Leadingtac Bio was founded by Dr. Yan Feng in September 2019 in Zhangjiang Science Park. The company’s R&D direction is dedicated to the development of target protein degradation drugs and focuses on disease areas such as autoimmunity and oncology to address unmet clinical needs.

The target protein degradation drug is a bifunctional small molecule compound, a ligand that binds the target protein at one end and E3 ubiquitin ligase at the other. A Linker connects the ligands to form a complex that draws the target protein closer to the E3 ligase and promotes the ubiquitination of the target protein, which is then degraded through the ubiquitin-proteasome pathway to remove the disease-causing target protein. Targeted protein degradation drugs are characterized by high drug-forming ability, overcoming drug resistance, small dosage, low toxicity, and drug resistance. Therefore, this research direction has received close attention from domestic and international pharmaceutical companies and capital markets.

Since its inception, the company has taken the mission of "leading innovation, Thailand’s people", based on the source of innovation in new drug development, looking for new targets, using protein degradation technology to develop new small molecule drugs that are currently not drug-ready targets, to provide maximum therapeutic value for patients. As a result, we have developed a series of lead compounds with fully independent intellectual property rights based on our Nano-SPUD platform for specific protein ubiquitination and degradation drug discovery. The company’s fastest progressing project is the LT001 project for autoimmune diseases. The project has obtained expected results from a series of in vitro and in vivo experiments, such as degradation activity, pharmacokinetics, and efficacy, and has already carried out IND-enabling studies, which are expected to be submitted to IND at the end of 2022 and enter clinical trials in 2023. In addition, Leadingtac is also actively developing several pipeline projects.

Dr. Yan Feng, the founder of Leadingtac Bio, said, "As a significant direction for future drug development, the development of targeted protein degradation drugs (Protein Degrader) has received much attention from academia, the pharmaceutical industry, and the capital market in the past few years. As a newcomer in this field, Leadingtac has developed its R&D technology platform and pipeline within two years of its efforts. One of the pipelines will enter the clinical filing stage soon. In this financing round, Leadingtac was honored to receive the approval and lead investment from Yuan Sheng Venture Capital, and ZJ LEADING VC also decided to continue to invest. We are very grateful to our new and old investors for their recognition and support. This financing round will help to rapidly advance the clinical filing of Leadingtac’s first pipeline and also provide a strong guarantee for developing several subsequent projects, high-end talent team building, and site expansion. I believe that with the help of our investors and the efforts of the team at Leadingtac, we will be able to maximize our potential for new drug development and make greater contributions to the pharmaceutical field!"

Jay Chen, Founding Partner of Yuan Sheng Ventures, said, "We are pleased to invest in Leadingtac as the lead investor in this round. As a newcomer in the field of Protein Degrader, Leadingtac Bio has established a more mature technology platform, the first product has also started the filing of IND, and the subsequent product pipeline is various and has great potential for development. As a result, we believe Leadingtac Bio will have great international competitiveness in the future."

Yu Xiaoyong, the founding managing partner of ZJ LEADING VC, said, "We congratulate Leadingtac on the completion of this financing round. As the round angel investor of Leadingtac, we had the honor to work with Dr. Yan Feng two years ago to help Leadingtac plow through the new drug development track of protein degradation. Over the past two years, we have witnessed the continuous growth of Leadingtac’s team and the company together and have gained a deep understanding of the company’s continuous innovation powerhouse, which is why we have sufficient confidence in Leadingtac’s future development, and that is why we continue to invest in this round. We believe that after this round of financing, Leadingtac Bio will continue to achieve good results in the advancement of clinical filing projects, the layout of pipeline projects, and the reinforcement of the team."

The DIONE-01 study entitled "A Study to Assess a PI3Kδ Inhibitor (IOA-244) in Patients with Metastatic Cancers" (NCT04328844) consists of two parts, A and B. In Part A, now complete, the objective was to determine the safety, tolerability, and dosage of IOA-244 in cancer patients to determine the predicted biologically effective dose range. Safety, PK and PD data from Part A will be presented as a poster (#405) at ESMO (Free ESMO Whitepaper) IO in Geneva between December 8-11, 2021.

Part B of the DIONE-01 study consists of expansion cohorts of patients with different tumor types, including patients with metastatic uveal melanoma. It will include the assessment of whether IOA-244 can increase the anti-tumor immune response in patients both as monotherapy and in combination with pemetrexed/cisplatin and an immune checkpoint inhibitor. The study will enroll up to 182 patients with uveal melanoma, cutaneous melanoma, NSCLC, mesothelioma, myelofibrosis, and NHL.

