In the research presented, Pathios evaluated the impact of PTT-3196, an orally bioavailable, potent and selective GPR65 inhibitor, on expression of key immune-related genes and tumor growth in a highly glycolytic RCC PDX model implanted in NCG mice that had been reconstituted with human immune cells. The key findings of the study were:

A dose-dependent increase in a host of genes known to be predictive of a successful response to T cell checkpoint inhibitors in the clinic including CD3D, CD3E, IL2RG, CCL5 and CXCl10
Prominent increases in a range of other genes comprising a Type I/II interferon signature including CD40, STAT1, TAP1, TAP2 and components of the inducible immunoproteasome (PSMB8, PSMB9 and PSMB10)
A reduction in tumor volume commensurate with the gene expression changes highlighted above
A suppression of pro-tumorigenic genes including TGFB, IL10 and ADORA2A
"We are extremely excited about these results. PTT-3196 is able to robustly activate the human innate immune system in a highly glycolytic, patient derived tumor microenvironment, reversing many of the pro-tumorigenic macrophage gene expression changes that result from chronic exposure to an acidic environment. The ability to bring about a gene expression signature that is predictive of clinical success with T cell checkpoint inhibitors is especially encouraging and fully validates the concept that GPR65 inhibitors counteract a critical innate immune checkpoint that we believe prevents the majority of solid cancers being able to respond to currently approved immunotherapies." Stuart Hughes, Chief Executive Officer of Pathios Therapeutics

On July 7, 2021 ViewRay, Inc. (NASDAQ: VRAY) reported that the Miami Cancer Institute, part of Baptist Health South Florida, has enrolled the first patients in its "Stereotactic MRI-guided Adaptive Radiation Therapy (SMART) in One Fraction for Inoperable Primary or Metastatic Carcinoma" clinical study – referred to as the SMART ONE trial (NCT#04939246) (Press release, ViewRay, JUL 7, 2021, View Source [SID1234584675]). This single-arm prospective study that was developed and led by Dr. Michael Chuong, MD, FACRO, radiation oncologist and Medical Director of Proton Therapy and MR-guided Therapy at Miami Cancer Institute, is exploring the feasibility and tolerability of single-fraction stereotactic ablative body radiation therapy (SABR) for primary or metastatic carcinoma involving the lung, liver, adrenal gland, abdominal/pelvic lymph node, pancreas, and kidney.*

The use of MRI instead of CT for daily image guidance offers several important advantages in the delivery of SABR including superior visualization of the internal anatomy prior to and uniquely continuously during treatment delivery.

SABR is an advanced and technically complex procedure in which very high radiation dose is delivered using steep dose gradients with millimeter precision and accuracy. The most common delivery schedule is daily treatment for five total days to each targeted tumor. While completing treatment in only one day may be possible, it is not commonly done using CT-guided radiation delivery machines because of safety concerns due to limitations in visual confirmation of tumor and nearby critical organ position throughout treatment.

MRIdian’s design allows clinicians the ability to safely deliver an ablative dose and expand single-fraction SABR to tumors that would not have been previously considered. The design includes diagnostic-quality anatomic imaging prior to treatment delivery, the ability to perform on-table adaptive planning and continuous intrafraction visualization, soft tissue tracking and automatic beam gating. These features facilitate tighter planning target volume margins to spare healthy tissue, especially in immediate proximity to the target, which allow for reduction or elimination of higher-grade toxicities often associated with SABR dose delivery.

"With MRIdian, we’re giving clinicians the clinical confidence to safely deliver ablative radiation doses while also reducing the number of treatments," said Martin Fuss, M.D., chief medical officer at ViewRay. "MRI-guidance and on-table adaptive delivery ensure that these powerful radiation doses are reaching the target but avoid highly sensitive surrounding critical structures. We believe this treatment concept has the potential to alleviate toxicity risks associated with SABR while improving outcomes for cancer patients around the world."

A growing body of clinical literature has led to the initiation of the SMART ONE trial design. This evidence describes favorable outcomes of image-guided SABR for various cancers, including tumors in the pancreas, liver, lung, breast, adrenal gland, kidney, lymph nodes, and prostate; however, the peer-reviewed, published body of data has nearly exclusively been based on multi-fraction SABR.

"Published experience suggests that delivery of single-fraction SABR using MRIdian should be at least isotoxic and isoeffective as compared to multi-fraction SABR, as supported by its on-table adaptive planning capabilities and continuous soft-tissue tracking with automatic beam gating," said Dr. Chuong. "We believe the study will demonstrate the feasibility to safely and effectively deliver SABR in only one fraction across these indications that will not only shorten overall treatment time, but also reduce cost and improve increase patient convenience."

The MRIdian system provides oncologists outstanding anatomical visualization through diagnostic-quality MR images and the ability to adapt a radiation therapy plan to the targeted cancer with the patient on the table. This combination allows physicians to define tight treatment margins to avoid unnecessary radiation exposure of vulnerable nearby organs-at-risk and allows the delivery of ablative radiation doses in five or fewer treatment sessions, without relying on implanted markers. By providing real-time continuous tracking of the target and surrounding healthy tissues, MRIdian enables automatic gating of the radiation beam if the target moves outside the user-defined margins. This allows for delivery of the prescribed dose to the target, while sparing surrounding healthy tissue and critical structures, which results in minimizing toxicities typically associated with conventional radiation therapy.

More than 12,500 patients have been treated with MRIdian. Currently, 44 MRIdian systems are installed at hospitals around the world where they are used to treat a wide variety of solid tumors and are the focus of numerous ongoing research efforts. MRIdian has been the subject of hundreds of peer-reviewed publications, scientific meeting abstracts, and presentations. For a list of treatment centers, please visit: View Source
