Phase I study of evofosfamide, an investigational hypoxia-activated prodrug, in patients with advanced leukemia.
Tumor hypoxia causes resistance to radiation and chemotherapy. Evofosfamide (TH-302) has exhibited specific hypoxia-dependent cytotoxicity against primary acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) samples in vitro. Based on these findings, a Phase I study of evofosfamide was designed for patients with relapsed/refractory leukemia (NCT01149915). In this open-label study, patients were treated with evofosfamide as a 30-60 min/day infusion on Days 1-5 of a 21-day cycle (Arm A, n = 38) or as a continuous infusion over 120 hr over Days 1-5 of a 21-day cycle (Arm B, n = 11). Forty-nine patients were treated including 39 (80%) with AML and 9 (18%) with ALL. Patients had received a median of five prior therapies. In Arm A, the dose-limiting toxicities (DLTs) were grade 3 esophagitis, observed at a dose of 550 mg/m(2) . The maximum tolerated dose (MTD) was a daily dose of 460 mg/m(2) . In Arm B, the DLTs were grade 3 stomatitis and hyperbilirubinemia, observed at a daily dose of 460 mg/m(2) . The continuous infusion MTD was a daily dose of 330 mg/m(2) . Hypoxia markers HIF-1α and CAIX were highly expressed in leukemic bone marrow and were significantly reduced after evofosfamide therapy. The combined overall response rate in Arms A and B was 6% (2 CR/CRi and 1 PR), with all responses seen in Arm A. Evofosfamide has shown limited activity in heavily pretreated leukemia patients. Further evaluation investigating evofosfamide in combination with cytotoxic or demethylating agents is warranted. Am. J. Hematol. 91:800-805, 2016. © 2016 Wiley Periodicals, Inc.

A phase I study of the safety and pharmacokinetics of the hypoxia-activated prodrug TH-302 in combination with doxorubicin in patients with advanced soft tissue sarcoma.
The purpose of this study was to determine the dose-limiting toxicities (DLT), maximum tolerated dose (MTD), safety, pharmacokinetics and preliminary activity of TH-302, a hypoxia-activated prodrug, in combination with doxorubicin in patients with advanced soft tissue sarcoma.. TH-302 was administered intravenously on days 1 and 8 and doxorubicin 75 mg/m² on day 1 (2 h after TH-302) of every 3-week cycle. TH-302 starting dose was 240 mg/m² with a classic 3 + 3 dose escalation. Pharmacokinetics were assessed on days 1 and 8 of cycle 1. Tumor assessments were performed after every second cycle.. Sixteen patients enrolled. Prophylactic growth factor support was added due to grade 4 neutropenia. The MTD was 300 mg/m². DLTs at 340 mg/m² were neutropenia-associated infection and grade 4 thrombocytopenia. Common adverse events included fatigue, nausea and skin rash. There was no evidence of pharmacokinetic interaction between TH-302 and doxorubicin. Five of 15 (33%) evaluable patients had a partial response by RECIST (Response Evaluation Criteria in Solid Tumors) criteria.. The hematologic toxicity of doxorubicin is increased when combined with TH-302. This can be mitigated by prophylactic growth factor support. Toxicities were manageable and there was evidence of antitumor activity.
