According to the terms of the agreement, Simcere Zaiming will acquire exclusive commercial rights to TGRX-326 in Mainland China. These rights encompass but are not limited to marketing promotion, strategy formulation and adjustment, and the right to obtain relevant benefits from TGRX-326. TargetRx will receive an initial payment exceeding $20 million. Additionally, TargetRx will compensate Simcere Zaiming for promotional services.

TGRX-326 is a third-generation anaplastic lymphoma kinase (ALK) inhibitor independently developed by TargetRx. It is a potent and highly selective small molecule inhibitor that targets ALK and c-ROS proto-oncogene 1 (ROS1) receptor tyrosine kinases (RTKs). This inhibitor holds significant therapeutic potential for ALK/ROS1 fusion gene-positive non-small cell lung cancer (NSCLC) patients, especially those with multiple ALK-resistant mutations, including G1202R.

In preclinical studies and a Phase 1 clinical trial, TGRX-326 demonstrated robust anti-tumor activity and a favorable safety profile. Moreover, the molecule effectively crosses the blood-brain barrier, exhibiting exceptional efficacy in NSCLC patients with brain metastases.

Dr. Renhong Tang, Chairman of Simcere Zaiming, said, "We are pleased to collaborate with TargetRx on novel dual-targeted therapy for lung cancer, a major malignancy that Simcere Zaiming strategically focuses on. This partnership will further enhance our innovative product portfolio. ALK/ROS1 fusion is a critical genetic mutation in non-small cell lung cancer. The advancement of targeted therapies has significantly improved survival rates for these patients. However, there remains a substantial need for new treatments with better efficacy and the ability to overcome drug resistance. We look forward to working closely with TargetRx to provide Chinese lung cancer patients with more effective treatment options as soon as possible."

Dr. Yihan Wang, Chairman of TargetRx, said, "TGRX-326 is a potentially best-in-class novel anti-tumor molecule independently developed by TargetRx. It is a third-generation ALK inhibitor in late-stage clinical development which may bring a better option for patients. We believe that with the support of Simcere Zaiming, we will be able to bring this product quickly to the market. TargetRx aims to continuously deliver innovative therapies that will transform the lives of cancer patients."

Innovate UK, part of UK Research and Innovation, invests in innovative projects that are positioned to advance next-generation immunotherapies for cancer.

The grant will primarily support the Company’s upcoming Phase 1 multi-centre, open-label first-in-human trial to evaluate safety and tolerability of THEO-260 in patients with advanced-stage platinum-resistant ovarian cancer and determine the recommended Phase 2 dose. This trial is expected to begin in the coming months.

It will further allow for comprehensive analysis to elucidate and evidence THEO-260’s unique mechanism of action to destroy cancer cells and immune suppressive stromal cells, whilst also inducing T cell activation, through a comprehensive biomarker study, including the development of novel biomarker tests. Proceeds will also support the evolution of Theolytics as it continues to expand its footprint and reach as a clinical-stage oncology biotech company.

"This competitive award from Innovate UK in the category of "Transforming Cancer Therapeutics" reflects the novelty of our research as well as our ability to deliver operational excellence as we move forward to the clinic. This will allow us to precisely demonstrate the mechanism of action of THEO-260, which we anticipate will provide key information to enhance further development of this immunotherapeutic oncolytic virus and our wider platform," said Miriam Bazan Peregrino, Theolytics’ VP Translational Development.

About THEO-260

THEO-260 is a next-generation oncolytic adenovirus for the treatment of ovarian cancer. Positioned to tackle the complex, immune suppressed nature of advanced solid tumours. It demonstrates effective killing of cancer cells and cancer-associated fibroblasts (CAFs), whilst inducing immune activation in advanced preclinical models, including extensive panels of ovarian cancer patient samples. THEO-260 will be evaluated in Phase I clinical trials by intravenous and intraperitoneal delivery to ovarian cancer patients.

