There is a need for more effective therapies for patients with advanced NSCLC driven by the
RAS/MEK/ERK pathway. These tumors are generally aggressive, are almost exclusively of
non-squamous histology, and represent the largest group of patients with advanced NSCLC
harboring specific driver mutations in Western populations.
Based on recent preclinical and clinical evidence, mitogen-activated protein kinase kinase
(MEK)-inhibition plus first-line chemotherapy is a promising new treatment for patients with
NSCLC and KRAS [v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog] mutations.
Binimetinib is a medication without marketing authorization. Pemetrexed and cisplatin have
marketing authorization in Switzerland and in EU for the treatment of non-small cell lung
cancer (NSCLC) and will be administered as standard backbone treatment according to their
Swissmedic-approved indication, dose and route of administration. Binimetinib, pemetrexed and
cisplatin are IMP in the context of this phase I trial.

longer on corticosteroids.

wound healing is required prior registration),
- in situ carcinoma of the cervix, treated curatively and without evidence of
recurrence for at least 5 years prior registration,
- superficial bladder cancer, prostate intraepithelial neoplasm, other noninvasive
or indolent malignancy, or other solid tumor treated curatively and without
evidence of recurrence for at least 5 years prior registration.
- Leptomeningeal disease.
- Concurrent radiotherapy (patients with prior radiotherapy other than for brain
metastases ≥ 7 days prior to registration can be enrolled).
- Previous systemic therapy for advanced NSCLC; previous adjuvant or neoadjuvant
chemotherapy allowed if last dose was administered at least 6 months ago.
- Major surgery within 3 weeks before registration.
- Concurrent treatment with any other experimental drug or other anticancer therapy.
- Impaired cardiovascular function or clinically severe or uncontrolled cardiovascular
diseases, including any of the following:
- congestive heart failure NYHA III or IV,
- history of acute coronary syndromes (including myocardial infarction, unstable
angina, coronary artery bypass grafting, coronary angioplasty, or stenting) < 6
months prior to registration,
- symptomatic chronic heart failure (G2 or higher), history or current evidence of
clinically significant cardiac arrhythmia requiring medication and/or conduction
abnormality < 6 months prior to registration except atrial fibrillation and
paroxysmal supraventricular tachycardia.
- Uncontrolled arterial hypertension defined as persistent elevation of systolic blood
pressure ≥ 150 mmHg or diastolic blood pressure ≥ 100 mmHg despite medical treatment.
- History or current evidence of retinal vein occlusion (RVO) or current risk factors to
RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyper-viscosity or
hypercoagulability syndromes); history of retinal degenerative disease.
- History of Gilbert's syndrome.
