Immune cells attacking cancer cells, illustrating targeted therapy.

Cutaneous squamous cell carcinoma (SCC) is a common skin cancer that, in its advanced stages, can be challenging to treat. While surgery is effective for most cases, a small percentage of tumors become metastatic or locally advanced, requiring systemic therapy. Recent research has focused on harnessing the power of immunotherapy to combat these advanced SCC cases. One promising approach involves targeting the programmed death-1 (PD-1) protein.

A study highlighted the efficacy of cemiplimab, a human monoclonal antibody that targets PD-1, in patients with advanced SCC. The results showed that cemiplimab elicited a durable response in a significant number of patients. Specifically, approximately 50% of patients with advanced or metastatic cutaneous SCC experienced a positive response to the treatment. This is particularly encouraging, as these patients often have limited treatment options due to the lack of efficacious approved systemic therapies.

  • What is PD-1? PD-1 is a protein on immune cells that helps keep them from attacking other cells in the body. In cancer, PD-1 can prevent immune cells from killing cancer cells.
  • How does cemiplimab work? Cemiplimab blocks the PD-1 protein, allowing immune cells to recognize and attack cancer cells.
  • What were the results of the study? Approximately 50% of patients with advanced SCC responded positively to cemiplimab treatment.

The report links molecular profiling, targeted drugs, and immune checkpoint inhibitors with individualized treatment. A 2024 case report states that, in malignant pleural mesothelioma, the immune environment and response markers such as CPS can have greater influence on first-line immunotherapy decisions than tumor histological type. Cancer Research UK also shares patient stories about people treated with immunotherapies and how research has made a difference to them.

Cemiplimab responses alongside a pembrolizumab benchmark

  • 28 of 59 (47%) patientsIn the metastatic-disease cohort, 28 of 59 patients responded to cemiplimab, an observed response share of 47%.[1]

How other reports frame PD-1 treatment in advanced skin cancer

A separate pembrolizumab trial reported a 38.5% objective response rate, a 5.1% complete response rate, and a median response duration of 12.5 months among patients with no prior systemic therapy. The cemiplimab report cited alongside it gave a 46.1% objective response rate, an estimated 87.8% response duration at 12 months, and a 16.1% complete response rate; the source notes that longer follow-up may partly account for the difference.[2]

A guideline places anti-PD-1 agents as first-line systemic treatment for metastatic or locally advanced cutaneous squamous cell carcinoma when curative surgery or radiotherapy is not an option. This describes a defined clinical setting, rather than every case of the disease.[3]

The sources also describe an evidence gap in predicting response: validated predictive biomarkers have not been established, and studies use varying definitions of PD-L1 positivity. This makes it difficult to interpret biomarker status consistently across reports.[4] [5]

What remains uncertain about response and treatment comparisons

  • How well do response rates from separate trials compare when patient histories and follow-up differ? The pembrolizumab reports include a previously treated population and a group with no prior systemic therapy, while the sources caution that trial designs differ.[2]
  • How do response durability and safety compare across treatments in direct testing? The cited comparison says no clinical trials directly compare cemiplimab with the other therapies and notes differences in study design.[6]

Terms used in the treatment reports

Checkpoint inhibitor
A drug that blocks checkpoint proteins from binding partner proteins, preventing an off signal to T cells.[7]

Everything You Need To Know

1

What exactly is PD-1 and why is it important in the context of cancer treatment?

PD-1, or programmed death-1, is a protein found on immune cells. Its primary function is to regulate the immune system by preventing immune cells from attacking other cells in the body. In the context of cancer, PD-1 can be exploited by cancer cells to evade immune detection and destruction, allowing the cancer to proliferate unchecked. Inhibiting PD-1, therefore, unleashes the immune system to target and destroy cancer cells effectively. The significance of PD-1 lies in its role as a crucial immune checkpoint, making it a prime target for cancer immunotherapy.
