When paired with the screening mammogram, SoftVue has been shown to identify up to 20 percent more cancers in women with dense breasts while also reducing false positives and decreasing unnecessary call-backs and biopsies.

"SoftVue is a game-changer that will transform clinical practice with a new and highly impactful whole breast ultrasound adjunctive screening modality that will help save lives by identifying cancer sooner for women with dense breasts," said Mark J. Forchette, president and chief executive officer at Delphinus. "We are seeing significant interest and enthusiasm from leading health centers across the country for SoftVue, who see the value of our technology can bring to delivering the best care for patients. To date, SoftVue has been installed at Detroit’s Barbara Ann Karmanos Cancer Institute, and at the East Alabama Medical Center. We are thrilled to be at RSNA this year and look forward to demonstrating SoftVue to radiologists attending the conference."

Also at the RSNA meeting, Dr. Mary Yamashita of the University of Southern California’s Keck School of Medicine will present the results of a study, "Density Awareness: Do Patients Know About Breast Density," showing that a large number of women are not aware of their breast density. Dr. Yamashita’s presentation is scheduled for Nov. 28 at 12:15 p.m. at the McCormick Place exhibition center.

Dense breast tissue (fibrous tissue that can hide cancerous lesions on mammogram) is common, affecting 40 percent of women and making them four times more likely to develop breast cancer. Compounding the increased risk, dense breast tissue, like cancer, typically appears white on a mammogram, making it more challenging to detect cancer early.

SoftVue was developed to address the unmet clinical need for early breast cancer detection in individuals with dense breast tissue and provides a new annual screening solution for this population. The system identifies more cancers, with fewer callbacks, using a proprietary TriAD (Triple Acoustic Detection) technology that effectively characterizes tissue by recording reflection, speed and direction of sound waves moving through breast tissue, unlike traditional ultrasound which utilizes only reflection.

On November 18, 2022 Adaptimmune Therapeutics plc (NASDAQ: ADAP), a leader in cell therapy to treat cancer, reported that clinical and translational data from the final analyses of the pivotal SPEARHEAD-1 trial (Cohort 1) with afamitresgene autoleucel (afami-cel) in patients with advanced synovial sarcoma or myxoid/round cell liposarcoma (MRCLS) at the Connective Tissue Oncology Society (CTOS) annual meeting taking place this week in Vancouver, BC (Press release, Adaptimmune, NOV 18, 2022, View Source [SID1234624248]). The data will be shared in an oral presentation by SPEARHEAD-1 investigator, Brian A. Van Tine, MD, PhD, Washington University School of Medicine in St. Louis, on Friday, November 18th, during Session 9: Immunology & Immunotherapy at 4:39 p.m. UTC/ 7:30 p.m. EST (Paper 61).​

"With these results, we continue our excitement and optimism about the clear potential of afami-cel to address synovial sarcoma- a difficult-to-treat cancer with high unmet need," said Elliot Norry, Chief Medical Officer, Adaptimmune. "These data reaffirm our commitment to this therapy, and we are very pleased to be able to include these data in our upcoming BLA submission."

Data reinforce clinical efficacy and acceptable safety profile of Adaptimmune’s novel T-cell therapy, afami-cel (August 29, 2022 data cut)

Data continue to support BLA submission for afami-cel in heavily pre-treated patients with synovial sarcoma with an overall response rate of 38.6% by independent review (N=44)
Responses are durable with a median duration of 50 weeks (range: 11.7-122 weeks)
Toxicities include cytokine release syndrome and reversible hematologic toxicities, in line with previous findings indicating an acceptable safety profile
Responses were observed across all evaluated subpopulations​ with higher response rates observed in female patients and those who had higher MAGE-A4 expression, had lower disease burden at baseline, or did not require bridging therapy. Data are consistent with those presented earlier this year as ASCO (Free ASCO Whitepaper)
Translational data indicate that afami-cel drives tumor infiltration of activated and proliferative cytotoxic ("killer") T-cells, shifting the balance from immune-suppressive to a pro-immune in the tumor microenvironment which likely contributes to antitumor response
"We are on the cusp of an exciting and important time for people impacted by synovial sarcoma, a cancer that for much too long has not seen innovative treatment options," said Dr. Brian A. Van Tine, Professor of Medicine and Pediatrics at Washington University School of Medicine in St. Louis. "The SPEARHEAD-1 Trial results provide us a reason to be very optimistic about the game-changing potential to treat more people with this difficult cancer in the very near future."

