This week in Phispers, we bring you news on J&J’s Invokana, a drug that reduces heart risk while increasing the risk of amputation of toes. There is news from Google, which is tying up with India’s Aravind Eye Care System for its artificial intelligence eye doctor initiative. And WHO takes a step towards reducing antibiotic resistance by grouping antibiotics into ‘Access’, ‘Watch’ and ‘Reserve’.
Manufacturing errors trigger drug recalls by Lupin and Dr. Reddy’s in the US
Earlier this month,
we carried an article on the end of India’s pharma honeymoon.
News this week from Lupin and Cipla added another dimension to the problem as manufacturing
errors triggered drug recalls in the United States.
Lupin voluntarily recalled a lot of its birth control pills — Mibelas 24 Fe — in the US. A market complaint indicated a packaging error, making the lot number and expiration
date no longer visible. This product is an oral contraceptive for women.
As a result of the
packaging error, the FDA says the first four days of the birth control packet have four
non-hormonal placebo tablets as opposed to the active tablets. This may place
the user at risk for contraceptive failure and unintended pregnancy.
Similarly, Dr. Reddy’s had to recall hundreds of thousands of cartons of a popular acne medicine — Zenatane — manufactured by Cipla’s plant in Pune.
According to FDA enforcement reports, Dr. Reddy’s is recalling 190 lots, consisting of 778,279 cartons of its Zenatane brand isotretinoin capsules, in four dose sizes. The voluntary Class II recall was initiated in late May after the products failed dissolution testing.
During this period of
turmoil, the Indian company which is generating a lot of positive press is Cadila Healthcare.
Cadila’s US
division Zydus Pharmaceuticals’ subsidiary Nesher Pharmaceuticals has received final FDA approval to
market Nystatin Topical Powder, an anti-fungal
antibiotic used to treat skin infections caused by yeast.
There is more good
news from Zydus Cadila. After years of patent battles, the FDA has approved Zydus Cadila’s generic version
of Shire’s ulcerative colitis drug Lialda.
This came as a rude
shock to Shire investors who had believed the US$ 800 million drug was safe for
a few more years. However, there is a chance that instead of a flood of
generics, the Zydus' generic may be the only competition for Lialda for sometime.
Zydus Cadilla has indicated that its version will have a six-month exclusivity.
J&J’s diabetes
drug saves heart at the cost of toes; Sanofi’s insulin slashes hypoglycemia risks for seniors
Would you like to
sacrifice your toes to save yourself from a heart attack? Well, a diabetes drug
made by Johnson & Johnson (J&J), does just that. The drug — Invokana — decreases the risk of heart attacks and strokes, while increasing the risk of amputation,
particularly of toes.
According to the
results of the 10,142-patient study, funded by J&J, for every three heart
attacks, strokes, or cardiovascular deaths prevented by Invokana, there were
two amputations, 71 percent of them of toes or the lower foot.
While this is a setback to J&J, its rivals — Eli Lilly and Boehringer Ingelheim — who make a similar drug called Jardiance, may be cheering the findings of this
study, performed on sodium-glucose co-transporter 2 (SGLT2) inhibitors. These
drugs prevent the kidney from absorbing sugar from the blood.
But scientists are not sure why the drugs would prevent cardiovascular disease, and it’s unclear why one of them would lead to amputations. “It justifies the need to test each medicine,” Harlan Krumholz of Yale University said.
Another study
examining an at-risk population of seniors who
had switched to basal insulin found Sanofi’s Toujeo to outdo its peers at cutting the risk of
hypoglycemia in older patients.
During a six-month follow-up, the study found that amongst the ‘at-risk’ seniors, those taking Toujeo were 57 percent less likely to experience hypoglycemia than those who switched to competing insulins—such as Novo Nordisk’s Tresiba and Levemir, and Toujeo’s predecessor, Lantus.
Google ties up
with Indian hospital chain for artificial intelligence eye doctor initiative
Google will soon begin
work on a grand experiment that would use machines to widen access of
healthcare. If successful, this initiative will protect millions of diabetes patients
from an eye disease that leads to blindness.
Last year, researchers at Google had said they had trained image recognition algorithms to detect signs of diabetic retinopathy roughly as accurately as human experts. Left untreated, diabetic retinopathy causes blindness. The software examines photos of a patient’s retina to spot tiny aneurisms that would help detect early stages of the disease.
