Study Endpoints

Primary Endpoints

Mean Summed Pain Intensity (SPI) Score Over 24 Hours
0-24 hours

The SPI is derived by summing the pain intensity score weighted by the scheduled time duration. SPI0-24 will be calculated by summing the Pain intensity (PI) score at the relevant time points weighted by the scheduled time duration since the prior PI assessment as follows: SPI0-24= PI1+PI2+2\*PI4+2\*PI6+2\*PI8+2\*PI10+2\*PI12+2\*PI14+4\*PI18+6\*PI24. Min = 0 (if PI=0 at every time) and Max = 240 (if PI=10 at every time).

Frequently asked questions about HTX-011A

What is HTX-011A used for?

HTX-011A is an investigational small molecule being developed for postoperative pain. It is designed for local administration to provide analgesia following surgical procedures. In clinical trials, it has been evaluated for pain management after bunionectomy surgery. The drug is still in clinical development and has not been approved by regulatory authorities.

Who makes HTX-011A?

HTX-011A is being developed by Heron Therapeutics, Inc., a biopharmaceutical company. Heron Therapeutics is publicly traded under the ticker symbol HRTX. The company is conducting clinical trials to evaluate the safety and efficacy of HTX-011A for the management of postoperative pain.

What phase is HTX-011A in?

HTX-011A is currently in Phase 2 clinical development. It has completed one Phase 2 trial, which was a randomized, double-blind, active-controlled study. The drug is investigational and has not been approved by the FDA or any other regulatory agency. Further clinical development may be required before it can be considered for approval.

What clinical trials is HTX-011A in?

HTX-011A has been studied in one completed Phase 2 clinical trial with the identifier NCT02762929. This trial evaluated the efficacy and safety of locally administered HTX-011 for postoperative analgesia following bunionectomy. The study enrolled 430 participants in the United States and included adults aged 18 years and older.

Is HTX-011A the same as HTX-011?

HTX-011A is related to HTX-011, as the clinical trial for HTX-011A was conducted under the name HTX-011. The trial NCT02762929 evaluated HTX-011 for postoperative analgesia. HTX-011A appears to be an alternative designation for the same investigational drug candidate.
