Clinical Trials in Nonmelanoma Skin Cancer

Clinical trials for nonmelanoma skin cancers (NMSCs), including Cutaneous Squamous Cell Carcinoma (CSCC) and Basal Cell Carcinoma (BCC), are crucial for advancing the understanding and treatment of these conditions. Here are some of the key areas where clinical trials are currently focused:

1. Immune Checkpoint Inhibitors
Cemiplimab (Libtayo) and Pembrolizumab (Keytruda): Ongoing trials are exploring the use of these PD-1 inhibitors in various stages of CSCC and BCC, including in combination with other therapies.
Combination Therapies: Trials are investigating the efficacy of combining immune checkpoint inhibitors with other treatments like chemotherapy, radiation, or other immune-modulating agents.

2. Hedgehog Pathway Inhibitors
Vismodegib (Erivedge) and Sonidegib (Odomzo): New trials are evaluating these drugs in combination with other therapies, as well as in patients with advanced or recurrent BCC who have not responded to initial treatments.
Novel Hedgehog Inhibitors: Researchers are testing new agents that target the Hedgehog signaling pathway, potentially offering more effective or better-tolerated options for BCC treatment.

3. Targeted Therapies
Molecular Targeting Agents: Clinical trials are focusing on drugs that target specific mutations or pathways involved in NMSCs, such as inhibitors of the EGFR pathway in advanced CSCC.
Next-Generation Sequencing: Trials are exploring the use of personalized medicine approaches, using genetic profiling to identify and target specific mutations in NMSCs.

4. Combination Therapy Trials
Immunotherapy and Radiation: Combining immune checkpoint inhibitors with radiation therapy is being tested to see if it can enhance the anti-tumor immune response in NMSCs.
Chemotherapy and Immunotherapy: Trials are investigating the potential benefits of combining systemic chemotherapy with immunotherapy for advanced or metastatic NMSCs.

5. Neoadjuvant and Adjuvant Therapies
Neoadjuvant (Pre-Surgery) Trials: Studies are looking at the use of systemic therapies before surgery to shrink tumors and improve surgical outcomes in CSCC and BCC.
Adjuvant (Post-Surgery) Trials: These trials focus on the use of therapies after surgery to reduce the risk of recurrence in high-risk NMSC patients.

6. Novel Drug Delivery Systems
Topical and Injectable Agents: Trials are evaluating new formulations of existing drugs or novel agents delivered directly to the tumor site, aiming to minimize systemic side effects while maximizing local efficacy.

7. Vaccine and Cellular Therapies
Cancer Vaccines: Investigational vaccines are being tested to stimulate the immune system to recognize and attack NMSC cells.

CAR-T Cell Therapy: Early-phase trials are exploring the use of CAR-T cell therapy, which involves genetically modifying a patient's T cells to better target and destroy cancer cells.

8. Supportive Care Trials
Quality of Life and Symptom Management: These trials focus on improving the quality of life for patients with NMSCs by addressing side effects, managing symptoms, and providing psychological support during and after treatment.

9. Prevention and Early Detection Trials
Chemoprevention: Some trials are evaluating the use of systemic or topical agents to prevent the development of NMSCs in high-risk populations.
Screening and Detection: Trials are also underway to test new methods for early detection of NMSCs, including advanced imaging techniques and biomarker development.

10. Pediatric Trials
NMSCs in Children: Although rare, clinical trials are investigating treatment approaches for pediatric patients with NMSCs, focusing on safety and efficacy in this population.

Patients interested in participating in clinical trials should discuss the options with their healthcare provider, who can help identify suitable trials based on the patient’s specific condition, treatment history, and location. Additionally, clinical trials can often be found through registries like ClinicalTrials.gov or through specialized cancer centers like the Lurie Cancer Center.
