.
PREZISTA should be used with caution in patients with known sulfonamide allergy.
New-onset or exacerbations of pre-existing diabetes mellitus and hyperglycemia, and increased bleeding in hemophiliacs have been reported in patients receiving protease inhibitors. A causal relationship between protease inhibitors and these events has not been established.
PREZISTA should be used with caution in patients with hepatic impairment. There are no data regarding the use of PREZISTA in patients with varying degrees of hepatic impairment; therefore, specific dosage recommendations cannot be made.
Redistribution and/or accumulation of body fat have been observed in patients receiving ARV therapy. The causal relationship, mechanism, and long- term consequences of these events have not been established.
Immune reconstitution syndrome has been reported in patients treated with ARV therapy.
The potential for HIV-cross-resistance among protease inhibitors has not been fully explored in PREZISTA/rtv treated patients.
PREZISTA should be used during pregnancy only if the potential benefit justifies the potential risk. There are no adequate and well-controlled studies in pregnant women. The effects of PREZISTA on pregnant women or their unborn babies are not known.
In the pooled analysis of POWER 1 and 2 studies, the most frequently reported drug-related adverse events of at least moderate to severe intensity in patients receiving PREZISTA/rtv-containing regimen were headache (3.8 percent), diarrhea (2.3 percent), abdominal pain (2.3 percent), constipation (2.3 percent), and vomiting (1.5 percent).
Please see full Prescribing Information for more details.

Preclinical Trial Results Of GeoVax's Vaccines Demonstrate Potential To Protect Against Development Of AIDS
In this trial, two monkeys were infected with the SIV AIDS virus and then placed on drug therapy. Thereafter, once early drug therapy had temporarily reduced virus levels, the monkeys were vaccinated with the SIV version of GeoVax's DNA/MVA vaccines. Six weeks after vaccination, drug treatment was discontinued. The SIV virus levels temporarily rose in the vaccinated individuals, but were later "controlled" (reduced to much lower levels) by immune responses raised by the vaccines.
The reduction of virus levels in the blood stream of these AIDS virus- infected non-human primates has continued for more than a year to date. Vaccination with the GeoVax DNA/MVA vaccines has curtailed the development of AIDS and its associated debilitating effects, resulting in healthy, asymptomatic individuals. The monkeys have gained weight and have not required any additional drug therapy.
"The results of this trial demonstrate the long-term promise of our vaccines in treating HIV-AIDS," said Don Hildebrand, CEO of GeoVax Labs. "Our preclinical trials, coupled with encouraging data from two ongoing human trials, help validate the science behind our vaccines and provide the impetus for accelerating the planning of Phase II human trials for our preventive vaccines."
The ability to vaccinate those already infected with the AIDS virus, thereby inhibiting the virus' progressive and debilitating effects, would allow individuals to fight off normal infections, live longer and maintain a more normal lifestyle. Such a vaccine, if approved for distribution, would be considerably more cost-effective and without the same side effects associated with current drug treatment programs.
The promising results from this trial have resulted in preliminary plans to conduct human therapeutic studies utilizing GeoVax's AIDS vaccines with the hope of extending the length and quality of life in people already infected with the AIDS virus.
These studies were conducted at Emory University and were supported by funding from the National Institutes of Health.

26 Years And HIV/AIDS Continues Unchecked
"Special events such as free HIV/AIDS testing, town hall meetings, candlelight vigils and faith-based programs are being held throughout the country. However, we must do more to stop the spread of this disease," said Albert W. Morris, M.D., president of the National Medical Association (NMA).
Despite 26 years of dealing with the disease, HIV/AIDS continues to be a critical health crisis for African Americans. The NMA strongly recommends that everyone be tested for HIV because there are a significant number of individuals who are unaware that they are infected and have never been diagnosed. "What is most disturbing regarding this epidemic is that we continue to diagnose African Americans at an advanced stage at their initial diagnosis. These individuals do not receive the benefits from early treatment which can prolong their lives," said, Dr. Virginia Caine, director, Marion County Health Department (Indiana) and NMA member.
According to the National Center for Health Statistics 2006 Report, HIV/AIDS is one of the top ten leading causes of death for African Americans. In the same year, African Americans accounted for more than half (54 percent) of the estimated new HIV infections in the United States. "It is clear that African Americans have been ravaged by this disease," says Los Angeles physician and director of the OASIS Clinic, Dr. Wilbert Jordan.
"The NMA supports the CDC recommendations and strongly recommends that physicians and other healthcare professionals offer routine HIV testing to their patients," concluded Dr. Morris. To support the NMA's call-to-action, Dr. Bennett Desdaier, president of the NMA affiliate, Aesculapian Medical Society in Indianapolis, Indiana; Dr. Wilbert Jordan, Los Angles; Dr. Robert Cater, Indianapolis; Dr. Mercy Obeime, Indianapolis; and Dr. Rodney Hood, San Diego are but a few of NMA physicians offering HIV testing from their offices to patients.
While NBHAAD is a nationwide effort, organizers have issued a Call to Action to cities, (e.g., Washington, DC; Atlanta, GA; Newark, NJ; Gary, IN; East St. Louis, IL; Baltimore, MD and others with high incidences of HIV and AIDS for African Americans) to host a "RE-Sound the Alarm" to ensure that Black communities realize that the epidemic continues to spread.

