PreludeDx™ Presents New Data at SABCS Spotlight Session Re-Classifying Patients Meeting RTOG 9804 Low Risk Criteria as Elevated Risk Using DCISionRT®

On December 15, 2020 Prelude Corporation (PreludeDxä), a leader in molecular diagnostics and precision medicine for early stage breast cancer, presented clinical outcomes data last week at the San Antonio Breast Cancer Symposium (SABCS) that further validates the DCISionRT test results of an independent study by Kaiser Permanente Northwest published earlier this year in Clinical Cancer Research (Press release, Prelude Therapeutics, DEC 15, 2020, View Source [SID1234572899]). DCISionRT is a biologic risk signature that assess the 10-yr risk of a subsequent breast cancer recurrence. A Spotlight Poster presented at SABCS, showed that the DCISionRT test reclassified 45% of patients meeting RTOG 9804 low risk or ‘good risk’ criteria for Ductal Carcinoma In Situ (DCIS) as Decision Score (DS) Elevated Risk. These patients who were reclassified by the DCISionRT test to DS Elevated Risk had clinically elevated 10-year breast cancer rates when treated without radiation therapy (RT) and demonstrated an 84% relative benefit with RT.

The company’s Spotlight Poster, entitled DCIS biosignature reclassified patients, who met RTOG 9804 or ECOG-ACRIN E5194 low-risk clinicopathologic criteria into an elevated invasive risk group who benefited significantly from radiation therapy, was presented on Thursday, December 10 by Dr. Chirag Shah, Director of Breast Radiation Oncology and Director of Clinical Research – Radiation Oncology at Cleveland Clinic.

RTOG 9804 criteria is based on traditional clinical and pathological features and is used to identify low risk or ‘good risk’ DCIS patients. In this study, complete biomarker data was available for 535 women meeting ‘good risk’ clinicopathologic RTOG 9804-like criteria. In the DCISionRT DS Low Risk group there was no significant reduction from RT. However, in the DCISionRT DS Elevated Risk group, RT significantly reduced invasive breast cancer risk by 84%.

"In this study we examined the utility of the DCISionRT test to identify patients who otherwise met traditional ‘good-risk’ criteria but remained at an elevated invasive risk after lumpectomy," said
Dr. Shah. "The study supports the use of DCISionRT, which provides a ten-year breast event risk with and without radiation therapy after lumpectomy, as compared to traditional clinical and pathological features when making radiation therapy decisions following breast conserving surgery in patients with DCIS."

Similar results were previously reported by an independent validation of DCISionRT conducted by Kaiser Permanente Northwest (KPNW), which included a 455 patient cohort. DCISionRT reclassified approximately 50% of patients meeting ‘good risk’ criteria like RTOG 9804 as DS Elevated Risk. Women in the DS Elevated Risk category in the KPNW cohort had a 21% 10-yr invasive recurrence rate when treated with lumpectomy and without RT, and a 6% rate when receiving radiation therapy.

"We appreciate the opportunity to have worked alongside such esteemed physicians and organizations and are thrilled to announce another strong data set supporting the integration of DCISionRT into clinical practice management for DCIS," said Daniel Forche, President and CEO of PreludeDx. "Women and their physicians contemplating the next treatment steps now can make a personalized decision for radiation therapy that includes their individual tumor biology to add or omit radiation therapy after breast conserving surgery."

About DCISionRT for Breast DCIS

DCISionRT is the only risk assessment test for patients with ductal carcinoma in situ (DCIS) that predicts radiation therapy benefit. In the US, over 60,000 women are newly diagnosed with DCIS each year. DCISionRT, developed by PreludeDx and built on research that began with funding from the National Cancer Institute, enables physicians to better understand the biology of DCIS. DCISionRT combines the latest innovations in molecular biology with artificial intelligence and machine learning to assess a woman’s individual tumor biology along with other risk factors and provide a personalized recurrence risk. The test provides a Decision ScoreTM that identifies a woman’s risk as low or elevated. DCISionRT’s intelligent reporting provides a woman’s recurrence risk after breast conserving surgery alone and with the addition of radiation therapy. In turn, this new information may help patients and their physicians to make more informed treatment decisions.

