According to the Centers for Disease Control and Prevention (CDC), 1 in 38 8-year-olds is diagnosed with autism spectrum disorder (ASD). While a child’s autism diagnosis can answer questions, it may also prompt new ones for parents and caregivers. Often, families begin to consider next steps for the children in their lives, with many unaware that autism clinical trials are even an option. In fact, there is a wide variety of clinical trials that give participants access to emergent therapies.
Participation in autism research studies is always voluntary, and to ensure patient safety, protocols are in place to address informed consent and the rights of both children and their families. Understanding clinical trial options can help caregivers make informed, intentional decisions for the children in their lives.
Autism clinical trials are research studies designed to help better understand autism and evaluate potential supports, therapies, or interventions. Studies can include individuals on the autism spectrum across a wide age range.
Many studies have specific eligibility requirements, like receiving a formal diagnosis, being within a specific age range, or taking certain medications. Other trials may focus on specific needs such as communication, behavior, sleep, or mental health.
Clinical trials for autism fall into two main categories: interventional trials that study new treatments and therapies, and observational studies that collect specific data.
Participants are often closely monitored throughout the study, sometimes more than in typical care settings. While involvement in a clinical research study can offer access to new approaches and contribute to scientific progress, participation is always voluntary, and individuals may choose to leave a study at any time.
Clinical trials for autism are important because they ensure the safety of new medications and treatments and advance science. Ritu Goel, MD, is an integrative psychiatrist and founder of MindClaire, where she blends traditional psychiatry with holistic, personalized approaches to mental healthcare. Dr. Goel believes that it’s important to meet families where they are, to ensure clinical trial success.
Medical mistrust, which is often rooted in historical injustice and unequal treatment, can make some Black families hesitant to participate in clinical trials. Other barriers, such as limited access to specialized care, logistical challenges, and lack of insurance, can further prevent diverse representation. Addressing these concerns is essential to ensure clinical trials are more inclusive and that research reflects the needs of all.
“Most of the families I work with in underserved communities have never even heard of clinical trials as an option for their child,” Dr. Goel says. “That’s a failure on our end as researchers, not theirs. The outreach must happen where families already are, through pediatricians they trust, community organizations, and faith-based spaces. And researchers need to show up in those communities before they need something, not just when they’re trying to fill enrollment.”
Autism clinical trials involve a wide range of participants, including individuals on the autism spectrum, neurotypical individuals, and caregivers, with studies spanning from early childhood through adulthood.
Eligibility often depends on factors such as receiving a formal diagnosis, falling within a specific age range, and maintaining stable medication use. Participation may require in-person visits or be conducted remotely, and common exclusions include severe psychiatric or medical conditions.
These studies can be interventional (testing treatments) or observational (gathering data through surveys or imaging), and all participation is voluntary, with the option to withdraw at any time.
Families must manage expectations when considering participation in autism research studies. If a child meets eligibility criteria, there is no guarantee that they will receive the medication or treatment.
In a clinical trial, the researcher’s goal is to determine whether a treatment or drug actually works. They do this by comparing results across groups: one group of participants receives the treatment or variable, while another may receive a placebo. By comparing outcomes between the two groups, researchers can determine whether the treatment is effective and identify the differences in results.
“I’m always very direct with families about this, explaining that there is a real chance your child will not receive the treatment. None of us will know, including me as the investigator,” Dr. Goel tells BlackDoctor. “That’s how the study is designed. In practice, this means everyone involved needs to remain honest in their observations and not see improvement just because they want to.”
Although some families may worry that their child will be assigned to the placebo group, Dr. Goel reassures them that all participants are closely monitored, regardless of whether they receive the treatment. In many cases, this level of monitoring is more thorough than what they would typically receive in standard care.
Below are some potential benefits and risks of participating in autism research.
According to Autism Speaks, Black children are often diagnosed with autism later than white children — often over three years after their parents first express developmental concerns. “What I see over and over in my practice is Black children labeled with ODD or a ‘behavior problem,’ when what’s going on is undiagnosed autism,” Dr. Goel explains.
“One study shows Black children are more than five times more likely to be misdiagnosed with conduct disorder before anyone considers autism,” she adds. “By the time these families get to me, they’ve lost years.” Dr. Goel encourages parents to trust what they’re seeing in their child and to advocate for a comprehensive developmental evaluation until they receive satisfactory answers.
Finding the right autism clinical trial can feel overwhelming at first, but it becomes much more manageable once you know where to look and what to prioritize. Whether you opt for a study facilitated by a university, hospital, or independent research organization, autism clinical trials will vary.
This short list of resources is a great place to start, but it is important to review eligibility criteria and consider the location and commitment required to ensure the trial fits into your family’s lifestyle.
This list is not exhaustive, and new clinical trials for autism are continually emerging as research evolves. Because every child has unique needs and circumstances, it is important to consult your child’s healthcare provider when considering participation in a study. They can assist you in evaluating potential trials, determining eligibility, and weighing the pros and cons of participation.
“In my clinical practice, I see that presentations can differ, the diagnostic process can vary, and families face different barriers,” Dr. Goel explains. “Without including Black children in research, we are not truly developing care for this community, but we’re just borrowing data and hoping it fits. This needs to change.”
Ultimately, participating in autism spectrum disorder research studies allows families to gain access to opportunities and care they might otherwise not receive. And, while this sounds promising, it’s important to realistically consider the logistics and your comfort level with the risks presented.
