Despite overall positive results,
Avalanche Biotechnologies
stock dropped
after questions were raised regarding the company’s Phase II trial design for wet age-related macular degeneration.
Avalanche Biotechnologies
, located in Menlo Park, Calif.,
announced
results yesterday of its Phase IIa study and a Phase I 36-month follow-up safety study for AVA-101.
Avalanche
indicated that the Phase IIa study met its 12-month primary endpoint, showing the drug was well tolerated and had a favorable safety profile. Patients also showed improved best corrected visual acuity (BCVA) compared to the control group, and demonstrated a positive trend in response rate.
That all seems quite promising.
“The results of this study confirm the Phase I safety results and suggest that AVA-101 could potentially benefit a significant portion of patients with wet AMD who require regular treatment with anti-VEGF therapy,” said
Samuel Barone
,
Avalanche
’s chief medical officer in a statement. “The current standard of care in wet AMD requires frequent anti-VEGF infections, which present a significant burden for patients and their caregivers, and can result in reduced treatment compliance and under-treatment. Therefore, a product that can maintain or improve vision while reducing the number of treatment injections would represent a powerful new option for patients and physicians.”
But something went wrong during the
conference call yesterday afternoon
when analysts began to examine more closely the study’s secondary efficacy endpoints. These were related to visual acuity, the number of rescue injections and measurements of retinal thickness. These, apparently, had significantly less clear results.
In addition,
analyst expressed concern
that the way the study was designed did not show a statistically significant difference between the control arm and the AVA-101 patients.
Also, there is some questions regarding a possible development deal between
Avalanche
and
Regeneron Pharmaceuticals, Inc.
for the rights to AVA-101 now. On May 5, 2014, Regeneron and
Avalanche announced
a collaboration to develop drugs for ophthalmologic diseases, particularly utilizing novel gene therapy vectors and proprietary molecules. As part of that deal,
Regeneron
has a time-limited right to first negotiation for AVA-101.
Avalanche
may provide more results at the
American Academy of Ophthalmology (AAO)
meeting in November about the drug and its possible deal with
Regeneron
.
Tim Lugo
, an analyst with
William Blair
, said on
Benzinga
, “We believe the performance of Lucentis in the control arm raises more questions than answers.”
William Blair
’s report went on to say, “While the next major catalyst for shares is a potential deal between both
Regeneron
and
Avalanche
, it is likely beneficial for both parties to wait until Phase IIb results to enter discussions as both parties (and the market) will likely have difficulty in valuing AVA-101 as an asset until additional results are available.”
Avalanche Biotechnologies
stock
was selling for $40.79 per share on June 11. It is currently selling for $18.75. It sold for a high of $60.08 on Jan. 7, 2015.
William Blair
downgraded the stock from
Outperform to Market Perform
.
Suntrust
also downgraded the study from
Buy
to
Neutral
.
Jefferies
maintained a
Buy
rating.
On the other hand, analysts
Joshua Schimmer
,
Steven Breazzano
and
Jerry Yang
of
Piper Jaffray
are more positive overall about the company, noting in a research report, “the data is largely in line with our expectations, showing what we believe is real biological activity in a subset of responders with meaningful reduction in injection frequency, along with improvements in BCVA, but also with plenty of room for improvement.”
They note that it’s still early and that the company’s overall “expanding gene therapy pipeline and vector evolution strategy… is underappreciated in our view.”
After AstraZeneca CMO Abruptly Quits, Where Could He Be Headed?
This week the chief medical officer of British drugmaker
AstraZeneca PLC
abruptly
quit his post
to become the chief executive officer of an unnamed, smaller biotech company. That’s lead
BioSpace
to wonder, with his background in R&D and in large companies like
Pfizer Inc.
, where will
Briggs Morrison
wind up? We want to know your thoughts.
