Phase II study of the safety and antitumor activity of the hypoxia-activated prodrug TH-302 in combination with doxorubicin in patients with advanced soft tissue sarcoma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2014, Oct-10, Volume: 32, Issue:29

    TH-302, a prodrug of the cytotoxic alkylating agent bromo-isophosphoramide mustard, is preferentially activated in hypoxic conditions. This phase II study investigated TH-302 in combination with doxorubicin, followed by single-agent TH-302 maintenance therapy in patients with first-line advanced soft tissue sarcoma (STS) to assess progression-free survival (PFS), response rate, overall survival, safety, and tolerability.. In this open-label phase II study, TH-302 300 mg/m(2) was administered intravenously on days 1 and 8 with doxorubicin 75 mg/m(2) on day 1 of each 21-day cycle. After six cycles, patients with stable and/or responding disease could receive maintenance monotherapy with TH-302.. Ninety-one patients initiated TH-302 plus doxorubicin induction treatment. The PFS rate at 6 months (primary efficacy measure) was 58% (95% CI, 46% to 68%). Median PFS was 6.5 months (95% CI, 5.8 to 7.7 months); median overall survival was 21.5 months (95% CI, 16.0 to 26.2 months). Best tumor responses were complete response (n = 2 [2%]) and partial response (n = 30 [34%]). During TH-302 maintenance (n = 48), five patients improved from stable disease to partial response, and one patient improved from partial to complete response. The most common adverse events during induction were fatigue, nausea, and skin and/or mucosal toxicities as well as anemia, thrombocytopenia, and neutropenia. These were less severe and less frequent during maintenance. There was no evidence of TH-302-related hepatic, renal, or cardiac toxicity.. PFS, overall survival, and tumor response compared favorably with historical outcomes achieved with other first-line chemotherapies for advanced STS. A phase III study of TH-302 is ongoing (NCT01440088).

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.
    Oncology, 2011, Volume: 80, Issue:1-2

    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.

The fate of new fosfamides in phase III studies in advanced soft tissue sarcoma.
    European journal of cancer (Oxford, England : 1990), 2017, Volume: 84

    For decades, doxorubicin alone or in combination with ifosfamide has been used in advanced soft tissue sarcoma (STS). In 2014, a comparison of doxorubicin alone versus the combination with ifosfamide (in the randomised phase III EORTC 62012) showed no difference in overall survival (OS), but a difference in response and progression-free survival (PFS) were observed in favour of the combination but at the expense of increased toxicity. Newer fosfamides, with slightly different modes of action, and potentially less toxicity, namely evofosfamide and palifosfamide have recently been tested in randomised phase III clinical trials in STS. The TH CR-406/SARC021 (June 2017) and the PICASSO III (September 2016) studies compared doxorubicin, as the standard arm, to doxorubicin in combination with evofosfamide and palifosfamide, respectively. In both studies, the combination arm produced increased response rates but at the expense of higher toxicity. However, there was no difference in OS or PFS in favour of the combination. Importantly, the median OS of patients receiving standard of care, doxorubicin, in both studies appeared improved from 12.8 months (95.5% CI 10.5-14·III) in the EORTC 62012 to 16.9 months (95% CI 14.8 to 22.9) in PICASSO III and 19.0 months (95% CI 16.2-22.4) in TH CR-406/SARC021. The results of these three randomised phase III studies highlight several critical issues related to the design and conduct of such trials in STS. We discuss these issues aiming to contribute to the ongoing debate about the optimal approach to perform clinical research in STS.

Hypoxia-activated chemotherapeutic TH-302 enhances the effects of VEGF-A inhibition and radiation on sarcomas.
    British journal of cancer, 2015, Jun-30, Volume: 113, Issue:1

    Human sarcomas with a poor response to vascular endothelial growth factor-A (VEGF-A) inhibition and radiation therapy (RT) have upregulation of hypoxia-inducible factor 1α (HIF-1α) and HIF-1α target genes. This study examines the addition of the hypoxia-activated chemotherapy TH-302 to VEGF-A inhibition and RT (a.k.a. trimodality therapy).. Trimodality therapy was examined in two xenograft models and in vitro in tumour endothelial cells and sarcoma cell lines.. In both mouse models, VEGF-A inhibition and radiation showed greater efficacy than either therapy alone in slowing sarcoma growth. When TH-302 was added, this trimodality therapy completely blocked tumour growth with tumours remaining dormant for over 3 months after cessation of therapy. Trimodality therapy caused 2.6- to 6.2-fold more endothelial cell-specific apoptosis than bimodality therapies, and microvessel density and HIF-1α activity were reduced to 11-13% and 13-20% of control, respectively. When trimodality therapy was examined in vitro, increases in DNA damage and apoptosis were much more pronounced in tumour endothelial cells compared with that in sarcoma cells, especially under hypoxia.. The combination of TH-302, VEGF-A inhibition, and RT is highly effective in preclinical models of sarcoma and is associated with increased DNA damage and apoptosis in endothelial cells and decreased HIF-1α activity.
