This study is an open-label, dose-escalation Phase 1 clinical study, and conducted in several institutions across the US including Sarah Cannon Research Institute (Florida Cancer Specialists & Research Institute), University of Southern California, and the Washington University in St. Louis. The primary objective of this study is to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT); the secondary objective is to evaluate the efficacy and pharmacokinetic profile of UTD2 monotherapy in patients with advanced solid tumors.

Five dose cohorts were explored in this study. After confirming the DLT (diarrhea) in the highest dose cohort, 75mg/m2/day x 5 days was determined as MTD. A total of 18 patients with more than 10 different types of advanced solid tumors were enrolled. The median age was 63 years old, and 2/3 of the patients had received ≥ 3 lines of prior treatments. As of now, efficacy evaluations were completed in 12 patients, and 1 complete response (CR, ovarian cancer), 1 partial response (PR, ovarian cancer), and 8 stable disease (SD, prostate cancer, testicular cancer, non-small cell lung cancer, pancreatic cancer, appendix adenocarcinoma, soft tissue sarcoma, etc.) were obtained with a clinical benefit rate of 83%. The results further demonstrated the broad-spectrum anti-tumor property of Utidelone. As for treatment duration, more than half of these patients received ≥3 cycles of treatments, and the maximum duration of response reached 36 weeks. In terms of safety, most treatment-related adverse events (TRAEs) were grade 1-2, and the most frequently seen TRAEs (incidence ≥ 20%, including all grades) were diarrhea (55.6%), fatigue (33.3%), and neutropenia (22.2%), all of which were manageable. The preliminary results of this study were also presented at the 2024 ASCO (Free ASCO Whitepaper) meeting.

Dr. Li Tang, Chairman of Biostar Pharma commented: "This is the first study of UTD2 that has completed enrollment globally. We successfully achieved the primary objectives and observed encouraging efficacy and safety profiles. We are very grateful for the joint engagement and dedication of our US clinical institutions and investigators. We are confident that this blockbuster product will substantially change the administration regimen of microtubule inhibitors. We will advance the following pipelines for UTD2 at full speed and hopefully bring it to the market to benefit global cancer patients as soon as possible".

Biostar is actively carrying out clinical studies of UTD2 in China and abroad. A pivotal study in China for advanced breast cancer led by Professor Xu Binghe, Cancer Hospital of Chinese Academy of Medical Sciences, is in recruitment. The preliminary findings of this study were also presented at the ASCO (Free ASCO Whitepaper) meeting in 2024; the China Phase 2 study for advanced solid tumors including ovarian cancer and cholangiocarcinoma, etc. is in initiation. In addition, US FDA has granted an Orphan Drug Designation (ODD) to UTD2 for the treatment of advanced gastric cancer, and Biostar is preparing for IND filing of a Phase 2/3 multi-reginal clinical study (MRCT) led by Professor Ruihua Xu of Sun Yat-sen University Cancer Center in both China and US simultaneously.

Utidelone is a new-generation genetically engineered microtubule inhibitor. Utidelone Injection (UTD1) has been launched in China in 2021 for the treatment of metastatic breast cancer (MBC) progressed after at least one anthracycline- or taxane-containing chemotherapy regimen. The phase 3 study data showed that UTD1 is the only one to achieve both PFS and OS benefits for heavily pretreated MBC patients, and the results were twice orally presented at ASCO (Free ASCO Whitepaper) annual meetings. Utidelone has similar mechanism of action with that of taxanes while demonstrating multiple advantages, including better anti-tumor activity, broader anti-tumor spectrum, better safety profile with very low hematologic toxicity, effective against multidrug-resistant tumors with less prone to develop drug resistance, capability of crossing the blood-brain barrier so as to prevent and treat brain tumor, and high oral bioavailability. Multiple indication expansion clinical studies for UTD1 are also in progress in China and US, including but not limited to MRCT Phase 3 study for non-small-cell lung cancer (NSCLC), Phase 2 pivotal study for breast cancer brain metastasis in US and NSCLC brain metastasis in China, and Phase 3 study for breast cancer neoadjuvant in China.

