A phase I, dose-escalation study of oral PIM447 in Japanese patients with relapsed and/or refractory multiple myeloma.

PIM447, a pan-proviral integration site for Moloney leukemia (PIM) kinase inhibitor, has shown preclinical activity in multiple myeloma (MM). This phase I, open-label, multicenter, dose-escalation study aimed to determine the maximum tolerated dose (MTD) and recommended dose for expansion (RDE) of PIM447 in Japanese patients with relapsed and/or refractory (R/R) MM. The study included 13 patients (250 mg once daily (QD), [n = 7]; 300 mg QD, [n = 6]).

Efficacy and safety of tisagenlecleucel in Japanese pediatric and young adult patients with relapsed/refractory B cell acute lymphoblastic leukemia.

Tisagenlecleucel is an autologous T cell genetically modified ex vivo using a lentiviral vector encoding an anti-CD19 chimeric antigen receptor. Here, we present the efficacy and safety of tisagenlecleucel in a subgroup of Japanese patients with relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (ALL). ELIANA was a single-arm, open-label, multicenter, phase 2 study.

Phase I dose-escalation study of capmatinib (INC280) in Japanese patients with advanced solid tumors.

Capmatinib is a highly specific, potent and selective MET inhibitor. This was an open-label, multicenter, dose-escalation, phase I study conducted in Japanese patients with advanced solid tumors (not selected based on their MET status). The primary objective was to determine the maximum tolerated dose (MTD) and/or highest studied dose being safe.

Phase I study of alpelisib (BYL719), an α-specific PI3K inhibitor, in Japanese patients with advanced solid tumors.

This phase I study aimed to determine tolerability and preliminary efficacy of single-agent alpelisib (BYL719) in Japanese patients with advanced solid malignancies. The primary objective of the study was to estimate the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) of oral alpelisib in patients with advanced solid tumors who had progressed despite standard therapy. The expansion part included patients with PIK3CA mutation/amplification; safety, preliminary efficacy, pharmacokinetic (PK)/pharmacodynamic profile, and food effect on the PK profile of alpelisib at the MTD/RP2D were determined.

A phase I study of single-agent BEZ235 special delivery system sachet in Japanese patients with advanced solid tumors.

Purpose: BEZ235 is a dual kinase inhibitor of phosphatidylinositol 3-kinase (PI3K) and mammalian target of rapamycin, which are key components of the PI3K pathway. This was an open-label, multicenter, dose-escalation, phase I study of single-agent BEZ235 in Japanese oncology patients to determine the maximum tolerated dose (MTD) of BEZ235 based on dose-limiting toxicities (DLTs).

Methods: Dose escalation was guided by a standard 3 + 3 method and was based on DLTs observed in Cycle 1 and other safety, pharmacokinetic, and pharmacodynamic information.

A randomized dose-escalation study to assess the safety, tolerability, and pharmacokinetics of ruxolitinib (INC424) in healthy Japanese volunteers.

Ruxolitinib (INC424), a potent and selective oral Janus kinase 1 and 2 inhibitor, was recently approved by the US food and drug administration for the treatment of intermediate or high-risk myelofibrosis. The safety, tolerability, and pharmacokinetics (PK) of ruxolitinib have been extensively evaluated in healthy subjects and patients. The present study is the first to investigate the PK and tolerability of ruxolitinib in the Japanese population.

Design and synthesis of a metabolically stable and potent antitussive agent, a novel delta opioid receptor antagonist, TRK-851.

We have previously reported on antitussive effect of (5R,9R,13S,14S)-17-cyclopropylmethyl-6,7-didehydro-4,5-epoxy-5',6'-dihydro-3-methoxy-4'H-pyrrolo[3,2,1-ij]quinolino[2',1':6,7]morphinan-14-ol(1b) methanesulfonate (TRK-850), a selective delta opioid receptor antagonist which markedly reduced the number of coughs in a rat cough model. We designed TRK-850 based on naltrindole (NTI), a typical delta opioid receptor antagonist, to improve its permeability through the blood-brain barrier by introducing hydrophobic moieties to NTI. The ED(50) values of NTI and compound 1b by intraperitoneal injections were 104 microg/kg and 2.
