Overview​

The 48-hour window was dominated by ASCO-related clinical disclosures, with both key developments originating from the Chicago conference. Phanes Therapeutics delivered the most consequential data for investors—a Phase 2 readout in pancreatic cancer that could set up a registrational trial—while the Erbe USA cryoprobe recall represents a rare device-safety signal at the most serious classification level. The tape was light overall, with the editorial note confirming discovery-oriented announcements carried the day rather than any broad sector shift.

Key Developments​

Phanes Therapeutics reported updated Phase 2 data for spevatamig (PT886) in first-line metastatic pancreatic ductal adenocarcinoma (PDAC), revealing a 52.4% objective response rate and 90.5% disease control rate at the 2 mg/kg weekly dose combined with gemcitabine-nab-paclitaxel. The median progression-free survival reached 7.3 months and overall survival 14.7 months in U.S. patients, with manageable hematologic toxicity and no added chemotherapy burden. The dual CLDN18.2/CD47-targeting bispecific antibody—positioned as an innate-immunity enhancer—addresses a tumor type notoriously resistant to checkpoint inhibitors. With FDA Orphan (2022) and Fast Track (2024) designations already in hand, the 3 mg/kg dose cohort remains enrolling and may become the registrational dose. Watch for the formal Phase 3 planning announcement and whether the Merck partnership (2023) yields a pembrolizumab combination arm.

Safety / Pharmacovigilance

Erbe USA initiated a Class I recall of certain Flexible Cryoprobes after identifying a manufacturing defect that causes devices to rupture during activation, resulting in five reported serious injuries including hearing damage and burns. The FDA classified this as the most serious recall tier on March 25, 2026, and the affected product list expanded on May 4 and again on May 28 to include additional lot numbers. The defect traces to insufficient adhesive application during production. Healthcare facilities must quarantine and discontinue use of part numbers 20402-401, 20402-410, and 20402-411 (sizes 1.1mm, 1.7mm, and 2.4mm). Watch for clarification on total unit distribution and whether Erbe has corrected the adhesive process for units still in circulation.

Watchlist​

  • Kelun-Biotech's Phase III OptiTROP-Lung05 demonstrated a 65% reduction in disease progression risk (HR=0.35) for sacituzumab tirumotecan plus pembrolizumab versus pembrolizumab alone in first-line PD-L1-positive advanced NSCLC, with 70.2% ORR and median PFS not yet reached at 10.5 months median follow-up. Results presented at ASCO and simultaneously published in The Lancet. The ADC+IO strategy validated for TROP2 targeting in lung cancer. [link]

  • Kelun-Biotech's pivotal Phase II data for lunbotinib fumarate (A400/EP0031) showed 81.3% ORR in treatment-naïve and 87.1% in pre-treated RET fusion-positive NSCLC patients, including a 30% intracranial complete response rate in 40 patients with CNS metastases.
