Oral Supplementation With 1 mg of KGA-10 Daily (a Novel Environmentally-derived Mycolicibacterium) for Stress, Sleep, and Inflammation

21. maj 2026 opdateret af: Kioga Inc.

Clinical Trial of Oral Supplementation With Novel Mycolicibacterium (MTC 0012)

The goal of this clinical trial is to learn if a novel strain of heat-killed Mycolicibacterium that is being considered by the International Code of Nomenclature of Prokaryotes (ICNP) as candidate species and type strain "Candidatus Mycolicibacterium petrae" KGA-10 (KGA-10) has effects on perceived stress, systemic inflammation, self-reported measures of sleep, and self-reported general well-being in healthy adults. This clinical trial will also learn about safety and tolerability of KGA-10. This novel Mycolicibacterium species is also referred to as NeuroAlly and MTC 0012. The questions it aims to answer are: 1) is KGA-10 associated with adverse side effects; 2) does KGA-10 reduce systemic inflammation; 3) does KGA-10 reduce perceived stress; 4) does KGA-10 improve self -reported measures of sleep; 4) does KGA-10 improve self-reported metrics of general wellbeing.

Researchers will compare daily KGA-10 (1 mg mixed with microcrystalline cellulose in capsule form) to a placebo (microcrystalline cellulose in capsule form, but contains no KGA-10) to see if KGA-10 has effects on the proposed outcomes.

Participants will take KGA-10 or a placebo everyday for 8 weeks and keep a daily log of their supplement intake that includes the time of day. Participants will complete a weekly survey to assess side effects experienced during the trial both related and not related to the supplement. They will complete additional weekly surveys evaluating perceived stress and self-reported measures of sleep. They will complete a survey evaluating self-reported general well-being and provide dried blood spot (DBS) samples to assess systemic inflammation at baseline, week-4, and week-8

Intervention / Behandling
Eksperimentel: KGA-10
1 mg of KGA-10 mixed with microcrystalline cellulose in size 1 capsule
Kosttilskud: Mycolicibacterium petrae KGA-10 (heat-killed)
Heat-killed bacteria are considered postbiotics. At the time of registering this clinical trial, Mycolicibacterium petrae KGA-10 is being consider by the International Code of Nomenclature of Prokaryotes (ICNP) as candidate species and type strain therefore the proper nomenclature is "Candidatus Mycolicibacterium petrae" KGA-10.
