About Osemitamab (TST001)

Osemitamab (TST001) is a high affinity humanized anti- CLDN18.2 monoclonal antibody with enhanced antibody-dependent cellular cytotoxicity ("ADCC"). It has shown potent anti-tumor activities in tumor xenograft models. Osemitamab (TST001) is the second most advanced CLDN18.2 targeting antibody being developed globally. Osemitamab (TST001) was generated using Transcenta’s Immune Tolerance Breaking Technology (IMTB) platform. Osemitamab (TST001) kills CLDN18.2 expressing tumor cells by mechanisms of ADCC. Leveraging advanced bioprocessing technology, the fucose content of Osemitamab (TST001) was significantly reduced during the production, which further enhanced NK cells mediated ADCC activity of Osemitamab (TST001). Clinical trials for Osemitamab (TST001) are ongoing in the U.S. and China (NCT05190575, NCT04396821, NCT04495296, NCT05608785 / CTR20201281). Osemitamab (TST001) was granted Orphan Drug Designation in the U.S. by FDA for the treatment of patients with gastric or gastroesophageal junction (G/GEJ) and pancreatic cancer.

WU-NK-101 is Wugen’s lead memory natural killer (NK) cell therapy product and is comprised of cells optimized for anti-cancer function. WU-NK-101 cells possess a unique cytokine-induced memory-like (CIML) phenotype that supports enhanced anti-tumor activity, robust trafficking, superior proliferation capacity, and metabolic flexibility, all of which contribute to treatment resilience in the adverse tumor microenvironment (TME). WU-NK-101 is produced with the company’s proprietary MonetaTM manufacturing platform, which enables robust generation of off-the-shelf memory NK cell-based therapies.

"The start of this clinical trial is a significant step forward in our memory NK cell program, which we believe offers significant advantages over other NK cell therapy approaches and has the potential to benefit patients with a number of tumor types," said Jan Davidson-Moncada, M.D., Ph.D., chief medical officer of Wugen. "Early clinical studies with memory NK cells demonstrated impressive response rates in patients with AML, even those with a high disease burden. We look forward to building on these data while advancing WU-NK-101 as a readily accessible allogeneic cell product. In tandem, we are proud to announce our Orphan Drug Designation for WU-NK-101, which will enhance our efforts to deliver this therapy to AML patients."

"Today’s news represents a significant milestone for Wugen, as WU-NK-101 is the first therapeutic candidate from our memory NK cell platform to enter the clinic," added Kumar Srinivasan, Ph.D., president and chief executive officer of Wugen. "Beginning in AML, where there remains a high unmet need for new therapeutic options, our goal is to deploy our memory NK cell platform to deliver next-generation, best-in-class allogeneic memory NK cell therapies to transform cancer care, including treatment of solid tumors."

The Phase 1 study is a global, open-label, dose-escalation, and cohort expansion study designed to characterize the safety and tolerability of WU-NK-101 in patients with r/r AML and determine the recommended Phase 2 dose. It will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary anti-leukemic activity of WU-NK-101. WU-NK-101 will be administered as three weekly infusions in a 28-day cycle. Additional information is available on clinicaltrials.gov, identifier NCT05470140.

An abstract on the design of the Phase 1 trial was published in the November 2022 supplemental issue of Blood, the journal of the American Society of Hematology (ASH) (Free ASH Whitepaper).

Memory NK cells have been clinically validated for safety and efficacy in AML. In addition, solid tumor preclinical studies of WU-NK-101 suggest efficacy in solid tumors alone or in combination with monoclonal antibodies.

The FDA Office of Orphan Products Development grants orphan designation for novel drugs or biologics being developed to treat a rare disease or condition affecting fewer than 200,000 patients in the United States. ODD qualifies the sponsor of the drug for various development incentives of the Orphan Drug Act, including potentially seven years of U.S. marketing exclusivity, tax credits for clinical research costs, clinical research trial design assistance, the ability to apply for annual grant funding and waiver of Prescription Drug User Fee Act filing fees.

