Innovative Cancer Therapy Shows Promise in Lung Cancer Trials

Groundbreaking Results in Lung Cancer Treatment

In an exciting development for cancer treatment, recent trials conducted under the supervision of Immutep Limited (ASX: IMM; NASDAQ: IMMP) have demonstrated impressive response rates in first-line non-small cell lung cancer (NSCLC). The combination of eftilagimod alpha (efti), the anti-PD-1 therapy KEYTRUDA® (pembrolizumab), and standard chemotherapy has reported a remarkable 60.8% response rate along with a 90.2% disease control rate in patients treated within the framework of the investigator-initiated INSIGHT-003 trial.

Understanding the Trial and Its Implications

The INSIGHT-003 trial showcases a novel combination aimed at improving outcomes for patients suffering from advanced or metastatic non-squamous NSCLC. Approximately 92% of the evaluable patients in this trial exhibited PD-L1 Tumor Proportion Scores (TPS) of less than 50%, highlighting a significant area of unmet need. More specifically, around 43% of these patients had PD-L1 TPS below 1%, indicating a critical demographic that often struggles to find effective treatment options.

This innovative combination therapy is particularly important considering the lack of response often faced by patients with lower PD-L1 expression levels, which can result in few available therapies. Data from the trial indicate a pronounced improvement over historical controls, further solidifying the safety and efficacy of this approach.

CEO's Insights on the Efficacy of Efti

Marc Voigt, CEO of Immutep, expressed great optimism regarding the outcomes of both the INSIGHT-003 and the pivotal TACTI-004 trials. He emphasized that the efficacy data derived from these studies, encompassing a diverse group of 165 patients with first-line NSCLC, builds the company's confidence in confirming efti as a new standard of care. He particularly noted the interim Overall Response Rate (ORR) results in patients with lower PD-L1 expression, where consistent and noteworthy improvements in response rates were observed across different trial settings.

Significant Improvements Across PD-L1 Levels

Detailed analysis of the evaluable patients reveals a striking augmentation in ORR across various PD-L1 expression levels when compared to previous historical data. For those exhibiting high PD-L1 expression (TPS > 50%), the ORR surged to 75%, up from 62.1% historically. Likewise, patients with low PD-L1 expression saw an ORR of 64% compared to 49.2%, while those with a negative PD-L1 expression reported a 54.5% response rate compared to just 32.3% historically.

Safety Profile and Next Steps in Research

Safety assessments continue to show a favorable profile for this triple combination therapy, indicating no significant new safety signals at this point. As Immutep prepares for future updates and presentations regarding the ongoing developments in the INSIGHT-003 trial, stakeholders are eagerly awaiting further results. These critical updates are expected to be delivered at an upcoming medical conference in the not-too-distant future.

About Eftilagimod Alpha

Efti, the centerpiece of Immutep's innovative strategy, is designed as a soluble LAG-3 protein and MHC Class II agonist. It plays a vital role in enhancing the body's immune response against cancer by activating antigen-presenting cells, which in turn stimulates important immune cells to fight against malignancies effectively. This first-in-class treatment shows promising potential for various solid tumors, including NSCLC and others, displaying a safety profile that allows it to be effectively combined with immunotherapies and chemotherapies.

About Immutep Limited

Immutep is setting itself apart as a leader in the biotechnology space, focusing on devising novel immunotherapeutic solutions for cancer treatment and autoimmune diseases. With a strong commitment to advancing therapies targeting LAG-3, the company strives to enhance patient outcomes significantly, while also emphasizing its responsibility to increase shareholder value.
