Equecabtagene Autoleucel is the first CAR-T therapy in China that is self-developed with proprietary whole-process product development and the first BCMA-targeting CAR T-cell therapy in China with its NDA formally accepted by the NMPA. It is an innovative therapy co-developed by IASO Bio and Innovent. In February 2021, Equecabtagene Autoleucel was granted "Breakthrough Therapy Designation" by the NMPA.

The acceptance of NDA is based on data from a single-arm, open-label, multi-center phase 1/2 study（NCT05066646）being conducted in China. Study results showed that Equecabtagene Autoleucel has excellent safety and efficacy profiles, low immunogenicity given a fully-human scFv, robust expansion and prolonged persistence in vivo. It will potentially offer a breakthrough treatment option for patients with R/R MM. The data from the phase 1/2 clinical study of Equecabtagene Autoleucel was presented in an oral presentation at the 63rd American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Abstract #547) and the updated data was accepted as an oral presentation at the 27th Annual Congress of the European Hematology Association (EHA) (Free EHA Whitepaper)（EHA）Virtual Meeting (Abstract #S187) , held on June 9-12, 2022.

"Multiple Myeloma (MM) is the second-most-common hematologicmalignancy. Although the survival in MM patients has been dramatically extended to 7-10 years on average with recent drug development, the disease is still incurable and relapse or refractory after standard therapies is common for most MM patients. The later lines of treatment the patients are receiving, the shorter of survival time for those patients. Usually, the median progression-free survival of MM patients who had received at least third-line of prior therapy is only 3-6 months, and the overall survival time is less than 1 year. In recent years, there have been some encouraging breakthroughs in drugs and therapeutic interventions for the treatment of MM. The most exciting progress is BCMA CAR-T cell immunotherapy." said the two principal investigators at the primary study sites – Prof. Lugui Qiu, MD, from the Chinese Academy of Medical Science Hematology Hospital and Prof. Chunrui Li, MD, PhD, from Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology. "At the 63rd Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) in 2021, we reported the results of the clinical study on Equecabtagene Autoleucel injection. The study was conducted in 14 clinical centers and enrolled 79 patients with MM who had received at least third-line of prior therapy. Of the 79 patients, the overall response rate(ORR) was 94.9% and the complete response/stringent complete response (CR/sCR) rate was 58.2%. These study results showed that Equecabtagene Autoleucel has excellent safety and efficacy profiles. In addition, Equecabtagene Autoleucel also demonstrated favorable efficacy in patients with extramedullary multiple myeloma and patients who had received prior CAR-T therapy. These results suggest that Equecabtagene Autoleucel is potentially a new and effective immunotherapy treatment option for patients with multiple myeloma. We hope that Equecabtagene Autoleucel can be launched in China soon, bringing long-term benefits to patients."

Dr. Yongjun Liu, President of Innovent, said, "We are glad about the NDA acceptance of Equecabtagene Autoleucel, a product candidate co-developed by Innovent and IASO Bio, and it will potentially to be the domestic first approved and launch-to-market BMCA CAR-T therapy for multiple myeloma. In the clinical studies, Equecabtagene Autoleucel demonstrated impressive efficacy and favorable safety profiles. We hope that this breakthrough therapy could be approved in the near future and we will actively coordinate with all parties including the government authorities, hospitals, commercial insurance and charity funds to bring benefit to more multiple myeloma patients.

"IASO Bio currently has more than 10 innovative pipeline products under development. Equecabtagene Autoleucel is China’s first domestically developed CAR T-cell therapy with global intellectual property rights and the first BCMA-targeting CAR T-cell therapy with its NDA formally accepted by the NMPA. This is a significant milestone for IASO Bio. IASO Bio’s over 100,000 ft² manufacturing facility in Nanjing, which has end-to-end manufacturing capability that covers the entire CAR-T production process, received its drug manufacturing license earlier this year, will be the future commercial production site for Equecabtagene Autoleucel." said Wen (Maxwell) Wang, M.D., Ph.D., Chief Executive Officer and Chief Medical Officer of IASO Bio.

"In 2018, Professor Jianfeng Zhou of Tongji Hospital，Tongji Medical College led a team of clinicians and biologists to initiate clinical study of the world’s first fully-human BCMA CAR T-Cell therapy (Equecabtagene Autoleucel) for the treatment of multiple myeloma. The first patient of the study has maintained strict complete remission (sCR) for over 40 months." Maxwell added, "Many thanks to Professor Jianfeng Zhou for his unremitting efforts to promote the development of novel cell therapies and provide the impetus for the continuous innovation of CAR-T therapy. We look forward to the commercialization of Equecabtagene Autoleucel to bring hope to more multiple myeloma patients."

