Inclusion criteria
* Advanced solid tumor * Measurable disease, per RECIST v1.1 * Eastern Cooperative Oncology Group (ECOG) performance status 0-1 * Adequate organ function
Exclusion criteria
* Has not recovered \[recovery is defined as NCI CTCAE, version 5.0, grade ≤1\] from the acute toxicities of previous therapy, except treatment-related alopecia or laboratory abnormalities otherwise meeting eligibility requirements * Received prior chemotherapeutic, investigational, or other therapies for the treatment of cancer within 14 days with small molecule and within 28 days with biologic before the first dose of TORL-3-600 * Progressive or symptomatic brain metastases * Serious, uncontrolled medical disorder, nonmalignant systemic disease, or active, uncontrolled infection * History of significant cardiac disease * History of myelodysplastic syndrome (MDS) or AML * History of another cancer within 3 years before Day 1 of study treatment, with the exception of basal or squamous cell carcinoma of the skin that has been definitively treated. A history of other malignancies with a low risk of recurrence, including appropriately treated ductal carcinoma in situ (DCIS) of the breast and prostate cancer with a Gleason score less than or equal to 6, are also not excluded * If female, is pregnant or breastfeeding