As previously announced, Cohort 1 of the SPEARHEAD-1 trial has completed treatment and met the primary endpoint for efficacy. Data from Cohort 1 will be used to support Adaptimmune’s BLA submission. Cohort 2 of the SPEARHEAD-1 trial is ongoing with treatment 60% complete and an overall response rate nearly identical to Cohort 1. On September 28th, Adaptimmune received the Vision of Hope Award from the Sarcoma Foundation of America at its Annual Stand Up to Sarcoma Gala.

SPEARHEAD-1 trial design
SPEARHEAD-1 is a Phase 2, open-label trial for people with advanced synovial sarcoma or MRCLS to evaluate the efficacy, safety, and tolerability of afami-cel. Afami-cel SPEAR T-cells target MAGE-A4+ tumors. MAGE-A4 is highly expressed in synovial sarcoma and MRCLS in the context of HLA-A*02. Compelling clinical responses in patients with synovial sarcoma were previously reported with afami-cel in a Phase 1 trial (CTOS 2020). Approximately 90 patients are planned to be treated: 45 in Cohort 1 and 45 in Cohort 2. Enrollment in Cohort 1 is complete, and Cohort 2 is currently recruiting. The primary efficacy analysis will be for Cohort 1 only and will be used to support a BLA filing, which is expected to be initiated in Q4 2022.

No formal hypothesis testing is planned for Cohort 2. Cohort 2 will strengthen the efficacy and safety database and will aid in descriptive sub-group analyses. Key eligibility criteria: ECOG performance status of 0 or 1; HLA*02 positive with MAGE-A4 expression in ≥ 30% of tumor cells ≥ 2+ by immunohistochemistry; aged ≥ 16 and ≤ 75 years; and patients must have received either an anthracycline- or ifosfamide-containing regimen. Eligible patients received afami-cel doses between 1-10 × 109 transduced T-cells after receiving lymphodepleting chemotherapy.

On November 18, 2022 Kintara Therapeutics, Inc.(Nasdaq: KTRA) ("Kintara" or the "Company"), a biopharmaceutical company focused on the development of new solid tumor cancer therapies, reported data from three posters that are being presented at the 2022 Society for Neuro-Oncology (SNO) Annual Meeting (Press release, Kintara Therapeutics, NOV 18, 2022, View Source [SID1234624247]).

ONCR-719 is a novel, armed oncolytic HSV-1 vector engineered with targeted entry via EGFR/EGFRvIII and expresses four immunomodulatory payloads designed to reverse GBM’s immunosuppressive tumor microenvironment. In addition, ONCR-719 is derived from a potent HSV-1 isolate to drive oncolysis, is engineered with fusogenic mutations to enhance viral spread, and uses Oncorus’ clinically validated microRNA attenuation strategy to inhibit viral replication in healthy cells.

Highlights from the preclinical poster describing ONCR-719, previously known as ONCR-GBM, include:

