Updated data from 16 patients with fully resected stage III/IV metastatic melanoma in an open-label, U.K. Phase I/II trial showed that SCIB1 led to a median survival of 26 months from study entry.

The trial also includes an extension phase in which patients can receive SCIB1 every 3-6 months for up to 5 years. Scancell reported initial data from the Phase II portion last year and updated data in July (see BioCentury, Jan. 13 & July 21). The Phase II portion of the trial is also enrolling an 8 mg SCIB1 cohort of up to 13 patients.

Updated data from the Phase I portion of the trial showed that in patients who received >=3 doses of 2 or 4 mg SCIB1, median survival is 34 months from study entry. SCIB1 led to 1-, 2- and 3-year survival rates of 100%, 67% and 50%, respectively. In patients with stage IV disease who received 8 mg SCIB1, median survival is 13 months from study entry. ...
