About OBI-3424
OBI-3424 is a first-in-class novel small-molecule prodrug that selectively targets cancers that overexpress the enzyme aldo-keto reductase 1c3 (AKR1C3), and selectively releases a potent DNA alkylating agent in the presence of the AKR1C3 enzyme.

AKR1C3 overexpression has been documented in a number of treatment-resistant and difficult to treat cancers including: hcastrate-resistant prostate cancer (CRPC) and T-cell acute lymphoblastic leukemia (T-ALL).

Furthermore, individualized patient selection by staining for AKR1C3 overexpression by immunohistochemistry can be performed to identify patients with other tumor types most likely to respond to treatment with OBI-3424, offering the possibility for a streamlined clinical development strategy.

OBI Pharma plans an Investigational New Drug (IND) application filing with the U.S. Food and Drug Administration (FDA) in early 2018.

OBI Pharma has OBI-3424 worldwide rights with the exception of the following countries, of which Ascenta Pharma has rights: China, Hong Kong, Macao, Taiwan, Japan, South Korea, Singapore, Malaysia, Thailand, Turkey and India.