Innovent and IASO Bio are actively advancing the clinical development of Equecabtagene Autoleucel. In February 2022, it was granted "Orphan Drug Designation (ODD)"by the Office of Orphan Products Development (OOPD) of the U.S. Food and Drug Administration (FDA). In January 2022, IASO Bio and Innovent have jointly granted non-exclusive commercial rights of the fully-human BCMA CAR construct used in Equecabtagene Autoleucel to Sana Biotechnology (NASDAQ: SANA), a company focused on creating and delivering engineered cells as medicines, for use in its in vivo gene therapy and ex vivo hypoimmune cell therapy applications. Sana’s clinical and commercial development could further enhance the potential value of IBI326, benefitting a broader patient population. In addition to multiple myeloma, the NMPA has accepted IND application of Equecabtagene Autoleucel for the new expanded indication of Neuromyelitis Optica Spectrum Disorder (NMOSD).

About Multiple Myeloma (MM)

In the United States, MM accounts for nearly 2% of new cancer cases, and more than 2% of all cancer-related deaths. According to Frost & Sullivan, the number of new MM cases in the United States rose from 30,300 in 2016 to 32,300 in 2020 and is expected to increase to 37,800 by 2025. Additionally, the total number of patients diagnosed with MM increased from 132,200 in 2016 to 144,900 in 2020 and is expected to rise to 162,300 by 2025. In China, the number of new MM cases rose from 18,900 in 2016 to 21,100 in 2020 and is expected to increase to 24,500 by 2025. The total number of patients diagnosed with MM in China increased from 69,800 in 2016 to 113,800 in 2020 and is expected to rise to 182,200 by 2025.

On June 5, 2022 BioNTech SE (Nasdaq: BNTX, "BioNTech") reported initial data from an ongoing investigator-initiated first-in-human Phase 1 study evaluating the safety and tolerability of the mRNA-based individualized neoantigen specific immunotherapy (iNeST) autogene cevumeran (also known as BNT122, RO7198457) in combination with anti-PD-L1 immune checkpoint inhibitor atezolizumab and chemotherapy in patients with resected pancreatic ductal adenocarcinoma (PDAC) (Press release, BioNTech, JUN 5, 2022, View Source [SID1234615561]). Feasibility of the process of profiling each patient’s tumor to inform individualized vaccine design and on-demand manufacturing of iNeST in a clinically relevant timeframe was confirmed. The preliminary results showed a favorable safety profile as well as encouraging signs of clinical activity. The data have been presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) ("ASCO") Annual Meeting 2022 by Vinod Balachandran, M.D., at Memorial Sloan Kettering Cancer Center. Autogene cevumeran is the lead candidate from BioNTech’s iNeST platform, which is jointly developed together with Genentech, a member of the Roche Group, in multiple solid tumor indications.

The data presented at the ASCO (Free ASCO Whitepaper) Annual Meeting include a total of 19 patients who underwent surgery and received atezolizumab. 16 out of these 19 patients (84%) received autogene cevumeran at 9.4 weeks (median; 95% CI 9–10) after surgery. The preliminary data readout from these 16 vaccinated patients revealed that autogene cevumeran in combination with atezolizumab was well-tolerated. Only 1 of 16 patients (6%) developed a vaccine-related Grade 3 fever and hypertension, no other Grade 3 or higher adverse events were observed. In addition, the treatment induced de-novo, neoantigen-specific T cell response in half (8/16) of these patients from undetectable levels to large fractions of all blood T cells (median 2.9%). At an early median follow-up of 18 months, patients with de-novo immune response (n=8) had a significantly longer recurrence-free survival (RFS) as compared to those without vaccine-induced immune responses (n=8) (median not reached vs. 13.4 months, HR 0.08, 95% CI 0.01-0.4, P = 0.003). Based on these data, BioNTech and Genentech are planning a randomized study to further evaluate the efficacy and safety of autogene cevumeran in combination with atezolizumab and chemotherapy in patients with resected PDAC.

"With only under 5 percent of patients responding to current treatment options, PDAC is one of the highest unmet medical need cancers. We are committed to take up this challenge by leveraging our long-standing research in cancer vaccinology and are trying to break new ground in the treatment of such hard-to-treat tumors," said Prof. Özlem Türeci, M.D., Co-Founder and Chief Medical Officer at BioNTech. "The results of this Phase 1 study are encouraging. We look forward to further evaluating these early results in a larger randomized study."

