PIPELINE

Our Pipeline consists of drugs for chronic neurodegeneration - Alzheimer’s disease (AD), its orphan indication Alzheimer’s disease and dementia in Down syndrome (AD-DS) and Parkinson’s disease (PD). Additionally, we have a compound to treat acute neurodegeneration - traumatic brain injury (TBI) and stroke - and a third compound for advanced AD.

ANVS401 is our lead compound. It is being developed for AD, AD-DS and PD, because in preclinical studies it improved axonal transport in these diseases by inhibiting the neurotoxic proteins that kill nerve cells. It was shown in human and animal studies to lower APP/Aβ, tau/phospho-tau and α-synuclein, the neurotoxic proteins that impair axonal transport and lead to inflammation and cell death. The compound was tested in three Phase 1 clinical studies that show it to be well tolerated [Investigator Brochure 2015]. This safety data is applicable to the clinical development of ANVS401 for AD-DS, AD, PD and other chronic neurodegenerative disorders.

ANVS405 is being developed for acute indications, focused on protecting the brain after TBI and/or stroke. ANVS405 is the same compound as ANVS401, but it is given intravenously in cases of acute head and brain trauma. ANVS405 was given to rats as an injectable after TBI to ensure that it would reach the brain quickly. TBI rats that were treated after the insult exhibited enhanced memory and learning and lowered microglia activation, a measure of inflammation. To date the development of ANVS405 has been funded by the US Army and we plan to further apply for grants to continue the development.

ANVS301 is expected to increase cognitive capability in later stages of AD and dementia. In preclinical studies, ANVS301 improved memory and learning in very old rats. ANVS301 is in a Phase 1 clinical trial that is being conducted and financed by the National Institutes of Health (NIH).

 

ANIMAL AND HUMAN STUDIES

ANVS401 REDUCES THE LEVELS OF NEUROTOXIC PROTEINS TO LEVELS FOUND IN HEALTHY VOLUNTEERS

Neurotoxic proteins measured in the CSF of MCI patients in the POC study described above. ANVS401 given for 10 days did not just lower APP and Tau but reduced their levels close to the average levels measured in healthy volunteers.

ONGOING STUDIES

Ongoing Annovis Phase 2a Study in AD Patients

We are presently conducting a study in early AD patients. We are treating patients for 4 weeks with ANVS401 and measure target and pathway engagement in the spinal fluid. This means that we are measuring levels of neurotoxic proteins, neurotransmitters, neurotrophic factors, inflammation and nerve cell death as well of cognitive improvement.

 

 

Planned Annovis Phase 2a Study in PD Patients
 

We are planning to start an equivalent Phase 2a study in early PD patients, in which we will also be measuring levels of neurotoxic proteins, neurotransmitters, neurotrophic factors, inflammation and nerve cell death as well of cognitive improvement.

Both studies:

  • Are multi-center, randomized, double-blind, placebo-controlled trials

  • Enroll, or will enroll, subjects diagnosed with early AD or early PD, respectively

  • Will measure target and pathway engagement

  • Will potentially show efficacy

  • Will provide optimal information to proceed to pivotal studies, in AD-DS and PD, respectively, with large scale cognitive endpoints

The successful outcome of both studies will validate ANVS401s inhibition of the toxic cascade that leads to neurodegeneration in AD and PD; it will give us some indications of efficacy; it will and allow the company to move into two Phase 3 studies, one in AD-DS, an orphan indication of AD, and one in PD.
