Trial Outcomes & Findings for A Study of Tasisulam in Treating Participants With Malignant Melanoma (NCT NCT00383292)

NCT ID: NCT00383292

Last Updated: 2018-06-06

Results Overview

Participants achieved an objective response if they had a best overall response of complete response (CR) or partial response (PR). According to Response Evaluation Criteria in Solid Tumors v1.1 (RECIST v1.1), CR was the disappearance of all non-nodal target lesions, with the short axes of any target lymph node reduced to \<10 mm, the disappearance of all non-target lesions, and the normalization of tumor marker levels (if tumor markers were initially above the upper limit of normal); PR was defined as at least a 30% decrease in the sum of the diameters of target lesions (including the short axes of any target lymph node), taking as reference the baseline sum diameter. For each participant who is not known to have died or to have had objective progression of disease as of the data-inclusion cut-off date for a particular analysis, duration of tumor response was to be censored at the date of the participant's last objective tumor assessment prior to that cut-off date.

PRIMARY outcome

Timeframe: Baseline to Measured Progressive Disease (up to 60 Months)

Population: All participants who received at least one dose of study drug.

Participants achieved an objective response if they had a best overall response of complete response (CR) or partial response (PR). According to Response Evaluation Criteria in Solid Tumors v1.1 (RECIST v1.1), CR was the disappearance of all non-nodal target lesions, with the short axes of any target lymph node reduced to \<10 mm, the disappearance of all non-target lesions, and the normalization of tumor marker levels (if tumor markers were initially above the upper limit of normal); PR was defined as at least a 30% decrease in the sum of the diameters of target lesions (including the short axes of any target lymph node), taking as reference the baseline sum diameter. For each participant who is not known to have died or to have had objective progression of disease as of the data-inclusion cut-off date for a particular analysis, duration of tumor response was to be censored at the date of the participant's last objective tumor assessment prior to that cut-off date.

SECONDARY outcome

Timeframe: Baseline to Measured Progressive Disease or Death from Any Cause (up to 42 Months)

Population: All participants who received at least one dose of study drug. Participants censored: Tasisulam Target Cmax 420 µg/mL = 10, Tasisulam Target Cmax 360 µg/mL = 8, Albumin-Tailored Dose = 8.

PFS was defined as the time from baseline until measured PD or death from any cause, whichever is first. According to Response Evaluation Criteria in Solid Tumors v1.1 (RECIST v1.1), PD was at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. In addition to the 20% relative increase, the sum must have also demonstrated an absolute increase of at least 5 millimeters (mm). The appearance of 1 or more new lesions and/or unequivocal progression of existing nontarget lesions was also considered progression. Participants without objectively determined PD, who were alive at the end of the follow-up period (or lost to follow-up), were censored on the date of the participant's last complete radiographic tumor assessment; if no baseline or post-baseline radiologic assessment was available, the participant was censored at the date of randomization.

SECONDARY outcome

Timeframe: Baseline to Progressive Disease or Death Due to Any Cause (up to 60 Months)

Population: All participants who received at least one dose of study drug.

Participants achieved disease control if they had a best overall response of PR, CR or SD. According to RECIST v1.1, CR was the disappearance of all non-nodal target lesions, with the short axes of any target lymph node reduced to \<10 mm, the disappearance of all non-target lesions, and the normalization of tumor marker levels (if tumor markers were initially above the upper limit of normal \[ULN\]); PR was defined as at least a 30% decrease in the sum of the diameters of target lesions (including the short axes of any target lymph node), taking as reference the baseline sum diameter. SD was neither sufficient shrinkage to qualify as PR nor sufficient increase to qualify as PD, taking as reference the smallest sum diameter since treatment started. Clinical Response Rate was calculated as the number of participants who were free from progression (CR+PR+SD) for ≥2 cycles/number of participants who received at least 1 dose of tasisulam.

SD is measured at the start of the study drug until progressive disease or death due to any cause, whichever is first. Censoring occurred if a participant did not have a complete baseline disease assessment, initiated on another anti-cancer therapy (censored at the date of the last complete objective progression-free disease assessment before initiation of the new therapy), was not known to have died or had objective progression as of the data inclusion cutoff date for analysis.

Measure
Tasisulam Dose Target 420 μg/mL Cmax
n=68 participants at risk
Tasisulam loading dose targeting 420 μg/mL maximum concentration at the end of infusion (Cmax) administered as a 2-hour intravenous (IV) infusion on Day 1 of Cycle 1, followed by a chronic dose of 65% of the loading dose on Day 1 of subsequent 21-day cycles (every three weeks).
Tasisulam Dose Target 360 μg/mL Cmax
n=32 participants at risk
Tasisulam loading dose targeting 360 μg/mL Cmax was administered as a 2-hour IV infusion on Day 1 of Cycle 1, followed by a chronic dose of 90% of the loading dose on Day 1 of subsequent 21-day cycles (every three weeks).
Tasisulam Albumin-Tailored Dose
n=30 participants at risk
Tasisulam dose tailored to lean body weight (LBW) and pre-cycle albumin levels (≤420 μg/mL Cmax) was administered as a 2-hour IV infusion on Day 1 of Cycle 1, followed by chronic dosing ranging from 65% to 90% of the loading dose (tailored by the predose serum albumin for that cycle) on Day 1 of subsequent 28-day cycles (every four weeks).
