CHESTERBROOK, PA., Oct. 30, 2020 (GLOBE

NEWSWIRE) -- Trevena, Inc. (Nasdaq: TRVN), a biopharmaceutical company focused on the development and commercialization

of novel medicines for patients with central nervous system (CNS) disorders, today announced that oliceridine has been classified

as a Schedule II controlled substance by the U.S. Drug Enforcement Administration (DEA). With DEA scheduling now complete, the

Company expects to make OLINVYK available for distribution in November.

"I am pleased that OLINVYK is

now an FDA approved and scheduled product - two major milestones achieved in 2020," said Carrie Bourdow,

President and Chief Executive Officer of Trevena, Inc. "We made the decision earlier this year to begin manufacturing

commercial product, so that physicians could have access to OLINVYK for their hospitalized acute pain patients as soon as

possible upon approval and DEA scheduling. We look forward to making OLINVYK available for ordering in November."

Each year, approximately 45 million hospital

patients in the United States receive drugs like IV morphine to treat their acute pain. OLINVYK is an IV opioid that is the first

new chemical entity in this drug class in decades and is distinct from drugs like IV morphine. OLINVYK has no active metabolites

and requires no dosage adjustment in renal-impaired patients, a large patient population with significant medical complications.

In addition, OLINVYK delivers IV opioid efficacy with a rapid 2-5 minute onset of action.

OLINVYK was studied in over 1,500 patients,

including medically complex patients such as the elderly and obese, and across a variety of surgical procedures.

As a new chemical entity, OLINVYK was required

to be scheduled by the DEA following its approval by the FDA in August 2020. A Schedule II

assignment applies to drugs that should only be administered by a healthcare professional in controlled clinical settings. All

current IV opioids used in the hospital setting are classified

as Schedule II substances.

The Company also today announced cash and

cash equivalents of $112.7 million as of September 30, 2020, which the Company expects will be sufficient to fund operating expenses,

including the commercialization of OLINVYK, through year-end 2022.

About OLINVYK (oliceridine) injection

OLINVYK is a new chemical entity approved

by the FDA in August 2020. OLINVYK contains oliceridine, a Schedule II controlled substance with a high potential for abuse similar

to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, oxymorphone, and tapentadol.

It is indicated in adults for the management of acute pain severe enough to require an intravenous opioid analgesic and for whom

alternative treatments are inadequate. Please see Important Safety Information, including the BOXED WARNING, and full prescribing

information at www.OLINVYK.com.

Trevena, Inc. is a biopharmaceutical company

focused on the development and commercialization of novel medicines for patients with CNS disorders. The Company has one approved

product in the United States, OLINVYK (oliceridine) injection, indicated in adults for the management of acute pain severe

enough to require an intravenous opioid analgesic and for whom alternative treatments are inadequate. The Company also has four

novel and differentiated investigational drug candidates: TRV250 for the acute treatment of migraine, TRV734 for maintenance treatment

of opioid use disorder, and TRV027 for acute lung injury / abnormal blood clotting in COVID-19 patients. The Company has also identified

TRV045, a novel S1P receptor modulator that may offer a new, non-opioid approach to treating a variety of CNS disorders.
