A Phase 1/2 Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of TERN-701 in Participants With Chronic Myeloid Leukemia (CARDINAL)
(CARDINAL)
What this study is about
The goal of the study is to evaluate the safety, tolerability, how the drug moves through the body, how the drug affects the body and effectiveness of TERN-701, a highly selective allosteric inhibitor of BCR-ABL1, in participants with previously treated chronic phase - chronic myeloid leukemia (CP-CML).
View original scientific description
The goal of the study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of TERN-701, a highly selective allosteric inhibitor of BCR-ABL1, in participants with previously treated chronic phase - chronic myeloid leukemia (CP-CML). The study has two parts: Part 1 of the trial (Dose Escalation) will evaluate sequential dose escalation cohorts of TERN-701 administered once daily. Part 2 (Dose Expansion) consists of randomized, parallel dose expansion cohorts of TERN-701 that will further evaluate the efficacy and safety of 2 recommended dose levels for expansion selected from Part 1. Part 2m (mutation cohort) will further evaluate the efficacy and safety of 500mg of TERN-701 in previously treated CP-CML participants with certain resistance mutations. In both Part 1 and Part 2, participants will receive continuous once daily dosing of TERN-701 divided into 28-day cycles. During the treatment period, participants will have scheduled visits to the trial center at Cycle 1 day 1(C1D1), C1D2 (Part 1 only), C1D8, C1D15, and C1D16 (Part 1 only), followed by Day 1 of Cycles 2 through 7, and Day 1 of every 3 cycles thereafter. Approximately 180 participants could be enrolled in this trial, up to 80 participants in Part 1 (dose escalation), including optional backfill cohorts, approximately 80 participants in Part 2 (randomized dose expansion), and approximately 20 participants in Part 2m (mutation cohort). All participants will receive active trial intervention. Four dose-level cohorts have been evaluated in Part 1; two dose levels will be evaluated in Part 2 (Randomized Dose Expansion), and one dose level will be evaluated in Part 2m (mutation cohort).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
