We usher in 2023 with the key highlights of the US Food and Drug Administration’s December 2022 list of Off-Patent, Off-Exclusivity (OPOE) Drugs with No Approved Generics. With this list, the FDA hopes to bolster competitiveness
in the generics market.The OPOE list gets updated every six months. Such updates are a part of FDA’s initiative to improve transparency and encourage the development and submission of abbreviated new drug applications (ANDAs) in markets with little competition.Since 2017, the FDA has been publishing the OPOE list of drugs without an approved generic. For a year now, the FDA has been publishing two versions of the OPOE list — one for prescription drug products and one for over-the-counter (OTC) drug products that are approved and marketed under a new drug approval (NDA).View FDA's 2022 List of Off-Patent and Off-Exclusivity Drugs (Free Excel)Four
new applications added to Dec 2022 list; 96 first generics approved last yearWhile the FDA’s June 2022 list of OPOE Drugs with No Approved Generics had 98 new applications for prescription drugs, the December 2022 list saw a sharp decline — only four new applications were added during this period. We had witnessed a similar trend in 2021 — the December 2021 list had only 16 new applications as
opposed to 35 new applications in the June 2021 list.The four new applications were for diclofenamide (a drug to treat glaucoma), ephedrine sulfate (a drug used to treat asthma and
heart failure that also acts as a central nervous system stimulant), meloxicam (an arthritis drug) and pemetrexed (a chemotherapy medication). In
May 2022, the FDA approved the first generics for pemetrexed injection
developed by several companies, including Accord Healthcare, Fresenius Kabi, Apotex, Qilu Pharmaceutical, Biocon, Dr. Reddy’s Laboratories and
Zydus, to treat non-small cell lung cancer (NSCLC) and mesothelioma. Almost one-third of the prescription products – 184 out of 505 – are drug products delivered as injectables, and 68 entries are for oral solid dosage forms (such as tablets, capsules and modified release forms).In the June 2022 list, a total of 60 OTC
drug products were listed. This time too, the same number of OTC drug products
figured in the OPOE list. These include antiseptic agent chlorhexidine gluconate,
non-steroidal anti-inflammatory drug ibuprofen, anti-allergy drug loratadine and painkiller acetaminophen. Of these, 19 are delivered as
oral solid dosage forms (such as
tablets, capsules and modified release forms).In 2022, the FDA approved 96 first generics. This is slightly higher than
the 93 approved by the agency in 2021.As the name suggests, “first generics” are the first approvals handed by the FDA to manufacturers to market a generic product in the United States. The agency considers first generics to be important to public health, and prioritizes review of these submissions.View FDA's 2022 List of Off-Patent and Off-Exclusivity Drugs (Free Excel)AbbVie’s Humira, Novartis’ Entresto to finally face generic competitionAbbVie is facing one of the steepest patent cliffs in the industry’s history, with Humira slated to face the onslaught
of eight biosimilars this year. The blockbuster drug had generated US$ 21.2 billion in 2021. Amgen’s Humira biosimilar – Amjevita – will hit the market this month. The other Humira
biosimilars that will be launched this year include Abrilada (Pfizer), Cyltezo (Boehringer), Hadlima (Samsung Bioepis), Hyrimoz (Sandoz), Hulio (Viatris) and Yusimry (Coherus BioSciences). In mid-December, Fresenius Kabi became the latest
company to win US approval for its Humira copycat — Idacio.Novartis’ heart failure drug Entresto will also go off patent this month. The blockbuster drug had generated US$ 3.5 billion in 2021.View FDA's 2022 List of Off-Patent and Off-Exclusivity Drugs (Free Excel)Our viewIn our previous OPOE drug listing, we had talked about FDA’s intent to bring down drug prices, with the agency putting 98 new applications of prescription drugs in the OPOE list for June 2022. That intent has only become stronger with the US Patent and Trademark Office (USPTO) and the FDA joining hands to promote
competition. The two bodies are working towards improving the patent system in an effort to stop its misuse through “patent thickets”, “evergreening” and “product-hopping”. With this clear intent to lower drug prices in the US, the OPOE lists for 2023 and beyond are likely to get more interesting. For now, all eyes are set on what generic competition will do to blockbusters like AbbVie’s Humira and Novartis’ Entresto.

Each year,
the US Food and Drug Administration (FDA) approve hundreds
of new medications. A small subset of approvals, classified as novel drugs, are considered to
be truly innovative products that often help advance clinical care.
In 2015, the
FDA approved 45 novel drugs, an all-time record high. PharmaCompass has compiled a list of novel drugs approved by the FDA in 2015.The FDA also approved new dosage forms of existing products in the market (email us if you would like a copy), like the 3D printed version of anti-epilepsy drug, Spritam (Levetiracetam).
This week, PharmaCompass focuses on the new dosage
forms of existing drugs that got approved last year.
Modified blockbusters
Improving the delivery form of a blockbuster drug is something that not only helps patients but often successfully extends the patent life of the cash-generating drugs for Big Pharma. Here are some blockbuster drugs that saw their modified versions being launched in 2015:
Jadenu (deferasirox): With
almost a billion dollars in revenues in 2015, Exjade (deferasirox) was approved in 2005 as a
tablet for use in a suspension. Novartis, the innovator,
got approval in March 2015
for Jadenu, a once-daily oral tablet. Jadenu (deferasirox), a new formulation
of Exjade, is the only once-daily oral tablet for iron chelation. Jadenu has
simplified daily treatment administration for patients with chronic iron
overload.