The investigator-initiated, single-center, Phase 1 trial (NCT04161755) was designed to evaluate the treatment of the companies’ individualized immunotherapy candidate autogene cevumeran in combination with the anti-PDL-1 immune checkpoint inhibitor atezolizumab as an add-on to the standard-of-care regimen with adjuvant chemotherapy mFOLFIRINOX in patients with resected PDACs. The primary objective of the study is to assess the safety. Secondary objectives include the efficacy of the treatment measured as the 18-month RFS, the immunogenicity as well as the feasibility of the treatment regimen.

"Pancreatic cancer remains one of the deadliest cancers as it is resistant to all treatments, including immunotherapies. Conventional thinking has been that, as pancreatic cancers have few mutations, the immune system is unlikely to recognize mutation-derived neoantigens," said Vinod Balachandran, M.D., surgeon-scientist at Memorial Sloan Kettering Cancer Center and Principal Investigator of the study. "Our research, and now the results from this study show that the immune system can recognize neoantigens in pancreatic cancer, and that we can use mRNA vaccines to stimulate T cells to recognize neoantigens in pancreatic cancer patients. We now look forward to further investigating these results in a larger randomized trial."

BioNTech’s iNeST platform previously demonstrated encouraging results with a tolerable safety profile of autogene cevumeran as single agent and in combination with atezolizumab in a heterogenous patient population with advanced and heavily pretreated solid tumors. In a Phase1a/b trial autogene cevumeran revealed robust CD8+ and CD4+ T cell responses and a manageable safety profile (NCT03289962). In October 2021, BioNTech announced that the first patient was dosed in a randomized Phase 2 trial (NCT04813627) of autogene cevumeran in the adjuvant treatment of post-operative circulating tumor DNA (ctDNA) positive, surgically resected colorectal cancer. BioNTech and Genentech are also conducting a Phase II proof-of-concept study, which is designed to evaluate autogene cevumeran plus pembrolizumab in the first-line treatment of advanced melanoma (NCT03815058).

Title: Phase I Trial of adjuvant autogene cevumeran, an Individualized mRNA Neoantigen Vaccine, for Pancreatic Ductal Adenocarcinoma

Poster: 172
Abstract: 2516
About resected pancreatic ductal adenocarcinoma (PDAC)
PDAC is amongst the leading causes of cancer-related deaths in the United States with ~90% of patients dying within two years of their diagnosis. A combination of surgical removal and systemic cytotoxic chemotherapy has shown to improve clinical outcomes, however, even with surgical resection, the relapse rate remains high, and the 5-year overall survival is only approximately 20% in patients who undergo surgery followed by adjuvant chemotherapy (ACT) and only 10% in those who do not receive ACT. Thus, there is a high unmet medical need for novel therapies for patients with resected PDAC. The individualized Neoantigen Specific immunoTherapy (iNeST) candidate autogene cevumeran (also known as BNT122, RO7198457) provides a novel treatment strategy aimed to induce de-novo immune responses against cancer-specific neoantigens, recognize residual cancer cells and to prevent relapse.

About iNeST (individualized Neoantigen Specific immunoTherapy)
iNeST immunotherapies are individualized cancer therapies tailored to a specific patient’s tumor. They contain unmodified, pharmacologically optimized mRNA encoding up to 20 patient-specific neoantigens, identified using real-time next generation sequencing and bioinformatic neoantigen discovery. Neoantigens are proteins that are produced by cancer cells that differ from the proteins produced by healthy cells and are recognized by immune cells. The mRNA is encapsuled in BioNTech’s proprietary intravenous RNA-lipoplex delivery formulation which is designed to enhance stability as well as enable targeted delivery to dendritic cells. By analyzing each patient’s tumor, BioNTech is able to identify the cancer mutations that may act as neoantigens. Each individual cancer vaccine encodes for neoantigen candidates with the highest likelihood to help the immune system to recognize the cancer. For this purpose, BioNTech has developed a first of its kind, on-demand manufacturing process, following Good Manufacturing Practice (GMP) conditions.

An iNeST Fact Sheet and images from the iNeST manufacturing process are available in the media materials section on BioNTech’s website at this link.

