A Double-blind, Placebo-controlled, Randomized INTerventional Clinical Trial (SARA-INT)

Phase 2

Completed

Conditions: Sarcopenia
Gait Disorders in Old Age
Muscle Weakness

Interventions: Drug: Placebo
Drug: BIO101

Registration Number: NCT03452488

Lead Sponsor: Biophytis

Brief Summary: The main objective of the study is to evaluate the effect of two daily doses of BIO101 versus placebo on mobility function as measured by gait speed using the 400MW test. The absolute change from baseline in meters/second observed in each treatment group at 6 Month was compared to the placebo group. Due to the Covid pandemic \>50% of data at endpoint was missing, which may have affected the ability of the study to deliver the expected results. Additionally, although the planned duration of treatment was 6 months, it was extended up to 9 months for some participants as a result of the pandemic.

Detailed Description: The aim of this phase 2 double-blind, placebo-controlled, randomized interventional clinical trial (SARA-INT) is to evaluate the safety and efficacy of BIO-101 175 mg b.i.d. and 350 mg b.i.d. 9 months oral administration to participants suffering from age-related sarcopenia, including sarcopenic obesity, aged ≥65 years and at risk of mobility disability. There are 3-arms (2 doses versus placebo). This comparative clinical trial evaluated the effects up to 9 month treatment duration, based on the hypothesis that physical function of sarcopenic, older participants with an initial degree of mobility disability (SPPB) may be improved by BIO101.

Included participants were randomized in a 1:1:1 ratio, to one of the 3 arms of treatment in a blinded manner. The randomization was stratified by gender and by center. Based on absence of long-term toxicology data, the investigational drug exposure was initially capped at 6 months.

Primary Outcome Measures

Name	Time	Method
Change From Baseline to 6 Months in Gait Speed for 400 Meter Walking (MW) Test	Baseline and 6 Months	Gait speed was measured using the 400 MW test, which measured how long it took the participant to walk a distance of 400 meters. Missing data imputed using adjusted Bayesian Multiple Imputation (MI) methods for Non-Completers who failed to perform the Test feasibility and Multiple Imputation for participants who without data on on-Site visit. Data up to 9 months was used where 6 months data were unavailable for participants enrolled during the COVID-19 pandemic.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline to 6 Months in Short Form-36 (SF-36) 10 Item Physical Function Domain (PF-10) Sub-score	Baseline and 6 Months	The Physical Function Domain (PF-10) of the SF-36 assesses an individual's perceived physical functioning and limitations in various activities. It consists of ten items that ask about a person's ability to perform different physical activities and tasks. Scores on the PF-10 range from 0 to 100 where 100 indicates no physical limitations. Missing data imputed using adjusted Bayesian MI methods. Data up to 9 month was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Handgrip Strength Test	Baseline and 6 Months	Handgrip strength was a commonly used measure of upper body skeletal muscle function and had been widely used as a general indicator of frailty with predictive validity for both mortality and functional limitations. Participants were instructed to stand upright and with the dynamometer beside them but not against their body. Strength was measured three times for both hands. The highest value of all 3 attempts was kept for further analysis. Grip strength was measured in the dominant hand using a hydraulic grip strength dynamometer. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Appendicular Lean Body Mass (ALM) Based on Dual-energy X-ray Absorptiometry (DEXA) Measurements	Baseline and 6 Months	DEXA scans provided accurate measurements of body composition, recording fat and lean mass distribution throughout the entire body. Foundation of National Health Institute (FNIH) project report recommended ALM alone was used to measure gender-specific low muscle mass. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Rate of Response for Completing 400 MW Test After 6 Months	Baseline and 6 Months	A responder was defined as an improvement (increase) of 0.1 m/s or more in 400MW gait speed test compared to baseline. A non-responder was defined as a participant that was not a responder. Participants with a missing value at the visit and/or missing baseline value were considered as non-responders. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Muscle Strength Based on Knee Extension	Baseline and 6 Months	Isometric knee extension torque was measured with a knee extension dynamometer chair. The participants were positioned in an upright position, with straps to affix the hips to the chair and the ankle to a force or torque transducer at the knee angle of 90°. Lever arm length was recorded as the distance between the knee axis of rotation and the middle of the pad. Knee extension was measured using the maximum peak torque measurement Newton meter (Nm) for 60°/s, 90°/s and 180°/s for the tested leg (either right or left). The Knee extension torque was obtained either directly or by multiplying recorded peak force with the lever arm length. The assay with the highest torque output was taken for analyses. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Time for Five Chair Stands as Part of the Short Physical Performance Battery (SPPB) Assessment	Baseline and 6 Months	The SPPB was a series of tests designed to examine physical movements. The chair stands tests involved standing from a chair a number of times to test leg strength. Each performance measures were assigned a score ranging from 0 to 4, with 4 indicating the highest level of performance and 0 the inability to complete the test. The time to complete the task was recorded. The time required to perform five chair stands was scored as follows: ≥ 16.70 sec = 1; 13.70 to 16.69 sec = 2; 11.20 to 13.69 sec = 3; ≤ 11.19 = 4. A score of 0 was assigned to participants unable to perform the task. A summary score ranging from 0 (worst performers) to 12 (best performers) was calculated by adding sub scores from the chair stands test. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Distance in the 6-Minute Walk Test (6MWT)	Baseline and 6 Months	The 6MWT was a test for functional exercise capacity and involved measuring the distance a participant could cover within the allotted time of 6 minutes. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Pepper Assessment Tool for Disability (PAT-D) for Obese Participants	Baseline and 6 Months	The PAT-D was a disability questionnaire which asked respondents how much difficulty they had with a range of activities with functioning. PAT-D scores range from 1 (worst) to 5 (best). Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in SPPB Total Score	Baseline and 6 Months	The SPPB was a series of tests designed to examine physical movements. Results of the SPPB included total gait speed score, total balance test score, and total chair stand score. The first tests examined balance (without the assistance of a cane or walker) with the feet in three different orientations, the second test examined gait speed, and the third tests involved standing from a Chair a number of times to test leg strength. A score of 0 was assigned to participants unable to perform the task. A summary score ranging from 0 (worst performers) to 12 (best performers) was calculated by adding sub scores from the walking speed, chair stands and balance tests. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Sarcopenia Quality of Life (SarQoL) Auto-Evaluation Questionnaire	Baseline and 6 Months	The SarQoL was a sarcopenia-specific, self-administered, quality of life questionnaire designed for community-dwelling elderly study participants aged 65 years and older. The questionnaire contained 22 questions, which took approximately 10 minutes to complete. The questionnaire covered 7 domains: physical and mental health; locomotion; body composition; functionality; activities of daily living; leisure activities; and fears. Most questions are answered on a 4 point Likert scale. The total scoring of the SarQoL questionnaire ranges from 0 (worst imaginable health) to 100 (best imaginable health). A higher score reflected a higher quality of life. Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
Change From Baseline to 6 Months in Stair Climb Power Test (SCPT)	Baseline and 6 Months	The SCPT measured the ability to ascend and descend stairs and tests lower body strength and balance and measures time (in seconds) taken to ascend and descend a flight of stairs (10 steps with a 20 cm step height; a handrail was recommended). Step heights should have been suitable (between 16 and 20 cm). Data up to month 9 was used where 6 month data were unavailable for participants enrolled during the COVID-19 pandemic.
