Calluna Pharma AS (Calluna), a clinical stage biotechnology company pioneering first-in-class antibodies to treat inflammatory and fibrotic diseases, today announced the completion of Phase 1 clinical study for CAL101, Calluna’s lead product candidate. The study demonstrated a favorable safety, pharmacokinetic (PK) and immunogenicity profile for the mAb. CAL101 is a first-in-class mAb that targets S100A4, a damage-associated molecular pattern (DAMP) protein implicated in serious and life-threatening diseases, such as idiopathic pulmonary fibrosis and systemic sclerosis.

Preclinical studies have demonstrated the ability of CAL101 to prevent and treat fibrosis and modify the disease-specific activation of fibroblasts – the key effector cells driving progression of fibrosis. We are encouraged by the findings from the Phase 1 study. These results are an important step forward in the development of our lead asset, CAL101, particularly for fibrotic and fibro-inflammatory diseases where there remains a critical need for innovative therapeutic options.



We are excited as we now move into the next phase of clinical development.” Jonas Hallén M.D.
