Axitinib and Avelumab in Treating Patients With Recurrent or Metastatic Adenoid Cystic Carcinoma

Study Overview
=================
Brief Summary
-----------------
This phase II trial studies how well axitinib and avelumab work in treating patients with adenoid cystic carcinoma that has come back or spread to other places in the body. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving axitinib and avelumab together may help to control adenoid cystic carcinoma.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. Assess the objective response rate (ORR) to axitinib and avelumab combination according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria patients with recurrent or metastatic adenoid cystic carcinoma (ACC) who have evidence of disease progression within 6 months prior to study enrollment. SECONDARY OBJECTIVES: I. Assess ORR to axitinib and avelumab combination according to immune-related (ir)RECIST criteria patients with recurrent or metastatic adenoid cystic carcinoma (ACC). II. Evaluate median progression free survival (PFS), PFS rate at 6 months after start of treatment. III. Evaluate median overall survival (OS), OS rate at 6 months after start of treatment. IV. Evaluate duration of response (DoR). V. Evaluate safety and toxicity. EXPLORATORY OBJECTIVES: I. Assess molecular markers associated with response and resistance to the study combination using tissue and/or plasma obtained from study participants. OUTLINE: Patients receive axitinib orally (PO) twice daily (BID) on days 1-28 and avelumab intravenously (IV) over 1 hour on days 1 and 15. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 and 90 days and then every 6 months thereafter.

Acceptable methods of contraception include total and true sexual abstinence, hormonal contraceptives that are not prone to drug-drug interactions (intra uterine system [IUS] levonorgestrel intra uterine system [Mirena], medroxyprogesterone injections [Depo-Provera]), copper-banded intra-uterine devices, and vasectomized partner. All hormonal methods of contraception should be used in combination with the use of a condom by their sexual male partner. Females of childbearing potential are defined as those who are not surgically sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or postmenopausal (defined as 12 months with no menses without an alternative medical cause) Women will be considered post-menopausal if they have been amenorrheic for the past 12 months without an alternative medical cause. The following age-specific requirements must also apply: Women < 50 years old: they would be considered post-menopausal if they have been amenorrheic for the past 12 months or more following cessation of exogenous hormonal treatments. The levels of luteinizing hormone (LH) and follicle-stimulating Hormone (FSH) must also be in the post menopausal range (as per the institution). Women >= 50 years old: they would be considered post-menopausal if they have been amenorrheic for the past 12 months or more following cessation of all exogenous hormonal treatments, or have had radiation-induced oophorectomy with the last menses > 1 year ago, or have had chemotherapy-induced menopause with > 1 year interval since last menses, or have had surgical sterilization by either bilateral oophorectomy or hysterectomy Non-sterilized males who are sexually active with a female partner of childbearing potential must use adequate contraception for the duration of the study and 30 days after the last dose of study medication. Adequate contraception methods include: birth control pills (e.g. combined oral contraceptive pill), barrier protection (e.g. condom plus spermicide, cervical/vault cap or intrauterine device), and abstinence. Patients should not father a child for 6 months after completion of the study medication. Patients should refrain from donating sperm from the start of dosing until 6 months after discontinuing the study medication. If male patients wish to father children they should be advised to arrange for freezing of sperm samples prior to the start of the study medication For patients with hypertension, upon entry into study must have blood pressure of < 140/90 Corrected QT interval (QTc) < 470 msec Exclusion Criteria: Current use of immunosuppressive medication, EXCEPT for the following: Intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection) Systemic corticosteroids at physiologic doses =< 10 mg/day of prednisone or equivalent Steroids as premedication for hypersensitivity reactions (e.g., computed tomography [CT] scan premedication) Active autoimmune disease that might deteriorate when receiving an immuno-stimulatory agent.

Adequately curative intent treated initial stage non-melanoma skin cancers; in situ carcinoma of the cervix; breast carcinoma in situ; low-grade local bladder cancer; and low-risk prostate cancer undergoing active surveillance will be allowed Pregnant women are excluded from this study. Based on its mechanism of action. Avelumab can cause fetal harm when administered to a pregnant woman. In animal models, the PD-1/PD-L1 signaling pathway is important in the maintenance of pregnancy through induction of maternal immune tolerance to fetal tissue. Human IgG1 immunoglobulins are known to cross the placenta. Therefore, avelumab has the potential to be transmitted from the mother to the developing fetus. Blockade of PD-L1 signaling has been shown in murine models of pregnancy to disrupt tolerance to the fetus and to result in an increase in fetal loss. Therefore, potential risks of administering avelumab during pregnancy include increased rates of abortion or stillbirth. Advise females of reproductive potential to use effective contraception during treatment with avelumab and for at least one month after the last dose of avelumab Lactating females: There is no information regarding the presence of avelumab in human milk, the effects on the breastfed infant, or the effects on milk production. Since many drugs including antibodies are excreted in human milk, advise a lactating woman not to breastfeed during treatment and for at least one month after the last dose of avelumab due to the potential for serious adverse reactions in breastfed infants Prior treatment with immune checkpoint inhibitor (e.g. anti-PD-1/PD-L1) Prior treatment with VEGF or VEGFR inhibitors (e.g. lenvatinib, bevacizumab)
