A Phase II Study of MLN0128 (TAK-228) in Rapalog-Resistant Advanced Pancreatic Neuroendocrine Tumors (PNET)
A Phase II Study of MLN0128 (TAK-228) in Rapalog-Resistant Advanced Pancreatic Neuroendocrine Tumors (PNET)
This phase II trial studies how well sapanisertib works in treating patients with pancreatic neuroendocrine tumor that has spread to other places in the body (metastatic), does not respond to treatment (refractory), or cannot be surgically removed. Drugs such as sapanisertib may stop the growth or shrink tumor cells by blocking some of the enzymes needed for cell growth.
PRIMARY OBJECTIVE:
I. To evaluate overall response rate associated with sapanisertib (MLN0128 [TAK-228]) in patients with advanced pancreatic neuroendocrine tumors (PNETs).
SECONDARY ENDPOINTS:
I. To evaluate progression-free survival (PFS) associated with MLN0128 (TAK-228) in patients with advanced pancreatic neuroendocrine tumors (PNETs).
II. To measure the safety and tolerability of MLN0128 (TAK-228) in patients with advanced PNETs.
III. To evaluate disease control rate associated with MLN0128 (TAK-228) in patients with advanced PNETs.
IV. To measure duration of response rate associated with MLN0128 (TAK-228) in patients with advanced PNETs.
OUTLINE:
Patients receive sapanisertib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 1 year, and then yearly for 2 years.
Inclusion Criteria:
Patients must have unresectable or metastatic, histologically confirmed low or intermediate grade (Klimstra Criteria) pancreatic neuroendocrine tumor (PNET) with radiological evidence of disease progression since last treatment
Refractory disease to treatment with an mTOR inhibitor
Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements, are ineligible
Disease that is currently not amenable to surgery, radiation, or combined modality therapy with curative intent
Patients must not have poorly differentiated neuroendocrine carcinoma, high-grade neuroendocrine carcinoma, adenocarcinoid, goblet cell carcinoid and small cell carcinoma
Patients must have measurable disease
Documented radiological evidence for disease progression (measurable or nonmeasurable) =< 12 months prior to enrollment
Prior or concurrent therapy with somatostatin analogue (SSA) is permitted; a stable dose at least 2 months prior to study start and must continue on the stable dose while receiving study treatment; SSA is not considered as systemic treatment

Hemoglobin >= 10 g/dL (within less than or equal to 14 days prior to registration)
Platelets >= 100 x 10^9/L (within less than or equal to 14 days prior to registration)
Total serum bilirubin =< institutional upper limit of normal (ULN) (within less than or equal to 14 days prior to registration)
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN (within less than or equal to 14 days prior to registration)
Serum creatinine =< 1.5 X institutional ULN and creatinine clearance >= 60 ml/min (within less than or equal to 14 days prior to registration)
Glycosylated hemoglobin (HbA1c) < 7.0% (within less than or equal to 14 days prior to registration)
Fasting serum glucose =< 130 mg/dL (within less than or equal to 14 days prior to registration)
Fasting triglycerides =< 300 mg/dL (within less than or equal to 14 days prior to registration)
Diabetics are allowed if:
Women must not be pregnant or breast-feeding due to potential harm to the fetus from MLN0128 (TAK-228); all females of childbearing potential must have a blood test or urine study within 7 days of registration to rule out pregnancy; a female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
Women of child-bearing potential and men must agree to practice 1 highly effective method of contraception and 1 additional effective (barrier) method of contraception, at the same time, from the time of signing the informed consent through 90 days (for female patients) and 120 day (for male patients) after the last dose of study drug, or agree to completely abstain from heterosexual intercourse; 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; men must agree not to donate sperm during the course of this study or within 120 days after receiving their last dose of study drug
Patients who have a history of brain metastasis are eligible for the study provided that all the following criteria are met:
Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care
Exclusion Criteria:
Patient is INELIGIBLE if patient discontinued prior mTOR inhibitor due to toxicity
Patients must NOT have radiotherapy, or major surgery or active drug therapy for pNET (SSA permitted) within 4 weeks prior to study treatment start
Patient must NOT have had previous treatment with any PI3K or AKT inhibitor
NO hepatic artery embolization or cryoablation/radiofrequency ablation of hepatic metastasis within 2 months of study treatment start
Patients must NOT have previous or concurrent malignancy within 2 years; exceptions are made for patients who meet any of the following conditions:
No more than 3 prior systemic treatment regimens for advanced PNET
Patients with a history of the following within =< 6 months of study entry are NOT eligible:
Patients with known significant active cardiovascular or pulmonary disease at the time of study entry are INELIGIBLE including:
Patients with known manifestations of malabsorption due to prior gastrointestinal (GI) surgery, GI disease, or for an unknown reason that may alter the absorption of MLN0128 (TAK-228) are INELIGIBLE
Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are INELGIBLE because of the potential for pharmacokinetic interactions with MLN0128 (TAK-228)
