• 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,
• History of idiopathic pulmonary fibrosis, history of non-infectious pneumonitis that required steroids, current pneumonitis/interstitial lung disease, drug-induced pneumonitis, organizing pneumonia, or evidence of active pneumonitis on screening chest CT scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted,
• Has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection.
• Has a known history of HIV infection and/or of active TB (Bacillus Tuberculosis),

• Previous allogenic bone marrow transplant or solid organ transplantation,
• Has an active infection requiring systemic treatment at study entry,
• The subject has a corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms within 28 days before treatment. Note: if initial QTcF is found to be > 500 ms, two additional ECGs separated by at least 3 minutes should be performed. If the average of these three consecutive results for QTcF is ≤ 500 ms, the subject meets eligibility in this regard,
• The subject requires chronic concomitant treatment of strong CYP3A4 inducers
• The subject has experienced any of the following: Clinically-significant gastrointestinal bleeding within 6 months before the first dose of study treatment, Hemoptysis of ≥ 2.5 mL of red blood within 3 months before the first dose of study treatment, Any other signs indicative of pulmonary hemorrhage within 3 months before the first dose of study treatment, The subject has radiographic evidence of cavitating pulmonary lesion(s), The subject has tumor in contact with, invading or encasing any major blood vessels, or The subject has evidence of tumor invading the GI tract, or any evidence of endotracheal or endobronchial tumor within 28 days before the first dose of cabozantinib.
• The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions which are fully described in the study protocol: Cardiovascular disorders, Gastrointestinal disorders particularly those associated with a high risk of perforation or fistula formation, Other disorders associated with a high risk of fistula formation including PEG tube placement within 3 months before the first dose of study therapy,
• Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Note: Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
• Has an history or current evidence of any condition, therapy, or laboratory abnormality that might counfound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
• The subject is planning to have oral surgery/invasive dental procedure within the projected duration of the study, starting with the screening visit through 3 months after the last dose of study treatment or had such a procedure within 3 months of first dose of study treatment.