Minimal expression of HSV-1 virus entry receptor, NECTIN-1, on human GBM samples suggests targeted oncolytic viruses are required to effectively treat human GBM tumors.
ONCR-719 has been engineered to enter tumor cells using either EGFR/EGFRvIII or NECTIN-1 as an entry receptor, thereby increasing virus tropism for GBM tumors.
EGFR-targeting and engineered fusogenic mutations in ONCR-719 enhance virus spread and tumor immunogenicity by driving syncytia formation in human GBM tumor cell lines.
ONCR-719 is engineered to include IL-12, an anti-PD-1 nanobody, 15-hydroxyprostaglandin dehydrogenase (HPGD), and a novel macrophage modulating-Fc enhanced antibody. These payloads confer enhanced T cell recruitment and activation and target the immune suppressive macrophages and myeloid cells in the tumor microenvironment. Multiple payloads or transgenes were screened using in vivo orthotopic GBM models to identify immune-modulatory payloads to target the GBM microenvironment.
Together, EGFR/EGFRvIII targeting, oncolytic potency, and incorporation of rationally designed payloads within ONCR-719 leads to enhanced anti-tumor efficacy and complete responses in preclinical orthotopic GBM models.
ONCR-719 is engineered for safety in the central nervous system using multiple CNS-specific microRNA targets, Oncorus’ clinically proven strategy to limit viral replication in healthy cells. When injected intracranially in an HSV-1 sensitive mouse, ONCR-719 demonstrates a greater than 50,000-fold tolerability window compared to the unattenuated strain.
"Oncolytic viruses are well-positioned to treat this aggressive form of brain cancer. We are excited to share ONCR-719 as a cutting-edge preclinical candidate that is engineered to improve outcomes and can stimulate a productive and durable anti-tumor immune response across multiple mouse models following a single intratumoral injection," said Theodore (Ted) Ashburn, M.D., Ph.D., President and Chief Executive Officer of Oncorus. "Most notably, we’ve enabled the virus to use EGFR for entry, which is expressed at high levels in GBM. Underscoring the importance of this advance is our data showing that the canonical entry receptor for HSV, NECTIN-1, is only minimally expressed in GBM cells, which arguably makes using EGFR for entry an essential capability for such an agent. By utilizing our clinically proven microRNA attenuation strategy, ONCR-719 is engineered to protect healthy brain tissue while replicating at its full potential in tumor cells."

"GBM is the most common type of primary brain tumor in adults; it’s a devastating disease that has a great unmet need with a 5-year overall survival of approximately 7 percent," said Tooba Cheema, Ph.D., Senior Director, Translational Medicine and ONCR-719 Program Leader at Oncorus. "We engineered ONCR-719 to overcome the common impediment that this treatment class faces, limited spread of virus in the highly immunosuppressive GBM tumor microenvironment. We are pleased with the results demonstrated in preclinical models and look forward to seeing how our innovations translate into improved outcomes for GBM patients."

ONCR-719 is the company’s second candidate from its HSV Platform and is developed from a clinical isolate of HSV-1 selected for oncolytic potency across cancer cell lines. Further development of ONCR-719 is dependent on a strategic partnership or additional financing.

On November 18, 2022 Iovance Biotherapeutics, Inc. (NASDAQ: IOVA) reported that its ongoing rolling Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA) for lifileucel is expected to be completed in the first quarter of 2023 (Press release, Iovance Biotherapeutics, NOV 18, 2022, View Source [SID1234624239]).

As part of an amendment to the ongoing investigational new drug application (IND) submitted during the third quarter of 2022, Iovance received recent FDA feedback regarding supplemental assay validation information and comparability data for lifileucel. Iovance will address these FDA comments promptly and will now complete its rolling BLA submission during the first quarter of 2023.

Lifileucel is an investigational tumor infiltrating lymphocyte (TIL) therapy for patients with advanced (unresectable or metastatic) melanoma who progressed on or after prior anti-PD-1/L1 therapy, and targeted BRAF/MEK inhibitor therapy where appropriate. There are no FDA approved therapies in this treatment setting.

Frederick Vogt, Ph.D., J.D., Iovance’s Interim President and Chief Executive Officer stated, "We continue to make substantial progress with our ongoing BLA submission and remain close to the finish line. The FDA has provided recent valuable feedback to the IND application and remains supportive during the rolling BLA submission process. Iovance is fully committed to securing FDA approval as soon as possible to deliver the first individualized, one-time cell therapy for advanced melanoma patients, who have a significant unmet medical need."

As previously announced, Iovance held a successful pre-BLA meeting in July 2022, and the rolling BLA commenced in August 2022. A rolling BLA allows Iovance to submit portions of the BLA to the FDA on an ongoing basis, which enables the FDA to begin review as early as possible as documents are received. The rolling BLA submission and eligibility for priority review are benefits available under the FDA’s guidance on expedited programs for serious conditions. The FDA previously granted a regenerative medicine advanced therapy (RMAT) designation for lifileucel in advanced melanoma.

The BLA submission for lifileucel is supported by positive clinical data from the C-144-01 clinical trial in patients with advanced melanoma. The Phase 3 trial of lifileucel in combination with pembrolizumab in frontline advanced melanoma, on track to begin in late 2022, is intended to serve as a confirmatory study and is expected to be well underway at the time of a potential approval.
