Sintilimab for Cancer of Unknown Primary
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called sintilimab for individuals with Cancer of Unknown Primary (CUP), where the cancer's origin remains unidentified. The trial aims to assess the effectiveness and safety of sintilimab for patients who did not respond well to previous chemotherapy. Participants should have CUP that cannot be surgically removed or treated with radiation and must have tried at least one standard treatment. For those whose cancer treatments have failed and whose cancer's primary site is unknown, this trial might be suitable. As a Phase 2 trial, the research focuses on evaluating the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have received certain treatments like systemic immunosuppressants or specific cancer therapies within 2 weeks before starting the trial.
Is there any evidence suggesting that sintilimab is likely to be safe for humans?
Research has shown that sintilimab, a type of cancer treatment, has been tested in various studies for different cancers, including cancer of unknown primary (CUP). In earlier trials, sintilimab helped shrink tumors in some CUP patients. The side effects resembled those of other treatments, allowing most patients to handle them well.
One study found that when combined with other drugs, sintilimab produced promising results and had manageable side effects for patients with advanced cancers. This suggests that sintilimab is generally well-tolerated, though side effects can occur, as with any cancer treatment.
Since this trial is in Phase 2, early testing has indicated that sintilimab is safe enough for more participants. However, participants should discuss any concerns with their healthcare provider.12345Why do researchers think this study treatment might be promising?
Sintilimab is unique because it targets the PD-1 pathway, which is a different approach compared to the traditional chemotherapy and radiation treatments typically used for cancer of unknown primary. Most standard treatments focus on attacking cancer cells directly, but sintilimab works by unleashing the immune system to recognize and fight cancer cells more effectively. This immunotherapy approach has the potential to offer a more personalized treatment option with potentially fewer side effects. Researchers are excited about sintilimab because it could provide a new avenue for patients who have limited options and improve outcomes by enhancing the body's natural immune response to cancer.
What evidence suggests that sintilimab might be an effective treatment for cancer of unknown primary?
Research has shown that sintilimab, a type of immune therapy, offers promising results for treating cancer of unknown primary (CUP). In one study, sintilimab helped shrink or slow tumor growth in some CUP patients. Another study found that patients treated with immune checkpoint inhibitors like sintilimab lived longer than those who did not, with an average survival time of 17.3 months. Additionally, sintilimab has been linked to a good response rate and longer periods without cancer progression. These findings suggest that sintilimab could effectively manage CUP.16789

Are You a Good Fit for This Trial?
This trial is for adults with Cancer of Unknown Primary (CUP) who've had no luck with at least one chemotherapy, can't have surgery or definitive treatments, and are expected to live more than 12 weeks. They need a measurable tumor and good organ function but can't join if they're pregnant, have serious infections or immune diseases, recent major surgeries or vaccines, certain blood clots or liver problems.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Sintilimab
Trial Overview
The trial tests Sintilimab's effectiveness and safety in treating CUP. Participants will receive Sintilimab intravenously every three weeks up to two years unless the disease worsens or side effects become too severe. Tumor response is monitored using RECIST criteria through imaging every nine weeks initially.

Experimental Treatment
The study drug is sintilimab. The first dose of study treatment should start on Day 1 of Cycle 1. For the rest of the treatment cycles, the study treatment can be administered 3 day before or 3 days after the scheduled day of administration. Treatment can be delayed for up to 1 week if the administration day is on a holiday or if the subject is otherwise unavailable.
