MIAMI (AP) – Dr. Alfonso Sabater, a renowned expert in the field of dermatology, proudly displayed two photographs depicting the transformation of Antonio Vento Carvajal’s eyes.
The first image depicted his eyes covered in cloudy scars, symbolizing the challenges he faced as he navigated through life with limited vision.
However, the second photo, taken after months of a revolutionary gene therapy through eyedrops, revealed a remarkable absence of any scarring.
Antonio, a teenager whose world had been shrouded in darkness due to a rare genetic condition known as dystrophic epidermolysis bullosa, experienced a glimmer of hope as he regained his sight.
This groundbreaking topical gene therapy, trialed for the very first time, had previously shown promising results in improving Antonio’s skin condition.
Driven by the success of this treatment, Dr. Sabater pondered whether it could be adapted to address the challenges faced by Antonio’s eyes.
Dystrophic epidermolysis bullosa is a debilitating disorder characterized by the formation of painful blisters throughout the body, including the delicate tissues of the eyes.
Antonio’s participation in the clinical trial had already brought about transformative changes in his skin, but Dr. Sabater’s insight sparked a new possibility – restoring his vision as well.
With enthusiasm and optimism, Dr. Sabater embarked on a journey to adapt the topical gene therapy specifically for Antonio’s eyes.
This innovative approach involved delivering the therapeutic genes through carefully formulated eyedrops.
Months of meticulous research and monitoring followed as Antonio underwent this groundbreaking treatment, providing newfound hope for his visual impairment.
The fruition of this pioneering endeavor was unveiled through the photographs before us today. Antonio’s eyes, once marred by the scars of his genetic condition, now appeared clear and unblemished.
Through the power of gene therapy, the darkness had been lifted, and Antonio could perceive the world around him in all its glory once again.
Dr. Sabater’s groundbreaking adaptation of the world’s first topical gene therapy for Antonio’s eyes not only offers hope to countless others suffering from similar conditions but also paves the way for further advancements in the field of ocular medicine.
This remarkable achievement serves as a testament to the tireless dedication of medical professionals and the transformative power of scientific breakthroughs.
As Antonio embraces this newfound gift of sight, he looks towards a future brimming with endless possibilities.
Through the unwavering commitment of Dr. Sabater and his team, hope is kindled for a future where blindness no longer remains an insurmountable obstacle.
This insight not only brought immense relief to Antonio, but it also paved the way for potential therapies that could potentially benefit millions of individuals suffering from various eye conditions, including common ones.
During a visit to the University of Miami Health System’s Bascom Palmer Eye Institute, Antonio’s mother, Yunielkys “Yuni” Carvajal, couldn’t help but become emotional when reflecting on what Dr. Sabater had done for her son.
Speaking in Spanish, she expressed her gratitude, stating, “He has been there through it all. He is not only an exceptional doctor but also a genuinely compassionate individual who offered us hope. He never gave up on Antonio.”
The family had arrived in the United States from Cuba in 2012, granted a special visa to seek treatment for Antonio’s relatively rare condition, affecting a mere 3,000 individuals worldwide.
Despite numerous surgeries to remove scar tissue from his eyes, the tissue would regrow, causing Antonio’s vision to progressively worsen. Eventually, he felt unsafe even walking around.
During this trying period, Sabater had no immediate answers, but he reassured the young boy, promising, “I will find a solution. I just need some time. Rest assured, I am working tirelessly towards it.”

“‘Yeah, I know you’re going to do it,’” Sabater recalled Antonio saying. “That gave me the energy to continue.”
During their journey, Carvajal informed Sabater about the availability of an experimental gene therapy gel designed for treating Antonio’s skin lesions.
Intrigued by the possibility of applying it to the boy’s eyes, Carvajal reached out to Krystal Biotech, the pharmaceutical company responsible for the development of the gel, to inquire about the feasibility of reformulating it for this purpose.
Suma Krishnan, co-founder and president of the company’s research and development division based in Pittsburgh, responded positively to the proposal.
She expressed that the idea appeared logical and emphasized that attempting the reformulation was worth a shot.
