David Kirn, MD, Co-founder and Chief Executive Officer of 4DMT summarized 2023 and noted the company’s intended progress for the coming year in his statement. In the news release1 he said, “2023 was a landmark year for 4DMT, highlighted by rapid enrollment for 4D-150 in wet AMD and DME, strong CFTR protein expression data for 4D-710 in lungs of people with CF, multiple value-generating business development partnerships, and key additions to the Executive Team. Looking forward to 2024, we plan to release multiple important datasets from our lead programs in wet AMD, DME and CF. We also plan to share guidance on the design and timing of Phase 3 clinical trials. In addition, we expect to initiate clinical development of 4D-175 in geographic atrophy by the second half of the year. By the end of 2024, we intend to progress clinical development in four large market diseases, positioning us well in our strategy to become a fully integrated large market genetic medicines company.”

4D-150 for Wet AMD
According to the company's press release1, phase 2 PRISM Clinical Trial has a randomized Dose Expansion arm (N=50) in advanced high treatment need patients.
