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 an investigational small molecule being developed for the management of moderate to severe pain, including chronic low back pain. It has been studied in healthy volunteers for pharmacokinetic assessments. The drug is a combination of oxycodone hydrochloride and naltrexone hydrochloride in an extended release formulation.

Who makes ALO-02?

ALO-02 is being developed by Pfizer, Inc., a company traded on the New York Stock Exchange under the ticker symbol PFE. Pfizer has conducted clinical trials of ALO-02 in the United States for pain management indications.

What phase is ALO-02 in?

ALO-02 has completed a Phase 3 clinical trial for chronic low back pain. It is an investigational drug and remains in clinical development. The Phase 3 study evaluated the drug in patients with moderate to severe chronic low back pain.

What clinical trials is ALO-02 in?

ALO-02 has been studied in three completed clinical trials. NCT01456507 was a Phase 1 healthy volunteers study of food effects, NCT01557257 was a Phase 1 pharmacokinetics study versus OxyContin, and NCT01571362 was a Phase 3 study in chronic low back pain with 410 participants.

Is ALO-02 the same as OxyContin?

ALO-02 is not the same as OxyContin. ALO-02 contains oxycodone and naltrexone in an extended release formulation, while OxyContin contains only oxycodone. A Phase 1 study compared the pharmacokinetics of ALO-02 and OxyContin.

How does ALO-02 work?

ALO-02 contains oxycodone, an opioid agonist, and naltrexone, an opioid antagonist. The naltrexone is sequestered in the formulation to deter abuse. When taken as directed, oxycodone provides pain relief, while the naltrexone is intended to be released if the drug is crushed.
