Abstract

Insights

The Research to Accelerate Cures and Equity (RACE) for Children Act effectively mandates pediatric trials for new molecularly targeted cancer drugs. Early data shows increased pediatric trial requirements, fostering innovation in pediatric cancer therapies.

Area of Science:

  • Oncology
  • Pediatric Medicine
  • Regulatory Science

Background:

  • The Research to Accelerate Cures and Equity (RACE) for Children Act of 2017 enables the FDA to mandate pediatric clinical trials for new oncology drugs targeting relevant molecular pathways.
  • This legislation aimed to address gaps in pediatric cancer drug development.

Purpose of the Study:

  • To evaluate the impact of the RACE Act on the development of molecularly targeted oncology drugs for pediatric cancers.
  • Assessing changes in pediatric trial requirements post-RACE Act implementation.

Main Methods:

  • Review of FDA oncology drug approvals between August 18, 2020, and August 18, 2021.
  • Analysis of drug approval packages, letters, and prescribing information for submission/approval dates, indications, molecular targets, and pediatric trial requirements.

Main Results:

  • Of 17 new oncology drugs approved, 5 were submitted after the RACE Act's effective date.
  • 60% of post-RACE Act submissions required pediatric trials, compared to none of the pre-RACE Act submissions.
  • 83.3% of pre-RACE Act submissions had molecular targets that would have qualified under the Act.

Conclusions:

  • The RACE Act appears effective in closing legislative loopholes and promoting innovation for childhood cancer therapies.
  • Early evidence indicates a positive impact on the development of targeted oncology drugs for pediatric use.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
