If you are considering home-based pembrolizumab treatment, understanding the process from beginning to first injection helps you know what to expect and what decisions lie ahead. Here is a clear walkthrough of every step.
Step 1: The eligibility check
The process begins with our online eligibility questionnaire - a short form that gathers the clinical information an oncologist needs to make a meaningful preliminary assessment. It covers your cancer type, PD-L1 result, treatment history, and general health. It takes approximately three minutes to complete and can be saved and returned to if you need to gather information before finishing.
Every submission is reviewed by a qualified oncologist within 24 hours - not an algorithm. You will receive a clear response indicating whether you appear to be a suitable candidate, or explaining why this may not be the right route for you. There is no charge for this step and no obligation to proceed.
Step 2: Your Welcome Call
If your preliminary assessment is positive, the next step is a free Welcome Call with a member of our clinical team. This is a video call - typically 30-45 minutes - that covers your questionnaire results in detail, whether treatment could be an appropriate option, how the process works, and the costs involved. Your questions, whatever they are, are answered fully before any commitment is made.
The Welcome Call is not a sales conversation. Its purpose is to ensure you have the complete picture - clinical, practical, and financial - before deciding whether to go further.
Step 3: Full clinical assessment
If you decide to proceed after the Welcome Call, a more comprehensive clinical assessment is conducted. This includes a review of your full medical records (with your consent), confirmation of your PD-L1 result and other relevant biomarkers, a detailed review of your treatment history, and assessment of any factors relevant to home treatment suitability. This step confirms your eligibility formally and forms the basis of your personalised treatment plan.
Baseline blood tests are arranged at this stage, establishing your starting reference values for the monitoring that continues throughout treatment. A final clinical sign-off from the oncologist authorises treatment to begin.
Step 4: First treatment
Your supervising oncologist prescribes your pembrolizumab. The drug is sourced, dispensed, and delivered to your home at the correct temperature. A qualified oncology nurse visits at the agreed time, takes baseline observations, administers the subcutaneous injection, monitors you post-injection, and completes the clinical documentation. Your first treatment cycle is underway.
From that point, the rhythm of treatment - injection visit, blood test, remote check-in, repeat - becomes routine. The clinical team is available between cycles for any concerns, and your monitoring results are reviewed before each dose. The goal throughout is effective treatment, delivered safely, in the comfort of your own home.
The first step takes three minutes
Complete the eligibility check and an oncologist will review it within 24 hours. There is nothing to commit to - just a clear answer about whether this could be right for you.
