Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure

Description of intervention(s) / exposure
Treatment: Drugs - zolbetuximab
Treatment: Drugs - nab-paclitaxel
Treatment: Drugs - gemcitabine

Experimental: zolbetuximab +nab-paclitaxel + gemcitabine - Participants will be treated with zolbetuximab in combination with nab-paclitaxel and gemcitabine for the phase 1 portion of the study to establish the recommended dose of zolbetuximab for the phase 2 portion. In the phase 2 portion, the participants will be treated with zolbetuximab at dose determined by the phase 1 portion of the study in combination with nab-paclitaxel and gemcitabine. Participants will be treated on continuous cycles until they no longer derive clinical benefit in the judgment of the treating physician, have unacceptable toxicity, undergo hematopoietic stem cell transplantation (HSCT), or meet one of the discontinuation criteria; whichever occurs first.

Active comparator: nab-paclitaxel + gemcitabine - Participants will be treated with nab-paclitaxel and gemcitabine. Participants will be treated on continuous cycles until they no longer derive clinical benefit in the judgment of the treating physician, have unacceptable toxicity, undergo hematopoietic stem cell transplantation (HSCT), or meet one of the discontinuation criteria; whichever occurs first.

Summary
Brief summary
Zolbetuximab is being studied as a treatment for people with pancreatic cancer. Most people with pancreatic cancer have a protein called Claudin 18.2 (CLDN18.2) in their tumor. Zolbetuximab is thought to work by attaching to CLDN 18.2 in their tumor. This switches on the body's immune system to attack the tumor. Zolbetuximab is a potential treatment for people with pancreatic cancer.

There is an unmet medical need to treat people with pancreatic cancer. This study will help find the dose of zolbetuximab to be used with chemotherapy and provide more information on this treatment in adults with metastatic pancreatic cancer. The study is currently ongoing globally. People in this study will be treated with either zolbetuximab and chemotherapy or chemotherapy by itself.

The study's main aims are to find a suitable dose of zolbetuximab to be used with chemotherapy in the second part of this study, to check if zolbetuximab and chemotherapy compared to chemotherapy by itself can improve the survival of people with pancreatic cancer, and to check the safety of zolbetuximab when given with chemotherapy and how well people cope with medical problems during the study.

Adults with metastatic pancreatic cancer can take part. Their cancer is metastatic, has the CLDN18.2 marker in a tumor sample and has not previously been treated with chemotherapy. Metastatic means the cancer has spread to other parts of the body. People cannot take part are if they have recently had radiotherapy and have not recovered, need to take medicines to suppress their immune system, have history of nervous system metastases from their pancreatic cancer, or they have other active cancers that need treatment. People who have a specific heart condition or infections also cannot take part.

This study will be in 2 parts. Part 1 is called the Safety Lead-in Phase. Groups of people will receive 1 of 2 different doses of zolbetuximab: a lower dose or a higher dose, both together with chemotherapy. A medical expert panel will check the results and decide the dose to use in Part 2.

Part 2 is called the Randomization Phase. People will be put in 1 of 2 groups by chance and will be given different treatments either zolbetuximab and chemotherapy or chemotherapy by itself. The chance of receiving zolbetuximab and chemotherapy is twice as high as receiving chemotherapy by itself. In both parts of the study, zolbetuximab and chemotherapy or chemotherapy by itself will be given through a vein. This is called an infusion. Each treatment cycle is 4 weeks (28 days) long and people will have either 2 infusions of zolbetuximab and 3 infusions of chemotherapy or 3 infusions of chemotherapy by itself during each treatment cycle. People will visit the clinic on certain days during their treatment. The study doctors will check for any medical problems from zolbetuximab. Also, people in the study will have a health check including blood tests. On some visits they will also have scans to check for any changes in their cancer. Tumor samples will be taken before treatment if a previous sample is not available. People will have the option of giving a tumor sample after treatment has finished. People will visit the clinic after they stop treatment. They will be asked about any medical problems and will have a health check including blood tests. The number of visits and checks done at each visit will depend on the health of each person and whether they completed their treatment or not.
