Trial Outcomes & Findings for A Study of Unesbulin in Participants With Advanced Leiomyosarcoma (LMS) (NCT NCT05269355)

NCT ID: NCT05269355

Last Updated: 2025-06-13

Results Overview

PFS was defined as the time from randomization to the documented disease progression or death due to any cause, whichever occurred first. Disease progression was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm). The appearance of one or more new lesions was also considered progression.

Unesbulin and Dacarbazine
Participants received unesbulin 300 milligrams (mg) tablets administered orally twice weekly in each 3-week treatment cycle in combination with dacarbazine 1000 mg/square meter (m\^2) intravenously (IV) once every 21 days. Treatment was continued for each participant until evidence of unacceptable toxicity, disease progression, or treatment discontinuation for another reason.

PRIMARY outcome

Timeframe: Up to approximately 2 years

Population: The modified intent-to-treat (mITT) set included randomized participants with 1 to 3 prior lines of therapy.

PFS was defined as the time from randomization to the documented disease progression or death due to any cause, whichever occurred first. Disease progression was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm). The appearance of one or more new lesions was also considered progression.

Timeframe: Up to approximately 2 years

Population: The mITT set included randomized participants with 1 to 3 prior lines of therapy.

ORR was defined as percentage of participants who achieved a confirmed best overall response (BOR) of complete response (CR) or partial response (PR). CR: Disappearance of all target lesions.

DCR was defined as percentage of participants who achieved a confirmed BOR of CR, PR, or at least 3 months of stable disease (SD). CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Disease progression: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression.

SECONDARY outcome

Timeframe: From first dose of study drug up to approximately 2 years

Population: The safety analysis set included all participants who received at least 1 dose of study drug (unesbulin/placebo or dacarbazine).

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. A TEAE was defined as an AE that had an onset date on or after the first dose of study drug until 30 days after last dose or occurred prior to first dose of study drug and worsened in severity after first dose of study drug. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'.
