e are a clinical stage biopharmaceutical company pioneering immuno-neurology, a novel therapeutic approach for the treatment of neurodegeneration. Immuno-neurology targets immune dysfunction as a root cause of multiple pathologies that are drivers of degenerative brain disorders. We are developing therapies designed to simultaneously counteract these pathologies by restoring healthy immune function to the brain. Supporting our scientific approach, our Discovery Platform enables us to advance a broad portfolio of product candidates, validated by human genetics, which we believe will improve the probability of technical success over shorter development timelines.

As a result, in the last five years, we have identified over forty immune system targets, progressed over ten programs into preclinical research, and advanced two product candidates, AL001 and AL002, into clinical development. In the second half of 2018, AL001, initially aimed at treating FTD-GRN patients, was dosed in forty-two healthy subjects in a single ascending dose Phase 1 study. There were no serious adverse events or dose limiting adverse events reported in the study, achieving the primary endpoint.

Our Discovery Platform leverages large scale human genetic datasets, advanced tools in bioinformatics and imaging, and insights into neurodegeneration and immunology to identify immune system targets that play a critical role in the development of multiple neurodegenerative diseases. Our Discovery Platform focuses on:

 • Target Selection. We identify mutations in genes that control the brain’s immune system, which we believe are the root cause of neurodegeneration, employ a suite of genetic tools to elucidate the immune dysfunction caused by these mutations, and then engineer immune modulating antibodies to counteract the harmful consequences of these genetic mutations.

 • Biomarker Selection. We are able to identify and employ molecular biomarkers, assays, and precise imaging techniques to confirm target engagement and measure the effect of our product candidates, allowing us to potentially obtain clinical data earlier than would otherwise be expected using traditional clinical measures.

 • Patient Selection. We utilize genetic screening and other biomarkers to better align a patient’s specific diagnosis with the targeted intervention in each of our clinical studies.
