Long-term follow-up GDFATHER-01 trial: GDF-15 neutralization combined with nivolumab can enable deep, long-term remission in heavily pretreated, anti-PD1/-L1 relapsed/refractory non-squamous non-small cell lung cancer (NSCLC), urothelial cancer (UC) and hepatocellular cancer (HCC) (ESMO 2025) - P1/2 | "Conclusions In 77 heavily pre-treated, by strict criteria anti-PD-1/-L1 relapsed/refractory nsq NSCLC, UC and HCC pts, V+N treatment induced very durable and deep long-term response, with 61.5% (8/13) of responders achieving confirmed CR or CMR. GDF-15 neutralization by V may overcome ICI resistance and enable long-term immunologic tumor control in metastatic nsq NSCLC, UC and HCC."

N/V combination warrants further investigation in larger neoadjuvant trials with a tumor response-guided bladder preservation approach."

Neutralizing GDF-15 can overcome anti-PD-1 and anti-PD-L1 resistance in solid tumours. (PubMed, Nature) - P1/2 | "In a first-in-human phase 1-2a study (GDFATHER-1/2a trial, NCT04725474 ), patients with advanced cancers refractory to anti-PD-1 or anti-PD-L1 therapy (termed generally as anti-PD-1/PD-L1 refractoriness) were treated with the neutralizing anti-GDF-15 antibody visugromab (CTL-002) in combination with the anti-PD-1 antibody nivolumab. Increased levels of tumour infiltration, proliferation, interferon-γ-related signalling and granzyme B expression by cytotoxic T cells were observed in response to treatment. Neutralizing GDF-15 holds promise in overcoming resistance to immune checkpoint inhibition in cancer."

Definitive results for NSCLC and Bladder cancer cohorts in the phase 2a trial of visugromab (CTL-002) in advanced/metastatic anti-PD/PD-L1 relapsed/refractory solid tumors (GDFATHER-trial) (ESMO-IO 2023) - P1/2 | "Here we report definitive results for NSCLC and bladder cancer cohorts of the phase 1/2a trial of the GDF-15 neutralizing antibody visugromab (CTL-002) in combination with nivolumab for treatment of patients that were relapsed/refractory to anti-PD1/-PD-L1 therapy and had exhausted standard-of-care. Confirmed partial and complete responses with significant durability up to and beyond 1 year were observed. Biomarker analyses suggest that visugromab can reinvigorate, enhance and deepen response to checkpoint inhibitors mainly in PD-L1+ patients even after documented prior progression on a seamlessly administered checkpoint inhibitor, being relapsed/refractory to it."

Characterization of Growth Differentiation Factor 15 (GDF-15) as a therapeutic target in urothelial carcinoma (DGU 2025) - "A clinical study demonstrated that treatment with an anti-GDF-15 antibody (visugromab) in combination with nivolumab can lead to sustained remissions in otherwise ICI-resistant patients with mUC... The therapeutic target GDF-15 is highly expressed, particularly in molecularly luminal UC. Higher expression is associated with an immunosuppressive TME. Investigation of the association between GDF-15 expression and response to ICI therapies is ongoing."
