排除标准
- •Presence of symptomatic CNS metastases, or CNS metastases that require local CNS-directed therapy (such as radiotherapy or surgery). Patients with treated brain metastases should be neurologically stable (for 4 weeks post treatment and prior to study enrollment) and off of steroids for at least 2 weeks before administration of any study drug.

- •Two or more previous systemic cytotoxic chemotherapy (chemotherapy administered with concurrent radiotherapy for local control is not counted)
- •Any major operation within 4 weeks of baseline disease assessment
- •Any medical condition that would, in the investigator's judgement, prevent the patient's participation in the clinical study due to safety concerns, compliance with clinical study procedures or interpretation of study results, including but not limited to:
- •Prior immune-related adverse events requiring treatment discontinuation
- •Ongoing symptomatic interstitial lung disease (ILD), noninfectious pneumonitis or history of drug induced interstitial lung disease
- •Impaired cardiac function or clinically significant cardiac disease, including any of the following:
- •Clinically significant and/or uncontrolled heart disease such as congestive heart failure requiring treatment (NYHA Grade ≥ 2), uncontrolled hypertension or clinically significant arrhythmia

- •Use of any live vaccines against infectious diseases (e.g. varicella, pneumococcus) within 4 weeks of initiation of study treatment.
- •Major surgery within 2 weeks of the first dose of study treatment (mediastinoscopy, insertion of a central venous access device, and insertion of a feeding tube are not considered major surgery).
- •Radiotherapy within 4 weeks of the first dose of study drug except palliative radiation to painful bony lesion (this must comprise less than 30% of the bone marrow) at least 2 weeks prior to the first dose of study drug.
- •Systemic anti-cancer therapy within 2 weeks or 5 x T ½, whichever is longer of the first dose of study treatment. For cytotoxic agents that have major delayed toxicity, e.g. mitomycin C and nitrosoureas, 4 weeks is indicated as washout period. For patients receiving CTLA-4 antagonists, 6 weeks is indicated as the washout period
- •Presence of ≥ CTCAE Grade 2 toxicity (except alopecia, peripheral neuropathy and ototoxicity, which are excluded if ≥ CTCAE Grade 3) due to prior cancer therapy
- •Previous or concurrent malignancy except for basal or squamous cell skin cancer and/or in situ carcinoma of the cervix, or other solid tumors treated curatively and without evidence of recurrence for at least 5 years prior to study entry.
- •Pregnant or lactating women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.
- •Patients receiving concomitant immunosuppressive agents or chronic corticosteroids (≥10 mg of prednisone or equivalent) at the time of first study dose
- •Other severe acute or chronic medical condition or laboratory abnormality that may increase the risk associated with trial participation
- •Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 150 days after the last dose of PDR
- •Highly effective contraception methods include:
- •Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
- •Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) total hysterectomy or tubal ligation at least 1.5 months before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment
- •Male sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner should be the sole partner for that patient.
- •Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception.
- •In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment. Women are considered post-menopausal and not of child bearing potential if they have had over 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile age appropriate (e.g. generally 40-59 years), history of vasomotor symptoms (e.g. hot flushes) in the absence of other medical justification or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy, or tubal ligation at least 1.5 months ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of child bearing potential.
- •Sexually active males unless they use a condom during intercourse while taking treatment and for 150 days after the last dose of PDR
- •A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
研究组 & 干预措施
PDR001
Experimental
PDR001 will be administered once every 3 weeks via i.v. infusions over 30 minutes, respectively. Infusions of each antibody can be extended to up to 2 hours if clinically indicated. A scheduled dose of ongoing study drugs may be delayed by up to 7 days to recover from previous AEs or a missed visit. If a scheduled dose of ongoing study drugs is delayed longer than 7 days due to an unresolved AE, the administration should be skipped and treatment resumed at the next scheduled dose. The assessment schedule will be shifted accordingly.

结局指标
主要结局
To evaluate efficacy of PDR001 by Objective Response rate by RECIST(Response Evaluation Criteria In Solid Tumors)
时间窗: Repeated tumor imaging will be performed every 2 cycle (each cycle is 21 days) after baseline imaging
In the first stage of the trial, 22 patients will be recruited, and their tumor response will be assessed RECIST criteria, which is widely used tumor assessment criteria in immuno-oncology agent trials. The best response until 6 months according to irRECIST will be evaluated, and this trial will proceed to second stage if three or more respondents (irPR or irCR) are observed among 22 patients. The response (PR or CR) should be confirmed by next disease assessment(6 weeks/2cycles after initial response). Subjects who discontinue trial treatment for a reason other than recurrence will move into the Follow-Up Phase and should be assessed every 16 weeks (± 14 days) by radiologic imaging to monitor disease status.
次要结局
- To evaluate antitumor efficacy of PDR001: OS(Overall survival)(Biopsies will be taken during the screening period (e.g., within 7 days before treatment [pre-dose]), on treatment (Day 22 of first dose) and post-treatment (e.g., within 28 days after progression))
- To evaluate antitumor efficacy of PDR001: PFS(Progression-Free Survival)(Biopsies will be taken during the screening period (e.g., within 7 days before treatment [pre-dose]), on treatment (Day 22 of first dose) and post-treatment (e.g., within 28 days after progression))
- To evaluate antitumor efficacy of PDR001(Biopsies will be taken during the screening period (e.g., within 7 days before treatment [pre-dose]), on treatment (Day 22 of first dose) and post-treatment (e.g., within 28 days after progression))
