FDA’s Drug Approvals in 2015: Novel Drugs & New Versions of Existing Drugs

Each year, the US Food and Drug Administration (FDA) approve hundreds of new medications. A small subset of approvals, classified as novel drugsare 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.
