(Adds further details from MHRA spokesman)
By Zeba Siddiqui
MUMBAI, July 1 (Reuters) - The UK's healthcare regulator has
decided to suspended marketing approval for a widely used
antibiotic that had won clearance based on clinical trials
conducted by India's Quest Life Sciences, due to concerns over
the integrity of trial data.
The Medicines and Healthcare products Regulatory Agency
(MHRA) might also deny other pending drug approval requests that
rely on studies conducted by Quest, the UK agency said in a
letter dated June 22, a copy of which was seen by Reuters.
The MHRA's decision bars the sale of a generic version of
erythromycin that is being sold in the UK by Dawa Ltd, a Kenyan
drugmaker, an MHRA spokesman said.
The MHRA said it is in contact with the involved parties,
who have the right to appeal and submit new data to prove that
the drugs in question meet the required standards.
The agency added that it does not not believe there to be
any risk to public health and that its decision to suspend
marketing approval is purely a precautionary measure.
Quest's President Yati Chugh told Reuters the company plans
to appeal the suspension as he believes the agency relied on a
two-year-old study and the following inspection report to reach
its decision, and that it did not review the company's latest
quality management systems.
He said Quest had significantly improved its quality systems
since 2014, and would ask the MHRA to re-inspect its site, as
MHRA's move means four other drugs Quest performed trials on
that are awaiting approval with the UK regulator will not be
approved until the agency clears its facility.
These drugs include the antibiotics doxycycline and
cephalexin, and the diabetes drug metformin, on which Quest had
conducted trials on behalf of UK drugmaker Strandhaven and
India's Kopran, said Chugh.
Strandhaven, Kopran and Dawa did not respond to requests for
comment on the matter.
LATEST SETBACK
The MHRA's move is the latest blow to India's drug industry,
whose reputation has been tainted in recent years as foreign
regulators have criticised manufacturing standards and
questioned the reliability of clinical data produced by some of
the sector's biggest names.
Chennai-based Quest is a contract research firm that
conducts clinical trials on generic drugs on behalf of local, as
well as multinational drugmakers. Drugmakers in turn use
clinical data produced by companies like Quest to seek approval
to sell their drugs in various countries.
Data from Quest has been used to support drug approvals in
the United States, Europe, Australia and elsewhere, according to
its website.
The MHRA said that during an inspection of Quest's facility
in February, it found several issues with data integrity in a
clinical trial Quest had conducted, including discrepancies in
Quest's patient records and instances where electrocardiogram
(ECG) data of patients had been deleted or manipulated.
The World Health Organisation told Quest in July last year
about similar ECG data manipulation issues in another drug
study.
The MHRA said it believed its findings meant that the safety
or wellbeing of patients had been jeopardised in the trial.
"The MHRA inspectors identified a large number of issues
which indicated that there were very serious concerns with many
aspects of the company's quality system," the MHRA spokesman
said, adding the problems cast "serious doubt on the integrity
of any data produced."
Similar issues around data at Quest's larger rival GVK
Biosciences led to a recall of about 700 drugs across Europe
last year. (http://reut.rs/29dOFbW)
