We are so happy to have these world renowned macular degeneration experts join the Aviceda family developing a drug that resolves overactivated chronic innate immune phagocytic retinal inflammation, the underlying cause of geographic atrophy, in patients with advanced dry AMD.
The potential to repolarize inflammatory Microglia with AVD 104 to the neuroprotective subretinal microglial state identified by the Saban lab at Duke https://hubs.la/Q02j8cMC0 has the potential not only to halt progression of GA but rescue photoreceptors and RPE cells that have not already undergone irreversible apoptosis. The ability to rescue retinal cell and photoreceptor function was seen in a single intravitreal injection dose escalation trial of AVD 104 in patients with center involving bilateral GA patients.(SIGLEC part 1 trial)
These patients had a dose dependent significant improvement in ETDRS BCVA which corroborated with multi focal ERG improvement and anatomic cessation of RPE cell loss over a follow up of 3 months . This degree of clinical efficacy resulting from AVD 104 have never been seen with any investigational drug tested or approved for GA and hold the promise of not only preventing vision loss but recovering visual function.
AVD104 also represents a novel class of self associated molecular pattern mimetic designed to bind to Sialic acid Ig like lectin (SIGLEC ) family of receptors the most abundant checkpoint receptors in the immune system , which utilizes the ITIM/ITSM checkpoint pathway of PD1 (keytruda target) and which represents the main self receptor, the main pathway to prevent autoimmunity and a pathway used by cancers and infections to evade immune detection.
In addition AVD 104 binds CFH as the requisite activator of the decay accelerating function of CFH. By physiologically abrogating the alternative pathway, the maintenance homeostatic role of complement can be restored versus disabled by current complement inhibitory strategies.
Aviceda uses the immune systems natural immune controls to reign in age accelerated immune activation. Without these key clinical advisors, this promising novel therapy to treat the devastating condition of GA would never be realized. So please join me in welcoming theses critical advisors to the Aviceda journey.

4moAlso, advancements in NASH treatment include promising candidates like pegozafermin from 89bio, showing potential as a best-in-class option for non-alcoholic steatohepatitis (NASH). Additionally, Altimmune, Inc. has made significant progress with their treatments. These developments represent a forward leap in managing MASH effectively. Madrigal Pharmaceuticals' Resmetirom (Rezdiffra), the first and only approved MASH therapy, will definitely change the competitive landscape.
