TLC Announces Full Enrollment in Part 1 of Phase II Trial of TLC590 for Postsurgical Pain Management following Bunionectomy

SOUTH SAN FRANCISCO, Calif. and TAIPEI, Taiwan, April 08, 2019 (GLOBE NEWSWIRE) -- TLC TLC TWO: 4152))), a clinical-stage specialty pharmaceutical company dedicated to the development and commercialization of novel nanomedicines designed to target areas of unmet medical need in osteoarthritis, pain management, ophthalmology and oncology, today announced the earlier-than-scheduled full enrollment in Part 1 of TLC590's Phase II clinical trial in patients following bunionectomy. TLC590 is a proprietary BioSeizer^® liposomal formulation of ropivacaine engineered to provide fast and sustained postsurgical pain relief for up to 96 hours. Results from Part 1 of the Phase II clinical trial are expected in mid-2019.

"We are happy with the speedy recruitment and timely dosing of all patients, which took a mere four weeks. Once all patients have reached the end of study, which is scheduled to occur next month, database lock will take place and data will be un-blinded and analyzed. We anticipate results from this interim analysis to be available by mid-2019," said TLC President George Yeh. "We are eager to see how TLC590 will perform versus ropivacaine in an orthopedic setting, so that we can understand its pharmacokinetics in hard tissue surgeries as opposed to soft tissue surgeries, which was the focus of our recently completed – and successful – Phase I/II clinical trial in hernia repair surgery."

Part 1 of the Phase II trial took place at sites in California and Utah. 50 patients were randomized to receive TLC590 152mg, TLC590 190mg, TLC590 228mg, or ropivacaine 50mg following bunion removal surgery. The interim analysis will review the safety, efficacy and pharmacokinetics of the three doses of TLC590 and ropivacaine. Based on the analysis, the best dose(s) of TLC590 will be selected for further investigation in Part 2, which will include both ropivacaine and saline placebo as comparators.

About TLC590

TLC590 is a non-opioid BioSeizer^® sustained release formulation of ropivacaine. TLC590 is designed to prolong the retention time of the ropivacaine around the injection site as a drug depot, to simultaneously extend its therapeutic period, and to reduce unwanted systemic exposure. In a Phase I/II clinical trial in hernia repair surgery, TLC590 demonstrated durable, statistically significant and clinically meaningful improvement over the standard of care through 96 hours. 58.3% of patients who received TLC590 did not use any rescue opioids at all through the duration of the study; among those who did use rescue opioids, time to first postsurgical opioid use was about four times that of the ropivacaine group (standard of care), and mean total opioid consumption was 54% less through 96 hours post-surgery. A Phase II clinical trial is ongoing, with results from Part 1 expected in mid-2019.
