OBI-3424 (TH-3424) is a prodrug that is selectively converted by AKR1C3 (aldo-keto reductase 1C3) to a potent DNA-alkylating agent. OBI-3424 can be used for hepatocellular carcinoma, castrate-resistant prostate cancer, and acute lymphoblastic leukemia (ALL) research[1].
OBI-3424 exerts potent cytotoxicity against the H460 lung cancer cell line (IC50 of 4.0 nM). OBI-3424 exhibits potent cytotoxicity, in particular against cell lines derived from T-ALL with high AKR1C3 expression, with IC50 values in the low nM range[1].OBI-3424 also exerts potent cell killing against ALL PDXs, and the median IC50 values were 60.3 nM for B-ALL, 9.7 nM for T-ALL and 31.5 nM for ETP-ALL[1].
OBI-3424 (0.5-2.5 mg/kg; i.p.; once weekly; for 3 weeks) treatment induces regressions in PDXs mice and results in prolongation of mouse event-free survival[1].

OBI-3424, a Novel AKR1C3-Activated Prodrug, Exhibits Potent Efficacy against Preclinical Models of T-ALL
Clin Cancer Res 2019 Jul 15;25(14):4493-4503.PMID:31015346DOI:PMC6635081
Purpose: OBI-3424 is a highly selective prodrug that is converted by aldo-keto reductase family 1 member C3 (AKR1C3) to a potent DNA-alkylating agent. OBI-3424 has entered clinical testing for hepatocellular carcinoma and castrate-resistant prostate cancer, and it represents a potentially novel treatment for acute lymphoblastic leukemia (ALL). Experimental design: We assessed AKR1C3 expression by RNA-Seq and immunoblotting, and evaluated the in vitro cytotoxicity of OBI-3424. We investigated the pharmacokinetics of OBI-3424 in mice and nonhuman primates, and assessed the in vivo efficacy of OBI-3424 against a large panel of patient-derived xenografts (PDX). Results: AKR1C3 mRNA expression was significantly higher in primary T-lineage ALL (T-ALL; n = 264) than B-lineage ALL (B-ALL; n = 1,740; P < 0.0001), and OBI-3424 exerted potent cytotoxicity against T-ALL cell lines and PDXs. In vivo, OBI-3424 significantly prolonged the event-free survival (EFS) of nine of nine ALL PDXs by 17.1-77.8 days (treated/control values 2.5-14.0), and disease regression was observed in eight of nine PDXs. A significant reduction (P < 0.0001) in bone marrow infiltration at day 28 was observed in four of six evaluable T-ALL PDXs. The importance of AKR1C3 in the in vivo response to OBI-3424 was verified using a B-ALL PDX that had been lentivirally transduced to stably overexpress AKR1C3. OBI-3424 combined with nelarabine resulted in prolongation of mouse EFS compared with each single agent alone in two T-ALL PDXs. Conclusions: OBI-3424 exerted profound in vivo efficacy against T-ALL PDXs derived predominantly from aggressive and fatal disease, and therefore may represent a novel treatment for aggressive and chemoresistant T-ALL in an AKR1C3 biomarker-driven clinical trial.