Few HIV-Positive Parents Make Formal Guardianship Arrangements For Their Children
RAND, a non-profit research organization, analyzed interviews with 222 unmarried parents with a total of 391 children from a nationally representative sample of HIV-infected adults. Of those parents:
* 12 percent had not identified a guardian for their children.
* 6 percent had identified a guardian but hadn't discussed their preference with the guardian.
* 53 percent said the guardian had agreed to be the guardian. * Only 28 percent had prepared legal documentation of their guardianship choice.
Studies have found that children who lose a parent to HIV/AIDS have higher rates of depression, risky sexual behaviors and other emotional and behavioral problems, making them vulnerable.
If parents have guardianship arrangements solidly in place - through a will or standby guardianship - they could help ease the trauma their children would suffer when losing a parent, because a guardianship plan can reduce the chances that children would be separated from their siblings or spend long periods of time in foster care.
"Ideally, we hope our findings will make physicians, especially pediatricians treating children who have HIV-positive parents, more aware of the guardianship issue, and more likely to talk to parents about the importance of making formal arrangements," said lead author Burton O. Cowgill. Cowgill is a researcher at the UCLA/RAND Center for Adolescent Health Promotion and a Ph.D candidate in the Department of Health Services in the School of Public Health at UCLA.
"All parents - not just parents with HIV or other, chronic illnesses - should consider a guardianship plan," Cowgill said. "By identifying who you want to be the guardian, you reduce the possibility of your children ending up with someone you don't want them to be with."
The RAND Health study, "Guardianship Planning Among HIV-Infected Parents in the United States," appears in the February issue of the journal Pediatrics. It was funded by the National Institute of Child Health and Human Development and the U.S. Centers for Disease Control and Prevention.
"I think parents often assume that if anything happens to them, then grandma, an uncle, or a close friend who spends a lot of time with their children will become the guardian, but the legal system doesn't always function the way parents assume it will," said Dr. Mark A. Schuster, senior author of the study and director of health promotion and disease prevention at RAND.
"Parents in two-parent families don't always consider that something could happen to both parents, and then the child can get caught in a tug-of-war among surviving family members," said Schuster, who is also professor of pediatrics and public health at UCLA's Mattel Children's Hospital.
One study of cancer patients who were single parents found that the children of 40 percent of them eventually became wards of people who the deceased parents would have opposed.
HIV-infected parents were most likely to have formalized guardianship arrangements if they were in poor health or were living with no other adults. The study also found that the age of the child had no impact on whether guardianship plans were more fully developed.
Among parents who identified a guardian, 36 percent listed a grandparent, followed by another relative (34 percent), the other biological parent (17 percent), a friend (7 percent), a spouse/partner who was not the biological parent (2 percent), an unrelated adoptive or foster parent (1 percent), and "other" (3 percent). Fathers were less likely than mothers to choose non-relatives.
The study used two waves of data from January 1996 to April 1997 and follow-up interviews from December 1996 through June 1997. The study drew on data collected for the HIV Cost and Services Utilization Study, a landmark study conducted by RAND.
Although the data are a decade old, Cowgill said the study is still relevant for several reasons, including the fact that it was drawn from a national probability sample of mothers and fathers, giving a more comprehensive picture. Past studies have been based on regional data, or were race- or gender-specific.
Also, the use of highly active antiretroviral therapy - which allows HIV-positive people to live longer with HIV - has become more common in the years since the data were collected. Since the study found that healthier parents were more likely to have no formal guardianship arrangements, it is likely that even fewer HIV-positive parents are making formal arrangements today.
Schuster said there were several reasons why HIV-positive parents might fail to make sure a legal guardianship was in place. Parents may have assumed that relatives or friends would step in and no one else would challenge the arrangements.
Parents also may fail to make formal guardianship arrangements because of distrust of the legal system, depression, fear that they can't afford a lawyer and not being aware of free or reduced fee legal services, or fear of being judged negatively due to their HIV-positive status. There's also the very human tendency to procrastinate and reluctance to face one's own mortality, Schuster said.
Other authors of the study are Marc N. Elliott, Megan K. Beckett, and Annie J. Zhou, all of RAND; Rosalie Corona, of Virginia Commonwealth University; and Michelle T. Parra, of the Los Angeles Department of Health Services.