Nexium
24HR (esomeprazole magnesium): Also
known as the Purple Pill, Nexium – Astra
Zeneca’s blockbuster drug for acid reflux that generated annual sales in America of more than US $ 3 billion – went generic in 2015. In order to extend Nexium’s market, Pfizer and AstraZeneca came together to promote an over-the-counter (OTC) version of Nexium. A capsule version of OTC Nexium was approved in 2014 and is known as
Nexium 24HR. Last year, the FDA granted approval to the tablet form of the
drug.
Iressa
(gefitinib): AstraZeneca re-introduced Iressa in
the US market in 2015. The
FDA had approved Gefitinib in May 2003 for non-small cell lung cancer. Approved
as a third-line therapy, in 2010 the FDA requested AstraZeneca to voluntarily withdraw Iressa tablets
from the market, as post-marketing studies had failed
to verify and confirm clinical benefit. Iressa (gefitinib) is now back in the US as a first-line therapy for a type of lung cancer. However, the patent protection is limited – only one listed patent in the Orange Book which expires next year, and five US Drug Master Files already submitted.
Onivyde (irinotecan): Liposomal formulation of anti-cancer
drugs have been in vogue for some time. Merrimack Pharmaceuticals got its novel encapsulation of Irinotecan in a liposomal formulation approved for the
treatment of patients with metastatic pancreatic cancer, sold under the brand
name Onivyde.
Vivlodex (meloxicam): In October 2015, the FDA approved 5 mg and 10 mg (administered once daily) doses of Vivlodex™ (meloxicam) capsules, a nonsteroidal anti-inflammatory drug (NSAID) used for the management of osteoarthritis pain. The previously approved doses for meloxicam capsules were 7.5mg and 15mg. Vivlodex uses a proprietary SoluMatrix Fine Particle Technology™, which contains meloxicam as submicron particles that are approximately 10 times smaller than their original size. The reduction in particle size provides an increased surface area, leading to faster dissolution.
Kalydeco (ivacaftor): A cystic fibrosis drug from Vertex Pharmaceuticals – Kalydeco – has been making headlines
because of its high price (more than US $ 300,000 a year). Price concerns
aside, 2015 saw the launch of a pediatric version of the drug as a ‘weight-based oral granule formulation of Kalydeco that can be mixed in soft foods or liquids’.
Extended release versions
Many of
the approvals granted by the FDA last year were to extended release
formulations (a pill formulated so that the drug is released slowly) of
existing drugs.
Kremers Urban’s
extended release version of Methylphenidate
capsules made headlines last year because of a reclassification of the drug by
the FDA. Under the new classification rating, methylphenidate hydrochloride extended-release tablets can be prescribed but may
not be automatically substituted for J&J’s reference drug Concerta (methylphenidate hydrochloride). Kremers Urban was almost sold last year. But due to this reclassification, investors aborted their US $ 1.53 billion buyout. Kremers Urban was later acquired by Lannett Company Inc.
In
addition, extended-release versions of Aspirin, Carbidopa/Levodopa, Paliperidone Palmitate, Tacrolimus
and Morphine Sulphate also received green signals for a market launch.
First generic opportunities
Last year, PharmaCompass
shared the names of some drugs which had no generic competition and were also
not protected by patents. (Read: “Litigation Free, first generic opportunities list”).
Deferiprone (a drug that chelates iron and is
used to treat iron overload in thalassemia major) met the criteria. But it still
has no generic competitor and is now available as a new dosage form.
Amedra Pharmaceuticals, now owned by Impax Laboratories, has enjoyed the rights to sell Albendazole tablets for almost two decades
without generic competition in the US. Albendazole is a medication used for the
treatment of a variety of parasitic worm infestations. In 2015, patients were
provided access to chewable tablets of Albendazole.
New combinations at work
The FDA also approved
multiple combination drugs where the individual active ingredients had been brought
to market previously.
Most of the combination drugs
approved belong to major pharma players like Novartis, Novo Nordisk, Bristol Myers etc.
Boehringer’s diabetes treatments – Jardiance (empagliflozin) – approved in 2014 and
Tradjenta (linagliptin) approved in 2011, were
combined and the combination drug product Glyxambi was approved in 2015. Another
combination of empagliflozin, with metformin – Synjardy – was also approved in August last
year.
Lesser known companies also
got combination drugs approved. UK-based
development company Vernalis got approval for its cold-cough treatment, Tuzistra XR – an extended release suspension of codeine polistirex and chlorpheniramine
polistirex.
Similarly, US-based biopharmaceutical startup, Spriaso LLC, also
working in the cold and cough therapeutic area, got an extended release tablet
containing codeine phosphate and chlorpheniramine maleate approved.
Symplmed, a company which is
developing various forms of Perindopril, got approval for Prestalia (a
combination of perindopril arginine and amlodipine besylate) for the
treatment of hypertension.
Our view
Each year, the FDA approves several
pharmaceutical drugs in order to improve patient care; and often versions of
these drugs are marketed and distributed across the globe.
