Brief summary

This is a phase 1b/2 study to evaluate the safety and efficacy of metronomic combination therapy in subjects with melanoma who have progressed on or after chemotherapy and anti-PD-1/PD-L1 therapy.

Detailed description

Treatment will be administered in two phases. Subjects will continue treatment for up to 1 year or until they experience progressive disease (PD) or experience unacceptable toxicity (not correctable with dose reduction), withdraw consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. Those who have a complete response (CR) in the induction phase will enter phase 2 of the study. Subjects may remain on phase 2 of the study for up to 1 year. Treatment will continue in phase 2 until the subject experiences PD or unacceptable toxicity (not correctable with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. The maximum time on study treatment, including both phases, is up to 2 years.

Inclusion criteria

1. Age ≥ 18 years. 2. Able to understand and provide a signed informed consent that fulfills the relevant IRB or IEC guidelines. 3. Histologically-confirmed metastatic or unresectable melanoma with progression on or after chemotherapy and anti-PD-1/PD-L1 therapy. 4. ECOG performance status of 0 to 2. 5. Have at least 1 measurable lesion of ≥ 1.5 cm. 6. Must have a recent tumor biopsy specimen obtained following the conclusion of the most recent anti-cancer treatment. If a historic specimen is not available, the subject must be willing to undergo a biopsy during the screening period. 7. Must be willing to provide blood samples for exploratory analyses, and, if considered safe by the Investigator, a tumor biopsy specimen at 8 weeks after the start of treatment. 8. Ability to attend required study visits and return for adequate follow-up, as required by this protocol. 9. Agreement to practice effective contraception for female subjects of child-bearing potential and non-sterile males. Female subjects of child-bearing potential must agree to use effective contraception for up to 1 year after completion of therapy, and non-sterile male subjects must agree to use a condom for up to 4 months after treatment.

Exclusion criteria

1. History of persistent grade 2 or higher (CTCAE Version 4.03) hematologic toxicity resulting from previous therapy. 2. History of other active malignancies or brain metastasis except: controlled basal cell carcinoma; prior history of prostate cancer that is not under active systemic treatment (except hormonal therapy) and with undetectable PSA (\< 0.2 ng/mL); bulky (≥ 1.5 cm) disease with metastasis in the central hilar area of the chest and involving the pulmonary vasculature. Subjects with a history of another malignancy must have \> 5 years without evidence of disease. 3. Serious uncontrolled concomitant disease that would contraindicate the use of the investigational drug used in this study or that would put the subject at high risk for treatment-related complications. 4. Systemic autoimmune disease (eg, lupus erythematosus, rheumatoid arthritis, Addison's disease, autoimmune disease associated with lymphoma). 5. History of organ transplant requiring immunosuppression. 6. History of or active inflammatory bowel disease (eg, Crohn's disease, ulcerative colitis). 7. Requires whole blood transfusion to meet eligibility criteria. 8. Inadequate organ function, evidenced by the following laboratory results: 1. WBC count \< 3,500 cells/mm3. 2. Absolute neutrophil count \< 1,500 cells/mm3. 3. Platelet count \< 100,000 cells/mm3. 4. Hemoglobin \< 9 g/dL. 5. Total bilirubin greater than the ULN (unless the subject has documented Gilbert's syndrome). 6. AST (SGOT)) or ALT (SGPT) \> 2.5 × ULN (\> 5 × ULN in subjects with liver metastases). 7. Alkaline phosphatase levels \> 2.5 × ULN (\> 5 × ULN in subjects with liver metastases, or \>10 × ULN in subjects with bone metastases). 8. Serum creatinine \> 2.0 mg/dL or 177 μmol/L. 9. INR or aPTT or PTT \>1.5 × ULN (unless on therapeutic anti-coagulation). 9.

Dyspnea at rest due to complications of advanced malignancy or other disease requiring continuous oxygen therapy. 11. Positive results of screening test for HIV, HBV, or HCV. 12. Current chronic daily treatment (continuous for \> 3 months) with systemic corticosteroids (dose equivalent to or greater than 10 mg/day methylprednisolone), excluding inhaled steroids. Short-term steroid use to prevent IV contrast allergic reaction or anaphylaxis in subjects who have known contrast allergies is allowed. 13. Known hypersensitivity to any component of the study medication(s). 14. Subjects taking any medication(s) (herbal or prescribed) known to have an adverse drug reaction with any of the study medications. 15.

Concurrent or prior use of a strong CYP2C8 inhibitor (gemfibrozil) or moderate CYP2C8 inducer (rifampin) within 14 days before study day 1. 17.