Late-breaking Oral Presentation:

Orelabrutinib, an irreversible inhibitor of Bruton’s tyrosine kinase (BTK), for the treatment of SLE: results of a randomized, double-blind, placebo-controlled, phase Ib/IIa dose-finding study
Abstract Number: LB0005

The study is aimed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), preliminary efficacy and biomarkers of orelabrutinib in patients with mild to moderate SLE who received standard of care therapy.

The study randomized 60 patients with 55 patients who completed 12-week treatment. Baseline disease characteristics were generally balanced across treatment groups. Orelabrutinib was generally well tolerated in patients with SLE.

The plasma exposure of orelabrutinib (AUC and Cmax) was proportionally increased with doses. Nearly complete BTK occupancy was achieved at all dose levels, and the occupancy lasted for 24 hours.

In all evaluable patients, the SLE Response Index (SRI)-4 response rates at week 12 were 50.0%(7/14), 61.5%(8/13) and 64.3%(9/14) in patients treated with orelabrutinib at 50mg, 80mg and 100mg respectively, compared with 35.7%(5/14) in patients treated with placebo, which indicated a trend of dose-dependent improvement.

Among the small cohort of subgroup of patients with SLEDAI-2K≥8 at screening, SRI-4 response occurred in 70%(7/10), 70%(7/10) and 66.7%(6/9) of patients who received orelabrutinib at 50mg, 80mg and 100mg, respectively, compared with 30%(3/10) who received placebo.

A biological signal of reduced proteinuria, anti-dsDNA and IgG, total B cells and increased complements C4 were also observed following orelabrutinib administration.

Professor Zhanguo Li said, "Orelabrutinib was generally well tolerated in patients with SLE. We are encouraged by the preliminary results suggesting trends in efficacy and supporting further studies in longer-term trials and larger cohorts of SLE patients."

About Orelabrutinib

Orelabrutinib is a highly selective BTK inhibitor developed by InnoCare for the treatment of cancers and autoimmune diseases.

On Dec. 25 2020, orelabrutinib received conditional approval from the China National Medical Products Administration (NMPA) in two indications: the treatment of patients with relapsed/refractory chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL), and the treatment of patients with relapsed/refractory mantle cell lymphoma (MCL). At the end of 2021, orelabrutinib was included into National Reimbursement Drug list to benefit more lymphoma patients.

In addition to the approved indications, multi-center, multi-indication clinical trials are underway in the US and China with orelabrutinib as monotherapy or in combination therapies.

Orelabrutinib was granted as Breakthrough Therapy Designation for the treatment of r/r MCL by U.S. Food and Drug Administration (FDA).

In addition, orelabrutinib is also being evaluated in global phase II studies for the treatment of Multiple Sclerosis (MS), and clinical trials for the treatment of SLE, Primary Immune Thrombocytopenia (ITP) and Neuromyelitis Optica Spectrum Disorder (NMOSD) in China.

On June 5, 2022 Lytix Biopharma AS ("Lytix" or the "Company"), a clinical-stage company with an in situ vaccination technology platform, reported data from its ATLAS-IT-04 trial in patients with progressive metastatic soft tissue sarcoma (STS) (Press release, Lytix Biopharma, JUN 5, 2022, View Source [SID1234615594]). The data from this Phase II proof of concept study shows that LTX-315 in combination with Adoptive Cell Therapy (ACT) was able to stabilize the disease in 3 out of 4 fully treated patients in this hard-to-treat patient population, and that the LTX-315 treatment generated tumor-specific T cells.

The data is presented June 5th, 2022, as a poster at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2022 Annual Meeting, Chicago, IL, U.S.A.

The ATLAS-IT-04 trial was an open label, exploratory, Phase II trial assessing the effect of LTX-315 when used in combination with ACT in patients with metastatic STS. ACT with tumor infiltrating lymphocytes (TILs) is a potent treatment that can induce complete and durable tumor regression as documented in patients with melanoma. The use of ACT with TILs for patients with advanced STS has not previously been reported.

Patients with advanced stages of STS have few effective treatment options and respond poorly to current treatment as well as to immunotherapy tested in clinical trials. The trial design of ATLAS-IT-04 included intratumoral injections of LTX-315 ahead of surgical removal of tumors, followed by in vitro expansion of T cells as the first step. In a second step, the expanded T cells were infused back to the patients and the effect of LTX-315 on the tumor microenvironment was assessed.