NKTR-255 is designed to activate the IL-15 pathway and expand Natural Killer (NK) cells as well as promote the survival and expansion of CD8+ T cells without inducing suppressive regulatory T cells. Cetuximab is a monoclonal antibody against epidermal growth factor receptor (EGFR) and is approved for the treatment of advanced HNSCC and CRC.

"An NK-cell agent such as NKTR-255 is a perfect and unique complement to monoclonal antibody therapies which induce antibody-dependent cellular cytotoxicity," said Wei Lin, MD, Head of Development at Nektar. "Our body of preclinical and clinical data for NKTR-255 demonstrates that this novel agent not only induces NK cell proliferation but also enhances their cytotoxic immune effector function. With this new Phase 1/2 study in HNSCC and CRC, we are excited to expand our NKTR-255 development program beyond the hematological setting into solid tumors."

Nektar recently presented the first clinical data for NKTR-255 at the most recent 2020 Society for Immunotherapy in Cancer (SITC) (Free SITC Whitepaper) Annual Meeting in November. The data demonstrated that NKTR-255 was well tolerated and biologically active, and treatment resulted in consistent expansion of lymphocytes, with durable and sustained increases in NK and CD8+ T cells in a highly refractory population of patients with multiple myeloma (MM) and non-Hodgkin lymphoma (NHL).

The new Phase 1b/2 study will test the combination of NKTR-255 with cetuximab in two groups of patients. One group will consist of R/R head and neck cancer patients who have progressed after treatment with platinum-based chemotherapy and a checkpoint inhibitor. The second group will include patients with metastatic colorectal cancer who have received two prior treatments for metastatic disease. The trial will begin with a dose-finding portion for the combination, which will then be expanded into dedicated cohorts for head and neck and colorectal cancer patients.

About NKTR-255

NKTR-255 is an investigational IL-15 receptor agonist designed to activate the IL-15 pathway and expand NK cells and promote the survival and expansion of memory CD8+ T cells without inducing suppressive regulatory T cells. Through optimal engagement of the IL-15Rα/IL-2Rβγ receptor complex, NKTR-255 enhances functional NK cell population and formation of long-term immunological memory, which may lead to sustained anti-tumor immune response. NKTR-255 is uniquely designed to overcome the challenges of recombinant IL-15 and other IL-15 agonists, which are rapidly cleared from the body and have shown diminishing response to successive doses.1 NKTR-255 is wholly-owned by Nektar.

The gold nanoparticle component of ALAN is believed to enhance radiation therapy by "magnifying" the effects of radiation on the targeted tumor cells with the potential to justify lower radiation exposure and, in turn, decrease side effects. ALAN may also potentially be used in combination with MRIs to provide higher-resolution images of solid tumors and tumor cells as special imaging dyes attach to the gold nanoparticle compound.

"With the issuance of this patent, we continue to build our intellectual property portfolio as a key component to protect our technologies under development," stated Michael Poirier, Qualigen’s Chairman, Chief Executive Officer and President. "ALAN is a valuable therapeutic platform technology that may be applied in numerous indications. Currently, we are evaluating strategic options on how to develop and monetize these additional applications while we continue to advance ALAN in our development pipeline against acute myeloid leukemia."

ALAN is a DNA aptamer-based anticancer drug candidate that combines the DNA aptamer AS1411 with a gold nanoparticle to dramatically increase its potency. This drug candidate has the potential to target and destroy tumor cells in a wide variety of cancer types with minimal side effects. The Company plans to commence Phase 1 human trials with ALAN in 2021 in patients with acute myeloid leukemia, its lead indication.

"The issuance of this patent for ALAN further protects this technology’s potential broad applicability as a treatment for cancer," added Paula Bates, PhD, Professor of Medicine at UofL. "We look forward to our continued collaboration with Qualigen as we plan to enter this drug candidate into clinical trials as a therapeutic next year. We believe ALAN has the potential to be more targeted than available cancer treatments with the ability not to harm normal healthy cells resulting in less side effects for the patient."

Qualigen currently has 58 issued and pending patents and has in-licensed rights to a further 42 issued and pending patents.
