About
This is a phase II open-label randomized clinical trial of MK-3475 (Pembrolizumab) on previously treated non-small cell lung cancer (NSCLC) patients . This drug has shown to allow partial response according to the immune-related response criteria and the response evaluation criteria in solid tumors (RECIST). The main endpoint is to compare the overall response rate (ORR) of MK-3475 with docetaxel or docetaxel alone in patients with advanced NSCLC.
Full description
MK-3475 (MK-3475) is an IgG4 monoclonal antibody to PD1, which received a 'breakthrough therapy' designation for advanced melanoma from the FDA in January 2013. Preliminary results from the NSCLC cohort of a phase I dose expansion trial of MK-3475 were presented at the 2013 World Conference on Lung Cancer meeting. MK-3475 was administered intravenously every three weeks, and continued until disease progression based upon immune related response criteria (irRC) or unacceptable toxicity. IrRC take into account the potential for different patterns of response that can be seen with immunotherapy. Of the 38 patients with previously treated advanced NSCLC evaluable for efficacy, 9 (24 percent) achieved at least partial response by irRC. Standard oncology criteria for response (Response Evaluation Criteria In Solid Tumors, RECIST were available for 33 of these patients, with at least a partial response in seven patients (21 percent). Median overall survival was 51 weeks. Therapy was well tolerated, with one case of pneumonitis (grade 2) and one case of pulmonary edema (grade 3) reported. Tumor PDL1 expression (assessed with a different assay than that used for the trials evaluating Nivolumab and MPDL3280A; antibody used undisclosed) was available for 33 of the patients who had irRC assessments and 29 of those with standard oncology (RECIST) assessment. Of the 9 patients with PDL1 positivity and irRC response data, 6 achieved at least partial response (67 percent); of the 7 patients with PDL1 positivity and standard oncology response data, 4 achieved response (57 percent). Of note, 1 of 24 patients with PDL1 negativity achieved response by irRC; 2 of 22 patients with PDL1 negativity had response by standard oncology criteria (RECIST).
Based upon these results, a randomized phase II trial comparing MK-3475 to standard salvage docetaxel in patients with advanced NSCLC has been launched (NCT01905657), however there is no study in which the synergistic activity of Docetaxel + MK-3475 were evaluated, this could open the possibility of using this drug concurrently with Docetaxel as standard therapy in patients with progression of the disease despite a double platinum-based regimen.
Measure the expression levels of PD1/PD-L1/PD-L2 subpopulations tumor cells of patients with NSCLC who come to the clinic of the National Cancer Institute and relevant way, associating their role forecast and its potential as a biomarker, relating the PD-L1 levels with clinicopathologic characteristics of the patients studied.

Target Population
Subjects with locally advanced NSCLC of squamous cell and non-squamous cell (adenocarcinoma and big cells) histological or cytologically documented , those who submit Stage IIIB / IV or recurrent disease after receiving radiation treatment or surgical resection
Men and women ≥ 18 years of age.
Performance status Eastern Cooperative Oncology Group ( ECOG ) ≤ 1.
Subjects must have measurable disease by CT or MRI according to RECIST 1.1 criteria Radiographic Evaluation of Tumor on in the span of 28 days before randomization.
The target lesions may be located on a previously irradiated field exists if documented progression of disease (radiographic) in that site. Subjects progression or recurrence of the disease must have experienced during or after prior chemotherapy regimen containing platinum in metastatic disease.
This includes individuals who meet the following criteria:
must be available a blood sample, for evaluation of biomarkers. Samples must be received by the central laboratory before randomization.
All baseline laboratory requirements will be evaluated , and must be obtained -14 days of randomization. The screening laboratory values must meet the following criteria:
i) WBC ≥ 2000/μL ii) iNeutrophils ≥ 1500/μL iii) Platelets ≥ 100 x 10 ³ / uL iv) Hemoglobin ≥ 9.0 g / dL v) Serum creatinine ≤ 1.5 x ULN or creatinine clearance > 40 mL / min (using the Cockcroft / Gault ) Women : CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg / dL Males: CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg / dL vi) ≤ 1.5 X ULN AST vii) ≤ 1.5 X ULN ALT viii) Total bilirubin ≤ 1.5x ULN (except for subjects with Gilbert 's Syndrome who must have total bilirubin < 3.0 mg / dL ) h ) pretreatment with radiotherapy or radiosurgery at least 3 weeks must be completed before randomization.
i ) Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
Age and Reproductive Status
Subjects must:
Demonstrate adequate organ function as defined in Table 1, all screening labs should be performed within 10 days of treatment initiation.
Exclusion criteria
The subject must be excluded from participating in the trial if the subject:
Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of treatment.
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 had a prior monoclonal antibody 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.
Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy.
