Material changes versus the prior comparable periods
- Research and development expense increased by $16.4 million in Q3 and $28.2 million for the nine-month period, primarily because of the pivotal lorundrostat program, clinical supply and manufacturing costs, increased headcount, and a $4.0 million Mitsubishi Tanabe development milestone recorded during the nine months.
- General and administrative expense increased by $2.4 million in Q3 and $7.2 million for the nine-month period, reflecting higher public-company professional fees, compensation, insurance, and administrative costs.
- Interest income increased by $2.8 million in Q3 and $8.7 million for the nine-month period due to the substantially larger investment portfolio following the IPO.
- In February 2023, the company completed its IPO of 13.8 million shares at $16.00 per share, generating approximately $201.4 million of net proceeds. Existing preferred stock converted into 20.6 million common shares upon the IPO.
- Common shares outstanding increased to 41.1 million at September 30, 2023 from 6.4 million at December 31, 2022, primarily because of the preferred-stock conversion and IPO.
Guidance, outlook, risks, contingencies, and unusual items
- Clinical outlook: Advance-HTN, a Phase 2 pivotal hypertension trial, began in April 2023, with topline data expected in the second half of 2024. Launch-HTN, a planned Phase 3 trial, was expected to begin in the second half of 2023, with topline data expected in the second half of 2025.
- The company planned to initiate the Explore-CKD Phase 2 trial in the second half of 2023, with topline data anticipated between the fourth quarter of 2024 and first quarter of 2025.
- Management expects substantial increases in research and development and general and administrative expenses and continuing operating losses and negative operating cash flow for the foreseeable future.
- Management believes existing cash, cash equivalents, and investments will fund operations for at least twelve months from the financial statement issuance date, but the estimate depends on clinical-development timing, costs, regulatory outcomes, and other assumptions.
- Additional funding will likely be required through equity, debt, collaborations, licensing, or other sources. No committed external funding source exists; future financing could be unavailable, costly, or dilutive.
- Under the Mitsubishi Tanabe license, the next anticipated development milestone is $5.0 million upon initiation of the Launch-HTN trial. The agreement also includes potential additional development and commercial milestones and tiered royalties ranging from the mid-single digits to 10% of net sales.
- No material legal proceedings were pending or threatened. Management reported no material changes to previously disclosed risk factors and concluded that disclosure controls were effective as of September 30, 2023.
