Shenzhen-based QuantumPharm Inc., known as Xtalpi Inc. (HKG: 2228) disclosed that its wholly‑owned subsidiary Ailux has entered a multi‑year collaboration with Eli Lilly and Company (NYSE: LLY). The agreement is valued at USD 345 million, with upfront and near‑term cash payments running into the double‑digit‑million range.

Deal Highlights

ItemDetails
PartiesXtalPi’s AI‑driven antibody platform (Ailux) – Eli Lilly
Total ValueUSD 345 million (up‑front + milestone payments)
Up‑Front CashDouble‑digit‑million USD paid at signing
ScopeAccess to Ailux’s engineering platform for bispecific antibody programs across multiple therapeutic targets; optional license of Ailux’s AI‑driven discovery engine for Lilly’s internal use
Historical ContextLilly previously partnered with XtalPi in 2023 on a small‑molecule discovery program worth up to USD 250 million
Commercial TimelineFirst target selection expected Q2 2026; IND‑enabling studies to begin Q4 2026

Strategic Rationale

  1. Accelerated Antibody Innovation – Ailux’s proprietary engineering platform integrates AI‑guided sequence design, rapid in‑silico affinity maturation, and high‑throughput expression, shortening bispecific antibody development cycles from years to months.
  2. Portfolio Diversification for XtalPi – Moving beyond small‑molecule discovery, the partnership expands XtalPi’s addressable market into the high‑margin biologics space, leveraging its AI core across modalities.
  3. Lilly’s Pipeline Enrichment – The collaboration provides Lilly with a ready‑made platform to generate next‑generation bispecifics for oncology, immunology, and rare diseases, complementing its existing antibody assets.

Financial & Market Impact

  • Revenue Outlook – The upfront cash bolsters XtalPi’s cash runway into 2027, while milestone‑linked payments could lift FY 2026‑2028 revenue by ~ 15 % on a pro‑forma basis.
  • Valuation Upside – Analysts have upgraded XtalPi’s price target by 9 % following the announcement, citing the “high‑value, AI‑enabled biologics” narrative.
  • Competitive Landscape – The deal places XtalPi among a select group of AI‑driven biotech firms (e.g., Insilico, Exscientia) that have secured large‑scale antibody collaborations with top‑tier pharma.

Outlook & Next Steps

  • Target Identification – Ailux will present up to four bispecific candidates to Lilly by the end of Q2 2026, covering oncology (e.g., HER2 × PD‑L1) and immunology (e.g., IL‑23 × IL‑17).
  • Regulatory Path – Early‑phase IND filings are slated for 2027, with potential Fast‑Track designations for oncology programs.
  • AI Platform License – Lilly retains an option to license Ailux’s AI engine for internal discovery, a decision expected in early 2026 after a six‑month pilot.
