Although the chronic pain market is largely saturated with reformulations of well-established molecules, developers continue to pursue products that have potential to fulfill the remaining unmet clinical need for analgesics that are well tolerated and can safely and effectively control pain over a long period of time. Historically, U.S. PCPs and pain specialists routinely prescribed strong opioid analgesics such as hydrocodone/acetaminophen (AbbVie’s Vicodin, generics) or controlled-release oxycodone (Purdue Pharma’s OxyContin) for the treatment of moderate to severe chronic noncancer pain. However, the use of opioids for the long-term management of chronic noncancer pain may decline as a result of increased public awareness of the prescription opioid abuse epidemic and the FDA’s introduction of the class-wide Risk Evaluation and Mitigation Strategy program in March 2013 for extended-release and long-acting opioid products. Unfortunately, the late-stage chronic pain pipeline is composed largely of reformulations of already-available molecules and features few agents that are truly novel. With the availability of multiple generic analgesic options, and with several key chronic pain therapies facing an end to their U.S. market exclusivity in the near term, factors driving treatment and reimbursement decisions in the United States are certain to change.
Key products in the chronic pain market include the following:
- Janssen Pharmaceuticals’ dual-acting opioid analgesic Nucynta ER (tapentadol ER), a mu-opioid receptor agonist and norepinephrine reuptake inhibitor that became available in 2011 for the management of moderate to severe chronic pain in adults when an around-the-clock opioid is needed for an extended period of time and was subsequently approved (in August 2012) for painful diabetic neuropathy, making it the first and only opioid approved for a neuropathic pain indication.
- AstraZeneca/Pozen's Vimovo (naproxen/esomeprazole), a fixed-dose combination tablet containing the NSAID naproxen and the proton pump inhibitor esomeprazole that became available in 2009. Vimovo is indicated for the relief of the signs and symptoms of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis and to decrease the risk of developing gastric ulcers in patients at risk of developing NSAID-associated gastric ulcers.
- Purdue’s BuTrans (buprenorphine transdermal patch), a seven-day transdermal patch delivering 5, 10, or 20 mcg/hr buprenorphine that became available in 2011 for the management of moderate to severe chronic pain in adults when a continuous, around-the-clock opioid is needed for an extended period of time.
In this report, we explore the use, reception, and formulary status of these key current and recently approved chronic pain therapies across multiple chronic pain populations in a survey of 70 primary care physicians (PCPs), 71 pain specialists, and 30 managed care organization directors. We also gauge payer and physician outlook toward four late-stage emerging therapies: Pfizer’s Remoxy, Pfizer’s tanezumab, Zogenix’s Zohydro, and BioDelivery Biosciences’ BEMA buprenorphine. By understanding the attitudes and expectations of prescribers and payers toward current, recently approved, and emerging chronic pain therapies, stakeholders can gain an understanding of the treatment paradigm and changing reimbursement climate for chronic pain.