Compared to taxanes, which are difficult for oral formulation development, Utidelone is not susceptible to P-glycoprotein thus cannot be pumped out of the cancer cell by P-glycoprotein and has the advantage for higher oral bioavailability. By utilizing its synthetic biology technology platform, Biostar developed Utidelone Capsule, and its efficacy and safety have been confirmed in both US and China’s studies. Utidelone Capsule will significantly improve the convenience of administration, compliance of patients, decrease in treatment cost and ease of combination therapy with other oral anti-cancer drugs, meaning more suitable for adjuvant and maintenance therapy.

Currently, the trial has successfully dosed 6 patients with their first of 4 possible doses at the higher dose level. Each 5mL dose contains up to 230 million gamma delta T cells, and a patient is expected to receive up to an approximate 1 billion gamma delta T cells over four doses. Five patients have received their second dose, with 2 of these patients having also received their third dose. This correlates with TCBP’s step-wise approach to process improvements, as implemented in Q4 2023, and further steps taken to amend the trial protocol in the first quarter of 2024. New patients will continue to be identified, screened, and enrolled into the study.

"TCBP is excited to announce our rapid progression in the ACHIEVE Phase 2b trial with very strong enrolment in the second part of the trial using the higher dose," stated, Bryan Kobel, CEO of TC BioPharm. "TCB008 is potentially a game-changing monotherapy for blood cancers, and the strong recruitment and patient retention rates are testament to clinician/physician interest in TCB008 as a monotherapy in leukemia. We’re proud of the milestones accomplished to date, having rapidly dosed 6 patients with an additional 10 patients lined up. It is encouraging to see re-dosing of several patients, which we believe reflects positively on the steps the organization took in 2023 and early 2024. TCBP remains poised to execute on our clinical trial plans in 2024 and into 2025, including ACHIEVE and ACHIEVE2, as well as our expanded manufacturing capabilities to enhance our operational capabilities and our economic efficiencies."

The ACHIEVE UK clinical trial is an open-label, phase II study designed to evaluate the efficacy and effectiveness of TCB008 in patients with AML or MDS/AML, with either refractory or relapsed disease.

TLX101 (4-L-[ 131I] iodo-phenylalanine, or 131I-IPA) is a systemically administered targeted radiation therapy that targets L-type amino acid transporter 1 (LAT1), which is typically over-expressed in GBM.

In the first peer-reviewed publication of the IPAX-1 study, Professor Josef Pichler and colleagues report that single or fractionated doses of TLX101 plus EBRT were associated with acceptable tolerability and specific tumour-targeting in patients with recurrent GBM. Authors explain that the study delivered encouraging preliminary efficacy data, demonstrating a median overall survival (OS) of 13 months from the initiation of treatment, or 23 months from initial diagnosis. Given that GBM has a median survival from initial diagnosis of 12-15 months, authors conclude that findings from the IPAX-1 study "support further investigation into the use of TLX101 plus EBRT, including its potential as a first line treatment".

Key findings of the IPAX-1 study, outlined in the paper, include:

All dosing regimens were well tolerated.
Organ-absorbed radiation doses in the red bone marrow (0.38 Gy) and kidney (1.28 Gy) confirmed no radiation-based toxicity.
Stable disease with MRI[1] assessment was observed in 4 of 9 patients at 3 months post-treatment (3-month follow-up, 1 patient did not reach protocol-mandated end of study), yielding a response rate of 44.4%.
At the 3-month follow-up, 6 patients demonstrated metabolic stable disease with 18F-FET PET imaging.
Median progression-free survival was 4.3 months (95% confidence interval, 3.3–4.5), while median OS was 13 months from the initiation of treatment (95% confidence interval, 7.1–27), or 23 months from initial diagnosis.
Metabolic tumour responses were determined using Telix’s investigational PET[2] agent for glioma imaging, TLX101-CDx (Pixclara[3], 18F-floretyrosine or 18F-FET).

