MNK main drugs:
Achtar gel (acquired in 2014 for $5.9bn): Injectable drug approved by the US Food & Drug Administration (FDA) not
protect by a patent. The drug is used as a last resort treatment for rheumatoid arthritis (RA), including juvenile RA and
monotherapy. Achtar gel has been criticized for massive price increases; in 2001, a vial cost $50 but it skyrocketed to
$40,000 by 2014.
The Achtar outlook is challenging with trends already being impacted by reimbursement pressures, price and duration in
treatment. Based on market intelligence, Achtar is difficult to replicate on a generic basis and potential competition
(ANIPharma, ~$400m market cap) appears to be a low threat of disruption. Achtar is a very niche drug and is necessary
for complex medical needs. MNK has been investing in clinical studies to grow alternative treatments, including a new
self injector with subscription pricing.
INOMax (acquired in 2015 for $2.3bn): is a gas for inhalation and a vasodilator that improves oxygenation, mostly
focusing on infants. The treatment has certain patents, but Praxair has successfully challenged them in court and is
expected to result in a competitor.
INOMax is a “closed loop” system with a razor / razorblade model and defensive moat. Praxair may bring a competitor in
the near future. Lower birth rates may weigh on future results, but Covid (ventilators) may yield higher volumes.
Therakos (acquired in 2015 for $1.3bn): is an integrated system for lymphoma patients which has a unique process of
separating red and white blood cells and returning reactivated white blood cells. Therakos is one of MNK’s more stable
products although Covid could dampen results due to fewer procedures.
Ofimev (acquired in 2014 for $1.3bn): IV injection of a proprietary acetaminophen formula to manage mild to moderate
pain. This drug faces patent expiration in 2021 and based on analysis of other “patent cliff” drugs, prices may fall by 30-
50% along with ~25% volume declines.
Amitiza (acquired in 2018 for $1.2bn): a leading product in the branded constipation market. Amitza was approved by
the FDA to treat chronic idiopathic. MNK faces generic competition from Endo due to its acquisition of Par
Pharmaceuticals. Amitza faces a challenging outlook due to a generic introduction in 2021 (US only) and soft results from
Covid. While US generic competition may soften results, Amitza posts strong & significant results in Japan.
Terlipressin (pipeline): an MNK pipeline drug (FDA approved in Sep-20, but more data is needed for an NDA) for treating
type 1 hepatorenal syndrome (HRS), an acute, rare and potentially life-threatening condition with no currently approved
therapy in the US. Peak sales are expected ~$300m. Even if the FDA does not approve Terlipressin, MNK could still
monetize its via M&A.
StrataGraft (acquired in 2016 for $116m): regenerative skin tissue for treatment of severe, deep partial thickness burns
– FDA accepted for review in Aug-20. In 2012, the FDA granted StrataGraft orphan product status, conferring seven
years exclusivity. Peak sales expected ~$150m, but it would require training surgeons so could take some time.
Specialty Generics: include a variety of product formulations containing hydrocodone-containing tablets, oxycodone-
containing tablets and several other controlled substances, all of which are significant pain treatment products. This
segment saw material annual declines (-14-18%) from 2015-2018 before stabilizing in 2019. Looking ahead, specialty
generic revenues should decline by ~5-9% per year.
Litigation notes:
Opioid makers and distributors: face over 2,000 lawsuits by states, counties and individuals. Drug manufacturers are
accused of misrepresenting opioid risks and benefits. Distributors (Amerisource Bergen, Cardinal Health and McKesson)
are accused of supplying opioids diverted to illicit markets.
A potential deal by opioid manufacturers Teva, Purdue, J&J, Endo and Mallinckrodt and competitors may cost ~$20-30bn
while several states have discussed $50bn.
