HB05P on Muscle Health

Официальное название

The Effect of HB05P Supplementatioon on Muscle Strength Improvement: A Randomized, Double-blind, Controlled Preliminary Clinical Trial (HB05P-Muscle Trial)

Обзор

The purpose of this pilot study is to evaluate whether HB05P, a health functional food ingredient containing pasteurized Akkermansia muciniphila HB05, improves muscle strength, and to evaluate its safety. This is a randomized, double-blind, placebo-controlled, parallel-group, single-center study. A total of 80 adults aged 50 to under 80 years who meet the 2025 Asian Working Group for Sarcopenia (AWGS) criteria for sarcopenia or possible sarcopenia will be randomly assigned in a 1:1 ratio to the test group or the control group. Participants will take one 430 mg hard capsule once daily with water after breakfast for 168 days (24 weeks). The test capsule contains 150 mg of HB05P (3 x 10\^10 cells per day); the control capsule contains microcrystalline cellulose and is identical in appearance and packaging. All participants are asked to perform 30 to 60 minutes of walking and resistance exercise at least 3 times per week throughout the study and to keep an exercise diary and an intake diary. The primary outcome is the change from baseline in peak torque per body weight (Nm/kg) of the quadriceps and hamstrings, measured with an isokinetic dynamometer at an angular velocity of 60 degrees per second and averaged across the left and right sides. Secondary outcomes include muscle power, muscle mass measured by dual-energy X-ray absorptiometry, handgrip strength, Short Physical Performance Battery scores, muscle-related blood markers, and quality of life. Efficacy and safety are assessed at Day 0, Day 84, and Day 168.

Подробное описание

Study design This is a randomized, double-blind, placebo (comparator food)-controlled, parallel-group, single-center exploratory (pilot) clinical trial of a health functional food ingredient. Eligible participants who provide written informed consent are randomly assigned 1:1 to the test group or the control group.

Sample size 64 participants (32 per group) are required for efficacy evaluation. Allowing for a 20 percent dropout rate, 80 participants (40 per group) will be enrolled.

Study population Adults aged 50 to under 80 years who meet the 2025 AWGS criteria for sarcopenia or possible sarcopenia. Muscle mass is assessed as ASM/height\^2 by bioelectrical impedance analysis, handgrip strength as the maximum value of the dominant hand, and physical performance by the 5-time chair stand test of the Short Physical Performance Battery.

Investigational products Test food: one hard capsule of 430 mg containing 150 mg HB05P (pasteurized Akkermansia muciniphila HB05), microcrystalline cellulose, silicon dioxide, and magnesium stearate. Control food: one hard capsule of 430 mg containing microcrystalline cellulose, silicon dioxide, and magnesium stearate, without HB05P. Both capsules are manufactured to be indistinguishable in internal and external appearance and are supplied in identical packaging.

Dosing One capsule once daily with water after breakfast for 168 days (24 weeks). Study food is dispensed at Visit 2 and Visit 3, 92 capsules at each visit. Intake is recorded by the participant in an intake diary, and compliance is checked at Visit 3 and Visit 4.

Blinding Randomization code assignment is kept sealed by the principal investigator and is not disclosed until the end of the study. If emergency unblinding is required for a serious adverse reaction, only the assignment of the individual participant can be opened, using participant-specific sealed envelopes. The randomization code is opened for efficacy analysis after study completion.

Visit schedule Visit 1, screening, Day -14 to Day 0: informed consent, eligibility assessment, demographics, medical and medication history, physical examination, eligibility tests, vital signs, clinical laboratory tests.

Visit 2, baseline, Day 0: eligibility assessment, physical examination, clinical laboratory tests, efficacy assessments, questionnaires, concomitant medication check, dispensing of study food.

Visit 3, Day 84 plus or minus 8 days: physical examination, vital signs, clinical laboratory tests, efficacy assessments, questionnaires, adverse event check, concomitant medication check, compliance check, dispensing of study food.

Visit 4, Day 168 plus or minus 8 days: physical examination, vital signs, clinical laboratory tests, efficacy assessments, questionnaires, adverse event check, concomitant medication check, compliance check.

Efficacy assessments (Visit 2, Visit 3, Visit 4) Isokinetic dynamometry at 60 degrees per second: peak torque per body weight of the quadriceps and hamstrings (average, left, right), average power (average, left, right), and muscle strength (left, right). Dual-energy X-ray absorptiometry: absolute skeletal muscle mass, ASM/height\^2, ASM/weight x 100, skeletal muscle mass/height\^2, lower-limb muscle mass, and body fat percentage (total, trunk). Handgrip strength (left, right). Short Physical Performance Battery total score and subscores. Blood markers: creatinine, total protein, albumin, prealbumin, C-reactive protein, creatine kinase, insulin-like growth factor 1, follistatin, and myostatin. Quality of life by EQ-5D-5L, a 24-hour dietary recall, and an exercise diary.

Safety assessments Adverse events, vital signs, physical examination, and clinical laboratory tests are collected at the scheduled visits and evaluated for severity and causal relationship to the study food.

Concomitant exercise All participants perform walking and resistance exercise for 30 to 60 minutes at least 3 times per week until the end of the study and record it in an exercise diary.
