Amgen
, headquartered in Thousand Oaks, Calif.,
announced
today a collaboration with
Roche
on a Phase Ib clinical trial to evaluate talimogene laherparepvec combined with atezolizumab, also known as MPDL3280A for the treatment of triple-negative breast cancer and colorectal cancer with liver metastases.
Amgen
did not respond to a request for comment by deadline.
Talimogene laherparepvec is
Amgen
’s cancer immunotherapy. MPDL3280A is
Roche
’s investigational anti-PDL1 therapy. Talimogene is designed to selectively replicate in tumors and cause an immune response to the cancer cells, while not stimulating immune response to normal cells. The company said the theory behind combining the two drugs is to both active an anti-tumor immune response while blocking inhibitory T-cell checkpoints. In other words, they hope to stimulate the body’s immune reaction to the cancer cells while blocking certain activity that puts the brakes on T cells.
“Atezolizumab is our most advanced cancer immunotherapy with 10 ongoing Phase III pivotal trials across lung, bladder, breast and kidney cancers,” said
Sandra Horning
, chief medical officer and head of
Roche
’s
Global Product Development
in a statement. “We are looking forward to working with
Amgen
on this trial, which can inform potential future treatment options for patients affected by very difficult-to-treat tumor types.”
This is not the first collaboration between
Amgen
and
Roche
. In October 2013
Amgen
entered into a
definitive agreement
with
Roche
to buy
Roche
’s rights to filgrastim and pegfilgrastim in about 100 markets.
Roche
held the rights to the two compounds under a license from
Kirin-Amgen, Inc.
, a joint venture between
Amgen
and
Kirin Holdings Co. Limited
, of Japan, for Eastern Europe, Latin America, Asia, the Middle East and Africa since 1989. The two compounds are white blood cell boosting therapeutics.
Amgen
markets them in the U.S. and Europe under the names Neupogen and Neulasta.
Only last week
Amgen announced
an expanded collaboration agreement with
Merck & Co.
to evaluate the safety and efficacy of talimogene laherparepvec in combination with
Merck
’s Keytruda, an anti-PD-1 therapy, in a Phase I trial. The companies also announced a global, randomized Phase III trial to evaluate the combination in patients with regionally or distantly metastatic melanoma.
“We believe that talimogene laherparepvec has potential in several cancer types based on its proposed mechanism of action to initiate tumor antigen release and presentation, important steps in activating a systemic anti-tumor immune response,” said
Sean Harper
, executive vice president of research and development at
Amgen
in a statement.
“Talimogene laherparepvec and Keytruda are designed to result in anti-tumor immune responses through different and potentially complementary mechanisms of action.”
It was noted by analysts in a report published by Moody’s titled “
Biosimilars: Parsing the Industry’s Pipelines
,” that
Roche
,
Amgen
and
AbbVie
are three companies most vulnerable to competition from biosimilars. Specifically,
Amgen
’s Neulasta,
Roche
’s Rituxan and
AbbVie
’s Humira. Biosimilars are a drug that are very similar to known drugs, but which have the same therapeutic action and can be marketed competitively.
Perhaps ironically,
Amgen
’s
pipeline for biosimilars
is one of the most ambitious in the field. “There’s already lots of competition, and we’re used to having to compete on value,” said
Geoff Eich
, executive director of
Amgen
’s biosimilars division in a statement. “This is the natural evolution.”
Although a collaboration between
Amgen
and
Roche
is probably not directly related to biosimilar competition, if
Amgen
’s combination treatment studies with
Roche
and
Merck
are successful, testing for talimogene laherparepvec in combination with other anti-PDL1 therapies may be down the road. In November 2014,
Merck announced
it was working with
Pfizer Inc.
to jointly develop and commercialize MSB0010718C, an investigational anti-PD-L1 antibody for multiple types of cancer.
Will PfizerKline Become the Next Pharma Player?
The speculation surrounding a possible bid from
Pfizer Inc.
for struggling
GlaxoSmithKline
is heating up, after one closely-watched biotech analyst said in a
note last week
that
Pfizer
buying the company would “unlock access to its balance sheet and improve its tax situation.”
Gregg Gilbert
, a biotech analyst at
Deutsche Bank
, wrote in a note to investors “Introducing
PfizerKline
” that he thinks a deal would be “materially accretive” for both companies. Gilbert estimated that a bid priced at $29.86 a share, via half stock and half cash, which would push up
Pfizer
’s earnings per share by 10 percent to 16 percent beginning in 2016.
“We believe that the company has a sense of urgency to create value by leveraging the power of its balance sheet to do needle-moving deals,” Gilbert wrote. “Since media reports in the past have pointed to the potential for a
Pfizer/GSK
combination, we are revisiting that theme.”
We want to know, dear readers, if you agree? Should Glaxo continue going it alone, or might Pfizer buy it and create one of the world’s largest pharma players in history?
