Advantages

The specialized expertise you need

Our oncology CRO team is 1,000+ strong, including 45+ physicians with oncology experience, expertise in China and Japan, and recent key medical oncologist and ex-FDA appointments. Our clinical trial work is particularly noteworthy in the indications listed above, with experience with multiple cell and gene therapies as well.

More relationships, sites, and scale to accelerate study startup

We have access to nearly 2,500+ sites across Phase I-III solid tumors trials globally. From this number we have established strategic relationships with more than 220 solid tumor experienced sites that are part of Parexel Site Alliance network — sites that have achieved high levels of investigator satisfaction, improved number of patients recruited per site, and accelerated timelines thanks to the alignment of startup processes.

Driving trial design with patient insights

Through social listening, patient surveys, and patient burden analysis, we continually collect oncology patient insights to assess trial feasibility, improve study design, and identify risk. These practical, actionable insights help us to create more accessible trials, reduce trial amendments, increase enrollment, and improve the patient experience. These insights, when combined with our innovative recruitment and retention strategies, allow us to deliver results that exceed your expectations.

Expertise in trial design meets best-in-class technology

Our innovative approaches include adaptive designs; basket, umbrella, and platform studies; and model-based dose escalation trials. We also develop strong relationships with best-in-class partners pushing the boundaries of what technology can do. With innovations like artificial intelligence and machine learning, as well as streamlined data collection and reporting, we reliably deliver more efficient designs, site selection processes, recruitment strategies, and more.

An oncology CRO (Clinical Research Organization) is a specialized organization that provides support and services for conducting clinical trials in the field of oncology, which focuses on the diagnosis and treatment of cancer.

Oncology CROs assist pharmaceutical and biotechnology companies, as well as academic institutions, in various aspects of clinical research, including study design, regulatory compliance, site selection, patient recruitment, data management, monitoring, and analysis. They work closely with investigators, healthcare professionals, and patients to ensure that clinical trials are conducted in a safe, efficient, and ethical manner.

The main goal of an oncology CRO is to accelerate the development of new cancer treatments and therapies by effectively managing clinical trials. By leveraging their expertise in oncology research, these organizations help to advance scientific knowledge, improve patient outcomes, and contribute to the fight against cancer.
 

Precision oncology, also known as personalized or targeted oncology, is an approach to cancer treatment that involves tailoring therapy based on an individual's specific genetic, molecular, and clinical characteristics. It aims to identify the unique characteristics of a patient's tumor and choose the most appropriate treatment strategy to maximize effectiveness and minimize side effects.

Precision oncology relies on advances in genomic sequencing technologies and molecular profiling to identify specific mutations or alterations in a patient's tumor that drive cancer growth. These identified genetic or molecular abnormalities can be targeted with specific drugs or therapies that are designed to inhibit or exploit those particular alterations within the cancer cells.

It is important to note that while precision oncology has transformed the treatment landscape for some cancers, it is still an evolving field with ongoing research and clinical trials aimed at identifying new targets and improving patient outcomes.
