Trastuzumab in Combination With Serplulimab and Chemotherapy for the Treatment of HER2-overexpressing Unresectable Locally Advanced or Metastatic Biliary Tract Cancer or Urothelial Carcinoma After Failure of Standard Therapy

his single-center phase II clinical study enrolls patients with unresectable locally advanced or metastatic HER2-overexpressing biliary tract cancer or urothelial carcinoma who have failed standard treatment. Participants receive trastuzumab in combination with serplulimab and chemotherapy. The study aims to evaluate the efficacy and safety of this regimen in this patient population. The primary endpoint is objective response rate (ORR). Secondary endpoints include overall survival (OS), progression-free survival (PFS), and safety.

Efficacy and Safety of GemCis Plus Trastuzumab Plus Pembrolizumab in Previously Untreated HER2-positive Biliary Tract Cancer

This is a multicenter, single arm, prospective, open-label phase II trial investigating the clinical activity triplet regimen consisting of a combination of chemotherapy (gemcitabine/cisplatin) + trastuzumab + pembrolizumab as first-line treatment for cholangiocarcinoma and gallbladder cancer patients. Patients suffering from previously untreated HER2 (human epidermal growth factor receptor 2) positive, unresectable cholangiocarcinoma and gallbladder cancer will be included in the study and are scheduled to receive triplet regimen consisting of a combination of pembrolizumab, trastuzumab and gemcitabine/cisplatin (GemCis).

Artificial Intelligence-assisted HER2 Expression Assessment in Urothelial Carcinoma Based on Imaging-pathology Omics

This study aims to build upon previous research by using artificial intelligence methods to fuse multimodal data from imaging and pathology to construct a predictive model for HER2 expression in urothelial carcinoma. The model's performance will be validated and optimized using a multicenter cohort study, ultimately achieving accurate and rapid prediction of HER2 expression. This will guide precise decision-making for further HER2-targeted therapy and improve patient prognosis. Big data analysis and deep learning will also assist physicians in more accurately diagnosing the disease and developing personalized treatment plans. The research findings will promote the integration and development of artificial intelligence technology with the healthcare industry in the application of multimodal data from clinical, imaging, and pathology perspectives.

Efficacy and Safety of Distamab Vedotin Combined With Carboplatin for Advanced Ovarian Cancer in the First Line Treatment

Ovarian cancer exhibits the highest mortality rate among gynecological malignancies. Currently, the combination of paclitaxel and carboplatin remains the standard first-line chemotherapy regimen for neoadjuvant or postoperative treatment of ovarian cancer. However, conventional paclitaxel, due to the addition of polyoxyethylated castor oil solubilizer, may induce various adverse reactions beyond chemotherapeutic toxicity, such as hypersensitivity, toxic renal injury, neurotoxicity, and cardiovascular toxicity. Therefore, exploring optimized treatment regimens to provide patients with new therapeutic options is imperative. HER2 is a protein encoded by the ERBB2 gene that regulates cell survival, proliferation, and differentiation. HER2 gene amplification and/or protein overexpression are observed in 18%-35% of mucinous ovarian cancers. A meta-analysis involving over 5,000 ovarian cancer cases revealed that HER2 overexpression correlates with reduced overall survival (OS) and progression-free survival (PFS), suggesting its potential as a biomarker for poor prognosis. The emergence of novel antibody-drug conjugates (ADCs) has brought new hope for anti-HER2 therapy in ovarian cancer, such as Disitamab Vedotin (RC48). Preliminary results from the PRaG3.0 trial presented at the 2023 ASCO Annual Meeting showed an ORR of 66.7% in six HER2-expressing gynecological cancer patients treated with RC48 combined with radiotherapy and immune checkpoint inhibitors (ICIs). Updated data from the RC48-C018 study demonstrated an ORR of 36.4%, median duration of response (mDoR) of 5.52 months, mPFS of 4.37 months, and 12-month OS rate of 66% in 22 cervical cancer patients. RC48 exhibited promising efficacy and manageable safety in recurrent/metastatic HER2-expressing (IHC 1+/2+/3+) cervical cancer. Regarding safety, the GOG-158 study reported pronounced hematologic toxicity with carboplatin-paclitaxel in advanced ovarian cancer: grade 3/4 leukopenia (\>50%), thrombocytopenia (\>30%), and neutropenia (\>80%). Conversely, a retrospective study of RC48 combined with platinum ± bevacizumab in HER2-mutated NSCLC patients showed an ORR of 71.4% with no dose reductions or discontinuations due to adverse events. Thus, RC48-platinum combinations may offer a lower-toxicity alternative. Thus the investigators designed this trial to evaluate the efficacy and safety of RC48 combined with carboplatin in HER2-expressing advanced ovarian cancer.

RADIomics to Predict HER2 Status And T-DXd Efficacy in Metastatic Breast Cancer: the RADIOSPHER2 Study

RADIOSPHER2 study is a monocentric, retrospective, observational study aiming at identifying a radiomics signature able to predict HER2 expression (0 vs low vs overexpression) and trastuzumab deruxtecan efficacy in metastatic breast cancer patients. The study also encompasses translational analyses and inter-modal correlations in order to provide novel insights about HER2 spatial and temporal heterogeneity, at the macroscopic and microscopic levels.

A Composite Assay for HER2-positive Early-stage Breast Cancer Management

The goal of this observational study is to assess the prognostic value of a genomic classifier (S18) and its refined version (S\*) in women with early-stage HER2-positive breast cancer. The study aims to determine whether these tools can predict event-free (EFS) and disease-free survival (DFS) in patients treated with neoadjuvant and/or adjuvant trastuzumab-based therapies.

RC48 Combined With Tislelizumab for Bladder Sparing Treatment in NMIBC With BCG Treatment Failure and HER2 Expression

This is a prospective, open, single-center clinical study of anti-HER2-ADC combined with PD-1 monoclonal antibody for bladder sparing treatment in non-muscular invasive bladder cancer (NMIBC) patients with HER2-expressing. The study was conducted in accordance with the Good Clinical Practice (GCP). Approximately 20 subjects will be enrolled to evaluate the efficacy and safety of RC48 (RC48 2.0 mg/kg intravenously administered every two weeks) combined with Tislelizumab (Tislelizumab 200 mg intravenously administered every three weeks). Subjects undergo Transurethral resection of bladder tumor (TURBT), imaging diagnosis and pre-treatment biological samples of blood, urine and biopsy tissue. The study will include high-risk NMIBC patients who express HER2, fail after BCG treatment, but refuse to undergo cystectomy or do not meet the requirements for cystectomy. Subjects will receive RC48 and Tislelizumab for two years. BI-DFS were evaluated by cystoscopy, histopathologic examination, laboratory examination, and imaging examination after treatment, and tumor efficacy was evaluated when clinical studies reached the number of subjects specified in the protocol for efficacy evaluation.
