简要总结
The purpose of this arm of the study is to evaluate the safety of PV-001-DC (autologous monocyte-derived dendritic cells pulsed with tumor lysate) when given in combination with PV-001-DV (Dengue Virus-1 strain #45AZ5) at the dose levels that were identified in the prior 2 arms and to determine if the combination can treat advanced melanoma.
Patients will have a prescribed amount of PV-001-DV injected into one of their melanoma tumors. Patients will go to the clinic and have a needle placed in a vein. The PV-001-DC product will be infused into the patient's vein. Approximately every 3 weeks, for a total of 4 treatments, patients will receive additional infusions of PV-001-DC Patients will be at the clinic for at least 1 hour following the end of each PV-001-DC infusion and if they feel fine, they may go home.
Approximately 49 days after the first infusion, patients will have a scan to see if their tumors have changed in size. Other scans may be performed during the study at different times. Patients will also have their blood and small samples of tumors tested for changes to the immune system. After 365 days, the trial will be completed for that patient.

入选标准
- •Biopsy confirmed patients with un-resectable American Joint Committee on Cancer (AJCC), Stage III or IV melanoma who have measurable disease. Measurable disease is required, and is defined as tumor can be measured in one dimension along the longest diameter
- •Patients must have tumors that are not responsive having completed prior therapy with a Progressive Death (PD)-1 / PD-Ligand-1 (PDL-1), antagonist alone or in combination with anti-Cytotoxic T Lymphocyte Antigen 4 (CTLA-4). If the patient is positive for BRAF, the patient must have progressed on at least one BRAF inhibitor in addition to a PD-1 / PD-L1 inhibitor alone or in combination with CTLA4 for metastatic melanoma
- •Patients must be progressing after having completed one standard of care therapy for metastatic melanoma
- •Tumor specimens must be available for tumor lysates and immunological studies.
- •Tumors must be available for intratumoral injection of dengue virus. This includes cutaneous and subcutaneous lesions with ultrasound-guided injection.
- •Eastern Cooperative Oncology Group (ECOG), Performance Status of ≤ 2 (corresponds to a Karnofsky Performance Status (KPS) of ≥ 70).
- •Patients must be 18 years or older and able to give informed consent.
- •Adequate bone marrow function of White Blood Cell (WBC) count to ≥ 1,500/microliter (uL); platelet count ≥ 100,000/mm3; absolute neutrophil count (ANC) > 1,500/mm3
- •Patients must have adequate renal function by serum creatinine of ≤ 2.0 milligrams/decaliter (mg/dL).
- •Adequate hepatic function of bilirubin ≤ 2.5 mg/dL; Serum Glutamic Oxaloacetic acid Transaminase/ Serum Glutamic Pyruvic Transaminase (SGOT/SGPT) < 3× upper limit of normal (ULN).
- •Patients must have the required wash out periods from prior therapy:
- •Topical therapy: 2 weeks.
- •Chemotherapy and radiotherapy: 4 weeks.
- •Other investigational therapy: 4 weeks
- •Patients of reproductive potential and their partners must agree to use an effective (>95% reliability) form of contraception during the study and for 4 weeks following the last study drug. Patients who become pregnant during the course of the study will be withdrawn from the trial.
- •Women of reproductive potential must have a negative urine pregnancy test.
- •Patients should have a life expectancy of > 4 months.
- •Patient should be able to comply with the treatment schedule and have the ability to understand and the willingness to sign the informed consent document.
- •Patients with manageable Central Nervous System (CNS), metastases may be selected to this trial. CNS metastasis patients are eligible if the CNS metastases have had no progression for at least 4 weeks (as defined by Magnetic Resonance Imaging [MRI]/Computerized Tomography [CT]).
排除标准
- •Patients with positive antibody to any Dengue Virus serotype by tetravalent ELISA assay.
- •Patients with prior vaccinations or positive Ab detected by ELISA to: West Nile, St. Louis Encephalitis, or Yellow Fever
- •Pre-existing autoimmune or antibody mediated disease including systemic lupus erythematous, rheumatoid arthritis, multiple sclerosis, Sjogren's syndrome, autoimmune thrombocytopenia, but excluding controlled thyroid disease, or the presence of autoantibodies without clinical autoimmune disease.
- •Known history of human immunodeficiency virus (HIV) or any active immunosuppressive systemic infection or a suppressed immune system, including acquired immuno-deficiency syndrome (AIDS) or HIV positivity and known hepatitis B or C infections (HCV or HBC), as assessed by serology.
- •Patients on immunosuppressive therapy. Concurrent steroid use of not more than an equivalent of 10 mg of prednisone is allowed.
- •Any other open wounds.
- •Previous organ transplantation.
- •Patients with clinically significant dermatological disorders, as judged by the clinical investigator (e.g., eczema or psoriasis), any skin lesions or ulcers, any history of atopic dermatitis, or any history of Darier's disease (Keratosis Follicularis).
- •Patients with White Blood Cell count <1,500/uL; platelet count <100,000/mm3; absolute neutrophil count (ANC) 1,500/mm3 (Grade 2)
- •Patients with inadequate renal function by serum creatinine of >1.5 x ULN (Grade 2)
- •Patients with inadequate liver function by SGPT/SGOT > 3x ULN, and bilirubin >2.5 mg/dl (Grade 2)
- •Patients with active infection or with a fever >101°F (38.5°C) within 3 days prior to the first scheduled treatment.
