About this trial

This is an interventional treatment trial for Knee Osteoarthritis focused on measuring Osteoarthritis, Knee

Eligibility Criteria

50 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria:

  • Body mass index (BMI) between 18.0-35.0 kg/m^2
  • Subject has moderate to severe painful osteoarthritis in one knee while walking (index knee); contralateral knee may or may not have osteoarthritis, pain should be none to mild in the non-index knee
  • Confirmation of the OA of the index knee: American College of Rheumatology (ACR) diagnostic criteria
  • Subject has intact skin at the location of the dosing sites (patch or injection)

Key Exclusion Criteria:

  • Subject has any other form of arthritis, such as, but not limited to, rheumatoid arthritis, psoriatic arthritis, gout, systemic lupus erythematosus, etc.
  • Subject has a dermatological condition that may contraindicate participation, including any compromise in skin integrity at the CNTX-4975-05 injection site or the Qutenza® skin application site, e.g., severe or cystic acne, psoriasis, eczema, atopic dermatitis, active or treated cancer, etc.

Outcomes

Primary Outcome Measures

Capsaicin Pharmacokinetics - AUC0-t
Single-dose systemic exposure to trans- and cis-capsaicin measured by AUC0-t.
Capsaicin Pharmacokinetics - AUC0-inf
Single-dose systemic exposure to trans- and cis-capsaicin measured by AUC0-inf.

Incidence of treatment-emergent adverse events (TEAEs) (safety and tolerability)
Number of participants with TEAEs, which includes laboratory test variables
IA knee Lidocaine Systemic Pharmacokinetics - Concentration
System exposure to lidocaine measured by plasma concentration
