At Cancer Research UK, we exist to beat cancer.

Cancer Research UK have an opportunity for a meticulous and diligent individual, with experience and knowledge of clinical trials, to join us as a Medical Writing Associate within our Centre for Drug Development (CDD).

The Cancer Research UK CDD is the world”s only charity-funded drug development facility. Our pioneering research is driven purely by the goal to see scientific breakthroughs bring benefits to patients sooner. CDD is the sponsor of early phase and precision medicine clinical trials in oncology agents. Our broad portfolio rivals that of a medium-sized pharmaceutical company, spanning antibodies, cell therapies, vaccines, drug conjugates and small molecules, making this an interesting and dynamic area to work in.

As part of the Medical Writing team, the Medical Writing Associate will provide support to produce Clinical Study Reports (CSRs), Investigator Brochures (IBs) and clinical trial results reporting on public registries, including quality control (QC), compilation of documents and filing. You will provide support to the Medical Writing team for priority and complex projects, such as platform trials and trials conducted in both the UK and the EU. This role will predominantly support our DETERMINE platform trial.

It is an exciting time for CDD as we’re expanding our teams to move forward with an ambitious new strategy to maximise the impact of our research to benefit patients. Several teams are hiring new roles to make this new strategy a reality, expanding the size of our project portfolio and bringing in new skills as we work more internationally.

What will you be doing?

Review and QC of CSRs, IBs and other regulatory documents.

Write assigned sections of CSRs and IBs under supervision.

Support registration of clinical trials and results reporting on public registries, including populating templates and QC.

Support the Medical Writing team with maintaining and reviewing Trial Master Files (TMFs).

Compile and format regulatory documents and support the maintenance of document templates.

What are we looking for?

Educated to a minimum of Bachelor’s degree level (or equivalent) in a scientific discipline.

Excellent proofreading skills and attention to detail.

Ability to review and QC documents to ensure they meet the project brief/specification and are scientifically and technically accurate.

Excellent communication (both written and verbal) skills.

Excellent organisational skills, able to prioritise and manage own time.

A good team player, but also self-motivated and able to work independently.

Experience in scientific/medical writing, early-phase clinical trials and/or oncology would be advantageous.

Our organisation values are designed to guide all that we do.

Bold: Act with ambition, courage and determination

Credible: Act with rigour and professionalism

Human: Act to have a positive impact on people

Together: Act inclusively and collaboratively

We’re looking for people who can believe in and embody these organisation values and can use them to drive forward progress against our mission to beat cancer.

If you’re interested in applying and excited about working with us but are unsure if you have the right skills and experience we’d still love to hear from you.

We create a working environment that supports your wellbeing and provide a generous benefits package, a wide range of career and personal development opportunities and high-quality tools.

How do I apply?

We operate an anonymised shortlisting process in our commitment to equality, diversity and inclusion. CVs are required for all applications but we won’t be able to view them until we invite you for an interview. Instead, we ask you to complete the work history section of the online application form and answer the screening questions for us to be able to assess you fairly and objectively.

One of our values at CRUK is Being Human. Whilst we understand that AI has its benefits, we want to hear about why you’re personally interested in CRUK and what is motivating you to apply. We have noticed some applicants being less successful in their applications when using AI due to lack of real-life examples. To level the playing field and ensure fairness for all candidates, we strongly encourage responses to be written in your own words, drawing from personal experiences and knowledge. We discourage the use of AI when completing your application form and throughout the process.

We want to see every candidate performing at their best throughout the job application process, interview process and whilst at work. We therefore ask you to inform us of any concerns you have or any adjustments you might need to enable this to happen. Please contact [email protected] or 020 3469 8400 as soon as possible.
