In vivo generation of anti-BCMA CAR-T cells in relapsed or refractory multiple myeloma: a phase 1 study

Nature Medicine, Published online: 25 March 2026; doi:10.1038/s41591-026-04244-6

In a phase 1 trial, the in vivo generation of anti-BCMA CAR-T cells by lentiviral delivery was feasible and did not lead to dose-limiting toxicities in five patients with relapsed or refractory multiple myeloma.

Pembrolizumab and olaparib in homologous-recombination-deficient metastatic pancreatic cancer: the phase 2 POLAR trial

Nature Medicine, Published online: 25 March 2026; doi:10.1038/s41591-026-04299-5

Results of the phase 2 POLAR trial show that biomarker-guided treatment in patients with metastatic pancreatic cancer based on homologous repair deficiency leads to encouraging clinical response rates in immune cell-infiltrated tumors.

<i>LRRK2</i>-targeting antisense oligonucleotide in Parkinson’s disease: a phase 1 randomized controlled trial

Nature Medicine, Published online: 24 March 2026; doi:10.1038/s41591-026-04262-4

The first-in-human clinical trial of the LRRK2-targeting antisense oligonucleotide BIIB094 in Parkinson’s disease demonstrates that the treatment is well tolerated and produces dose-dependent reductions in cerebrospinal fluid levels of LRRK2 and phosphorylated Rab10, indicating successful target engagement.

AI-based chest X-ray prioritization in the lung cancer diagnostic pathway: the LungIMPACT randomized controlled trial

Nature Medicine, Published online: 24 March 2026; doi:10.1038/s41591-026-04253-5

In a large UK-based primary care randomized trial, immediate artificial intelligence (AI)-driven prioritization of chest X-rays did not significantly shorten time to computed tomography or lung cancer diagnosis versus standard workflow, suggesting that AI-based prioritization alone is unlikely to accelerate the lung cancer diagnostic pathway.

First-line zolbetuximab plus mFOLFOX6 and nivolumab in unresectable CLDN18.2-positive gastric or gastroesophageal junction adenocarcinoma: a phase 2 trial

Nature Medicine, Published online: 16 March 2026; doi:10.1038/s41591-026-04306-9

In cohort 4 of the ILUSTRO trial, combination of anti-CLDN18.2 zolbetuximab plus mFOLFOX6 and nivolumab in patients with CLDN18.2-positive, HER2-negative metastatic gastric or gastroesophageal junction adenocarcinoma led to encouraging clinical efficacy, supporting the testing of this combination in a phase 3 trial.

  • Modifiable risk factors drive a large share of the global cancer burden
    Nature Medicine, Published online: 13 March 2026; doi:10.1038/s41591-026-04310-zUsing global cancer incidence data from 185 countries, this study shows that four in ten cancers worldwide are attributable to modifiable risk factors. The findings highlight substantial opportunities for prevention through targeted, population-level interventions adapted to regional and sex-specific risk profiles.
     

Modifiable risk factors drive a large share of the global cancer burden

Nature Medicine, Published online: 13 March 2026; doi:10.1038/s41591-026-04310-z

Using global cancer incidence data from 185 countries, this study shows that four in ten cancers worldwide are attributable to modifiable risk factors. The findings highlight substantial opportunities for prevention through targeted, population-level interventions adapted to regional and sex-specific risk profiles.

A structure-based mRNA vaccine for Nipah virus in healthy adults: a phase 1 trial

Nature Medicine, Published online: 12 March 2026; doi:10.1038/s41591-026-04265-1

In this phase 1, open-label dose-escalation study in healthy adults found that the mRNA vaccine (mRNA-1215), encoding the Nipah virus Malaysian strain chimeric pre-fusion F protein linked to glycoprotein G, was safe and induced elevated immune responses at 1 year of follow-up, indicating that this is a promising vaccine candidate for further development.

A cognitive layer architecture to support large-language model performance in psychotherapy interactions

Nature Medicine, Published online: 12 March 2026; doi:10.1038/s41591-026-04278-w

A real-world study showed that introducing a cognitive layer architecture to support specialized psychotherapeutic reasoning capabilities in general-purpose chatbots improved depression and anxiety symptoms compared to chatbots or therapists alone.

A clinical environment simulator for dynamic AI evaluation

Nature Medicine, Published online: 12 March 2026; doi:10.1038/s41591-026-04252-6

The authors propose a framework for clinical AI evaluation within simulated digital hospital environments that capture the evolving constraints, and cascading effects, of clinical decisions.

Blood phosphorylated tau elevation as a biomarker in immunoglobulin light chain and transthyretin amyloidosis

Nature Medicine, Published online: 11 March 2026; doi:10.1038/s41591-026-04272-2

Elevated serum levels of phosphorylated tau are not specific to Alzheimer’s disease and may also serve as a diagnostic tool for the most common types of systemic amyloidosis, with potential utility in distinguishing amyloidosis-related polyneuropathy from polyneuropathy of other etiologies.
