Brief summary: The purpose of this study is to improve survival of patients with recurrent or metastatic Adenoid Cystic Carcinoma (ACC). This study will test the efficacy of the investigational drug, TKI258, in treating ACC.

Detailed description: Adenoid cystic carcinoma (ACC) is an uncommon malignancy that arises in secretory glands. The most common sites for the disease are the major and minor salivary glands but these tumors may also arise in the nasal cavity, lacrimal gland, tracheobronchial tree, breast or vulva. The mainstay of treatment for localized ACC is surgical resection often followed by post-operative radiotherapy. Although this leads to an initially high rate of local control, the 5-year disease-free survival rate is 50-75%. In addition, a significant proportion of the patients develop distant metastases, most frequently in the lung. Compared to other malignancies, ACC tends to grow more slowly. Thus, patients often do well in the short-term but long-term prognosis remains guarded and most succumb to the disease within 10-15 years. To date, systemic therapies have proven to be largely ineffective against recurrent and metastatic ACC. Dovitinib is a broad-targeted-profiled RTK inhibitor active against these three RTKs (VEGF, FGF and PDGF) involved in tumor cell growth. Based on its potency as an inhibitor of these RTKs both in vitro and in vivo, and the compound's oral availability, several clinical trials of dovitinib are underway. This phase II trial will test the hypothesis that dovitinib will be active against this disease. The rationale is based on pre-clinical studies that suggest that dovitinib suppresses tumor growth by blocking constitutive signaling of the fibroblast growth factor receptor-1 (FGFR1) and animal studies in which the drug proved to be active against primary ACC xenografts.

Eligibility criteria: Inclusion Criteria:

Patients eligible for inclusion in this study have to meet all of the following criteria:

1. Patients must have histology or cytology studies that confirm the diagnosis of adenoid cystic carcinoma. (Note: Subsequent central review of the pathology slides will be provided by Drs. Christopher Moskaluk or Henry Frierson, Department of Pathology at the University of Virginia Health Sciences Center).
2. Patients must have recurrent and/or metastatic disease that is not amenable to potentially curative surgical resection or radiotherapy.
3. Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as \>10 mm with spiral CT scan (or \>20 mm with conventional techniques). Pathologic lymph nodes are measured by shortest diameter as per RECIST.
4. Patients must have serial imaging that allows measurement of tumor growth rates by change point analysis:

1. The remote baseline study scan must be within six calendar months of the immediate pre-study scan.

2. The remote baseline scan must have measurable disease ≥ 10 mm for non-pulmonary lesions or ≥ 4 mm for pulmonary metastases that show subsequent progression.

3. Comparison of the remote baseline and subsequent studies must show progressive disease in 1-5 selected target lesions based on the following:

1. Modified RECIST criteria (i.e. proportional increase of 1.2 or the appearance of new lesions) AND/OR
2. Progression by change point analysis with an increase in the slope of the average tumor measurements of at least 0.22 b

a = "remote baseline scan" refers to scan done prior to pre-study scan which is used to determine pre-treatment tumor growth rate.

b = the estimated mean minus one standard deviation based on analysis of progressive tumors from untreated patients with ACC.

5. Life expectancy \> 16 weeks.

6. ECOG (WHO) performance status 0-2

7. Age ≥ 18 years old

8. Patients must have the following laboratory values:

* Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
* Platelets ≥ 100 x 109/L
* Hemoglobin (Hgb) \> 9 g/dL
* Serum total bilirubin: ≤ 1.5 x ULN
* ALT and AST ≤ 3.0 x ULN
* Serum creatinine ≤ 1.5 x ULN or serum creatinine \>1.5 - 3 x ULN if calculated creatinine clearance (CrCl) is ≥ 30 mL/min using the Cockroft-Gault equation, see formula below:

CrCl = \[140-age (years)\] x weight (kg) / \[72 x serum Cr (mg/dL)\] (if patient is female multiply the above by 0.85)

9. Patients who give a written informed consent obtained according to local guidelines

Exclusion Criteria:

Patients are ineligible for this study if he or she has any of the following:

1. Patients with brain metastases
2. Patients with another primary malignancy within 3 years prior to starting study drug, with the exception of adequately treated in-situ carcinoma of the uterine cervix, or skin cancer (such as basal cell carcinoma, squamous cell carcinoma, or non-melanomatous skin cancer)
3. Patients who have received the last administration of an anticancer therapy including chemotherapy, immunotherapy, hormonal therapy and monoclonal antibodies (but excluding nitrosurea, mitomycin-C, targeted therapy and radiation) ≤ 4 weeks prior to starting study drug, or who have not recovered from the side effects of such therapy
4. Patients who have received the last administration of nitrosurea or mitomycin-C ≤ 6 weeks prior to starting study drug, or who have not recovered from the side effects of such therapy

6. Patients who have had radiotherapy ≤ 4 weeks prior to starting study drug or ≤ 2 weeks prior to starting study drug in the case of localized radiotherapy (e.g. for analgesic purpose or for lytic lesions at risk of fracture), if the measurable lesions are outside the radiation field. Also excluded would be those who have not recovered from toxicity radiotherapy.
7. Patients who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury ≤ 4 weeks prior to starting study drug, or patients who have had minor procedures, percutaneous biopsies or placement of vascular access device ≤ 1 week prior to starting study drug, or who have not recovered from side effects of such procedure or injury
