Purpose

This phase II trial tests whether ado-trastuzumab emtansine works to shrink tumors in patients with HER2-positive salivary gland cancer that has come back (recurrent), spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Trastuzumab emtansine is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called emtansine. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers emtansine to kill them. Trastuzumab emtansine may work better compared to usual treatment of chemotherapy with docetaxel and trastuzumab in treating patients with salivary gland cancer.

Inclusion Criteria

  • Pathologically (histologically or cytologically) proven diagnosis of HER2-positive salivary gland cancer (SGC) - Note: The majority of HER2-positive SGCs are salivary duct carcinoma (SDCs), but to a lesser extent, other SGC subtypes can be HER2-positive (e.g., adenocarcinomas, mucoepidermoid carcinomas, etc.) and are eligible to be included on the study. Additionally, pathologists may sign out SDCs under other descriptors (e.g., ex-pleomorphic adenoma, adenocarcinoma), and these would be eligible if they are HER2-positive. - Note: HER2 evaluation based on local site immunohistochemistry (IHC), fluorescent in-situ hybridization (FISH), or local/commercial next-generation sequencing (NGS) is required. Any one of the following criteria observed in a primary tumor or metastasis would meet the study definition for "HER2-positive": - Immunohistochemistry (IHC) (3+) per the College of American Pathologists (CAP) breast cancer guidelines - Gene amplification by FISH (HER2/CEP17 ratio >= 2.0) - Gene amplification by NGS (fold change > 2) - Patients with unresectable disease who are not candidates for curative surgery or radiation OR recurrent OR metastatic disease that is evident on radiologic imaging - Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression - Patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy - Measurable or non-measurable disease by the RECIST v1.1 criteria - History/physical examination within 30 days prior to registration - The following imaging within 60 days prior to registration: - Computed tomography (CT) or magnetic resonance imaging (MRI) of the neck (diagnostic quality with contrast, unless contraindicated) AND - CT scan of the chest (diagnostic quality with contrast, unless contraindicated) AND - CT or MRI of the abdomen and pelvis, if clinically indicated (diagnostic quality with contrast, unless contraindicated) - Age >= 18 - Left ventricular ejection fraction (LVEF) >= 50% assessed by echocardiogram or multigated acquisition (MUGA) scan within 30 days prior to registration - Absolute neutrophil count (ANC) >= 1,500 cells/mm^3 (within 14 days prior to registration) - Platelets >= 100,000 cells/mm^3 (within 14 days prior to registration) - Hemoglobin >= 9.0 g/dL (within 14 days prior to registration) (Note: The use of transfusion or other intervention to achieve hemoglobin [Hgb] >= 9.0 g/dL is acceptable.) - Serum creatinine =< 1.5 x upper limit of normal (ULN) OR calculated creatinine clearance (CrCl) >= 30 mL/min by the Cockcroft-Gault formula (within 14 days prior to registration) - Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 1.5 x institutional ULN (within 14 days prior to registration) - Known human immunodeficiency virus (HIV) infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months prior to registration are eligible for this trial. Testing is not required for entry into protocol - For patients with known evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated - Note: Known positive test for hepatitis B virus surface antigen (HBV sAg) indicating acute or chronic infection would make the patient ineligible unless the viral load becomes undetectable on suppressive therapy. Patients who are immune to hepatitis B (anti-Hepatitis B surface antibody positive) are eligible (e.g., patients immunized against hepatitis B) - For patients with a known history of hepatitis C virus (HCV) infection, they must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load - Note: Known positive test for hepatitis C virus ribonucleic acid (HCV RNA) indicating acute or chronic infection would make the patient ineligible unless the viral load becomes undetectable on suppressive therapy - Negative urine or serum pregnancy test (in persons of childbearing potential) within 14 days prior to registration. Childbearing potential is defined as any person who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal - Willing to use highly effective contraceptives for participants of childbearing potential (participants who may become pregnant or who may impregnate a partner) during therapy and for 7 months following last dose of study drug; this inclusion is necessary because the treatment in this study may be significantly teratogenic (See Section 9 for definition of highly effective contraception). Women must refrain from donating eggs during this same period - Men with partners of childbearing potential must be willing to use a highly effective form of non-hormonal contraception or two effective forms of non-hormonal contraception by the patient and/or partner, and to continue the use of contraception for the duration of study treatment and for at least 7 months after the last dose of study treatment. Male patients whose partners are pregnant should use condoms for the duration of the pregnancy. Men must refrain from donating sperm during this same period - Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial - The patient or a legally authorized representative must provide study-specific informed consent prior to study entry and, for patients treated in the U.S., authorization permitting release of personal health information

Detailed Description

PRIMARY OBJECTIVE: I. To determine if trastuzumab emtansine (ado-trastuzumab emtansine [T-DM1]) shows better progression-free survival (PFS) when compared to docetaxel plus trastuzumab (TH) in recurrent and/or metastatic (R/M) HER2-positive salivary gland cancer (SGC) patients who have not previously received HER2 therapy for unresectable or recurrent and/or metastatic disease, as determined by local assessment. SECONDARY OBJECTIVES: I. To compare the overall response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria between arms. II. To compare overall survival (OS) between arms. III. To compare toxicity using Common Terminology Criteria for Adverse Events (CTCAE) v5.0 criteria between arms. IV. To assess patient-reported toxicity, as measured by the patient reported outcome (PRO)-CTCAE, between arms, and explore patient-reported symptomatic adverse events (AEs) for tolerability of each treatment arm as measured by the PRO-CTCAE. EXPLORATORY OBJECTIVES: I. To assess the ORR in patients who receive crossover treatment to T-DM1/TH following disease progression on the TH arm/T-DM1 arm. II. To collect blood and tissue specimens for future translational science studies to examine how tumor genetics, HER2 signaling output/expression, and HER2 tumoral heterogeneity impact TH and T-DM1 efficacy. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive docetaxel intravenously (IV) over 60 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive trastuzumab IV over 90 minutes on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive trastuzumab emtansine IV over 90 minutes on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
