CHOP Researchers Define a 3-Tiered Molecular Classification of Pediatric Differentiated Thyroid Cancer, where Fusion Oncogenes Predict the Most Invasive Behavior

On January 31, 2022 Children’s Hospital of Philadelphia (CHOP) reported that Fusion oncogenes, such as RET- and NTRK-gene fusions, are associated with more invasive pediatric thyroid cancers, correlating with the highest risk of metastases and a lower likelihood of achieving remission one year after initial therapy (Press release, CHOP, JAN 31, 2022, View Source [SID1234607530]). The findings, which were published in the Journal of Clinical Oncology, contrast those previously established in adults, for whom BRAF mutations, not fusion oncogenes, are associated with more invasive disease that is less response to therapy.

"This study shows fusion oncogenes are more prevalent in pediatric thyroid cancer that is likely to spread to the lungs, whereas tumors with RAS-like and BRAF mutations are associated with low- and intermediate risk, respectively," said Andrew J. Bauer, MD, Director of the Pediatric Thyroid Center at Children’s Hospital of Philadelphia and senior author of the study. "This provides an opportunity for increased collaboration among surgeons, endocrinologists, and oncologists to stratify the treatment of tumors, approaching RAS-like mutations with less extensive surgery, while also exploring the new treatment protocols using FDA-approved oncogene specific inhibitors to optimize the treatment of patients with lung metastasis."

The results from the CHOP thyroid team are a pediatric-specific follow-on study to the 2014 Cancer Genome Atlas (TCGA) report that classified adult papillary thyroid cancer (PTC) into two molecular subtypes – RAS-like or BRAF-like – and concluded that molecular classification more accurately reflected tumor behavior, including disease severity and prognosis. To determine whether the adult based TCGA classification predicted the similar clinical behavior and outcomes in pediatric patients with DTC, the CHOP researchers analyzed 131 pediatric thyroid tumors. Of those, 66 were collected and sequenced using the CHOP Division of Genomic Diagnostics platform between 2016 and 2019, with the remaining 65 collected between 1989 and 2012 and sequenced on a commercial platform. In analyzing the sequenced samples, the researchers categorized mutated genes into three categories: RAS-mutant, BRAF-mutant, and RET/NTRK fusions. The researchers evaluated these categories against numerous parameters, including patient demographics, thyroid pathology, and clinical characteristics.

The researchers found that the three-tier classification system more accurately reflected the clinical behavior of DTC in pediatrics. Based on the low prevalence of RAS-mutant tumors among the pediatric samples and their low-risk of metastasis, the CHOP researchers limited their statistical analysis to comparing samples with a BRAF mutation to samples with RET/NTRK fusions. The researchers found no distant metastasis in any patients with BRAF-mutant thyroid tumors, whereas 36% of patients with RET/NTRK fusions had distant metastasis. Persistent disease at one year was also more frequent in the subgroup harboring RET/NTRK fusions: 36% vs. 17% among those with a BRAF mutation.

In line with prior studies, the researchers also found that RET/NTRK fusions are more common in PTC patients under the age of 10. Of the samples in their analysis, 91% of those in patients under the age of 10 harbored fusion events. The prevalence gradually decreased in pediatric patients older than 10 years (27%) and into adulthood (9%). By contrast, only one BRAF mutation (9%) was found among patients under the age of 10, compared with 25 pediatric patients aged 10 years or older (20%) and 58% of adults with PTC.

"Considering the high prevalence of RET/NTRK fusions in pediatric differentiated thyroid cancer, and their association with more metastatic behavior, it will be crucial to generate the transcriptional signatures of RET/NTRK and BRAF-mutant subgroups in the pediatric population to understand the differential impact of these alterations on signaling pathways, differentiation, and clinical outcomes," said first author Aime T. Franco, PhD, investigator in the Center for Childhood Cancer Research and director of the Pediatric Thyroid Cancer Translational Research Laboratory at Children’s Hospital of Philadelphia. "Future research in our Thyroid Center Frontier Program at CHOP will also investigate the underlying reason for the significant differences between children and adults when it comes to invasive disease, as well as the role of BRAF and RET/NTRK in response to radioiodine therapy."

