Safety, Pharmacokinetics (PK), and Efficacy of ONC-783 in Advanced Solid Tumors

Patients who have not recovered to NCI CTCAE Grade ≤ 1 from an adverse event (AE) due to cancer therapeutics except the Grade ≤ 2 chemotherapy-associated peripheral neuropathy (motor or sensory) or alopecia. Patients with ongoing and adequately controlled Grade ≤ 2 endocrine immune-related AEs are considered stable and eligible for enrollment.

The washout period for cancer therapeutic drugs (such as chemotherapy, radiation or targeted therapy) is 21 days or 28 days for monoclonal antibody therapy. Palliative radiotherapy for painful metastases or metastases in potentially sensitive locations (e.g., epidural space) ≥ 7 days prior to the first dose of study drug is allowed. Best supportive care, such as thyroxine, insulin, steroid replacement treatment, growth factors and therapy for non-cancer conditions are allowed.

Patients who are currently enrolled in any other clinical trial testing an investigational agent or device, or with concurrent anticancer treatment (except palliative bone-directed radiotherapy), immune therapy, or cytokine therapy or anticipated to require another antineoplastic therapy during the study.

Patients who are on chronic systemic steroid therapy at doses higher than 10 mg/day prednisone or equivalent within 7 days before first treatment.
