Executive summary

  • Orlynvah (oral sulopenem) launched in the U.S. in August 2025 for uncomplicated urinary tract infections, marking the first new branded launch in this space in over 25 years and targeting adult women with limited treatment options.

  • Over 280 prescriptions were generated by more than 100 unique prescribers through November 12, with nearly half prescribing to multiple patients, indicating growing physician comfort and repeat use.

  • Commercial efforts include both in-person and virtual sales representatives, with a reduction in field team size offset by virtual augmentation to maintain or exceed coverage in at least 20 target geographies.

  • Customer feedback highlights Orlynvah’s value in treating resistant infections and keeping patients out of the hospital, with strong interest from infectious disease specialists.

  • FDA approval was received in October 2024, and the company is focused on maximizing Orlynvah’s commercial potential and expanding its sulopenem program.

Financial highlights

  • Net product revenue for Q3 2025 was $0.4 million, reflecting initial stocking and early sales post-launch.

  • Net loss (GAAP) was $9 million in Q3 2025, compared to $6.1 million in Q3 2024; non-GAAP net loss was $7.3 million versus $4.8 million year-over-year.

  • Operating expenses rose to $8.1 million in Q3 2025 from $4.9 million in Q3 2024, driven by commercialization activities.

  • Cash and cash equivalents stood at $11 million at the end of September 2025, with an additional $2.6 million raised post-quarter.

Outlook and guidance

  • Full-year 2026 net product revenue is expected to be between $5 million and $15 million, with operating expenses projected at $25–$30 million.

  • Cash runway is expected to last into Q2 2026, including proceeds from recent fundraising.

  • Additional capital will be required to continue commercialization through 2026, with plans to seek shareholder approval for further share issuance.

  • Management expects continued significant operating losses as commercialization and development activities expand.

  • Substantial doubt exists about the ability to continue as a going concern without additional funding.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
