What side effects are associated with this type of intervention?

Common treatments for colorectal cancer, such as fluoropyrimidine-based chemotherapy, oxaliplatin-based regimens, and cetuximab, have several known side effects. Fluoropyrimidine-based chemotherapy can cause gastrointestinal symptoms like nausea, vomiting, diarrhea, and mucositis, as well as myelosuppression leading to anemia, leukopenia, and thrombocytopenia. Oxaliplatin-based regimens often result in peripheral neuropathy, which can be acute or chronic, along with similar gastrointestinal and hematologic toxicities. Cetuximab, an epidermal growth factor receptor inhibitor, can cause skin reactions, including acneiform rash, as well as infusion-related reactions, hypomagnesemia, and, less commonly, sepsis. These side effects can significantly impact the patient's quality of life and may require dose adjustments or discontinuation of therapy.

What prior FDA approvals exist?

Several FDA-approved drugs have demonstrated anti-tumor properties in the treatment of colorectal cancer. These include chemotherapeutic agents such as fluorouracil, leucovorin, oxaliplatin, and irinotecan, which are often used in combination regimens like FOLFOX and FOLFIRI. Targeted therapies such as bevacizumab, an anti-VEGF monoclonal antibody, and cetuximab, an anti-EGFR monoclonal antibody, have also been approved for use in metastatic colorectal cancer. These treatments aim to inhibit tumor growth and progression, similar to the investigational drug SM08502 being studied for its anti-tumor efficacy in advanced solid tumors.

What other types of research exist?

Promising novel alternatives to SM08502 for colorectal cancer patients include NK012, a polymeric micelle formulation of SN-38, which has shown efficacy in patients with unresectable metastatic colorectal cancer. Additionally, targeting the VEGF pathway with agents like bevacizumab has demonstrated activity in advanced colorectal cancer. These alternatives offer potential anti-tumor benefits and should be considered in consultation with a healthcare provider.

Summary

This trial is testing a new drug called SM08502, taken by mouth, in adults with advanced solid tumors. The goal is to see if it helps other cancer treatments work better. The drug is taken for several days with short breaks in between.

Who is the study for?

Adults with advanced solid tumors like colorectal, lung, or prostate cancer can join this trial. They should be in good health otherwise, have a life expectancy over 3 months, and not have severe side effects from past treatments. Participants need to be able to take pills and agree to use birth control.

What is being tested?

The trial is testing SM08502 taken orally with standard hormonal therapy or chemotherapy for treating advanced cancers. It's an open-label study where everyone knows what treatment they're getting. The dose may change as the study goes on.

What are the potential side effects?

Possible side effects include those typical of chemotherapy such as nausea, fatigue, hair loss; hormonal therapy might cause hot flashes or mood swings; and SM08502 could potentially cause digestive issues or affect how other drugs work.

Trial Design

Experimental Treatment

Group I: NSCLC (Non-Small Cell Lung Cancer) - SM08502 + DocetaxelExperimental Treatment2 Interventions

Part 1 (dose escalation cohorts) will evaluate SM08502 in subjects with advanced NSCLC. Subjects will receive increasing doses of SM08502 with fixed doses of docetaxel to determine the MTD and recommended Part 2 dose and schedule. Escalation will follow a 3+3+3 design within each cohort. Part 2 will further evaluate the recommended dose and schedule of SM0850 in subjects with advanced NSCLC. Approximately 20 subjects will be enrolled.

Group II: CRPC (Castration Resistant Prostate Cancer) - SM08502 + Abiraterone/PrednisoneExperimental Treatment3 Interventions

Part 1 (dose escalation cohorts) will evaluate SM08502 in subjects with advanced CRPC. Subjects will receive increasing doses of SM08502 with fixed doses of Abiraterone/Prednisone to determine the MTD and recommended Part 2 dose and schedule. Escalation will follow a 3+3+3 design within each cohort. Part 2 will further evaluate the recommended dose and schedule of SM08502 in subjects with advanced CRPC. Approximately 20 subjects will be enrolled.

Group III: CRC (Colorectal Cancer) - SM08502 + FOLFIRI/PanitumumabExperimental Treatment3 Interventions

Part 1 (dose escalation cohorts) will evaluate SM08502 in subjects with advanced CRC. Subjects will receive increasing doses of SM08502 with fixed doses of FOLFIRI plus panitumumab ( RAS wild type tumors) or with fixed doses of FOLFIRI (RAS mutant tumors) Escalation will follow a 3+3+3 design within each cohort. Part 2 will further evaluate the recommended dose and schedule of SM08502. Subjects that have RAS wild type tumors will receive FOLFIRI and panitumumab with SM08502 (n=15). Subjects that have RAS mutant tumors will receive FOLFIRI with SM08502 (n=15).

Other Research

Common treatments for colorectal cancer include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy, such as fluoropyrimidine-based regimens, works by interfering with DNA synthesis and cell division, leading to cancer cell death. Targeted therapies, like cetuximab and bevacizumab, inhibit specific molecules involved in tumor growth and angiogenesis, respectively. Immunotherapy, including checkpoint inhibitors, enhances the immune system's ability to recognize and destroy cancer cells. These mechanisms are crucial for colorectal cancer patients as they directly target the cancer cells' ability to grow and spread, improving treatment efficacy and patient outcomes. The trial of SM08502, which explores its anti-tumor properties in combination with chemotherapy or hormonal therapy, aims to enhance these effects by potentially offering a novel mechanism to inhibit tumor progression.
