On March 30, 2022 Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer and infectious diseases, reported the initiation of a Phase 1 trial evaluating its novel chimeric antigen receptor T-cell (CAR-T) therapy in ovarian cancer (Press release, Anixa Biosciences, MAR 30, 2022, View Source [SID1234611211]). The CAR-T approach used for Anixa’s therapy is known as chimeric endocrine receptor T-cell (CER-T) since the target of the engineered T-cells is an endocrine receptor. The Phase 1 trial at Moffitt Cancer Center will evaluate the safety and efficacy of Anixa’s therapy in patients with ovarian cancer. Anixa holds an exclusive, worldwide license for the technology, which was developed at the Wistar Institute.

While CAR-T therapy has shown efficacy in some hematological tumors, reproducing the same results with solid tumors, such as ovarian cancer, has proven challenging. One of the reasons for this difficulty is that effective CAR-T therapy needs a specific antigen to recognize that is only present on target cancer cells in order to avoid negatively affecting healthy cells. The CER-T therapy being evaluated in Anixa’s Phase 1 study differs from traditional CAR-T in that it targets the follicle stimulating hormone receptor (FSHR), which research indicates is exclusively expressed on ovarian cells in healthy adult females.

"We are thrilled to have partnered with world-class scientists at Moffitt Cancer Center to advance our CER-T platform and feel that this partnership provides a critical opportunity to make a significant impact on the treatment of solid tumors," said Dr. Amit Kumar, President, CEO and Chairman of Anixa Biosciences. "We strongly believe that our unique targeting approach differentiates our CER-T platform from traditional CAR-T approaches and that CER-T has potential to work in solid tumors where other therapies have failed."

Jose R. Conejo-Garcia, M.D., Ph.D., Chair of the Department of Immunology at Moffitt Cancer Center and co-inventor of the CER-T technology, added, "CAR-T therapies are rapidly becoming an important player in cancer therapy, and our lab has developed a technology that has the potential to target tumors by using an existing biological mechanism that is well understood. If our CER-T approach is successful, it could serve as a model for future targeted CAR-T therapies in other cancer types. The goal in cancer therapy has always been to kill cancer cells with limited damage to healthy tissue, and we look forward to seeing how this CER-T therapy may be able to accomplish that in solid tumors, which have historically proven challenging to eradicate with cell therapy."

Robert Wenham, M.D., MS, FACOG, FACS, the trial’s lead investigator and Chair of the Department of Gynecologic Oncology at Moffitt Cancer Center, added, "There are limited treatment options for recurrent, chemo-resistant ovarian cancer, and this platform holds immense promise to change that. I am hopeful that this program represents a unique opportunity for us to potentially make a truly game-changing impact for patients with ovarian cancer and other solid tumors."

About Anixa’s CER-T Approach (Follicle Stimulating Hormone Receptor-Mediated CAR-T technology)
Anixa’s chimeric antigen receptor T-cell (CAR-T) technology approach is an autologous cell therapy comprised of engineered T-cells that target the follicle stimulating hormone receptor (FSHR). FSHR is found at immunologically relevant levels exclusively on the granulosa cells of the ovaries. Since the target is a hormone (chimeric endocrine) receptor, and the target-binding domain is derived from its natural ligand, this technology is known as CER-T (chimeric endocrine receptor T-cell) therapy, a new type of CAR-T.

On March 30, 2022 Sutro Biopharma, Inc. ("Sutro" or the "Company") (NASDAQ: STRO), a clinical-stage drug discovery, development and manufacturing company focused on the application of precise protein engineering and rational design to create next-generation cancer therapeutics, reported that the company presented on advances with its novel immunostimulatory antibody-drug conjugate (iADC) modality at the 12th Annual World ADC conference taking place virtually and in London, from March 29 through April 1, 2022 (Press release, Sutro Biopharma, MAR 30, 2022, View Source [SID1234611210]).

Sutro’s novel iADC modality was generated with Sutro’s proprietary and integrated cell-free protein synthesis platform and site-specific conjugation platform. The molecule allows for a single therapy to target tumors with conjugated toll-like receptor (TLR) agonist in addition to a conjugated cytotoxic warhead. The iADC modality provides for dual mechanisms to attacking the tumor, through cytotoxic killing as well as potentially building a protective immune response. Using dual conjugations to deliver both components as systemic therapy potentially broadens the types of tumors that can be treated.

