How to Conduct Effective Clinical Trials in Rare Cancers

If cancer affects a small fraction of the population, it is considered rare. Rare oncology is a branch of oncology that deals with malignancies with the lowest incidence rates, such as small cell cervical cancer. This means, even though the tumor is located in a common cancer-affected part of the body, the Veristat clinical trial design and treatment will necessitate a different therapeutic approach. Rare oncology can also refer to cancers that affect an area of the body rarely affected by cancer.

The Steps to a Successful Clinical Study in Rare Cancers

Rare cancer therapies and treatments are difficult to develop because of the low occurrence rate. Sometimes, rare malignancies are only discovered after other, more prevalent causes have been eliminated, which makes their treatment more difficult. The survival rate is so low that patients drop out of research trials or the treatments are abandoned in rare circumstances. Still, new therapies for people with rare cancers are desperately needed. Even then, effective clinical trial planning and studies can be achieved through;

Appropriate Diagnosis

Expert pathologists must make sure that clinical studies, as well as diagnoses, are done correctly. The study will not produce reliable results if the correct diagnosis of uncommon malignancies cannot be confirmed.

Putting the research into action

Even though the feasibility of a study is often used as a decision-making criterion, it faces several hurdles when it comes to rare malignancies. While assessing the feasibility in various nations, researchers employ a hands-on approach to maintain the momentum while looking for motivated scientists to counter this challenge. This approach also offers pre-screening consent, which helps identify a patient with uncommon cancer mutations. Additionally, patients in their first- or second-line chemotherapy during the pre-screening phase can choose to join the trial later on.

Balancing Inclusivity and efficiency

Another problem in clinical trials and ultimate drug approvals is balancing efficiency with inclusion. Medics must explore ways they can expand the pool of individuals who have access to these treatments. This can either be done through clinical trials or once they’re licensed, but especially as new drugs are created. For the past several years, the American Society of Clinical Oncology (ASCO) has been developing a framework to extend trial requirements. However, these criteria have increasingly become stringent over time, which is one of the reasons why approximately 3% to 5% of cancer patients participate in clinical studies.

Broaden eligibility criteria

Broadening patient eligibility criteria has several advantages; one being early access to new pharmaceuticals. Other benefits include earlier detection of therapies that may not be effective, more comprehensive safety and efficacy data, speedier trial enrolment, and generalizable outcomes. However, it can have drawbacks, such as increased heterogeneity, making it difficult to interpret data. Also, it could make it more difficult to identify efficacy signals and assess safety. Even then, patient safety concerns during clinical trials may necessitate more frequent patient monitoring.

to better understand rare cancers, the current research should make its results available to aid in future research. Additionally, rare cancer trials require cooperative networks and multinational effort since the target population is sometimes rather low.
