Company moves in value-based care via acquisition and fresh capital
Cityblock Health announced it will acquire rural healthcare provider Homeward Health and simultaneously raised $116 million in a Series E to expand its value-based care model. The combination targets rural and Medicare Advantage populations, an area where care delivery and reimbursement models are increasingly shaped by outcomes and risk adjustment. The deal underlines how digital-first and payer-aligned operators are consolidating provider access while scaling clinically integrated networks. For regional systems and post-acute partners, the Homeward platform could broaden referral and care-management capacity in underserved geographies. Cityblock’s funding provides near-term resources for scaling care operations and technology, positioning it to compete for additional value-based contracts where Medicare Advantage penetration and incentives for longitudinal care management remain key drivers.

Regulatory clearance for Alzheimer’s diagnostics
FDA cleared PrecivityAD2, a blood test intended to evaluate Alzheimer’s disease risk by detecting amyloid pathology. The test, developed with technology pioneered at Washington University School of Medicine in St. Louis, received authorization for marketing as an aid in clinical evaluation. The clearance is notable because it expands access to amyloid assessment beyond imaging and lumbar procedures, potentially reducing time-to-information in diagnostic pathways. In practice, clinicians may use the test to help stratify patients for further workup or treatment planning. For biotech and diagnostics developers, the move also reinforces continued regulatory momentum for blood-based biomarkers that target core Alzheimer’s pathology.

Immuno-oncology regulatory milestone in China
China’s NMPA accepted the NDA for opamtistomig (LBL-024) as monotherapy for previously treated advanced extrapulmonary neuroendocrine carcinoma. The agency’s Center for Drug Evaluation granted priority review, with the filing supported by a registrational study led by Lin Shen, MD, of Peking University Cancer Hospital. The program targets PD-L1 and 4-1BB via a bispecific antibody designed to conditionally activate 4-1BB signaling while blocking PD-1/PD-L1 immune suppression. Opamtistomig has previously received breakthrough therapy designation, and earlier reported results cited an ORR of 33.3% in EP-NEC. If approved, it would represent the first marketed therapy directly targeting 4-1BB, adding another immuno-oncology mechanism for a disease area described as lacking approved options globally.

Clinical evidence for early-stage HER2-directed treatment
NeoZanHER, a phase 2 trial, reported early-stage activity for zanidatamab in patients with HER2-positive breast cancer treated before surgery. Presented as the first look at a preoperative strategy using a next-generation antibody designed to engage the HER2 receptor through two distinct mechanisms, the study evaluates the approach in a window where pathological response can guide future development. Published in Nature Communications in 2026, the trial was led by the study team in its NeoZanHER phase 2 cohort and focuses on the disease biology of HER2-driven tumors in the neoadjuvant setting. The pre-surgical model is often used to test whether immune and tumor-directed pharmacology translates into measurable tumor reduction. For pipeline decision-making, the key question is whether the regimen can deliver robust response signals that support progression into larger registration efforts and broader HER2-positive subgroups.

Advances in molecular targeting of hard-to-treat cancer
Researchers at Stanford Medicine developed TCIP3, a two-headed experimental therapy that converts a cancer driver into a built-in kill switch rather than simply inhibiting or destroying the protein. The approach eliminated aggressive human lymphoma tumors in mouse models by reprogramming the target’s function into an anti-tumor state. The study describes a strategy that aims to maintain specificity while shifting downstream cellular outcomes toward death. Mechanistically, “molecular glue” concepts depend on inducing new interactions; TCIP3’s reported tumor eradication suggests the circuit is effective in vivo for lymphoma. If this translates beyond preclinical models, TCIP3-style conversion could become a platform for hard-to-drug oncogenic drivers where conventional inhibition produces limited durability.
