Brief Summary

This phase Ib trial studies the best dose and side effects of alpelisib and cisplatin in treating patients with human papillomavirus (HPV) positive solid tumor malignancies. Alpelisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving alpelisib and cisplatin may work better in treating patients with solid tumor malignancies.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the maximally tolerated dose and recommended phase 2 dose of alpelisib in combination with weekly cisplatin.

SECONDARY OBJECTIVES:

I. To determine the objective response rate and median progression-free survival with the treatment combination in HPV positive (+) solid tumor malignancies.

II. To characterize the safety profile of the combination.

OUTLINE: This is a dose escalation study.

Patients receive alpelisib orally (PO) once daily (QD) on days 1-14 or 1-21, and cisplatin intravenously (IV) over 1-2 hours on days 1 and 8, or days 1, 8, and 15. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Availability of pathology report from CLIA-certified lab demonstrating positive HPV status by p16 IHC or in situ hybridization qualifies for eligibility determination. Analysis of fresh tumor tissue is permitted in cases where archival tissue is not available.

• Serum creatinine < 1.5 x ULN OR Estimated GFR by Cockroft-Gault equation OR 24 hour urine collection ≥ 60 ml/min
• Total serum bilirubin ≤ 1.5 x ULN (< 3 x ULN in patients with documented/suspected Gilbert's disease with concomitant direct bilirubin ≤ 1.5 x ULN)
• Alanine aminotransferase (AST) and aspartate aminotransferase (ALT) ≤ 2.5 x ULN (or ≤ 5 x ULN if liver metastases are present)

• Hemoglobin A1c < 7%
• Patient is able to swallow oral medications.
• Measurable or evaluable disease by RECIST 1.1 in dose escalation. Measurable disease by RECIST 1.1 is required in dose expansion.
• Recovery from all AEs of previous anti-cancer therapies, including surgery, chemotherapy and radiotherapy, to baseline or to CTCAE Grade ≤ 1, except for alopecia.

• Patients who are currently receiving medication with a known risk of prolonging the QT interval or inducing Torsades de Pointes (TdP) and the treatment cannot either be discontinued or switched to a different medication prior to starting study drug treatment. A list of prohibited drugs with a known risk of TdP is provided in Appendix.
• Patient is currently receiving treatment with drugs known to be 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 is allowed. (Refer to Appendix)
• Known positive serology for human immunodeficiency virus (HIV) (baseline testing not required)
• 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 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 drug and for 16 weeks after the final dose of study treatment 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.

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 16 weeks after the final dose of study treatment. 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 (both a+b):

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 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.

For women with therapy-induced amenorrhea, oophorectomy or serial measurements of FSH and/or estradiol are needed to ensure postmenopausal status.

NOTE: Ovarian radiation or treatment with a luteinizing hormone-releasing hormone (LH-RH) agonist (goserelin acetate or leuprolide acetate) is not permitted for induction of ovarian suppression.
