The meeting is open to the public, and there will be time for public testimony. Those wishing to speak should notify the contact person (below) in advance, by April 7 if possible. Perhaps more importantly, information can also be submitted in writing. The National Task Force "identifies any barriers and provides creative options for the rapid development and evaluation of treatments for HIV infections and its sequelae. It also advises on issues related to such barriers and provides options for the elimination of these barriers." The contact person for this meeting is Jean H. McKay, Office of AIDS and Special Health Issues (HF-12), Food and Drug Administration, 5600 Fishers Lane, Rockville, MD 20857, phone 301/443-0104, fax 301/443-4555. Comment This task force, meeting occasionally for two days in an auditorium, cannot automatically fix the problems of AIDS research -- any more than the election of a sympathetic U.S. president could automatically do so. What the National Task Force can do is to enable those who are working in the laboratories and clinics to explain their practical problems and their suggestions -- and hopefully get results. But principal investigators, research nurses, lab assistants, etc. will need to approach the task force and tell what they know. Often this is difficult, because of the politics of funding, or of the workplace; perhaps we need an organization called Speak Up to encourage people to give the task force the depth of information it needs. You can write to the National Task Force on AIDS Drug Development, c/o Jean McKay at the address above, at any time, before or after the upcoming meeting, and your information will be forwarded to the members. Incidentally, AIDS TREATMENT NEWS is always interested in such information; we read everything you send. You can write or call us at any time, anonymously if you want. ***** More on LTR Inhibitors: No Drug Resistance to a Tat Inhibitor by Charles Davidson The rapid development of drug resistance by HIV continues to be a major obstacle in finding better treatments. Resistance to AZT and similar drugs is well known; resistance to protease inhibitors, a new class of experimental drugs, is now also being found. A number of different strategies may help to deal with the problem, however. This article looks at what can be learned from one drug (Ro 24-7429, the Hoffmann-La Roche Tat inhibitor) to which HIV developed no resistance at all, in two years of laboratory studies which attempted to create such resistance.(1) We will also examine the class of drugs to which Ro 24-7429 belongs -- the LTR inhibitors. A look at how LTR inhibitors work suggests that they will need to be used in well- designed combinations in order to work most effectively. [Editor's note: Ro 24-7429 was tested alone, and rejected by Hoffmann-La Roche for further development, after it failed to reduce the level of p24 antigen in people in a small clinical trial; this data was presented at the Ninth International Conference on AIDS, in Berlin, in June 1993. Since that time, laboratory tests have shown that the drug works many times better when combined with pentoxifylline, a readily available prescription drug. Unfortunately the company had been trying to kill the project for several years, for business reasons, and had only kept it alive because of pressure from scientists, who understood the importance of this unique drug; AIDS TREATMENT NEWS has covered these events over the years. The negative result presented in Berlin provided the necessary excuse to stop development; and as a result of this drug's political history, there is virtually no chance that the company will run combination tests, which it could have done long ago. Ro 24-7429 remains important, not only in itself, but also for the doors it opens for developing better treatments. These possibilities urgently need more attention.

Pardee, Ph.D.," published in AIDS TREATMENT NEWS #192, February 4, 1994. Parts of this article are more technical than what usually appears in AIDS TREATMENT NEWS; for those who do not have a background in this area, we suggest reading the previous article first. If you do not already have a copy, you can obtain one by sending a self-addressed stamped envelope to: AIDS TREATMENT NEWS, P. O. Box 411256, San Francisco, CA 94141; be sure to mention "LTR" (or "issue #192") so that we will know which issue to send. HIV and Drug Resistance Nucleoside analog drugs (such as AZT or ddI) and protease inhibitors invite drug resistance because they are directed against viral proteins, which are highly prone to mutations (genetic changes) when HIV reproduces. Frequent mutations occur because reverse transcriptase (RT), the viral enzyme that produces copies of viral genes, is a thousand times more error- prone than the human enzyme that cells use when copying their own genes. Altered genes result in altered proteins. Therefore, while most essential human proteins are fairly accurately and consistently produced by human cells, viral proteins mutate at a rate hundreds of times faster. When mutations accumulate, the altered viral proteins are less able to bind to the drugs, so the drugs become less effective. Background: The HIV Life Cycle HIV is a retrovirus; and in retroviruses, the genetic information is in the form of RNA, not DNA as with most living things. After HIV infects a cell, the information in RNA is copied to DNA by reverse transcriptase (which