Gilead's Dual-Target CAR-T Therapy Achieves 62% Response Rate in Recurrent Glioblastoma

  • Gilead Sciences' dual-target CAR-T therapy shrank tumors in 62% of patients with recurrent glioblastoma, a rare achievement for this fatal brain cancer.
  • The experimental treatment targets both EGFR and interleukin-13 receptor alpha 2, injected directly into spinal fluid to overcome glioblastoma's multiple tumor cell populations.
  • While responses were encouraging, benefits proved largely temporary with many patients relapsing within two to three months after treatment.
  • Kite is developing a triple-target version to improve persistence and plans to test the therapy in newly diagnosed patients next year.

World-First Clinical Trial Demonstrates Exercise Significantly Improves Colon Cancer Survival

  • A groundbreaking 17-year international clinical trial involving 889 colon cancer patients shows that structured exercise programs reduce cancer recurrence risk by 28% and death risk by 37%.
  • The CO.21 Challenge study, published in the New England Journal of Medicine, is the first clinical trial designed specifically to test whether exercise can improve cancer survival outcomes.
  • Researchers emphasize that exercise should now be considered a standard treatment for colon cancer rather than just a quality-of-life intervention, requiring integration into healthcare systems.
  • The study involved patients with Stage 3 or high-risk Stage 2 colon cancer who completed surgery and chemotherapy, with participants following a 3-year structured exercise program of 2.5 hours weekly moderate-intensity activity.

Johnson & Johnson's Pasritamig Shows Promising Anti-Tumor Activity in First-in-Human Prostate Cancer Trial

  • Johnson & Johnson announced first-in-human Phase 1 results for pasritamig, a novel bispecific T-cell engager targeting KLK2, showing promising anti-tumor activity in metastatic castration-resistant prostate cancer patients.
  • The study demonstrated a favorable safety profile with 40% of patients experiencing no treatment-related adverse events and no treatment discontinuations due to toxicity.
  • Among 33 patients in the efficacy group, 42.4% achieved ≥50% PSA reduction with a median radiographic progression-free survival of 7.9 months.
  • The drug's convenient once-every-six-weeks outpatient dosing schedule represents a potential advantage for community-based cancer care delivery.

Atezolizumab Plus Chemotherapy Reduces Recurrence Risk by 50% in Stage III dMMR Colon Cancer

  • The phase 3 ATOMIC trial demonstrated that adding atezolizumab to standard chemotherapy reduced the risk of recurrence or death by 50% in patients with stage III dMMR colon cancer.
  • Three-year disease-free survival improved significantly from 76.6% with chemotherapy alone to 86.4% with the combination treatment across 712 patients.
  • This represents the first successful immunotherapy adjuvant study in colon cancer and establishes a new standard of care for this patient population.
  • The safety profile was manageable, with only a slight increase in nonfebrile neutropenia compared to known profiles of each individual treatment.

AstraZeneca Advances AZD0022, Novel Oral KRASG12D Inhibitor, in First-in-Human Phase I/IIa Trial

  • AstraZeneca is developing AZD0022, a potent oral KRASG12D-selective inhibitor that demonstrates robust pathway inhibition and anti-tumor activity in preclinical models.
  • The drug is currently being investigated in the ALAFOSS-01 study, a first-in-human Phase I/IIa trial for patients with KRASG12D-mutated solid tumors.
  • Preclinical data shows enhanced therapeutic responses when AZD0022 is combined with cetuximab, with sustained tumor regressions observed in colorectal and pancreatic cancer models.
  • The clinical trial includes both monotherapy and combination therapy modules, targeting multiple cancer types including colorectal, lung, and pancreatic cancers.

Trinity Life Sciences Partners with Ontada to Enhance Real-World Oncology Data Analytics for Drug Development

  • Trinity Life Sciences has formed a strategic collaboration with Ontada, a McKesson business, to provide life sciences companies with real-time oncology insights for pre- and post-launch decision making.
  • The partnership combines Trinity's commercial analytics expertise with Ontada's iKnowMed electronic health record system, which contains data from over 2.4 million patient records across 80+ tumor types.
  • The collaboration aims to accelerate commercial decision-making in community oncology through AI-enhanced analytics and deeper patient journey insights.
  • Ontada's real-world data platform serves more than 2,400 oncology community-based providers across the United States through The US Oncology Network and Onmark practices.

NAPOLI 3 Post-Hoc Analysis Identifies Characteristics Associated with Long-Term Survival in Metastatic Pancreatic Cancer

  • A post-hoc analysis of the Phase III NAPOLI 3 trial identified characteristics associated with long-term survival in metastatic pancreatic adenocarcinoma patients treated with the NALIRIFOX regimen.
  • Long-term survivors (n=15) achieved a median overall survival of 19.5 months, with younger age at diagnosis and specific tumor locations being key factors.
  • Dose modifications and treatment delays enabled patients to receive higher cumulative doses and stay on treatment longer, contributing to improved outcomes.
  • The findings provide important insights for a cancer where fewer than 20% of patients survive longer than one year.

Large-Scale Study Reveals Significant Racial Disparities in Early-Onset Colorectal Cancer Diagnosis

  • A comprehensive analysis of 105,000 colorectal cancer patients found that Black, Hispanic, Latino, and American Indian populations are disproportionately represented in early-onset cases diagnosed before age 50.
  • Early-onset patients were significantly more likely to be diagnosed at advanced stages (III and IV), with a 10 percentage point higher likelihood compared to average-onset patients.
  • Current screening guidelines starting at age 45 fail to cover over half of early-onset patients, particularly those under 44, highlighting the need for risk-based screening approaches.
  • The study revealed diagnostic delays of 4-8 months longer for younger patients, emphasizing the urgent need for reduced time from symptom onset to definitive diagnosis.

Dual Immunotherapy Combination Significantly Extends Survival in Advanced Cutaneous Squamous Cell Carcinoma

  • A phase II clinical trial demonstrated that combining avelumab and cetuximab nearly quadrupled median progression-free survival compared to avelumab alone in patients with advanced cutaneous squamous cell carcinoma.
  • The combination therapy achieved a median progression-free survival of 11.1 months versus 3.0 months for avelumab monotherapy, with a hazard ratio of 0.48 and statistical significance.
  • The study enrolled 57 evaluable patients with advanced cSCC, showing that dual immunotherapy targeting both PD-L1 and EGFR pathways creates synergistic anti-tumor effects.
  • Results provide valuable insights for future trials combining standard-of-care immunotherapies with cetuximab to improve outcomes in this aggressive skin cancer.

Dual-Targeted CAR-T Therapy KITE-363 Shows 87% Response Rate in Relapsed B-Cell Lymphoma

  • KITE-363, a dual CD19/CD20-targeted CAR-T therapy, achieved an 87% objective response rate with 78% complete responses in CAR-T naive patients with relapsed/refractory large B-cell lymphoma.
  • The therapy demonstrated superior CAR-T cell expansion compared to existing treatments, with peak levels 3-5 fold higher than axicabtagene ciloleucel.
  • Safety profile showed manageable toxicity with no grade 3 or 4 cytokine release syndrome or neurotoxicity in primary refractory patients at the recommended dose.
  • Primary refractory patients achieved 80% response rates with 67% complete responses, addressing a critical unmet need in this difficult-to-treat population.
