Summary

This phase II trial compares the effect of adding ipatasertib to pembrolizumab (standard immunotherapy) vs. pembrolizumab alone in treating patients with squamous cell cancer of the head and neck that has come back (recurrent) or has spread to other places in the body (metastatic). Ipatasertib is in a class of medications called protein kinase B (AKT) inhibitors. It may stop the growth of tumor cells and may kill them. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving ipatasertib in combination with pembrolizumab may be more effective than pembrolizumab alone in improving some outcomes in patients with recurrent/metastatic squamous cell cancer of the head and neck.

Description

PRIMARY OBJECTIVE:

I. To compare progression-free survival (PFS) in first line relapsed/metastatic (R/M) head and neck squamous cell cancer (HNSCC) patients treated with the combination ipatasertib and pembrolizumab versus pembrolizumab monotherapy treatment.

SECONDARY OBJECTIVES:

I. To evaluate the safety and tolerability of the combination ipatasertib and pembrolizumab in first line R/M HNSCC patients.

II. To describe overall response rate (ORR) and duration of response per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 in first line R/M HNSCC treated patients with the combination ipatasertib and pembrolizumab and pembrolizumab monotherapy treatment.

III. To assess changes in the tumor microenvironment by immunophenotyping with the combination ipatasertib and pembrolizumab and pembrolizumab monotherapy treatment.

IV. To assess changes in Akt, ERK, and MEK signaling with the combination ipatasertib and pembrolizumab and pembrolizumab monotherapy treatment.

V. To determine changes in immune-cell population in peripheral blood with the combination ipatasertib and pembrolizumab and pembrolizumab monotherapy treatment.

EXPLORATORY OBJECTIVE:

I. To investigate the relationship between the combination ipatasertib and pembrolizumab treatment and biomarkers which may predict response, such as tumor PD-L1 expression and alterations in the PI3K/AKT pathway.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and ipatasertib orally (PO) once daily (QD) on days 1-14 of each cycle. Cycles repeat every 21 days for a period of 24 months in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 21 days for a period of 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months until disease progression, the next line of therapy is started, or death, whichever occurs first.

Exclusion Criteria

Prior treatment with a checkpoint inhibitor given for relapsed or metastatic disease. Prior treatment with a checkpoint inhibitor for locally advanced disease as part multidisciplinary treatment is allowed
History of malabsorption syndrome or other condition that would interfere with enteral absorption or result in the inability or unwillingness to swallow pills
Patient has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. The use of physiologic doses of corticosteroids may be approved after consultation with the study principal investigator (PI)
Active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine or physiologic corticosteroid replacement for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
Type 1 or Type 2 diabetes mellitus requiring insulin at study entry are ineligible
Patients who are on a stable dose of oral diabetes medication >= 4 weeks prior to initiation of study treatment may be eligible for enrollment. Patients must meet the laboratory eligibility criteria for fasting blood glucose and hemoglobin A1c
Fasting glucose =< 150 mg/dL (8.3 mmol/L) and hemoglobin A1c =< 7.5% (58 mmol/mol)
Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to entering the study
Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1). Note: Patients with grade =< 2 neuropathy or grade =< 2 alopecia are an exception to this criterion and may qualify for the study. Note: If patients received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy
Patients who are receiving any other investigational agents
Patients with known active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment
History of allergic reactions attributed to compounds of similar chemical or biologic composition to ipatasertib or hypersensitivity (grade >= 3) to pembrolizumab and/or any of the components of the solution for injection
Treatment with strong CYP3A inhibitors or strong CYP3A inducers within 2 weeks or 5 drug-elimination half-lives, whichever is longer, prior to initiation of study drug is prohibited. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
Patients with uncontrolled intercurrent illness (including but not limited to interstitial lung disease or active, non-infectious pneumonitis) or a history of (non-infectious) pneumonitis that required steroids
Patients with psychiatric illness/social situations that would limit compliance with study requirements
Patients who are pregnant or breastfeeding, or are expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 5 months after the last dose of study treatment. A WOCBP who has a positive urine pregnancy test (e.g., within 72 hours) prior to treatment will be excluded from the study. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. Pregnant women are excluded from this study because pembrolizumab is a monoclonal antibody agent and ipatasertib is an oral AKT inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with pembrolizumab and ipatasertib, breastfeeding should be discontinued if the mother is treated with pembrolizumab or ipatasertib. Due to the potential risks, WOCBPs and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 5 months after the last dose of pembrolizumab and 28 days after the last dose of ipatasertib. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
Patients with grade >= 2 uncontrolled or untreated hypercholesterolemia or hypertriglyceridemia are excluded
Patient has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g., breast carcinoma, cervical cancer) that has undergone potentially curative therapy
History of or active inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis) or active bowel inflammation (e.g., diverticulitis)
Lung disease: pneumonitis, interstitial lung disease, idiopathic pulmonary fibrosis, cystic fibrosis, aspergillosis, active tuberculosis, or history of opportunistic infections (pneumocystis pneumonia or cytomegalovirus pneumonia)
Known clinically significant history of liver disease consistent with Child Pugh Class B or C, including active viral or other hepatitis (e.g., positive for hepatitis B surface antigen [HbsAg] or hepatitis C virus [HCV] antibody at screening), current drug or alcohol abuse, or cirrhosis
