What is IMFINZI?

How was IMFINZI studied?

A clinical trial compared 2 groups of adults with locally advanced or metastatic bile duct cancer (cholangiocarcinoma) or gallbladder cancer:

341 people received IMFINZI + chemotherapy*
344 peoplereceived placebo (no medicine) +
chemotherapy*

IMFINZI + chemotherapy* helped people live longer compared to those taking chemotherapy* alone:

Median Overall Survival

12.8 months

taking IMFINZI + chemotherapy*

11.5 months

taking placebo + chemotherapy*

The study measured median overall survival, which is the length of time from the start of treatment to the time that half of the patients were still living.

IMFINZI with chemotherapy* lowered the risk of death by 20% compared to chemotherapy* alone.

†The study measured median overall survival, which is the length of time from the start of treatment to the time that half of the patients were still living.

 Data cutoff was August 11, 2021.

IMFINZI + chemotherapy* is the first and only immunotherapy-based treatment option with 4-year survival data in advanced BTCs

In a follow-up analysis at 4 years:

0%

of adults who received IMFINZI + chemotherapy* were still living

0%

of adults who received chemotherapy* alone were still living

A follow-up analysis, which is called a post-hoc analysis, was done with a group of people from this original clinical trial. This analysis was conducted approximately 4 years after the last patient started treatment in this study and measured overall survival at 4 years. Given the nature of this disease, fewer patients were evaluated in this analysis. Based on the limitations of the analysis, results are descriptive, and your experience may differ.

Data cutoff was February 28, 2025.
IMFINZI with Chemotherapy Lowered the Risk of Cancer Growth or Spread by 25%

IMFINZI + chemotherapy* lowered the chance of the cancer growing or spreading compared to chemotherapy* alone.


In the original clinical trial analysis, IMFINZI with chemotherapy* lowered the risk of cancer growing or spreading by 25% compared to chemotherapy* alone.

Within the trial, half of the people taking IMFINZI with chemotherapy* lived without their tumors growing or spreading for 7 months, compared to 6 months for people taking chemotherapy* alone.

Data cutoff was August 11, 2021.

Important Safety Information

What is the most important information I should know about IMFINZI® (durvalumab)?

IMFINZI is a medicine that may treat certain cancers by working with your immune system. IMFINZI can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.

What is IMFINZI?

IMFINZI is a prescription medicine used to treat adults with a type of cancer called biliary tract cancer (BTC), including cancer of the bile ducts (cholangiocarcinoma) and gallbladder cancer. IMFINZI may be used in combination with chemotherapy medicines gemcitabine and cisplatin when your BTC has spread to nearby tissues (locally advanced), or has spread to other parts of the body (metastatic).

It is not known if IMFINZI is safe and effective in children.

Call or see your healthcare provider right away if you develop any new or worsening signs or symptoms, including:

  • BTC Lung Icon

    Lung problems: cough, shortness of breath, and chest pain

  • BTC Intestinal Icon

    Intestinal problems: diarrhea (loose stools) or more frequent bowel movements than usual; stools that are black, tarry, sticky, or have blood or mucus; and severe stomach-area (abdomen) pain or tenderness

  • BTC GVHD Signs

    Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with IMFINZI. Your healthcare provider will monitor you for these complications

Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with IMFINZI.
