Oncology patient recruitment

Having supported 50+ oncology studies, we know how difficult the oncology space can be. 

For years, sponsors have been experiencing costly, inefficient, and increasingly difficult-to-scale recruitment. While you continue to pursue the next breakthrough cancer treatment, we’re actively piloting our potential breakthrough oncology recruitment model, built on 20 years’ experience and the patient voices of thousands of oncology patients.

In a market with 24,300+ clinical trials targeting a limited pool of patients, compounded by the previously immovable barriers to recruiting patients for oncology clinical trials, now is the time to speak to Clariness about your study. 

More patients, same problems

Cancer diagnoses are projected to grow by 75% to 35M annual cases in 2050, yet only <3% of the patient population have ever joined a trial. 

  • 4–12-week diagnosis-to-treatment windows make timing everything 
  • Physicians refer just 0.2% of their patients into clinical trials 
  • >20% of sites fail to enroll a single oncology patient 

It’s no surprise why oncology trials fail to reach their minimum enrollment targets 2-4x more often than other therapeutic areas. Luckily, Clariness has 20 years’ experience closing the gap between your targets and eligible patients.

Oncology case study

Spotlight: Clariness campaign pushed >300,000 patients to ClinLife®

Project overview:

  • Online patient recruitment for a Phase III anaplastic astrocytoma study (rare) 
  • 6 countries (AU, DE, ES, PL, RU, US) with 53 sites, over 51 weeks 
  • Our approach included online awareness campaigns, a pre-qualification process, direct scheduling of screening visits, and site helpdesks to optimize patient contact

Clariness can help you reach the right patients, at the right point of time

Between diagnosis and treatment decisions, patients have a window of just 4-12 weeks to explore all care options, including clinical trials.  

That’s why we developed our oncology service, which introduces Clariness Oncology Companions into the recruitment journey. 

Here’s how it works: 

  • Early patient engagement pre- and between diagnosis and treatment decisions 
  • Our dedicated oncology companions engage and guide patients, their support network, tumor board and HCPs to facilitate informed treatment decisions 
  • This engagement by a trained oncologist ensures your trial is well considered as a treatment option by the patient’s treating physician

Boost physician referrals for your oncology trials with our oncology companions.

Oncology FAQs

What are the biggest recruitment challenges in oncology clinical trials?

Oncology clinical trials often aim to recruit highly specific patient populations defined by cancer type, stage, line of therapy, biomarkers, and prior treatments. Rapidly evolving standards of care and competing clinical trials further reduce the pool of eligible participants. Clariness addresses these challenges through protocol-specific recruitment strategies, hybrid recruitment models, and close collaboration with study sites to improve referral quality. 

Many patients first learn about clinical trial opportunities through their treating physicians, making physician trust and engagement essential to oncology recruitment. Clariness works alongside study sites and referral networks to support physician engagement while complementing site-based recruitment with targeted patient outreach where appropriate.

Clariness supports a wide range of oncology indications including breast cancer, leukemia, lung cancer, renal cell carcinoma, anaplastic astrocytoma, lymphoma, Glioblastoma, ovarian cancer, metastatic pancreatic adenocarcinoma, melanoma, multiple myeloma, and many others. 

For many patients, the period between cancer diagnosis and treatment decisions is the only opportunity to consider a clinical trial. Once treatment begins or the disease progresses, patients may no longer be eligible. Clariness helps sponsors engage patients early through targeted recruitment strategies that maximize this critical recruitment window.

Many precision oncology studies require patients with specific genetic mutations or biomarker profiles, making recruitment increasingly complex. Clariness incorporates protocol-specific biomarkers and line-of-therapy requirements into its recruitment and pre-screening strategies to help identify eligible participants while reducing unnecessary site burden.
