Bonus BioGroup is a clinical-stage biotechnology company focused on developing next-generation therapeutics in the fields of tissue regeneration and biotechnological products based on tissue engineering and cell therapy.
BonoFill™, our injectable human live bone graft, grown outside the patient body, based on their own cells, is undergoing a multi-center Phase II clinical trial in patients suffering from critical-sized defects in long bones, in five medical centers across Israel, and Phase II study in patients with critical-sized defects in craniomaxillofacial bones.
MesenCure™ is our cell therapy product, based on banked and professionalized cells derived from healthy donors. We have recently concluded a multi-center Phase II clinical trial in hospitalized, severe COVID patients suffering from pneumonia and life-threatening respiratory distress, demonstrating the efficacy and safety of MesenCure™ compared to the standard of care.

Bonus BioGroup strives to become a global leader in Next-Generation Therapies in the fields of cell therapy and tissue engineering to improve human health.
Our mission is to help millions of people to live a better and longer life by merging innovative biological sciences and biomedical and biotechnology engineering.

Patients
The total addressable market for treating severe/critical COVID patients and non-COVID ARDS patients who could benefit from MesenCure after the pandemic
reduction in hospitalization cost as a result of using MesenCure
are expected to be treated with MesenCure, annually, after the pandemic

The total addressable for treating various bone defects in patients who could benefit from BonoFill
reduction in hospitalization and operations costs as a result of using BonoFill; of which \$15B in orthopedic and \$10B in craniomaxillofacial indications

According to analysis by McKinsey & Company (forecast 2030)



Currently, two bone-filling alternatives (inferior to Bonus BioGroup's technology)

Bonus BioGroup's injectable, live human bone graft , is designed to replace the unsatisfactory existing treatments

BonoFillTM is a bone graft made of a 3D culture of mesenchymal cells isolated from the patient's adipose tissue and grown on natural mineral scaffolds in a specialized bioreactor.
BonoFillTM is intended for the treatment of various bone deficiencies, including complex and criticalsized bone defects in craniomaxillofacial and orthopedic indications.







BonoFillTM An Injectable, Autologous, Viable Bone Graft Our Solution:


High quality bone graft which is biologically identical to natural bone
Personalized, autologous bone graft, made from the patient's own cells, with significantly reduced risks of immunological rejection or surgical failure
Provides improved and accelerated bone regeneration, compared to current solutions

Repair and regeneration of a 3.2 cm critical-sized bone defect

Complete bridging of the bone gap achieved within 7 weeks after BonoFill™ transplantation


The Repair of Large Critical-Sized Bone Defects
Bone repair of a 10cm critical-sized bone gap with BonoFillTM was achieved in 2 months
Results demonstrate the properties and potential of BonoFillTM injectable bone graft

First-in-human, phase I/II in Maxillofacial Indication with BonoFillTM (1 st generation):
Significant bone regeneration and recovery at the treatment site within 3 months following BonoFillTM transplant
Significant bone tissue augmentation, an average of 6.3 mm new augmented bone
Participants underwent successful placement of multiple dental implants within the new bone
A complete safety was demonstrated, No treatment-related adverse events occurred

Phase I/II clinical trials with BonoFillTM, 2 nd generation, in the following indications



Clinical Trial interim Results in the Maxillofacial Indication of Bone augmentation in the sinus and Filling Bone Voids


No treatment-related adverse events occurred

Participants underwent successful placement of multiple dental implants within the new bone

Pre transplant, all patients suffered from low quality residual upper jawbone and insufficient bone height for dental implantation

Pre transplant, the patients' average residual bone height was 6.6 mm

Three months following BonoFillTM transplantation, average bone height was 14.8 mm

Six months following BonoFillTM transplantation, average bone height 15.8 mm, demonstrating new bone growth of 9.2 mm

When Danny Yaakobson, an extreme sports enthusiast, suffered a serious leg injury following a car accident, he did not imagine he would become the world's first patient to receive Bonus BioGroup's lab-grown bone implant, made from his own fat cells, to replace a missing section of his shinbone, let alone take part in the ISRAMAN triathlon just a year following the surgery (as seen in the previous slide).

MesenCure: A professionalized cell therapy product based on primed and standardized allogeneic adipose MSCs, dedicated to the treatment of pneumonia and ARDS



A robust allogeneic, adipose-derived MSC-based therapy enhanced to treat ARDS, including in severe COVID patients


MesenCure, but not Non-Activated MSCs, Reduce Lung Edema by 66%

Reduced lung weights following MesenCure treatment, relative to diseased untreated lungs (Vehicle Control) or lungs treated by nonactivated MSCs is indicative of reduced edema that is typical and lifethreatening in COVID pneumonia.

Reduction in the levels of immune cells in the diseased lungs, following MesenCure treatment and relative to diseased untreated lungs (Vehicle Control), is indicative of reduced pneumonia and better prognosis






MesenCure reduces the infiltration of immune cells into the lungs healing pneumonia within less than 24 hours
