Brief summary

This Phase I dose escalation study will evaluate Procaspase Activating Compound-1 (PAC-1), a small molecule that activates procaspase -3 to caspase-3, resulting in apoptosis of cancer cells, in patients with advanced malignancies. As of March 1, 2019, only patients with neuroendocrine tumors will be enrolled in Component 1 of this study. PAC-1 is taken orally on days 1-21 of a 28-day cycle. The maximum tolerated dose (MTD) of PAC-1 (5 dose levels) will be determined using a modified-Fibonacci dose-escalation 3+3 design. Treatment continues until disease progression, unacceptable toxicity, physician discretion, or patient refusal.

Inclusion criteria

1. Male or female ≥ 18 years of age 2. Diagnosis of advanced solid tumor or hematologic malignancy (limited to lymphoma) that has failed or become intolerant to standard therapy 3. Has measurable disease, defined as at least 1 tumor that fulfills the criteria for a target lesion according to RECIST 1.1, or lymphoma that fulfills the Deauville PET Criteria 4. Has an ECOG PS of 0, 1, or 2 5. Has total bilirubin \< 1.5 mg/dL, serum albumin \> 3.0 gm/dL, AST and ALT \< 1.5 ULN or \< 3 x ULN for subjects with known hepatic metastases 6. Has serum creatinine \< 1.5 × ULN 7. Has hemoglobin ≥ 10 g/dL, ANC ≥ 1.5 × 109/L, and platelet count ≥ 100 × 109/L 8. Must be able to take oral medication and to maintain a fast as required for 2 hours before and 1 hour after capsule(s) administration 9. Must be willing and able to comply with study 10. Has read, understood, and signed the ICF 11. Women of childbearing potential must not be pregnant or breast-feeding. In addition, a medically acceptable method of birth control must be used or total abstinence. Women who are postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) are not considered to be WOCP 12. Men who are not surgically or medically sterile must agree to use an acceptable method of contraception. Male patients with female sexual partners who are pregnant, possibly pregnant, or who could become pregnant during the study must agree to use condoms at least one month after the last dose of study drug. Total abstinence for the same study period is an acceptable alternative 13. Prior systemic treatments for metastatic disease are permitted but may not be ongoing, including targeted therapies, biologic response modifiers, chemotherapy, hormonal therapy, or investigational therapy 14. Willingness to donate blood for biomarker studies related to the type of therapies used in this trial and the tumor types being treated

Exclusion criteria

1. Had surgery within 4 weeks prior to study treatment except for minor procedures (hepatic biliary stent placement is allowed) 2. Gliomas are excluded, as well as any history of brain metastases, seizures or underlying brain injury 3. May not have received cytotoxic chemotherapy, targeted therapies, biologic response modifiers, chemotherapy, and hormonal therapy within the last 3 weeks, or nitrosureas within the last 6 weeks prior to study treatment. 4. Has a history of blood clots, pulmonary embolism, or DVT unless controlled by anticoagulant treatment 5. Has a history of an arterial thromboembolic event within the prior six months including CVA, TIA, MI, or unstable angina 6. Has uncontrolled HIV or hepatitis B or C 7. Has any clinically significant infection 8. Has any other severe, uncontrolled medical condition, including uncontrolled DM or unstable CHF 9. Radiation therapy to more than 25% of the bone marrow 10. Prior allogeneic bone marrow or organ transplantation 11. \> Grade 1 peripheral neuropathy within 14 days before enrollment. 12. Patient has received other investigational drugs with 14 days before enrollment 13. Other severe acute or chronic medical or psychiatric conditions or laboratory abnormality that may increase the risk associated with study participation 14. Abnormalities on 12-lead electrocardiogram (ECG) considered by the investigator to be clinically significant (such as acute ischemia, left bundle branch block, ventricular arrhythmias) or baseline prolongation of the rate-corrected QT interval (e.g., repeated demonstration of QTc interval \> 480 milliseconds) 15. Presence of any non-healing wound, fracture, or ulcer 16. Has any condition that, in the opinion of the investigator, might jeopardize the safety of the patient or interfere with protocol compliance 17. Has any mental or medical condition that prevents the patient from giving informed consent

Design outcomes

Primary

MeasureTime frameDescription
Maximum Tolerated DoseUp to 30 days post last doseThe primary objective of this study component is to determine the maximum tolerated dose (MTD) of PAC-1 in patients with advanced, previously treated malignancy, by evaluation of toxicity and tolerability.

Secondary

MeasureTime frameDescription
Adverse EffectsUp to 30 days post final doseCharacterize adverse effects (AE) of PAC-1 in patients with advanced malignancy.
Disease Response based on RECIST Criteria for patients with solid tumorsUp to 8 weeks following final doseEvaluate clinical response of PAC-1 in patients with solid tumors (RECIST v 1.1).
Disease Response based on Deauville PET Criteria for patients with lymphomaUp to 8 weeks following final doseEvaluate clinical response of PAC-1 in patients with lymphoma (Deauville PET Criteria).
