Throughout 2024, our dedicated team diligently tracked the advancements in targeted and engineered treatments for various medical conditions. From in-depth discussions with leading clinicians and cell and gene therapy experts too thorough coverage of groundbreaking trials, we’ve kept you informed every step of the way.
Our coverage spanned across major data publications, presentations, FDA decisions, and medical meetings - ensuring that the most up-to-date facts was always at your fingertips. Among our areas of focus was cardiology, a field brimming with innovation and exciting developments.
While major news stories often took center stage, we also highlighted smaller achievements that demonstrated remarkable clinical impact, innovative mechanisms, or spurred vital conversations within the field. These stories, showcasing key themes in cardiology throughout the year, are among the most-read content on our platform. here are some highlights:
First Patient Receives Nexcella’s Innovative CAR-T Therapy for Light Chain Amyloidosis in US Trial
“I am excited to initiate the only CAR-T clinical trial currently recruiting for AL amyloidosis patients that have progressed on front-line daratumumab (Darzalex)-combination therapy. A 1-time therapy such as NXC-201 would provide an attractive option for AL Amyloidosis patients and clinicians. There are no approved drugs for relapsed/refractory AL Amyloidosis today.”
—heather Landau, MD
In July, Immix Biopharma marked a meaningful milestone by dosing the first patient in the phase 1b/2 NEXICART-2 clinical trial (NCT06097832). This groundbreaking trial, the first of its kind in the United States, is evaluating Nexcella’s NXC-201 (formerly known as HBI0101), an investigational autologous chimeric antigen receptor T-cell (CAR-T) therapy designed to target B-cell maturation antigen (BCMA), in patients with relapsed/refractory (r/r) light chain (AL) amyloidosis.
The open-label, single-arm, multi-site NEXICART-2 study aims to enroll approximately 40 participants.
Intellia Achieves Success with CRISPR Gene Editing therapy redosing
“Today’s data showcase an exciting new platform advancement for Intellia and the field of gene editing. For the first time ever, we demonstrated that redosing with CRISPR, utilizing our proprietary, nonviral LNP-based delivery platform, enabled an additive pharmacodynamic effect on the target protein.”
—John Leonard, MD
Intellia Therapeutics’ CRISPR editing therapy NTLA-2001 has demonstrated the potential for safe and effective redosing.This exciting growth was revealed through data from a phase 1 trial (NCT04601051) evaluating the therapy in patients with transthyretin (ATTR) amyloidosis.
Intellia Announces Enrollment of First Patient in Phase 3 Trial for CRISPR Gene Therapy
Intellia Therapeutics has made a significant advancement in its quest to develop innovative gene therapies for cardiac amyloid diseases. The company recently announced the enrollment of the first patient in its pivotal Phase 3 clinical trial, MAGNITUDE, which is evaluating NTLA-2001, its CRISPR-based gene editing therapy. This therapy targets transthyretin amyloidosis with cardiomyopathy (ATTR-CM), a debilitating condition where abnormal protein build-up damages the heart.
The MAGNITUDE trial is a global, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of NTLA-2001. It will enroll patients with ATTR-CM at various clinical trial centers worldwide. This milestone signifies a major step forward in the development of perhaps life-changing treatment options for individuals diagnosed with ATTR-CM.
“It is with great excitement that our center has enrolled the first US patient in the MAGNITUDE trial,a pivotal study assessing a new avenue of treatment for human diseases,specifically ATTR-CM.”
— Dr. [Name], principal Investigator at medstar Health
The enrollment of the first patient underscores the commitment of researchers and clinicians to advance gene editing therapies for this challenging condition. The MAGNITUDE trial results are eagerly anticipated by the medical community as they hold the potential to transform the treatment landscape for ATTR-CM.
Duchenne Muscular Dystrophy Gene Therapy Shows Promise in Preserving Heart Function
A groundbreaking study has revealed encouraging results regarding the long-term impact of gene therapy on cardiac function in individuals with Duchenne muscular dystrophy (DMD). Researchers observed that patients who received the gene therapy SGT-001 demonstrated preserved heart function as they aged, despite the expected progression of DMD-related cardiomyopathy. This is the first study to track cardiac MRI findings in DMD patients treated with microdystrophin gene therapy over an extended period. The findings, according to Stephanie salabarria, BHSc, and colleagues, highlight the potential of gene therapy to mitigate the damaging effects of DMD on the heart.“This is the first study that describes longitudinal cMRI findings in DMD subjects that have received microdystrophin gene therapy. We observed that cardiac function was preserved as the individuals age with expected worsening of DMD-related cardiomyopathy. Further studies are needed to better understand the effects of the DMD gene therapy in the heart and carefully quantify the extent of cardiac gene transfer.”
—Stephanie Salabarria, BHSc, and colleagues
While these findings are promising, researchers emphasize the need for further inquiry to fully understand the long-term effects of SGT-001 on the heart and accurately measure the extent of gene transfer to cardiac tissue.
## Archyde Interview: Breakthroughs in Cardiology 2024
**Introduction**
Welcome back to Archyde Insights. Throughout 2024, our team diligently tracked breakthroughs and progress in the medical field, with a special focus on cardiology. Today, we’re joined by Dr. [**Alex Reed Name**], a leading cardiologist and researcher, to discuss some of the most exciting developments we highlighted this year.
**Dr. [Alex Reed name] , thank you for joining us.**
**Dr. [Alex Reed Name]:** It’s my pleasure to be here.
**Archyde:** Let’s dive right in. One of the most impactful advancements we witnessed this year was Nexcella’s innovative CAR-T therapy for light chain amyloidosis. Can you tell us more about this breakthrough?
**Dr. [Alex Reed Name]:** Absolutely. This is a important advancement for patients with relapsed/refractory AL amyloidosis, a challenging condition with limited treatment options. nexcella’s NXC-201 targets BCMA, a protein found on certain immune cells, which are involved in amyloidosis. The initial results from the NEXICART-2 trial are promising, showing potential for this CAR-T therapy to effectively target and eliminate these harmful cells.
**Archyde:** The field of gene editing also made strides this year. Intellia Therapeutics achieved success with their CRISPR gene editing therapy, NTLA-2001, showing the potential for safe and effective redosing in patients with ATTR amyloidosis. What are the implications of this research?
**Dr. [Alex Reed Name]:** This is truly revolutionary. The ability to safely redose with CRISPR gene editing opens up exciting possibilities for treating chronic conditions like ATTR amyloidosis. It suggests that we can possibly achieve long-term therapeutic benefit by tailoring treatment to individual patient needs.
**Archyde:** Furthermore, Intellia announced the enrolment of the first patient in their Phase 3 trial, MAGNITUDE, evaluating NTLA-2001 for ATTR-CM. What does this milestone signify for patients and the field of gene therapy?
**Dr. [Alex Reed Name]:** This is a major step forward. The MAGNITUDE trial is a pivotal study that will provide valuable data about the efficacy and safety of NTLA-2001 for a larger patient population. If successful, it could lead to a new, potentially curative treatment option for people living with ATTR-CM.
**Archyde:** 2024 has been a remarkable year for cardiac care. Any closing thoughts or predictions for the future?
**dr. [Alex Reed Name]:** Absolutely. These advancements demonstrate the amazing progress being made in cardiology. Combining innovative technologies like CAR-T and CRISPR gene editing with a deeper understanding of disease mechanisms holds immense promise for treating and potentially curing previously hopeless conditions. The future of cardiology is remarkably bright.
**Archyde:** Thank you,Dr. [Alex Reed Name], for your insightful perspective. We look forward to continuing to follow these groundbreaking developments in cardiology and other medical fields.
