A Phase II Study of AKR1C3-Activated Prodrug OBI-3424 (OBI-3424) in Patients With Relapsed/Refractory T-Cell Acute Lymphoblastic Leukemia (T-ALL)

This phase II trial studies how well OBI-3424 works in treating patients with T-cell acute lymphoblastic leukemia that has come back (relapsed) or does not response to treatment (refractory). Drugs used in chemotherapy, such as OBI-3424, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. OBI-3424 may reduce the amount of leukemia in the body.

Phase 1 dose-escalation study evaluating the safety, pharmacokinetics, and clinical activity of OBI-3424 in patients with advanced or metastatic solid tumors.

Article

作者: Pearce, Tillman E. ; Hsu, Pei ; Verschraegen, Claire F. ; Wesolowski, Robert ; Shia, Chi-Sheng ; Tsimberidou, Apostolia Maria

BACKGROUNDReport of a Phase 1 dose-escalation study of OBI-3424 monotherapy in patients with advanced solid tumors (NCT03592264).METHODSA classic 3 + 3 design was used to determine the maximum tolerated dose and recommended Phase 2 dose (RP2D) of OBI-3424 administered intravenously, as a single agent, at doses of 1, 2, 4, 6, 8, or 12 mg/m² (days 1 and 8 of a 21-day cycle, Schedule A) or 8, 10, 12, or 14 mg/m² (day 1 of a 21-day cycle, Schedule B).RESULTSDose-limiting hematologic toxicities at 12 mg/m² in Schedule A led to dose and schedule modifications (Schedule B). In Schedule B, maximum tolerated dose was not reached at the maximum dose tested (14 mg/m²). Grade ≥3 anemia was noted in 3/6 patients treated at 14 mg/m²; the RP2D was 12 mg/m² (Schedule B). Grade ≥3 treatment-emergent adverse events were experienced by 19/39 (49%) and included anemia (41%) and thrombocytopenia (26%); three patients experienced serious treatment-emergent adverse events (grade ≥3 anemia and thrombocytopenia). One patient had a partial response and 21/33 (64%) had stable disease.CONCLUSIONSThe RP2D is 12 mg/m² once every 3 weeks. OBI-3424 was well tolerated; dose-dependent, noncumulative thrombocytopenia and anemia were dose-limiting.

A novel AKR1C3 specific prodrug AST-3424 and its combination therapy in hepatocellular carcinoma

Article

作者: Qin, Shukui ; Zheng, Xia ; Xun, Chen ; Zhang, Yu

OBJECTIVEAST-3424 is a novel specific aldo-keto reductase 1C3 (AKR1C3) prodrug that releases a DNA alkylating reagent upon reduction by AKR1C3. This study aimed to evaluate the efficacy and safety of AST-3424 in patient-derived tumor xenograft (PDTX) model and orthotopic model against hepatocellular carcinoma (HCC).MATERIALS AND METHODPDTX models derived from three HCC patients and orthotopic mice models using HepG2 cells were developed. The mice were treated with AST-3424 alone or combined with other drugs (oxaliplatin, apatinib, sorafenib and elemene in PDTX models, oxaliplatin and 5- fluorouracil in orthotopic models). The tumor volume and weight, as well as the mice weight were assessed. The liver tumor and transplanted tumor were removed for histological, immunohistochemical and Western blot detection in orthotopic model experiments.RESULTSAST-3424 could inhibit tumor growth in HCC PDTX models and orthotopic models, with no difference in safety compared with other marketed drugs, and the drug combination did not increase toxicity. The inhibitory effect of combination treatment was more obvious than which used alone. The reduction of AKR1C3 expression was negatively correlated with AST-3424 dose.CONCLUSIONAST-3424 had a promising effect against HCC in PDTX model and orthotopic model with good safety. It could promote the sensitivity of other drugs without increasing toxicity. Clinical trials are warranted to further certify its antitumor effect and safety.

OBI Pharma Announces Phase 1/2 Study Initiation for OBI-992, a TROP2-Targeted Antibody-Drug Conjugate (ADC) for Cancer Therapy

Clinical trial to evaluate the safety and efficacy of OBI-992 in advanced solid tumors. TAIPEI, Taiwan I June 12, 2024 I OBI Pharma, a clinical-stage oncology company (4174.TWO), today announced the initiation of a Phase 1/2 clinical trial of OBI-992, an antibody-drug conjugate (ADC) targeting TROP2 (Trophoblast cell-surface antigen 2), an antigen overexpressed in multiple tumor types. OBI plans to enroll patients with advanced solid tumors, including non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), gastric cancer (GC), and other potential cancers. The objective of the trial is to verify the safety, pharmacokinetics, and preliminary efficacy profile of OBI-992 in these patient populations. OBI Pharma’s Chief Medical Officer, M. Wayne Saville, M.D., noted, “Based on our preclinical data, OBI-992 has several important advantages over other TROP2 ADCs in development; including high serum stability, excellent bystander effect, potential ability to overcome drug resistance, and outstanding activity in animal and organoid models of cancer 1 , 2 , 3 . We look forward to investigating this potential best-in-class TROP2 ADC in the clinic. Leia Tsimberidou MD, of MD Anderson Cancer Center in Houston, TX. USA is the lead investigator for the study.” Heidi Wang, Ph.D., OBI Pharma’s Chief Executive Officer, added, “We are excited to initiate this first in human study of OBI-992. This is an important company milestone and highlights our commitment to building and strengthening the novel OBI Pharma oncology pipeline. We thank the patients and the investigators for their efforts and dedication.” About OBI-992 OBI-992 is a TROP2-targeted antibody-drug conjugate (ADC) that carries a potent topoisomerase I inhibitor payload (exatecan) proven to kill tumor cells. TROP2 is highly expressed in a variety of solid tumors such as lung, breast, ovarian, gastric, and other cancers, rendering it an ideal target for cancer therapy. OBI-992 uses a unique hydrophilic, enzyme-cleavable linker that is stable in circulation but releases the cytotoxic payload inside tumor cells. In preclinical animal models, OBI-992 demonstrated remarkable antitumor activity, improved pharmacokinetic characteristics, and a favorable safety profile relative to comparator ADCs. The TROP2 targeting antibody was in-licensed from Biosion, Inc. www.Biosion.com , in December 2021. OBI Pharma owns ex-China commercial rights for OBI-992. About OBI Pharma OBI Pharma, Inc., is a clinical stage oncology company that is headquartered in Taiwan and established in 2002. Its mission is to develop novel cancer therapeutic agents for patients with high unmet medical needs. The company’s novel first-in-class immuno-oncology portfolio targeting Globo H includes: two Globo H active immunotherapy vaccines, adagloxad simolenin (formerly OBI-822) and OBI-833. Using the company’s unique ADC platforms, including GlycOBI™, OBI created its novel ADC pipeline which includes OBI-992, OBI-902 and OBI-904, targeting TROP2 and Nectin-4, respectively. OBI’s pipeline also includes the first-in-class AKR1C3-targeted small-molecule prodrug OBI-3424, which selectively releases a potent DNA-alkylating antitumor agent in the presence of the aldo-keto reductase 1C3 (AKR1C3) enzyme.
