A Phase 2, Randomized, Single-Blind, Active-Control, Parallel Group Study to Evaluate Safety and Activity of a Single Administration of F14 for Management of Postoperative Pain in Participants Undergoing Unilateral Total Knee Replacement

The safety and activity of a single, 3.5 mL dose of F14 (celecoxib) concurrent with standard
of care analgesia administered following total knee replacement will be compared to standard
of care analgesia alone.

This is a randomized, single-blind, active control study in participants undergoing primary
unilateral total knee replacement (TKR). Fifty (50) participants will be randomized 1:1 to
receive either a single, 3.5 mL dose of F14 (celecoxib) concurrent with standard of care
analgesia, or only standard of care analgesia. F14 will be administered into the joint space
at the end of surgery and just prior to wound closing. Safety will be evaluated through
recording of adverse events, vital signs, ECG, physical and knee-specific examinations,
laboratory blood tests and standing x-rays of the TKR obtained at 3 and 12 months.
Post-operative pain will be assessed using visual analog scores (VAS) and Western Ontario and
McMaster Universities Osteoarthritis Index (WOMAC) questionnaires and the Timed Up and Go
test. Concomitant medication usage including MSO4 equivalents will be monitored daily for 3
months with participant drug diaries, and at the 12-month visit. Perceived benefit of
analgesia will be compared using the Overall Benefit of Analgesic Score (OBAS). The
pharmacokinetic profile of celecoxib in plasma will be assessed up to 3 months. Standardized
physical therapy will be implemented post-operatively. Follow-up study visits will occur at
1, 2, 3, 4 (phone) and 6 weeks, 3 and 12 months.

Inclusion Criteria:

- Male and/or female indicated for primary, unilateral TKR

- Between 45-80 years of age inclusive at the time of signing the informed consent

- Capable of giving signed informed consent and complying with requirements and
restrictions listed in the informed consent form (ICF) and in this protocol

- Body Mass Index (BMI) ≤ 40 kg/m²

- Medically stable as determined by the Investigator based on pre-study medical history,
physical examination, clinical laboratory tests, and 12-lead electrocardiogram (ECG)
findings

- Absence of fixed flexion deformity exceeding 15°

- Absence of varus or valgus deformity exceeding 15°

- Minimum pre-operative flexion arc of 100°

- Absence of steroid, hyaluronic acid, platelet rich plasma, or any other type of
therapeutic injection(s) in the index knee within 3 months before scheduled surgery

- American Society of Anesthesiologists Physical Status Classification System (ASA-PSC)
score ≤ 3

- Females of childbearing potential with a negative pregnancy test at screening, who
agree to employ adequate birth control measures for the full duration of the study

- Has undergone scheduled total knee replacement surgery of the index knee, which in the
opinion of the Investigator, will not affect the participant's study follow-up

Exclusion Criteria:

- Allergy or hypersensitivity to active ingredient celecoxib. When an allergy to
celecoxib is unknown,allergy or hypersensitivity to sulfonamide antibiotics or sulfa
containing drugs

- Active or past infection in the index knee

- Previous total or partial knee arthroplasty in either knee within the past 6 months

- Prior arthroscopy in the index knee in the last 6 months; knee surgery other than
arthroscopy (including cruciate ligament, cartilage or osteotomy) in the index knee in
the last 12 months; knee surgery in the contralateral knee in the last 12 months
(excluding total or partial knee replacement)

- Documented osteonecrosis or arthrotomy within previous 12 months

- Prior or current presence of hardware in index knee other than screws from previous
ligament repair that do not require manipulation or removal for TKR surgery

- Other planned major surgery within 12 months of scheduled surgery

- Concurrent painful physical condition that may require analgesic treatment (such as an
NSAID or opioid) in the postsurgical period for pain that is not strictly related to
the TKR surgery emanating from other lower body joints in the ipsilateral (hip, ankle)
or contralateral (hip, knee, ankle) or back (by body diagram)

- Current or historical evidence of any clinically significant disease or condition,
especially cardiovascular, pulmonary or neurological conditions that, in the opinion
of the Investigator, may increase the risk of surgery or complicate or affect the
participant's study follow-up

- Strong narcotic use (e.g. Oxycontin®, Vicodin®, Percocet®) before scheduled study
surgery for a prolonged period exceeding 30 days within the last 2 years

- History of alcohol abuse within previous 12 months (score of 4 on CAGE questionnaire)

- Known or suspected history of illicit drug abuse within 1 year before randomization,
or history of opioid dependence within 2 years before scheduled surgery (score
exceeding 5 on DAST-10 questionnaire)

- Participation in another clinical study involving an investigational product (IP) or
device within 30 days before screening or scheduled participation in another clinical
study involving an IP or device during the course of this study

- Use of pregabalin or gabapentin, or other drugs for neuropathic pain unless willing to
discontinue at least 7 days prior to study surgery

- Current patient-reported seizure disorder

- Current peripheral neuropathy

- Current depression, mood or anxiety disorder (score exceeding 14 on PHQ-9
questionnaire)

- History of complex regional pain syndrome (CRPS)

- Diagnosis of clinically significant liver and/or renal abnormalities within previous 2
years

- Diagnosis of diabetes with HbA1c exceeding 7

- Current inflammatory arthritides (e.g., rheumatoid arthritis, lupus erythematosus,
ankylosing spondylitis, psoriatic arthritis), or traumatic bone injuries within 12
months before scheduled surgery, but excepting clinically stable/non-active gout that
does not affect the knee and does not interfere with walking

- Treatment with immunosuppressants, antipsychotics, anticholinergics, or
anticonvulsants within 1 month of randomization

- Diagnosis of skin disorders including psoriasis, vascular insufficiency ulcers, and
chronic venous stasis

- Participants with sleep apnea associated with a history of postoperative delirium. If
symptomatic sleep apnea is currently treated with continuous positive airway pressure
(CPAP) or bilevel positive airway pressure (BIPAP), use must be continued
postoperatively

- History of coronary or vascular stent placed within 3 months (may be extended to 1
year if medically indicated per physician discretion).

- Participation in active or pending personal injury or workers' compensation litigation
related to index knee

- Current or planned use of medical marijuana or cannabidiol (CBD), unless willing to
discontinue at least 10 days prior to study surgery and for 3 months following study
surgery

- Unwilling or unable to discontinue use of NSAIDs within 7 days of scheduled surgery
and for 3 months following study surgery, including low-dose aspirin for cardiac
prophylaxis
