Trial Summary

What is the purpose of this trial?

This phase I trial studies how well atezolizumab before and/or with standard of care chemoradiotherapy works in immune system activation in patients with stage IB2, II, IIIB, or IVA cervical cancer that has spread to the lymph nodes. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving atezolizumab before and/or with chemoradiotherapy may lower the chance of tumors growing or spreading.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on systemic immunosuppressive medications, you must stop them at least 2 weeks before starting the trial. Also, if you are taking a RANKL inhibitor, you need to discontinue it before treatment with atezolizumab.

What data supports the effectiveness of the treatment Atezolizumab + Chemoradiotherapy for Cervical Cancer?

Research shows that combining chemotherapy with radiotherapy, particularly using cisplatin, improves survival rates in cervical cancer compared to radiotherapy alone. Additionally, intensity-modulated radiotherapy (IMRT) can reduce side effects and improve treatment precision.12345

Is the combination of Atezolizumab and chemoradiotherapy safe for treating cervical cancer?

The combination of Atezolizumab with other treatments like bevacizumab has been studied for safety in advanced cervical cancer, and chemoradiotherapy with cisplatin is a standard treatment with known safety profiles. Intensity-modulated radiation therapy (IMRT) can reduce side effects like gastrointestinal issues, and cisplatin is generally well-tolerated when used with radiotherapy.12678

How is the treatment Atezolizumab + Chemoradiotherapy for Cervical Cancer different from other treatments?

This treatment combines Atezolizumab, an immunotherapy drug that helps the immune system fight cancer, with chemoradiotherapy, which is the standard treatment for cervical cancer. The addition of Atezolizumab is novel as it may enhance the effectiveness of the existing chemoradiotherapy regimen by boosting the body's immune response against the cancer.124910

Treatment Details

Interventions

  • Atezolizumab
  • Brachytherapy
  • Cisplatin
  • Radiation Therapy
Trial Overview The study tests the effectiveness of atezolizumab when given before and/or alongside standard chemoradiotherapy in activating the immune system against cervical cancer. Atezolizumab is a monoclonal antibody designed to help the body's immune system detect and fight tumor cells.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Arm B (atezolizumab, standard cisplatin and radiation therapy)Experimental Treatment4 Interventions
Patients receive atezolizumab IV over 30-60 minutes on days 0, 21, and 42 in the absence of disease progression or unacceptable toxicity. Patients also receive standard of care cisplatin chemotherapy, radiation therapy, and image guided brachytherapy as in Arm A.
Group II: Arm A (atezolizumab, standard cisplatin and radiation therapy)Experimental Treatment4 Interventions
Patients receive atezolizumab IV over 30-60 minutes on days -21, 0, and 21 in the absence of disease progression or unacceptable toxicity. Patients also receive standard of care cisplatin chemotherapy IV over 90 minutes on days 0, 7, 14, 21, 28, and 35. Beginning on day 0, patients also receive standard of care radiation therapy once daily (Monday-Friday) for a total of 25 fractions with image guided brachytherapy beginning in week 4, 5, or at the end of radiation therapy.

Findings from Research

Intensity-modulated radiotherapy (IMRT) for cervical cancer has been shown to reduce gastrointestinal toxicity while allowing for higher doses of radiation to be targeted at tumors, improving treatment safety.
Individualized, image-guided brachytherapy enhances the precision of high-dose radiation delivery, adapting to the tumor's specific shape and size, which may lead to better tumor control.
Radiotherapy of Cervical Cancer.Vordermark, D.[2017]
Chemotherapy combined with radiation therapy has significantly improved overall survival rates in patients with locally advanced cervical carcinoma, with weekly cisplatin (40 mg/m²) showing the best response compared to other combinations.
Despite the exploration of various other cytotoxic and biologic agents, no treatment has proven to be more effective than weekly cisplatin in conjunction with radiotherapy, which remains the standard therapy for this condition.
Novel chemotherapy approaches in chemoradiation protocols.González-Cortijo, L., Carballo, N., González-Martín, A., et al.[2008]
Cisplatin is the primary systemic anti-cancer agent used in conjunction with radiation for locally advanced cervical cancer, but its overall effectiveness is limited.
Recent phase 3 trials show that adding bevacizumab to chemotherapy regimens (cisplatin/paclitaxel or paclitaxel/topotecan) significantly improves overall survival for patients with metastatic or recurrent cervical cancer.
