• history of aneurysms and arterial dissections. The use of VEGF pathway inhibitors in patients with or without hypertension may favor the formation of aneurysms and / or arterial dissections. Before starting cabozantinib, this risk must be carefully considered in patients with risk factors such as hypertension or history of aneurysm.

• poorly controlled hypertension [defined as systolic blood pressure (SBP) of =140 mmHg or diastolic blood pressure (DBP) of = 90 millimeters of mercury(mmHg)];

Eligible subjects must be neurologically asymptomatic and without corticosteroid treatment at the time of inclusion;

• major surgery within 2 months before to registration. Complete healing from major surgery must have occurred 1 month before registration.

Subjects with clinically relevant complications from prior surgery are not eligible

• subjects with clinically relevant ongoing complications from prior radiation therapy

• positive test for human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) related illness;

• patients with complicated, symptomatic untreated lithiasis of the bile ducts;

• any serious and/or unstable pre-existing medical, psychiatric, or other conditions that could interfere with subject's safety, provision of informed consent, or compliance to study procedures;

• previous or ongoing treatment (except for adjuvant therapies) with any of the following anti-cancer therapies: chemotherapy, immunotherapy, target therapies, investigational therapy or hormonal therapy within 28 days or five half-lives of a drug (whichever is longer) prior to the first dose of cabozantinib plus lanreotide;

• inability to swallow tablets;

• rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.
