What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on patients with pancreatic cancer, specifically a type known as pancreatic ductal cancer. The study aims to explore the effects of adding an additional treatment to the standard care that is usually given to prevent blood clots, which are known as thrombosis. The additional treatment being tested is called antiplatelet therapy, which involves using medications that help prevent blood cells called platelets from clumping together and forming clots.

In this study, two medications are being used. The first is Plavix, which contains the active ingredient clopidogrel and is taken as a film-coated tablet. The second is Fragmin, which contains dalteparin sodium and is given as an injection. The purpose of the study is to see if adding antiplatelet therapy to the usual treatment can more effectively prevent blood clots in patients with pancreatic cancer.

Participants in the study will receive either the standard treatment alone or the standard treatment plus the antiplatelet therapy. The study will last for up to 12 months, during which time the safety and effectiveness of the treatments will be monitored. The goal is to determine if the combination of treatments can reduce the risk of blood clots without causing significant side effects, such as major bleeding.

The research process

The trial runs in 4 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the trial

    Upon joining the trial, participants will be informed about the study's purpose, which is to investigate the effectiveness and safety of adding antiplatelet therapy to standard treatment to prevent blood clots in patients with pancreatic cancer.

    Participants must be over 18 years old and have been recently diagnosed with locally advanced, metastatic, or recurrent pancreatic ductal adenocarcinoma.

  2. Step 2

    Medication administration

    Participants will receive two types of medications: Plavix 75 mg film-coated tablets and Fragmin 5,000 IE solution for injection.

    Plavix is taken orally, which means it is swallowed as a tablet. The dosage is 75 mg, and it is taken once daily.

    Fragmin is administered through a subcutaneous injection, which means it is injected under the skin. The dosage is 5,000 international units (IE), and it is given once daily.

  3. Step 3

    Monitoring and follow-up

    Participants will be regularly monitored for any signs of blood clots or major bleeding, as these are the primary focus of the study.

    Regular follow-up appointments will be scheduled to assess the participant's health and the effectiveness of the treatment.

  4. Step 4

    Completion of the trial

    The trial is expected to continue until September 16, 2034. Participants will be informed about the end of their involvement in the study and any necessary follow-up care.

    The results of the trial will contribute to understanding the benefits and risks of adding antiplatelet therapy to standard treatment for preventing blood clots in pancreatic cancer patients.

Who can join the trial?

4 criteria

  • Participants must be over 18 years old.
  • Participants must have been newly diagnosed with pancreatic ductal adenocarcinoma, which is a type of pancreatic cancer. This diagnosis should preferably be within the last month.
  • The cancer can be locally advanced (spread to nearby areas), metastatic (spread to other parts of the body), or recurrent (returned after treatment).
  • There must be a planned treatment for the pancreatic ductal cancer.

Who cannot join the trial?

3 criteria

  • Patients who do not have pancreatic ductal cancer cannot participate.
  • Patients who are not within the specified age range cannot participate. The study is open to adults and older adults.
  • Patients who are part of a vulnerable population cannot participate. This means people who might need special protection or care.

Investigated drugs

  • Antiplatelet therapy

    is a type of treatment that helps prevent blood cells called platelets from sticking together and forming clots. In this trial, it is being added to the usual treatment to see if it can better prevent blood clots in patients with pancreatic cancer. Blood clots can be dangerous because they can block blood flow in the body, so this therapy aims to reduce that risk.

  • Standard thromboprophylaxis

    is the regular treatment given to patients to prevent blood clots. It usually involves medications that thin the blood, making it less likely for clots to form. In this trial, it serves as the base treatment to which the antiplatelet therapy is added, to see if the combination is more effective in preventing clots in patients with pancreatic cancer.

What is already known about the treatment

Antiplatelet therapy – This medication is taken orally and works by preventing blood cells called platelets from clumping together, which helps reduce the risk of blood clots. In the context of pancreatic ductal cancer, it is being studied to see if it can help prevent thrombosis, a condition where blood clots form in blood vessels. The medication is currently being evaluated in clinical trials to determine its effectiveness and safety when added to standard treatments for preventing blood clots in these patients. Antiplatelet therapy is classified as a type of blood thinner and is commonly used to prevent heart attacks and strokes by keeping blood flowing smoothly.

Investigated diseases

Pancreatic ductal cancer – Pancreatic ductal cancer is a type of cancer that begins in the ducts of the pancreas, which are responsible for transporting digestive enzymes. It typically starts when cells in the pancreatic ducts undergo mutations and begin to grow uncontrollably, forming a tumor. As the disease progresses, the tumor can invade nearby tissues and organs, potentially spreading to other parts of the body. The growth of the tumor can obstruct the bile duct, leading to jaundice, or block the pancreatic duct, causing digestive issues. Over time, the cancer may metastasize, affecting distant organs such as the liver or lungs. The progression of the disease can lead to various complications, impacting the patient's overall health and quality of life.
