Registration Number
NCT02197572
Lead Sponsor

Brief Summary

The purpose of this study is to characterize the effect of a single dose of 40 mg sapanisertib (MLN0128) on the electrocardiographic QT/QTc interval in participants with advanced solid tumors.

Detailed Description

The drug being tested in this study is called sapanisertib (MLN0128). Sapanisertib is being tested to determine the effect of a single 40 mg dose on the electrocardiographic measure of the time between the start of the Q wave and the end of the T wave in the electrical cycle of the heart (QT)/rate corrected QT (QTc) interval in patients with advanced solid tumors. This study will look at electrocardiogram (ECG) results before and after a single dose of sapanisertib.

The study will enroll approximately 30 patients. All participants will receive a single 40 mg dose of sapanisertib capsules on Day 1. Participants may continue to receive sapanisertib for up to 1 year at a dose of up to 30 mg once weekly if a clinical benefit is being derived.

This multi-centre trial will be conducted in the United States. The overall time to participate in this study is up to 14 months. Participants will make 6 visits to the clinic and end of study visit 30 to 40 days after last dose of study drug for a follow-up assessment. Participants that continue treatment with sapanisertib will continue to make additional visits to the clinic once or twice every 4 weeks and the end of study visit 30 to 40 days after last dose of study drug for a follow-up assessment.

SapanisertibSapanisertibSapanisertib starting dose of 40 mg, capsules, orally, once, on Day 1, Cycle 1 (28 days cycle) followed by sapanisertib 30 mg, capsules, orally, once weekly (QW) starting on Cycle 1, Day 8 based on safety and tolerability and as per investigator's discretion up to disease progression, unacceptable sapanisertib-related toxicity, withdrawal of consent, or for up to 12 months (whichever occurred first).
Primary Outcome Measures
NameTimeMethod
Mean Change From Time-Matched Baseline in QTcI, Individual Baseline Corrected Rate-Corrected QT IntervalBaseline; Cycle 1 (28 days cycle): 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 24 and 48 hours postdose

The mean changes of QTcI from time-matched baseline was measured by electrocardiogram (ECG) to evaluate the potential effect of drug on QTc interval duration. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measures mixed effects linear model. A negative change from baseline indicates shortening and a positive change from baseline indicates prolongation of QTcI interval.

Secondary Outcome Measures
NameTimeMethod
Mean Change From Time-Matched Baseline in QTc With Rate-Corrected QT Interval With Bazett Correction (QTcB)Baseline; Cycle 1 (28 days cycle): 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 24 and 48 hours postdose

The mean changes of QTcB from time-matched baseline was measured by ECG to evaluate the potential effect of drug on QTc interval duration. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measures mixed effects linear model. A negative change from baseline indicates shortening and a positive change from baseline indicates prolongation of QTcB interval.

Change From Time-Matched Baseline in QRS IntervalBaseline; Cycle 1 (28 days cycle): 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 24 and 48 hours postdose

QRS interval is defined as the time between the start of the Q wave and end of the S wave on ECG. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measures mixed effects linear model. A negative change from baseline indicates shortening and a positive change from baseline indicates prolongation of QRS interval.

Number of Participants With Atleast One Adverse Event (AE) and Serious Adverse Event (SAE)From first dose of study drug through 30 days after the last dose of study drug (Up to 13 months)

An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. An SAE is any untoward medical occurrence that results in death; is life-threatening; requires inpatient hospitalization or prolongation of present hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect or is a medically important event that may not be immediately life-threatening or result in death or hospitalization, but may jeopardize the participant or may require intervention to prevent one of other outcomes listed in definition above, or involves suspected transmission via a medicinal product of an infectious agent.

Change From Time-Matched Baseline in Heart RateBaseline; Cycle 1 (28 days cycle): 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 24 and 48 hours postdose

Heart rate was assessed using the ECG. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measure mixed effects linear model. A negative change from baseline indicates decrease in heart rate.

Number of Participants With Potentially Clinically Significant Abnormal Laboratory Values Reported as AEFrom first dose of study drug through 30 days after the last dose of study drug (Up to 13 months)

The laboratory parameters included clinical chemistry, hematology, and urinalysis. Any abnormal change in the laboratory values were assessed by Investigator and reported as AE. An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (e.g., a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug.

Number of Participants With Potentially Clinically Significant Abnormal Vital Signs Reported as AEFrom first dose of study drug through 30 days after the last dose of study drug (Up to 13 months)

Vital sign measurements included blood pressure (diastolic and systolic), heart rate, and temperature. Any abnormal change in the vital sign values were assessed by Investigator and reported as AE. An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (e.g., a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug.

Mean Change From Time-Matched Baseline in QTc With Rate-Corrected QT Interval Fridericia Correction (QTcF)Baseline; Cycle 1 (28 days cycle): 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 24 and 48 hours postdose

The mean changes of QTcF from time-matched baseline was measured by ECG to evaluate the potential effect of drug on QTc interval duration. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measures mixed effects linear model. A negative change from baseline indicates shortening and a positive change from baseline indicates prolongation of QTcF interval.

Change From Time-Matched Baseline in PR IntervalBaseline; Cycle 1 (28 days cycle): 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 24 and 48 hours postdose

PR interval is defined as the time between the start of the P wave and the beginning of the QRS complex on ECG. Holter monitors were used to collect triplicate ECG measurements and were based on a repeated measures mixed effects linear model. A negative change from baseline indicates shortening and a positive change from baseline indicates prolongation of PR interval.