is the enzyme inhibited by AZT). This DNA becomes incorporated into the DNA of the infected cell, whereupon it may either lie dormant or become active. If this "integrated" DNA is activated, more viral RNA is produced; some of it is "translated" into viral proteins, and some is encapsulated directly into new viral particles. While some viral proteins are used in constructing the viral coat, others regulate the production and processing of viral RNA from its (integrated) DNA "template". The most important of these regulatory proteins is Tat. Tat activates high levels of viral RNA production -- the first step in viral replication in an HIV-infected cell. About five percent of the viral DNA does not code for proteins at all, but instead acts as a binding site for a class of proteins known as activators. This portion of viral DNA is called the Long Terminal Repeat (or LTR); it functions as the "on" switch for the production of viral RNA. A number of proteins bind onto the LTR to activate it; the two most important are Tat (produced by HIV) and NF-kB (NF-kappa B, which is a normal and necessary human protein, but one which often becomes overactive in HIV disease and certain other chronic illnesses). Drugs which reduce activation of the virus by the LTR are called LTR inhibitors. Three potential treatments (topotecan, beta lapachone, and curcumin) have been found through a test to screen for LTR inhibitors (see AIDS TREATMENT NEWS issue #174, May 7, 1993). Antioxidants -- such as vitamins C and E, or curcumin (from the spice turmeric), or the amino acid N-acetyl cysteine.(2,3) (NAC), or the drug pentoxifylline -- are examples of one type of LTR inhibitor. These compounds work by preventing the binding of NF-kB to its DNA binding site, and those which have been tested have been observed in the laboratory to partially inhibit the production of HIV. Normal immune responses, inflammation, opportunistic infections and co-infection with other viruses all increase NF-kB binding and subsequent production of viral RNA. Individuals with HIV have impaired antioxidant defenses -- for example, they have abnormally low levels of cysteine. Conversely, a high cysteine level inside the cells (which provides for greater DNA-protective, antioxidant activity) is required for the DNA synthesis preceding T-cell division.(4) Therefore, not only does "oxidative stress" activate the LTR, it also inhibits the functioning of T-cells.(2) No Resistance with Tat Inhibitor Ro 24-7429 Unlike other activators, Tat binds onto recently formed RNA instead of onto DNA. Its binding site is a small region of the LTR known as TAR. There are only about 15 proteins coded for by the virus; therefore, HIV uses certain cellular (i.e., human) proteins to assist in its own replication. The Tat inhibitor, Ro 24-7429, however, prevents LTR activation by binding onto a cellular protein instead of onto Tat itself. Because this target is a human protein, not a viral one, resistance is unlikely to occur. Furthermore, when researchers flooded cells with the Tat protein in a 25-fold excess over that required for maximal activation, there was no decrease in the effectiveness of Ro 24- 7429. This suggests that it does not bind to Tat, since if it did, the large excess of Tat would have overwhelmed the drug.(1) Recent work by Alan Kingsman and colleagues at Oxford has now formally proven that Ro 24-7429 does not bind onto Tat at all, but rather to a cellular "loop binding protein." This protein, in turn, binds onto a small loop adjacent to the Tat binding site. Kingsman and colleagues suggest that the loop binding protein cooperates with Tat, and that Ro 24-7429 inhibits this interaction.(5) The hope from this research is that once the loop binding protein is physically isolated, its 3-dimensional structure will be determined. Knowing the structure could lead to the development of second-generation drugs with greater binding activity, smaller effective doses, and fewer side effects. In recently infected cell cultures exposed to very low doses of Ro 24-7429 alone, viral production is suppressed for a while, then it returns to higher levels. The lower the dose, the less the inhibition and the shorter the interval before viral production rebounds to higher levels. Low-dose monotherapy may result in only a partial suppression. This effect is probably not due to HIV resistance, but to increasing numbers of infected cells and accumulating amounts of viral proteins. Infected cells respond to these proteins by secreting inflammatory substances that increase NF-kB activity, thereby driving viral production higher. This result also suggests the importance of combination therapy, to prevent viral activation by Tat, while also preventing excessive activation by NF-kB. Synergy in LTR Activation and Inhibition The interrelationship of NF-kB and Tat in LTR activation (and hence viral production) is far more than additive. A modified LTR, in which the Tat activation pathway has been disabled, is activated by NF-kB alone to 15-fold above unstimulated (or basal) levels. An LTR without NF-kB (but with an intact Tat activation pathway) can be activated by Tat alone to 80-fold above basal levels. But HIV LTR with both NF-kB and Tat pathways intact can be activated 388- to 760-fold above basal levels by the combination of Tat and NF-kB (depending on the amount of Tat added).