Melanoma Clinical Trial
Polarized Dendritic Cell (aDC1) Based Treatment, Interferon Alpha-2, Rintatolimod, and Celecoxib for the Treatment of HLA-A2+ Refractory Melanoma
Summary
This phase II trial studies how well polarized dendritic cell (aDC1) vaccine, interferon alpha-2, rintatolimod, and celecoxib work together in treating patients with HLA-A2 positive (+) melanoma that has not responded to previous treatment (refractory). The aDC1 vaccine contains white blood cells (dendritic cells or DCs) that stimulates the immune system. Interferon alpha-2 can improve the body?s natural response to infections and other diseases. It can also interfere with the division of cancer cells and slow tumor growth. Rintalolimid may stimulate the immune system. Celecoxib is a drug that reduces pain. This study is being done to find out if aDC1 vaccine, interferon alpha-2, rintatolimod, and celecoxib can prevent the growth and/or progression of melanoma.
Full Description
PRIMARY OBJECTIVE:
I. To evaluate the objective response rate to treatment with an autologous alpha-type-1 polarized dendritic cells (alphaDC1)/TBVA cell-based treatment (alpha-type-1-polarized dendritic cells loaded with tumor blood vessel-targeting antigenic peptides) plus cytokine modulating (CKM) regimen (rintatolimod, recombinant interferon alpha-2 [IFN-alpha2b] and, celecoxib) in human leukocyte antigen (HLA)-A2+ subjects with primary PD-1 resistant immuno-oncology (IO)-refractory melanoma (who will continue the original PD-1/PD-L1 regimen for 12 weeks).
SECONDARY OBJECTIVES:
I. To evaluate the immune-related objective response rate (objective response rate [ORR]; per immune-related Response Evaluation Criteria in Solid Tumors [iRECIST];) in the above patient population treated with autologous alphaDC1/TBVA cell-based treatment plus cytokine CKM regimen followed by continued treatment with PD-1/PD-LI blockade (+/- CTLA4 blockade or LAG3 blockade).
II. Evaluate rate of durable responses (> 6 months) on the combination treatment in the above patient population treated with autologous alphaDC1/TBVA cell-based treatment plus cytokine CKM regimen followed by continued treatment with PD-1/PD-L1 blockade (+/- CTLA4 blockade or LAG3 blockade).
EXPLORATORY OBJECTIVES:
I. Examine whether the combination of peptide-loaded autologous alphaDC1 cell-based treatment and tumor-selective chemokine modulation (CKM: IFN-a2b, rintatolimod, and celecoxib) improves the overall survival (OS) and immune-related progression-free survival (iPFS) in HLA-A2+ subjects PD-1/PD-L1-refractory melanoma compared to the historical control of the best supportive care.
II. Identify the intratumoral and systemic immune correlates of the response to treatment.
OUTLINE:
Patients receive recombinant interferon alpha-2 intravenously (IV) over 30 minutes, rintatolimod IV over 2.5 hours, and celecoxib orally (PO) twice daily (BID) on days 1-3. Beginning cycle 2, patients also receive alpha-type-1 polarized dendritic cells intradermally (ID) on day 1. Treatment repeats every 3 weeks up to 4 cycles in the absence of disease progression or unacceptable toxicity. At 12 weeks, patients with progressive disease may switch to ipilimumab with or without a PD-1/PD-L1 inhibitor and patients with a complete response (CR), partial response (PR), or stable disease (SD) may switch to a PD-1/PD-L1 inhibitor or best alternative care.
After completion of study treatment, patients are followed up every 3 months for up to 2 years.

Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure
Candidate for continuation/resumption of anti-PD-1/PD-L1 blockade (in parallel to DC vaccine and CKM)
Exclusion Criteria:
Is currently being treated with systemic immunosuppressive agents, including steroids: Subjects will be ineligible until 3 weeks after removal from immunosuppressive treatments, except when they are administered as replacement therapy for endocrine dysfunction (and receive no more than 10 mg prednisone or equivalent: inhaled steroids are allowed)
