Efficacy and Safety of CKDB-322, a Combination of Lactiplantibacillus plantarum Q180 and Phaeodactylum tricornutum, for Reducing Body Fat and Abdominal Adiposity in Overweight Adults.
CKDB-322, a combination of Lactiplantibacillus plantarum Q180 and Phaeodactylum tricornutum, demonstrated statistically significant improvements in multiple adiposity-related outcomes including reductions in body fat mass, abdominal adiposity, and key anthropometric measures in overweight adults over 12 weeks.
Key Findings
Results
CKDB-322 supplementation produced statistically significant reductions in body fat mass and body fat percentage compared to placebo as measured by DEXA.
Randomized, double-blind, placebo-controlled trial design over 12 weeks
CKDB-322 group (n = 50) received 1.0 × 10^9 CFU of L. plantarum Q180 and 200 mg of P. tricornutum daily
Placebo group consisted of n = 50 participants
Reductions in body fat mass and body fat percentage were statistically significant (p < 0.05)
Body fat was measured using dual-energy X-ray absorptiometry (DEXA)
Results
CT analyses revealed significant reductions in abdominal fat area in the CKDB-322 group compared to placebo.
Abdominal fat area was assessed using computed tomography (CT)
Reductions in abdominal fat area reached statistical significance (p < 0.05)
Participants were required to have a waist circumference of ≥90 cm for men or ≥85 cm for women at enrollment
Results
Additional improvements in body weight and anthropometric parameters were observed in the CKDB-322 group.
Participants were aged 19–65 years with a BMI of 25–30 kg/m²
Body weight and anthropometric measures showed improvements in the CKDB-322 group
These changes were described as statistically significant improvements in 'multiple adiposity-related outcomes'
Results
Serum triglycerides and leptin levels decreased significantly in the CKDB-322 group compared to placebo.
Metabolic biomarker analyses included serum triglycerides and leptin
Both triglycerides and leptin reductions were statistically significant compared to the placebo group
These findings suggest modulation of metabolic pathways associated with adiposity
Results
Exploratory microbiome analyses indicated an increase in the relative abundance of Lactobacillus in the CKDB-322 group, suggesting potential modulation of the gut-adipose axis.
Gut microbiome composition was assessed as an exploratory outcome
Increased relative abundance of Lactobacillus was observed in the CKDB-322 group
Authors interpreted this finding as suggesting 'potential modulation of the gut-adipose axis'
These analyses were described as exploratory rather than primary endpoints
Results
CKDB-322 was well tolerated with no clinically significant adverse events or laboratory abnormalities over the 12-week trial.
Safety was evaluated throughout the 12-week intervention period
No clinically significant adverse events were reported
No laboratory abnormalities were identified
CKDB-322 was described as demonstrating 'a favorable safety profile'
