"We are excited for achieving this important milestone, which also marked the first step to what we hope will ultimately allow us to bring an innovative cancer immunotherapy to patients who otherwise do not respond to or become relapsed/refractory of current therapies", said Dr. Liusong Yin, the Executive President and Chief Science Officer of SunHo, "We focus on innovative immunocytokines to build the next leading global biopharma of immunotherapy, and to bring perceivable benefits and affordable medicine to patients worldwide, by innovation and collaboration."

About IAP0971

IAP0971 is the world’s first PD1-IL15 immunocytokine receiving IND approval from both FDA and NMPA. It was developed by SunHo based on their own proprietary and patented AICTM (Armed ImmunoCytokine) platform.

SunHo designed IAP0971 based on the deep understanding of the tumor microenvironment and limitations of current immunotherapy. On the one hand, IL15/IL15Rα complex in IAP0971 specifically binds to the IL2/15Rβ and IL2/15Rγ expressed on T cells and NK cells and promotes the proliferation and activation of T cells and NK cells, without activation of Treg cells or inducing apoptosis of activated T cells which are common side effects of IL2-based therapies. On the other hand, the expression of PD1 on CD8+ T cells in tumor microenvironment is much higher than that in peripheral blood and peripheral lymphoid organs, so that anti-PD1 antibody in IAP0971 can specifically target IL15 into the tumor immune microenvironment, to recruit, activate and reinvigorate immune cells, and achieve a much-enhanced anti-tumor immunity. IAP0971 fuses the anti-PD1 antibody and IL15 cytokine, acts in the same location and on the same cells at the same time showing great cis-synergy, which will further improve the effectiveness and therapeutic window of IAP0971.

The indications of IAP0971 include lung cancer, cervical cancer, head and neck squamous cell carcinoma, liver cancer, lymphoma, and other locally-advanced or metastatic malignant tumors.

About IAE0972

IAE0972 is the world’s first EGFR-IL10 immunocytokine receiving IND approval from both FDA and NMPA. It was also developed by SunHo based on their own proprietary and patented AICTM (Armed ImmunoCytokine) platform.

IAE0972 was designed to solve the problems of immune cell exhaustion in current immunotherapy, and to lift the limitations of current EGFR-based monoclonal antibodies. IL10 in IAE0972 is a potent activator of antigen-specific CD8+ T cells in the tumor microenvironment and can restore the tumor-killing activity of tumor-infiltrating lymphocytes by restoring the oxidative phosphorylation metabolism of Terminally Exhausted T cells. Anti-EGFR antibody can specifically enrich IAE0972 in tumor microenvironment, so that IL10 can reinvigorate antigen specific CD8+ T cells and facilitate its proliferation, while preserving the tumor cell proliferation inhibition activities of EGFR antibody. Relying on the synergy of EGFR antibody and IL10 cytokine, IAE0972 can effectively and specifically activate the immune system to kill EGFR-positive tumor cells, solving the drug resistance, high skin toxicities, and other clinical problems of existing drugs.

The indications of IAE0972 include colorectal cancer, head and neck squamous cell carcinoma, squamous non-small cell lung cancer, and other locally advanced or metastatic malignant tumors.

On July 7, 2022 RefleXion Medical, a therapeutic oncology company pioneering the use of biology-guided radiotherapy (BgRT)* for all stages of cancer, reported a non-exclusive, worldwide licensing agreement with Mirada Medical (Press release, RefleXion Medical, JUL 7, 2022, View Source [SID1234616549]). The agreement allows for the integration of Mirada’s RegEngine image registration algorithms into the RefleXion X1 treatment planning software. The algorithms align patient anatomy between different imaging modalities or between radiotherapy treatments.

"Day-of-treatment modifications, called adaptive radiotherapy, are critical for responding to changes in patient anatomy that occur as a result of cancer treatment, and to lowering toxicity to improve outcomes," said Thorsten Melcher, Ph.D., chief business officer at RefleXion. "In challenging patients, such as those with metastatic disease where more than one tumor may be treated, adaptation requires robust tools such as Mirada’s sophisticated RegEngine software, so that clinicians can quickly assess patient anatomy and, in the future their biology, to implement changes to the treatment plan.

"Mirada’s extensive industry experience and development expertise were key factors in our decision to pursue this agreement," continued Melcher.

Image registration is a complex series of algorithms that align the images of a patient’s anatomy taken at different points in time and using different imaging modalities. For radiation oncology, where millimeters matter in order to preserve healthy tissue, registration of the tumor target to be treated, as well as nearby anatomy to avoid, is critical. Precise targeting may also result in lowering toxicity, thereby improving outcomes for patients.

BgRT is designed to one day overcome the technical limitations of existing radiotherapy approaches by using a PET radiotracer to create a unified motion management solution for one or multiple tumors. As the PET tracer binds to tumor cells, it produces emissions that signal the cancer’s location. BgRT uses this real-time biological information to deliver a tracked radiation dose to the cancer. Integrating RegEngine into BgRT will allow clinicians to rapidly adapt the daily treatment plan by precisely registering images and image components crucial for treatment planning and dose calculation.

A difficult challenge occurs when the frames of reference of the images are similar, but the patient’s anatomy has changed from biological processes, such as breathing or digestion, or changes in position during the imaging procedures. To assist clinicians in accounting for these changes, RegEngine "warps" or "deforms" the images pixel by pixel, a process called deformable image registration.

"Our relationship with RefleXion is another example of our ability to work with cutting edge oncology companies," said Jon DeVries, CEO at Mirada. "RefleXion’s biology-guided radiotherapy has the potential to offer a new treatment option for patients with all stages of cancer, and we are excited and proud to have RegEngine selected as a key component of the treatment planning process in this exciting novel technology."

The new Mercy Proton Therapy Center is one of only 40 treating centers in the U.S. Thanks to the compact size of the MEVION S250i, Mercy was able to integrate the addition into the existing radiation oncology department, enabling the hospital to share existing resources and maintain a full continuum of care for patients.

A ribbon-cutting event was held on June 30 with members from Mercy and Mevion Medical Systems.

"We know patients have choices when it comes to cancer care and when they choose Mercy, we want them to know they have access to all the options for care," said Dr. Robert Frazier, division chief of radiation oncology at Mercy Hospital St. Louis. "Each patient is unique so no two treatment plans will be the same. At the David C. Pratt Cancer Center, we now have all the most advanced radiation therapy technologies, both Cyberknife and proton therapy, making sure we offer what’s best for each individual during their cancer therapy."

The center features Mevion’s industry-leading HYPERSCAN pencil beam scanning technology and Adaptive Aperture pMLC. The powerful duo delivers faster and more precise, therapeutic doses of radiation to tumors while preserving surrounding healthy tissue and organs at risk, making proton therapy an ideal treatment choice for tumors near sensitive parts of the body such as the head and neck, spinal cord, breasts, esophagus, prostate, lung, bone, gastrointestinal, stomach, colon, and bladder.

The MEVION S250i system at Mercy also integrates the CBCT imaging system and the C-RAD Catalyst PT surface-guided tracking system, enabling a cutting-edge Image-Guided Proton Therapy configuration for high-precision patient positioning and intra-fraction motion management.

"We congratulate Mercy for starting treatment with the Mevion proton therapy system," said Tina Yu, chief executive officer and president of Mevion Medical Systems. "Mevion is proud to be a part of Mercy’s dedication to offering this state-of-the-art cancer treatment in St. Louis and the surrounding area."

Mevion is the system provider for 60% of the clinical single-room proton centers in the U.S. and has treated over 7,000 patients worldwide.
