Summary

This phase II trial studies how well alpelisib works in treating participants with human papillomavirus(HPV)-associated stage I-IVA head and neck cancer that can be removed by surgery. Alpelisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Description

PRIMARY OBJECTIVES:

I. To assess the preliminary efficacy of neoadjuvant Alpelisib (BYL719) in patients with transorally-resectable, HPV+ head and neck squamous cell carcinoma (HNSCC), as measured by quantitative change in tumor size (change in T) following 14-21 days of treatment.

II. To evaluate the relationship between genomic PIK3CA activation to change in T.

SECONDARY OBJECTIVES:

I. To describe the tolerability of brief neoadjuvant exposure to BYL719. II. To assess the effect of BYL719 on the tumoral Ki-67 proliferation index. III. To evaluate viral and molecular mediators of response and resistance to BYL719, including viral messenger ribonucleic acid (mRNA), E6 and E7 oncoproteins, and phosphorylated (p)HER3.

OUTLINE

Participants receive Alpelisib orally (PO) once daily (QD) for 14-21 days in the absence of disease progression of unacceptable toxicity and then undergo surgery. Participants may receive Alpelisib for up to 28 days if surgery is delayed.

After completion of study treatment, participants are followed up for up to 12 weeks.

Eligibility

Yes No Not Sure

Inclusion Criteria

Cytologic or histologic diagnosis of oropharyngeal squamous cell carcinoma
Clinical stage I-IVa p16+ oropharyngeal squamous cell carcinoma, based upon the American Joint Committee on Cancer (AJCC) staging manual, 7th edition
No evidence of distant metastatic disease
Carcinoma must be HPV-associated, which is defined as positive for p16 protein by immunohistochemistry (IHC); p16 positivity is defined as ? 70% of tumor cells demonstrating diffuse cytoplasmic and nuclear staining for p16 by immunohistochemistry in a Clinical Laboratory Improvement Amendments (CLIA) certified pathology lab; p16 testing is standard at University Advising and Career Center (UACC) and Tucson community sites, and may be conducted locally
Appropriate and planned for primary transoral resection and/or neck dissection
Eastern Cooperative Oncology Group (ECOG) performance status 0-1
Clinically or radiologically measurable disease; the primary tumor and/or neck nodes may be measurable according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 (tumor diameter ? 1 cm; short-axis lymph node diameter ? 1.5 cm) OR by caliper measurement (tumor diameter ? 1 cm)
Absolute neutrophil count (ANC) ? 1,500/ul
Creatinine ? 1.5 x institutional upper limit of normal (ULN)
Bilirubin ? 1.5 x ULN
Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ? 2.5 x ULN
Ability to swallow and retain oral study medication, either as a whole tablet or a drinkable suspension
Have signed written informed consent

Exclusion Criteria

Subjects who fail to meet the above criteria
Prior therapy for head and neck cancer is not allowed
Poorly controlled diabetes mellitus
Patients with type II diabetes who have either a fasting plasma glucose (FPG) of ? 140 or a hemoglobin A1C (HgBA1C) of ? 6.4 will be excluded; type 1 diabetic patients will also be excluded
Patient has any of the following cardiac abnormalities
Symptomatic congestive heart failure
History of documented congestive heart failure (New York Heart Association functional classification III-IV), documented cardiomyopathy
Left ventricular ejection fraction (LVEF) < 50% as determined by multiple gated acquisition (MUGA) scan or echocardiogram (ECHO)
Myocardial infarction ? 6 months prior to enrollment
Unstable angina pectoris
Serious uncontrolled cardiac arrhythmia
Symptomatic pericarditis
Fridericia's corrected QT (QTcF) > 480 msec on the screening electrocardiogram (ECG) (using the QTcF formula) currently receiving treatment with medication that has a known risk to prolong the QT interval or inducing Torsades de Pointes, and the treatment cannot be discontinued or switched to a different medication prior to starting treatment with BYL719
Patient is currently receiving warfarin or other coumarin derived anti-coagulant, for treatment, prophylaxis or otherwise; therapy with heparin, low molecular weight heparin (LMWH), or fondaparinux is allowed
Patient is currently receiving treatment with drugs known to be moderate or strong inhibitors or inducers of isoenzyme CYP3A; the patient must have discontinued strong inducers for at least one week and must have discontinued strong inhibitors before the start of treatment; switching to a different medication prior to randomization is allowed
Patient with impaired gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral BYL719 (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
Patient with known positive serology for human immunodeficiency virus (HIV)
Patient with any other condition that would, in the Investigator?s judgment, preclude patient?s participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g. infection/inflammation, intestinal obstruction, unable to swallow oral study medication as a whole tablet or a drinkable suspension, social/psychological complications
Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test (> 5 mIU/mL)
Patient who does not apply highly effective contraception during the study and through the duration as defined below after the final dose of study treatment
Sexually active males should use a condom during intercourse while taking BYL719 and for 16 weeks after the final dose of BYL719, and should not father a child in this period, but may be recommended to seek advice on conservation of sperm; a condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid; moreover, sexually active males should not father a child for 6 months after completion of radiation; per standard clinical practice
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during the study and through at least 12 weeks after the final dose of BYL719; moreover, per standard clinical practice, women should not become pregnant for 12 months after completion of radiation; highly effective contraception is defined as either
Total abstinence: When this is in line with the preferred and usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable methods of contraception)
Female sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate); (for female study subjects, the vasectomized male partner should be the sole partner for that patient)
Use a combination of the following
Placement of an intrauterine device (IUD) or intrauterine system (IUS)
Barrier methods of contraception: Condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository
Note: Hormonal contraception methods (e.g. oral, injected, and implanted) are not allowed as BYL719 may decrease the effectiveness of hormonal contraceptives
NOTE: Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago
Severe and/or uncontrolled medical conditions such as infection requiring systemic antibiotics or anti-fungals; chronic hepatitis; severely impaired lung function
Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness
