Official title
Phase II RAINSPOT: a Multicentric Open Label Trial of Zolbetuximab-Paclitaxel-Ramucirumab in Second Line Setting for CLDN18.2 Positive Gastro-esophageal Adenocarcinoma
Overview
This study examines whether adding the drug Zolbetuximab to an existing treatment (Paclitaxel and Ramucirumab) can improve patients' survival. The goal is to see if this combination works better for patients whose tumours contain a specific protein (CLDN18.2). The results will be compared to past patient data from those who only received the standard treatment. Zolbetuximab (Vyloy) is a cancer medicine that is used to treat adults with gastric or gastro-esophageal junction adenocarcinoma (a type of cancer of the stomach or the transition between the stomach and esophagus). Zolbetuximab will be administered via an intravenous infusion in combination with Paclitaxel and Ramucirumab (Cyramza) (two other cancer drugs that are the standard treatment for this condition). Treatment will take place at regular intervals in the hospital. In addition to treatment,patients will undergo a tumour biopsy. While the biopsy procedure may cause some discomfort or pain, it will only be performed if medically justifiable. Patients participation in the study will continue as long as they receive treatment and the disease does not worsen. The overall duration of the study, for all patients, will span several years.
Interventions
- Drug zolbetuximab
The investigational product, Zolbetuximab, is a sterile lyophilized powder preparation with the chimeric monoclonal antibody Zolbetuximab as the active pharmaceutical ingredient. - Other Retrospective cohort, no intervention
No intervention
Primary outcome measures
- OS (overall survival) [Time frame: From enrollment to the last FU visit of the patient (2 years)]
Secondary outcome measures (2)
- PFS (progression free survival) [Time frame: From enrollment till last FU visit of patient (2 years). Data will be reported at the final study report (max 3 years from study start).]]
- Safety analysis [Time frame: Up to 90 days after last Zolbetuximab dose for each individual patient]
