Clinical Trial Summary

Protocol PEN-866-001 is an open-label, multi-center, first-in-human Phase 1/2a study evaluating PEN-866 in patients with advanced solid malignancies whose disease has progressed after treatment with previous anticancer therapies.

Description:

Phase 1a will employ an adaptive model guided with overdose control principle to make dose recommendations and estimate the maximum tolerated dose (MTD) of PEN-866 (single agent).

Phase 1b will employ a standard 3 + 3 design to make dose recommendations and estimate the MTD of PEN-866 in combination therapy.

Phase 2a (single agent) will assess the safety, tolerability, pharmacokinetic, and pharmacodynamics profile of PEN-866 (single agent) at the recommended Phase 2 dose determined at the conclusion of Phase 1a in patients with advanced solid malignancies.
