Study summary

To determine the toxic effects of AS-101 at various doses in patients with AIDS or AIDS related complex. Also to determine the effect of various doses of AS-101 on immune functions and the occurrence of infections in these patients. AIDS is a viral disease that is characterized by a loss of some immune function and the development of frequent, eventually fatal, infectious diseases. Although zidovudine (AZT) has prolonged survival in some patients with AIDS, AZT is quite toxic and there is a need for more effective and less toxic drugs. AS-101 is a synthetic organic compound containing the metal tellurium that is being tested because in laboratory studies it improved immune functions.

Read the detailed description

AIDS is a viral disease that is characterized by a loss of some immune function and the development of frequent, eventually fatal, infectious diseases. Although zidovudine (AZT) has prolonged survival in some patients with AIDS, AZT is quite toxic and there is a need for more effective and less toxic drugs. AS-101 is a synthetic organic compound containing the metal tellurium that is being tested because in laboratory studies it improved immune functions.

Patients are given intravenous infusions of AS-101 3 times a week for 12 weeks. The first group of 6 patients receives a dose that did not cause toxic effects in a preliminary study. If no adverse effects occur, the next 6 patients receive a higher dose level and so on, until an optimum dose has been reached. The investigators will determine the optimum dose based on the type and severity of adverse effects experienced by the patients on the study and by the effect of the drug on the immune function of the patient and its effect on the HIV infection. Samples of blood and urine are taken periodically during the study and skin tests are performed 3 times to aid in the evaluation of AS-101. Patients receive standard treatment for any infections that develop during the study.

Exclusion criteria

Exclusion Criteria

Co-existing Condition:

Patients with the following conditions or symptoms are excluded:

  • Active opportunistic infection or requiring concurrent treatment.
  • Serious medical problems, such as diabetes, renal disease, ASHD, or hypertension, which would complicate interpretation of treatment results.
  • Transfusion requirements exceeding 2 transfusions per month in order to achieve > 9 g/dl.

Concurrent Medication:

Excluded:

  • Treatment for active opportunistic infection or malignancy.
  • Systemic antiviral preparations.
  • agents.
  • Immunostimulation therapy.
  • Specific therapy for Kaposi's sarcoma or other malignancies.

Concurrent Treatment:

Excluded:

  • More than 2 units of red blood cell transfusions per month in order to achieve hemoglobin > 8 g/dl.

Patients unlikely or unable, for reasons such as distance from the hospital or psychological considerations, to comply with the requirements of the protocol, especially in regard to regular attendance for treatment, are excluded.

Prior Medication:

Excluded:

  • Systemic antiviral preparations.
  • Isoprinosine.
  • Excluded with 1 month of study entry:
  • Immunosuppressive agents.
  • Immunomodulators.

Prior Treatment:

Excluded:

  • Immunostimulation therapy, such as BCG vaccine.

Active drug or alcohol abuse.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.