Immune-Onc Therapeutics Announces FDA Clearance of IND Application to Initiate Trial of IO-202, a First-in-Class Myeloid Checkpoint Inhibitor Targeting LILRB4, in Patients with Advanced Solid Tumors

On January 31, 2022 Immune-Onc Therapeutics, Inc. ("Immune-Onc"), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting immunosuppressive myeloid checkpoints, reported that the U.S. Food and Drug Administration (FDA) has cleared the company’s Investigational New Drug (IND) application for IO-202, a first-in-class antibody targeting leukocyte immunoglobulin-like receptor B4 (LILRB4, also known as ILT3), for the treatment of solid tumors (Press release, Immune-Onc Therapeutics, JAN 31, 2022, View Source [SID1234607529]).

Myeloid cells are abundant and often immune suppressive in the solid tumor microenvironment. The LILRB4 receptor is expressed on monocytic myeloid cells, including dendritic cells, and contributes to a tolerogenic myeloid cell phenotype, resulting in decreased tumor immune surveillance. In preclinical data presented at the 2021 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, IO-202 was found to enhance dendritic cell function and T cell activation in vitro and promote anti-tumor immunity in a solid tumor model in vivo. These data provided a strong rationale to evaluate the therapeutic potential of IO-202 as a myeloid checkpoint inhibitor in solid tumors.

"The FDA clearance to begin our Phase 1 study for IO-202 in solid tumors is a major milestone for Immune-Onc, which represents the third IND for our pipeline and the second for IO-202," said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. "We know that high LILRB4 expression on myeloid cells infiltrating solid tumors contributes to tumor immune evasion. IO-202 is a first-in-class myeloid checkpoint inhibitor targeting LILRB4, which may provide therapeutic benefit to multiple solid tumor types where evasion of the immune system allows disease to progress and create resistance to therapy, including to T cell checkpoint inhibitors. We look forward to advancing IO-202 into the clinic to evaluate its potential as a monotherapy and in combination with an anti-PD-1 in patients with solid tumors."

The Phase 1, multicenter, dose-escalation and dose expansion study will consist of a monotherapy cohort and a combination therapy cohort to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of IO-202 alone and in combination with pembrolizumab, an anti-PD-1 antibody, followed by indication-specific expansion cohorts to be treated with IO-202 in combination with pembrolizumab at the recommended Phase 2 dose. Various biomarkers will be assessed to enable a mechanistic understanding of clinical data and inform future trials. This study may also provide an opportunity to identify preliminary efficacy signals.

ABOUT LILRB4 (also known as ILT3)

LILRB4, also known as ILT3, is an immune inhibitory transmembrane protein found on monocytic myeloid cells, including dendritic cells. LILRB4 inhibits antigen-presenting cell activation, resulting in immune tolerance. LILRB4 is also expressed on certain hematologic cancer cells and monocytic myeloid cells in the solid tumor microenvironment. Immune-Onc and The University of Texas published pioneering research in Nature illuminating the role of LILRB4 in immune suppression and tumor infiltration in acute myeloid leukemia (AML) and presented the rationale for targeting LILRB4 in solid tumors at the AACR (Free AACR Whitepaper) Annual Meeting 2021.

ABOUT IO-202

IO-202 is a first-in-class LILRB4 antagonist antibody with broad potential as an immunotherapy in both blood cancers and solid tumors. In hematologic malignancies, preclinical studies showed that IO-202 converts a "don’t kill me" to a "kill me" signal by activating T cell killing and converts a "don’t find me" to a "find me" signal by inhibiting infiltration of blood cancer cells. In solid tumors, preclinical data showed that IO-202 enhances dendritic cell function and T cell activation in vitro and inhibits tumor growth in a solid tumor model in vivo.

IO-202 is currently in Phase 1 clinical development for the treatment of AML and chronic myelomonocytic leukemia (CMML). The U.S. Food and Drug Administration granted IO-202 Orphan Drug Designations for treatment of AML in 2020. The company has received IND clearance to evaluate IO-202 in solid tumors in January 2022.

