Summary:

      This phase II trial studies how well cabozantinib-s-malate and erlotinib hydrochloride works
      in treating patients with previously treated metastatic non-small cell lung cancer.
      Cabozantinib-s-malate and erlotinib hydrochloride may stop the growth of tumor cells by
      blocking some of the enzymes needed for cell growth. Cabozantinib-s-malate may also stop the
      growth of non-small cell lung cancer by blocking blood flow to the tumor. Giving
      cabozantinib-s-malate together with erlotinib hydrochloride may be an effective treatment for
      non-small cell lung cancer.

             have not undergone successful surgical sterilization (hysterectomy, bilateral tubal
             ligation, or bilateral oophorectomy) or are not postmenopausal; postmenopause is
             defined as amenorrhea >= 12 consecutive months; note: women who have been amenorrheic
             for 12 or more months are still considered to be of childbearing potential if the
             amenorrhea is possibly due to prior chemotherapy, antiestrogens, ovarian suppression

               -  To the thoracic cavity, abdomen, or pelvis within 2 weeks before the first dose
                  of study treatment, or has ongoing complications, or is without complete recovery
                  and healing from prior radiation therapy

               -  To bone or brain metastasis within 14 days before the first dose of study
                  treatment

               -  To any other site(s) within 28 days before the first dose of study treatment

          -  The subject has received prior treatment with a small molecule kinase inhibitor or a
             hormonal therapy (including investigational kinase inhibitors or hormones) within 14
             days or five half-lives of the compound or active metabolites, whichever is longer,
             before the first dose of study treatment; prior erlotinib is required and does not
             require a 14-day wash out

          -  The subject has received any other type of investigational agent within 28 days before
             the first dose of study treatment

          -  The subject has not recovered to baseline or Common Terminology Criteria for Adverse
             Events (CTCAE) =< grade 1 from toxicity due to all prior therapies except alopecia and
             other non-clinically significant adverse events (AEs)

          -  The subject has a primary brain tumor

          -  The subject has active brain metastases or epidural disease; subjects with brain
             metastases previously treated with whole brain radiation or radiosurgery or subjects
             with epidural disease previously treated with radiation or surgery who are
             asymptomatic and do not require steroid treatment for at least 2 weeks before starting
             study treatment are eligible; baseline brain imaging with contrast-enhanced CT or MRI
             scans for subjects with known brain metastases is required to confirm eligibility

          -  The subject has prothrombin time (PT)/ International Normalized Ratio (INR) or partial
             thromboplastin time (PTT) test >= 1.3 x the laboratory ULN within 14 days before the

             such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa
             inhibitors, or antiplatelet agents (e.g., clopidogrel); low dose aspirin (=< 81
             mg/day), low-dose warfarin (=< 1 mg/day), and prophylactic low molecular weight
             heparin (LMWH) are permitted

          -  Strong cytochrome P450 (CYP)3A4 inducers and inhibitors should be avoided; selection
             of alternate concomitant medications with no or minimal CYP3A4 enzyme inhibition
             potential is recommended; because the lists of these agents are constantly changing,
             it is important to regularly consult a frequently-updated list such as
             http://medicine.iupui.edu/clinpharm/ddis/table.aspx; medical reference texts such as
             the Physicians' Desk Reference may also provide this information; as part of the
             enrollment/informed consent procedures, the patient will be counseled on the risk of
             interactions with other agents, and what to do if new medications need to be
             prescribed or if the patient is considering a new over-the-counter medicine or herbal
             product
