medicines in development hiv/aids -...
TRANSCRIPT
Biopharmaceutical research companies are developing 73 medicines and vaccines, focusing on improved treatment regimens, more effective therapies and promising new preventative vaccines.
Although HIV/AIDS is one of the most devastating diseases affecting people around the world, the number of new infections has been steadily declining. In the United States, the AIDS-related death rate has fallen by 79 percent due to antiretroviral therapy.
Over the past 30 years, nearly 40 medicines have been approved to treat HIV/AIDS. Testing for the disease also has advanced dramatically, enabling earlier treatment. While these medicines have helped to prolong the lives of HIV-infected patients, making HIV a manageable chronic disease, opportunities for even greater progress remain.
For example, biopharmaceutical companies are intensifying their efforts to develop vac-cines that would help prevent HIV. Current estimates show that a 50 percent effective
vaccine given to only a third of the population could reduce new HIV infections by 24 percent over 15 years.
The medicines in the development pipeline include:
• A gene therapy that uses genetic material to remove disease-causing aspects of the virus.
• A transdermal vaccine that helps suppress vi-rus replication and destroys HIV-infected cells.
• A first-in-class medicine intended to prevent the HIV virus from breaking through the cell membrane.
Despite the incredible progress to date, the HIV/AIDS epidemic remains a complex prob-lem. America’s biopharmaceutical research companies are continuing their efforts to de-velop novel and more effective therapies, vac-cines to prevent the disease, and potentially a cure, so the millions of patients suffering today have hope for a better tomorrow.
Biopharmaceutical Researchers Are Testing More Than 70 Medicines and Vaccines For HIV Infection

Glossary
application submitted—An application for marketing has been submitted by the company to the Food and Drug Administration (FDA).
entry inhibitor—Unlike other HIV drugs that work after HIV has entered the human immune cell, entry inhibitors work outside the CD4 cell, blocking the virus from entering the cell. The process of HIV entry into a cell requires a series of steps in sequence involving several key proteins. Different entry inhibitors target separate proteins in the process. One type of entry inhibitor blocks the attachment of the HIV protein gp120 to CD4 cell receptors on the cell surface. Another inhibitor targets the binding of the virus to CCR5 or CXCR4 co-receptors involved in the virus entering the cell. And a third entry inhibitor interferes with the fusion of the HIV virus with T-cells at the cell membrane.
HIV infection—The presence of antibodies in the blood to the human immunodeficiency virus (the virus that causes AIDS). HIV-1 refers to the most common strain of the virus found in U.S. AIDS patients.
integrase inhibitor— A class of antiretroviral drugs designed to block the action of integrase, an enzyme that inserts the virus into the DNA of human cells. Since integration is a vital step
in the virus’ replication, blocking it can halt further spread of the virus.
pK enhancer—Pharmacokinetic (PK) en-hancer increases the effectiveness of pharma-ceutical treatment.
reverse transcriptase inhibitor (RtI)—When HIV infects a cell, reverse transcriptase changes the single-stranded RNA into a double-stranded viral DNA. The new viral DNA is then integrated into the human DNA cells, al-lowing reproduction of the virus. RTIs block this action and prevent completion of synthesis of the double-stranded viral DNA, preventing HIV from multiplying. RTIs are a class of antiretro-viral drugs.
NRtI—Nucleoside reverse transcriptase inhibitor.
NNRtI—Non-nucleoside reverse transcriptase inhibitor.
NtRtI—Nucleotide reverse transcriptase inhibitor.
phase 0—First-in-human trials conducted in accordance with FDA’s 2006 guidance on exploratory Investigational New Drug (IND) studies designed to speed up development of
promising drugs by establishing very early on whether the agent behaves in human subjects as was anticipated from preclinical studies.
phase I—Researchers test the drug in a small group of people, usually between 20 and 80 healthy adult volunteers, to evaluate its initial safety and tolerability profile, determine a safe dosage range, and identify potential side effects.
phase II—The drug is given to volunteer patients, usually between 100 and 300, to see if it is effective, identify an optimal dose, and to further evaluate its short-term safety.
phase III—The drug is given to a larger, more diverse patient population, often involving be-tween 1,000 and 3,000 patients (but sometime many more thousands), to generate statistically significant evidence to confirm its safety and effectiveness. They are the longest studies, and usually take place in multiple sites around the world.
pI—Protease inhibitors are a class of antiret-roviral drugs used to treat HIV infection. They prevent the HIV virus from replicating by inhib-iting the activity of proteases, such as HIV-1.

