What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if IP-001, an experimental treatment, is safe and effective for individuals with certain solid tumors. It targets those with soft tissue sarcoma, non-small cell lung cancer, or colorectal cancer. Participants will first undergo radiofrequency ablation, a procedure that uses heat to destroy cancer cells, followed by an injection of IP-001 directly into the tumor. Individuals with stage 3 or 4 cancer who have not responded to other treatments may be suitable for this trial, particularly if their tumors are smaller and accessible for treatment. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot participate if you are on systemic corticosteroids, other immunosuppressive therapy, or anti-coagulation therapies that can't be stopped 24 hours before treatment. Also, you must not have received chemotherapy, radiotherapy, immunotherapy, or other investigational agents within 21 days prior to treatment.

Is there any evidence suggesting that IP-001 is likely to be safe for humans?

Research has shown that IP-001, when injected into tumors after thermal ablation, was tested in earlier studies with 38 patients. These studies involved individuals with various cancers, including soft tissue sarcoma, non-small cell lung cancer, and colorectal cancer. The results indicated that IP-001 was generally well-tolerated.

Some patients experienced side effects, but most were mild to moderate. Common issues included minor pain and swelling at the injection site. These findings suggest that using IP-001 with thermal ablation is relatively safe. However, as this trial is in an early stage, more research is needed to fully understand its safety and effectiveness. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about IP-001 because it offers a novel approach to treating solid cancers like Soft Tissue Sarcoma, Non-Small Cell Lung Cancer, and Colorectal Cancer. Unlike traditional treatments that often involve systemic chemotherapy or targeted therapies, IP-001 is injected directly into the tumor, which may enhance its effectiveness and reduce side effects. This unique delivery method is combined with radiofrequency ablation (RFA), which could potentially increase the tumor's susceptibility to the treatment. By directly targeting the tumor, IP-001 aims to improve treatment outcomes and provide a new hope for patients with these challenging cancers.

What evidence suggests that IP-001 might be an effective treatment for solid cancers?

This trial will evaluate the effectiveness of IP-001 for treating solid tumors, including soft tissue sarcoma, non-small cell lung cancer, and colorectal cancer. Participants will receive radiofrequency ablation (RFA) followed by an intratumoral injection of IP-001. Research has shown that IP-001 may enhance the body's immune response to cancer cells when injected directly into the tumor. In earlier studies, patients who received IP-001 after thermal ablation of their tumors showed positive initial responses. Early results suggest it could be particularly beneficial for individuals who haven't responded to standard treatments like chemotherapy. While further research is needed, these early findings offer promise for those considering joining this trial. ^{1 3 6 7 8}

Published Research Related to This Trial

Intraperitoneal (IP) chemotherapy for epithelial ovarian cancer showed a high completion rate (80.5% completed at least six cycles) despite a significant incidence of severe toxicity (Grade 3 or 4 in 73.2% of patients).

The study suggests that while IP chemotherapy can be effective, especially after optimal debulking surgery, careful monitoring for toxicity is essential, particularly in patients who have undergone neoadjuvant chemotherapy.

Direct intratumoral injection of immunotherapeutic agents can lead to local immune activation while reducing systemic toxicity, making it a safer alternative to intravenous administration.

Intratumoral delivery has shown improved efficacy and the potential for abscopal effects, especially when combined with immune checkpoint inhibitors, highlighting its promise in cancer treatment.

Delivery routes matter: Safety and efficacy of intratumoral immunotherapy. De Lombaerde, E., De Wever, O., De Geest, BG.[2021]

Intratumoral immunotherapy is a promising approach that enhances the effectiveness of cancer treatments by directly delivering immune-activating therapies into tumors, which helps overcome the immunosuppressive environment that often limits systemic therapies.

Effective delivery of these therapies into the tumor is crucial for their success, and the review discusses various minimally invasive delivery devices that can improve the administration of intratumoral therapies.

The Contemporary Landscape and Future Directions of Intratumoral Immunotherapy. Brito-Orama, S., Sheth, RA.[2023]

Intratumoral delivery of immunotherapy is a promising strategy for treating early-stage solid tumors, as it minimizes severe side effects associated with systemic delivery while enhancing local tumor-specific immunity.

Over 20 ongoing neoadjuvant clinical trials are exploring various intratumoral immune stimulatory agents, indicating a strong interest in optimizing this approach for effective cancer treatment.

Intratumoural therapies, which involve directly injecting treatments into tumors, show promise in transforming 'cold' tumor microenvironments into 'hot' ones that can better respond to immune checkpoint inhibitors, potentially improving patient outcomes.

Melanoma has been the primary focus for these therapies due to its immunogenic nature, but advancements are enabling the application of intratumoural treatments to other cancer types, supported by improved injection techniques.

The combination of cisplatin and irinotecan as induction chemotherapy followed by chemoradiotherapy did not show sufficient anti-tumor activity, with an overall response rate of only 45%, which was below the threshold for efficacy.

The treatment was associated with significant toxicity, including neutropenia, diarrhea, and fatigue, leading to the conclusion that the regimen was poorly tolerated and did not provide a clinical benefit.

Immune checkpoint inhibitors targeting PD-1, PD-L1, and CTLA-4 have improved survival rates in cancer patients by enhancing the immune response against tumors, but only a small percentage of patients experience long-term benefits and these treatments can cause severe autoimmune side effects.

Intratumoral immunotherapy, which involves injecting immunostimulatory agents directly into tumors, can achieve high local drug concentrations while minimizing systemic toxicity, potentially allowing for more effective and safer cancer treatments.

The study involved 60 patients with advanced ovarian cancer receiving a regimen of intravenous docetaxel and intraperitoneal cisplatin and paclitaxel, showing a tolerability profile with manageable toxicities, primarily neutropenia (47%) and gastrointestinal issues (28%).

The treatment resulted in a high complete response rate of 88%, with a median progression-free survival of 25.5 months and overall survival of 56.8 months, indicating promising efficacy for this chemotherapy approach.
