Teva stands by its MS pill after yet another setback
European regulators recommended against Teva Pharmaceutical's (
$TEVA)
laquinimod, marring the Israeli company's odds of crossing the finish line with its once-promising
multiple sclerosis treatment, a drug it hopes can dull the blow of the soon-to-go-generic Copaxone.
The European Medicines Agency's Committee for Medicinal Products for
Human Use took issue with the drug's risk-benefit profile, pointing to
safety risks that popped up in animal studies and weren't dispelled by
human trials. Long-term exposure to the drug was tied to a higher
occurrence of cancers and some dangers for pregnant women, CHMP said,
and regulators weren't convinced by Teva's proposed safety measures. On
the efficacy side, despite laquinimod's ability to slow the progression
of MS-related disability, regulators were unimpressed with the drug's
effect on relapses.
But Teva and partner
Active Biotech
aren't giving up, requesting a re-examination and planning to "liaise
closely with the EMA" in hopes of salvaging laquinimod's future in
Europe.
The rejection is the latest in a long line of woes for the oral drug,
which endured two Phase III blemishes after failing to significantly
reduce relapse rates in MS patients. In a third late-stage study,
laquinimod met its primary endpoint of delaying disease progression,
Teva said, but analysts remain skeptical on whether it can contend with
Biogen Idec's (
$BIIB) recently launched
Tecfidera.
Teva has remained optimistic about the drug through and through, and the company believes it can secure FDA approval by 2018.
Meanwhile, Copaxone, Teva's $4-billion-a-year MS mainstay, is on the
verge of generic competition, with patent protection set to expire next
year.
