Precision drug shows promise for rare Gene-Driven cancers
NCT ID NCT06390852
First seen Jun 27, 2026 · Last updated Sep 02, 2026 · Updated 4 times
Summary
This study tests a drug called larotrectinib in 35 adults with advanced cancers (including lymphoma and solid tumors) that have a specific NTRK gene fusion. The drug blocks a faulty protein that tells cancer cells to grow, aiming to shrink tumors or stop them from spreading. Participants take the drug in cycles and are monitored for response every few weeks.

Inclusion Criteria: * Patients must have met applicable eligibility criteria in the Master MATCH Protocol EAY131/ NCI-2015-00054 prior to registration to treatment subprotocol * Patients must fulfill all eligibility criteria of MATCH Master Protocol at the time of registration to treatment step (Step 1, 3, 5, 7) * Patients must have a malignancy harboring an NTRK1, NTRK2 or NTRK3 gene fusion, as determined by the MATCH screening assessment * Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have no clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block) * Patients must not have known hypersensitivity to larotrectinib (LOXO-101) or compounds of similar chemical or biologic composition * Patients with inability to discontinue treatment with a strong CYP3A4 inhibitor or inducer prior to start of treatment are excluded * Patients who have previously received treatment with a TRKA, TRKB, or TRKC inhibitor are excluded. Such inhibitors include larotrectinib (LOXO-101), entrectinib (RXDX-101), TSR-011, DS6051, altiratinib (DCC-2701), MGCD516, dovitinib (TKI258, CHIR528), AZD7451, PLX7486, and BIBF1120
