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.

If on steroid therapy, the dose must be stable for at least 7 days immediately before and during the imaging study.</li><li>Must be neurologically stable based on stable neurologic exam for 7 days prior to enrollment.</li></ol></li><li>Performance Status: Eastern Cooperative Oncology Group (ECOG) score ≤ 3 If enrolled with primary CNS tumor to be assessed by RANO, Karnofsky Performance Score (KPS) ≥50%</li><li>Tumor tissue before treatment (mandatory).
If neither fresh tissue can be obtained nor archival tissue is available patients might be enrolled after consultation with the sponsor.</li><li>Willingness of men and women of reproductive potential to use double effective birth control methods, defined as one used by the subject and another by his&#x2F;her partner, for the duration of treatment and for 1 month following study completion.</li></ul><p>Exclusion Criteria:</p><ul><li>Prior progression while receiving approved or investigational tyrosine kinase inhibitors targeting tropomyosin receptor kinase (TRK).
Subjects who received less than 28 days of treatment and discontinued because of intolerance or toxicity are eligible.</li><li>Symptomatic or unstable brain metastases.
(Note: Subjects with asymptomatic brain metastases are eligible to participate in the study.)
Subjects with primary central nervous system (CNS) tumors are eligible.</li><li>Pregnancy or lactation.</li><li>Active uncontrolled systemic bacterial, viral, or fungal infection Common Terminology Criteria for Adverse Events(CTCAE) grade ≥ 2; unstable cardiovascular disease, or other systemic disease that would limit compliance with study procedures.</li><li><p>Unstable cardiovascular disease is defined as:</p><ul><li>In adults, persistently uncontrolled hypertension defined as systolic blood pressure (BP) &gt; 150 mmHg and&#x2F;or diastolic BP &gt; 100 mmHg despite antihypertensive therapy.</li><li>Myocardial infarction within 3 months of screening.</li><li>Stroke within 3 months of screening.</li></ul></li></ul>