Janssen Submits Marketing Authorisation Application to the European Medicines Agency Seeking Approval of Bispecific Antibody Teclistamab for the Treatment of Patients with Relapsed or Refractory Multiple Myeloma

On January 31, 2022 The Janssen Pharmaceutical Companies of Johnson & Johnson reported the submission of a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) seeking approval of teclistamab for the treatment of patients with relapsed or refractory multiple myeloma (RRMM) (Press release, Johnson & Johnson, JAN 31, 2022, View Source [SID1234607527]). Teclistamab is an investigational, off-the-shelf, T-cell redirecting, bispecific antibody targeting both B-cell maturation antigen (BCMA) and CD3.1

"Despite the significant progress that has been made in the treatment of multiple myeloma, it remains an incurable cancer, with approximately half of newly diagnosed patients not reaching five-year survival and almost a third dying within one year of diagnosis," said Edmond Chan MBChB M.D. (Res), Senior Director, EMEA Therapeutic Area Lead Haematology, Janssen-Cilag Limited. "Today’s submission is an important step forward in our mission to improve outcomes for people living with multiple myeloma, where the need for new treatment strategies remains high."

In December 2021, the EMA granted accelerated assessment for teclistamab. Accelerated assessment reduces the timeframe for the Committee for Medicinal Products for Human Use (CHMP) to review a MAA and is granted when a medicinal product is of major interest for public health and therapeutic innovation.2

The submission to the EMA is supported by data from MajesTEC-1 (NCT03145181, NCT04557098), an open-label, multicentre clinical trial evaluating the safety and efficacy of teclistamab in adults with RRMM.1 Efficacy outcomes assessed included overall response rate, very good partial response and complete response, using the International Myeloma Working Group (IMWG) criteria.3 Safety outcomes evaluated included dose limiting toxicity and the number of participants with adverse events as a measure of safety and tolerability.4 Updated MajesTEC-1 data were recently presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2021 annual meeting.1

"We are pleased to announce the submission of teclistamab to the European Medicines Agency. Once again, this shows our commitment to continue to provide innovative, transformative therapies for patients with relapsed or refractory multiple myeloma," said Peter Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC.

The application to the EMA follows a Biologics License Application (BLA) submitted to the U.S. Food and Drug Administration (FDA) seeking approval of teclistamab for the treatment of RRMM. Additionally, a MAA for teclistamab was recently submitted to the Swiss Agency for Therapeutic Products (Swissmedic) through a Type A Project Orbis submission. Project Orbis is an initiative of the FDA Oncology Center of Excellence, and provides a framework for concurrent submission and review of oncology products among international partners, with the aim of facilitating faster patient access to high-impact, innovative cancer therapies across multiple countries.5 A Type A application is submitted concurrently (within 30 days) to the FDA and the Project Orbis Partners (POPs), allowing for maximal collaboration during the review phase and the possibility of concurrent approval decisions.5

About Teclistamab
Teclistamab is an investigational, off-the-shelf, T-cell redirecting bispecific antibody targeting both BCMA and CD3. BCMA is expressed at high levels on multiple myeloma cells.6,7,8,9,10 Teclistamab redirects CD3-positive T-cells to BCMA-expressing myeloma cells to induce killing of tumour cells.11

Teclistamab is currently being evaluated in several monotherapy and combination studies.3,12,13,14,15 In 2020, the European Commission (EC) and the U.S. FDA each granted teclistamab Orphan Drug Designation for the treatment of multiple myeloma. In January 2021 and June 2021, teclistamab received a PRIority MEdicines (PRIME) designation by the EMA and Breakthrough Therapy Designation (BTD) by the FDA, respectively. PRIME offers enhanced interaction and early dialogue to optimise drug development plans and speed up evaluation of cutting-edge, scientific advances that target a high unmet medical need.16 The FDA grants BTD to expedite the development and regulatory review of an investigational medicine that is intended to treat a serious or life-threatening condition and is based on preliminary clinical evidence that demonstrates the drug may have substantial improvement on at least one clinically significant endpoint over available therapy.17

About Multiple Myeloma
Multiple myeloma is currently an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.18,19 When damaged, these plasma cells change and grow out of control. Abnormal plasma cells can crowd out or suppress the growth of other healthy cells in the bone marrow.19 In Europe, more than 50,900 people were diagnosed with multiple myeloma in 2020, and more than 32,500 patients died.20 While some patients with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms, which can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels, or kidney failure.21