Professor Josef Pichler, Kepler University Hospital, Austria, Principal Investigator in the IPAX-1, IPAX-2 and IPAX-Linz studies, and lead author, commented, "A significant unmet need exists for well-tolerated and efficacious treatments for patients with glioblastoma. The results from this Phase I study demonstrate the favourable safety and tolerability profile and preliminary efficacy of TLX101 in combination with second-line EBRT, in patients with recurrent glioblastoma. Following treatment with TLX101 plus EBRT, stable disease was observed in 44% of patients at 3 months post-treatment and median progression-free survival was 4.3 months, with no confirmed radiation toxicity. The overall survival improvement trend seen in this patient population clearly warrants further investigation into the use of TLX101 plus EBRT, including its potential as a first-line treatment. These studies are now well advanced."

Dr David N Cade, Chief Medical Officer at Telix said, "We believe that TLX101 has significant potential to improve outcomes for patients living with glioblastoma – a disease in urgent need of new treatment options. In the front-line setting, the standard of care has not advanced materially in almost two decades, and in recurrent disease, no standard treatment exists. We are encouraged by these data, which show that TLX101, in combination with EBRT, is well tolerated at the doses tested, with preliminary clinical evidence demonstrating an anti-tumour effect and disease stabilisation – outcomes that are very important for this advanced patient population. Telix is pleased to be at the forefront of developing a new therapy for glioblastoma, and we welcome the excellent work conducted by Professor Pichler and his colleagues to progress this."

The IPAX-2 and IPAX-Linz studies in the front-line and recurrent settings continue to progress well in combination with standard of care, and using Telix’s Pixclara3 investigational PET agent as companion diagnostic. Data from IPAX-1, together with these studies, will inform the design of Telix’s future registration-enabling trial for TLX101.

About TLX101

TLX101 is Telix’s LAT1-targeting investigational therapy for patients with brain cancer. TLX101 therapy utilises a small molecule approach due to the need to cross the blood brain barrier, the normal protective barrier that prevents many potential drug candidates entering the brain. TLX101 has received orphan drug designation in the U.S. and Europe for the treatment of glioma.

About the IPAX series of studies

IPAX-1 was a multicenter, open-label, single-arm Phase I study to evaluate TLX101 plus EBRT in patients with recurrent GBM. The primary objective of the IPAX-1 study was to evaluate the safety and tolerability profile of intravenous TLX101 administered concurrently with second line EBRT. Secondary objectives were to determine optimal dosing, biodistribution and radiation absorption into the tumour, as well as assess preliminary efficacy through clinical and imaging-based assessment of tumour response. ClinicalTrials.gov ID: NCT03849105.
IPAX-2 is a Phase I study of TLX101 in combination with post-surgical standard of care treatment in patients with newly diagnosed GBM. Active, dosing patients. ClinicalTrials.gov ID: NCT05450744.
IPAX-Linz is a Phase II investigator-initiated trial of TLX101 in combination with EBRT in patients with recurrent high-grade gliomas (HGG), including GBM. Active, dosing patients.

On September 3, 2024 Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncology, cardiovascular and metabolic, autoimmune, ophthalmology and other major diseases, reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation to its PD-1/IL-2α Bispecific Antibody Fusion Protein (R&D code: IBI363) for the treatment of unresectable locally advanced or metastatic melanoma (except choroidal melanoma) in patients who have progressed after at least one line of systemic therapy, which must include a PD-1/L1 inhibitor (Press release, Innovent Biologics, SEP 3, 2024, View Source [SID1234646318]). Phase 1/2 clinical trials are currently underway in China, the U.S., and Australia to assess IBI363’s efficacy and safety in various advanced malignant tumors.

