Kazia Enrols First Patient to EVT801 Phase I Clinical Trial
Kazia Therapeutics Limited (KZIA) has commenced patient enrollment for a Phase I clinical trial of EVT801, an investigational cancer therapy. Licensed from Evotec SE in April 2021, EVT801 targets VEGFR3 to inhibit lymphangiogenesis, showing promising preclinical results. The trial aims to assess safety, tolerability, and pharmacokinetics while exploring preliminary efficacy signals through biomarker analyses. The study will recruit up to 60 patients at the IUCT-Oncopole in Toulouse, France, focusing on renal cell carcinoma and soft-tissue sarcoma. Kazia anticipates further updates as the trial progresses.
- Kazia has initiated a Phase I clinical trial for EVT801, a promising cancer therapy.
- EVT801 has demonstrated compelling preclinical results and broad tolerability in animal studies.
- The trial will utilize advanced biomarker analyses to gather valuable data on the drug's efficacy.
- No significant negative aspects were reported in the PR.
SYDNEY, Nov. 4, 2021 /PRNewswire/ -- Kazia Therapeutics Limited (NASDAQ: KZIA; ASX: KZA), an oncology-focused drug development company, is pleased to announce that it has commenced enrolment to a phase I clinical trial of EVT801, an investigational cancer therapy that Kazia licensed from Evotec SE in April 2021.
Key Points
- EVT801 is a small molecule inhibitor of VEGFR3, and acts by inhibiting lymphangiogenesis, the formation of new lymphatic vessels around the tumour. It has shown compelling evidence of activity in a wide range of preclinical cancer models and appears broadly well-tolerated in animal toxicology studies.
- Kazia licensed EVT801 from Evotec SE, an international drug discovery alliance and development partnership company, in April 2021.
- The phase I study will focus primarily on understanding the safety, tolerability, and pharmacokinetics of EVT801 across a range of doses. It is also designed to explore preliminary signals of clinical efficacy, and to investigate the biological activity of the drug via a rich suite of sophisticated biomarker analyses.
- The lead clinical site in the study is L'Institut Universitaire du Cancer de Toulouse Oncopole (IUCT-Oncopole) in Toulouse, France. The lead investigator is Dr Carlos Gomez-Roca, a medical oncologist with a strong background in drug development and early phase clinical trials.
- The phase I study is expected to recruit a maximum of 60 patients, with the actual number dependent on the emergent safety profile of the drug. Timelines to completion will depend on the number of dose levels tested, and Kazia expects to provide further guidance on this as the study progresses.
Dr Carlos Gomez-Roca commented, "We are pleased to now be enrolling patients to this phase I study of EVT801. Despite great progress in the treatment of cancer over recent years, there remains a substantial need for new therapeutic options in a wide range of tumours. EVT801 has shown promising preclinical data, and we very much hope that it may now prove beneficial to our patients."
Kazia CEO, Dr James Garner, added, "in the six months since we licensed EVT801, the Kazia and Evotec teams have been working assiduously to execute a first-in-human study of this very promising drug candidate. It has been a privilege to work with the team at the IUCT-Oncopole site in Toulouse, which is one of the leading cancer centres in France, and we hope to add an additional centre in the new year. We are delighted that the study is now open to recruitment. All of us in Kazia firmly believe that EVT801 has enormous potential as a novel cancer therapy, and we look forward to working closely with the investigators to explore that potential."
Dr Cord Dohrmann, Chief Scientific Officer of Evotec SE, said, "We are very excited to see EVT801 proceed to the clinic. The Phase I clinical trial will be conducted by Evotec, under the sponsorship of Kazia, at the renowned IUCT-Oncopole in Toulouse. Evotec will support the management of the Phase I clinical trial with analyses and biomarker development, which we anticipate will yield important data for the validation of the approach and to further contribute to the development of robust patient stratification strategies for the further clinical evaluation of EVT801."
Phase I Study Design
The phase I study of EVT801 is designed in two stages. The first stage is a multiple ascending dose (MAD) study, which is designed to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) for EVT801. Patients in the study will receive EVT801 at low doses, and this will be progressively escalated in subsequent cohorts as the safety profile of the drug is determined.
The second stage of the study will recruit twelve patients, of whom six will have been diagnosed with renal cell carcinoma and six with soft-tissue sarcoma. All twelve patients will receive EVT801 at the RP2D determined in the first stage. These patients will participate in intensive analyses to better understand the biochemical activity of the drug.
In addition to conventional measures of safety, efficacy, and pharmacokinetics, the phase I study will employ cutting edge biomarker technologies to provide early insights into the activity of EVT801. A rich program of tissue and blood biomarker analyses has been developed by Evotec scientists, in collaboration with the team at Oncopole. It is expected that these analyses will help to better understand the effects of the drug in human subjects and may also help to identify the most responsive patients and provide early predictors of clinical efficacy.
Kazia is also collaborating with Radiomics, an imaging analysis organisation based in Belgium, to apply sophisticated AI-based analyses to the CT and MRI scans collected during the study. Proprietary machine-learning algorithms developed by Radiomics can provide exceptionally detailed insights into the behaviour of the tumour while on treatment, and this information may help to predict and understand clinical response.
Clinical Sites
The lead site in the study is the Institut Universitaire du Cancer de Toulouse Oncopole (IUCT-Oncopole) in Toulouse, France. IUCT-Oncopole combines several leading clinical cancer treatment facilities with a world-class research infrastructure, on an integrated campus that brings together public and private stakeholders, including industry participants. The centre treats more than 10,000 new patients each year, and more than one in eight patients are enrolled in clinical studies.
The lead investigator for the study is Dr Carlos Gomez-Roca, medical oncologist and Chair of the Early Phase Unit at IUCT-Oncopole, Dr Gomez-Roca's clinical research is focused on development of targeted therapies and immuno-oncology drugs. He is a member of ESMO, ASCO, FITC and AACR, and has contributed to more than 60 peer-reviewed publications, including as first or second author, in journals such as the Journal of Clinical Oncology and Annals of Oncology.