(6) And when both pathways are disabled, the virus cannot replicate at all. Such experiments indicate that NF-kB and Tat are required for replication and that they function synergistically. [Definition: "synergism" is defined by Stedman's Medical Dictionary as "coordinated or correlated action of two or more structures, agents, or physiologic processes so that the combined action is greater than that of each acting separately."] It is exactly this type of synergism that Debajit K. Biswas and colleagues (at Harvard University's Dana-Farber Cancer Institute) built upon when they analyzed the effects of an NF-kB inhibitor (pentoxifylline) combined with a Tat-inhibitor (Ro 24- 7429). They showed that when pentoxifylline and Ro 24-7429 were used together, instead of separately, only one-tenth as much of each compound was needed to produce the same LTR inhibition.(7) These results are important for two reasons. First, the synergism of Ro 24-7429 with other LTR inhibitors would allow the use of lower doses, and might therefore eliminate the side effects of the drugs. Second, lower doses of pentoxifylline would lead to less marked inhibition of NF-kB and leave unhindered certain important immune functions still dependent on NF-kB. More laboratory work is needed to determine the most effective and least toxic combination of LTR inhibitors. These would simultaneously reduce viral production and oxidative stress. Ro 24- 7429 should certainly be tested as a candidate for such a combination, as should the other recently developed Tat inhibitor from Allelix, Alx40-4C, which is presently in early clinical trials. LTR inhibitors with good toxicity profiles might sometimes show low efficacy as a monotherapy, but combinations would be expected to work much better. LTR combination therapy is definitely a here-and-now possibility that should go into clinical trials immediately. This new approach to treatment might become a valuable therapy in itself. And also, by reducing viral replication, it might help to delay the development of resistance to other classes of drugs, such as nucleoside analogs or protease inhibitors. References 1.

James A new clinical trial -- the first conducted jointly by the Federally- sponsored AIDS Clinical Trials Group and military institutions -- will study whether an advanced blood test can show the best time to switch from AZT alone to other treatments. This trial is seeking 300 volunteers, 150 from civilian and 150 from military sites, and will last for up to four years. This is the first time an AIDS clinical trial has used a virological test to change the treatment regimen at the first sign of viral resistance to the original treatment. All volunteers will begin this trial taking only AZT as the active drug. They will also take placebos for ddI, and for nevirapine, an experimental drug proposed for the "convergent combination" approach to triple-drug therapy. As the trial proceeds, their blood will be tested for the presence of a particular mutation of HIV, at "codon 215" (position 215 in the viral gene which codes for reverse transcriptase, the enzyme which is targeted by AZT, and also by ddI and nevirapine). At least five different mutations are known to cause AZT resistance; however, the one at position 215 is the most serious. When the mutation is detected (which can be at any time in the course of the trial, or never), the patient will be secretly assigned to one of three treatment groups: continuation of AZT, switch to AZT plus ddI, or switch to the triple combination of AZT plus ddI plus nevirapine. Neither the patient nor the research nurses, physicians, or study administrators will know if or when the switch occurs. Instead, one or more of the placebos will be changed to active drug, without their knowledge. This will make the pill-taking somewhat complex. All patients, throughout the trial, will take AZT every eight hours, ddI placebo (or real ddI) every 12 hours, and nevirapine placebo (or real nevirapine) once per day. And when they take the nevirapine, they will always take one pill from each of two different bottles. The reason for this is the protocol calls for starting nevirapine at half dose for the first eight weeks it is administered; the half dose is given by changing only one of the bottles from placebo to real drug. Eight weeks later, the other bottle also will be switched from placebo to drug. Once the mutation has been detected and randomization has occurred, the assigned treatment will be maintained throughout the trial, unless side effects or other problems force it to be discontinued. Note that this trial is designed to look for changes in blood measurements, not the development of clinical disease. It's main objective is "to validate that (the '215' mutation) precedes the increase in viral burden ...and decline in CD4 count which been observed in association with clinical failure" on AZT, and to see if adding the other drugs will prevent the increase in viral burden and decline in T-helper count. (The importance of the '215' mutation has been suggested by a small retrospective study of stored specimens. Seventeen patients with the mutation had a mean 50 percent decrease in T-helper count, during treatment of approximately three years; the other 21 patients had a mean increase of 11 percent. See Kozal MJ, Shafer RW, Winters MA, Katzenstein DA, and Merigan TC, Mutation in HIV Reverse Transcriptase and Decline in CD4 Lymphocyte Numbers in Long Term Zidovudine Recipients, Journal of Infectious