Study Description

Brief Summary:

This phase I/II trial studies the side effects and best dose of sapanisertib and to see how well it works compared to pazopanib hydrochloride in treating patients with sarcoma that is too large to be removed (locally advanced) or has spread to other areas of the body (metastatic). Sapanisertib and pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the safety and maximum tolerable dose of sapanisertib (MLN0128 [TAK-228]) within this patient population. (Phase I) II. To determine the differences in progression-free survival (PFS) in patients with sarcoma who receive MLN0128 (TAK-228) as compared to pazopanib (pazopanib hydrochloride). (Phase II)

SECONDARY OBJECTIVES:

I. To evaluate adverse events. (Phase I/II) II. To evaluate overall response rate (ORR), clinical benefit rate (CBR), and duration of response (DOR). (Phase I/II) III. To evaluate time to progression (TTP) and overall survival (OS). (Phase I/II)

EXPLORATORY OBJECTIVES:

I. To evaluate PFS and secondary endpoints within patients crossing over to MLN0128 (TAK-228), upon disease progression during treatment with pazopanib. (Phase II) II. To evaluate the 4 month CBR observed within patients treated with MLN0128 (TAK-228) and grouped by histologically defined cohorts. (Phase II)

OUTLINE: This is a phase I, dose-escalation study, followed by a randomized phase II study.

PHASE I: Patients receive sapanisertib orally (PO) on days 1, 8, 15, and 22 in the absence of disease progression or unacceptable toxicity.

PHASE II: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive sapanisertib as in Phase I. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive pazopanib hydrochloride PO once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression may crossover to Arm I.

After completion of study treatment, patients are followed up at 4 weeks and then every 6 months for 2 years.

Outcome Measures

Primary Outcome Measures :

1. Maximum tolerated dose of sapanisertib (Phase I) [ Time Frame: 28 days ]
   Defined as the dose level below the lowest dose that induces dose-limiting toxicity in at least one-third of patients (at least 2 of a maximum of 6 new patients).
2. Progression-free survival (PFS) (Phase II) [ Time Frame: Up to 2 years ]
   Defined as either disease progression or death (in cases where patients have died without evidence of disease progression).

Secondary Outcome Measures :

1. Incidence of adverse events [ Time Frame: Up to 30 days after completion of study treatment ]
   Will be graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (version 5.0 beginning April 1, 2018). Adverse events will be summarized by dose cohorts and treatment arm. Summary statistics (e.g., mean, median, standard deviation) and frequency tables will be used to describe the distributions of adverse events. Rates of adverse events occurring in the sapanisertib arm will be compared to the pazopanib hydrochloride arm with chi-squared tests (or suitable alternative) used for comparisons where applicable. Adverse event analyses will separate events associated with the original treatment assignments from those having occurred after crossing over to receive sapanisertib at disease progression.
2. Tumor response (complete response [CR], partial response [PR], stable disease [SD], and progressive disease [PD]) [ Time Frame: Up to 2 years ]
   The frequencies and rates of tumor response categories (CR, PR, SD, PD, and too early/not evaluated) will be summarized by dose cohort and treatment arm, and Fisher's Exact test or applicable statistical tests will be used to compare the association of objective response rate (ORR, a tumor response of either CR or PR) and treatment.
3. Duration of response [ Time Frame: Time between each patient's best tumor response and progression (or date of last disease assessment for patients who die without progression or are lost to follow-up), assessed up to 2 years ]
   Will be analyzed using Kaplan-Meier methodology.
4. Clinical benefit rate (CBR) [ Time Frame: Up to 2 years ]
   Will be defined as the number of patients having either complete response (CR), partial response (PR), or stable disease for at least 6 months after starting treatment. The frequencies and rates of tumor response categories (CR, PR, SD, PD, and too early/not evaluated) will be summarized by dose cohort and treatment arm, and Fisher's Exact test or applicable statistical tests will be used to compare the association of objective response rate (ORR, a tumor response of either CR or PR) and treatment.
5. Time to progression (TTP) [ Time Frame: Time between randomization and disease progression, assessed up to 2 years ]
   Kaplan-Meier methodology will be used to estimate the distribution of TTP.
6. Overall survival (OS) [ Time Frame: Time between randomization and death due to any cause (or last contact for surviving patients and those lost to follow-up), assessed up to 2 years ]
   Kaplan-Meier methodology will be used to estimate the distribution of OS.

Other Outcome Measures:

1. Progression-free survival (PFS) (Phase II) [ Time Frame: Up to 2 years ]
   Defined as either disease progression or death (in cases where patients have died without evidence of disease progression) in crossover patients.
2. Duration of response in crossover patients (Phase II) [ Time Frame: Time between each patient's best tumor response and progression (or date of last disease assessment for patients who die without progression or are lost to follow-up), assessed up to 2 years ]
   Will be analyzed using Kaplan-Meier methodology.
3. Time to progression (TTP) in crossover patients (Phase II) [ Time Frame: Time between date the patient initiated sapanisertib and disease progression, assessed up to 2 years ]
   Kaplan-Meier methodology will be used to estimate the distribution of TTP.
4. Overall survival (OS) in crossover patients (Phase II) [ Time Frame: Time between date the patient initiated sapanisertib and death due to any cause (or last contact for surviving patients and those lost to follow-up), assessed up to 2 years ]
   Kaplan-Meier methodology will be used to estimate the distribution of OS.
5. Cohort-specific evaluation of 4-month clinical benefit rate (CBR) (Phase II, Analysis Group II) [ Time Frame: 4 months ]
   Analyses will be exploratory in nature.
