Clinical, Regulatory, and Business Updates:
| • | | In June 2023, Phathom submitted a PAS to the FDA for both VOQUEZNA TRIPLE PAK (vonoprazan, amoxicillin, clarithromycin) and VOQUEZNA DUAL PAK (vonoprazan, amoxicillin). The submission of these supplements signifies a full response to the February 2023 complete response letter (CRL) and, subject to filing, the FDA has assigned a PDUFA goal date of October 30, 2023. The PAS contained three months of stability data supporting both VOQUEZNA-based convenience packs, which includes reformulated vonoprazan tablets, to support the commercial shelf life of vonoprazan. Phathom plans to provide six-month stability data during the regulatory review as previously agreed with the FDA. |
| • | | In June 2023, Phathom announced that the FDA acknowledged the New Drug Application (NDA) resubmission for vonoprazan for the treatment of Erosive GERD (gastroesophageal reflux disease) constitutes a complete response to the February 2023 CRL and assigned a PDUFA goal date of November 17, 2023. |
| • | | In May 2023, Phathom recorded $141.4 million in net proceeds from the completed public offering of its common stock. The total gross proceeds to Phathom from the offering were approximately $150.3 million, before deducting the underwriting discounts and commissions and other offering expenses. Phathom intends to use the net proceeds from the offering to fund the clinical development of vonoprazan, pre-commercial activities and commercialization expenses, and for working capital and general corporate purposes. |
