SystImmune to Present Updated Izalontamab Brengitecan Data for HER2-Negative Breast Cancer at ESMO Breast 2025

  • SystImmune will present updated Phase 1 data on izalontamab brengitecan (iza-bren), a novel EGFRxHER3 bispecific antibody-drug conjugate, at ESMO Breast Cancer 2025 in Munich, Germany.
  • The data shows encouraging efficacy across all HER2 levels in HER2-negative breast cancer patients, including HER2 0 patients, building on previously reported results at SABCS 2024.
  • Iza-bren, jointly developed by SystImmune and Bristol Myers Squibb, demonstrates strong clinical efficacy with a manageable safety profile, potentially addressing significant unmet needs in breast cancer treatment.

Dana-Farber Cancer Institute Launches Phase II Trials Testing Immunotherapy in Meningioma and Melanoma

  • Dana-Farber Cancer Institute is conducting two Phase II clinical trials evaluating immunotherapy approaches for different cancer types, including nivolumab for progressive meningiomas and dostarlimab for resectable melanoma.
  • The meningioma trial (15-490) tests nivolumab alone or in combination with radiation therapy in patients with WHO grade I-III progressive or recurrent meningiomas, including those who have failed prior radiation therapy.
  • The melanoma trial (21-201) evaluates neoadjuvant dostarlimab in patients with cutaneous or unknown primary melanoma at various AJCC stages, requiring measurable disease and adequate organ function.
  • Both studies have specific inclusion criteria regarding prior treatments, with the meningioma trial allowing unlimited prior therapies while the melanoma trial excludes patients with prior PD-1/PD-L1 inhibitor treatment.

Nivolumab Shows Promise in Refractory Biliary Tract Cancer with 22% Response Rate in Phase II Trial

  • A phase II study of nivolumab in 54 patients with refractory biliary tract cancer demonstrated a 22% partial response rate and 60% disease control rate with median overall survival of 14.22 months.
  • The anti-PD-1 antibody was well tolerated with only 20.4% of patients experiencing grade III/IV treatment-related adverse events, and no discontinuations due to toxicity.
  • A separate randomized phase 2 trial combining stereotactic body radiotherapy with nivolumab/ipilimumab showed 31% clinical benefit rate but limited overall response rate of 11.9%.
  • These results support further investigation of immunotherapy approaches in biliary tract cancer, a disease with limited treatment options and poor prognosis.

CytomX Therapeutics Initiates Combination Therapy Arm in Phase 1 Melanoma Trial

  • CytomX Therapeutics has dosed the first patient in a combination arm studying CX-801 with Keytruda (pembrolizumab) for patients with metastatic melanoma.
  • The Phase 1 trial aims to evaluate safety, tolerability, and preliminary efficacy of this novel combination approach targeting advanced melanoma patients.
  • This study represents a significant step in exploring how CX-801's mechanism may potentially enhance the effectiveness of established immunotherapy treatments.

Yuhan's Lung Cancer Drug Leclaza Secures European Approval in Combination Therapy

  • Yuhan Corporation's third-generation EGFR-TKI lazertinib (Leclaza) has received European Commission approval in combination with J&J's Rybrevant for first-line treatment of EGFR-mutated non-small cell lung cancer.
  • The Phase 3 MARIPOSA study demonstrated the combination therapy reduced disease progression risk by 30% compared to osimertinib, with median progression-free survival of 23.7 months versus 16.6 months.
  • This milestone marks the first Korean anticancer drug approved in both the U.S. and Europe, triggering a $30 million payment to Yuhan as part of their $1.255 billion licensing deal with Johnson & Johnson.

CEL-SCI Secures $5 Million in Public Offering to Advance Multikine Cancer Immunotherapy

  • CEL-SCI Corporation has priced a $5 million public offering of 16.13 million shares at $0.31 per share to fund continued development of Multikine, a first-line cancer immunotherapy.
  • The company has received FDA clearance to conduct a confirmatory Registration Study for Multikine in 212 patients with locally advanced head and neck cancer who have specific characteristics.
  • Multikine is designed to boost the immune system's ability to target tumors while it's still intact, potentially improving survival outcomes for cancer patients.

FDA Approves Tevimbra-Chemotherapy Combination for First-Line Treatment of Advanced Esophageal Squamous Cell Carcinoma

  • The FDA has approved BeiGene's Tevimbra (tislelizumab-jsgr) in combination with platinum-containing chemotherapy for first-line treatment of adults with unresectable or metastatic esophageal squamous cell carcinoma whose tumors express PD-L1.
  • In the pivotal RATIONALE-306 trial, patients treated with Tevimbra plus chemotherapy demonstrated a median overall survival of 16.8 months compared to 9.6 months with chemotherapy alone, representing a 34% reduction in risk of death.
  • This marks BeiGene's third FDA approval in less than a year, following previous approvals for Tevimbra in second-line ESCC and first-line gastric/gastroesophageal junction cancers, highlighting the company's expanding oncology portfolio.

Endevica Bio Advances TCMCB07 to Phase 2 Trial for Preventing Chemotherapy-Induced Weight Loss

  • Endevica Bio has received FDA authorization to begin a Phase 2 clinical trial of TCMCB07 (B07), a peptide designed to prevent weight loss in stage 4 metastatic colorectal cancer patients undergoing chemotherapy.
  • The trial will enroll 100 patients who will receive B07 before and during chemotherapy, targeting cachexia - a life-threatening wasting syndrome affecting millions of cancer patients worldwide.
  • TCMCB07, a melanocortin-3/4 antagonist peptide, has shown promising results in Phase 1 trials and preclinical studies, demonstrating its ability to preserve lean muscle mass and improve appetite in cancer treatment settings.

PeproMene Bio Secures $11 Million Investment to Advance BAFF-R CAR T-Cell Therapy for Follicular Lymphoma

  • PeproMene Bio has received an $11 million investment from the Institute for Follicular Lymphoma Innovation to develop PMB-CT01, a novel BAFF-R CAR T-cell therapy for relapsed/refractory follicular lymphoma.
  • Early clinical results show promising efficacy with a 100% complete response rate in six non-Hodgkin lymphoma patients and minimal side effects, including in patients who relapsed after CD19 CAR T-cell therapy.
  • PMB-CT01 targets the BAFF-R receptor, which is crucial for B-cell survival, potentially making it difficult for tumor cells to escape therapy through antigen loss, a common limitation of current CD19-targeted therapies.

Federal Jury Awards Lindis Biotech $50 Million in Patent Infringement Case Against Amgen's Blincyto

  • A Delaware federal jury found Amgen's Blincyto cancer drug willfully infringes two Lindis Biotech patents for leukemia treatment administration methods.
