Question: A company is developing a novel asthma inhaler, including both a new asthma drug and a novel nebulizer to deliver the drug. The product is intended to be used for asthma sufferers aged between 14 and 20 years old. The company has conducted a phase I clinical trial and demonstrated the product to be safe and now plans a phase II trial which will involve recruitment of trial participants of the relevant ages who suffer from asthma. Your answer must address the age of the intended participants and should also consider the following: c) How capacity to consent is defined and assessed. [12 marks]
When conducting a phase II clinical trial for a novel asthma inhaler targeted at asthma sufferers aged between 14 and 20 years old, it is essential to consider the age of the participants and address the issue of capacity to consent. The age range of the target participant group encompasses minors as well as young adults, and this age variation may impact the capacity to consent. Capacity to consent is the ability of a trial participant to understand relevant information, appreciate the consequences of their decision, and make an informed, voluntary choice to either participate or decline participation in the clinical trial. The assessment of capacity to consent is crucial to ensure the ethical conduct of clinical research, as it ensures that individuals are taking part in the study based on their informed decisions, and their autonomy is respected. To assess the capacity to consent in potential participants of the phase II clinical trial, there are several aspects to consider: 1. Age and Legal Regulations: It is important to adhere to the age of consent laws in the country or region where the clinical trial is being conducted. Laws and regulations vary by jurisdiction, so ensure that you are familiar with the local rules governing consent. 2. Information Provision: Clearly explain the nature and purpose of the clinical trial, potential risks and benefits, alternative treatment options, duration of the study, and their rights concerning withdrawal from the trial at any time. The information should be provided in the appropriate format that suits the age group, such as using visual aids, simple language, or even digital tools (e.g., videos, online platforms) to facilitate understanding. 3. Assess Understanding: To determine whether a participant has the capacity to consent, evaluate their comprehension by asking open-ended questions on the content presented to them. This assessment can be conducted by a trained staff member or a specialized tool designed for this purpose. 4. Involving Parents/Guardians: For participants under the age of 18, consent should be obtained from their parents or guardians in addition to their assent (agreement to participate). Engage parents/guardians in the information provision process to ensure they understand the study's details and can support the participant in making a decision. 5. Ongoing Assessment: Capacity to consent may change over time, particularly in this age group. Regularly reassess participants' understanding throughout the study, and provide updates on any changes in the trial's risks and benefits. In conclusion, when planning a phase II clinical trial involving participants aged between 14 and 20 years old, it is crucial to address the capacity to consent. This can be achieved by considering legal regulations, providing clear and age-appropriate information, assessing participants' understanding, involving parents/guardians for minors, and continuously evaluating consent capacity throughout the study. By following these steps, the research team can ensure that the trial is ethically conducted and that the autonomy of the participants is respected.