Diseases 1993; pages 526-532.) The protocol chair for this study is Thomas C. Merigan, M. D., Stanford University Center for AIDS Research. The co-chair is Douglas L. Mayers, M. D., Walter Reed Army Institute of Research and Naval Medical Research Institute. Switch to Non-Blinded Therapies What about those who do poorly on the study, who may be randomly assigned to continue AZT after the resistance mutation has developed? The protocol calls for taking the volunteer off the study medication if (1) dose-limiting toxicity has developed, (2) an AIDS- defining condition develops (using the 1977 definition, as amended for this study), or (3) the patient's T- helper count has declined by more than 50 percent, as shown by two consecutive measurements at least 72 hours apart. If any of these occur, the patient's physician can begin any other treatment; the patient may continue to be enrolled in the trial for followup. However, the study will not pay for AZT or ddI once the patient is off the study medication; whether nevirapine (which is not commercially available) can be provided is being negotiated as this article goes to press. Also, the blind will not be broken until the study is finished and the data analyzed, so the volunteer who is taken off study medication will not be told whether it was AZT alone or something else that did not work for them. Eligibility, How to Enroll To be eligible for the study, volunteers must be asymptomatic, with T-helper count between 300 and 600. They must have had AZT for at least one month, uninterrupted, before being screened for the study, but must not have had more than two years of AZT. They must be at least 13 years old (at least 18 for the military sites). They must not have a history of pancreatitis, and must not currently be alcohol or drug abusers. Women are encouraged to enroll in this trial, but they will be excluded if they are pregnant, or intend to breast feed during the study. During the screening, they will be tested for the '215' mutation, and be excluded if it has already developed. There are a number of other medical and laboratory entry criteria. [One possible advantage of being screened for the study is finding out if one has the '215' mutation already; about half of those with T-helper count between 300 and 600 who have been tested do have it, and therefore they are not eligible to enroll in the study. They might want to start treatment with something other than AZT, for example, with ddI; however, there is no professional consensus yet about the clinical meaning of this mutation, which is why the study is being run. Unfortunately for some volunteers, the T-helper count is tested first; both samples are drawn on the same day, to avoid an extra visit, but if the T-helper test shows that the volunteer is ineligible, the virology test for the '215' mutation is not run. As far as we know, this test is not commercially available; it could become available, however, well before the trial ends.] The civilian trial sites are located in: Baltimore, Cleveland, Galveston, Los Angeles, Minneapolis, New York City, Philadelphia, Stanford (Palo Alto), Rochester, and Washington D. C. For the contact number to call for information at a site near you, call the AIDS Clinical Trials Information Service, 800/TRIALS-A. Ask for information about study ACTG 244. The military study slots are open to those who have an ID card which shows that they are eligible to receive care at a Department of Defense medical treatment facility. They can be a veteran, on active duty, or a dependent (age 18 or older). The DoD will fly them to a participating center, which will usually be either Wilfert Hall USAF Medical Center, San Antonio, Texas, or Walter Reed Army Medical Center, Washington, D. C., or National Naval Medical Center, Bethesda, Maryland. (Those not on active duty can choose whether to enroll at a military or a civilian site.) To enroll at a military site, call Douglas L. Mayers, M. D., at Walter Reed Army Institute of Research, 301/217- 9410, or Kenneth Wagner, D. O., at National Naval Medical Center, HIV Research Unit, 301/897-3290; they will refer you to a protocol nurse. Comment This study is expected to take four to six years to affect the standard of care -- two to four years of treatment time (depending on how many of the volunteers develop the '215' mutation), and additional time for recruiting, getting all centers started, data analysis, and publication, dissemination, and use of the results. And then the results will apply directly only to AZT (and probably indirectly to other drugs in the same class, such as ddI -- although a different test would be used, as different mutations cause HIV to become resistant to ddI). Our concern is not with this trial itself, but with the broader questions of research planning. Does a major study now to fine-tune the use of AZT several years down the road reflect a successful strategy for dealing with the epidemic? In treating bacterial infection, it has long been common to test for resistance, in order to avoid using antibiotics which will not work for a particular patient. HIV is different from bacteria, but a case could be made for using the some other drug as soon as AZT resistance is indicated. Meanwhile, use clinical trials to test truly important leads, such as topotecan or conocurvone, which have been neglected because of the happenstance of politics. The fundamental problem is that for over ten years, a research effort which could not possibly save most people's lives has been acceptable to the general consensus -- almost casually accepted as scientifically inevitable. Little serious effort has been made to think through the consequences and change direction. We wonder if this basic root of the failure of AIDS research can be changed today. ***** Kaposi's Sarcoma, Genistein, and Soybeans by John S. James A paper published a year ago, in the Proceedings of the National Academy of Sciences, USA, suggested that substances found in a plant-based diet, especially one high in soy products, such as the traditional Japanese diet, may help control abnormal angiogenesis (growth of blood vessels).