PureTech’s milk exosome-based technology is uniquely designed to facilitate the oral administration of complex payloads such as nucleic acids, peptides, and small molecules. These exosomes are believed to traffic via lymphatic circulation and could potentially enable the targeting of immune cells in novel ways.

Daphne Zohar, Co-founder and Chief Executive Officer of PureTech Health, said: "We are excited to accelerate the development of this promising technology from our internal lymphatic and immune cell trafficking programmes. The expertise and resources that Roche is bringing to the collaboration will help us to potentially address one of the biggest challenges in oligonucleotide-based therapeutic development: oral administration of nucleic acids."

PureTech Health has been advancing internal research and development projects that focus on the Brain-Immune-Gut (BIG) Axis, with an emphasis on lymphatics and immune cell trafficking to modulate immunity in a tissue-specific manner. These internal pipeline programmes are being consolidated into a separate division of PureTech Health called Ariya. PureTech’s Internal division, which includes the milk-derived exosome technology, has generated compelling pre-clinical data and secured key intellectual property for its lymphatic and immune cell trafficking programmes.

About PureTech’s Milk Exosomes Technology

Milk exosomes represent a significant opportunity to potentially resolve the long-standing challenge of oral bioavailability of macromolecules and complex small molecules. Exosomes, which contain mixtures of lipids, proteins and nucleic acids, play a critical physiologic role in intercellular communication and the transport of macromolecules between cells and tissues. Mammalian-derived exosomes have attractive potential as vehicles for the administration of a variety of drug payloads, especially nucleic acids, since their natural composition will likely provide superior tolerability over the variety of synthetic polymers currently in use. Most sources of mammalian exosomes are not suitable or viable as vehicles for oral administration of drugs due to their lack of stability under the harsh physiologic conditions associated with transit through the stomach and small intestine; however, the milk-derived exosomes that form the basis for PureTech’s internally-developed technology have evolved naturally and specifically to accomplish the task of oral transport of complex biological molecules. The technology is based on research conducted by PureTech Health and its academic collaborators, including Ramesh Gupta, PhD, Agnes Brown Duggan Chair in Oncological Research at the James Graham Brown Cancer Center, and Professor in the Department of Pharmacology and Toxicology at University of Louisville, and exclusively licensed to PureTech Health.

Targeting the CD47-SIRPα axis is emerging as one of the most promising new cancer immunotherapy approaches seeking to target the innate immune response. A recent analysis reveals just how intense the global interest is and a growing list of stakeholders operating in this field.

Highest Stage Breakdown of CD47/SIRPα Molecules

Most of the identified molecules are either anti-CD47 antibodies or SIRPα-Fc recombinant proteins. In healthy cells, CD47 serves as a “don’t eat me” signal by binding to the transmembrane SIRPα protein on phagocytic cells, preventing the engulfment of “self” by macrophages. In several cancer types, tumor cells overexpress CD47 to elude the immune system. Exploration of this property has been the driving force to attract hundreds of million of dollars in investments to companies like Tioma Therapeutics (now Arch Oncology), Surface Oncology and Forty Seven, the latter of which has just recently completed a $100M+ IPO. Deals in this area include the early adopter move in 2012 by Celgene securing Inhibrx’ anti-CD47 antibody in a $500 million dollar deal to the recent billion dollar plus agreement between OSE Immunotherapeutics and Boehringer Ingelheim.

On the patent front, it is evident that that the Synthon/Sanquin Blood Supply intellectual property rights hold some clout in the CD47 world following Forty Seven’s $47 million settlement and license agreement with Synthon. The license agreement also includes some far reaching concessions by Forty Seven in order for them to obtain freedom to operate. Moreover a recent patent analysis accessible in this product shows several new CD47/SIRPA bispecific/fusion-proteins, CD47 mimetics and additional, previously unknown, combination therapy strategies set forth along with methods for determining responsiveness to anti-cd47 agent

CD47/SIRPα Molecules Are In Development in Thirty Five Different Tumor Types

On the clinical development front, this report identifies fewer than ten molecules targeting the CD47-SIRPα axis which have made it into the clinic. So far with encouraging results, following the early termination of a Phase I/II trial of Tioma’s Ti-061 in late 2017.

Several of these trials also shed light on biomarker- and combination therapies of interest. On the horizon, this field will soon have another injection of candidate therapies with bispecific CD47 antibodies entering the clinic in late 2018 or early 2019.

The CD47/SIRPα Molecules Are Also Targeting Thirteen Other Targets, Including Bispecific Antibodies

Moreover, targeting the CD47-SIRPα axis also has the potential to become the combination therapy of choice as has already been demonstrated via mediating longer survival in mice together with oncolytic virotherapy and enhancing phagocytic capacity when used together with Carisma Therapeutics’ CAR macrophages. Carisma Therapeutics themselves have just announced a $53 million series A round of financing in order to develop its novel CAR macrophage cellular immunotherapy and is estimating that their project(s) will enter into the clinic in 2019.

The upcoming phase I study with ATOR-1015 is a first-in-human dose escalation study in patients with advanced solid cancer. The study will be conducted at five sites in Sweden and Denmark and will enroll up to 50 patients. The primary aim of the study is to investigate the safety and tolerability of ATOR-1015 and establish the recommended dose for the subsequent phase II studies. ATOR-1015 is intended to be the first CTLA-4 and OX40-binding bispecific antibody to achieve a strong anti-tumor effect, either as a monotherapy or in combination with currently established immunotherapies such as PD-1 and PD-L1 blockers. It is expected to be suitable for treating a large number of different forms of cancer.

"We are very pleased to announce the CTA submission and look forward to starting patient recruitment as fast as possible after regulatory approval. Based on a strong preclinical data package demonstrating that ATOR-1015 localizes to the tumor and selectively activates the immune system in the tumor area, we have high expectations of this first-in-class drug candidate," said Per Norlén CEO of Alligator Bioscience.

As previously communicated, Alligator has appointed Theradex Oncology, a global contract research organization with extensive expertise in oncology clinical development, to conduct the phase I study.

About ATOR-1015

ATOR-1015 is a next generation CTLA-4 bispecific antibody developed for tumor-directed immunotherapy with increased capability of regulatory T-cell depletion. It is wholly-owned by Alligator. ATOR-1015 binds to two different immune receptors: the checkpoint receptor CTLA-4 and the co-stimulatory receptor OX40. The immune activation is increased in areas where both target molecules are expressed at high levels, notably in the tumor microenvironment, which is believed to reduce adverse immune reactions.
