Athenex and Xiangxue Life Sciences Announce Preliminary Results of Patients Receiving T-Cell Receptor Affinity Enhancing Specific T-Cell Therapy (TAEST) Showed Encouraging Positive Clinical Signals

On October 15, 2018 Athenex, Inc. (NASDAQ:ATNX), a global biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies for the treatment of cancer and related conditions, reported that preliminary results of pilot studies in China in which patients received T-cell receptor affinity enhancing specific T-cell therapy ("TAEST") showed encouraging positive clinical signals in terms of efficacy and safety (Press release, Athenex, OCT 15, 2018, View Source;p=RssLanding&cat=news&id=2371574 [SID1234529935]).

The pilot studies are being conducted in China by Xiangxue Life Sciences ("XLifeSc"), a wholly-owned subsidiary of Xiangxue Pharmaceutical Co., Ltd. (Shenzhen Exchange: 300147). In July 2018, XLifeSc and Athenex entered into an agreement to establish a new joint venture named Axis Therapeutics Limited, which owns the global rights to the TAEST technology, excluding China (XLifeSc retains the mainland China rights), and in this territory Axis Therapeutics is leading the research, development and commercialization efforts of T-cell receptor-engineered T cells (TCR-T, including the TAEST technology), a form of cancer immunotherapy.

The pilot studies are focused on the testing of TAEST technology generated T-cells, with enhanced binding affinity, against the antigen NY-ESO-1 and is HLA-A*02:01 restricted. Preliminary results of TAEST technology generated T-cell therapy studied in nine end-stage cancer patients who failed all standard treatments showed the following: In the first three patients, dose escalation in one patient and full dose in two patients were tested. All three patients showed an acceptable safety profile. Two of the patients showed stable disease with survival of 6 and 10 months, respectively. One patient with lung cancer showed a small tumor reduction, and a reduction in pain and softening of the subcutaneous metastasis following treatment. Lymphodepletion was added to the protocol in patients 4 through 9. Treatment was well tolerated with fever (n=5), chills (n=4), weakness (n=4), and mild skin rash (n=3) observed. Two patients (one breast cancer, one synovial sarcoma) had more than 40% reduction in tumor size, as measured by CT scans. The patient with breast cancer also had healing of two skin metastatic ulcers. Two other patients (one liver cancer patient with retroperitoneal recurrence after resection, one with thyroid cancer) showed stable disease. Both of these patients showed significant tumor necrosis shortly after the treatment, resulting in the formation of cavitation in the middle of the tumors. Clinically, there was also symptomatic relief of local pain reported during the period of radiologic evidence of increased tumor necrosis. The remaining two patients with lung cancer had stable disease for more than 60 days after treatment. This study also observed the expected cytokine response, detection of TCR-expression on T-cells, and persistence of the introduced TCR-gene in all patients during therapy.

An abstract with more detailed data will be submitted for presentation at an international scientific meeting.

Dr. Yi Li, Chief Scientific Officer of Axis Therapeutics and XLifeSc, stated, "We believe our TAEST technology has four distinct advantages: first, our engineered TCR has an improved binding affinity; second, our engineered TCR has excellent expression level on the engineered T-cells; third, we have demonstrated in this pilot study that our engineered TCR genes persisted in these patients; and finally, we have developed other HLA subtypes and we will be able to treat more patients with different HLA subtypes in the near future."

Dr. Johnson Lau, Vice Chairman and CEO of Axis Therapeutics and Chairman and CEO of Athenex, said, "We are excited by the positive clinical signal observed in this group of patients. The safety profile is within expectations and within acceptable limits of cancer therapy. The observation of clinical signal in these patients, with tumor reduction of more than 40% in two patients and significant tumor necrosis after treatment in two others, indicates that this approach showed anti-tumor activity even in late stage cancer patients. We have also followed the circulating level of the engineered T-cells and inserted gene expression and so far, their persistence in the patients’ circulation suggested that this approach can have the desired effect of having a consistent anti-tumor immune response for at least a moderate amount of time. More work will be done soon to define the best treatment protocol to advance this program. We are very grateful to Perceptive Advisors for their support and confidence in our team which made this joint venture possible."

Mr. YongHui Wang, Chairman of Axis Therapeutics and Chairman and CEO of Xiangxue Pharmaceutical, stated, "We are very impressed by the scientific and management skills that Athenex team contributes to this joint venture. We are excited to see these encouraging preliminary clinical data. We have full confidence in our collaboration and strongly believe that we will make a meaningful contribution to the arsenal of cancer treatment options for patients worldwide."

