Now that it has been
established that the novel coronavirus is going to globally impact the drug
supply chain, it becomes imperative to analyze the extent of the impact.
Since the outbreak of
the novel coronavirus — COVID-19 — in December, PharmaCompass has been constantly reaching out to
manufacturers around the world to assess the current state of the drug supply
chain. This week, we share our preliminary analysis based on the feedback we
have received from drug manufacturers around the world.
Drug shortages are
for real
Last week, the US
Food and Drug Administration (FDA) announced the first human drug shortage
as a result of the coronavirus outbreak. In addition, the FDA announced it was
tracking 20 drugs that could face shortages. Some generic drugmakers are predicting shortages
as early as in June or July, due to the novel coronavirus.
The FDA did not disclose the name of the drug in shortage or the 20 drugs it is tracking, as this is considered ‘confidential commercial information’.
In India, a committee constituted by the country’s Department of Pharmaceuticals started monitoring the availability of 58 active pharmaceutical ingredients (APIs) to take preventive measures
against illegal hoarding and black-marketing in the country.
According to a report published in The Economic Times, after
reviewing the list of drugs, 34 were found to have no alternatives which
include critical and essential drugs like potassium clavulanate, ceftriaxone sodium sterile, piperacillin tazobactam, meropenem, vancomycin, gentamycin and ciprofloxacin.
This was immediately
followed by the Indian government restricting the exports of 13
APIs along with some of their finished formulations. The list includes paracetamol, tinidazole, metronidazole, acyclovir, vitamin B1, vitamin B6, vitamin B12, progesterone, chloramphenicol and neomycin. For most
of the products on this list, India is a net importer, as there is little
domestic manufacturing of these APIs.
COVID-19 is also
likely to impact bottomlines. Leading generic drugmaker Mylan said it expects the coronavirus outbreak to impact its financial results
while some of the largest drugmakers — including AstraZeneca, Merck and Pfizer — have said that the coronavirus outbreak could affect their supplies or sales.
Paracetamol
affected; prices double in less regulated markets
The decline in industrial activity in China is certainly taking its toll, as drugs which are on the World Health Organization’s Model list of Essential Medicines are beginning to face significant price increases in the wake of disruption of key starting raw materials for bulk drugs.
The export
restriction out of India on commonly used analgesic, Paracetamol — sold under the brand names such as Tylenol (in the US), Panadol (in the UK), Dafalgan (France) and Crocin
(India) — is not surprising as the API has witnessed almost doubling of prices in less regulated markets because exports of its key building block para-amino phenol (PAP) have dramatically reduced from China.
While there are only
a few manufacturers who produce paracetamol without being dependent on Chinese
PAP, a few major manufacturers in India depend almost completely on Chinese PAP
for their paracetamol production and usually only keep three to four months of
inventory.
By the end of
February, their inventory stockpiles had halved and in the event of a continued
supply disruption, their entire inventory pipeline is likely to dry out. In
addition, Chinese paracetamol manufacturers, who export a significant amount of
their bulk ingredient production globally, including to India, are also
currently unable to export. This is beginning to create the potential of panic
among sourcing executives across the world.
Several
antibiotics also in danger of acute shortages
While paracetamol was listed on the API watch list circulated by India’s Department of Pharmaceuticals, our survey has revealed that other products on the list like ciprofloxacin, amoxicillin and azithromycin are also facing severe raw material
shortages. As a result, the prices of these bulk drugs have also increased
sharply.
In a statement to The Economic Times, leading Indian generic manufacturer Mankind Pharma’s chairman and managing director said
amoxicillin is the most commonly used API to manufacture antibiotics and the
company has invested Rs 1 billion (US$ 14 million) in placing irregular orders
with vendors to try and address the potential shortage that is expected. He
went on to say that if the situation continues until April, there will be an
acute shortage.
In a statement to the US House of Representatives last October, Janet Woodcock, the FDA’s Director of Center of Drug Evaluation and Research, said the FDA has determined that there are three WHO Essential Medicines whose API manufacturers are based only in China. The three medicines are: capreomycin, streptomycin (both indicated to treat Mycobacterium
tuberculosis) and sulfadiazine (used to treat chancroid and trachoma).
Streptomycin is also on the watch list published by India’s Department of Pharmaceuticals along with commonly used anti-hypertensives like losartan, valsartan, telmisartan and olmesartan and diabetes treatment metformin.
Intermediates
becoming a problem for generic drugmakers
PharmaCompass’ discussions have also revealed that in many cases while API manufacturing factories in China have returned to work, there are disruptions in the availability of raw materials and/or logistics at sea ports and airports which have led to unavailability of supplies.
While the FDA has a
list of the number of API facilities in China which are in a position to supply
to the United States, Woodcock said in her statement that the FDA “cannot determine with any precision the volume of API that China is actually producing, or the volume of APIs manufactured in China that is entering the US market.”
This visibility
reduces drastically when one has to assess the dependence of each API
manufacturer around the world on China for intermediates. Our discussions have
revealed that it is these intermediates which are becoming a problem for most
API manufacturers, even those based in India.
It was worth
highlighting that a manufacturing process change at an intermediate stage of
commonly used blood pressure medicine valsartan resulted in the recall of
millions of pills as it was found to contain a cancer causing impurity above
acceptable levels. Similarly, in 2008, the adulteration of heparin in China,
which killed 81 people and left 785 severely injured, was an outcome of the
subcontracting of precursor chemicals of Heparin.
Our view
The over-dependence
on China for key starting materials has been the subject of discussion ever
since we launched PharmaCompass. Rosemary Gibson explored this subject
in detail in her book China Rx: Exposing the Risks of America’s Dependence on
China for Medicine.
The restrictions imposed on industrial activity and transportation in China in the first two months of this year has resulted in NASA’s satellite images showing a decline in pollution levels over China.
While China works
towards getting its industrial and transportation engine up and running to 2019
levels, the outbreak has spread to other countries which will further increase
the demand for drugs to fight the virus.
This is a time when
the pharmaceutical industry needs to act responsibly and make decisions which
are in the best interests of patients globally.
Sharing information is one such step — it will allow for drug stockpiles and inventories that exist to be re-distributed to areas which need them most. For, in the event of an urgent need, drugs will become available to those who are most in need.