At the ESMO (Free ESMO Whitepaper) Plenary meeting on June 14, 2024, Innovent presented promising efficacy signals in melanoma patients who had previously undergone immunotherapy: 37 patients with melanoma who had previously received immunotherapy received 1mg/kg of IBI363 and underwent at least one tumor evaluation after baseline, and 11 patients achieved objective responses, including 1 CR and 10 PR, with ORR and DCR of 29.7% and 73.0%, respectively. (Link)

Dr. Hui Zhou, Senior Vice President of Innovent, said, "Melanoma is the most common fatal skin cancer in Europe and the United States. In China, while melanoma is a rare malignant tumor, it has a high fatality rate, and its incidence is steadily increasing each year. Despite the success of immune checkpoint inhibitors in the treatment of melanoma, there is currently no drug approved for immunotherapy failed melanoma around the world, and the ORR of traditional chemotherapy ± anti-vascular therapy for immunotherapy failed melanoma is only 3.8% to 6.8%, with a median PFS of less than 3 months, and the benefit is very limited[1]-[2]. Therefore, there is an urgent clinical need for patients who have previously failed immunotherapy. As a First in-class PD-1/IL-2α-bias bispecific antibody fusion protein, IBI363 monotherapy has shown encouraging efficacy and a favorable safety profile in melanoma subjects who have previously received immunotherapy. We will continue to explore the efficacy and safety of IBI363 in melanoma to provide more effective clinical treatment for patients with immune-resistant melanoma."

Fast Track Designation (FTD) is a rapid review process designed to facilitate the clinical development of a drug that may treat serious conditions and fulfill an unmet medical need. According to regulations, drug candidates that obtain FTD qualifications will have more opportunities to communicate with the FDA during subsequent drug development and review processes, which will help speed up the clinical development and approval of the drug.

About Melanoma

Melanoma is a malignant tumor that develops from melanocytes and is the fifth most common cause of cancer in the United States[3]. Although melanoma represents only 3% of all skin cancer cases, it has the highest mortality rate and is the most prone to metastasize. In China, both the incidence and mortality rates of melanoma have been steadily rising over the years. According to the classification of the disease site, melanoma is mainly divided into skin melanoma, acral and mucosal melanoma. Chinese melanoma differs greatly from European and American Caucasian melanoma in pathogenesis, biological behavior, histological morphology, treatment and prognosis[4]. For advanced cutaneous and acral melanomas, for those carrying BRAF V600 mutation, BRAF inhibitor combined with MEK inhibitor is the preferred molecular targeted therapy. For patients without a BRAF V600 mutation, comination of chemotherapy and anti-angiogenic drugs may be considered as the first-line treatment. Immunotherapy has not been approved as the first-line treatment indication for advanced melanoma in China. For second-line treatment, therapies not used in the first-line are recommended. If a PD-1 monoclonal antibody was not administered initially, it can be selected for the second-line. In advanced mucosal melanoma, chemotherapy or a combination of PD-1 monoclonal antibody and anti-angiogenic drugs may be considered as first-line options. For patients with BRAF V600 mutation, a BRAF inhibitor ±MEK inhibitor can be chosen. Currently, posterior treatment options for melanoma are very limited[5].

About IBI363 (PD-1/IL-2α)

IBI363 is a first-in-class drug candidate independently developed by Innovent Biologics. Its active ingredient is PD-1/IL-2 bispecific antibody fusion protein. The IL-2 arm of IBI363 has been engineered to maximize efficacy and reduce toxicity, whereas the PD-1 binding arm achieves PD-1 blockade and selective IL-2 delivery. Therefore, IBI363 functions by simultaneously blocking the PD-1/PD-L1 pathway and activating the IL-2 pathway, enabling more precise and efficient targeting and activation of tumor specific T cells. IBI363 has demonstrated notable anti-tumor activity across various tumor-bearing pharmacological models and showed significant antitumor efficacy in both PD-1 resistant and metastatic models. Additionally, IBI363 exhibited a favorable safety profile in preclinical models. Clinical studies of IBI363 are currently underway in China, the United States, and Australia to evaluate its safety, tolerability and preliminary efficacy in subjects with advanced malignancies.
