With a few tweaks to the protocol, Rocket Pharmaceuticals Inc.’s phase II trial testing RP-A501 in Danon disease is expected to resume following the lifting of the clinical hold, issued by the U.S. FDA in May in response to the death of a patient in the pivotal gene therapy study.
The U.S. FDA has cleared Rocket Pharmaceuticals Inc.’s IND application for RP-A701, an AAVrh.74-based gene therapy candidate for the treatment of BAG3-associated dilated cardiomyopathy (BAG3-DCM), a severe form of heart failure.
Rocket Pharmaceuticals Inc. CEO Gaurav Shah said his firm is investigating how its gene therapy for Danon disease may have created an “unexpected and paradoxical” effect that led to problems for a phase II patient who ultimately died.
Two days before the PDUFA date, the U.S. FDA handed down a complete response letter (CRL) for Rocket Pharmaceuticals Inc.’s Kresladi (marnetegragene autotemcel), delaying potential approval of the lentiviral-based gene therapy as the first therapeutic option for leukocyte adhesion deficiency type I, a rare, inherited immune disorder. But the Cranbury, N.J.-based company has suggested that delay won’t be long, as the CRL requests only “limited” chemistry manufacturing and controls (CMC) information – additional CMC data were also cited as the reason for the three-month review extension earlier this year.
The combination of new U.S. FDA phase II study guidance and a $175 million underwritten public offering sent gene therapy developer Rocket Pharmaceuticals Inc.’s stock soaring on Sept 13. Shares (NASADQ:RCKT) closed 38.8% upward to $21.23 each on Sept. 13.
Arrhythmogenic cardiomyopathy (ACM) is a devastating inherited disorder characterized by massive cardiomyocyte loss, fibrofatty infiltration and ventricular arrhythmias, among others. Most known genetic causes of ACM involve the gene PKP2, which encodes plakophilin-2. An unmet medical need exists regarding therapies that correct this PKP2 deficiency.
Rocket Pharmaceuticals Inc. has received IND clearance from the FDA for RP-A601, an AAV.rh74-based gene therapy candidate for the treatment of arrhythmogenic cardiomyopathy due to plakophilin 2 pathogenic variants (PKP2-ACM). RP-A601 offers the potential for a one-time, curative alternative to medical therapy, implantable cardioverter defibrillators and ablations.
Rocket Pharmaceuticals Inc. has added RP-A601 to its cardiac gene therapy portfolio for the treatment of arrhythmogenic cardiomyopathy due to plakophilin 2 pathogenic variants (PKP2-ACM).
Shares of Renovacor Inc. (NYSE:RCOR) closed at $2.18, up 28 cents, or 14.7%, on word that Rocket Pharmaceuticals Inc. is acquiring the firm in an all-stock transaction valued at $53 million. Rocket, of Cranbury, N.J., said “compelling” preclinical data generated by Cambridge, Mass.-based Renovacor validates an AAV-based transgene replacement strategy for BLC2 athanogene 3 dilated cardiomyopathy.
Cambridge, Mass.-based Agios Therapeutics Inc.’s encouraging phase III data from a pair of trials with allosteric activator mitapivat in pyruvate kinase deficiency brought more attention to the space, where Rocket Pharmaceuticals Inc. – at a much earlier stage – is trying a gene therapy called RP-L301.
