Clinical trials

BDTX-4933-101 is a first-in-human, open-label, Phase 1/2 dose escalation, dose optimization and expansion study designed to evaluate the safety and tolerability of S241656 as monotherapy and in combination with other anti-cancer therapies in participants with selected advanced malignancies. The study population for the Dose Escalation part of the study comprises adults with recurrent advanced/metastatic non-small cell lung cancer (NSCLC), Gastrointestinal (GI) cancers, and other solid tumors harboring KRAS, HRAS, NRAS, BRAF, and/or CRAF (Rapidly Accelerated Fibrosarcoma (RAF1)) mutations or alterations. A dose optimization part in adults with NSCLC may follow the dose escalation phase if the sponsor, in consultation with the safety review committee, decides it is necessary to further characterize the optimal dose. However, the study may also proceed directly to the expansion phase. The study population for the Dose Expansion part of the study comprises adults with advanced/metastatic NSCLC with KRAS and/or BRAF mutations, and with Pancreatic Ductal AdenoCarcinoma (PDAC), ColoRectal Cancer (CRC), and Biliary Tract Cancer (BTC) with KRAS, HRAS, NRAS, BRAF, and/or CRAF (RAF1) mutations and alterations. All patients will self-administer S241656 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.

The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of AG-120 in advanced hematologic malignancies that harbor an IDH1 mutation. The first portion of the study is a dose escalation phase where cohorts of patients will receive ascending oral doses of AG-120 to determine maximum tolerated dose (MTD) and/or the recommended Phase II dose. The second portion of the study is a dose expansion phase where four cohorts of patients will receive AG-120 to further evaluate the safety, tolerability, and clinical activity of the recommended Phase II dose. Additionally, the study includes a substudy evaluating the safety and tolerability, clinical activity, pharmacokinetics, and pharmacodynamics of AG-120 in subjects with relapsed or refractory myelodysplastic syndrome with an IDH1 mutation. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

Study CL1-230815-001 (KANDLE) is a Phase Ib/II, First In Human, multicentre, open-label, multiple ascending dose study to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamic (PD) effect of S230815 in pediatric participants with KCNT1-related Developmental Epileptic Encephalopathy. To participate in the study, participants must have a diagnosis of Developmental Epileptic Encephalopathy due to a documented pathogenic or likely pathogenic variant in KCNT1 (to be confirmed by central genetic testing at the screening visit). The study consists of a screening period followed by two consecutive interventional parts. Part 1 will evaluate multiple ascending doses of S230815. Part 2 is a long-term treatment extension for participants who have completed Part 1. Participants will seamlessly roll-over from Part 1 to Part 2, resuming the same cohort as they were assigned in Part 1, and will receive S230815 for a maximum of 72 weeks.

The objective of this study is to investigate the safety, tolerability and preliminary activity of ivosidenib in combination with durvalumab and gemcitabine/cisplatin as first-line therapy in participants with locally advanced, unresectable or metastatic cholangiocarcinoma with an IDH1 mutation. The study will begin with a safety lead-in phase (Phase 1b study) to determine the recommended combination dose (RDC) and then will transition to an expansion phase (Phase 2 study) to assess the clinical activity of ivosidenib in combination with durvalumab and gemcitabine/cisplatin at the RCD. During the treatment period participants will have study visits on days 1, 8, and 15 of Cycle 1, on days 1 and 8 of Cycle 2 to 8, and on day 1 of each additional cycle. Cycles 1 through 8 are 21 day cycles, and each following cycle is 28 days. Approximately 30 days and 90 days after treatment has ended, safety follow-up visits will occur and then participants will be followed for survival every 3 months. Study visits may include blood tests, ECG, vital signs, and a physical examination.

This study will enroll participants with myelodysplastic syndromes (MDS) with an Isocitrate dehydrogenase protein, 1 (IDH1) mutation, who have not received treatment with a hypomethylating agent previously. Participants will be randomized to receive either ivosidenib (IVO) alone or azacitidine (AZA) alone. IVO will be administered daily throughout the 28-day treatment cycle and AZA will be administered for the first 7 days of each 28-day cycle. Study visits will be conducted every week during Cycle 1 (Days 1, 8, 15, and 22), and Day 1 of each cycle thereafter. After the last dose of treatment, participants will attend an safety follow-up visit and participants will be followed to assess overall survival. Study visits may include a bone marrow aspirate, physical exam, echocardiogram (ECHO), electrocardiogram (ECG), blood and urine analysis, and questionnaires.
