About
Pulse is a randomized non-inferiority phase III clinical trial assessing a new mode of immunotherapy administration based on increased interval time between 2 infusions as maintenance treatment in Pulse arm compared with the conventional administration in Control arm.
In both treatment arms, pembrolizumab alone or combined with pemetrexed is allowed as maintenance treatment. Indeed :
In Pulse arm : Pembrolizumab 200 mg will be administered to patients every 6 weeks (Q6W) plus, in the absence of contra-indication pemetrexed 500 mg/m^2 will be administered every 3 weeks (Q3W).
In control arm : Pembrolizumab 200 mg will be administered to patients every 3 weeks (Q3W) or 400 mg every 6 weeks plus,in the absence of contra-indication pemetrexed 500 mg/m^2 will be administered every 3 weeks (Q3W).

Inclusion criteria

B) To be checked before the maintenance phase (for all patient) :
Histologically or cytologically confirmed diagnosis of non-squamous non-small cell lung cancer (NSCLC).
Non-operable / non-irradiable stage III or stage IV.
Received 3 or 4 cycles of induction treatment combination with pembrolizumab plus platinum (cisplatin or carboplatin) and pemetrexed.
Patient must be eligible to receive maintenance pembrolizumab with or without pemetrexed, last induction chemotherapy cycle within 42 days before randomization.
Stable disease, partial or complete response according to RECIST 1.1 criteria after induction chemotherapy and pembrolizumab. Targets lesions are not required before randomization.
In the presence of an EGFR mutation, an ALK or ROS1 rearrangement the patient must have received at least one specific targeted therapy line (not needed a second time if already checked before induction phase).
Patients with baseline brain metastases will be eligible in case of stability or no evidence of progression and if they remain clinically stable.
Age ≥ 18 years old.
Performance status 0 or 1.
Signed informed consent (only for patient included after induction phase).
Patient affiliated to a social security system or beneficiary of the same.
Creatinine clearance > 30 ml/min by Cockcroft-Gault* or MDRD in case that patient will start maintenance just with pembrolizumab but ≥ 45 ml/min if the patient will receive pemetrexed plus pembrolizumab.
*Cockcroft- Gault Formula:
Neutrophils ≥ 1500/μL and platelets ≥ 100 000/μL.
Bilirubin ≤ 1.5 upper limit normal (ULN).
Transaminases, Alkaline phosphatase ≤ 2.5 x the ULN except in case of liver metastases (5 x ULN).
Patients might have received platinum-based chemotherapy as an adjuvant or neoadjuvant treatment, or with radiotherapy for a localized lung cancer, provided that the chemotherapy was ended more than 6 months before the first cycle of induction chemotherapy.
Patients might have received previous immune checkpoint inhibitors as an adjuvant or neoadjuvant treatment, or as a consolidation treatment after radiotherapy for a localized lung cancer, but the immune checkpoint inhibitors must be finished at least than 12 months before the first cycle of induction chemotherapy for advanced stage.
A woman is eligible for the study if she is no longer likely to procreate (physiologically unfit to carry out a pregnancy), which includes women who have had: a hysterectomy, an oophorectomy, a bilateral tubal ligation.
Post-menopausal women:
Women who are likely to procreate are eligible if they have a negative serum pregnancy test in the week before the first dose of treatment and preferably as close as possible to the first dose and if they agree to use an effective contraceptive method during the course of the study through 4 months after the last dose of study medication.
Sexually active males patients must agree to use condom during the study and for at least 4 months after the last study treatment administration. Also, it is recommended their women of childbearing potential partner use a highly effective method of contraception.
