As of February 2025, there are more than 150 clinical trials using CRISPR technology

The first CRISPR-approved treatment was for sickle cell anemia in 2023

Victoria Gray was the first patient to receive a CRISPR-based therapy, which eliminated her symptoms and restored her health. The therapy's initial cost of $2.2M has kept it out of reach of many patients.

CRISPR is a gene-editing tool that lets scientists cut out and replace damaged DNA

One of the most significant advances in modern medical science, CRISPR is a molecular tool for making precise changes to a gene's DNA. The technology has already been approved for treating sickle-cell disease.

Restoring vision in impaired patients via CRISPR

Since CRISPR was revealed as a gene editing tool in 2012, it has been on an accelerated track to real-world applications. Among other clinical demonstrations, doctors have now injected a CRISPR treatment directly into eye cells, helping vision-impaired patients see shapes and colors again.

A deeper (nontechnical) dive into how CRISPR works

Extra crispy? No, it's CRISPR, but this gene-editing technology is "extra" in the sense of being momentous and destined to change everything. Through CRISPR, scientist exploit a quirk in bacteria immune systems, allowing them to potentially, and quickly, control genes, remove undesirable traits, and add preferred ones. The possibilities and applications are endless.

Visualize how CRISPR-Cas9—a type of immune system used by single-celled organisms to attack invasive viruses—targets and makes precise changes to a gene's DNA.

There are more than 1,400 listed clinical trials for macular degeneration

The US database of clinical trials listed more than 1,400 macular degeneration trials in early 2026. That doesn't mean every trial is recruiting, but it does indicate there is significant interest in this medical condition.

Early research suggests CAR-T therapy might treat scleroderma, reducing skin thickening

Clinical data from a couple patients in 2025 indicated that one experimental CAR-T therapy called rese-cel was able to genetically reprogram T cells to eliminate certain problematic immune B cells that were causing the condition. The therapy reduced skin thickening and allowed the patients to halt using immunosuppressive medications and steroids.

A clinical trial is underway in 2026 to help kidney transplant recipients avoid a lifetime of immunosuppressing drugs

This later-stage clinical trial, in Chicago and Taiwan, evaluates the efficacy and safety of a new cellular therapy that may be swapped in for immunosuppressing drugs among kidney transplant recipients. The study randomizes people to either receive standard immunosuppressants or this cellular therapy and fewer immunosuppressants. It only includes kidney transplant recipients receiving organs from live donors so transplant surgery timing won't hinge on the unpredictable schedule of performing surgery and follow-up care when a donor dies.

Astronauts have repaired genetic damage in space using CRISPR—a molecular tool that can make precise changes to DNA and is used in single-celled organisms to attack invasive viruses.

Researchers are breeding genetically modified mosquitoes to be malaria-resistant

Using CRISPR, a team of international researchers is genetically modifying Anopheles in the lab to be malaria-resistant. The insects would be released into the wild to mate with the wild population, passing down this trait. As of early 2026 they had not yet released the mosquitoes into the wild for field trials. Separate CRISPR work seeks to reduce the Anopheles population altogether.

Stem cell therapies

Much of this research is done with support from the National Institutes of Health (NIH). This page offers a snapshot of research programs funded by the NIH and the health problems those programs focus on.

The US FDA considered mitochondrial replacement therapy during 2014 hearings

An agency committee assessed if this approach could have undesirable ripple effects across multiple generations and whether a clinical trial involving this approach would be appropriate. As of 2026, the US has continued to prohibit this procedure though it is legal in other settings including the UK and Australia.

A new daily MS pill is seeking regulatory approval in 2026

In clinical trials, Roche's fenebrutinib showed promise treating primary progressive MS and doubling relapse-free time in patients with relapsing MS as compared to existing treatment. But some liver damage and two possible drug-related deaths in the trials may make it difficult for the drug to net approval. (Some users may encounter a paywall.)

Trials ongoing for a 99% accurate, AI-powered blood test

The UK's National Health Service has launched a trial for a blood test that can detect a dozen types of cancers with just ten drops of blood. An AI tool looks for genetic material known to be released by tumors, allowing for cancer detection before tumors are large enough to be imaged.

Peptides account for 31 of 370 new drugs approved by US FDA between 2016 and 2023

Among the approved peptide-based drugs is the first-ever treatment for Rett syndrome, a rare inherited neurologic disorder that leads to a progressive loss of motor skills and language. Peptides are particularly attractive for multiple reasons, including their ability to selectively bind to cellular receptors to either activate or inhibit their function.

Scientific advances are unlocking a wide range of alternatives to IVF

From refined artificial insemination and microsurgical sperm extraction to experimental uterine transplants, scientific innovation is rapidly advancing potential fertilization technologies. But they come along with costly trials, some ethical dilemmas, regulatory issues, and more.

More than 200 drug trials for Alzheimer's have failed or been abandoned since 2010

The complexity of Alzheimer's disease, coupled with decades of underfunded research efforts, has left patients with little in the way of effective treatments. In recent years, scientists have synthesized several drugs that studies show can slow the progression of Alzheimer's—though the disease itself remains incurable.

The lack of diversity in clinical trials is undermining the future of precision medicine

Medicine works better when the treatments are tailored to fit each individual person’s biology and history. Homogeneous patient selection in clinical trials means treatments and care are being refined based on only a small range of variables, some of which may not apply to you. This 40-minute podcast episode discusses the historical and current reasons for the lack of clinical trial diversity and what this means for the future of personalized medicine.