"This novel iADC modality is a further confirmation of the fruitful journey at Sutro, building upon a decade of research working with precisely conjugated ADCs," commented Trevor Hallam, Ph.D., President of Research and Chief Scientific Officer of Sutro. "Sutro’s novel iADC technology has therapeutic potential in difficult-to-treat cancers by both directly targeting cancer cells and activating the patient’s own immune system through the dual mechanism of action. With this technology, we can potentially develop an off-the-shelf therapy that aims to program a patients natural immune response to treat cancer and protect against future disease."

Dr. Hallam presented virtually at a session during the pre-conference seminar titled, "A New Molecular Class to target Tumor Immunity by both disrupting the tumor and enabling the immune system" on Tuesday, March 29, 2022.

Arturo Molina, M.D., M.S., FACP, Chief Medical Officer of Sutro, presented a session titled "Targeting FolRα in Gynecologic Cancers & other Solid Tumours with the Novel Antibody-Drug Conjugate, STRO-002," on Wednesday, March 30. The talk examined nonclinical and clinical data of STRO-002 in ovarian, endometrial, and other cancers, including the previously disclosed interim dose-expansion data of STRO-002-GM1.

The presentations will be accessible through the News & Events page of the company’s website at www.sutrobio.com.

On March 30, 2022 Everest Medicines (HKEX 1952.HK), a biopharmaceutical company focused on developing and commercializing transformative pharmaceutical products to address critical unmet needs in Asia Pacific markets, reported that it has submitted a New Drug Application (NDA) to the Department of Health, the Hong Kong Special Administrative Region, China for sacituzumab govitecan (SG) for the treatment of unresectable locally advanced or metastatic triple-negative breast cancer (mTNBC) in adult patients who have received two or more prior systemic therapies, at least one of them for metastatic disease (Press release, Everest Medicines, MAR 30, 2022, View Source [SID1234611209]).

"This submission reinforces the ongoing momentum in the development of SG throughout Asia, bringing this medicine one step closer to patients in yet another important region in Asia, and adding to the growing number of regulatory applications under active review," said Yang Shi, Chief Medical Officer for Oncology at Everest Medicines. "As women diagnosed with mTNBC have historically had minimal treatment options available to them and breast cancer has become the most common cause of death in women in Hong Kong over the past few decades, this application is especially timely. We look forward to moving closer to our goal of making SG an accessible treatment option for women throughout Greater China."

Everest is also closely coordinating with regulatory bodies in mainland China, South Korea and Taiwan to review its applications for SG for adult patients with unresectable locally advanced or mTNBC who have received two or more prior systemic therapies, at least one of them for metastatic disease. In February 2022, Everest announced the approval of Trodelvy (trade name for SG) in Singapore for second-line mTNBC.

In November 2021, Everest announced topline results for its Phase 2b EVER-132-001 study of SG, which met its primary endpoint with a 38.8% overall response rate (ORR). This study evaluated 80 people in China, and the results were consistent with those from the global Phase 3 ASCENT study, thus showing similar efficacy in the Chinese population.

About Triple-Negative Breast Cancer (TNBC)

TNBC is the most aggressive type of breast cancer and accounts for approximately 15% of all breast cancers. The median age of breast cancer diagnoses tends to be younger in Asian than western countries, and the percentage of the TNBC molecular subtype has been increasing in the past 10 years. TNBC cells do not have estrogen and progesterone receptors and have limited human epidermal growth factor receptor 2 (HER2). Due to the nature of TNBC, effective treatment options are extremely limited compared with other breast cancer types. TNBC has a higher chance of recurrence and metastases than other breast cancer types. The average time to metastatic recurrence for TNBC is approximately 2.6 years compared with 5 years for other breast cancers, and the relative five-year survival rate is much lower. Among women with metastatic TNBC, the five-year survival rate is 12%, compared with 28% for those with other types of metastatic breast cancer.

About Sacituzumab Govitecan (SG)

Sacituzumab govitecan (SG) is a first-in-class Trop-2 directed antibody-drug conjugate. Trop-2 is a cell surface antigen highly expressed in multiple tumor types, including in more than 90% of breast and bladder cancers. SG is intentionally designed with a proprietary hydrolyzable linker attached to SN-38, a topoisomerase I inhibitor payload. This unique combination delivers potent activity to both Trop-2 expressing cells and the microenvironment.