Preclinical Results Of Geovax's AIDS Vaccines Demonstrate Potential To Protect Against Disease
In this trial, two monkeys were infected with the SIV AIDS virus and then placed on drug therapy. Thereafter, once early drug therapy had temporarily reduced virus levels, the monkeys were vaccinated with the SIV version of GeoVax's DNA/MVA vaccines. Six weeks after vaccination, drug treatment was discontinued. The SIV virus levels temporarily rose in the vaccinated individuals, but were later "controlled" (reduced to much lower levels) by immune responses raised by the vaccines.
The reduction of virus levels in the blood stream of these AIDS virus-infected non-human primates has continued for more than a year to date. Vaccination with the GeoVax DNA/MVA vaccines has curtailed the development of AIDS and its associated debilitating effects, resulting in healthy, asymptomatic individuals. The monkeys have gained weight and have not required any additional drug therapy.
"The results of this trial demonstrate the long-term promise of our vaccines in treating HIV-AIDS," said Don Hildebrand, CEO of GeoVax Labs. "Our preclinical trials, coupled with encouraging data from two ongoing human trials, help validate the science behind our vaccines and provide the impetus for accelerating the planning of Phase II human trials for our preventive vaccines."
The ability to vaccinate those already infected with the AIDS virus, thereby inhibiting the virus' progressive and debilitating effects, would allow individuals to fight off normal infections, live longer and maintain a more normal lifestyle. Such a vaccine, if approved for distribution, would be considerably more cost-effective and without the same side effects associated with current drug treatment programs.
The promising results from this trial have resulted in preliminary plans to conduct human therapeutic studies utilizing GeoVax's AIDS vaccines with the hope of extending the length and quality of life in people already infected with the AIDS virus.

AVAC Applauds Commencement Of First HIV Vaccine Efficacy Trial In Africa
The trial, which is known as Phambili (a Xhosa word meaning "moving forward") or HVTN 503, was launched today in South Africa by the South African AIDS Vaccine Initiative (SAAVI) and the HIV Vaccine Trials Network (HVTN) of the US National Institutes of Health.
"South Africa and the partner agencies in this study are demonstrating tremendous leadership. With the stakes as high as they are in the epidemic, accelerating large-scale efficacy trials in the countries and communities that need an HIV vaccine the most is the kind of forward-looking, strategic decision-making that the field needs and should embrace," said Mitchell Warren, Executive Director of the AIDS Vaccine Advocacy Coalition (AVAC).
The same vaccine candidate, which has been developed by Merck Research Laboratories, is currently being tested in another efficacy trial being conducted in various sites in North and South America, the Caribbean and Australia. The data from this study, known as the Step Study, are not yet known. Phambili has been initiated before the conclusion of the Step Study to help speed the progress of gathering additional important data in sub-Saharan Africa.
"The timing of the Phambili trial launch is a bold decision," said Warren. "There is an urgent need to identify new AIDS prevention strategies as quickly as possible; this sequence of trials will help move the field forward as quickly as possible. These two trials will combine to shed light on whether this vaccine candidate has the potential to be a truly global vaccine that can eventually be used in both developed and developing countries."
"As this trial moves forward, AVAC also hopes that this vaccine candidate will also be studied among adolescents. Adolescents are at great risk of HIV infection, and AVAC strongly supports the inclusion of adolescents in future trials so that we can get answers as quickly as possible for this priority population," Warren said.
"Finding an effective AIDS vaccine will not happen in one isolated sector or country, but from international collaborations between industry, government agencies, academia, and public-private partnerships. Phambili is an excellent example of putting public funds to good use to test a promising vaccine candidate," Warren said.
While there have been a significant number of small and mid-size safety studies conducted in sub-Saharan Africa, Phambili is the first study that is designed to provide information on whether or not a vaccine protects against HIV infection or helps to blunt HIV disease. Neither the Step Study nor the Phambili trial has been designed as the final study of this vaccine candidate; if there are indications of efficacy, additional studies will be conducted to confirm this preliminary finding.
