A Randomized, Comparative Trial of Trimetrexate With Leucovorin Rescue Versus Standard Anti-Pneumocystis Therapy Versus Standard Anti-Pneumocystis Therapy With High Dose Steroids for AIDS Patients With Pneumocystis Pneumonia Who Appear to Be Refractory to Conventional Drugs
This study compares three different therapies for treatment of refractory Pneumocystis carinii pneumonia (PCP) in patients with AIDS. "Refractory" means that the patient has failed to respond to at least 4 days of treatment with either of two standard therapies: (1) sulfamethoxazole/trimethoprim (SMX/TMP) or (2) pentamidine (PEN). This study compares therapy with trimetrexate (TMTX) and leucovorin (LCV) to standard therapy and standard therapy plus high-dose steroids (methylprednisolone). The purpose is to find better and safer forms of treatment for PCP in AIDS patients. There is at present no scientific information about the best treatment for an AIDS patient with PCP who is not improving while receiving the standard therapies (SMX/TMP or PEN). New drug treatments are available, including steroid therapy and TMTX, but there is no information proving that these new treatments work better than the standard therapies.

A Phase I Study of AZT and Human Interferon Alpha (Recombinant Alpha-2A and Lymphoblastoid) in the Treatment of AIDS-Associated Kaposi's Sarcoma
To evaluate the safety and toxicity of combination therapy for AIDS-associated Kaposi's sarcoma with zidovudine (AZT) and two kinds of interferon alpha. The two kinds are interferon alpha (IFN-A) and interferon alpha-2A (recombinant) (IFN-A2A). To define the pharmacokinetics of both AZT and IFN-A or IFN-A2A when given in combination; to define the maximum tolerated dose of each drug in combination and to define doses to be used in Phase II trials. AZT has been found to inhibit both the in vitro (in test tube) and cell killing effects of HIV, and both interferons (IFN-A and IFN-A2A) have shown antiviral and antitumor effect in Kaposi's sarcoma. It is reasonable to assume that a synergistic effect and enhanced antitumor response may be seen with combination therapy. A study to evaluate the safety and efficacy of AZT in combination with IFN-A or IFN-A2A is warranted.

A Phase I Safety, Efficacy, and Pharmacokinetic Study of 2',3'-Dideoxyinosine (ddI) Administered Twice Daily to Patients With AIDS or AIDS Related Complex
To determine the safety, pharmacokinetics (blood levels), and effectiveness of didanosine (ddI) when administered both intravenously and orally. After the maximum tolerated dose (MTD) is determined, an appropriate dosage regimen will then be established for Phase II and Phase III trials. Zidovudine (AZT) has produced the best clinical results in the drug therapy of AIDS to date, but it produces toxicity in approximately 50 percent of patients. Early data show that ddI possesses high antiviral activity and less toxicity than AZT. The most effective route and dose of ddI has yet to be determined.

An Open Trial of Zidovudine (AZT) Treatment of the AIDS Dementia Complex in Patients With AIDS or Low CD4+ Lymphocyte Counts
To provide accurate and complete neurologic assessment of the course of the AIDS dementia complex in patients treated with zidovudine (AZT). The study will determine how frequently patients improve, how long improvement is sustained, and the magnitude and functional significance of improvement. Individuals with AIDS frequently suffer central nervous system (CNS) problems that are characterized by cognitive, motor, and behavioral deficits, in a disorder known as AIDS dementia complex. Clinical experience suggests that its course is often progressive, going from initial symptoms to moderate or severe dementia within several months. Accumulating evidence now suggests that direct brain infection by the HIV virus is the likely cause of the AIDS dementia complex. Case reports suggest that therapy with AZT, which has been shown to be a strong inhibitor of HIV replication in vitro, may alleviate the AIDS dementia complex. This study will help define the natural history of the AIDS dementia complex in treated patients.

A Phase I Evaluation of Azidothymidine (AZT) in Children With Acquired Immune Deficiency Syndrome (AIDS) or AIDS Related Complex (ARC)
The study is designed to test the drug zidovudine (AZT) in children, including study of drug levels in various parts of the body fluids, safety of the drug, and its effect on different parts of the body. The effects of any drug, the way a drug enters the bloodstream, the way it is used by the body, and the way the body eliminates the drug may be very different in children compared with adults. The largest group of children who have AIDS are those who are less than 2 years of age. AIDS is often first identified in infants who are about 6 months old. Studies of AZT show that it might be useful in the treatment of AIDS. Thus it is important to study the effects of the drug in children.