SG is approved in more than 35 countries, with additional regulatory reviews underway worldwide, for the treatment of adult patients with unresectable locally advanced or metastatic TNBC, under the trade name Trodelvy. SG is also approved in the U.S. under the accelerated approval pathway for the treatment of adult patients with locally advanced or metastatic urothelial cancer (UC) who have previously received a platinum-containing chemotherapy and either programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor.

SG is also being developed for potential investigational use in other TNBC and metastatic UC populations, as well as a range of tumor types where Trop-2 is highly expressed, including hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) metastatic breast cancer, metastatic non-small cell lung cancer (NSCLC), metastatic small cell lung cancer (SCLC), head and neck cancer, and endometrial cancer.

Under a licensing agreement with Gilead Sciences, Inc., Everest Medicines has exclusive rights to develop, register, and commercialize SG for all cancer indications in Greater China, South Korea, and certain Southeast Asian countries. In October 2020, SG was included in the updated 2020 China Guidelines for the Standardized Diagnosis and Treatment of Advanced Breast Cancer, compiled by the Breast Cancer Expert Committee of the National Cancer Control Center, the Breast Cancer Professional Committee of the Chinese Anti-Cancer Association, and the Cancer Drug Clinical Research Professional Committee of the Chinese Anti-Cancer Association.

On March 30, 2022 CStone Pharmaceuticals ("CStone", HKEX: 2616), a leading biopharmaceutical company focused on the research, development, and commercialization of innovative immuno-oncology therapies and precision medicines, reported that the first patient has been enrolled in the U.S. in the Phase 1 clinical trial for CS5001 (Press release, CStone Pharmaceauticals, MAR 30, 2022, View Source [SID1234611208]).

CS5001 is a potential global best-in-class antibody-drug conjugate (ADC), targeting receptor tyrosine kinase-like orphan receptor 1 (ROR1). As one of the three most advanced ROR1 ADCs worldwide, CS5001 has been approved for the initiation of a multi-regional clinical trial in the US and Australia. The China National Medical Products Administration (NMPA) has accepted the investigational new drug (IND) application of CS 5001. This first-in-human Phase 1 study aims to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity of CS5001 in advanced B cell lymphomas and solid tumors.

ROR1 is an oncofetal protein with low or no expression in adult tissues but high expression in a variety of cancers including various forms of leukemia and non-Hodgkin lymphoma, breast, lung, and ovarian cancers, making it an ideal ADC target. Results from pre-clinical studies showed that CS5001 exhibited potent and selective cytotoxicity to a variety of ROR1-expressing cancer cell lines and demonstrated remarkable in vivo antitumor activity in both hematological and solid tumor xenograft models. The preclinical data were presented as a late-breaking abstract at the 33rd AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) 2021.

Dr. Archie Tse, Chief Scientific Officer of CStone, said: "We are very glad to have the first patient enrolled in the first-in-human study of CS5001. This potentially best-in-class ROR1 ADC contains a number of differentiated features which may translate into a wider therapeutic window against a variety of cancer types — a fully human antibody backbone, proprietary site-specific conjugation, and tumor-cleavable linker and prodrug technology. Results from the preclinical studies of CS5001 already showed its therapeutic potential in ROR1-expressing hematological and solid malignancies. We will swiftly execute the global development program of CS5001, starting with this Phase 1 study to characterize its safety and preliminary efficacy in the treatment of advanced B-cell lymphoma and selected solid tumors."

About CS5001（ROR1 ADC）

CS5001 is a clinical-stage antibody-drug conjugate (ADC) targeting ROR1 (receptor tyrosine kinase-like orphan receptor 1). CS5001 has uniquely designed and LCB’s proprietary tumor-cleavable linker and pyrrolobenzodiazepine (PBD) prodrug. Only after reaching the tumor, the linker and prodrug are cleaved to release the PBD toxin, resulting in lethal DNA cross-links in cancer cells. The use of the linker plus PBD prodrug effectively helps addressing the toxicity problem associated with traditional PBD payloads, leading to a better safety profile. Additionally, CS5001 utilizes site-specific conjugation for a precise drug antibody ratio of 2 which enables homogeneous production and large-scale manufacturing.

In October 2020, CStone signed a licensing agreement with LegoChem Biosciences, Inc. (LCB) for the development and commercialization of CS5001 which was originally generated by collaboration of LCB and ABL Bio, both South Korea-based leading biotech companies. Under the agreement, CStone obtains the exclusive global right to lead development and commercialization of CS5001 outside the Republic of Korea.
