TURKU – FINLAND, 30 September 2019 Faron Pharmaceuticals Oy (AIM: FARN), the clinical stage biopharmaceutical company, today announces details from a poster discussion presentation held at the European Society of Medical Oncology (ESMO) 2019 Congress to showcase recent data from its ongoing MATINS study.

The phase I/II MATINS clinical trial is investigating the safety and efficacy of Clevegen, Faron’s wholly-owned novel precision cancer immunotherapy targeting Clever-1 positive tumour associated macrophages (TAM), in selected metastatic or inoperable solid tumours. During the session Dr Petri Bono, principal investigator of the MATINS trial, presented data showing Clevegen’s potential early efficacy and good tolerability. The discussion highlighted:

  • Good tolerability across all dosing levels with no dose limiting toxicity (DLT) observed. Maximally tolerated dose (MTD) has not been reached yet.
  • Promising clinical anti-tumour activity, evidenced by the trial’s first long-lasting partial responder – a heavily pre-treated metastatic colorectal cancer (CRC) patient, whose tumour had been classified as microsatellite instability (MSI)-low and tumour mutation burden (TMB), and who had previously been treated with six different anti-cancer drugs, which had all failed. MSI-low colorectal patients represent around 90% of all colorectal cancers and over one million annual cases globally.
  • Th1 immune activation was observed in all subjects measured following treatment with Clevegen, confirming earlier ex vivo results with human cells (Palani et al., 2016). The patients also increased circulating CD8+ T cells and CD8+/CD4+ ratio, decreased regulatory T-cells (T-regs) or had a substantial increase in mobile natural killer (NK) cells in the blood, all signs of this desired immune activation.
  • Clevegen’s potential to overcome the immunosuppressive environment in difficult-to-treat PD-1/PD-L1- resistant immunologically non-inflamed (cold) tumours, by converting them into inflamed (hot) tumours.
  • The ongoing development path investigating Clevegen as a monotherapy in CRC MSI-low patients and other advanced solid tumours (liver, pancreas, ovarian and melanoma), including targeting patients with hormone receptor-positive breast cancer, gastric cancer and uveal melanomas. The potential of Clevegen to bring a synergistic benefit to existing immunotherapies also warrants further investigation through future combination studies.

Commenting on the presented data, Dr. Petri Bono, principal investigator of the MATINS study, said: “We are very encouraged by the progress of this trial. The emerging tolerability profile and early signs of clinical benefit from this novel anti Clever-1 antibody are promising, particularly as the patients enrolled in the MATINS trial had already received several lines of treatment and exhausted all available options for further therapy. Early indications of its potential to convert cold tumours to hot are an important signal for the next wave of immunotherapies in development and we look forward to generating further data as the trial continues.”

The poster discussion was held at ESMO 2019, Barcelona, on 28 September 2019. The full abstract and poster are available online at the ESMO Congress website: https://www.esmo.org

Title: Immune activation with a novel immune switch anti-macrophage antibody (anti-Clever-1 mAb; FP-1305) in phase I/II first-in-human MATINS trial in patients with advanced solid tumours

Presenter: Dr. Petri Bono, MATINS trial principal investigator

About the MATINS study

The MATINS study is the first-in-human open label Phase I/II clinical trial with an adaptive design to investigate the safety and efficacy of Clevegen in selected metastatic or inoperable solid tumours. The selected tumours under investigation are cutaneous melanoma, hepatobiliary/hepatocellular, pancreatic, ovarian and colorectal cancer, all known to host a significant number of Clever-1 positive tumour associated macrophages (TAM). All together these five target groups consist of approximately 2 million annual cases worldwide. Cancer patients with high Clever-1 expression are identified with a simple blood myeloid cell staining with Clevegen (“liquid biopsy”).

Part I of the trial deals with tolerability, safety and dose escalation to optimize dosing. As the trial is an open label study, the Company expects to report findings as the dosing progresses. The cohort expansion during part two will focus on identification of patients who show an increased number of Clever-1 positive circulating monocytes and the safety and efficacy of the treatment. The Company has already announced that colorectal cancer (CRC) has been selected as the first expansion cohort in Part II. During Part III, the main focus will be on assessing the efficacy of Clevegen on study subjects who show an increased number of Clever-1 positive circulating monocytes, making the treatment precisely targeted and maximizing the chances of success for efficacy. The treatment, if successful, may ultimately be used as a standalone therapy or in combination with other immunotherapies like PD-1 inhibitors.

About Faron Pharmaceuticals Ltd

Faron (AIM:FARN) is a clinical stage biopharmaceutical company developing novel treatments for medical conditions with significant unmet needs. The Company currently has a pipeline based on the endothelial receptors involved in regulation of immune response, in oncology and organ damage. Clevegen, its precision immunotherapy, is a novel anti-Clever-1 antibody with the ability to switch immune suppression to immune activation in various conditions, with potential across oncology, infectious disease and vaccine development. Currently in phase I/II clinical development as a novel macrophage checkpoint immunotherapy for patients with untreatable solid tumours, Clevegen has potential as a single-agent therapy or in combination with other immune checkpoint molecules. Traumakine, the Company’s pipeline candidate to prevent vascular leakage and organ failures, has completed a phase III clinical trial in Acute Respiratory Distress Syndrome (ARDS). Plans for its future development are being finalised to avoid interfering steroid use together with Traumakine. Faron is based in Turku, Finland. Further information is available at www.faron.com
