- Proceeds from strategic financing together with year-end cash resources expected to fund operations into mid-2025 including etripamil NDA submission and launch in PSVT
- The combination of etripamil's strong clinical results with this strategic financing lays the foundation to deliver a therapy that empowers patients to treat supraventricular tachycardia attacks outside the emergency department
MONTREAL and CHARLOTTE, N.C., March 28, 2023 /PRNewswire/ -- Milestone Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced that it has entered into a $125 million strategic funding agreement with existing shareholder, RTW Investments, LP and certain of its affiliates ("RTW"). Proceeds from this tailored financing, together with $64.6 million of cash, cash equivalents and short-term investments as of December 31, 2022, are expected to fund Milestone's operations into the middle of 2025, including the potential approval and launch of etripamil. Etripamil is the Company's investigational calcium channel blocker envisioned to empower patients with paroxysmal supraventricular tachycardia (PSVT) to treat their attacks outside of the emergency department.
The strategic financing was anchored by RTW's purchase of $50 million in convertible notes, as well as a commitment of $75 million in non-dilutive royalty funding, which, together, the Company expects will support the NDA submission and subsequent launch of etripamil for patients with PSVT. If approved, etripamil is intended to give health care providers a new tool to enable patient self-management. Etripamil has the potential to provide the patient with a greater sense of control over their PSVT, a condition marked by highly symptomatic, unpredictable, and burdensome episodes of cardiac arrhythmia. The Company plans to submit a New Drug Application to the U.S. Food and Drug Administration in the third quarter of 2023.
"Etripamil has demonstrated strong potential to offer patients a meaningful intervention for the treatment of PSVT outside of the costly and inconvenient acute-care setting and we are highly encouraged by the results of the Phase 3 RAPID study in October 2022," said Roderick Wong, MD, Managing Partner and Chief Investment Officer of RTW Investments, LP. "We are excited to expand our partnership with the convertible note and royalty financings to continue to support Milestone's effort to advance etripamil to a potential U.S. regulatory approval and future commercialization efforts."
"As we continue on our mission of delivering this much needed therapeutic option to patients suffering from episodic cardiovascular conditions, it is a privilege to partner with RTW on these strategic financings, which we believe further validate the value of etripamil," said Amit Hasija, Chief Financial Officer and Executive Vice President of Corporate Development at Milestone.
RTW has extended its investment relationship with Milestone by purchasing $50 million of senior secured convertible promissory notes (the "Notes") in a private placement transaction. The Notes are convertible into common shares of Milestone at an initial conversion price of $5.23 per share, which represents a 50% premium over the volume-weighted average price of Milestone's common shares over the trailing 30-trading day period ending on March 27, 2023. Funds from the Notes will be immediately available upon closing.
The Notes will be senior secured obligations of Milestone and will accrue interest at a rate of 6.0% per annum, payable quarterly in arrears, with the option to be paid in kind for the first three years at Milestone's election. The Notes will mature on March 31, 2029, unless earlier redeemed, converted or repurchased. Holders will have the right to convert their Notes at any time prior to the close of business on the second trading day immediately preceding the Notes' maturity date. Milestone will settle conversions solely in shares of its common shares, except for payments of cash in lieu of fractional shares.
In addition, under the terms of the revenue financing agreement, subject to customary closing conditions and subject to FDA approval of etripamil, RTW provided a $75 million non-dilutive synthetic royalty financing commitment to Milestone in return for tiered rate, cash royalty payments based on aggregate net sales of etripamil within the United States. RTW will receive royalty rates ranging from high to low single digits based on certain annual sales thresholds, subject to upward adjustment if certain annual sales thresholds are not met. Royalty funds become available upon FDA approval of etripamil for PSVT, and satisfaction of other customary conditions.
The offer and sale of the Notes and any common shares issuable upon conversion of the Notes have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any other securities laws, and the Notes and any such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the Notes or any common shares issuable upon conversion of the Notes, nor will there be any sale of the Notes or any such common shares, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful.
Cowen acted as financial advisor to Milestone on the financing transactions. Cooley acted as legal advisor to Milestone. Gibson Dunn acted as legal advisor to RTW.
