Study of SS1(dsFv)-PE38 (SS1P) Anti-Mesothelin Immunotoxin in Advanced Malignancies: Continuous Infusion for 10 Days

Withdrawn before enrolling · Phase 1

Conditions studied: Neoplasms

In brief

Although Neopharm has terminated its sponsorship of this study, it is continuing under the sponsorship of the NCI. Please see "Experimental Drug SS1(dsFv)-PE38 to Treat Cancer" (Study ID number 010011). SS1(dsFv)-PE38 is an oncology drug product containing a bacteria toxin, fused to a high affinity, disulfide stabilized antibody. The fused protein retains cell killing activity, but binds only to cells expressing mesothelin. Tumors characterized by very high surface mesothelin expression include mesothelioma; epithelial carcinomas of ovary and peritoneum; and squamous cancers of cervix and upper aerodigestive tract, including esophagus, head, and neck cancers. This is a dose-escalating study to determine the maximum tolerated dose (MTD) of intravenous SS1(dsFv)-PE38 administered continuously for 10 days every four weeks for a maximum of four courses of treatment. Dose escalation will proceed in cohorts of 3 until dose-limiting toxicity (DLT) is observed.
