Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This Phase 2 open-label trial investigates the pharmacokinetics (PK), pharmacodynamics, and safety profile of TLC590 across various surgical procedures. Researchers aim to determine the maximum tolerated dose (MTD) of TLC590 via Safety Monitoring Committee (SMC).

The study evaluates TLC590 in bunionectomy, laparoscopy-assisted open ventral hernia repair, breast augmentation, abdominoplasty, and total knee arthroplasty models. Additionally, it determines the relative bioavailability of TLC590 to ropivacaine injection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This Phase 2, open-label, multi-center study is a 3-part study to be performed in approximately 120 subjects undergoing multiple surgical procedures receiving TLC590 or ropivacaine injection. Subjects eligible based on inclusion and exclusion criteria will receive study drug administered via infiltration. Subjects entering all parts of the study will undergo the consent and screening procedures, eligibility requirements, and PK and safety evaluations during their participation in the study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Able and willing to provide written informed consent
2. Male or female aged 18 to 70 years, inclusive. For the Part 2 breast augmentation surgical model, only females can be enrolled
3. Scheduled to undergo one of the following elective surgeries, with no additional procedures and be able to use the anesthesia regimen:

1. Unilateral first metatarsal bunionectomy (Cohort 1)
2. Laparoscopy-assisted open ventral hernia repair (Cohort 2 and 6)
3. Breast augmentation (Cohort 3 through 5)
4. Unilateral total knee arthroplasty (Cohort 7)
5. Abdominoplasty (tummy tuck) (Cohort 8)
4. ASA Physical Status Classification of 1 or 2
5. Male subjects must be either biologically or surgically sterile or commit to the use of a reliable method of birth control (must agree to use double-barrier contraception in the event of sexual activity) or be practicing abstinence for the duration of the study and for 30 days after study drug administration
6. Female subjects are eligible only if all the following apply:

1. Not pregnant with a negative serum pregnancy test at Screening and negative urine pregnancy test on Day 1 before surgery (pregnancy test not required for females of non-childbearing potential, defined as surgically sterile or post-menopausal)
2. Not lactating
3. Not planning to become pregnant during the study
4. If of childbearing potential, commits to the use of a highly effective method of birth control for the duration of the study and or at least 30 days after study drug administration
7. BMI \>18 \~ ≤39 kg/m2

Exclusion Criteria

2. Evidence of a clinically significant 12-lead ECG
3. History of orthostatic hypotension, syncope, or other syncopal attacks
4. History or any clinical manifestation of significant renal, hepatic, gastrointestinal, cardiovascular, metabolic, neurologic, psychiatric, or other condition that has been assessed by the Investigator to be unsuitable for participation in the study
5. History of seizures or taking anticonvulsants during the Screening period

14. Pre-existing concurrent acute, or chronic painful restrictive/physical condition that may confound postoperative pain assessments or is expected to require analgesic treatment during the study
15. Has known or suspected daily use of opioids for longer than 4 days per week within the previous 6 months prior to Screening
16. Is taking daily analgesics for longer than 4 days per week for a chronically painful condition during the Screening period. Not exclusionary if it is utilized for pain related to the total knee arthroplasty indication
