Background

Breast cancer is the most common cancer and is one of the leading causes of cancer-related deaths worldwide.

Data published between 2016 to 2018 suggests that close to 56,000 new cases of breast cancer are diagnosed in the UK, mostly affecting females, and with 86% presenting with early disease.

Most breast cancers have proteins (receptors). 皇冠体育appse include oestrogen receptor-positive (ER+), where breast cancers have receptors for the hormone oestrogen, and HER2-negative, where the protein is absent 鈥� human epidermal growth factor 2.

Hormones, particularly oestrogen, can attach to these receptors and encourage the cells to grow. A pathologist can identify the receptors during biopsy or surgery, helping to determine treatment.

Recent research has led to the development of new candidate drugs known as SERDS (selective oestrogen receptor degraders). 皇冠体育appse drugs are designed to attach to and disrupt these oestrogen receptors, preventing the growth of cancer.

A new SERD molecular entity, camizestrant, is under clinical development by biopharmaceutical company AstraZeneca and is currently in a Phase III study. 皇冠体育app drug candidate is administered orally in the form of a film-coated tablet and acts by targeting oestrogen receptors.

This Phase III open-label study in early breast cancer enrols 5,500 patients worldwide. It aims to assess if camizestrant improves survival outcomes compared to standard adjuvant endocrine-based therapy for patients who are ER-positive and HER2-negative.聽聽

Good practice clinical trials application

皇冠体育app MHRA鈥檚 agile regulatory framework for clinical trials supports innovation in the life sciences sector by assessing and approving safe, effective, and efficient trials that benefit patients in the UK and around the world.聽聽

AstraZeneca submitted a compliant application for the clinical study to the MHRA in September 2023. 皇冠体育appir cover letter addressed the recommended points of reference for the MHRA assessors, including signposting and highlighting certain areas that have changed, and cross referencing to other studies and guidance.

皇冠体育app company focused on the quality, effectiveness, and safety profile of camizestrant and the other investigational medicinal products relevant to the patient population. 皇冠体育app protocol and documents appropriately reflected the risks and mitigation measures, making the task as efficient as possible for the MHRA鈥檚 assessors.聽

An agile and responsive regulator聽聽

皇冠体育app MHRA鈥檚 expert assessors took a risk-proportionate, targeted approach to reviewing the camizestrant clinical trial application. This medicine had already been used in people with cancer, so evidence was available to support the application.

Whilst acknowledging that this study design was simple, the protocol was well written and clearly presented. 皇冠体育app agency was adequately assured of the pharmaceutical quality, risk mitigation measures and safety reporting to support a favourable risk/benefit balance for the trial.聽聽

Decision

皇冠体育app MHRA issued a decision in 25 calendar days. 皇冠体育app final outcome (acceptance) for the study was in 32 days. No grounds for non-acceptance were issued from any MHRA assessors, and the responses from the Research Ethics Committee and Health Research Authority were received promptly.聽聽

Since 1st September 2023, the MHRA has assessed all initial applications within the statutory timeframe of 30 days.

鈥淭his continually improving performance in regulatory timescales, along with a holistic national health service, an active academic research community and an ethnically diverse population, makes the UK a globally competitive location for clinical research,鈥� comments Andrea Manfrin, the MHRA鈥檚 Deputy Director, Clinical Investigations and Trials.

鈥淥ur experts are dedicated and pragmatic in their approach to assessing trials. We are committed to providing predictable and reliable timescales for Clinical Trial Authorisation applications, so that sponsors can plan with confidence their studies in the UK.鈥�

皇冠体育app MHRA receives between 950 and 1,000 clinical trial authorisation (CTA) applications for investigational medicinal products (IMPs) per year, with more than half requiring additional information to be submitted before they are considered approvable.

To assist applicants, the MHRA has published online guidance that identifies common issues with the validation and assessment of clinical trial applications and how to avoid them throughout the process, helping to ensure that clinical trials are assessed efficiently.

Applicants can also ask for scientific advice from the MHRA at any stage of the development of their medicine.

Advice on specific or regulatory aspects of a clinical trial can also be obtained via the agency鈥檚 Clinical Trials Helpline at [email protected].
