Data released May 9 by the Alliance for Regenerative Medicine (ARM) illustrates the growth of clinical activity where gene therapy is concerned.
ARM’s Quarterly Regenerative Medicine Global Data Report for the first quarter of 2019 showed 372 gene therapy clinical trials were in progress as of the end of Q1. Interestingly, a majority (217 or 58%) were studies in Phase II, followed by Phase I (123 or 33%), and Phase III (32 or 9%).
The number of gene therapy clinical trials inched up by 10 from the 362 recorded as of the end of 2018. More significantly, the number of clinical studies jumped 17% year-over-year from the 319 trials in progress as of the first three months of 2018.
Also heating up is the pace of gene therapy activity outside of trials. On April 15, Catalent signaled its intent to expand into gene therapy when it said it had agreed to acquire Paragon Bioservices for $1.2 billion. Thermo Fisher Scientific will expand its capabilities in the field once it completes its planned $1.7 billion purchase of viral vector CDMO Brammer Bio, planned for the end of the second quarter.
The year’s biggest gene therapy M&A deal to date came in February, when Roche said it planned to acquire Spark Therapeutics for $4.8 billion. However, resistance from Spark shareholders seeking a higher price has compelled Roche to extend its tender-offer deadline twice; the offer is set to expire on June 3.
As for approvals of new gene therapies, two candidates considered close to approvals appear on this list. One is Zynteglo™ (formerly LentiGlobin™), a bluebird bio gene therapy for thalassemia and sickle cell disease that has received a positive recommendation for approval by the European Medicines Agency’s Committee for Human Medicinal Products—a usually-reliable indicator of final approval by the European Commission.
The other candidate in the homestretch of regulatory review is Zolgensma® (formerly AVXS-101) from AveXis, a Novartis Company. Zolgensma is a spinal muscular atrophy gene therapy that has won more news coverage for its planned multi-million-dollar price tag than for its positive Phase III trial data.
Zynteglo and Zolgensma are joined by 23 other “up-and-coming” gene-therapy candidates that have reached Phase III and/or registrational trials as of the first quarter of 2019, based on figures from ARM, as well as ClinicalTrials.gov and/or company announcements. As with last year’s A-List, each candidate is listed by name, sponsor(s), indication(s), mechanism, late-stage trials, and updates.
Two gene therapy candidates on ARM’s list are not included. One is CMB305, a prime-boost cancer vaccine designed to target tumors that express NY-ESO-1. Immune Design halted a Phase III combination trial with Roche/Genentech’s Tecentriq® (atezolizumab) after disappointing Phase II results in synovial sarcoma. At the time, Immune Design said it would seek an external development partner for CMB305. Instead, the company was acquired by Merck & Co. for approximately $300 million, a deal completed April 2.
Also not included below is Amgen’s Imlygic® (talimogene laherparepvec). It was initially approved in 2015, and is now in trials for additional melanoma indications (NCT02263508 and NCT02211131).
Among promising candidates that bear watching is Audentes Therapeutics’ AT132, an X-linked myotubular myopathy candidate. Audentes plans third-quarter talks with the FDA and EMA on license application submission pathways following positive Phase I/II data—most recently on May 1, when the company announced “significant and sustained” improvements in neuromuscular function in both dose cohorts.
Another promising candidate, Avrobio’s AVR-RD-01 for Fabry disease, said April 29 it will move ahead with its Phase II FAB-201 trial (NCT03454893) and dosing of patients at U.S. clinical sites, following IND clearance from the FDA.

Ferring last year acquired an option for global commercialization rights to Instiladrin.
Lenti-D
Sponsor(s): bluebird bio
Indication(s): Cerebral adrenoleukodystrophy (CALD)

Updates: Eyevance licensed worldwide rights to Nexagon from OcuNexus in October 2018 for an undisclosed price, saying it was funding a pivotal trial anticipated to start this year. The Phase IIb study would assess Nexagon as a potential treatment for PED caused by thermal or chemical burns, Eyevance CSO Mark Jasek, PhD, said on a video posted on YouTube November 5, 2018, by the organizer of the Ophthalmology Innovation Summit.
NSR-REP1

Zolgensma® (formerly AVXS-101)
Sponsor(s): AveXis, a Novartis company
Indication(s): Spinal muscular atrophy (SMA)
Mechanism: A nonreplicating adeno-associated virus 9 (AAV9) capsid is used to deliver a functional copy of a human SMN gene to the nucleus of the patient’s own cells. The gene is meant to supplement the cell’s production of the SMN protein, increasing that production to an adequate level.
