Brief summary
The purpose of this research study is to determine the safety and tolerability of TL-895. There are 2 parts of this study. Part 1 tested increasing doses of TL-895 to identify the recommended safe dose for participants with relapsed/refractory (R/R) B cell malignancies who failed at least 1 but no more than 3 prior therapies. Part 1 of this study is no longer enrolling participants. Arms 1 & 2 of Part 2 of this study will test different doses of TL-895 in participants with R/R CLL or SLL who have failed at least 1 prior therapy. Arms 1 & 2 of Part 2 of this study is randomized (like the flip of a coin) to receive a specific treatment dose. If someone participates in arms 1 or 2 of Part 2, the dose they receive will be either 100mg twice a day or 150mg twice a day. Arms 3 and 4 of Part 2 of this study will test the 150mg and 100mg BID dose of TL-895, respectively in treatment naïve participants with CLL/SLL. Arms 5 and 6 of Part 2 will test 150mg TL-895 BID in combination with 240 mg navtemadlin QD in participants with relapsed/refractory and treatment naïve without 17p(del). Arm 7 will test 150mg TL-895 in combination with 240 mg navtemadlin QD in participants with relapsed/refractory CLL/SLL with 17p(del). Every participant in this study will receive TL-895.
Interventions
TL-895 is an experimental tyrosine kinase inhibitor anticancer drug taken by mouth.
Navtemadlin is an experimental MDM2 anticancer drug taken by mouth.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Part 1 (Dose Escalation): DLTs (Dose Limiting Toxicities) during Cycle 1 | Baseline up to the end of cycle 1 (28 days) | DLT is defined as any of the adverse event (AEs) of a certain grade or above, related to drug. |
| Part 2 (Dose Expansion): Overall Response Rate (ORR) | Baseline up to end of study (2 years after last patient enrolled) | The proportion of subjects achieving CR, CRi, nodular partial response (nPR), partial response (PR), or PR with lymphocytosis (PR-L) at any time while on the study based on iwCLL response criteria (2), as assessed by investigators |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Part 2: Duration of Clinical Response (DOR) | Baseline up to end of study (2 years after last patient enrolled) | Time from initial response to disease progression or death from any cause |
| Part 1 (Dose Escalation): Best Overall Response (BOR)/Progression Free Survival (PFS) | Baseline up to 6 months on treatment | Defined by the length of time during the treatment of the disease, that a participant lives with the disease but it does not get worse based on investigator assessments |
| Part 2: Assessment of Safety and Tolerability via Clinical Measurements | Baseline up to end of study (2 years after last patient enrolled) | Assessments including but not limited to clinical laboratory measurements, ECGs, vital signs, and ECOG performance |
| Part 2: Number of Participants with Treatment-Emergent Adverse Events (TEAEs) | Baseline up to end of study (2 years after last patient enrolled) | Incidence, nature, severity of treatment-emergent adverse events (TEAEs), and deaths, including cause of death, from screening up to the end of study visit of participants with CLL/SLL who have failed at least 1 line of therapy |
| Part 2 (Dose Expansion): Overall CR/CRi rate | Baseline up to end of study (2 years after last patient enrolled) | The proportion of subjects achieving CR/CRi based on iwCLL response criteria |
