Adult T-cell leukemia/lymphoma (ATL) is an aggressive non-Hodgkin lymphoma with poor prognosis and few treatment options for patients relapsed, recurrent, or refractory disease. We evaluated the efficacy safety of valemetostat, a potent enhancer zeste homolog 2 (EZH2) EZH1 inhibitor, in treating relapsed (R/R) ATL. This multicenter phase trial enrolled R/R ATL (acute, lymphoma, unfavorable chronic type). Patients received valemetostat 200 mg/day orally until progressive disease unacceptable...

Abstract Background Approximately 70% of lower-grade gliomas harbor isocitrate dehydrogenase 1 (IDH1) mutations, resulting in the accumulation oncometabolite D-2-hydroxyglutarate (D-2-HG); this leads to epigenetic dysregulation, oncogenesis, and subsequent clonal expansion. DS-1001 is an oral brain-penetrant mutant IDH1 selective inhibitor. This first-in-human study investigated safety, pharmacokinetics, pharmacodynamics, efficacy DS-1001. Methods was a multicenter, open-label,...

Abstract Milademetan (DS‐3032, RAIN‐32) is an orally available mouse double minute 2 (MDM2) antagonist with potential antineoplastic activity owing to increase in p53 through interruption of the MDM2‐p53 interaction. This phase I, dose‐escalating study assessed safety, tolerability, efficacy, and pharmacokinetics milademetan 18 Japanese patients solid tumors who relapsed after or were refractory standard therapy. Patients aged ≥ 20 years received oral once daily (60 mg, n = 3; 90 11; 120 4)...

603 Background: Datopotamab deruxtecan (Dato-DXd) is an antibody-drug conjugate consisting of a humanized anti-TROP2 IgG1 monoclonal antibody covalently linked to highly potent topoisomerase I inhibitor payload via plasma-stable, tumor-selective, tetrapeptide-based cleavable linker. Dato-DXd has shown encouraging antitumor activity and manageable safety profile in patients (pts) with solid tumors. We report preliminary results pts advanced/metastatic (a/m) urothelial cancer from the ongoing...

We report updated results patients (pts) with locally advanced/metastatic urothelial cancer (la/m UC) from the ongoing phase 1 TROPION-PanTumor01 study (NCT03401385). Methods: Pts unresectable la/m UC (stage III/IV) treated ≥1 prior line of therapy, including an immune checkpoint inhibitor, received 6 mg/kg Q3W. Primary objectives were safety and tolerability. Secondary...

2004 Background: WHO grade II/III gliomas frequently harbor isocitrate dehydrogenase 1 ( IDH1) mutations, resulting in intratumoral accumulation of oncometabolite 2-hydroxyglutarate (2-HG) and subsequent clonal expansion. DS-1001b is an oral selective inhibitor mutant IDH1 R132X that was designed to penetrate the blood-brain barrier. Methods: In this first-in-human, multicenter, phase I study (NCT03030066), eligible patients (pts) with recurrent/progressive glioma received twice daily (bid),...

Abstract Background Axicabtagene ciloleucel (axi-cel) is an autologous chimeric antigen receptor T-cell based anti-CD19 therapy. The ZUMA-1 study, multicenter, single-arm, registrational Phase 1/2 study of axi-cel demonstrated high objective response rate in patients with relapsed/refractory large B-cell lymphoma. Here, we present the results bridging to evaluate efficacy and safety Japanese (JapicCTI-183914). Methods This was phase 2, open-label, single-arm trial. Following leukapheresis,...

Long-term survival in patients with acute myeloid leukemia (AML) remains low, and current treatment modalities are inadequate. Milademetan (DS-3032, RAIN-32), a small-molecule specific murine double minute 2 inhibitor, has shown p53 status-dependent antitumor effect vitro studies. This is the first phase I study report of milademetan monotherapy relapsed/refractory (R/R) AML evaluating safety, tolerability, pharmacokinetics, preliminary tumor response for further clinical development....

Background: In Japan, there are limited options for switching opioid analgesics. Hydromorphone is an analgesic that routinely used instead of morphine cancer pain; however, it not yet available in Japan. The aim this study was to assess the efficacy and safety hydromorphone (DS-7113b) extended-release tablets opioid-naïve patients with pain relieved by non-opioid Subjects methods: This a multicenter, randomized, double-blind, parallel-group trial. A double-dummy method blinding. Each...

Summary Recommended phase 2 doses for some drugs may differ according to a patient's clinical or genetic characteristics. We develop new method that determines the individualized optimal dose patterns of patient covariates and selects are associated with efficacy toxicity in early trials evaluating multiple interest. To address difficulty high dimensional estimation model parameters limited sample size, we propose use Bayesian least absolute shrinkage selection operator, which is penalized...

Here, we developed a new dose-finding method that partitions cohort of patients based on the number dose combinations within prespecified acceptable toxicity range in two-agent combination Phase I trials. In proposed method, same are partitioned according to several combinations, although most existing methods allocate single-dose combination. We compared operating characteristics and through simulation studies.