A Phase I Trial of Recombinant Human Granulocyte-Macrophage Colony Stimulating Factor (rHuGM-CSF), Recombinant Alpha Interferon and Azidothymidine (AZT) in AIDS-Associated Kaposi's Sarcoma
To define the best doses of sargramostim ( granulocyte-macrophage colony-stimulating factor; GM-CSF ), interferon alfa-2b ( IFN-A2b ), and zidovudine ( AZT ) to give together in patients with AIDS-associated Kaposi's sarcoma ( KS ), to learn about the side effects of these drugs when they are given together for 8 weeks, and to find out whether the combination of GM-CSF, IFN-A2b, and AZT has any effect on KS, HIV, or the immune system. Studies show that IFN-A2b can cause KS tumors to shrink or disappear in about 30 percent of patients. IFN-A2b can greatly reduce the growth of the HIV virus in test tube experiments and perhaps in patients. AZT has also been shown to reduce the growth of HIV and show improvements in the immune system with fewer infections. Test tube experiments show that when IFN-A2b and AZT are used together, they reduce the growth of the HIV virus much more effectively than when either drug is used alone. In recent studies of the combination of interferon alpha and AZT in patients with KS, more than 40 percent of the patients showed shrinkage of their tumors, and some showed evidence for suppression of HIV growth in the body. However, the combination of IFN-A2b with AZT often caused a marked lowering of the white blood cell (WBC) count, especially a type of WBC called the granulocyte (or neutrophil) which is important in the body's defense against infection. Recombinant human GM-CSF is a human protein which is produced in bacteria. It has been shown to cause an increase in the WBC count.

Suppression of Cytomegalovirus Retinitis Utilizing High Dose Intravenous Acyclovir and Oral Zidovudine in Patients With AIDS
To study the use of acyclovir (ACV) and zidovudine (AZT) in the treatment of cytomegalovirus (CMV) retinitis in patients with AIDS who would otherwise be treated with ganciclovir (DHPG) alone. CMV retinitis is one of the most common opportunistic infections in patients with AIDS. DHPG is at present the only drug available for widespread compassionate use in the United States. Although most patients respond to treatment with DHPG, the medication does not cure the infection. Most patients will have a relapse and will require retreatment with DHPG. Because of the large relapse rate, most people treated for CMV retinitis are placed on continuous treatment with DHPG. There are two major problems associated with ongoing use of DHPG: 1) The development of a low white blood cell (WBC) count (leukopenia) which is a known side effect of the drug; and 2) the increased risk for leukopenia when DHPG is given together with AZT, the only antiviral drug currently available for the treatment of HIV infection. Therefore, patients cannot take both AZT and DHPG at the same time because the bone marrow toxicity is made much more severe when the drugs are given together. This has resulted in the difficult decision as to whether to forgo potential life-extending therapy with AZT in order to preserve sight. An effective treatment for CMV retinitis is needed that will allow the patient to also take AZT. ACV is presently the drug of choice for severe herpes virus infections. It has been shown to be effective in suppressing severe CMV disease in patients who have received bone marrow transplants.

Phase I Rising Dose Tolerability Study of SC-48334 in Patients With Acquired Immunodeficiency Syndrome (AIDS) and Advanced AIDS Related Complex
To determine the following about the use of SC-48334 in patients with AIDS and advanced AIDS related complex (ARC): 1. The largest maximum tolerated dose (MTD); 2. Effectiveness against HIV; 3. Pharmacokinetics - how fast SC-48334 reaches the bloodstream, what concentration is reached, and how long it remains in the patient's blood. SC-48334 is a chemical that prevents the biochemical actions of certain enzymes in the body, and recent studies have shown that it may also prevent the activity of HIV. The study will attempt to show whether SC-48334 can safely and effectively break the cycle of HIV infection in AIDS and advanced ARC by progressively eliminating HIV.

Phase I Trial of mBACOD and Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) in AIDS-Associated Large Cell, Immunoblastic, and Small Non-cleaved Lymphoma
To determine the toxicity and effectiveness of adding sargramostim (recombinant granulocyte-macrophage colony stimulating factor; GM-CSF) to a standard chemotherapy drug combination (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine, and dexamethasone) known as mBACOD in the treatment of non-Hodgkin's lymphoma in patients who are infected with HIV. Treatment of patients with AIDS-associated lymphoma is achieving inferior results when compared with outcomes for non-AIDS patients. Treatment with mBACOD has been promising, but the toxicity is very high. Patients treated with mBACOD have very low white blood cell counts. GM-CSF has increased the number of white blood cells in animal studies and preliminary human studies. It is hoped that including GM-CSF among the drugs given to lymphoma patients will prevent or lessen the decrease in white blood cells caused by mBACOD.

A Randomized, Controlled Study of Intravenous Ganciclovir Therapy for Peripheral Cytomegalovirus Retinitis in Patients With AIDS
To provide information about the usefulness and safety of giving injections of ganciclovir (DHPG) for treating peripheral cytomegalovirus (CMV) retinitis. CMV retinitis is an important sight-threatening opportunistic infection which affects 1 to 2 out of every 10 patients with AIDS. Results from an earlier study suggest that about 80 percent of patients with CMV retinitis will be helped by receiving intravenous doses of DHPG.