Google is working
with the Aravind Eye Care System in India, a network of eye hospitals, in order
to integrate this technology.
“This kind of blindness is completely preventable, but because people can’t get screened, half suffer vision loss before they’re detected,” Lily Peng, a product manager with the Google Brain AI research group, said. “One of the promises of this technology is being able to make healthcare more accessible.” There are more than 400 million people worldwide with diabetes, including 70 million in India.
FDA tells Endo to
pull out its opioid pain medication, as Gottlieb attacks addiction
Last week, the US FDA
asked drugmaker Endo Pharmaceuticals to remove its powerful opioid pain medication — Opana ER — from the market, due to “the public health consequences of abuse”.
“We are facing an opioid epidemic — a public health crisis — and we must take all necessary steps to reduce the scope of opioid misuse and abuse,” FDA Commissioner Dr. Scott Gottlieb said. “We will continue to take regulatory steps when we see situations where an opioid product’s risks outweigh its benefits, not only for its intended patient population but also in regard to its potential for misuse and abuse,” he added.
Opioid overdoses killed 33,000
Americans in 2015, with half of those involving a prescription opioid.
Opana ER, which is oxymorphone hydrochloride, is used to manage severe pain. The FDA
approved it for this use in 2006. The drug is about twice as powerful as OxyContin, another often abused opioid.
In 2012, Endo
reformulated the drug to make it more resistant to physical and chemical
tampering. While the drug met the standards for approval, FDA says Endo never
showed that the reformulation would reduce abuse.
Amgen loses bid to delay Novartis’ biosimilar; FDA rejects Coherus’ biosimilar for Neulasta
Amgen lost a case in the Supreme Court of the United States that
sought to delay biosimilars of its rivals. Amgen had argued that its biosimilar rivals
should be forced to delay their 180-day marketing notices until the FDA had
made up its mind on the marketing application.
However, on Monday, the Supreme Court took a decision by determining that the law never imposed a two-tier timing system for these notices. Therefore “the applicant may provide notice either before or after receiving FDA approval.”
This has proven to be
a clear win for Sandoz — the generic unit of Novartis that is fielding an array of copycat biologics. The group is launching a copy of Amgen’s Neupogen. And in the process, Sandoz has
unleashed a fresh wave of biosimilars hitting the US market.
However, Amgen won somewhere else — the FDA rejected Coherus Biosciences’ application for a biosimilar of Amgen’s blockbuster Neulasta (a drug that fights infections in cancer
patients). This action effectively delays any rival until 2018, at the
earliest.
The FDA's response
comes as Amgen gears up for biosimilar competition for Neulasta, which
generated about US$ 4.6 billion in sales last year. The FDA requested Coherus
for a re-analysis of certain data and asked the drug developer for more
manufacturing information.
WHO updates list
of essential medicines; groups antibiotics into three categories
Last week, the World
Health Organization (WHO) released its Essential Medicines List (EML), with a
new advice on which antibiotics to use for common infections and which to
preserve for serious circumstances. Amongst the additions to the WHO Model list of essential medicines
for 2017 are medicines for HIV, hepatitis C, tuberculosis and leukaemia.
The EML is used by
many countries to increase access to medicines. The updated list has added 30
drugs for adults and 25 for children, and specifies new uses for 9
already-listed products. In all, it contains 433 drugs deemed essential to
address the most important public health needs.
This time, WHO has grouped antibiotics into three categories – ACCESS, WATCH and RESERVE – with recommendations on when each category should be used.
Initially, the new
categories apply only to antibiotics used to treat 21 of the most common
general infections. If found useful, it could be broadened in future versions
of the EML to apply to drugs to treat other infections.
Antibiotics in the
ACCESS group must be available at all times as treatments for a wide range of
common infections. It includes drugs like amoxicillin, an antibiotic used to treat infections such as
pneumonia.
The WATCH group
includes antibiotics that are recommended as first- or second-choice treatments
for a small number of infections. For example, the use of ciprofloxacin, used to treat cystitis (a type of
urinary tract infection) and upper respiratory tract infections (such as
bacterial sinusitis and bacterial bronchitis), should be dramatically reduced
to avoid further development of resistance.
The third group, RESERVE, includes antibiotics that should be considered as last resorts, such as colistin and some cephalosporins. These must be used
only in the most severe circumstances when all other alternatives have failed.
