Novel Energy Metabolic Signaling Molecule With Therapeutic Potential
- Registration Number
- NCT04713319
- Lead Sponsor
- Petteri Hirvonen
- Brief Summary
Altogether a 25-day study. First 4 days non-blinded with water before 0-control blood samples (Day0). Thereafter blinded for 21 days (3 weeks). Study group was apparently healthy 50-60 -year-old males and females (N=27).
- Detailed Description
Blinded 21-day period was divided into two sub-periods (7 days and 14 days) and it included 3 measurement days. All measurements were on the same day of each week to facilitate maximal comparability (Day0, Day7 and Day21). Additionally on Day0 and Day7 there were acute measurements 45 minutes after morning "non-acute" resting and fasting blood samples. (In a "non-acute" measurement last dose of Panavital or placebo was taken 12 hours before the "non-acute" blood sample collected next morning .)
First week started with Day0 baseline measurements and immediately thereafter a strenuous VO2max test with 2 recovery days thereafter. After full recovery a 4-day blinded Panavital regimen. Last "non-acute" dose on Day6 was taken 12 hours before Day7 morning blood sample. At Day7 an acute 45 min placebo comparison was conducted.
Thereafter a 14-day follow-up period with halved Panavital dose or Placebo. Altogether 5 arterial blood samples were withdrawn. Three fasting and resting "non-acute" samples were taken in the morning before any treatments at Day0, Day7 and Day21. Two acute samples were collected after the VO2max (Day1) and after acute Panavital or placebo doses (Day7).
Additionally 5 fingertip blood samples for glucose (and lactate) were taken at the same time as arterial samples (Day0 and Day7) and one fingertip sample was taken immediately at the end of VO2max.

- Arm && Interventions
Group Intervention Description RH013001 (DGA) Panavital D-glyceric acid (DGA) calcium salt dehydrate (RH013001) dissolved into 1.8 dl of water. Effective dose of DGA was 3.33 mg / kg body weigh for the first 4 days. Thereafter the dose was reduced to half for the 14 days follow up period. Frequency: 2 times a day. Placebo Placebo Ten participants were randomly selected to the placebo group. Calcium chloride (E509) dissolved into water. Extremely small equimolar calcium dose with the test item.
- Primary Outcome Measures
Name Time Method Acute change in blood IL-6, insulin, and glucose after RH013001 or Placebo dose at Day7 45 minutes control blood sample Immediately after morning (non-acute) blood sample therapeutic dose of RH013001 or placebo. Comparison of average response between RH013001 and placebo. Additional comparison to VO2max response (see pre-specified outcome below).
Change in blood metrices from Day1 (0-control / baseline) to Day7 7 days Last dose 12 hours earlier = "non-acute". Paired comparison to Day1, measurements included energy metabolic and anti-inflammatory markers (first 3 days for recovery from VO2max), N in blinded placebo group was 0 for the first 7 days
- Secondary Outcome Measures
Name Time Method Global RNA-sequencing 21 days From 3 "non-acute" blood samples (Day1, Day7 and Day21) white blood cells collected into Paxgene tubes.
Change in "non-acute" blood sample metrices from Day1 (baseline) to Day21 21 days Intra-group paired comparison to Day1 (paired t-test of the group averages), unpaired comparison of changes in group averages between placebo and RH013001 treatment.
