Italy has begun administering the first CRISPR-based treatment. The therapy for sickle cell disease and beta thalassemia (Casgevy) has already been delivered to four patients across three clinical centers within a month. The announcement was made during the conference “Italian Primacy in the Treatment of Hemoglobinopathies” held yesterday at the Senate.
For more information, we recommend Francesca Ceradini’s article in Osservatorio Terapie Avanzate.
Experimental patients often find themselves in a paradoxical situation: they must be sick enough to qualify for a clinical trial but healthy enough to endure its side effects. They also need the audacity to subject their bodies to protocols whose safety and efficacy remain unproven. For this reason, many describe them as pioneers or even warriors.

This photo shows the first American “non-experimental” patient leaving the hospital after completing the CRISPR-based treatment for sickle cell anemia (Casgevy). The New York Times detailed this “official first,” which followed the success of a clinical trial involving dozens of patients like Victoria Gray. We still know little about the first person who is beginning treatment in Europe since this therapy became an “approved drug”. According to Osservatorio Terapie Avanzate he is a young adult (23 years), who arrived in Italy in 2014 and living in the Umbria region, where is being also treated. Undergoing cell extraction and reinfusion of edited cells is an invasive and exhausting process, but now the American Kendric Cromer (12 years old) and other “first patients” can hope to lead full lives—without painful crises or blood transfusions. Best of luck!
Not only sickle cell anemia, now thalassemia as well. On January 16, the Food and Drug Administration completed the approval process for the second type of hemoglobinopathy too, while the European Medicines Agency is expected to give the green light in the coming months. It took just over a decade to go from the invention of the Cas9 genetic scissors to the first approved treatment, and the excitement over the milestone achieved in record time is more than justified. Yet an article in MIT Technology Review has already turned the spotlight on the next challenges. The title is, “Vertex developed a CRISPR cure. I’ts already on the hunt for something better”. Gentler conditioning for ex vivo gene editing, new vectors for in vivo delivery, and maybe even a pill mimicking the Casgevy mechanism without modifying DNA. This is how CRISPR researchers try to out-innovate themselves.
The approval of Casgevy, the new CRISPR option for sickle cell disease, is big news for American patients. The list price is high ($2.2 million) although lower than the non-CRISPR gene therapy approved by the FDA for the same pathology the same day. But in addition to economic sustainability, another issue worries scientists, clinicians, and patients: infertility.

In the story from the Bible King Solomon ruled between two women who both claimed to be the mother of a child. In the CRISPR saga the contention is between biotech companies over foundational patents, and the next crucial episode will unveil the consequences for the first CRISPR therapy, Casgevy.

The first Investigational New Drug (IND) application for base-editing technology has been cleared by the Food and Drug Administration. BEAM-101, developed by Beam Therapeutics, is an ex vivo base-editing product candidate, meaning that it uses a modified form of CRISPR capable of making single base changes without double-stranded DNA cleavage.

The Nobel Prize for CRISPR is one of the most exciting ever assigned in chemistry and one of the most celebrated in the media, for reasons related to the invention and the inventors alike. On the one hand, the technique is changing the practice and the image of genetic engineering. On the other hand, Jennifer Doudna and Emmanuelle Charpentier are not merely great scientists; they are a success story in cracking the glass ceiling and a symbol of the strength of collaboration.

Covid19 is affecting everyone, but it has hit the sickle cell (SCD) community particularly hard. According to STAT News the pandemic has temporarily stopped clinical trials and the introduction of new drugs, besides directly impacting SCD patients who are at high risk for severe complications from Sars-Cov2 infection and may need hospital assistance for SCD pain crises.
