Study of AU-007, A Monoclonal Antibody That Binds to IL-2 and Inhibits IL-2Rα Binding, in Patients With Unresectable Locally Advanced or Metastatic Cancer

Advanced Solid Tumor Clinical Trial

Official title: A Phase 1/2, First-in-Human, Open Label, Dose Escalation and Expansion Study of AU-007, A Monoclonal Antibody That Binds to IL-2 and Inhibits IL-2Rα Binding, in Patients With Unresectable Locally Advanced or Metastatic Cancer

Status Recruiting

Clinical Trial Summary

This is a first in human, open-label, multi-center Phase 1 / 2 study to evaluate the safety, tolerability, and initial efficacy of AU-007 in patients with advanced solid tumors. AU-007 will be administered either as a monotherapy, or in combination with a single loading dose of aldesleukin, or with both AU-007 and aldesleukin given every 2 weeks (Q2w)

Clinical Trial Description

This is a first in human, multicenter, open-label Phase 1-2 study evaluating the safety, tolerability, and initial efficacy of AU-007 with or without aldesleukin, in patients with unresectable locally advanced or metastatic cancer. Patients must either be ineligible for or have progressed on prior standard of care therapy. Phase 1 consists of 3 escalation Arms, each starting with a single 1+2 escalation cohort followed by 3+3 escalation cohorts to define the recommended Phase 2 dose (RP2D) or maximum tolerated dose (MTD). The study begins in Arm A evaluating escalating doses of AU-007 (Q2w) in sequential escalation cohorts to define the recommended Phase 2 dose (RP2D) or maximum tolerated dose (MTD). In Arm B, AU-007 (Q2w) is evaluated in combination with a single dose of aldesleukin given with the first AU-007 dose. AU-007 is administered at a fixed dose (Q2w) with an escalating single aldesleukin dose in sequential escalation cohorts. In Arm C, AU-007 is evaluated in combination with aldesleukin both given Q2w. AU-007 will be administered at a fixed dose with an escalating dose of aldesleukin in each sequential Arm C escalation cohort. The Phase 2, cohort expansion portion of the study consists of three expansion Arms evaluating the initial efficacy of the RP2D from corresponding dose escalation Arms A, B, and C in selected solid tumor types. Initially, melanoma and renal cell cancer will be evaluated in each Arm. Other eligible cancers include but not limited to Merkel Cell Carcinoma, non-small cell lung cancer and urothelial cancer. ;
