New York City, 14 Jan 2019: Gene therapy continues to advance with
several programs demonstrating proof of concept and well positioned to be
competitive products. Current clinical development of gene therapy is
predominantly centered on hereditary diseases, for which repeated drug
administration could be burdensome for patients.
The approval of Luxturna, developed by
Spark Therapeutics for inherited retinal disease is a watershed event facing
this space. Luxturna gained the U.S. FDA approval in December 2017 and is priced
at a whopping USD 850,000. Gene therapy market in late 2017 also witnessed the
approvals of Gilead/Kite Pharma’s Yescarta and Novartis’ Kymriah in the cancer
therapeutic area.

In addition, the commercialization of
BMN270, hemophilia A treatment, in Phase III clinical trials, developed by
BioMarin and Lenti-D by bluebird bio, gene therapy for childhood cerebral
adrenoleukodystrophy (CCALD), in Phase III clinical trials, are gaining
visibilities, implying that gene therapy will be used to treat a wider range of
diseases. After some minor setbacks, bluebird’s LentiGlobin appears poised to
deliver strong clinical results in beta-Thalassemia and potentially for sickle
cell patients as well. Renova Therapeutics’ lead product candidate RT-100
entered Phase III trials early this year for congestive heart failure, the
first gene therapy product that has advanced to late-stage trials in a
cardiovascular indication. The FDA has fast tracked RT-100 AC6 gene transfer
therapy for treatment of patients with heart failure with reduced ejection
fraction (HFrEF). RT-100 fulfills significant clinical unmet need in the CHF
patient population while serving an addressable market opportunity of over USD 3 billion.
There are a number of frontier companies
emerging as important players in the field. AveXis’ AVXS-101 for Spinal
Muscular Atrophy (SMA) is the highest-visibility gene therapy program, and
continues to rapidly advance with potential for early approval. Similarly, Gene
therapy for Parkinson’s by Voyager Therapeutics is demonstrating clinical
benefit in a 5-patient mid-dose cohort and Hemophilia by UniQure and Spark
Therapeutics continues to be an area of focus for the field.
Setting aside some setbacks and
disappointments, the number of patients treated successfully and safely with
gene therapy continues to grow and the consistent clinical evidence points to a
robust platform with utility in both Orphan and ultra-Orphan diseases and
broader indications.
Large Pharmaceuticals and Biotechnology
companies’ exhibit strong interest in this field and notable among them include
Allergan, Shire, Biomarin, Pfizer and GSK. In particular, GSK has a meaningful
presence in gene therapy with the approved Strimvelis for ADASCID in Europe and
a deep pipeline of programs. Moreover, this space is abuzz with a wave of
partnerships and alliances. Pfizer has recently expanded its presence in gene
therapy with the acquisition of Bamboo Therapeutics and Allergan entered the field,
with the acquisition of RetroSense and its Phase I/II optogenetic program.

Gene Therapy represents the leading edge of
Biotechnology’s promise to change disease paradigms. Although gene therapy
space is still in its infancy, the field continues to offer promise. About
$12bn investment is riding on a growing universe of small cap public gene
therapy companies. The evidence of success in Spinal Muscular Atrophy,
Hemophilia A & B, sickle cell disease & beta thalassemia and a rare
genetic cause of blindness have ignited investor interest in the field and
expanded the number of clinical and preclinical development programs all
targeting a large addressable market and serving strong unmet need.
