FLORHAM PARK, N.J., May 04, 2022 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal diseases, today announced a revenue interest financing of up to $260 million in non-dilutive capital. The agreement provides for an upfront $100 million cash payment and an additional $160 million cash payment upon FDA approval of vonoprazan for treatment of EE.

“The signing of this agreement both validates our belief in the blockbuster opportunity of vonoprazan and provides near-term, non-dilutive funding for our continued development activities and upcoming commercial launch. The next twelve months are pivotal for Phathom as we prepare for the U.S. launch of vonoprazan for H. pylori in the third quarter of this year, followed by the potential FDA approval for erosive esophagitis expected in the first quarter of 2023,” said Terrie Curran, President and Chief Executive Officer of Phathom. “Based on our current operating plan, and with the funds from today’s transaction plus our cash on hand and access to capital under our existing loan agreement, we believe we have sufficient capital to fund operations through 2024. This includes supporting the launch of vonoprazan for H. pylori and in EE, if approved, in addition to financing our daily dosing Phase 3 trial in NERD. We are thrilled to partner with firms who share our belief in Phathom’s significant opportunity and mission to improve the treatment landscape for acid-related disorders.”

Sagard Healthcare Partners (“Sagard”), NovaQuest Capital Management (“NovaQuest”) and Hercules Capital, Inc. (NYSE: HTGC) (“Hercules”) (collectively, “the Investors”) have committed to providing $260 million, including the first $100 million payment and commitments for an additional $160 million upon EE approval. The agreement provides Phathom with an option, subject to the Investors’ right of first offer, to increase the payments under the agreement to up to $300 million by adding additional investors for up to an additional $40 million.

In exchange for the commitment to provide these cash payments, the Investors will receive a 10% royalty on Phathom’s net sales of products containing vonoprazan. The royalty payment will be reduced to 1% on incremental net sales that exceed certain annual thresholds following regulatory approval of vonoprazan for symptomatic non-erosive reflux disease, or NERD. The total royalties payable by Phathom to the Investors are capped at 2.0x of the total payments received from the investors. Upon achievement of the cap amount, the royalty agreement will terminate.

Morgan Stanley & Co. LLC acted as sole structuring agent on the transaction. Morgan, Lewis & Bockius LLP served as legal counsel to Phathom. Pillsbury Winthrop Shaw Pittman LLP served as legal counsel to the Investors.
