Study Endpoints

Primary Endpoints

Change in Weekly Average Electronic Diary (eDiary) Numeric Rating Scale -Pain (NRS-Pain) Score From Randomization Baseline to Final 2 Weeks (Average of Weeks 11 and 12)
Weeks 11 and 12

Weekly average diary NRS-Pain scores were derived from the daily NRS-pain scale and calculated as the mean of the last 7 days. NRS-Pain scores based on an 11-point numerical rating scale from 0 (no pain) to 10 (worst possible pain). Higher scores indicate greater pain.

Frequently asked questions about ALO-02

What is ALO-02 used for?

ALO-02 is being developed for the management of moderate to severe chronic pain, including chronic low back pain. It is an investigational small molecule product studied in adults 18 years and older. It has not been approved for any indication and remains in clinical development.

Who makes ALO-02?

ALO-02 is developed by Pfizer, Inc., which trades on the New York Stock Exchange under the ticker PFE. Pfizer sponsored the clinical program evaluating the product in patients with moderate to severe chronic low back pain.

What phase is ALO-02 in?

ALO-02 has completed a Phase 3 clinical trial and is not currently listed with any active trials. The Phase 3 study was a randomized, double-blind, placebo-controlled trial in patients with moderate to severe chronic low back pain. ALO-02 is investigational and has not been approved by the FDA.

What clinical trials is ALO-02 in?

ALO-02 has been studied in two completed trials. The Phase 3 trial NCT01571362 enrolled 410 adults with moderate to severe chronic low back pain in the United States. The Phase 1 pharmacokinetics trial NCT01557257 compared ALO-02 with OxyContin in 13 healthy volunteers.

Is ALO-02 the same as Oxycodone Naltrexone?

Yes. ALO-02 is also known as oxycodone naltrexone, reflecting its composition of oxycodone hydrochloride and naltrexone hydrochloride. The Phase 3 trial title lists the drug as ALO-02 (oxycodone hydrochloride and naltrexone hydrochloride), so searches for either name refer to the same investigational product.
