Phase Ib Study of Alpelisib With Cisplatin in Patients With HPV+ Solid Tumor Malignancies

Stopped early · Phase 1

Conditions studied: Solid Tumors

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Able to understand and voluntarily sign the informed consent form, and able to comply with the study visit schedule and other protocol requirements. Written informed consent obtained prior to any screening procedures.
• Age ≥ 18 years.
• Dose escalation:
• Any locally advanced or metastatic solid tumor malignancy with no curative treatment options available
• Dose expansion:
• HPV-associated locally advanced or metastatic platinum-resistant solid tumor malignancy. HPV positivity defined by positive p16 immunohistochemistry or in-situ hybridization assessment of archival tissue (primary or metastatic) in a CLIA-certified laboratory. 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.
• Platinum resistance defined as prior progression (radiographic or clinical) either during or within 6 months following completion of platinum-based chemotherapy.
• Platinum-based therapy as most recent systemic therapy prior to enrollment allowed but not required
• Patients may have received any number of lines of prior systemic therapy for locally advanced/metastatic disease.
• Eastern Cooperative Oncology Group performance status ≤ 1
• Patient has adequate bone marrow and organ function as defined by the following laboratory values:
• Absolute neutrophil count (ANC) ≥ 1.0 x 10\^9/L
• Platelet count ≥ 100 x 10\^9/L
• Hemoglobin ≥ 9.0 g/dL
• 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)
• Fasting plasma glucose (FPG) ≤ 140mg/dL or 7.8 mmol/L
• 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.

You may not qualify if…

• Prior treatment with PI3K-inhibitor.
• Prior known hypersensitivity to any of the excipients of alpelisib.
• Grade ≥ 2 peripheral neuropathy.
• Grade ≥ sensorineural hearing loss.
• Patients with uncontrolled CNS metastatic involvement. However, patients with metastatic CNS tumors may participate in this study if the patient is:
• > 4 weeks from prior therapy completion (including radiation and/or surgery) to starting the study treatment
• Clinically stable with respect to the CNS tumor at the time of screening
• Not receiving steroid therapy
• Not receiving anti-convulsive medications that were started for brain metastases.
• Patients who have received prior systemic anti-cancer treatment within 4 weeks or 5 half-lives of prior to starting study treatment, whichever is shorter.
• Prior investigational therapy within 4 weeks of start of study treatment.
• Patients who have received radiotherapy ≤ 2 weeks prior to starting study drugs, with exception of palliative radiotherapy, who have not recovered from side effects of such therapy to baseline or Grade ≤ 1 and/or from whom ≥ 30% of the bone marrow was irradiated.
• 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
• Patients who have undergone major surgery ≤ 4 weeks prior to starting study treatment or who have not recovered from side effects of such procedure.
• Clinically significant cardiac disease or impaired cardiac function, such as:
• Congestive heart failure (CHF) requiring treatment (New York Heart Association (NYHA) Grade ≥ 2) or left ventricular ejection fraction (LVEF) < 50% as determined by multi-gated acquisition (MUGA) scan or echocardiogram (ECHO) at screening
• History or current evidence of clinically significant cardiac arrhythmias, atrial fibrillation and/or conduction abnormality, e.g. congenital long QT syndrome, high- grade/complete AV-blockage
• Acute coronary syndromes (including myocardial infarction, unstable angina, coronary artery bypass graft [CABG], coronary angioplasty, or stenting), < 3 months prior to screening
• QT interval adjusted according to Fredericia (QTcF) > 480 msec on screening ECG
• Patients with diabetes mellitus requiring insulin treatment or uncontrolled steroid-induced diabetes mellitus.
• 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.
• Impaired GI function or GI disease that may significantly alter the absorption of oral alpelisib (e.g. Uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or significant small bowel resection).
• 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)
