  1. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by renal (kidney) function - specific gravity

    Specific gravity will be measured via urinalysis with microscopy (unitless; ratio of urine density \[g/cm\^3\] divided by density of pure water).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  2. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by renal (kidney) function - pH

    pH will be measured via urinalysis with microscopy (usually presented unitless; moles H+ per liter).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  3. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by renal (kidney) function - microscopy

    Molecular concentrations in urine will be measured via urinalysis with microscopy. The following molecular concentrations will be measured: total protein, glucose, ketones, blood, bilirubin, and urobilinogen (all units: unitless).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  4. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by renal (kidney) function - BUN

    Blood urea nitrogen (BUN; units: mg/dL) will be measured using a blood sample.

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  5. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by renal (kidney) function - creatinine

    Creatinine will be measured using a blood sample. It will be used to estimate glomerular filtration rate (mL/min/m\^2 body surface area).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  6. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by hepatic (liver) function - enzymes

    Hepatic enzyme function will be measured with a blood sample. Outcomes include alkaline phosphatase \[ALP\], aspartate aminotransferase \[AST\], alanine aminotransferase \[ALT\] (all units: units per liter).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  7. Difference in the incidence of Treatment-Emergent Adverse Events with supplementation as assessed by hepatic (liver) function

    Hepatic function will be measured with a blood sample. Outcomes of interest include bilirubin, albumin, and total protein (all units: g/dL).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  8. Difference in the incidence of Treatment-Emergent Adverse Events before and after supplementation as assessed by adverse events form

    Adverse events will be recorded using the NIH's Adverse Events Form, ver 2.

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  9. Difference in the incidence of Treatment-Emergent Adverse Events before and after supplementation as assessed by checklist of changes to major organ systems

    Common complaints of major organ system experienced over the last 3 days will be self-reported as present or not present for: stomachache, nausea, dizziness, coughing, wheezing, chest pain, weakness, increased headache, negative mood, rash, dry scalp, dry skin, nail changes, ear pain, decreased memory, itching, swelling, diarrhea, stiff joints, nose bleeds, heart burn, numbness, nasal congestion, ringing in ears, increased stress, decreased libido, constipation, shortness of breath, loss of appetite, loss of energy, blood in urine, \& blood in stool.

  10. Ability to comply with HMB supplementation as assessed by a daily diary & compliance check-ins

    Participants will complete a daily paper or electronic diary to document taking their supplement. Compliance checks will be conducted by the study staff via a call or email. Unused supplements will be counted at the end of the study. Compliance will be calculated as a percent (# of pills taken on time/total # of pills that should have been taken) x 100.

    Time frame: Post-supplementation (12 wks)

  11. Ability to swallow HMB supplement as assessed by the PILL-5 survey

    The PILL-5 survey is a 5 question survey that measures physical (e.g., pill sticks in my throat) and emotional (e.g., I have a fear of swallowing pills) swallowing ability. It will be self-reported using a 5-pt Likert scale (never, almost never, sometimes, almost always, always). A total score is calculated (range 0-20, with 20 representing maximum pill dysphasia).

    Time frame: Week 1 of supplementation

  12. Palatability of HMB supplement as assessed by the visual 5 faces hedonic scale

    Whether participants like or dislike the taste of the supplement will be measured with a 5 faces hedonic scale with the numerical anchors ranging from 1 to 5 (best) and text anchors: dislike a lot; dislike a little; neither like nor dislike; like a little; like a lot.

    Time frame: Week 1 of supplementation

  13. Satisfaction of supplement dose volume as assessed by survey

    A question will measure if participants felt the dose volume (number of tablets) were acceptable (yes or no).

    Time frame: Week 12 of supplementation

  14. Difference in satisfaction of supplement dose frequency as assessed by survey

    A question will measure if participants felt the frequency (2 times per day) was acceptable (yes or no).

    Time frame: Week 12 of supplementation

Secondary outcomes

  1. Change in lower extremity strength with supplementation as assessed using a Biodex isokinetic system

    Isokinetic dynamometry will be used to measure peak torque of hip extensors \& flexors, knee extensors \& flexors, and ankle plantarflexors and dorsiflexors (Newton-meters/body mass).

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  2. Change in muscle mass with supplementation as assessed by dual-energy x-ray absorptiometry (DXA)

    Skeletal muscle mass (kg) will be measured using a whole body DXA scan.

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  3. Change in functional mobility with supplementation as assessed by the 10-meter walk test (10MWT)

    The 10MWT will be performed at the participant's fastest walking speed over a 14-m walkway, with 2-m on each end for acceleration and deceleration. Time to travel the middle 10-m will be recorded by stopwatch and average speed (m/s) calculated. Usual orthoses and assistive devices will be permitted and used at each repeat assessment.

    Time frame: Pre-supplementation (12 wks), post-supplementation (12 wks)

  4. Change in functional mobility with supplementation as assessed by the Timed-up-and-go test (TUG)

    The TUG will be performed at self-selected speed using a standard height chair with arms. Participants will stand up, walk 3-m, and return to their seat. Time (seconds) will be measured. Usual orthoses and assistive devices will be permitted and used at each repeat assessment.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2022 (actual). Primary completion is estimated for May 2024, 24 months after the start.

Of 902 non-industry interventional studies with no phase under Cerebral Palsy, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 31. This study's planned 24 months is above that.

Counting every sponsor, half of 921 studies reached it within 12 months; a quarter within 5 and three quarters within 31.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
