NCT07437547

Brief Summary

This randomized, double-blind, placebo-controlled Phase 2 study evaluates whether pentadecapeptide BPC 157 (BPC-157), an investigational peptide, can speed structural healing and functional recovery after an acute grade II hamstring muscle strain. Participants will receive BPC 157 or placebo for 14 days in addition to a standardized rehabilitation program. The co-primary endpoints are time to return to unrestricted sport and change in MRI-assessed injury volume at Day 14.

Outcome Measures

Primary Outcomes (2)

  • Time to return to unrestricted sport participation (days)

    defined as clearance by a blinded sports medicine clinician and completion of a standardized functional performance battery without pain-limited stopping.

    8 Weeks

  • Change from baseline to Day 14 in MRI-assessed hamstring injury volume (cm^3), measured by blinded central radiology review.

    14 Days

Secondary Outcomes (3)

  • Change in pain during activity on a 0-10 Numeric Rating Scale (NRS; 0 = no pain, 10 = worst pain).

    56 Days

  • Hamstring strength limb symmetry index (LSI) by isokinetic dynamometry

    56 Days

  • Change in Lower Extremity Functional Scale (LEFS; 0-80, higher scores indicate better function)

    56 Days

Study Arms (2)

EXPERIMENTAL

Participants receive investigational pentadecapeptide BPC 157 plus standardized rehabilitation.

Eligibility Criteria

Age18 Years - 45 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age 18 to 45 years.
  • Acute posterior thigh pain consistent with hamstring strain with onset within 72 hours prior to screening.
  • MRI-confirmed grade II hamstring strain of the biceps femoris, semitendinosus, or semimembranosus, with measurable lesion.
  • Pre-injury physical activity \>= 3 sessions/week or participation in organized recreational sport.
  • Willingness to follow the standardized rehabilitation protocol and attend all study visits.
  • For participants of childbearing potential: negative pregnancy test at baseline and agreement to use effective contraception during dosing and for 30 days after last dose.

You may not qualify if:

  • Grade III hamstring tear, tendon avulsion, or injury requiring surgical management.
  • Concomitant lower extremity injury that would interfere with rehabilitation or outcome assessment.
  • Prior hamstring strain on the index limb within the past 6 months.
  • Use of systemic corticosteroids, anabolic agents, platelet-rich plasma, stem-cell products, or investigational peptides/growth factors within 30 days prior to screening.
  • Known bleeding disorder or current therapeutic anticoagulation.
  • Significant uncontrolled medical illness (e.g., severe cardiovascular, hepatic, or renal disease) that increases study risk.
  • Known allergy or hypersensitivity to components of the investigational product or placebo.
  • Pregnant or breastfeeding.
  • Current participation in another interventional clinical study or participation within 30 days prior to screening.
  • Currently subject to a formal anti-doping testing program (e.g., WADA/USADA-aligned) where use of an investigational peptide could create a regulatory conflict, unless explicitly approved by the relevant authority
