Hematology: absolute neutrophil count (ANC) =1.5×109/L; platelet count =100×109/L;
hemoglobin =90g/L Renal: serum creatinine level =1.5 × ULN; urine protein = 1+, if
urine protein > 1 +, collect 24-hour urine protein determination, and the total amount
should be = 1 g,Liver: total bilirubin = 1.5 × ULN; AST (SGOT) and ALT (SGPT) = 2.5 ×
ULN; for patients with liver metastases, ALT and AST = 5 × ULN Endocrine system:
thyroid stimulating hormone (TSH) within normal range. Note: if the TSH is not within
normal range at baseline, and T3 and free T4 are within normal range, the subject can
still meet the inclusion criteria.
Coagulation function: international normalized ratio (INR) or prothrombin time (PT),
activated partial thromboplastin time (aPTT) =1.5 × ULN (unless the subject is
receiving anticoagulation therapy, PT or aPTT just needs to be within the expected
therapeutic range of the anticoagulant).
10. Willingness and ability to comply with scheduled visits, treatment plan, laboratory
tests and other study procedures.
11. Men of reproduction ability or women of pregnant possibility [amputation of uterus,
bilateral oophorectomy or bilateral tubal ligation not performed, or prior to
menopause (total menopause =1 year)] must adopt highly-effective contraceptive methods
(e.g. oral contraceptives, intrauterine contraceptive device, abstinence of sexual
intercourse or barrier contraception in combination with spermatocide) during the
whole study, and continue contraception for 12 months after the last dose of study
drug.
Exclusion Criteria:
1. Prior exposure to immune-mediated therapy (with the exclusion of Bacillus Calmette
Guerin, BCG), including but not limited to, other anti-CTLA-4, anti-PD-1, anti-PD-L1,
or anti-PD-L2 antibodies, including therapeutic anticancer vaccines;
2. Currently participating in or having participated in another clinical study within 4
weeks prior to enrollment, unless it is an observational (non-interventional) clinical
study;
3. Radiotherapy affect more than 30% of the bone marrow or extensive radiotherapy within
4 weeks prior to enrollment;
4. Major surgery within 4 weeks prior to enrollment;
5. Use of any live vaccines within 4 weeks before enrollment. Including but not limited
to the following:mumps, rubella, measles, varicella/ herpes zoster (chicken pox),
yellow fever, Rabies, Bacille Calmette-Guérin (BCG) and typhoid vaccine (inactivated
virus vaccine allowed);
6. Treatment with immunosuppressive medications within 14 days prior to enrollment. The
following are exceptions to this criterion:
Intranasal, intraocular local steroids, or local steroid injections (eg,
intraarticular injection) Systemic corticosteroids at physiologic doses not to exceed
10 mg/day of prednisone or its equivalent Steroids as preventive medication for
hypersensitivity reactions (eg, CT scan premedication)
7. Use of antineoplastic chemotherapy, biotherapy, hormone therapy or traditional herbal
medicine t within 4 weeks prior to enrollment, except for the following:
Concomitant medication of hormonal therapy for non-cancer-related conditions (eg,
hormone replacement therapy) is acceptable; Local treatment of isolated lesions,
excluding target lesions, for palliative intent is acceptable (eg, local radiotherapy
or surgery);
8. History of (non-infectious) pneumonia/interstitial lung disease requiring steroid
treatment, or ongoing pneumonia/interstitial lung disease requiring steroid treatment;
9. Uncontrolled concomitant diseases including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable
angina, arrhythmia, interstitial lung disease, or mental illness/social conditions
consistent with the following characteristics: restricting study-specified compliance,
significantly increasing the risk of developing AEs, or affecting patients' ability to
provide informed consent form.
10. Known human immunodeficiency virus (HIV) infection (positive HIV antibody);
11. Active HBV or HCV infection; HBV DNA must be detected for patients with positive HbsAg
or HBcAb at the screening; if HBV DNA test is positive at the same time (limit of
quantitation 500 IU/ml, or reaching the positive value detected at the study center);
Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain
reaction is negative for HCV RNA.
12. Active tuberculosis;
13. Allergies and adverse drug allergy reaction; Known hypersensitivity reactions to
Toripalimab or any ingredient of Toripalimab Injection; History of serious
hypersensitivity to nab-paclitaxel, cisplatin, or its preventive medication;
14. Subjects with active central nervous system (CNS) metastasis will be excluded.
Patients who have prior therapies for brain or meningeal metastasis and has been
stabilized for = 3 months and has discontinued systemic steroids therapy (>10 mg/day
prednisone or equivalent) > 4 weeks prior to enrollment could be included. If the CNS
metastasis can be adequately treated and meet the requirement specified in the
enrollment criteria, and the neurological symptoms can be recovered to =CTCAE grade 1
prior to enrollment (except the residual sign or symptom related with CNS treatment)
for at least two weeks, the subject can participate in the study;
15. Active or previously recorded autoimmune or inflammatory diseases (including
inflammatory bowel disease, systemic lupus erythematosus, rheumatoid arthritis,
ankylosing spondylitis, etc.) within 2 years prior to enrollment. The following are
exceptions to this criterion:

hypothyroidism on a stable dose of thyroid-replacement hormone (eg, treated
Hashimoto's syndrome) or patients with psoriasis requiring no systemic treatment;
16. Having other malignant tumors that have not been recovered within past 5 years prior
to enrollment, with the exception of those have been markedly cured, or curable
cancer, such as skin basal cell carcinoma or squamous cell carcinoma, thyroid
papillary carcinoma, localized low-risk prostate cancer, carcinoma in situ of cervix
or breast; note: patients with localized low-risk prostate cancer (defined as =T2a
stage, Gleason score =6 and PSA<10ng/mL at the diagnosis of prostate cancer (if
measured) who have received radical therapy and have no biochemical recurrence of
prostate specific antigen (PSA) can participate in this study);
17. Pregnant or lactating women;
18. Previously received allogeneic hematopoietic stem cell transplantation or solid organ
