Korábbi kezelés

• Currently receiving cancer therapy (chemotherapy, radiation therapy, immunotherapy, or biologic therapy) or investigational anti-cancer drug; *
• Any major surgery within the last 3 weeks;
• Current use of anticoagulants (warfarin, heparin, direct thrombin inhibitors) at therapeutic levels*
• Subjects with a condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of treatment; *
• Prior BRAF or MEK directed therapy; patients who have received prior interferon are eligible;
• Receipt of live attenuated vaccine within 30 days prior to the first dose of IMP. Note: Patients, if enrolled, should not receive live vaccine whilst receiving IMP and up to 30 days after the last dose of IMP; *
• Prior treatment with an anti- PD-1, anti-PD-L1, anti-PD-L2, or anti-CTLA-4 antibody;

Más betegség

• Prior malignancy except for the following: adequately treated basal cell or squamous cell skin cancer, in-situ cervical cancer, thyroid cancer (except anaplastic) or any cancer from which the patient has been disease-free for 2 years;
• Uncontrolled diabetes, hypertension or other medical conditions that may interfere with assessment of toxicity;*
• Patients with a history of uncontrolled cardiovascular or interstitial lung disease and evidence or risk of retinal vein occlusion or central serous retinopathy;
• History of retinopathy or any finding at ophthalmologic examination that is considered a risk factor for neurosensory retinal detachment/central serous chorioretinopathy, retinal vein occlusion (RVO), or neovascular macular de generation;
• Uncontrolled medical condition among which endocrine disorders (such as hypothyroidism, hyperthyroidism and diabetes mellitus);
• Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, cerebrovascular accident or transient ischemic attack, pulmonary embolism, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhoea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent;
• History of active primary immunodeficiency;
• Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients;
• Positive test for HBV sAg or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection;
• Known history of testing positive for HIV or known AIDS;

Laborértékek

• Presence of any of the following risk factors for RVO: a) Uncontrolled glaucoma with intraocular pressures ≥ 21mmHg; b) Serum cholesterol ≥Grade 2; c) Hypertriglyceridemia ≥ Grade 2; d) Hyperglycaemia (fasting) ≥Grade 2;
• Correct QT interval > 450msec to baseline, history of congenital long QT syndrome;
• Other severe medical or psychiatric conditions (like depression) or abnormalities of laboratory tests that may increase the risk associated with study participation or the assumption of Vemurafenib, Atezolizumab and Cobimetinib or that may interfere with the interpretation of study results, which in the judgment of the Investigator can make the patient not eligible for the study;

Egyéb

• Pregnancy and/or breast feeding or of childbearing potential and not practicing a reliable method of birth control;*
• Unwillingness or inability to follow the procedures required in the protocol; *
• Judgment by the investigator that the patient is unsuitable to participate in the study and the patient is unlikely to comply with study procedures, restrictions and requirements.

• Patients of either sex aged ≥18 years;
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form;
• Patients must have histologically or cytologically confirmed Stage IIIB/C/D or oligometastatic stage IV1 resectable melanoma. The definition of resectability can be determined by the patient's surgical oncologist and verified via discussion at Multidisciplinary Tumour Conference attended by melanoma medical and surgical oncology staff. Resectable tumours are defined as having no significant vascular, neural or bony involvement. Only cases where a complete surgical resection with tumour-free margins can safely be achieved are defined as resectable;
• All patients must have a BRAF V600E/K mutation status known;
• Patients must be medically fit enough to undergo surgery as determined by the surgical oncology team;
• Patients must have measurable disease, defined by RECIST 1.1;
• ECOG performance status 0-1; *
• Patients must have organ and marrow function
• Absence of any psychological, familiar or social condition that may affect compliance with study protocol and schedule follow-up;
• Female subjects of childbearing potential must have a negative pregnancy test result at baseline and must practice a reliable method of contraception for the total study duration plus 23 weeks (i.e. 30 days plus the time required for experimental drugs to undergo five half-lives) after the last dose of experimental drugs; *
• Men who are sexually active with women of childbearing potential must practice a reliable method of contraception for the total study duration plus 31 weeks (i.e. 80 days plus the time required for experimental drugs to undergo five half-lives) after the last dose of experimental drugs.