(1) Angiogenesis is centrally important in Kaposi's sarcoma, and is important in solid tumors (which cannot grow beyond a small size unless they can force the growth of new blood vessels to nourish the tumor), and in a number of other diseases. The authors, at universities in Heidelberg, Geneva, and Helsinki, chemically fractionated the urine of volunteers who were eating a soy-rich vegetarian diet. They found one substance, genistein, which had a strong anti-angiogenesis effect in laboratory tests, and which is 30 times more concentrated in the urine of those eating traditional Japanese diets vs. those eating typical Western diets. (Soy contains genistein precursors.) The higher urine concentrations were enough to affect angiogenesis in laboratory tests. This paper did not mention KS, or anything AIDS related. Therefore it is not included on AIDS computer databases, and is largely unknown to the AIDS community. However, abnormal angiogenesis is central to KS. (Two reference on the AIDSLINE database do mention genistein; one of them noted that it suppressed KS cell growth.(2)) The urine of the volunteers was chemically fractionated into six fractions. Four of them had anti-angiogenesis activity. The two most active fractions were NOT analyzed in this study, however; genistein came from one of the less active fractions. (This suggests that plant-based diets may supply other substances which may be better than genistein in anti- angiogenesis activity.) The paper cited other published studies which suggested that the traditional Japanese diet may inhibit breast and prostate cancer. Incidentally -- though not cited in the paper -- there are popular "alternative" cancer treatments (for example, the Gerson diet) which emphasize large quantities of juices, etc. Comment: The Next Step "Macrobiotic" and other plant-based diets have long had advocates in the AIDS community. Unfortunately, these diets have often ignored the known nutritional needs of people with AIDS, as well as food-safety requirements for avoiding infection. Diets not properly designed for persons with HIV disease can do much more harm than good. We see little hope that enough money can be found for clinical trials to scientifically test diets, or nutritional products, for KS or other AIDS-related conditions. Mainstream research is unlikely to develop this area for years. Instead of waiting for trials that may never come, let's take what knowledge does exist and see if something useful can be done with it. What is needed now is for a team, including an HIV- experienced dietitian, to prepare recommendations which meet the nutritional and food-safety needs of persons with AIDS, but also are formulated to have anti-angiogenesis effects, based on what is known at this time. Persons with KS might want to try such a diet to see if it seemed to help. References 1. Fotsis T, Pepper M, Adlercreutz H, and others.

We did not include all hotlines, but those we think will be most useful for our readers. You may want to keep this reference handy, for help with your own questions, or for referring other people. General AIDS Hotlines ** National AIDS Hotline: 800/342-AIDS (800/342-2437), 24 hours; Spanish, 800/344-SIDA (800/344-7432), 8:00 a.m. - 2:00 a.m.; TDD for the deaf, 800/243-7889, 10:00 a.m. - 10:00 p.m. This service, operated by the U.S. Centers for Disease Control, provides confidential information, referrals, and educational materials to callers in the United States, its territories, and Puerto Rico. Its information specialists use a database of over 10,000 service organizations to find appropriate local referrals, for example financial assistance, legal assistance, support groups, buddy programs, housing services, and medical referrals. They can also answer many kinds of general questions about AIDS. We have found that it is usually possible to reach an operator with little or no wait on the phone. But the treatment information from government hotlines is limited at best. The reason is that there are many different ideas about AIDS treatment, and no official body to decide which ones are OK for a government agency to disseminate. For treatment information, you need to check with private organizations; some are listed in this directory, below. [Note: Any '800' telephone number can only offer confidentiality -- not true anonymity -- because the recipient is paying for the call, and therefore receives the telephone number of all callers with its phone bills. We think it is unlikely that this will be a problem for callers. But those who are especially concerned about confidentiality may want to call '800' numbers from a public phone.] ** PWA Coalition of New York Hotline: National, 800/828-3280; local, 212/647-1420.
