Combination of CM082 With JS001 in Patients With Advanced Non-Small Cell Lung Cancer (SCLC) Who Progressed on First-line Treatment: a Phase II Study
Combination of CM082 With JS001 in Patients With Advanced Non-Small Cell Lung Cancer (SCLC) Who Progressed on First-line Treatment: a Phase II Study
This study was a one-arm, single-center, phase II clinical study. Patients who meet the enrollment criteria will receive CM082 tablets 150mg once daily (qd) orally (taken within half an hour after daily breakfast) in combination with JS001 (3mg/kg, once every 2 weeks, q2w), every 28 days a treatment cycle until the disease progresses, the toxicity is intolerable, the investigator or subject decides to withdraw, loses to follow up, starts using other anti-tumor treatments or dies.
The study is divided into the following five stages--screening period, treatment period, end of treatment / withdrawal treatment, follow-up after treatment, survival follow-up.
Screening period Subjects should be informed and signed an informed consent form prior to screening assessment. Screening should be performed within 28 days prior to dosing. After the investigator confirms compliance with the inclusion criteria and does not meet the exclusion criteria, the subject may be enrolled in the study drug.
Treatment period At this stage the subject will be treated with CM082 and JS001 until disease progression, intolerable toxicity, the investigator or subject decides to quit, is lost to follow-up, begins using other anti-tumor treatments or dies.
During the trial, subjects received a safety assessment every 4 weeks; tumor assessments were performed 6 weeks after the first visit and every 8 weeks after the first tumor assessment. Tumor progression will be evaluated simultaneously according to RECIST criteria and iRECIST criteria. Subjects identified as confirmed progressive disease(iCPD) according to iRECIST criteria should discontinue treatment.
End of treatment / withdrawal treatment End of treatment(EOT)visit evaluation should be performed as soon as possible after the subject has discontinued the test drug. Anyone who discontinues treatment or withdraws from treatment for reasons other than progression of the disease should perform a safety assessment as soon as possible, while continuing to perform a tumor assessment at the same frequency as the treatment period until disease progression or initiation of other anti-tumor treatments. However, subjects who have terminated treatment due to disease progression need only undergo a safety assessment and no longer have a tumor assessment. If the subject terminates treatment due to toxicity or other reasons at the last visit and does not continue taking the test drug afterwards, the visit is considered to be the end of treatment/exit treatment visit.
Follow-up after treatment For subjects who completed the trial or withdrew their informed consent, all adverse events (AEs) and concomitant medications must be recorded up to 30 days after the last dose of the trial, and all new AEs were issued within 30 days of the last trial dose. For subjects who started using other anti-tumor therapies, AEs that were not severe and that the investigator considered unrelated to the test drug were no longer recorded.
Survival follow-up Subjects with disease progression or other anti-tumor treatments will no longer undergo safety and tumor assessment, but continue to collect data on overall survival and follow-up treatment at telephone follow-up every 12 weeks until the patient dies or loses visit.
Note: Patients who discontinue treatment due to disease progression (except for patients withdrawing informed consent, loss of follow-up, death) should continue to follow the tumor assessments according to the original frequency (no safety assessment). Once disease progression has occurred or other anti-tumor drugs have been used, a telephone survival follow-up is performed every 12 weeks thereafter.
Inclusion Criteria:
Histologically or cytologically confirmed diagnosis of recurrence after surgery, inoperable resection or metastasis advanced NSCLC (III/IV period), with no specific driver gene mutations (EGFR or ALK).
Has not received any systemic anti-tumor medication or adjust the chemotherapy regimen because of intolerance( but the treatment should be completed for at least 4 weeks prior to the first dose of study drug, and all related toxicity events have returned to normal or no more than Grade I of CTCAE 4.03, except for hair loss).
Eastern Cooperative Group (ECOG) Performance Status score of 0 or 1.
Life expectancy of at least 12 weeks.
All patients are suggested tumor tissue specimens (preferably fresh tissue specimens) for PD-L1 expression analysis prior to enrollment. If the subject did not undergo a pathological examination before participating in the trial, the collected tumor tissue specimens will also be used for pathological examination to confirm the diagnosis of NSCLC.
There is at least one measurable lesion according to the RECIST 1.1 standard and the lesion has not received radiotherapy.
Patients may have a history of brain/meningeal metastases, but must undergo topical treatment (surgery/radiotherapy) and be clinically stable for at least 3 months prior to the start of the study .If corticosteroids have been used before, they should be discontinued for at least 2 weeks before the first dose of study drug.
The level of organ function must meet the following requirements (7 days before the first dose of study drug):
Serum pregnancy test results must be negative within 7 days prior to the first dose of the test drug for women of childbearing age; males with fertility or women who are at risk of pregnancy must use highly effective methods of contraception throughout the trial (eg oral contraceptives, intrauterine contraceptive device, controlled libido or barrier contraceptive method combined with spermicide), and continued contraception for 12 months after the end of treatment.
Ability to understand the nature of this trial and give written informed consent. Willingness and ability to comply with trial and follow-up procedures.
Exclusion Criteria:
Patients who have previously received anti-PD-1, anti-PD-L1, anti-PD-L2 therapy, or VEGFR Tyrosine Kinase Inhibitors(TKI) therapy.
Patients currently receiving anti-tumor treatment.
Patients who received large surgery within 4 weeks before the first dose of the test drug or has not recovered from the side effects of this operation, received live vaccination or immunotherapy within 4 weeks before the first dose of the test drug, and radiotherapy was performed within 2 weeks.
Subjects with a history of malignancy (unless NSCLC) were excluded unless complete remission was achieved at least 2 years prior to enrollment and no further treatment was required during the study period (the following conditions are not limited: non-melanoma skin cancer) , bladder carcinoma in situ, gastric carcinoma in situ, colonic carcinoma in situ, endometrial carcinoma in situ, cervical carcinoma in situ/dysplasia, melanoma carcinoma in situ or breast carcinoma in situ)
Hematopoietic stimulating factors were received within 1 week prior to the first dose of the study drug, such as granulocyte colony-stimulating factor (G-CSF) and erythropoietin.
HIV antibody or Treponema pallidum antibody test results are positive.
If HBsAg or HBcAb is positive, hepatitis B virus(HBV) DNA should be tested. Patients should be excluded if the measurement is above the upper limit of the normal range. If HCV antibody is positive, hepatitis C virus(HCV) DNA should be tested. Patients should be excluded if the measurement is above the upper limit of the normal range.
