This is a Phase 1/2, multi-center, open-label study designed to evaluate the safety and efficacy of LOXO-195 when administered orally to patients with NTRK fusion cancers treated with prior TRK inhibition or non-fusion NTRK altered cancers regardless of prior kinase inhibitor treatment.

Best overall response of confirmed PR or CR using RECIST v1.1 or RANO criteria as appropriate in patients with non-fusion NTRK altered cancers who have demonstration of progression following or during receipt of previous anticancer therapy [ Time Frame: Approximately every 8 weeks for one year, then every 12 weeks while on treatment, and every 12 weeks after the last dose (for up to 2 years) in patients who have not progressed ]
For Phase 2

Best overall response of confirmed PR or CR using RECIST v1.1 or RANO criteria as appropriate in patients with documented NTRK alterations, including TRK fusions, who discontinued previous anticancer therapy including TRK inhibitors due to intolerance [ Time Frame: Approximately every 8 weeks for one year, then every 12 weeks while on treatment, and every 12 weeks after the last dose (for up to 2 years) in patients who have not progressed ]

Arms Assigned Interventions
Experimental: LOXO-195
Phase 1- Dose Escalation and determination of MTD; Multiple dose levels of LOXO-195 to be evaluated Phase 2 – Treatment with LOXO-195 at the recommended dose from Phase 1 identified for further study
Drug: LOXO-195
Oral LOXO-195

Detailed Description:
The trial will be conducted in 2 parts: dose escalation (Phase I ) and dose expansion (Phase 2) . During Phase 1, patients with advanced solid tumors are eligible if the tumor has progressed following or has not adequately responded to standard therapy, or if the patient is intolerant of, or unlikely to benefit from or refuses standard therapy. Prior TRK inhibitor therapy is required for patients harboring an NTRK fusion. During Phase 2, the same patient population as designated for Phase 1 will be treated with the dose of LOXO-195 which has been identified during phase 1 to assess specified endpoints.
Eligibility

Ages Eligible for Study: 18 Years and older (Adult, Senior)
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Criteria
Key Inclusion Criteria:

Advanced solid tumor for which, in the opinion of the Investigator, no other standard or investigational therapy offers greater benefit.
A solid tumor diagnosis in the setting of:

a documented NTRK fusion and a clinical history of relapse following a response to a prior TRK inhibitor
a documented NTRK fusion unresponsive to a prior TRK inhibitor
a documented NTRK fusion and a clinical history of intolerance to a prior TRK inhibitor
a documented NTRK alteration other than a fusion, whether or not treated with a prior TRK inhibitor
Patients will be identified via a CLIA certified (or equivalent) laboratory
Performance Status: Eastern Cooperative Oncology Group (ECOG) score ≤ 3. If enrolled with primary CNS tumor to be assessed by RANO, Karnofsky Performance Status (KPS) ≥ 50%
Life expectancy > 4 weeks
Adequate hematologic, hepatic and renal function.
Patients with stable CNS primary tumor, brain metastases, or treated spinal cord compression are eligible if neurological symptoms and steroid use (if applicable) have been stable for 7 days prior to the first dose of LOXO-195
Ability to receive study drug therapy orally
Key Exclusion Criteria:

Required treatment with certain strong CYP3A4 inhibitors or inducers.
Clinically significant active cardiovascular disease or history of myocardial infarction within 6 months prior to planned start of LOXO-195 or prolongation of the QT interval corrected (QTcF) > 480 msec.
Major surgery within 7 days of enrollment
Uncontrolled systemic bacterial, fungal or viral infection
Untreated/symptomatic leptomeningeal carcinomatosis, spinal cord compression, primary CNS metastases or primary CNS malignancy.
Pregnancy or lactation.
