-Dordaviprone addresses a significant unmet
patient need for patients with rare, high-grade brain
tumors-
-Transaction to add near-term
commercial opportunity to Jazz's pipeline-
-Transaction represents total cash
consideration of approximately $935
million, or $8.55 per
share-
DUBLIN and DURHAM,
N.C., March 5, 2025 /PRNewswire/ -- Jazz
Pharmaceuticals plc (Nasdaq: JAZZ) ("Jazz" or the "Company") and
Chimerix (Nasdaq: CMRX) ("Chimerix"), today announced the companies
have entered into a definitive agreement for Jazz to acquire
Chimerix for $8.55 per share in cash,
representing a total consideration of approximately $935 million. The transaction has been approved
by both companies and is expected to close in the second quarter of
2025.

Chimerix's lead clinical asset is dordaviprone, a novel
first-in-class small molecule treatment in development for H3
K27M-mutant diffuse glioma, a rare, high-grade brain tumor that
most commonly affects children and young adults. There are no U.S.
Food and Drug Administration (FDA)-approved therapies specifically
for H3 K27M-mutant diffuse glioma patients; radiation is the most
common treatment approach. A New Drug Application (NDA) for
accelerated approval of dordaviprone in recurrent H3 K27M-mutant
diffuse glioma was recently accepted and granted Priority Review by
FDA. FDA has set a target Prescription Drug User Fee Act (PDUFA)
action date of August 18, 2025. If
approved in the U.S., dordaviprone may be eligible for a Rare
Pediatric Disease Priority Review Voucher (PRV). Separately,
dordaviprone is being studied in the ongoing Phase 3 ACTION trial,
evaluating its use in newly diagnosed, non-recurrent H3 K27M-mutant
diffuse glioma patients following radiation treatment, potentially
extending this treatment option into the front-line setting.
"Adding dordaviprone to our oncology R&D pipeline will
further diversify our portfolio with a medicine that addresses a
significant unmet need with no other FDA-approved therapies and
limited treatment options for this patient population. If approved,
dordaviprone has the potential to rapidly become a standard of care
for a rare oncology disease and also contribute durable revenue
beginning in the near-term," said Bruce
Cozadd, chairman and chief executive officer, Jazz
Pharmaceuticals. "We are encouraged by the dordaviprone clinical
trial results to date and look forward to closing the proposed
acquisition and working with our new colleagues from Chimerix to
fully leverage our combined R&D and commercial expertise to
deliver this novel therapy to patients, beginning as early as the
second half of this year."
"We are excited to reach this agreement with Jazz
Pharmaceuticals as they bring global scale to broaden our
dordaviprone commercial strategy," said Mike Andriole, President and CEO of Chimerix.
"The transaction, if approved, provides the opportunity to advance
access to dordaviprone to reach more patients globally. This
announcement is the culmination of years of scientific work by our
incredibly talented team, and will deliver significant and certain
value to our shareholders."
Key Highlights
- Strategic fit that will strengthen Jazz's presence in the rare
oncology space and reinforces commitment to patients with rare
diseases with significant unmet need
- Dordaviprone has been shown to benefit patients with recurrent
H3 K27M-mutant diffuse glioma across several clinical studies, with
a consistently favorable safety profile both as monotherapy and in
combination with other treatment approaches including
radiation
- With no currently approved therapies for H3 K27M-mutant diffuse
glioma patients, dordaviprone has the potential to rapidly become a
standard of care and a meaningful therapy for patients with limited
treatment options
- Potential near-term commercial launch in the U.S., if approved
- FDA has accepted an NDA for dordaviprone seeking accelerated
approval for treatment of H3 K27M-mutant diffuse glioma in adult
and pediatric patients with progressive disease following prior
therapy
- NDA has been granted Priority Review and assigned a PDUFA
target action date of August 18, 2025
- Following the closing of the proposed acquisition and in
collaboration with its new colleagues from Chimerix, Jazz plans to
leverage its combined development and commercial capabilities to
continue advancing the dordaviprone clinical trial program and
execute a strong commercial launch, if approved in the U.S.
- Will create an additional durable revenue opportunity for Jazz
with patent protection into 2037, with potential to receive patent
term extension
- Ongoing Phase 3 ACTION trial has potential to confirm clinical
benefit of dordaviprone in recurrent H3 K27M-mutant diffuse glioma
and extend its use to front-line patients
Transaction Terms
Under the terms of the merger
agreement, Jazz will commence an all-cash tender offer to acquire
all outstanding shares of Chimerix's common stock, whereby Chimerix
shareholders will be offered $8.55
per share in cash, representing a total consideration of
approximately $935 million. This
reflects an approximately 72% premium based on the closing trading
price on March 4, 2025. Upon the
successful completion of the tender offer, Jazz will acquire all
shares not acquired in the tender through a second-step merger for
the same consideration per share paid in the tender offer.
Jazz expects to fund the transaction through existing cash and
investments.
Closing Conditions
The transaction is subject to
customary closing conditions, including the tender of a majority of
the outstanding shares of Chimerix's voting common stock and other
conditions. Chimerix's Board of Directors unanimously recommends
that Chimerix shareholders tender their shares in the tender
offer.
