Brief Summary:
This phase I/II trial tests the safety, side effects, and best dose of alpelisib and whether alpelisib and carboplatin work to shrink tumors in patients with solid tumors or human papillomavirus (HPV) positive squamous cell carcinoma that has spread to nearby tissue or lymph nodes (locally advanced) or has spread to other places in the body (metastatic). Alpelisib belongs to a group of medicines called phosphatidylinositol 3-kinase (PI3K) inhibitors. This means alpelisib blocks the activity of the PI3K protein. The PI3K pathway is well known to be involved in tumor cell multiplication and survival. Blocking PI3K may reduce the ability of certain cancers to grow. Carboplatin is an anticancer drug or chemotherapy drug that binds to DNA causing damage that prevents the DNA from replicating, which prevents the cells itself from reproducing. Giving alpelisib and carboplatin may help control the disease in patients with solid tumors and HPV positive squamous cell carcinoma.

Detailed Description:

PRIMARY OBJECTIVES:

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

II. To characterize the safety profile of the combination of alpelisib and carboplatin.

III. To determine the overall response rate with the treatment combination in HPV+ solid tumor malignancies (dose expansion).

SECONDARY OBJECTIVES:

I. To determine the median progression-free survival with the treatment combination in HPV+ solid tumor malignancies.

II. To characterize the glycemic impact of the combination of alpelisib and carboplatin.

EXPLORATORY (CORRELATIVE) OBJECTIVES:

I. To investigate the relationship between hyperpolarized carbon-13 with PI3K pathway modulation serially in real time.

II. To measure the prevalence of PIK3CA mutations in the study population.

OUTLINE: This is a phase I, dose-escalation study of alpelisib followed by a phase II dose expansion study. Patients receive alpelisib orally (PO) once daily (QD) on days 1-21 and carboplatin intravenously (IV) 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 for 30 days.

Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) (Phase 1) [ Time Frame: Up to 1 cycle (1 cycle is equal to 21 days) ]
    During dose escalation, two dose levels of carboplatin will be evaluated in combination with escalating doses of alpelisib in parallel. The MTD is defined as the highest combination drug dosage not causing dose-limiting toxicities (DLT) in 33% or more of the treated patients in the first 21-day cycle of treatment.

  2. Recommended Phase 2 Dose (Phase 1) [ Time Frame: Up to 1 cycle (1 cycle is equal to 21 days) ]
    The recommended phase 2 dose will be determined during interim analysis on toxicities reported in Phase 1, and implemented during enrollment of the phase 2 cohort.

  3. Percentage of participant with reported DLT (Phase 1) [ Time Frame: Up to 1 cycle (1 cycle is equal to 21 days) ]
    Toxicity will be assessed using the NCI CTCAE, version 5.0 unless otherwise specified. A DLT is defined as an AE or abnormal laboratory value assessed as at least possibly related to the study medication, which occurs <= 21 days following the first dose of alpelisib in combination with carboplatin (Cycle 1).

  4. Percentage of participants with treatment-related adverse events [ Time Frame: Up to 3 years ]
    Percentage of participants with Grade 3 and higher adverse events classified using the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5 will be reported.

  5. Overall Response Rate Phase (Phase 2) [ Time Frame: Up to 3 years ]
    Overall response rate (ORR) will be reported for the Phase 2 cohort and defined as the number of patients with complete response (CR) or partial response (PR) using RECIST version 1.1 criteria over the total number of patients enrolled in this study. The proportion and corresponding two-sided 90% confidence interval will be reported.


Secondary Outcome Measures :
  1. Median progression-free survival (Phase 2) [ Time Frame: Up to 3 years ]
    Progression-free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first for the Phase 2 cohort

  2. Proportion of participants with abnormal glucose values over time [ Time Frame: Up to 3 years ]
    Blood glucose will be monitored continuously (every 5 minutes) during treatment using a continuous glucose monitor to characterize the ongoing glycemic impact of alpelisib. Descriptive statistics will be reported for the continuous glucose monitoring (CGM) as the proportion of participants with abnormal glucose levels over time.

14. Participant with Child-Pugh score B or C. 15. Active hepatitis B or active hepatitis C infection due to immunosuppressive effects of study drug (particularly carboplatin).

16. 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, social/psychological complications.

19. 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.

22. 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-

  1. Sexually active males should use a condom during intercourse while taking drug and for 6 months 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.
  2. 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 6 months 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):

      1. Placement of an intrauterine device (IUD) or intrauterine system (IUS)
      2. 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 alpelisib may decrease the effectiveness of hormonal contraceptives. 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 follicle stimulating hormone (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.
