To translate complex immunotherapy science into real-world clinical practice through engaging, high-quality education that supports clinicians, empowers patients, and improves outcomes.
Our vision is to become a trusted platform for immunotherapy education and discussion, helping bridge the gap between advanced scientific knowledge and everyday clinical practice.
We strive to create a space where learning is continuous, collaborative, and accessible to all.





We are medical oncologists and best buddies with a shared interest and passion for cancer immunotherapies, both the amazing outcomes achieved and the day to day challenges the pose. We love nothing more than a chat with friends and colleagues about all thing’s immunotherapy with Ricky despairing of Anna’s love for all things pharmacology and Anna marvelling at Ricky’s long held desire to give immunotherapy in the pub!
A dedicated series created for patients and their loved ones, breaking down immunotherapy into simple, understandable conversations.
From how treatment works to managing side effects and what life looks like during and after therapy, these episodes are here to help you feel informed, reassured, and supported.
From the outset, the focus was deliberately different.
Rather than purely discussing trial data, Immunobuddies focused on:
The format was conversational, honest, and grounded in day-to-day clinical experience — designed to feel like the discussions clinicians have in corridors, MDTs, and on-call shifts.
What started as a small educational project quickly grew.
The podcast has now reached over 108,000 downloads across more than 120 countries, connecting a global community of clinicians navigating the same challenges. Episodes span tumour types, toxicity management, biomarkers, emerging therapies, and complex case discussions — creating a comprehensive, evolving library of immunotherapy education.
Alongside this growth, Immunobuddies has become closely aligned with the wider work of the Immuno-Oncology Clinical Network (IOCN), contributing to a broader ecosystem of education that includes national webinars, case-based discussions, and face-to-face learning events. Together, these initiatives aim to reduce variation in care, improve early recognition of toxicity, and ultimately enhance patient safety.
Importantly, the podcast has also expanded beyond clinicians.
A dedicated patient series was developed to provide clear, accessible information for patients and their families — recognising that understanding treatment is a key part of navigating the cancer journey.
At its heart, Immunobuddies remains grounded in its original purpose:
to make immunotherapy more understandable, more accessible, and safer for patients.
It reflects a belief that education doesn’t need to be complicated to be impactful — it needs to be relevant, practical, and shared. And perhaps most importantly, it reflects the idea that no one should be navigating immunotherapy alone.
Anna Olsson-Brown is a Professor of Clinical Cancer Trials and a Consultant in Medical Oncology. She specialises in the systemic treatment of skin cancers; immunotherapeutic toxicities, early phase/translational clinical trials and NSS/CUP/acute oncology. She is an academic consultant at University College Cork/Cork University Hospital and works in the UK as an honorary academic at the University of Liverpool, an oncotoxicity consultant at University Hospitals Sussex, and within clinical leadership roles with both the Surrey and Sussex and West Midlands Cancer Alliances.
She has a background in clinical pharmacology and an interest in acute oncology and supportive care for cancer patients particularly with regards to toxicity of cancer therapies. She was an MRC research fellow completing her PhD investigating the mechanisms of immunotherapy toxicity and has subsequently published extensively in the area (Olsson-Brown – Search Results – PubMed (nih.gov)). She has established and led numerous acute and supportive oncology services including pan-tumour, pan-regional immunotherapy/oncotoxicity service supporting inpatients and outpatients with immunotherapy toxicities and providing a clinical-research interface supporting a number of translational trials at both the Clatterbridge Cancer Centre, Liverpool and Sussex Cancer Centre, UHSx. She sits on number of advisory panels including the Cardio-oncology MDT at the Liverpool Heart and Chest Hospital and Neuro-oncology toxicity and HLH MDTs at University College London Hospital. She has established both an enhanced supportive care service and an oncofraility service at UHSx. She spent 4 years as an Clinical Director in healthcare prior to taking up her academic position.
She is the current Chair of the Association of Cancer Physicians/ UK Society of Medical Oncology (ACP/UKSMO). She is a founding member and current CEO of the National Immunotherapy Clinical Network (IOCN). She is also the Toxicity Workstream Co-lead within the UK Acute Oncology Society and a trustee and board member of UKASCC. She is a Fellow of the Royal College of Physicians of Edinburgh and the current Oncology representative of the Symposium Committee at RCPE. She sits on the UK SACT board and RCP Oncology Committees in her representative roles.
