Safety, Pharmacokinetics (PK), and Efficacy of ONC 841 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 chemotherapy-associated peripheral neuropathy (motor or sensory) or alopecia. Patients with ongoing and adequately controlled endocrine immune-related AEs are considered stable and eligible for enrollment.

The washout period for cancer therapeutic drugs should be 5 half-life or 21 days for chemotherapy, whichever is shorter; 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. Best supportive care, such as thyroxine, insulin, steroid replacement treatment, blood transfusion 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.