On September 2, 2024 : Imugene Limited (ASX:IMU), a clinical stage immuno-oncology company, reported promising results from its Phase 1b clinical trial with azer-cel (azercabtagene zapreleucel, an allogeneic off-the-shelf CD19 CAR T), in patients with relapsed/refractory diffuse large B cell lymphoma (DLBCL), a type of non-Hodgkin’s lymphoma (NHL) (Press release, Imugene, SEP 2, 2024, View Source [SID1234646253]). All enrolled patients had cancer that had returned following autologous CAR T therapy, a high unmet need for this patient population.

"We are delighted that the first 2 patients in the Cohort B in our azer-cel Phase 1b trial achieved a complete response and continue to maintain their complete responses, one for over 120 days and the other for over 90 days," said Paul Woodard, MD, Imugene’s Chief Medical Officer. "All four patients enrolled in Cohort B have failed 4 to 5 prior treatments, including autologous CAR T therapy. All 4 patients remain on the study and given the robust response rates and durability seen to date, we will continue to enrol patients in the azer-cel plus IL-2 cohort and will closely follow all patients for further responses and durability."

Patients in the trial are being recruited across 15 leading cancer centres in the U.S. including, Columbia University, University of Minnesota, Emory, and Moffitt Cancer Centres and plans are ongoing to open up to 5 sites in Australia.

Nine (9) patients total from Cohorts A and B are considered evaluable (qualified for at least day 28 scan). One (1) patient (Cohort B) has been treated and is awaiting their 28- day scan:

• Of the 6 evaluable patients in Cohort A:
o 1 CR, 1 PR = 33% Overall Response Rate (ORR)
o 1 CR = 17% CR
o Durability of response was < 60 days o All patients no longer on trial

• Of the 3 evaluable patients in Cohort B:
o 2 CRs = 67% ORR o 2 CRs = 67% CR
o 1 Stable Disease (SD)*: On PET/CT scan imaging, patient’s tumour has decreased however, due to potential T-cell infiltration, noted an increase in signal intensity. This could represent pseudoprogression. The patient remains on trial and continues to be assessed for response at the follow up scans.
o Durability of response thus far: >120 days and >90 days (all patients are ongoing)
o All 4 patients (including 1 patient awaiting 28-day scan) continue on trial.

"I am proud of our clinical development team who assessed ways to enhance azer-cel’s durability of response, as one of the biggest challenges in CAR T therapy is ensuring that the modified T-cells stay in the body long enough to kill cancer cells," said Leslie Chong, Managing Director and CEO of Imugene. "

To maximise the response rates and durability further, we added a very low dose of IL-2 to the regimen in Cohort B. We are pleased with the results, which suggest improved outcomes in patients, and we look forward to amassing more data using this dosing regimen. We will continue to seek biomarker evidence from Cohort B patients that suggest our strategy is improving the performance of azer-cel."

The company will continue to enrol additional patients in Cohort B and follow patients for durability of response with the goal of providing a comprehensive package to the FDA for the potential Phase 2/3 registrational trial. Subject to patient recruitment, the company aims to provide an interim Phase 1b data update.

If successful, azer-cel has the potential to become the first approved allogeneic CAR T cell therapy for blood cancer. Beyond studying its efficacy in blood cancers, in the future, Imugene plans to combine azer-cel with its novel onCARlytics program for the treatment of patients with solid tumours, opening a potentially large market for azer-cel in the 90% of cancer not classified as blood cancers.

acceptable safety profile. In addition, the current patients in Cohort B, treated with azercel, LD, and IL-2 are demonstrating clinically meaningful activity and durability.

About diffuse large B cell lymphoma (DLBCL)

DLBCL is an aggressive and fast-growing type of non-Hodgkin’s lymphoma (NHL), a type of blood cancer. DLBCL is the most common type of NHL, with approximately 80,500 cases per year and approximately 30,000 new cases per year in the U.S.2 Relapsed/refractory DLBCL has a high unmet medical need; 60-65% of patients treated with treatments, including autologous CD19 CAR T, relapse.

About Interleukin 2 (IL-2)

IL-2 is a cytokine (a protein that affects what happens between cells in the immune system) that helps T-cells (which are part of the immune system that help fight cancer) grow and survive. IL-2 has been shown to help T cells live longer and to enhance the cancer killing functions of CAR T cells, making them more effective at targeting and killing cancer cells.
