NEW YORK – – October 21, 2020 – Nuvation Bio, Inc., a biopharmaceutical company focused on revolutionizing cancer treatment by discovering, developing and delivering therapies that tackle some of the greatest needs in oncology, and Panacea Acquisition Corp. (NYSE: PANA), a special purpose acquisition company (SPAC) sponsored by EcoR1 Capital, today announced they have entered into a definitive business combination agreement. Upon closing of the transaction, Panacea will be renamed Nuvation Bio Inc. (the Combined Company); its common stock is expected to remain listed on the New York Stock Exchange (NYSE) under the new ticker symbol “NUVB.”

“Nuvation Bio is developing novel oncology therapeutic agents for some of the most difficult-to- treat cancers, specifically targeting indications for which conventional therapies have failed. To that end, we have created a deep portfolio of six promising oncology therapeutic candidates that target some of the most critical pathways that cancer cells use to grow. We have demonstrated, in preclinical studies, the potential of those candidates to significantly improve outcomes over current standards of care,” said David Hung, M.D., founder and chief executive officer of Nuvation Bio. “Our goal is to develop new generations of oncology medicines that will meaningfully improve patient lives by addressing drug resistance or limited efficacy of current therapies, while reducing side effects and preserving quality of life for cancer patients. The large financing that we will secure with this SPAC merger provides us with the capital we need to advance that goal.”

In addition to the approximately $144 million held in Panacea’s trust (assuming no redemptions), a group of premier healthcare investors has committed to participate in concurrent equity financings totaling slightly more than $500 million at $10 per share. Investors include lead investor EcoR1 Capital, an existing Nuvation Bio shareholder that has committed to invest $50 million, including its $25 million forward purchase agreement, as well as new investors 683 Capital, Ally Bridge Group, Avidity Partners, Deerfield Management Company, Irving Investors, Monashee Investment Management LLC, OrbiMed, Wellington Management, and other existing Nuvation Bio shareholders including The Baupost Group, Boxer Capital of the Tavistock Group, Fidelity Management & Research Company, LLC, Omega Funds, Perceptive Advisors, Redmile Group, and Surveyor Capital (a Citadel Company).

The Combined Company is expected to have cash resources of more than $850 million at the closing of the transaction (assuming no redemptions) and will continue to operate under the Nuvation Bio executive team, led by Dr. Hung. The Boards of Directors of both Panacea and Nuvation Bio have approved the proposed transaction. Completion of the transaction, which is expected in the first quarter of 2021, is subject to approval of both companies’ shareholders and the satisfaction or waiver of certain other customary closing conditions, including expiration of the Hart-Scott-Rodino Act waiting period.

“We formed Panacea to partner with a company that had an exceptional management team, a deep pipeline, and a platform technology that could enable success to be replicated over and over, and that is exactly what we saw in Nuvation Bio,” said Oleg Nodelman, chief executive officer of Panacea. “Nuvation Bio is led by a proven entrepreneurial CEO who was responsible for developing and commercializing one of the most successful prostate cancer medicines, each of its early-stage programs is designed to target multiple cancers, and all of its planned therapies are based on validated targets that are biologically active. We believe Nuvation Bio has what it takes to develop multiple successful oncology medicines that will provide true medical innovation for patients.”

Nuvation Bio will use the proceeds of the business combination and concurrent equity financings, together with its existing cash resources, to advance into clinical development up to six compounds that have resulted from its drug discovery and development programs. These programs include a cyclin-dependent kinase (CDK) inhibitor program, a BET inhibitor program, a WEE1 inhibitor program, an adenosine A2A receptor inhibitor program, and a drug-drug conjugate (DDC) platform that to date has yielded investigational compounds targeting hormone-driven cancers, such as prostate, breast and ovarian cancers. The U.S. Food and Drug Administration (FDA) recently accepted Nuvation Bio’s first Investigational New Drug (IND) application, and Nuvation Bio plans to initiate enrollment in a Phase 1/2 study of its lead investigational compound, NUV-422, a CDK2/4/6 inhibitor, in patients with high-grade gliomas, including glioblastoma multiforme (GBM), by the first quarter of 2021. Nuvation Bio anticipates submitting up to five additional INDs by 2026 for therapies targeting some of the most difficult- to-treat solid tumors and hematologic cancers.

Founded in 2018, Nuvation Bio has assembled strong management and scientific teams led by Dr. Hung, an oncologist and biopharma industry veteran. Dr. Hung previously founded Medivation, Inc., which developed XTANDI ® (enzalutamide), one of the world’s leading prostate cancer medicines, and talazoparib (now marketed as TALZENNA ® ), a novel PARP inhibitor for the treatment of breast cancer. Medivation was acquired by Pfizer in 2016 for $14.3 billion in an all-cash deal.

The team that discovered and developed Nuvation Bio’s compounds includes chemists who worked at Medivation and took XTANDI from first in vitro laboratory experiment to FDA approval in seven years – one of the fastest development timelines in pharmaceutical history. In addition to Medivation, Nuvation Bio’s management team comprises biopharma industry veterans who have contributed to drug discovery, development and commercialization at a number of other biopharmaceutical companies, including Clovis Oncology, Eli Lilly, Johnson & Johnson, Millennium Pharmaceuticals, Radius Health and Roche. Dr. Hung, together with the team of chemists from Medivation, invented all of the programs in Nuvation Bio’s current pipeline, which are wholly owned and controlled by Nuvation Bio.

The Combined Company’s Board of Directors is expected to consist of one director designated by Panacea plus existing Nuvation Bio directors Daniel Welch (Chair), Robert Bazemore, Kim Blickenstaff, Kathryn Falberg, David Hung, M.D., and W. Anthony Vernon. Michelle Doig of Omega Funds will remain on the Board during a transition to be completed by June 1, 2021.
