Seven questions, 60-second thesis frame.

What changed, and when

Galecto announced on 10 Nov 2025 that it completed the acquisition of Damora Therapeutics and disclosed an oversubscribed private placement of about $285 million, with runway guidance into 2029 (Galecto press release, GlobeNewswire).
The accompanying SEC filing outlines Series B and Series C non-voting convertible preferred stock, lockups, and that the private placement closing is expected on 12 Nov 2025 (SEC Form 8-K). Independent coverage noted a sharp intraday move in GLTO following the news (Investing.com, MarketScreener).

60-second thesis frame

This is a focused hematology pivot around mutant calreticulin MPNs, adding Damora’s DMR-001 and related programs while securing multiyear capital. The near-term value hinge is whether DMR-001’s subcutaneous, half-life-extended profile can replicate or exceed competitor class signals and translate into clean early ET and MF readouts by 2027, with an IND targeted for mid-2026 (Galecto press release, Damora investor presentation, Ex-99.2). Competitive pressure is real, since Incyte’s mutCALR antibody INCA033989 is already in human studies with late-breaking data highlighted at EHA 2025 and an active Phase 1/2 program in ET and MF (Incyte EHA 2025 release, ClinicalTrials.gov NCT05936359).

The seven diligence questions

Clinical

• What head-to-head preclinical data support DMR-001’s claimed potency and how well do those assays predict complete hematologic response, symptom improvement, and CALR VAF reduction in ET or MF, the likely Phase 1/2 signals investors will track (Galecto press release)?
• Can half-life engineering enable low-volume subcutaneous dosing with acceptable immunogenicity and reproducible PK/PD, and will the IND package in mid-2026 include dose-selection evidence that de-risks first-in-human escalation (Damora investor presentation, Ex-99.2)?

Payer or Access

• If successful, is administration clinic-based under the medical benefit or feasible for self-administration at home, and how does that shift coding, buy-and-bill economics, and site-of-care decisions versus oral JAK inhibitors used today?
• What evidence beyond platelet control will major US payers require to credit disease modification in ET or MF, and would a CALR-mutation-defined label narrow or streamline prior authorization compared with current criteria?

Ops or Adoption

• What are the CMC and capacity risks for a half-life-extended antibody intended for low-volume subcutaneous dosing, and is pivotal-scale supply planning aligned with a 2027 proof-of-concept target (Galecto press release)?

Competitive

• How does DMR-001’s target product profile compare with INCA033989 on speed and durability of platelet normalization, biomarker shifts, and tolerability, and what is the strategy if Incyte advances to pivotal ET or MF studies first (Incyte EHA 2025 release, ClinicalTrials.gov NCT05936359)?

Team or Cap table

• Do preferred conversion terms, redomicile, and potential reverse split authority, plus new board additions, constrain or enhance strategic options over the next 12–18 months (SEC Form 8-K)?

Red flags

• If early human signals lag competitor class data on platelet control or CALR VAF reduction, differentiation weakens (Incyte EHA 2025 release).
• Financing optics depend on the private placement closing on 12 Nov 2025 and later stockholder approvals for preferred conversion and related proposals (SEC Form 8-K).
• IND or CMC delays would erode the 2027 proof-of-concept cadence and 2029 runway guidance (Galecto press release).

FAQ

• What exactly changed by Galecto’s announcement of acquisition of Damora Therapeutics on 10 Nov 2025, and why does it matter for MPNs?
  Galecto closed the Damora acquisition and announced an oversubscribed private placement of about $285 million to advance a mutCALR portfolio led by DMR-001, with runway guidance into 2029 (Galecto press release, GlobeNewswire).
• What formal steps follow Galecto’s 10 Nov 2025 announcement in the US and EU?
  The SEC filing indicates stockholder votes will be sought for preferred-to-common conversion, redomicile, and, if needed, a charter amendment that could include reverse split authority, while the financing closing is expected on 12 Nov 2025 (SEC Form 8-K).
• Which endpoints will matter first when DMR-001 enters the clinic after Galecto’s 10 Nov 2025 news?
  Early ET and MF studies typically track safety, platelet normalization, symptom scales, and exploratory biomarkers such as CALR mutant allele burden to suggest disease modification, with competitor precedent informing expectations (ClinicalTrials.gov NCT05936359, Blood perspective on INCA033989).
• What safety issues are most relevant post-Galecto’s and Damora’s deal for a subcutaneous anti-mutCALR antibody?
  Immunogenicity, injection-site reactions, and on-target effects on megakaryopoiesis are key considerations, and the comparator program has reported tolerability in dose escalation with additional EHA 2025 disclosures flagged by the sponsor (Incyte EHA 2025 release).
• How will payers approach access if a mutCALR antibody is eventually approved, and are codes available?
  A clinic-administered biologic would likely bill under the medical benefit with a product-specific HCPCS code once assigned, and prior authorization would be expected to align to CALR mutation status and prior therapies, similar to other mutation-defined oncology biologics, with competitor trial settings offering context (ClinicalTrials.gov NCT05936359).
