|Sixteen-Week Analysis of
Heavily Pre-Treated Patients Receiving T-20 As A Component of Multi-Drug Salvage Therapy
Presented at the 39th Interscience Conference on Antimicrobial Agents and
San Francisco, CA, September 26-29, 1999
||To evaluate the safety and antiviral activity
of T-20, in combination with oral antiretroviral agents in heavily pre-treated
||Phase II open-label roll-over protocol
- T-20 (50 mg/twice daily via self-administered subcutaeous injection) in combination with
oral antiretrovirals. Combinations were individualized to each patient and were chosen
based on genotypic analysis.
||55 HIV-1 positive adult patients who had
enrolled in earlier clinical trials (TRI-001, TRI-002 or TRI-003)
- Patients had previously been treated with a median of 11 antiretrovirals and 93% had a
clinical history of triple class exposure (i.e. NRTIs, NNRTIs and PIs).
- At entry, 93% of patients showed mutations associated with protease inhibitors (median
of five) and 87% showed mutations associated with reverse transcriptase inhibitors (median
- Median baseline viral load: 79,400 copies/mL
- Median baseline CD4+ cells: 70 cells/mm3
||Results at 16 weeks:
- 60% (33/55) of patients had a decrease in viral load >1.0 log10 from
baseline and/or achieved reduction in viral load to <400 copies/mL.
- 36% (20/55) of patients achieved viral loads below limit of detection of Roche Amplicor
Assay (<400 copies/mL).
||In all clinical studies to date, most adverse
events reported on T-20 were mild or moderate in severity. The most frequent adverse
events included fever, headache and lymph node abnormalities, in addition to local
irritation resulting from the subcutaneous injection.
||T-20, in combination with oral
antiretrovirals, provides clinically relevant suppression of HIV through week 16 and may
constitute a new treatment strategy for treating patients with prior antiviral experience.
