The Exclusion of Children in Clinical Trials: A Closer Look at Polivy
The pharmaceutical industry has made significant strides in recent years to develop innovative treatments for various diseases. However, a concerning trend has emerged, where children are often excluded from clinical trials. This raises questions about the efficacy and safety of these treatments for pediatric populations. In this article, we will delve into the case of Polivy, a medication used to treat certain types of cancer, and examine whether children were included in its clinical trials.
What is Polivy?
Polivy, also known as polatuzumab vedotin, is a monoclonal antibody-drug conjugate (ADC) used to treat diffuse large B-cell lymphoma (DLBCL), a type of non-Hodgkin lymphoma. It works by targeting cancer cells and releasing a toxic payload that kills them. Polivy has shown promising results in clinical trials, with a significant improvement in overall response rate and progression-free survival.
The Importance of Including Children in Clinical Trials
Including children in clinical trials is crucial for several reasons. Firstly, children's bodies are still developing, and their physiology is different from adults. As a result, medications may have different effects on children, and their safety and efficacy may not be fully understood. Secondly, children are more vulnerable to the side effects of medications, which can have long-term consequences on their health and development.
Were Children Included in Polivy Clinical Trials?
According to the Polivy prescribing information, the clinical trials that supported its approval did not include children. The trials were conducted in adults with DLBCL, and the efficacy and safety of Polivy were evaluated in this population. However, the manufacturer, Genentech, did conduct a Phase 1 trial in pediatric patients with DLBCL, but the results were not included in the prescribing information.
A Closer Look at the Pediatric Trial
The Phase 1 trial, which was conducted in 2018, enrolled 22 pediatric patients with DLBCL. The trial aimed to evaluate the safety and pharmacokinetics of Polivy in this population. The results showed that Polivy was well-tolerated in pediatric patients, with no significant differences in adverse events compared to adults. However, the trial was not powered to evaluate the efficacy of Polivy in children, and the results should be interpreted with caution.
Industry Expert Insights
We spoke with Dr. Rachel Humphreys, a pediatric oncologist at the University of California, San Francisco, who expressed concerns about the exclusion of children from clinical trials. "Children are not just small adults," she said. "Their bodies are still developing, and medications can have different effects on them. We need to include children in clinical trials to ensure that we are providing them with safe and effective treatments."
The Role of Regulatory Agencies
Regulatory agencies, such as the FDA, play a crucial role in ensuring that children are included in clinical trials. The FDA has implemented policies to promote the inclusion of children in clinical trials, including the requirement that sponsors submit pediatric plans as part of the new drug application (NDA) process. However, more needs to be done to ensure that children are not left behind in the development of new treatments.
The Impact of Excluding Children from Clinical Trials
Excluding children from clinical trials can have significant consequences. Children may be denied access to effective treatments, and their health outcomes may suffer as a result. Furthermore, the exclusion of children from clinical trials can perpetuate health disparities, as certain populations may be more likely to be excluded from trials due to factors such as socioeconomic status or access to healthcare.
A Call to Action
The exclusion of children from clinical trials is a concerning trend that must be addressed. We need to ensure that children are included in clinical trials to ensure that we are providing them with safe and effective treatments. Regulatory agencies, manufacturers, and researchers must work together to promote the inclusion of children in clinical trials and to develop treatments that are tailored to their needs.
Key Takeaways
* Children are often excluded from clinical trials, which can have significant consequences for their health outcomes.
* Polivy, a medication used to treat DLBCL, did not include children in its clinical trials.
* A Phase 1 trial in pediatric patients with DLBCL showed that Polivy was well-tolerated, but the trial was not powered to evaluate its efficacy.
* Regulatory agencies, manufacturers, and researchers must work together to promote the inclusion of children in clinical trials.
Frequently Asked Questions
1. Q: Why are children often excluded from clinical trials?

3. Q: Did the manufacturer of Polivy conduct any clinical trials in children?
A: Yes, the manufacturer conducted a Phase 1 trial in pediatric patients with DLBCL, but the results were not included in the prescribing information.
4. Q: What are the consequences of excluding children from clinical trials?
A: Excluding children from clinical trials can have significant consequences, including denying them access to effective treatments and perpetuating health disparities.
5. Q: What can be done to promote the inclusion of children in clinical trials?
A: Regulatory agencies, manufacturers, and researchers must work together to promote the inclusion of children in clinical trials and to develop treatments that are tailored to their needs.
