A Phase I, Dose-Escalating Safety and Tolerance Study of sCD4-PE40 in HIV-Infected Persons
Launched by NATIONAL INSTITUTE OF ALLERGY AND INFECTIOUS DISEASES (NIAID) · Aug 30, 2001
Current as of November 28, 2023
There is some evidence that AZT and sCD4-PE40, an experimental drug with anti-HIV activity previously demonstrated in vitro, may produce increased benefit when used in combination in HIV-infected patients. Cohorts of six patients each receive escalating doses of sCD4-PE40 in a single IV weekly dose for 8 weeks. All six patients at a given dose must complete 2 weeks of therapy without dose-limiting toxicity before dose escalation in subsequent patient cohorts may occur. The MTD is defined as the dose of sCD4-PE40 immediately below that at which two or more of six patients experience grade 3...

- Active pulmonary disease.
- Chronic active hepatitis B surface antigenemia or unstable hepatitis C.
- Current diagnosis of malignancy for which systemic therapy would be required during the study.
- Inadequate intravenous access.
- Concurrent Medication:
- Hepatotoxic agents.
- Other antiretroviral or immunomodulator agents (including but not limited to AZT, ddI, ddC, interferon, and steroids).
- Other investigational drugs.
- Systemic therapy for malignancy.
- G-CSF and GM-CSF.
- Prior Medication:
- Other antiretroviral or immunomodulator agents (including but not limited to AZT, ddI, ddC, interferon, and steroids) within 4 weeks prior to study entry.
