About Biohaven

Biohaven is a privately-held biopharmaceutical company engaged in the identification and development of clinical stage compounds targeting the glutamatergic system. The company has licensed intellectual property from Yale University and Massachusetts General Hospital. The company's first drug candidate, BHV-0223, is a unique formulation of riluzole, a glutamate modulating agent, that utilizes the Zydis® ODT fast-dissolve technology under an exclusive worldwide agreement with Catalent. Agents that modulate glutamate neurotransmission may have therapeutic potential in multiple disease states involving glutamate dysfunction, including ALS, Alzheimer's disease, Rett syndrome, dementia, dystonia, tinnitus, anxiety disorders, and affective disorders like major depressive disorder.

Relevant updates in the progress of their programs include:

a.

A Phase 1/2a study designed to assess the safety, tolerability, and pharmacokinetics of single and multiple doses of BHV0223 in healthy volunteers. Data from this trial will be used to design Phase 2/3 studies in subjects who suffer from anxiety disorders.

b.

Receipt of favorable and productive feedback from their Pre-Investigational New Drug Application (PIND) interaction with the Food and Drug Administration ("FDA") pertaining to their  investigative product, BHV-0223, and the intended initial registrational program under 505(b)2 pathway for the indication of amyotrophic lateral sclerosis ("ALS"). No issues were identified in the FDA response that would impede Biohaven's planned bioequivalence trial in 2016.

c.

Recently, FDA has granted Biohaven's orphan drug designation request covering BHV-0223 for the treatment of spinocerebellar ataxia.

Biohaven plans to advance other glutamatergic approaches and is actively exploring licenses for additional compounds.

About Portage:

Portage is engaged in identifying, financing and developing novel therapeutics in indications with high unmet medical need. Portage plans to add 5-7 other opportunities to its portfolio either by direct investment into a company, spinout from academia, or through the creation of an SPV with another company or management team

Apart from Biohaven, Portage also has fully owned subsidiary, Portage Pharmaceuticals Limited (PPL). PPL has successfully validated a new proprietary cell permeable peptide platform technology that has been shown to efficiently deliver an active pharmacological agent or cargo into a cell without disrupting the cell membrane. PPL will be advancing its lead candidate, PPL-003, to an Investigational New Drug (IND) application for the topical treatment of dry eye disease and uveitis.  PPL recently completed a study in a rat model of dry eye disease in which a topical PPL-003 solution achieved highly significant efficacy and a more rapid onset of action than topical 0.1% dexamethasone.

Portage has also invested in Sentien Biotechnologies Inc., a Boston based private company developing an extracorporeal bioreactor for the delivery of cell therapies. This summer, Sentien completed a financing that will allow it to finish IND enabling studies and a Phase I trial.