Selected Facts about HIV/AIDS
• In 2010, 2.7 million people became newly infected with HIV infection (including 390,000 children younger than age 15), down from 3.1 million in 2001. Although the annual number of people newly infected with HIV has dropped since its peak in the late 1990s, it is still occur-ring at an unacceptably high rate: between 2.5 million and 3 million people annually for the past five years, adding to the global number of people living with HIV that reached 34 million (including 3.4 million children younger than age 15) by the end of 2010.
• Globally, the annual number of people newly infected with HIV continues to decline, although there is stark regional variation. In sub-Saharan Africa, where most of the people newly infected with HIV live, an estimated 1.9 million people became infected in 2010. That was 16 percent fewer than the estimated 2.2 million people newly infected with HIV in 2001, and 27 percent fewer than the annual number of people newly infected between 1996 and 1998, when the incidence of HIV in sub-Saharan Africa peaked overall.
• Reductions in the number of people acquiring HIV infection, especially people ages 15–24 in the countries in sub-Saharan Africa that have a high burden of HIV, have been offset by increases in new infections in eastern europe and Central Asia. In those areas, where the primary mode of transmission of HIV is among people who inject drugs and their sexual networks, the number of people dying from AIDS-related causes increased 1,100 percent during the past decade: from an estimated 7,800 in 2001 to 89,500 in 2010.
• The annual number of people dying from AIDS-related causes worldwide is steadily decreasing from a peak of 2.2 million in 2005 to an estimated 1.8 million in 2010. That year, an estimated 250,000 children younger than age 15 died from AIDS-related causes, 20 percent fewer than in 2005. The number of people dying from AIDS-related causes began to decline in 2005–2006 in sub-Saharan Africa, South and Southeast Asia and the Caribbean and has continued subsequently.
• Introducing antiretroviral therapy has averted 2.5 million AIDS deaths in low- and middle-income countries globally since 1995. Sub-Saharan Africa accounts for the vast majority of the averted deaths: about 1.8 million.
• Providing antiretroviral prophylaxis to pregnant women living with HIV has prevented more than 350,000 children from acquiring HIV infection since 1995. Eighty-six percent of the children who avoided infection live in sub-Saharan Africa, the region with the highest prevalence of HIV infection among women of reproductive age.

Selected Facts about HIV/AIDS
HIV/AIDS in the United States1
• In 2010, an estimated 48,298 people were newly diagnosed with HIV infection in the 46 states and 5 U.S. dependent areas with confidential name-based HIV infection reporting. In the 46 states, 46,912 adults and adolescents were newly diagnosed with HIV infection, with 37,045 diag-noses in males and 9,868 diagnoses in females. Among children younger than age 13, there were an estimated 217 diagnoses of HIV infection.
• At the end of 2009, an estimated 1,148,200 people age 13 and older were living with HIV infection in the United States, including 207,600 people whose infections had not been diagnosed.
• In 2009, the estimated number of deaths of people with a diagnosis of HIV infection in the 46 states and 5 U.S. dependent areas with confidential name-based HIV infection reporting was 21,601. In the 46 states only, that included 21,007 adults and adolescents and 8 children younger than age 13.
• In 2010, the estimated number of people diagnosed with AIDS in the United States and 6 U.S. dependent areas was 33,630. In the 50 states and the District of Columbia, 24,749 AIDS diagnoses were among adult and adolescent males, 8,242 were among adult and adolescent females, and 23 diagnoses were among children younger than age 13.
• In 2009, the estimated number of deaths of people with an AIDS diagnosis in the United States and 6 U.S. dependent areas was 18,234. In the 50 states and the District of Columbia, that included 17,770 adults and adolescents and 4 children younger than age 13.
