What You Need to Know Before You Apply

What is the purpose of this trial?

To evaluate progression of metastatic renal cell carcinoma from the initiation of PULSAR radiotherapy in combination with IMSA101 injectable onward.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the combination of radiotherapy and checkpoint inhibitors safe for treating kidney cancer?

Immune checkpoint inhibitors, which are part of the treatment, can cause immune-related side effects, but these are often linked to better outcomes in kidney cancer patients. The overall safety of these treatments has been studied, but specific safety data for the combination with radiotherapy is not detailed in the available research. ^{1 2 3 4 5}

How is the treatment with IMSA101 different from other kidney cancer treatments?

The treatment combines radiotherapy with a checkpoint inhibitor, which is unique because it uses the body's immune system to fight cancer cells while also targeting them with radiation. This combination may enhance the effectiveness of the immune response against kidney cancer, which is traditionally considered resistant to radiation alone. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment Radiotherapy + Checkpoint Inhibitor for Kidney Cancer?

Research shows that combining PD-1 inhibitors (a type of drug that helps the immune system fight cancer) with radiotherapy can be effective in treating advanced kidney cancer. Additionally, immune checkpoint inhibitors like nivolumab and ipilimumab have been successful in treating metastatic renal cell carcinoma, suggesting potential benefits for similar treatments. ^{4 6 8 11 12}

Are You a Good Fit for This Trial?

This trial is for individuals with metastatic renal cell carcinoma, a type of kidney cancer that has spread to other parts of the body. Specific eligibility criteria are not provided, so it's important to contact the study organizers for detailed requirements.

Inclusion Criteria

My cancer has spread to 3 or fewer places.

My organ and bone marrow functions are within normal ranges.

All IMDC risk categories are allowed

Exclusion Criteria

My cancer has not spread to the center of my chest.

What Are the Treatments Tested in This Trial?

Interventions

• IMSA101
• Radiotherapy

Trial Overview The trial is testing the effectiveness of PULSAR radiotherapy when combined with an injectable treatment called IMSA101 in slowing down or stopping the progression of metastatic kidney cancer.

How Is the Trial Designed?

Group I: SAbR with Intratumoral STING agonist IMSA101 and IO with Anti-PD1 Experimental Treatment 1 Intervention

Only one arm will be maintained in this phase II study with all patients undergoing the following treatment: SOC treatment: Nivolumab 480 mg monthly PULSAR: 36 Gy in 3 fractions, Q4weeks IMSA101: five intra-tumoral injections of one of the progressive lesions at 1200 mcg (C1D1, C1D8, C1D15, C2D1, C3D1)

Published Research Related to This Trial

The combination of ipilimumab and nivolumab has been approved as the first dual checkpoint inhibitor therapy for treatment-naïve patients with intermediate to poor risk metastatic renal cell carcinoma (mRCC), marking a significant advancement in immunotherapy for this cancer.

This review discusses the trials that led to the approval of this combination therapy and highlights ongoing research, indicating a strong focus on optimizing treatment for various patient populations and addressing remaining clinical questions.

Ipilimumab and Nivolumab as First-Line Treatment of Patients with Renal Cell Carcinoma: The Evidence to Date. Sheng, IY., Ornstein, MC.[2020]

Lenvatinib plus pembrolizumab had the highest rates of severe treatment-related adverse events (grade ≥3 TRAEs) and treatment discontinuation among the combination therapies for advanced renal cell carcinoma.

Nivolumab plus ipilimumab had the lowest rates of severe TRAEs but was linked to more endocrine-related adverse events, highlighting the need to balance efficacy with safety in treatment choices.

Adverse events of systemic immune-based combination therapies in the first-line treatment of patients with metastatic renal cell carcinoma: systematic review and network meta-analysis. Quhal, F., Mori, K., Remzi, M., et al.[2023]

A 56-year-old woman with recurrent renal cell carcinoma showed significant reduction in multiple metastases after receiving conventional palliative radiotherapy following 22 cycles of nivolumab, an immune checkpoint inhibitor.

This case suggests that combining radiotherapy with immune checkpoint inhibitors may produce systemic effects, potentially leading to an abscopal effect, where localized treatment impacts distant metastases.
