- Overall response rate (ORR) at week 14 according to RECIST 1.1 in all patients receiving at least on. A patient is defined as responder if a complete response (CR) or partial response (PR) can be seen. A patient with stable disease (SD) or progressive disease (PD) will be defined as non-responder.

入选标准
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- •Men and women, age ≥ 18 years
- •Women of childbearing potential (WOCBP) must use method(s) of contraception based on the tables in Appendix
- •DTIC is teratogenic. There is an insufficient amount of information to assess teratogenicity for ICB. For a teratogenic study drug and/or when there is insufficient information to assess teratogenicity (preclinical studies have not been done), a highly effective method(s) of contraception (failure rate of less than 1% per year) is required. The individual methods of contraception and duration should be determined in consultation with the investigator. WOCBP should perform contraception for 6 months after the last dose of ICB.
- •Women of child bearing potential must have a negative serum or urine pregnancy test within 72 hours prior to the start of investigational product.
- •Women must not be breastfeeding
- •Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year (see Appendix 3). The investigator shall review contraception methods and the time period that contraception must be followed. Men that are sexually active with WOCBP must follow instructions for birth control when the half- life of the investigational drug is greater than 24 hours, contraception should be continued for a period of 90 days plus the time required for the investigational drug to undergo five half-lives. Therefore, contraception has to be performed for 8 months after the last dose of ICB.
- •Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile; see Section 3.2.3 for the definition of WOCBP) and azoospermic men do not require contraception.
- •Pretreated, histologically confirmed unresectable Stage III or Stage IV melanoma, as per AJCC staging system.
- •Patients must have received anti-PD-1/PD-L1 or combined CTLA-4/PD-1 blockade for unresectable stage III or stage IV melanoma. Patients must have shown primary resistance to ICB regimen defined as progressive disease (RECIST 1.1) without prior response (partial or complete remission as defined by RECIST 1.1) to the same regimen.
- •Measurable disease by CT or MRI per RECIST 1.1 criteria
- •Tumor tissue from an unresectable or metastatic site of disease must be obtainable during screening as well as during the ICB phase.
- •BRAF wildtype as per regionally acceptable V600 mutational status testing. BRAF mutant subjects and those with indeterminate or unknown BRAF status are not permitted to be enrolled.
- •Prior palliative radiotherapy must have been completed at least 2 weeks prior to study drug administration.
- •Screening laboratory values must meet the following criteria and should be obtained within 14 days prior to randomization: WBC ≥ 3000/uL; Neutrophils ≥ 1500/uL; Platelets ≥ 100x103/uL; Hemoglobin > 9.0 g/dL; Creatinine Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min; AST/ALT ≤ 3 x ULN (≤ 5 x ULN for subjects with liver metastases); Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL).
- •Subject re-enrollment: This study permits the re-enrollment of a subject that has discontinued the study as a pre-treatment failure (i.e., subject has not been randomized/ has not been treated). If re-enrolled, the subject must be re-consented.
排除标准
- •Active (symptomatic) brain metastases or leptomeningeal metastases. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (> 10 mg/day prednisone equivalents) for at least 2 weeks prior to study drug administration. Patients with asymptomatic brain metastases not receiving > 10 mg/day prednisone equivalents can be enrolled.
- •Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).
- •History of allergy to study drug components.
- •History of severe hypersensitivity reaction to DTIC, pembrolizumab, nivolumab or ipilimumab.
- •WOCBP who are pregnant or breastfeeding
- •Women with a positive pregnancy test at enrollment or prior to administration of study medication.
- •Prisoners or subjects who are involuntarily incarcerated.
- •Subjects who are compulsorily detained for treatment of either a psychiatric or physical (e.g., infectious disease) illness.
- •Uveal or mucosal melanoma. Patients with conjunctival melanoma can be enrolled.
- •Any serious or uncontrolled medical disorder that, in the opinion of the investigator, may increase the risk associated with study participation or study drug administration (e.g. epilepsy with the intake of phenytoin), impair the ability of the subject to receive protocol therapy, or interfere with the interpretation of study results (e.g. severe leucopenia/thrombocytopenia, severe liver or renal disorders).
- •Prior malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast.
- •Subjects with active, known or suspected autoimmune disease. Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism, adrenal or pituitary insufficiency due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
- •Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of DTIC administration. Inhaled or topical steroids, and adrenal replacement doses >10 mg daily prednisone equivalents, are permitted in the absence of active autoimmune disease.
- •Any major surgery (e.g., hip or spine surgery) less than 28 days prior to the first dose of DTIC.
- •Uncontrolled adrenal insufficiency.
- •Known history of testing positive for active Hepatitis B or Hepatitis C infections.
