Description

Summary

Phase II, multi-center, open-label study of patients with advanced solid tumors harboring a fusion of NTRK1, NTRK2 or NTRK3.

Official Title

A Phase II Basket Study of the Oral TRK Inhibitor LOXO-101 (Larotrectinib) in Subjects With NTRK Fusion-Positive Tumors

Details

This is a Phase II, multi-center, open-label study of patients with advanced solid tumors harboring a fusion of NTRK1, NTRK2 or NTRK3. Patients with NTRK1, NTRK2 or NTRK3 fusion-positive cancers will be identified through molecular assay.

Larotrectinib (LOXO-101) will be administered orally at 100mg twice daily (BID), with each cycle consisting of 28 days of dosing administered on a continuous basis.

The study will analyze 9 cohorts of patients with tumors bearing NTRK fusions, including non small cell lung cancer, thyroid cancer, sarcoma, colorectal cancer, salivary gland cancer, biliary cancer and primary CNS tumor, as well as a cohort that will enroll patients not included in the histologies listed above. Cohort 9 will include patients who meet criteria for Cohorts 1 to 8, but with documented NTRK fusion from a laboratory where CLIA or equivalent certification cannot be confirmed by the Sponsor at the time of consent.

Eligibility

For people ages 12 years and up

Key Inclusion Criteria:

  1. Locally-advanced or metastatic malignancy with an NTRK1, NTRK2, or NTRK3 gene fusion,identified through molecular assays as routinely performed at CLIA or other similarly-certified laboratories. Subjects who have NTRK gene fusion identified in a lab where certification of the lab cannot be confirmed by the Sponsor at the time of consent may enroll to Cohort 9.
  2. Subjects must have received prior standard therapy appropriate for their tumor type and stage of disease, or in the opinion of the Investigator, would be unlikely to tolerate or derive clinical benefit from appropriate standard of care therapy.
  3. Adequate organ function as defined by the following criteria:
  4. Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) < 2.5 upper limit of normal (ULN), or AST and ALT < 5 ULN if liver function abnormalities are due to underlying malignancy.
  5. Total bilirubin < 2.5 x ULN, except in the setting of biliary obstruction.Subjects with a known history of Gilberts Disease and an isolated elevation of indirect bilirubin are eligible
  6. Serum creatinine < 2.0 x ULN OR an estimated glomerular filtration rate ≥ 30 mL/minute using the Cockcroft-Gault formula
  7. ECOG score < 3 (age >16 years) or Lansky Performance Score (LPS) >40% (age <16 years). If enrolled with primary CNS tumor to be assessed by RANO, Karnofsky Performance Score (KPS) (age >16 years) or LPS (age <16 years) >50%
  8. Archived tumor tissue. If archival tissue is known to not be available, then an on-study tumor biopsy should be attempted if it can be safely performed.

Key Exclusion Criteria:

  1. Symptomatic or unstable brain metastases. (Note: Subjects with asymptomatic brain metastases are eligible to participate in the study). Subjects with primary CNS tumors are eligible.
  2. Investigational agent or anticancer therapy within 2 weeks prior to the planned start of larotrectinib (LOXO-101) or 5 half-lives, whichever is shorter, and without recovery of clinically significant toxicities from that therapy.
  3. Pregnancy or lactation.
