TT-01488

Caixia Sun, PhD

Nitin Jain, MD

This is a first-in-human (FIH), multicenter, open-label Phase I dose escalation study to evaluate the safety and preliminary efficacy of the TT-01488 tablet, a non-covalent reversible BTK inhibitor, for the treatment of adult patients with B-cell malignancies.

The study will consist of two parts, dose escalation and dose expansion. A modified 3+3 design will be used to guide the dose escalation and the determination of the dose recommended for dose expansion (DRDE). A sentinel cohort comprising of one subject will be enrolled at a starting dose of 50 mg q.d. Subsequently, patients will be enrolled according to the standard 3+3 dose escalation design to determine the DRDE. Once the DRDE has been selected, TT-01488 of DRDE will be further tested in the dose expansion cohort to verify the safety and preliminary efficacy as observed in the dose escalation cohorts. A recommended Phase II dose (RP2D) may be determined based on the totality of safety, pharmacokinetics, and efficacy data from the dose escalation cohorts and dose expansion cohort.

This is an open-label, multi-center Phase 1/2 study of oral LOXO-305 (pirtobrutinib) in patients with CLL/SLL and NHL who have failed or are intolerant to standard of care.

This study includes 3 parts: Phase 1 (pirtobrutinib monotherapy dose escalation and dose expansion), Phase 1b (pirtobrutinib combination therapy dose expansion), and Phase 2 (pirtobrutinib monotherapy dose expansion). In Phase 1, patients will be enrolled using an accelerated titration design. The starting dose of pirtobrutinib in oral tablet form is 25 mg/day (e.g., 25 mg once daily \[QD\]). Once the MTD and/or RP2D is identified in Phase 1 dose escalation, enrollment will continue to Phase 1 dose expansion and can commence to Phase 1b (Arms A and B). For Phase 2, patients will be enrolled to one of seven Phase 2 dose expansion cohorts depending on tumor histology and prior treatment history. Cycle length will be 28 days.

EORTC physical function item scores range from 1 (not at all) to 4 (very much) with higher scores indicating poorer functioning.The total EORTC physical functioning score ranges from 0-100 where a higher score indicates higher/healthier level of functioning.

Medical Director

This study aims to evaluate the safety, tolerability, pharmacodynamic, and pharmacokinetic (PK) of nemtabrutinib (formerly ARQ 531) tablets in selected participants with relapsed or refractory hematologic malignancies. No formal hypothesis testing will be performed for this study.

This study includes 2 parts: Phase 1 (dose escalation) and Phase 2 (dose expansion). In Phase 1, participants will enroll using 3+3 dose escalation design. The starting dose of nemtabrutinib in oral tablet form was 5mg/day continuously. Dose escalation will continue until the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and dosing schedule is reached based on protocol-defined dose limiting toxicity (DLT). After the determination of the RP2D, 9 expansion cohorts will be initiated to evaluate the safety, tolerability, and efficacy of nemtabrutinib at RP2D in participants with specifically defined disease.

DLT is defined by the occurrence of any of the following treatment emergent adverse event (TEAE) unless unequivocally due to the underlying malignancy or an extraneous cause within the first 28 days of study treatment (for dose escalation only) and graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. Any Grade 5 TEAE, any Grade 3 nonhematological TEAE except alopecia, nausea, vomiting, diarrhea, and transient Grade 3 laboratory abnormalities which recover within 1 week without intervention, any Grade 3 hematological TEAE that does not recover to Grade 1 or baseline within 7 days with the exception of Grade 3 lymphocytosis, which is considered to be an expected outcome of BTK inhibition, any Grade 4 nonhematological and hematological TEAE, or any other toxicity that in the view of the investigator represents a clinically significant hazard to the participant.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experienced an AE will be reported.