Axis Therapeutics is also announcing the line-up of the management team, with Mr. YongHui Wang as the Chairman of the Board, Dr. Johnson Lau as Vice-Chairman and CEO, Dr. Yi Li as Chief Scientific Officer, Dr. WingKai Chan as Chief Medical Officer, and Ms. Jacqueline Li as the Chief Financial Officer.

About Sitravatinib

Sitravatinib is a spectrum-selective kinase inhibitor that potently inhibits receptor tyrosine kinases (RTKs), including TAM family receptors (TYRO3, Axl, Mer), split family receptors (VEGFR2, KIT) and RET. As an immuno-oncology agent, sitravatinib is being evaluated in combination with nivolumab (OPDIVO), an anti-PD-1 checkpoint inhibitor, in patients who have experienced documented disease progression following treatment with a checkpoint inhibitor. Sitravatinib’s potent inhibition of TAM and split family RTKs may overcome resistance to checkpoint inhibitor therapy through targeted reversal of an immunosuppressive tumor microenvironment, enhancing antigen-specific T cell response and expanding dendritic cell-dependent antigen presentation.

Sitravatinib is also being evaluated as a single agent in a Phase 1b expansion clinical trial enrolling patients whose tumors harbor specific mutations in the CBL kinase. When CBL is inactivated by mutation, multiple RTKs, including TAM, VEGFR2 and KIT, are dysregulated and may act as oncogenic tumor drivers in NSCLC and melanoma. Sitravatinib potently inhibits these RTKs and is being investigated as a treatment option for cancer patients with CBL mutations

"Following the positive interim results reported in July 2018 from this ongoing Phase 1b/2 study evaluating AU-011 in patients with choroidal melanoma, we are pleased to be sharing these updated, one-year results with the medical community at AAO this year," said Elisabet de los Pinos, Ph.D., Founder and Chief Executive Officer of Aura. "There are no FDA approved therapies for the treatment of choroidal melanoma, the most common type of primary eye cancer. Patients are currently treated with radiotherapy and surgery which typically results in severe vision loss, along with a plethora of other severe adverse effects and comorbidities. If approved, AU-011 will be the first targeted therapy for the treatment of choroidal melanoma, with the potential to preserve vision and transform the treatment paradigm for these patients."

In addition to the AAO clinical data presentations, Aura has been selected to present its innovative technology for the treatment of choroidal melanoma as part of the Innovation Showcase during the Ophthalmology Innovation Summit (OIS@AAO) taking place Thursday, October 25, 2018, at the Marriot Marquis Chicago. Dr. de los Pinos will give the presentation which will provide an update on Aura Biosciences.

About Choroidal Melanoma

Choroidal melanoma is a rare and aggressive type of eye cancer. Choroidal melanoma is the most common primary ocular tumor and develops in the uveal tract of the eye. No targeted therapies are available at present, and current radiotherapy treatments can be associated with severe visual loss and other long-term sequelae such as dry eye, glaucoma, cataracts and radiation retinopathy. The most common current treatment is plaque radiotherapy, which involves surgical placement of a radiation device on the exterior of the eye over the tumor. The alternative is enucleation, or total surgical removal of the eye. Choroidal melanoma metastasizes to the liver in about 40-50 percent of cases in the long term (source: OMF), and only 15 percent of patients whose melanoma has metastasized survive beyond five years after diagnosis (source: ACS).

About Light-Activated AU-011

AU-011 is a first-in-class targeted therapy in development for the primary treatment of choroidal melanoma. The therapy consists of proprietary viral-like particle bioconjugates (VPB) that are activated with an ophthalmic laser. The VPBs bind selectively to unique receptors on cancer cells in the eye and are derived from technology originally pioneered by Dr. John Schiller of the Center for Cancer Research at the National Cancer Institute (NCI), recipient of the 2017 Lasker-DeBakey Award. Upon activation with an ophthalmic laser, the drug rapidly and specifically disrupts the cell membrane of tumor cells while sparing key eye structures, which may allow for the potential of preserving patients’ vision and reducing other long-term complications of radiation treatment. AU-011 can be delivered using equipment commonly found in an ophthalmologist’s office and does not require a surgical procedure, pointing to a potentially less invasive, more convenient therapy for patients and physicians. AU-011 for the treatment of choroidal melanoma has been granted orphan drug and fast track designations by the U.S. Food and Drug Administration and is currently in clinical development.