LTX-315 is a first-in-class non-viral oncolytic molecule, representing a new and superior in situ therapeutic vaccination principle to boost the clonal expansion of T cells that kill tumor cells through a targeted immune response. In a recent Phase I/II study LTX-315 has been shown to increase TILs in malignant solid tumors after intratumoral injection.

The immune response data from the ATLAS-IT-04 trial demonstrates that the treatment induce both new and tumor-specific T cells which provides proof to the concept that LTX-315 generates an immune response that targets the tumor. Moreover, the data shows that LTX-315 induce expansion of a heterogenous pool of T-cell clones in blood, and a pool of these are also present in tumor tissue after treatment.

"This trial demonstrates that the combination of LTX-315 and ACT is not only feasible and tolerable, but that tumor-specific T cells can be expanded in vitro from tumors that have been pretreated with the oncolytic molecule LTX-315", Inge Marie Svane, PI and Professor at the National Center for Cancer Immune Therapy, Department of Oncology, Copenhagen University Hospital, comments.

She adds: "This combination therapy invokes tumor specific T cells that can be cultured and infused as part of an adoptive transfer regimen for several subtypes of soft tissue sarcoma, and its treatment schedule should be further optimized to achieve superior signs of efficacy."

The poster is presented June 5th at the ASCO (Free ASCO Whitepaper) 2022 Annual Meeting.

On June 5, 2022 Agendia, Inc., a commercial-stage company focused on improving outcomes for breast cancer patients worldwide by providing physicians and patients with next-generation diagnostic and information solutions to inform optimized treatment decision-making, reported it will present seven posters derived from the company’s FLEX Trial, the real-world, multicenter, prospective, observational breast cancer study at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (ASCO) (Free ASCO Whitepaper) 2022 (Press release, Agendia, JUN 5, 2022, View Source [SID1234615578]).

One of Agendia’s posters, selected for the oral discussion session, titled Whole transcriptomic analysis of HR+ breast cancer in Black women classified as basal-type by BluePrint [Reid, S., et al.], will present findings from a racially-diverse cohort and resulting transcriptomic analyses suggesting hormone receptor-positive (HR+)/Basal tumors are biologically similar to triple-negative breast cancer (TNBC) tumors, regardless of race, demonstrating the importance of subtyping a tumor’s biology to determine optimal treatment course. BluePrint also identified racial disparities in the proportion of HR+/Basal tumors, showing a near doubling of such tumors among Black women, underscoring the need for diverse representation in clinical trials, a hallmark of the FLEX Trial.

"Leveraging the BluePrint assay, we are able to uncover new gene expression insights for HR+/Basal breast cancer tumors, which traditionally are more aggressive, higher grade, and disproportionally impact Black women compared to White women," said Sonya Reid, MD, MPH, Department of Medicine, Vanderbilt University Medical Center. "The FLEX Trial’s robust collection of diverse patient genomic profiles uniquely allows for sub-studies analyses like these to take place, helping researchers better support their patients from all racial and ethnic backgrounds with further classification of breast cancer tumors."

These data build on findings presented at San Antonio Breast Cancer Symposium 2021, also authored by Dr. Reid, that showed MammaPrint and BluePrint more robustly identify differences in more aggressive breast cancers in Black and White women beyond clinical factors, highlighting the fundamental importance of genomic classification and personalized treatment planning.

In addition, Agendia will present several sub-studies highlighting the FLEX Trial’s approach to cancer research by accelerating impactful data generation, aimed at redefining cancer care. The company believes this patient-centric design and national network of participating sites backed by Agendia will allow its investigator-initiated sub-studies to produce important results with the potential to drive science forward, like those being shared at ASCO (Free ASCO Whitepaper) 2022:

