Implications of non-coding RNA on Cystic Fibrosis: new therapeutic avenues

Editorial

Paul J McKiernan and Catherine M Greene

Catherine Greene HeadshotPaul Headshot

Although cystic fibrosis (CF) occurs due to a recessive mutation in a single gene, gene therapy to correct this defect has remained unrewarding. In fact, until recently the scientific and medical community has only been able to treat the varying symptoms of the disease; but recent advances offer much hope for the treatment of the underlying genetic defect. CF predominates in Caucasians compared to other races and Ireland has the highest carrier rate in the world (1 in 19) and a CF prevalence of 2.98 per 10,000 live births. This is four times higher than that of the USA or the European Union (EU) average, where the cost of CF healthcare approximates to €0.6 billion per annum [1,2]. While advances in recent years have improved treatment and lengthened the median survival of people with CF, there is still no effective cure.

Cell & Gene Therapy Commercial Insight – May 2016

Alan Boyd & Mark Curtis

Providing a critical overview of the sector’s commercial developments – M&As, licensing agreements & collaborations, financial results, IPOs and clinical/regulatory updates, with commentary from our Expert Contributors.

CELL THERAPY:

Investors looking for an opportunity to gain exposure to gene editing technologies on the public markets were given their second opportunity this past month after Intellia Therapeutics closed its initial public offering raising net proceeds of just under $113 million. One of its close competitors, Editas Medicine, went public only months ago raising $94 million to list on the NASDAQ. Gene editing technologies can be applied as in vivo gene therapies, or be leveraged ex vivo to produce cell-based gene therapies. While these cutting edge technologies offer fundamentally game changing advances to the field, investing in their equities comes with the challenge of volatility following go-public transactions. Like many of the cell-based immunotherapy companies that went public in 2015, Editas’ massive gains post-IPO were followed by a crash in stock price. For investors that have the risk tolerance appropriate for early-stage platform technologies poised to enter the clinic, Editas and Intellia are buy and hold for the long-term. What is yet to be determined is who will win the ongoing patent battle over CRISPR/Cas9 claims, which will be a future twist that adds further volatility to the system.

GENE THERAPY:

The announcement between Biogen and U. Penn is yet another example of Big Pharma discovering the value of taking cell and gene therapy products seriously. They were there at the dawn of gene therapy development and then got ‘cold feet’ and avoided the area, particularly after the death of Jesse Gelsinger. However now that most of the hard work has been done by small companies and academic groups and as some of these products have come closer to market, ‘Big Pharma’ has come back in – well…better late than never!

Review

Holoclar: first of its kind in more ways than one

Review

Giovanni Milazzo, Diego Ardigò, Marta Toschi, Stanislav Matuska, Paolo Rama, Michele De Luca & Graziella Pellegrini

This article describes the regulatory pathway that enabled the translation of academic research and clinical experience of an ex-vivo expanded autologous stem cell-based treatment for limbal stem cell deficiency (LSCD) into a pharmaceutical product compliant with the European Union regulations of Advanced Therapy Medicinal Products (ATMP). Holoclar® was originally developed in Italy as a surgical procedure and used in more than 200 patients. Following the establishment of the EU ATMP Regulation EC 1394/2007, Holoclar development required that manufacturing was as per current Good Manufacturing Practice requirements and collection of retrospective clinical data was ICH-E6 and E3 compliant. Holoclar is an ex-vivo expanded autologous human corneal epithelial cells containing stem cells and is classified as “tissue engineered product”. Based on the evidence of quality and control of the manufacturing process, safety, efficacy and on a positive benefit–risk balance in 104 patients (72.1%) of 148 patients treated, Holoclar received conditional Marketing Approval in the EU. Holoclar is the first medicine approved in the EU for this rare eye condition that can result in blindness.

An Industry Perspective on the Clinical Preparation of Cell Therapies

Spotlight Article

EXPERT INSIGHT

INTEGRATION OF MANUFACTURING & DELIVERY INTO HEALTHCARE

Brian Murphy

Cell therapies are a promising class of biologics which exhibit many capabilities not available to other pharmaceuticals. Cells can respond to their environment in a conditional and multifunctional manner, and in some cases can home to specific regions or proliferate within the patient. These unique properties enable new therapeutic approaches to treat patients’ unmet medical needs. However, there are also new challenges that extend all the way to the patient’s bedside. With a medicinal product that is alive, the delivery and administration procedures must be designed and controlled to ensure cellular health, while also managing the complexity and biological limitations of specific cell types. As a practical matter, solutions must align with existing medical infrastructure to get viable drug products to the patient populations who need it. From an industry perspective, the goals around clinical preparation and administration are to provide a safe and effective therapy in a standardized manner that is operationally efficient and robust.

Cell & gene therapies and the evolving role of personalized medicine

spotlight-header

Damian Marshall, Michaela Sharpe & Stephen J Ward

EXPERT INSIGHT

Personalized medicine is an innovative approach to disease prevention and treatment that takes into account differences in how individuals respond to medication. Advances in personalized medicine have already led to powerful new discoveries and approved treatments that are tailored to specific characteristics of individuals, such as a person’s genetic makeup, or the genetic profile of an individual’s tumor. Autologous cell therapies are arguably one of the most personalized forms of medicine, using a patient’s own cells to generate a bespoke product that is only administered back to the original donor. This article discusses the emerging role of personalized medicine in various cell and gene therapies, its role in health economics and challenges to its implementation.

Research Article

Objective: Bone marrow cell therapy has pioneered the field of regenerative medicine for the treatment of ischemic disease, but remains a controversial topic due to persistent uncertainty on purity and quality of the cell product. Here, we evaluated the therapeutic activity of pro-angiogenic clones derived from single-sorted long-term repopulating hematopoietic stem cells (LT-HSCs, CD150+/CD34/Lineage-/Sca-1+/c-Kit+) in a murine model of hindlimb ischemia. Approach and Results: C57BL/6 mice underwent unilateral limb ischemia by femoral artery occlusion, followed by intramuscular injection of green fluorescent BM LT-HSCs cells (2,000 per mouse) from congenic donor C57BL/6-Tg(CAG-EGFP)131Osb/LeySopJ mice or vehicle (PBS). Cell therapy with LT-HSCs markedly accelerated the recovery of blood flow to the ischemic limb as measured by laser Doppler flowmetry (P2, P<0.05) and arteriole density (108 ±6 vs. 72 ±9/mm2, P<0.05). Additionally, LT-HSC therapy improved the viability and proliferation of resident vascular cells. In separate experiments, single sorted BM LT-HSC-derived cells were expanded up to 40,000 fold in culture giving rise to two distinct clone subsets, according to the expression level of the surface marker CD31. Upon transplantation in the mouse ischemic model, CD31high LT-HSC-derived cells showed superior pro-angiogenic and pro-healing activities as compared with CD31low LT-HSC-derived cells. Conclusions: These data establish clonogenic CD31high LT-HSC-derived cells as a promising cell therapy approach for the treatment of limb ischemia.
