• Locally-advanced or metastatic malignancy with an NTRK1, NTRK2, or NTRK3 gene fusion, identified through molecular assays as routinely performed at Clinical Laboratory Improvement Amendments (CLIA) or other similarly-certified laboratories. Subjects who have an NTRK gene fusion identified in a lab where CLIA or equivalent certification cannot be confirmed by the Sponsor at the time of consent may have been enrolled in Cohort 9 as per protocol versions 1.0 - 8.0. From protocol version 9.0: CLIA or similar certification of the lab performing the fusion assay is required. However, patients may be included after discussion with the sponsor if the lab performing the fusion assay is not CLIA or similar certified.
• Capable of giving signed informed consent as described in protocol which includes compliance with the requirements, restrictions listed in the informed consent form (ICF), and in this protocol.
• " For subjects eligible for enrollment to bone health cohort only: life expectancy of at least 6 months, based on investigator assessment."
• Subjects who have received prior standard therapy appropriate for their tumor type and stage of disease, or who have no satisfactory alternative treatments and in the opinion of the Investigator, would be unlikely to tolerate or derive clinically meaningful benefit from appropriate standard of care therapy.
• "Subjects must have at least one measurable lesion as defined by RECIST v1.1 (Eisenhauer et al. 2009). Subjects with solid tumors without RECIST v1.1 measurable disease (e.g., evaluable disease only) had been eligible for enrollment to Cohort 8 as per protocol versions 1.0 - 8.0, regardless of tumor type. Subjects with primary central nervous system (CNS) tumors should meet the following criteria: a. Have received prior treatment including radiation and/or chemotherapy, with radiation completed > 12 weeks prior to C1D1 of therapy, as recommended or appropriate for that CNS tumor type. b. Have ≥ 1 site of bi-dimensionally measurable disease (confirmed by magnetic resonance imaging [MRI] and evaluable by RANO criteria), with the size of at least one of the measurable lesions ≥ 1 cm in each dimension and noted on more than one imaging slice. c. Imaging study performed within 28 days before enrollment. If on steroid therapy, the dose must be stable for at least 7 days immediately before and during the imaging study. d. Must be neurologically stable based on stable neurologic exam for 7 days prior to enrollment. For subjects eligible for enrollment to bone health cohort, inclusion criterion 3 is modified as the following: e. Subjects must have at least one lesion at baseline (measurable or non-measurable as defined by RECIST v1.1 or RANO criteria, as appropriate to tumor type). f. Subjects with primary CNS tumors must be neurologically stable based on stable neurologic exam for 7 days prior to enrollment."
