Rinatabart Sesutecan Shows Promise in Heavily Pretreated Ovarian Cancer

  • Rinatabart sesutecan (Rina-S) demonstrated a 50% objective response rate in heavily pretreated ovarian cancer patients at a 120 mg/m2 dose.
  • Responses to Rina-S were observed across varying levels of folate receptor-alpha (FRα) expression, indicating broad potential.
  • A Phase 3 trial is planned to further assess the safety and efficacy of Rina-S at 120 mg/m2 in advanced ovarian cancer patients.
  • The Phase 1/2 trial showed manageable safety profile with infrequent dose reductions and no ocular toxicities, neuropathy, or ILD.

Lantheus' 177Lu-PNT2002 Shows Promise in Metastatic Castration-Resistant Prostate Cancer

  • Lantheus' 177Lu-PNT2002 met its primary endpoint in the SPLASH Phase 3 trial, demonstrating a significant improvement in radiographic progression-free survival compared to ARPI switch.
  • The trial showed a 38.1% Overall Response Rate for 177Lu-PNT2002 versus 12.0% for the ARPI switch arm, including a 9.3% Complete Response rate.
  • Patients treated with 177Lu-PNT2002 experienced a statistically significant improvement in time to reduction of health-related quality of life.
  • Interim Overall Survival data, adjusted for crossover, showed a hazard ratio of <1.00, suggesting a potential survival benefit with 177Lu-PNT2002.

Long-Term Data Show Durable Benefit of Immunotherapy in Metastatic Melanoma

  • A decade-long follow-up of the CheckMate 067 trial reveals that roughly half of metastatic melanoma patients treated with nivolumab and ipilimumab remain cancer-free.
  • The combination therapy demonstrates a sustained efficacy and safety profile, with no new long-term toxicity signals observed over the 10-year period.
  • The findings suggest that patients progression-free at three years have a high likelihood of remaining alive and disease-free at the 10-year mark.
  • Researchers suggest the long-term success may allow for reduced follow-up frequency for patients doing well after three to five years.

Cabozantinib/Atezolizumab Fails to Meet OS Endpoint in mCRPC, Regulatory Submissions Limited

  • The Phase III CONTACT-02 trial evaluated cabozantinib plus atezolizumab versus a second novel hormonal therapy in metastatic castration-resistant prostate cancer (mCRPC).
  • While the combination showed a positive trend in overall survival (OS), it did not reach statistical significance (HR: 0.89; 95% CI: 0.72-1.10; P=0.296).
  • Ipsen will not pursue regulatory submissions for the cabozantinib/atezolizumab combination in mCRPC in countries outside the US and Japan, despite a statistically significant PFS benefit.
  • The combination demonstrated a statistically significant benefit in progression-free survival (PFS) and showed promising OS benefit in patients with liver and bone metastases.

Keytruda Shows Sustained Survival Benefit in Advanced Melanoma After 10 Years

  • Ten-year follow-up data from the KEYNOTE-006 trial demonstrates a sustained overall survival (OS) benefit for Keytruda (pembrolizumab) compared to ipilimumab in advanced melanoma.
  • The 10-year OS rate for Keytruda was 34.0% versus 23.6% for ipilimumab, with Keytruda reducing the risk of death by 29% (HR=0.71).
  • Median OS for Keytruda was more than double that of ipilimumab (32.7 months versus 15.9 months), highlighting the long-term efficacy of pembrolizumab.
  • Keytruda has shown sustained survival benefits of five years or more across multiple cancer types, marking its transformative impact on cancer treatment.

Daiichi Sankyo's DS-9606 Shows Early Promise in Advanced Solid Tumors Expressing CLDN6

  • DS-9606, a CLDN6-directed antibody-drug conjugate, demonstrates preliminary clinical activity in heavily pretreated patients with advanced solid tumors.
  • The Phase 1 trial of DS-9606 showed manageable safety profile with no dose-limiting toxicities observed across dose levels.
  • Early efficacy signals include confirmed objective responses in germ cell, gastric/esophageal, and non-small cell lung cancers.
  • Further evaluation is ongoing to determine the recommended dose for expansion and to assess DS-9606's potential across various CLDN6-expressing tumor types.

TAR-200 Shows High Complete Response Rate in BCG-Unresponsive NMIBC

  • TAR-200 monotherapy demonstrated an 84% complete response rate in patients with BCG-unresponsive, high-risk non-muscle-invasive bladder cancer (NMIBC) carcinoma in situ.
  • The SunRISe-1 phase 2b study evaluated TAR-200 alone or with cetrelimab, showing durable responses without reinduction in the TAR-200 monotherapy arm.
  • TAR-200 was well-tolerated, with most adverse events being grade 1 or 2, supporting its prioritized development as a monotherapy for high-risk NMIBC.
  • These results offer a potential bladder-sparing alternative for patients who are ineligible or unwilling to undergo radical cystectomy, addressing a critical unmet need.

TAR-200 Demonstrates High Complete Response in BCG-Unresponsive Bladder Cancer

  • TAR-200 monotherapy achieved an 83.5% complete response rate in patients with Bacillus Calmette-Guérin (BCG)-unresponsive, high-risk non-muscle-invasive bladder cancer (HR-NMIBC).
  • Durable complete responses were observed, with 82% of patients maintaining response after a median follow-up of 9 months, suggesting long-term efficacy.
  • The safety profile of TAR-200 was favorable, with low discontinuation rates due to treatment-related adverse events, supporting its potential as a monotherapy.
  • Cetrelimab monotherapy showed a 46.4% complete response rate, while the combination of TAR-200 and cetrelimab resulted in a 67.9% complete response rate.

LEAP-012 Trial: Lenvatinib, Pembrolizumab, and TACE Improve PFS in Intermediate-Stage HCC

  • The LEAP-012 trial demonstrated that combining lenvatinib and pembrolizumab with TACE significantly improves progression-free survival (PFS) in intermediate-stage hepatocellular carcinoma (HCC).
  • The combination therapy showed a median PFS of 14.6 months compared to 10 months with TACE alone, representing a 34% reduction in the risk of disease progression or death.
  • The objective response rate (ORR) was also higher in the combination arm (46.8%) compared to the placebo arm (33.3%), indicating enhanced clinical activity.
  • While treatment-related adverse events were more frequent in the combination arm, they were generally manageable, suggesting a favorable risk-benefit profile.
