Cluster of differentiation 47 (also known as integrin-associated protein) ("CD47") is a ubiquitously-expressed glycoprotein of the immunoglobulin superfamily that plays a critical role in self-recognition. Various solid and hematologic cancers exploit CD47 expression to evade immunological eradication, and its overexpression is clinically correlated with poor prognoses. One essential mechanism behind CD47-mediated immune evasion is that it can interact with signal regulatory protein-alpha (SIRPα) expressed on myeloid cells, causing phosphorylation of the SIRPα cytoplasmic immunoreceptor tyrosine-based inhibition motifs and recruitment of Src homology 2 domain-containing tyrosine phosphatases to ultimately result in delivering an anti-phagocytic "don’t eat me" signal. Given its essential role as a negative checkpoint for innate immunity and subsequent adaptive immunity, the CD47/SIRPα axis has been explored as a new target for cancer immunotherapy and its disruption has demonstrated great therapeutic promise.

In preclinical evaluations, STI-6643 displayed decreased red blood cell binding and hemolysis, while maintaining potent anti-tumor activity in solid tumor disease models. Clinical trials with anti-CD47 mAbs have historically experienced limitations due to significant anemia, hemagglutination, and thrombocytopenia due to CD47 expression on normal red blood cells, ultimately requiring employment of complicated clinical dosing regimens. These issues have not been seen to date with STI-6643 in preclinical studies conducted head-to-head against synthesized versions of other CD47 mAbs. Additionally, STI-6643 showed minimal T, B or NK cell depletion as opposed to other synthesized mAb clones, which could potentially result in improved efficacy by preserving infiltrating anti-tumor immune cells. STI-6643 has the potential to be a "best-in-class" product if these preclinical benefits are able to be reproduced in human trials. Sorrento is also conducting preclinical studies to compare the safety and efficacy of lymphatic delivery of STI-6643 to established parenteral routes of administration using Sorrento’s Sofusa technology. This study will be conducted at the Moffitt Cancer Center in Tampa, FL with Dr. David A. Sallman as the coordinating lead investigator.

STI-6643 is the second anti-CD47 antibody that has been developed from the G-MAB library. The other anti-CD47 antibody (IMC-002) discovered from the G-MAB library was previously cleared by the FDA, and is currently in Phase 1 human studies sponsored by ImmuneOncia Therapeutics, LLC, a joint venture company between Sorrento (35% ownership) and Yuhan Corporation.

Regarding the recent clearance for a clinical trial for STI-6643 by the FDA, Dr. Henry Ji, Chairman and CEO of Sorrento, commented, "We have seen great performance from STI-6643 in our IND-enabling studies. Our internal anti-CD47 program has now yielded two clinical candidates, a signal of our continued commitment to the development of innovative, safe and efficacious cancer treatments in addition to our commitment to fighting COVID-19."

PRECLINICAL DATA ON NBTXR3 COMBO

NBTXR3 is composed of sterile, functionalized, crystalline hafnium oxide nanoparticles that are delivered by intratumoral injection one time prior to radiotherapy (XRT). After activation by XRT, the product candidate has a physical primary mechanism of action through which a higher dose of radiation is delivered within the tumor, enhancing the tumor-killing effect of XRT without increasing the dose in surrounding healthy tissues. The subsequent biological secondary mechanism of action that we are evaluating is the potential activation of several immune pathways upon tumor cell destruction, generating adaptive immune response within the body.

NBTXR3 is being evaluated in an expansive global development plan both as a single agent activated by XRT and in combination with other anti-cancer therapies including chemotherapy and immune checkpoint inhibitors. This study examined NBTXR3 activated by XRT in combination with anti-PD-1 along with TIGIT and LAG3 inhibitors in an in vivo anti-PD-1 resistant mouse model (344SQR).

Key Findings Include:

The combination therapy of NBTXR3 + XRT + anti-PD-1 + anti-LAG3 + anti-TIGIT (Combo therapy) significantly promoted the proliferation activity of CD8+ T cells, improved local and distant tumor control, and increased survival rate
The anti-tumor efficacy of the Combo therapy was heavily dependent on CD4+ and CD8+ Tcells
The survivor mice from the groups treated with the Combo therapy were immune to re-injections of tumor cells
The survivor mice maintained significantly higher percentages of memory CD4+ and CD8+ T cells, as well as stronger anti-tumor immune activities than control
The Combo therapy augmented anti-tumor response in both irradiated and unirradiated (abscopal) tumors

About NBTXR3

NBTXR3 is a first-in-class radioenhancer composed of sterile, functionalized, crystalline hafnium oxide nanoparticles. The product candidate is designed to increase the radiotherapy energy deposit inside tumor cells through the nanoparticles’ high atomic number core packaged in the space for interaction with ionizing radiation, and subsequently increase of tumor cell death when compared to radiotherapy alone—without adding toxicity to adjacent healthy tissues. NBTXR3 requires a single, intratumoral administration before the first radiotherapy treatment session, and has the ability to fit into current worldwide standards of radiation care. The primary physical mechanism of action of NBTXR3 activated by radiotherapy could be universal, making it potentially applicable across any solid tumor indication where radiotherapy is a part of standard of care including head and neck, lung, prostate, liver, colorectal, and esophageal cancers. The biological secondary mechanism of action of NBTXR3 activated by radiotherapy has been shown in preclinical studies to prime adaptive immune response, which would potentially bring a new dimension to cancer immunotherapies.

About NVX-CoV2373

NVX-CoV2373 is a protein-based vaccine candidate engineered from the genetic sequence of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax’ recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is adjuvanted with Novavax’ patented saponin-based Matrix-M to enhance the immune response and stimulate high levels of neutralizing antibodies. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19. In preclinical studies, NVX-CoV2373 induced antibodies that block binding of the spike protein to cellular receptors and provided protection from infection and disease. It was generally well-tolerated and elicited robust antibody response numerically superior to that seen in human convalescent sera in Phase 1/2 clinical testing. NVX-CoV2373 is currently being evaluated in two pivotal Phase 3 trials: a trial in the U.K that demonstrated 89.3 percent overall efficacy and 95.6 percent against the original strain in a post-hoc analysis, and the PREVENT-19 trial in the U.S. and Mexico that began in December. It is also being tested in two ongoing Phase 2 studies that began in August: A Phase 2b trial in South Africa that demonstrated 50-60 percent efficacy against newly emerging escape variants, and a Phase 1/2 continuation in the U.S. and Australia.
