At PharmaCompass, we highlighted
the significance of India in the global active pharmaceutical ingredient (API)
supply chain last week with our list of generic drug facilities registered with
the US Food and Drug Administration (FDA).
Our compilation revealed that India had
182 generic drug facilities registered with the FDA and this number was nearly
as much as the corresponding numbers for China (100) and United States (84) put
together. These 182 facilities paid a fee of US$ 59,400 each to the FDA.

This week, we review the API Drug Master
Files (DMFs) submitted to the FDA in 2019. Expectedly, India also led the DMF submission list.
In 2019, there were 616 active DMF submissions
to the FDA with Indian companies submitting more than half (331) of them.
Submissions from India were a little less than double the number of DMF
submissions made by Chinese (113) and the US (57) firms put together.
Drug master files (DMFs)
are submissions made to the FDA by manufacturers by providing the agency with
confidential, detailed information about facilities, processes, or articles
used in manufacturing, processing,
packaging, and storing of human drug products.

MSN Labs
leads total count of DMF filings
The 616 active DMF filings to the FDA were quite diverse — they covered over 400 products, and over half (322) the filings were for unique products.
Among the products with multiple DMF
filings, Sugammadex Sodium topped the list as it had 18 DMF
filings. Sugammadex is the API used in Merck’s Bridion for the
reversal of neuromuscular blockade induced by rocuronium and vecuronium in
general anesthesia.
The other products with over five DMF
filings were for the APIs of Lundbeck and Otsuka’s antipsychotic drug Brexpiprazole, Novartis, Gilead and Intercept’s blockbuster products Sacubitril-Valsartan, Tenofovir Alafenamide Fumarate and Obeticholic Acid.

The year 2019 also witnessed continued
DMF filings for Rivaroxaban, Sitagliptin Phosphate, Ticagrelor and Tipiracil Hydrochloride. These filings indicate that the
companies currently developing these products should brace themselves for
intense competition in the near future.
India’s MSN Labs continued to lead the count of total DMF
filings with 42, of which it had 17 filings where it was the only one
submitting a DMF for a specific product in 2019. The leading Chinese company
filing DMFs was Fuxin Long Rui Pharmaceutical with nine DMFs, followed by Brightgene Bio-Medical Technology Co with five.
The API DMF is part of
the final generic drug product submission to the FDA. Therefore, the owner of a
DMF incurs a one-time fee (US$ 55,013 for FY2019, US$ 57, 795 for FY2020) the
first time the generic drug submission references that DMF.

DMF holders may also pay
the fee in advance in order to have their DMF subjected to an initial
completeness assessment by the FDA. This would allow their DMF to be included
on a publicly-available list of DMFs that have paid their fee and not
failed the initial completeness assessment.
Aurobindo, Sun, Lupin lead DMF assessments
While reviewing the DMF submissions made in 2019, we found that a third (209 out of 621) of the DMFs were listed on FDA’s publicly-available list of DMFs that have paid their fee and whose initial assessment had been completed. This indicates that either companies may have been unwilling to pay the fee or the FDA’s review process found shortcomings in their applications.
Major Indian generic drug companies like Aurobindo (16), Sun Pharmaceuticals (13), MSN Labs (12), Lupin (7) and Macleods (7) led the list of companies that had
the maximum DMF assessments completed for their 2019 submissions.
There are also DMF submissions for
products which can sometimes indicate future drug approvals.

Sanyo Chemicals submitted a DMF for Ibudilast, an anti-inflammatory drug whose oral
capsules are used in Japan for the treatment of asthma and its ophthalmic
solution is used to treat allergic conjunctivitis. The product is currently not
approved in the United States.
New drug approvals in the future can also
be expected for Tertomotide, Omarigliptin, Estetrol Monohydrate, Abametapir, Pirenzepine, Cortexolone Proprionate, Lurbinectedin, Terlipressin, Ethyl Olivetolate, Remimazolam and Triapine. These products are currently under
clinical trials for a variety of indications.
Our view
After compiling the list of companies that have submitted DMFs to the FDA as well as the generic facilities that paid their user fees, it’s clear that the API industry is beginning to find a new equilibrium.

Our compilations of the previous years
have shown that there is a steady decline in facility registrations and DMF
filings. Given the increasing costs involved, as well as scaled up regulatory
requirements, it seems that companies are becoming more selective in their
product development decisions and also their willingness to do business in the
United States.
While the number of Indian API facilities
registered with the FDA has remained relatively unchanged, the number of
Chinese sites that registered with the US has reduced by 35 percent over the
past five years.
Several factors are changing the landscape of the generic drug industry. For instance, environmental regulations in China are driving up the cost of raw materials. Quality issues — such as the valsartan impurities case — have increased regulatory scrutiny. Moreover, passing inspections continues to remain a challenge for many manufacturers. And generic drug product manufacturers are also facing margin pressures, which in turn is driving a lot of M&A activity. Given this scenario, the generic industry should brace itself for more challenges in 2020.
