AUSTIN, Texas, May 11, 2015 (GLOBE NEWSWIRE) — Pain Therapeutics, Inc., (Nasdaq:PTIE) today announced an update regarding its portfolio of drug candidates. After staying quiet for the past six months, management expects an uptick in news flow for the rest of 2015. Expected milestones include a clear path to the FDA for re-filing the REMOXY NDA, announcement of proof-of-concept results for an abuse deterrent transdermal pain patch and announcement of non-dilutive funding for a new drug development initiative in a major indication.
“We’ve substantially completed the transition of REMOXY from our previous corporate partner,” said Remi Barbier, President and CEO of Pain Therapeutics. “We believe the data we’ve seen absolutely supports re-filing the REMOXY NDA. We expect to do so in Q1 2016.”
- We believe REMOXY’s previous sponsor undertook substantial studies and expenses to address the deficiencies previously noted in REMOXY’s 2011 Complete Response letter. We also believe the collective data generated from these new studies form the basis to re-file the REMOXY NDA.
- We believe the adequacy of the clinical data generated by REMOXY’s previous sponsor will not require us to conduct any new clinical studies to re-file the REMOXY NDA.
- We plan to conduct certain non-clinical activities prior to re-filing the REMOXY NDA. This includes in vitro work that was initiated but never completed by REMOXY’s previous sponsor due to the timing of their decision to return REMOXY. It may take us up to six months to conduct such work, depending on the workflow and availability of our consultants and vendors.
Results of Clinical and Non-Clinical Studies
- REMOXY’s previous sponsor conducted several studies prior to returning REMOXY to us. We believe results of these studies all support a resubmission of the REMOXY NDA, including:
- Comparative Bioequivalence Study
- Dose Proportionality Study
- Alcohol Interaction Study
- Effect of Food Study
- Human Abuse Potential Study
- REMOXY’s previous sponsor reached agreement with the FDA on the specific contents of an acceptable NDA resubmission. As with all regulatory documents, this agreement is now assigned to us as part of the REMOXY transition. We believe these regulatory documents create a clear path to the FDA for re-filing the REMOXY NDA.
- We plan to refile the REMOXY NDA with FDA in Q1 2016. If accepted by the FDA, we believe the REMOXY NDA will undergo a six-month review cycle.
- We have assembled a highly experienced team of experts, consultants and vendors from a range of disciplines to handle the complexities of preparing an electronic NDA submission.
Manufacturing and Supply Chain Strategy
- REMOXY’s previous sponsor contracted drug manufacturing to Mallinckrodt, a global company with distinctive manufacturing skills around opioids. The long-term drug supply agreement between REMOXY’s previous sponsor and Mallinckrodt is now assigned to us as part of the REMOXY transition. We intend to continue retention of Mallinckrodt for contract manufacturing and supply chain support for REMOXY.
Marketing and Commercialization Strategy
- We believe REMOXY targets a large market that requires significant expertise and marketing resources.
- We plan to select a commercialization strategy as REMOXY moves closer to a potential regulatory approval. We have identified several potential commercialization strategies that we have under review. These potential strategies include consummating a strategic transaction that monetizes our pipeline of drug candidates, forming a commercial collaboration or building a small, highly focused sales and marketing team.
- The following clinical manuscript was recently published in Journal of Opioid Management1:
The pharmacokinetics of oxycodone and its metabolites following single oral doses of REMOXY®, an abuse-deterrent formulation of extended-release oxycodone, in patients with hepatic or renal impairment.

- Over 10 years ago, we pioneered new abuse deterrent technology for oral opioid formulations. Today, we are pioneering new abuse deterrent technology for transdermal patch formulations. We believe the annual market for transdermal pain patches exceeds $1 billion in the U.S., and includes such opioid analgesic drugs as fentanyl, sufentanil, buprenorphine, etc. We believe the abuse deterrent technology that underlies FENROCK addresses a portion of these markets.
- We own world-wide commercial rights to our drug candidate FENROCK, which is a proprietary abuse-deterrent fentanyl pain patch. This drug candidate is in pre-IND stage of development.
- In Q3 2015, we expect to announce pre-clinical proof-of-concept data for FENROCK.
NEW DRUG INITIATIVE
- In Q2 2015, we expect to announce a major new drug development initiative for CNS diseases. Our undisclosed new drug candidate targets a large, non-pain, and underserved chronic market. We own all world-wide commercial rights to our new drug candidate.
- In Q2 2015, we also expect to announce a new, non-dilutive source of funding that is intended to substantially fund all IND-enabling activities for our undisclosed new drug candidate.

We own world-wide commercial rights to our lead drug candidate, REMOXY Extended-Release Capsules CII, which is a unique, twice-a-day formulation of oral oxycodone. REMOXY’s intended indication is for the management of moderate-to-severe pain when a continuous, around-the-clock opioid analgesic is needed for an extended period of time and for which alternative treatments are inadequate. We specifically developed REMOXY to discourage certain common methods of drug tampering and misuse. The REMOXY NDA is supported by multiple clinical trials, including a successful Phase III efficacy program conducted under a Special Protocol Assessment.
