Q2 2025 earnings summary14 Aug, 2025

Executive summary

  • Advanced BDC-4182 (claudin 18.2 ISAC) into Phase 1 for gastric/gastroesophageal cancer, with enrollment started in April 2025 and initial data expected in H1 2026.

  • BDC-3042 (dectin-2 agonist) completed Phase 1, showing promising results in lung cancer; seeking a partner for further development.

  • May 2024 restructuring prioritized pipeline, discontinued trastuzumab imbotolimod and BDC-1001, and reduced workforce by 50%.

  • Collaborations with Toray, Genmab, and Innovent continue to provide revenue and pipeline expansion opportunities.

Financial highlights

  • Collaboration revenue was $1.8M for Q2 2025 (up $0.5M YoY) and $3.0M for H1 2025 (down $3.5M YoY due to Innovent revenue recognition in 2024).

  • Net loss was $8.6M for Q2 2025 (improved from $21.2M YoY) and $19.6M for H1 2025 (improved from $32.0M YoY); net loss per share was $(4.46) for Q2 2025.

  • R&D expenses decreased to $7.5M in Q2 2025 (from $15.4M YoY), mainly due to program discontinuation and lower salaries.

  • G&A expenses were $3.5M in Q2 2025 (down from $4.9M YoY) and $7.3M in H1 2025 (down from $10.7M YoY).

  • Cash, cash equivalents, and marketable securities totaled $48.5M as of June 30, 2025.

Outlook and guidance

  • Cash and equivalents expected to fund operations through mid-2026, but substantial doubt exists about ability to continue as a going concern without additional capital.

  • Initial data from BDC-4182 Phase 1 anticipated in H1 2026; expansion to additional countries planned in H2 2025.

  • Ongoing efforts to secure partnerships or raise capital; future funding needs will grow with clinical advancement.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

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.