Antonio’s condition is caused by mutations in a specific gene that plays a crucial role in the production of a protein called collagen 7. This protein is responsible for holding together both the skin and corneas.
To address this issue, a treatment called Vyjuvek has been developed, which utilizes an inactivated herpes simplex virus to deliver functional copies of the gene.
In order to proceed with the treatment, the medical team underwent a rigorous process that involved extensive testing in mice over a period of two years.
Following the success of these tests, they obtained “compassionate use” approval from the U.S. Food and Drug Administration, along with the necessary permissions from university and hospital review boards.
Consequently, in August of last year, Antonio underwent surgery on his right eye, followed by the administration of the eyed
Antonio’s eye has fully recovered from the surgery and there has been no recurrence of scarring. In fact, there has been significant improvement noted every month, according to Sabater.
Recently, doctors assessed Antonio’s right eye vision, which was found to be near-perfect at 20/25.
year, Sabater commenced treatment on Antonio’s left eye, which had even more scar tissue. However, much to their satisfaction, there has been a steady improvement in his vision, with measurements coming close to 20/50 – a considerable achievement, as Sabater described it as “pretty good vision”.
Antonio visits the eye institute nearly every week for regular checkups and receives drops once a month.
These visits are crucial as Antonio, like other children with his condition, known as “butterfly children,” has extremely delicate skin, making him prone to injuries from the slightest touch.
Even now, as Antonio continues to use the skin gel, which was authorized by the FDA in May and can be applied to the eyes off-label, he understands that it is not a one-time treatment like most gene therapies.
Unlike gene therapies that alter DNA and provide permanent relief, the gel does not modify DNA and therefore necessitates regular application.
Sabater, director of the Corneal Innovation Lab at the eye institute, believes that gene therapy eyedrops have the potential to revolutionize the treatment of various diseases.
By altering the gene delivered by the virus, these eyedrops could be used to target other ailments besides thenea.
One example is Fuchs’ dystrophy, a condition that affects a staggering 18 million Americans and is responsible for nearly half of the corneal transplants in the nation.
Gene therapy eyedrops could potentially be used to treat this condition by introducing a different gene that specifically combats Fuchs’ dystrophy.
The implications of expanding the application of gene therapy eyedrops to treat a wider range of diseases are undeniably exciting.
Dr. Aimee Payne, a respected dermatology professor at the University of Pennsylvania, expressed her enthusiasm for this approach, stating that it directly addresses the underlying cause of the disease.
This signifies a potential breakthrough in the medical field, as gene therapy has the power to tackle the root cause of a disease rather than merely managing its symptoms.
In conclusion, the prospect of using gene therapy eyedrops to treat diseases other than corneal conditions is generating buzz among experts and researchers.
The ability to modify the gene delivered by the virus opens up new possibilities for combatting various ailments, such as Fuchs’ dystrophy.
This exciting approach offers promising potential for addressing the root cause of diseases, bringing hope to millions of people worldwide.
With his vision restored, Antonio has been able to indulge in a typical teenage pastime that he had longed to do for quite some time: playing video games with his friends.
The joy and satisfaction he feels from this experience are immeasurable. Moreover, he finally feels secure and confident while walking around, knowing that he can fully perceive his surroundings.
Sabater, the dedicated and persistent individual, expressed his belief that the arduous two-year journey to obtain government and hospital approvals for Antonio’s treatment was unquestionably worthwhile.
The immense impact it has had on Antonio’s life makes every effort made during this process more than worthwhile.
However, Sabater further emphasizes that the significance of this achievement is not limited to just Antonio’s personal improvement. It also paves the way for potential treatment opportunities for other patients in the future.
In summary, Antonio’s renewed vision has opened up a world of possibilities for him, enabling him to embrace normal teenage activities and feel a newfound sense of safety while navigating his surroundings.
To Sabater, the journey to obtain the necessary approvals was a labor of love and perseverance, driven by the desire to enhance Antonio’s quality of life.
This triumph not only brings immeasurable happiness and fulfillment to Antonio but also holds promise for prospective patients who may benefit from similar treatments in the future.
