Trial in Progress: Phase 1b Bridging Study of the Pharmacokinetics (PK), Safety, and Efficacy of Orally Administered Olverembatinib (HQP1351) in Patients with Refractory Chronic Myeloid Leukemia (CML) and Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia (Ph⁺ ALL)
Notice bibliographique
Résumé
Abstract Background: Management of CML using tyrosine kinase inhibitors (TKIs) is often constrained by treatment failure, which portends a poor prognosis, particularly among patients who fail second-generation TKIs because of resistance. Treatment failure may be due to therapeutic resistance (whether BCR-ABL1 mutation-dependent or independent), intolerance, and/or suboptimal adherence. The BCR-ABL1 T315I ("gatekeeper") genotype is insensitive to first- and second-generation TKIs, and compound mutations complicate management with all members of the class (including third-generation TKI ponatinib). Olverembatinib (HQP1351) is a novel, potent, orally active BCR-ABL1 TKI with promising activity against CML, including antitumor activity regardless of genotype, and a preliminarily favorable safety profile. Methods: This open-label bridging trial is evaluating the PK, efficacy, and safety of olverembatinib administered orally every other day (QOD) in adults who have chronic-phase, accelerated-phase, or blast-phase CML (CP-CML, AP-CML, or BP-CML) and Ph⁺ ALL, with or without the T315I mutation, and have experienced resistance to or intolerance (including NCI CTCAE v5.0 grade ≥ 2 adverse events) of at least 3 TKIs. Eligible patients have no residual grade ≥ 2 adverse events (other than alopecia or skin pigmentation change) due to prior treatments, a maximum ECOG performance status of 2, and a minimum life expectancy of 3 months. Study participants are being randomly allocated in a 1:1:1 ratio to 3 dose cohorts: 30, 40, or 50 mg of oral olverembatinib QOD over a cycle length of 28 days, with 10 patients per cohort and randomization stratified according to CML phase (CP-CML, AP-CML, or BP-CML) or Ph⁺ ALL and T315I mutational status. Study endpoints comprise the PK profile of olverembatinib at Cycle 1 Day 1 and Day 27; efficacy endpoints of major cytogenetic and hematologic responses; and safety. The recommended phase 2 dose of olverembatinib will be determined based on a comprehensive assessment of PK, safety, and efficacy data in US and Chinese patients. As of July 14, 2021, 14 of 30 patients have been enrolled. Internal study identifier HQP1351-CU-101. Clinicaltrial.gov identifier: NCT04260022.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