About WU-NK-101

WU-NK-101 is a novel immunotherapy harnessing the power of memory natural killer (NK) cells to treat liquid and solid tumors. Memory NK cells are hyper-functional, long-lasting immune cells that exhibit enhanced anti-tumor activity and a cytokine-induced memory-like (CIML) phenotype. This rare cell population has a superior phenotype, proliferation capacity, and metabolic fitness, making it better suited for cancer therapy than other NK cell therapies. Wugen is applying its proprietary MonetaTM platform to advance WU-NK-101 as a commercially scalable, off-the-shelf cell therapy for cancer. WU-NK-101 is currently in development for acute myelogenous leukemia (AML). Wugen is planning to initiate solid tumor studies of WU-NK-101 in combination with cetuximab. Studies of WU-NK-101 to date have shown promising robust in vivo activity in various tumor indications, retention of anti-cancer activity in TME, resistance to immune suppression, and enhanced activity with checkpoint inhibitors.

About the MonetaTM Platform

BNCT stands out as an innovative and distinctive biologically-targeted radiation therapy that employs a non-toxic boron-10 compound and a neutron source. When exposed to a low-energy neutron beam, this boronated compound triggers a targeted reaction, effectively eliminating cancer cells while preserving healthy tissue.

TAE Life Sciences has made a remarkable breakthrough with their exclusive drug, TC220, representing a significant leap forward in BNCT. Notably, TC220 offers several key advantages over conventional boronophenylalanine (BPA) as the boron target drug. Through pre-clinical studies, TC220 has demonstrated its ability to deliver boron more effectively to tumor cells compared to BPA. This is attributed to its enhanced solubility, prolonged retention in tumor tissue, and consistent and superior boron delivery in multiple human tumor xenografts. With these exceptional attributes, TC220 holds the potential to be applied across a broader range of clinical scenarios, thereby expanding the horizons of BNCT as a next-generation cancer treatment.

"We are driven by the mission to bring our biologically targeted radiation therapy to those fighting aggressive and recurrent cancers," said Kendall Morrison, Ph.D., Chief Science Officer at TAE Life Sciences. "This exclusive supplier deal with Biddle Sawyer and Kinentia Biosciences represents a significant milestone in our journey to deliver cutting-edge cancer treatments to patients in need."

BNCT has shown promising outcomes in clinical studies worldwide. With the availability of better boron-10 drugs like TC220 and an in-hospital neutron system like TAE Life Sciences’ Alphabeam, there is a unique opportunity to improve patient care and treatment economics while reducing the burden and stresses of cancer treatment on the body.

Clinical trials for Alphabeam and proprietary boron-containing drugs are expected to commence in the United States and Europe in 2024.

The Peter Mac Cancer Center is a world leading cancer research, education and treatment center and Australia’s only public health service dedicated to caring for people affected by cancer. They have 3,900 employees, including more than 750 laboratory and clinical researchers, all focused on providing better treatments, better care and potential cures for cancer. They are well placed to support the Company’s goals for a world first clinical study of PRP, as a long term, proenzyme therapy for the treatment and prevention of metastatic cancer from solid tumors by targeting and eradicating cancer stem cells, free from side effects normally associated with standard treatment approaches.

"We are pleased to have engaged in positive initial discussion with Professor Mark Rosenthal, Director and FIH Clinical Study Investigator at the Peter Mac Cancer Center," said James Nathanielsz, BAS, MEI, Propanc’s Chief Executive Officer. "We are excited about the opportunity to work with a world class facility like Peter Mac, and it was great to see our mutual excitement about a potential world first study for PRP as a new therapeutic approach to treat and prevent metastatic cancer from solid tumors. Our plan is to undertake the FIH study in Australia, given the favorable R&D cashback benefit where we will receive 43% of our R&D expenditure on local activities, as well as approval from the Australian Government for reimbursement some overseas activities as well. We will then plan to undertake subsequent clinical studies in Europe, as the preeminent region behind the USA, where we will undertake a Pre-IND meeting with the US Food and Drug Administration once we have clinical data from our FIH study. Achieving this exciting development stage in the not-too-distant future could prove transformative for the Company, and its shareholders."

Propanc is set to capitalize on favorable government incentives from the Australian government for future product and clinical development of PRP, receiving a 43.5% cash back benefit on all local R&D activities conducted in Australia. Furthermore, a Certificate for Advance Overseas Finding was received from the Board of Innovation and Science Australia to receive up to a 43.5% "cash back" benefit from overseas R&D expenses. Overseas activities to be undertaken include validation of the pharmacokinetics method for PRP and its manufacture of the finished product for the FIH study.
