Mallinckrodt confirmed receipt of a request for information from U.S. Sen. Claire McCaskill of Missouri, Ranking Democrat on the Senate Homeland Security and Governmental Affairs Committee. The Senator’s inquiry relates to OFIRMEV® (acetaminophen) injection, a patented, intravenous form of acetaminophen. OFIRMEV is an effective, non-opioid analgesic used to manage acute pain that, in addition to reducing pain, is proven to significantly reduce opioid consumption across various surgical settings.1,2,3,4,5
Retrospective studies suggest use of OFIRMEV may be associated with reduced costs to the hospital system and may help improve certain patient outcomes.6,7,8 One recent analysis of health economic data on the use of OFIRMEV coupled with a one-level reduction in opioid use was linked to decreasing hospital stays, potential opioid-related complications and related costs for the treatment of acute surgical pain. The study showed a potential of $4.7 million in annual savings for a typical, medium-sized hospital.9 Additional information on other analyses may be found at Mallinckrodt.com in the News section. The clinical benefit of reduced opioid consumption with OFIRMEV has not been evaluated nor demonstrated in prospective, randomized controlled trials.
Mallinckrodt has previously met with and provided information to the Senator’s staff on OFIRMEV. We will continue to work with Sen. McCaskill and her staff to assure the clinical and economic value of OFIRMEV is well understood.
OFIRMEV Ownership, Pricing and  Investment
  OFIRMEV  became part of Mallinckrodt’s portfolio in March 2014, through the acquisition  of Cadence Pharmaceuticals. At that time, OFIRMEV, the only product owned by  Cadence had, for several years, been losing tens of millions of dollars  annually, as reflected in Cadence’s public filings with the Securities and  Exchange Commission.10 In May 2014, Mallinckrodt  sought to stabilize OFIRMEV’s financial situation by increasing the drug’s list  price from $14.75 per vial to $35.40 per vial, not including significant  customer discount opportunities.   
  To put that  price into context, often the quantity used for a patient undergoing a surgical  procedure for which OFIRMEV is appropriate is fewer than four vials or  currently around $150 in cost, not including discounts. (A full case of OFIRMEV  includes 24 vials.) In contrast, public data indicates that the average payment  a hospital receives for these types of surgeries can rise to tens of thousands  of dollars per episode. 
Since owning the product, Mallinckrodt has made significant investments to support and demonstrate OFIRMEV’s value, including completing more than half a dozen retrospective health economic and outcomes research studies to provide additional insight for clinicians, pharmacists and hospital administrators on the value of OFIRMEV in acute pain management in the surgical setting. These studies reinforce Mallinckrodt’s commitment to providing hospital customers with high-value products that address the clinical needs of patients.
The company is also launching an innovative “Prove It Out” demonstration program that provides OFIRMEV at a significantly discounted price, enabling hospitals to utilize their own experience to demonstrate the benefits and value of the medicine, including potentially reducing hospital lengths of stay. Moreover, Mallinckrodt’s contracting strategy provides strong incentives to hospitals, where greater discounts are associated with increasing OFIRMEV use and reducing opioid use.
Since the necessary 2014 price reset, any price increases for OFIRMEV have been aligned with Mallinckrodt’s Pledge on Drug Pricing and Innovation, which governs our pricing decisions and can be found here: http://www.mallinckrodt.com/corporate-responsibility/drug-pricing-innovation.Mallinckrodt’s Role in the Fight  Against Opioid Abuse and Misuse
  The opioid  epidemic is a complex and confounding problem, and no one policy initiative or  program will solve it. Mallinckrodt has invested millions of dollars in its  comprehensive program to address opioid  abuse and misuse. For multiple years, Mallinckrodt has been a vocal advocate  for the prescription drug monitoring program in Missouri. The company purchased  and donated more than 1.5 million drug deactivation pouches distributed in our  communities in Missouri and across the U.S. so that families can actively  address concerns with the responsible use of pain medications and patient  safety.
We work with law enforcement to help prevent misuse and diversion, including by providing no-cost placebo tablets of Mallinckrodt opioids to officers and prosecutors for use in law enforcement operations; attacking drug theft through tracking devices in selected Mallinckrodt drug bottles; and contributing testimony on behalf of prosecution in drug diversion cases. We also helped to found the Anti-Diversion Industry Working Group, a collective of leading manufacturers and distributors of pharmaceutical controlled substances coming together to collaborate and share best practices with the purpose of exceeding U.S. Drug Enforcement Administration obligations for opioid anti-diversion programs.
To truly make an impact on opioid abuse, all stakeholders must better understand the various interrelated causes and contributors to the problem, and work together to address all of them in a comprehensive, thoughtful manner. We continue to work to be part of the solution.

  OFIRMEV is the first and  only IV formulation of acetaminophen to be approved and currently marketed  in the United States. The U.S. Food and Drug  Administration approved OFIRMEV in November 2010. OFIRMEV is  available to hospitals and outpatient and ambulatory surgical centers across  the U.S.
 INDICATIONS AND USAGE
OFIRMEV®(acetaminophen) injection is  indicated for the management of mild to moderate pain in adult and pediatric  patients 2 years and older, the management of moderate to severe pain with  adjunctive opioid analgesics in adult and pediatric patients 2 years and older,  and the reduction of fever in adult and pediatric patients.
IMPORTANT SAFETY INFORMATION
WARNING: RISK OF MEDICATION ERRORS AND    HEPATOTOXICITY 
 OFIRMEV contains acetaminophen. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed the recommended maximum daily limits, and often involve more than one acetaminophen-containing product.  |
