The updated TACTI-002 data, with a cut-off date of August 15, 2023 and a median follow up of over 2 years (25.1 months), was presented by Dr. Enric Carcereny, Catalan Institute of Oncology (ICO), Badalona, Spain, during a Mini Oral session (#1312MO) at ESMO Congress 2023 on Saturday, October 21st. Key takeaways from the oral presentation detailing results from efti in combination with KEYTRUDA® for frontline treatment of advanced or metastatic NSCLC in the TACTI-002 Phase II trial1 include:
Table 1: Overall Survival of Efti + KEYTRUDA® versus standard-of-care IO, IO-IO, IO-chemo, and IO-IO-chemo therapies for first-line treatment of advanced non-small cell lung cancer patients with PD-L1 TPS ≥1%
Therapy | Median Overall Survival2 |
Efti + Pembrolizumab | 35.5 months |
Pembro + Doublet Chemo (NSQ)* | 23.3 months |
Pembro + Doublet Chemo (SQ)* | 18.9 months |
Ipilimumab + Nivolumab3 | 17.1 months |
Pembrolizumab monotherapy3 | 16.4 months |
Ipi + Nivo + 2 cycles Doublet Chemo | 15.8 months |
* NSQ=Non-squamous;SQ=Squamous
In NSCLC patients with >1% PD-L1 expression, a key area for efti’s future development where it has FDA Fast Track status, the ORR (48.3%), mPFS (11.2 months), mDOR (24.2 months), and mOS (35.5 months) compare overall favourably to historical results of anti-PD-1 monotherapy, as well as to historical results of approved anti-PD-1 + chemo-containing regimens. Collectively, the breadth of efficacy and safety data from the large number of metastatic NSCLC patients in the Phase II TACTI-002 trial offers compelling evidence of efti’s substantial impact in safely stimulating the patients’ immune response to fight cancer.
Dr. Enric Carcereny stated, “The strong efficacy data across all levels of PD-L1 expression in TACTI-002, especially in PD-L1 low (1-49%) and PD-L1 negative (<1%) patients, differentiates efti in combination with anti-PD-1 from other chemo-free immuno-oncology combinations in the frontline treatment of advanced or metastatic non-small cell lung cancer. Unlike other IO-IO combinations that only work in high PD-L1 expressing patients or IO-chemo combinations that rely on toxic chemotherapy to drive better efficacy, efti is clearly enabling deep, durable responses for patients regardless of PD-L1 expression with a favourable safety profile that’s in line with anti-PD-1 monotherapy.”
Marc Voigt, Immutep CEO stated, “We are extremely pleased to report these excellent overall survival results, the gold standard benchmark within oncology, in patients with metastatic non-small cell lung cancer, and believe these are among the strongest ever delivered in a sizable Phase II clinical trial like TACTI-002 evaluating a dual immuno-oncology approach. The strength of the data positions us well as we continue to plan and prepare for our Phase III trial that we expect to launch next year.”
Conference Call and Webcast DetailsImmutep will host a conference call and webcast to discuss the clinical data presented at ESMO 2023 and provide an overview on future clinical development plans for efti in 1st line non-small cell lung cancer. The event will feature CEO Marc Voigt, CSO Dr Frederic Triebel, CMO Dr Florian Vogl, and Christian Mueller, Senior Vice President Strategic Development. An open question & answer session with all presenters will conclude the event. A replay of the webcast will be available under the Events section of Immutep’s website.
Lung cancer is the second most common cancer. Non-small cell lung cancer accounts for approximately 80-85% of all lung cancers, impacting an estimated 1.87 million people annually, and is the highest cause of death among all cancers4-6.

About Eftilagimod Alpha (Efti)Efti is Immutep’s proprietary soluble LAG-3 protein and MHC Class II agonist that stimulates both innate and adaptive immunity for the treatment of cancer. As a first-in-class antigen presenting cell (APC) activator, efti binds to MHC (major histocompatibility complex) Class II molecules on APC leading to activation and proliferation of CD8+ cytotoxic T cells, CD4+ helper T cells, dendritic cells, NK cells, and monocytes. It also upregulates the expression of key biological molecules like IFN-ƴ and CXCL10 that further boost the immune system’s ability to fight cancer.
Efti is under evaluation for a variety of solid tumours including non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and metastatic breast cancer. Its favourable safety profile enables various combinations, including with anti-PD-[L]1 immunotherapy and/or chemotherapy. Efti has received Fast Track Designation in 1st line HNSCC and in 1st line NSCLC from the United States Food and Drug Administration (FDA).
