About TACTI-004
TACTI-004 (Two ACTive Immunotherapies) is a randomised, double-blind, controlled Phase III study evaluating eftilagimod alfa (efti), a first-in-class MHC Class II agonist, in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy, KEYTRUDA (pembrolizumab), and chemotherapy as first line therapy for patients with advanced or metastatic non-small cell lung cancer with no EGFR, ALK or ROS1 genomic tumour aberrations. The global trial will enrol approximately 756 patients regardless of PD-L1 expression and with non-squamous or squamous tumours at over 150 clinical sites in over 25 countries. Patients will be randomised 1:1 to receive either efti in combination with pembrolizumab and chemotherapy in the treatment arm or pembrolizumab in combination with chemotherapy and placebo in the control arm. The study’s dual primary endpoints are progression-free survival and overall survival.

About Eftilagimod Alfa (Efti)
Efti is a novel immunotherapy that directly activates antigen-presenting cells or APCs (e.g. dendritic cells, monocytes) via the MHC Class II pathway to fight cancer. As an MHC Class II agonist, its activation of APCs engages the adaptive and innate immune system to initiate a broad anti-cancer immune response. This includes priming and activating cytotoxic T cells as well as generating important co-stimulatory signals & cytokines that further boost the immune system’s ability to combat cancer.

Efti is under evaluation for a variety of solid tumours including non-small cell lung cancer (NSCLC) in a pivotal Phase III trial called TACTI-004 (KEYNOTE-F91), as well as head and neck squamous cell carcinoma (HNSCC), soft tissue sarcoma, and breast cancer. Its favourable safety profile enables various combinations like with anti-PD-[L]1 immunotherapy, radiotherapy, and/or chemotherapy. Efti has received Fast Track designation in first line HNSCC and in first line NSCLC from the United States Food and Drug Administration (FDA).

In addition, Bicycle announced a collaboration with United Kingdom National Nuclear Laboratory (UKNNL), pursuant to which it plans to extract 228Th from the RepU obtained from NDA. The extracted 228Th will then be further processed into 224Ra and loaded into a bespoke 212Pb generator being developed exclusively for Bicycle by SpectronRx. 212Pb is a radioisotope and one of the more potent therapeutic payloads against cancer cells known as Targeted Alpha Therapy (TAT).

Collectively, this bespoke set of arrangements is designed to support the potential discovery, development, and commercial supply of a portfolio of Bicycle Radioconjugates (BRC) containing 212Pb.

"Cancer is a disease that affects millions worldwide, and tears too many families apart. Breakthroughs in medical science are giving more cancer patients and their loved ones hope, and this unique partnership could help take that work even further. Turning nuclear material into cutting-edge cancer treatments sounds like science fiction – but thanks to the brilliance of scientists, researchers and doctors, it could be a life-saving reality. Work like this shows exactly why we’re determined to support our life sciences innovators to make groundbreaking new treatments possible," said Liz Kendall, Secretary of State.

"These new collaborations are testaments to the potential of Bicycle to advance a differentiated and exciting isotope agnostic radiopharmaceuticals portfolio. We believe we now have the resources and infrastructure we need to create the world’s first end-to-end 212Pb radiopharmaceutical ecosystem from discovery through development to commercial supply. We believe the potential of BRCs and our ability to incorporate the appropriate isotopes for specific patient needs is unique and creates significant value-creating capabilities," said Mike Hannay, D.Sc., FRPharmS, chief product and supply chain officer of Bicycle Therapeutics. "We are incredibly grateful to the UK government for their recognition of Bicycle’s potential to develop BRCs with a 15-year access agreement for reprocessed uranium, and to our partners SpectronRx with whom we are developing a bespoke 212Pb generator. We look forward to advancing these dynamic collaborations and developing our pipeline of radiopharmaceuticals with the potential of improving lives for cancer patients around the globe."

"I am delighted with the progress we are making in establishing ourselves as a potential leader in radiopharmaceutical R&D. Today’s announcement builds on our previous announcements concerning our agreement with Eckert & Ziegler to supply a range of radioisotopes for the manufacture of BRC products as well as the formation of our Research and Innovation Advisory Board (RAB) comprising some of the worlds most esteemed experts in radiopharmaceuticals," said Bicycle Therapeutics CEO Kevin Lee, Ph.D. "As we continue to advance our emerging BRC pipeline, currently with novel targets EphA2 and MT1-MMP, we look forward to presenting initial EphA2 human imaging data in the first half of 2026 and initiating our own Bicycle study in 2026."