HIV/AIDS economic Impact
• The lifetime treatment cost of an HIV infection can be used as a conservative threshold value for the cost of averting one infection. Currently, the lifetime treatment cost of an HIV infection is estimated at $379,668 (in 2010 dollars); therefore, a prevention intervention is deemed cost-saving if its cost-effectiveness (CE) ratio is less than $379,668 per infection averted. The average annual cost of HIV care in the antiretroviral (ART) era is estimated to be $19,912 (in 2006 dollars; $23,000 in 2010 dollars). One study has estimated the medical savings from infections averted by United States prevention programs from 1991-2006 to be $129.9 billion with 361,878 HIV infections averted.1
• Nearly 30 years into the HIV epidemic, HIV continues to take a heavy toll in the United States. More than 1.1 million people are currently living with HIV, nearly 18,000 people with AIDS still die each year, and lifetime medical care for those who become infected with HIV each year is estimated to cost $20 billion.1
• Without intervention, a perinatal HIV transmission rate of 25 percent would result in 1,750 HIV-infected infants born annually in the United States with lifetime medical costs estimated to be $282 million. The cost of intervention (HIV counseling, testing, and zidovu-dine treatment) was estimated to be $67.6 million. That intervention would prevent 656 pediatric HIV infections, saving $105.6 million in medical care costs—a net cost-savings of $38.1 million annually.3

the U.S. system of new drug approvals is perhaps the most rigorous in the world.It takes 10-15 years, on average, for an experimental drug to travel from lab to U.S. patients, according to the Tufts Center for the Study of Drug Development. Only five in 5,000 compounds that enter preclinical testing make it to human testing. And only one of those five is approved for sale.On average, it costs a company $1.2 billion, including the cost of failures, to get one new medicine from the laboratory to U.S. patients, according to a 2007 study by the Tufts Center for the Study of Drug Development.Once a new compound has been identified in the laboratory, medicines are usually devel-oped as follows:preclinical testing. A pharmaceutical com-pany conducts laboratory and animal studies to show biological activity of the compound against the targeted disease, and the com-pound is evaluated for safety.Investigational New Drug Application (IND). After completing preclinical testing, a company files an IND with the U.S. Food and Drug Administration (FDA) to begin to test the drug
in people. The IND shows results of previous experiments; how, where and by whom the new studies will be conducted; the chemical structure of the compound; how it is thought to work in the body; any toxic effects found in the animal studies; and how the compound is manufactured. All clinical trials must be reviewed and approved by the Institutional Review Board (IRB) where the trials will be conducted. Progress reports on clinical trials must be submitted at least annually to FDA and the IRB.Clinical trials, phase I—Researchers test the drug in a small group of people, usually between 20 and 80 healthy adult volunteers, to evaluate its initial safety and tolerability profile, determine a safe dosage range, and identify potential side effects.Clinical trials, phase II—The drug is given to volunteer patients, usually between 100 and 300, to see if it iseffective, identify an optimal dose, and to further evaluate its short-term safety.Clinical trials, phase III—The drug is given to a larger, more diverse patient population, often involving between 1,000 and 3,000 patients (but sometime many more thousands), to generate
statistically significant evidence to confirm its safety and effectiveness. They are the longest studies, and usually take place in multiple sites around the world.New Drug Application (NDA)/Biologic License Application (BLA). Following the completion of all three phases of clinical trials, a company analyzes all of the data and files an NDA or BLA with FDA if the data successfully demonstrate both safety and effectiveness. The applications contain all of the scientific information that the company has gathered. Applications typically run 100,000 pages or more.Approval. Once FDA approves an NDA or BLA, the new medicine becomes available for physicians to prescribe. A company must continue to submit periodic reports to FDA, including any cases of adverse reactions and appropriate quality-control records. For some medicines, FDA requires additional trials (Phase IV) to evaluate long-term effects. Discovering and developing safe and effective new medicines is a long, difficult, and expensive process. PhRMA member companies invested an estimated $49.5 billion in research and development in 2011.
Developing a new medicine takes an average of 10-15 years; For every 5,000-10,000 compounds in the pipeline, only 1 is approved.
