Rocket Pharmaceuticals Provides Regulatory Update on KRESLADI™ (marnetegragene autotemcel; marne-cel)
Rocket Pharmaceuticals (NASDAQ: RCKT) has received a Complete Response Letter (CRL) from the FDA regarding its Biologics License Application for KRESLADI™ (marnetegragene autotemcel; marne-cel), a gene therapy for severe leukocyte adhesion deficiency-I (LAD-I). The FDA has requested additional Chemistry Manufacturing and Controls (CMC) information. Rocket met with FDA leaders to expedite the approval process. The global Phase 1/2 study showed 100% overall survival at 12 months for all nine patients, with significant reductions in infections and improvements in LAD-I symptoms. KRESLADI™ was well tolerated with no serious adverse events reported.
- 100% overall survival at 12 months in global Phase 1/2 study.
- Significant reductions in serious infections and improvements in LAD-I symptoms.
- No treatment-related serious adverse events reported.
- FDA's collaborative approach to expedite approval.
- Received a Complete Response Letter (CRL) from the FDA requiring additional CMC information.
Rocket Pharmaceuticals' update regarding the FDA's Complete Response Letter (CRL) for KRESLADI™ (marnetegragene autotemcel, or marne-cel) provides important information about the progress of this lentiviral vector-based gene therapy. The FDA's request for additional Chemistry Manufacturing and Controls (CMC) data, while indicative of the regulatory hurdles, doesn't suggest problems with the clinical efficacy or safety of the therapy. Given the Phase 1/2 study's promising results—100% overall survival at 12 months post-infusion and substantial improvements in infection rates and wound healing—this news points towards eventual approval, albeit with a delay. For retail investors, this signifies strong potential for future stock appreciation, contingent on the timely submission and acceptance of the requested CMC information.
From a broader perspective, the FDA's quick and collaborative stance with Rocket Pharma underscores the importance they place on therapies for high unmet medical needs. This can be seen as a positive indicator for the biotech sector, where regulatory support can accelerate the path to market for innovative treatments.
While the immediate response from the FDA requiring additional CMC information adds a layer of uncertainty, it is important to note that this does not involve efficacy or safety concerns. This means Rocket Pharmaceuticals is likely to achieve approval once the CMC details are addressed. For investors, this temporary setback could present a buying opportunity, especially given the therapy’s potential to address severe leukocyte adhesion deficiency-I (LAD-I), a niche but high-need market.
Financially, the company's strong clinical data could translate into significant revenue streams post-approval. However, investors should be mindful of potential delays and the financial implications of addressing the FDA's queries. This might strain short-term cash flows but should be manageable given the high unmet need and the industry’s supportive regulatory environment.
Rocket met with FDA senior leaders from Center for Biologics Evaluation and Research (CBER) to align on the limited scope of additional CMC information needed to support the approval of KRESLADI™ as quickly as possible. “It is reassuring to have the FDA as a close collaborator who understands the high unmet medical need, clear clinical benefit and importance of timely patient access,” said Gaurav Shah, M.D., Chief Executive Officer, Rocket Pharma. “CBER leadership’s direct involvement and commitment to working expeditiously to deliver this therapy to patients gives us great hope on behalf of the primary immunodeficiency community.”
Positive top-line data from the global Phase 1/2 study of KRESLADI™ demonstrated
About KRESLADI™ (marnetegragene autotemcel; marne-cel)
KRESLADI™ is an investigational gene therapy that contains autologous (patient-derived) hematopoietic stem cells that have been genetically modified with a lentiviral (LV) vector to deliver a functional copy of the ITGB2 gene, which encodes for the beta-2 integrin component CD18, a key protein that facilitates leukocyte adhesion and enables their extravasation from blood vessels to fight infection.
Rocket holds FDA Regenerative Medicine Advanced Therapy (RMAT), Rare Pediatric, and Fast Track designations in the
About Leukocyte Adhesion Deficiency-I
Severe Leukocyte Adhesion Deficiency-I (LAD-I) is a rare, autosomal recessive pediatric disease caused by mutations in the ITGB2 gene encoding for the beta-2 integrin component CD18. CD18 is a key protein that facilitates leukocyte adhesion and extravasation from blood vessels to combat infections. As a result, children with severe LAD-I are often affected immediately after birth. During infancy, they suffer from recurrent life-threatening bacterial and fungal infections that respond poorly to antibiotics and require frequent hospitalizations. Children who survive infancy experience recurrent severe infections including pneumonia, gingival ulcers, necrotic skin ulcers, and septicemia. Without a successful bone marrow transplant, survival beyond childhood is rare. LAD-I is estimated to impact an estimated 800 to 1,000 individuals in the
