A Study of Varlilumab (Anti-CD27) and Ipilimumab and CDX-1401 in Patients With Unresectable Stage III or IV Melanoma
- Conditions
- Unresectable Stage III or Stage IV Melanoma
- Interventions
- Drug: Combination of varlilumab and ipilimumab
- Registration Number
- NCT02413827
- Lead Sponsor
- Celldex Therapeutics
- Brief Summary
This is a study to determine the clinical benefit (how well the drug works), safety and tolerability of combining a) varlilumab and ipilimumab and b) varlilumab, ipilimumab, CDX-1401 and poly-ICLC. The study will enroll patients with unresectable Stage III or Stage IV melanoma.
- Detailed Description
Varlilumab is a fully human monoclonal antibody that binds to a molecule called CD27 found on certain immune cells and may act to promote anti-tumor effects.
Yervoyโข (Ipilimumab) is a human monoclonal antibody that blocks CTLA-4, a protein receptor that downregulates the immune system.
CDX-1401 is a vaccine made of a fully human monoclonal antibody linked to NY-ESO-1 and is designed to deliver NY-ESO-1 to professional antigen presenting cells for generating robust immune responses against cancer cells expressing NY-ESO-1. CDX-1401 is administered with poly-ICLC, an adjuvant that enhances vaccine-induced immune responses.
This study will evaluate the safety, tolerability and efficacy of varlilumab and ipilimumab, with or without the addition of CDX-1401/poly-ICLC, in patients with melanoma.
Eligible patients that enroll in the Phase I portion of the study will be assigned to one of two possible dose levels of varlilumab in combination with 3 mg/kg ipilimumab. The first phase of the study will test the safety profile of the combination and determine which dose of varlilumab will be studied in Phase II of the study.
During Phase II, up to 48 patients whose tumors do not express NY-ESO-1, will receive the recommended dose of varlilumab determined from Phase I with 3 mg/kg ipilimumab. Up to 24 patients whose tumors express NY-ESO-1 will receive the recommended dose of varlilumab combined with 3 mg/kg ipilimumab and 1 mg CDX-1401 along with 2 mg poly-ICLC.
All patients enrolled in the study will be closely monitored to determine if there is a response to the treatment as well as for any side effects that may occur.

- Chemotherapy within 21 days or at least 5 half-lives (whichever is shorter) prior to first dose of study treatment.
- Monoclonal based therapies within 4 weeks and all other immunotherapy within 2 weeks prior to first dose of study treatment.
- Systemic radiation therapy within 4 weeks, focal radiotherapy within 2 weeks and radiopharmaceuticals (strontium, samarium) within 8 weeks prior to first dose of study treatment.
- Ocular Melanoma
- Other prior malignancy, except for adequately treated basal or squamous cell skin cancer or in situ cancers; or any other cancer from which the patient has been disease-free for at least 3 years.
- Active, untreated central nervous system metastases.
- Active autoimmune disease or documented history of autoimmune disease.
- Active diverticulitis
- Significant cardiovascular disease including CHF or poorly controlled hypertension.

Group Intervention Description Phase l: varlilumab and ipilimumab Combination of varlilumab and ipilimumab -
- Primary Outcome Measures
Name Time Method Phase l: Safety and tolerability of varlilumab in combination with ipilimumab as measured by incidences of drug related adverse events (AEs), serious drug related AEs, dose-limiting toxicities and laboratory test abnormalities. Safety follow-up is 70 days from last study drug dose. Phase ll: The objective response rate (ORR) is defined as the proportion of patients who achieve radiographic partial or complete response (PR or CR) according to the mWHO tumor response criteria. Up to 24 weeks
