Overview
We are a genetic medicines company dedicated to transforming the lives of patients suffering from rare genetic diseases with significant unmet medical needs by curing the underlying cause of the disease. Our proprietary platform is designed to utilize our human hematopoietic stem-cell derived adeno-associated virus vectors, or AAVHSCs, to precisely and efficiently deliver single administration genetic medicines in vivo either through a gene therapy or nuclease-free gene editing modality across a broad range of genetic disorders. The unique properties of our proprietary suite of 15 novel AAVHSCs enable us to focus on a method of gene editing called gene correction, either through the replacement of an entire diseased gene in the genome with a whole functional copy or the precise repair of individual mutated nucleotides, by harnessing the naturally occurring DNA repair process of homologous recombination, or HR. We believe our HR-driven gene editing approach will allow us to efficiently perform gene correction at therapeutic levels without unwanted on- and off-target modifications, and to directly measure and confirm those modifications in an unbiased manner to ensure only the intended changes are made. By utilizing the body’s natural mechanism of correcting gene defects, we also avoid the need for exogenous nucleases, or bacteria-derived enzymes used in other gene editing approaches to cut DNA, that are known to significantly increase the risk of unwanted modifications. Our diverse set of AAVHSCs allows us to precisely target, via a single injection, a wide range of disease-relevant tissues, including the liver, central nervous system, or CNS, bone marrow, lung, muscle and eye, across both modalities—gene editing and gene therapy. We believe these advantages will allow us to safely provide transformative cures using either modality.
We have generated compelling preclinical data for our first and lead product candidate, HMI-102, a gene therapy for the treatment of phenylketonuria, or PKU, and expect to advance HMI-102 into a Phase 1/2 clinical trial in adult PKU patients and report initial clinical data in 2019. We continue to advance our gene editing modality and have generated in vivo preclinical data demonstrating achievement of gene correction efficiencies in the liver that are significantly greater than both nuclease-based and other adeno-associated virus, or AAV, based approaches and are at a therapeutic level. We have nominated a lead gene editing product development candidate, HMI-103, for the treatment of PKU in pediatric patients. We have also nominated a lead gene therapy CNS product development candidate, HMI-202, for the treatment of metachromatic leukodystrophy, or MLD. We have initiated IND-enabling studies for both programs.
Our management team has a successful track record of discovering, developing and commercializing therapeutics with a particular focus on rare diseases. Our genetic medicines platform is based on gene editing and gene therapy technologies resulting from the pioneering work conducted on AAVHSCs in the laboratory of the City of Hope Medical Center in California, or COH. We have a robust intellectual property portfolio with issued composition of matter patents in the United States for our suite of 15 AAVHSCs and we believe the breadth and depth of our intellectual property is a strategic asset that has the potential to provide us with a significant competitive advantage. We continue to build on our intellectual property estate through our ongoing product and platform development efforts. We have internal process development and Good Manufacturing Practices, or GMP, manufacturing capabilities and recently completed the build-out of a current GMP, or cGMP, manufacturing facility to support our clinical development programs in both gene therapy and gene editing and expect to commence manufacturing in the first half of 2019. In November 2017, we entered into a collaboration with Novartis Institutes for Biomedical Research, Inc., or Novartis, to develop new genetic medicines using our HR-based gene correction approach in ophthalmology, which leverages our platform technology into a new therapeutic area, as well as other exploratory areas.
Since our inception in 2015, we have raised approximately $288 million in net proceeds through our initial public offering, or IPO, in April 2018 and preferred stock financings. We will require additional capital in order to advance HMI-102 and our other product candidates through clinical development and commercialization. We believe that our compelling preclinical data, scientific expertise, product development strategy, manufacturing capabilities, and robust intellectual property position us as a leader in the development of genetic medicines.
Our Opportunity in Genetic Medicines
We are currently focused on monogenic diseases where the genetic abnormality is known to occur in a single diseased gene. The majority of monogenic diseases harbor thousands of individual mutations within the diseased gene, each resulting in a loss of function. Replacing an entire diseased gene with a whole functional gene is the optimal therapeutic approach for addressing these monogenic disorders. This can be accomplished either through a method of gene therapy called gene transfer in slowly or non-dividing cells, or through a method of gene editing called gene correction in rapidly dividing cells.
The current focus of most nuclease-based gene editing methods is gene knockout, or knocking out a diseased gene to prevent the expression of an undesired protein. Since gene knockout does not result in a fully-corrected gene, this method can only potentially address the minority of monogenic diseases where a diseased protein requires knock-down or inactivation. In addition to our knockout capabilities, our HR-driven gene correction method allows us to achieve integration into the patient’s genome and potentially address the significant majority of monogenic diseases by replacing an entire diseased gene with a whole functional gene or repairing a single mutation to fully correct the defect. Gene therapy, on the other hand, seeks to introduce a functional copy of a defective gene or gene sequence into a patient’s own cells, but not incorporate such copy into the patient’s genome. This method, called gene transfer, results in the expression of the therapeutic protein of interest without changing the genome.
DNA Repair Pathways
Human cells harbor two primary independent pathways to maintain the integrity of DNA: homologous recombination, or HR, and non-homologous end joining, or NHEJ, which are described below:
|
|
• |
HR is a process in which cells repair DNA through highly precise incorporation of correct DNA sequences that are homologous, or matching, to the site of damage. HR has evolved to repair DNA with high fidelity and avoids the introduction of unwanted mutations at the site of correction. In the late 1990’s, researchers discovered that certain adeno-associated virus, or AAV, vectors deliver gene sequences into the genome specifically through the HR process. These AAV vectors delivered long single strands of homologous DNA to specific regions in the genome and induced the HR pathway, but their low efficiency of approximately 1% limited their use as a viable option for in vivo therapeutics. |