Clinical implications for patients with discordant Oncotype and MammaPrint results [Socoteanu, M., et al.] recalls findings from the IMPACT trial, which demonstrated MammaPrint and BluePrint inform treatment planning and increase physician confidence. In an effort to examine consistency among genomic tests, researchers analyzed therapy implications for patients who received both results from MammaPrint and BluePrint as well as OncotypeDx within the FLEX Trial:
Of 722 patients, 49% were observed to have discordant results with the potential of negative clinical impact. This includes 27% who may be undertreated, 6% potentially overtreated, and 10% who may not be given the option to decrease endocrine therapy to two years based on MammaPrint Ultra Low genomic risk assessment. Of 114 concordant MammaPrint High Risk tumors, 14% were genomically classified as Basal, and likely require more aggressive chemo than typically used in estrogen receptor-positive (ER+) breast cancers.
Together, these analyses showed more than half the patients in this cohort were at potential risk for undertreatment or overtreatment, had they received an OncotypeDx test as a standalone test. Discordance between OncotypeDx Recurrence Scores and MammaPrint with BluePrint results, most often yields the potential for undertreatment if the Recurrence Score is relied upon for treatment decision-making, putting a significant amount of risk on the patient since undertreatment may result in an incurable metastatic recurrence.
Whole transcriptome analysis of tumors with discordant Oncotype and MammaPrint results in the FLEX trial [Socoteanu, M., et al.] also looked at the differences in quality of results from OncotypeDx Recurrence Scores in comparison to MammaPrint results, this time by evaluating the genomic diversity within each test’s classification. The analysis found a high amount of genomic diversity within the OncotypeDx Recurrence Score Intermediate group, while conversely showing MammaPrint further classifies cases into more genomically rich and distinct categories, allowing for more precise treatment pathways based on the individual tumor.
Investigation of a genomic signature for transcription factor MAF gene amplification and lack of bisphosphonate benefit in early breast cancer [Nasrazadani, A. et al.] provides whole transcriptome analyses suggesting breast cancer tumors with mesenchymal aponeurotic fibrosarcoma (MAF) gene amplifications – a biomarker associated with shortened survival and lack of bisphosphate benefit when related to bone metastases in breast cancer – may be identified by a unique gene expression pattern. In this study, researchers used the MammaPrint/BluePrint platform to identify a set of 57 genes that could potentially predict MAF amplification status which could enable a woman’s care team to potentially anticipate a lack of benefit from adjuvant bisphosphonate treatment. Additionally, these results show mining the complete genome more thoroughly provides expanded insights and can shed light on new biomarkers previously unknown.
Distribution of breast cancer molecular subtypes within receptor classifications: Lessons from the I-SPY2 trial and FLEX Registry [Cha, J., et al.] proposes that the breast cancer research community drive science forward and work with the NCI’s Surveillance, Epidemiology, and End Results (SEER) Program to update its immunohistochemical (IHC) labels to avoid overlap with molecular subtype nomenclature and incorporate more modern classifications when available. Study results show the SEER Program database using IHC labels is not accurately identifying genomic subtypes via its annotations. In fact, the categorizations in the population-based registry were discordant with MammaPrint and BluePrint results in 52% of I-SPY2 Trial cases and 43% of FLEX Trial cases, emphasizing the growing importance of molecular subtyping to inform treatment and epidemiological research.
Defining transcriptomic profiles of early-stage mucinous breast cancers: A FLEX sub study [Sivapiragasam, A., et al.] revealed although mucinous breast cancer (MuBC), a rare subtype of invasive ductal carcinoma (IDC) accounts for less than 2% of all breast cancers, it often is expected to have low clinical risk and a favorable prognosis, however new genomic testing showed half of the patients observed in the study were in fact classified as MammaPrint High Risk. Through the examination of transcriptomic profiles, the findings demonstrated MammaPrint Low Risk MuBC is biologically different from MammaPrint Low Risk IDC providing new evidence as to why there are more favorable prognoses. Results also indicated MammaPrint High Risk MuBC and High Risk IDCs are highly genomically similar and could benefit from chemotherapy, providing additional clarity to guide specific treatment among these breast cancer subtypes.
FLEX, the 30,000 breast cancer transcriptome project: A platform for early breast cancer research using full-genome arrays paired with clinical data [Ma, C., et al.] shares data from the 38 investigator-initiated sub-studies – including five investigating racial disparities – approved within the FLEX Real World Evidence Trial (NCT03053193). Since the trial’s inception in 2017, FLEX has enrolled 10,000 patients at over 109 sites with a diverse data set designed to meet the needs of historically under-represented patients with breast cancer.
"These new findings presented at ASCO (Free ASCO Whitepaper) 2022 show the breadth of the FLEX research platform to identify and evaluate the many different complexities of a breast cancer biology at diagnosis that may facilitate more precise and individualized treatment recommendations," said William Audeh, MD, Chief Medical Officer at Agendia. "Agendia’s commitment to expanding our understanding of breast cancer to improve outcomes for women with breast cancer is astounding, exemplified by the FLEX Real World Evidence Trial. FLEX has the significant potential to broaden the application of genomic information through assays such as MammaPrint, BluePrint, and new proprietary Agendia signatures, which could lead to practice-changing models within breast cancer care aimed at improved outcomes for women with breast cancer."
