Outcome Measures

Primary Outcomes (1)

  • Numerical Pain Rating Scale (NPRS): Injection-site Pain

    Cohorts 2-4: Change in injection-site pain following intra-articular (IA) administration of CNTX-4975-05 (trans-capsaicin) scored using NPRS on a scale of 0 to 10 with 0 corresponding to no pain and 10 corresponding to the worst pain imaginable.

    Days 1 and 7

Secondary Outcomes (7)

  • IA Temperature

    Days 1 and 7

  • Numerical Pain Rating Scale (NPRS): Procedural Pain

    Days 1 and 7

  • Numerical Pain Rating Scale (NPRS): Procedural Pain

    Days 1 and 7

  • Numerical Pain Rating Scale (NPRS): Pain with Walking

    Screening through Day 42

  • Knee Injury and Osteoarthritis Outcome Score (KOOS)

    Screening through Day 42

  • +2 more secondary outcomes

Study Arms (4)

Cohort 1

EXPERIMENTAL

A comparison of two cooling methodologies in healthy volunteers after single intra-articular (IA) injection (15 mL) of 2% lidocaine (without epinephrine).

Other: Ice Pack and Cooling DeviceDrug: Capsaicin

Cohort 2

EXPERIMENTAL

Controlled cooling wrap versus ice pack cooling.

Drug: CNTX-4975-05 (trans-capsaicin)Drug: Capsaicin

Cohort 3

EXPERIMENTAL

Controlled cooling parameters will be determined after evaluation of data from prior cohorts.

Drug: CNTX-4975-05 (trans-capsaicin)Drug: Capsaicin

Cohort 4

EXPERIMENTAL

Controlled cooling with knee device versus no cooling (determined after evaluation of data from previous cohorts).

Drug: CNTX-4975-05 (trans-capsaicin)Drug: Capsaicin

Interventions

A comparison of two cooling methodologies in healthy volunteers after single intra-articular (IA) injection (15 mL) of 2% lidocaine (without epinephrine).

Cohort 1

Controlled cooling wrap vs ice pack cooling after single IA injection of 1 mg CNTX-4975-05 in each arm after single IA (15 mL) injection of 2% lidocaine (without epinephrine).

Cohort 2

Four intradermal injections of capsaicin, two on each forearm.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject is aged between 18 and 45 years, inclusive.
  • Subjects Body Mass Index (BMI) is between 18 and 32 kg/m\^2, inclusive and subject's weight is greater than or equal to 50 kg.
  • Subjects must be in good health, in the opinion of the Investigator, as determined by a medical history, physical examination, clinical laboratory tests, vital signs and 12 lead electrocardiogram (ECG).

You may not qualify if:

  • Subject has had a clinically significant illness that has not completely resolved in the four weeks before screening.
  • Subject has a history of neurological disorder which may impact the perception of pain or impairs the subject's ability to fully participate in the trial.
  • Subject is aged between 45 and 75 years, inclusive.
  • Subject's BMI is between 18 and 32 kg/m\^2, inclusive and subject's weight is greater than or equal to 50 kg.
  • Subject has a diagnosis of bilateral moderate to severe painful knee OA (subjects will be required to have a score on Pain with walking in the previous 24 hours, of 4 to 9, inclusive NPRS 0-10). The condition must be chronic with a history of painful arthritis for at least 3 months prior to entry in the study.
  • Subject has had a clinically significant illness, other than osteoarthritis, that has not completely resolved in the four weeks before screening.
  • Subject has a history of neurological disorder which may impact the perception of pain or impairs the subject's ability to fully participate in the trial.
  • Subject has used analgesic medications in the 2 days prior to dosing, except for paracetamol, as needed.
  • Subject has used topical medications applied to the knee for OA pain (including capsaicin, lidocaine, prescription or OTC medications) from 90 days prior to screening through to dosing.
  • Subject has been injected with corticosteroids in the knee 90 days prior to screening through to dosing.
  • Subject currently uses opioids for any condition other than OA knee pain (maximum dose 15 mg hydrocodone, or equivalent, per day prescribed by a physician).