Within Part B, up to 26 patients with metastatic uveal melanoma will be recruited to determine the monotherapy activity of IOA-244. Patients with metastatic uveal melanoma currently have no approved treatment options. Positive outcome from this part of the trial is expected to support transition to subsequent registration studies for metastatic uveal melanoma. Interim data is expected in Q2 2022 with final top-line data scheduled for Q4 2022.

"iOnctura is entering a highly exciting phase as it progresses two tumor-stroma-immune interface targeting programs through clinical development. IOA-244 continues to demonstrate an unprecedented clinical profile among PI3Kδ inhibitors," said Catherine Pickering, CEO of iOnctura. "iOnctura is moving rapidly in the use of IOA-244 to treat a range of solid tumor types including metastatic uveal melanoma, an underserved cancer with no currently approved drug treatments and poor patient outcomes. We look forward to releasing early data from our preclinical and clinical evaluations of this exceptional molecule at ESMO (Free ESMO Whitepaper) IO."

Once-failed cancer drug from BioXcel ramps up immunotherapy in mouse models of pancreatic cancer

On November 8, 2021BioXcel Therapeutics reported that it raised $60 million in an initial public offering a few years back, it said it would pour part of the proceeds into developing talabostat, a drug that failed a phase 3 trial in pancreatic cancer in 2007 (Press release, BioXcel Therapeutics, NOV 8, 2021, View Source [SID1234595336]). Now, BioXcel, along with collaborators at Georgetown University, has preclinical data suggesting the drug may boost the benefits of immunotherapy in this tough-to-treat cancer.

Georgetown researchers tested talabostat (also known as BXCL701) alone and alongside a treatment that inhibits the immune checkpoint PD-1 in mouse models of pancreatic cancer. Both treatments slowed tumor growth, and the combination significantly increased the recruitment of cancer-fighting immune cells, the researchers reported in the Journal for ImmunoTherapy of Cancer.

Talabostat works by inhibiting the protein dipeptidyl peptidase (DPP). Knowing that earlier studies had suggested the drug might improve immunotherapy, the Georgetown researchers wanted to see what would happen if they combined it with PD-1 inhibition. Checkpoint blockade has worked in many cancer types but has so far not panned out in pancreatic cancer.

They discovered that talabostat ramped up the infiltration of T cells and natural killer (NK) cells into the pancreatic tumor environment. Combining the drug with anti-PD-1 therapy not only slowed tumor growth and boosted immune activity, it also created "immune memory" in 10 out of 13 mice that had been cured by the initial therapy, allowing them to clear some tumors after they were re-exposed to pancreatic cancer months later.

The researchers believe the key to the combination’s effectiveness rested in the recruitment of NK cells, which combat cancer in two ways: They kill cancer cells directly, and they release "signaling molecules" that regulate other aspects of the immune system in ways that control tumor growth, they explained in a statement.

To back up their hunch, they studied real-world data in the National Institutes of Health’s Cancer Genome Atlas and found that increased levels of NK cells in human pancreatic tumors correlated with longer survival, the team reported.

RELATED: AACR (Free AACR Whitepaper): Attacking pancreatic cancer by thwarting its survival strategies

NK cells are of great interest to several research groups and biotechs that are searching for new approaches to treating solid tumors. Fate Therapeutics, for example, is developing an NK cell therapy that in preclinical studies killed cancer cells—including pancreatic tumor cells—when combined with anti-PD-1 therapy. The investigational product, FT500, is now in phase 1 testing in advanced solid tumors.

Other combinations designed to boost the immune response are under investigation in pancreatic cancer. Last year at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) conference, a University of Minnesota team reported that combining a PD-L1 inhibitor with a CD40 blocker in mouse models of pancreatic cancer eliminated tumors in 60% of the animals. Apexigen is testing its CD40-targeted drug in combination with Bristol Myers Squibb’s PD-1 blocker Opdivo and other therapies in pancreatic cancer and reported survival benefits over the standard of care earlier this year.

As for BioXcel, it is currently testing talabostat in combination with Merck’s blockbuster PD-1 inhibitor Keytruda in metastatic castration-resistant prostate cancer and some tumors that are resistant to immune checkpoint inhibitors.

The Georgetown researchers said they’re planning to conduct additional animal trials to better understand the mechanism of action of the talabostat-anti-PD-1 combination in pancreatic tumors. From there, they hope to design a clinical trial, they said.
