Full description
This is a multi-center exploratory phase II trial of intravenous (IV) Pembrolizumab MK-3475 as second or further line with advanced Non-small cell Lung Cancer (NSCLC) who have failed to a prior treatment with anti-PDL1 drug.
110 patients will be enrolled in this trial to examine the efficacy and outcomes of these patients.
In addition to the usual procedures in a phase II study (evaluation of response, toxicity, etc.) special attention will be paid in this trial to the molecular assessment in biological samples.
Subjects will receive Pembrolizumab at a fixed dose of 200 mg every 3 weeks (Q3W). Subjects will be evaluated with radiographic imaging to assess response to treatment. Investigators will make all treatment-based decisions using the Immune-Related Response Criteria (irRC). However, for determination of overall response rate (ORR) and progression-free survival (PFS), the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 will be used.
Adverse events will be monitored throughout the trial and graded in severity according to the guidelines outlined in the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Treatment with Pembrolizumab will continue until documented disease progression, unacceptable adverse event(s), intercurrent illness that prevents further administration of treatment, investigator's decision to withdraw the subject, subject withdraws consent, noncompliance with trial treatment or procedure requirements, or administrative reasons.
After the end of treatment, each subject will be followed for a minimum of 30 days for adverse event monitoring (serious adverse events will be collected for up to 90 days after the end of treatment unless the subject starts a new anticancer therapy between days 31 and 90). Subjects will have post-treatment follow-up for disease status, including initiating a non-study cancer treatment and experiencing disease progression, until death, withdrawing consent, or becoming lost to follow-up.
Participation in this trial will be dependent upon supplying tumor tissue from a newly obtained formalin-fixed specimen from locations not radiated prior to biopsy. The specimen will be evaluated at a central laboratory facility for expression status of PD-L1 in a prospective manner. Only subjects whose tumors express PD-L1 as determined by the central laboratory facility will be eligible for inclusion in this study. Also it is highly recommend to send archival tumor tissue from the patient.

Inclusion criteria
Patients with hystologically or cythologicalconfirmed NSCLC advanced or locally advanced disease (according to 8th version of the International Association for the Study of Lung Cancer Staging Manual in Thoracic Oncology) not amenable to radical treatment (IIIA, IIIB, IIIC, IV), squamous or non-squamous, recurrent after at least one prior line.
The subject must be willing and able to provide written informed consent/assent for the trial.
Patient must be aged ≥ 18 years of age on day of signing informed consent.
Measurable disease (at least 1 lesion) based on RECIST 1.1. Patients will not be eligible if this lesion was irradiated before inclusion.
Documented prior benefit (Stable Disease, Partial Response, Complete Response) to check point PD1/PDL1 inhibitor (Nivolumab, Pembrolizumab, Durvalumab, Atezolizumab, Avelumab or others) for at least 16 weeks (Stable Disease, Partial Response, Complete Response) and progression while on treatment (or <12 weeks after stopping) with the same PD-1/PD-L1 inhibitors. These patients should have received subsequent treatment with Chemotherapy for at least 4 courses (Cohort 1) OR Documented prior benefit (Stable Disease, Partial Response, Complete Response) to check point PD1/PDL1 inhibitor (Nivolumab, Pembrolizumab, Durvalumab, Atezolizumab, Avelumab or others) for at least 16 weeks (Stable Disease, Partial Response, Complete Response) and progression >12 weeks after stopping treatment (Cohort 2). No subsequent treatment before rechallenge is allowed in this cohort
Patient must be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. PDL1 must be evaluable and at least 1% positive in tumor tissue. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. Subjects for whom newly-obtained samples cannot be provided (e.g. inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the Sponsor. Note: If a new sample core or excisional biopsy cannot be obtained but the patient can be included in the study and start the treatment and the archival tumor tissue could be sent afterwards for the central laboratory confirmation. If no previous PDL1 result is available from the archival tissue, the patient cannot be included in the trial until central laboratory PDL1 result is available. Other cases could be consulted with the trail chair.
Have a performance status of 0-1 on the ECOG Performance Scale.
Demonstrate adequate organ function, all screening labs should be performed within 7 days of treatment initiation.
Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
Female subjects of childbearing potential must be willing to use an adequate method of contraception (for the course of the study through 120 days after the last dose of study medication).
Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
Male subjects of childbearing potential must agree to use an adequate method of contraception (starting with the first dose of study therapy through 120 days after the last dose of study therapy).
Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
All patients will be required to submit a tumor sample for PD-L1 IHC expression. If the sample is inadequate for analysis, another sample could be provided. If a new sample cannot be obtained due to technical or clinical reasons, archival tissue can be sent. Other cases could be consulted with the trial chair.

Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.
Has a known history of active TB (Bacillus Tuberculosis)
Hypersensitivity to pembrolizumab or any of its excipients.
Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent.
Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study.
Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.

This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
