Breast cancer is one of the most common cancers associated with LMD, a devastating complication in which cancer spreads to the membrane surrounding the brain and spinal cord. The current standard of care for diagnosing LMD is through clinical evaluation, imaging and cytology, which have limited sensitivity. Median survival after a diagnosis of LMD is just two to three months.

The case series included four breast cancer patients, ages 32 to 57, with suspected LMD who were treated at four different institutions. CNSide and cytology were used in parallel to detect tumor cells in the cerebrospinal fluid at diagnosis and throughout treatment. CNSide was also used to determine tumor cell counts and the presence of HER2 amplification to help guide therapy. At diagnosis, CNSide detected cancer cells in three of three patients, compared with two of three patients for cytology. (The fourth patient was diagnosed before CNSide was available.) CNSide detected CSF tumor cells in all eleven measurements taken, compared to six of eleven using cytology. Throughout treatment, CNSide showed a decrease in CSF tumor cells in all four patients, ranging from 99.7% to 100%, corresponding with an improved clinical response.

"Having a quantitative assay that provides tumor cell counts, rather than just a positive or negative result, is a major advance in the management of patients with leptomeningeal disease," said Priya Kumthekar, M.D., Neuro-Oncologist and Associate Professor of Neurology at Northwestern Medicine’s Feinberg School of Medicine, who will present the case series poster. "A positive cytology result may suggest that the patient is not responding to treatment, which could lead to therapy being stopped or changed. As this case series shows, CNSide’s quantitative results may show that, in fact, the tumor cell count has dropped dramatically, indicating that the patient is responding, and therapy should be continued."

"These cases illustrate the value of CNSide in treatment response monitoring and identification of targets for therapy that can produce a sustained response in leptomeningeal disease," said Michael Dugan, M.D., Chief Medical Officer and Medical Director of Biocept. "CNSide has the potential to allow clinicians to have more confidence in their treatment decisions, improving the clinical management of leptomeningeal disease in a way that may help patients see improvement in symptoms and live significantly longer lives."

The case series was completed by neuro-oncologists from Smilow Cancer Hospital at Yale New Haven Health, Lou and Jean Malnati Brain Tumor Institute at Northwestern Medicine, UT Southwestern Medical Center and Barrow Neurological Institute.

"Onco360 is honored to become a specialty pharmacy provider for BESREMi patients," said Benito Fernandez, Chief Commercial Officer, Onco360. "We are committed to supporting the highly specialized needs of polycythemia vera patients and their physicians across the United States."

According to the National Comprehensive Cancer Network (NCCN) Guidelines for the Treatment of Myeloproliferative Neoplasms, polycythemia vera is one of several disorders of the hematopoietic system under a broader classification known as Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs). The prevalence of polycythemia in the United States is approximately 148,000 cases.1 Polycythemia vera results from abnormal red blood cell proliferation due to genetic mutations involving the Janus Kinase 2 (JAK2) gene. Due to over-production of red blood cells, patients with polycythemia vera have blood which is thicker than normal, potentially resulting in increased risks for thrombosis and reduction in blood flow.2 The average age at initial polycythemia vera diagnosis is 60-65 years old. The median overall survival for patients diagnosed with polycythemia vera is approximately 20 years.3

BESREMi is manufactured by PharmaEssentia, a growing biopharmaceutical innovator based in Taiwan. The FDA’s approval of BESREMi is based upon the results of the PEGINVERA study, a prospective, multicenter, single-arm trial of 7.5 years duration. This study demonstrated that BESREMi administration resulted in 61% of patients achieving a complete hematological response (CHR) during the treatment period defined as hematocrit <45% and no phlebotomy in the preceding 2 months, platelets < 400 x 109/L and leukocytes < 10 x 109/L, normal spleen size assessed by ultrasound and absence of thromboembolic events.4

BESREMi was approved with a boxed warning for risk of serious disorders including aggravation of neuropsychiatric, autoimmune, ischemic and infectious disorders. Please see accompanying full Prescribing Information, including Boxed Warning. For more information, visit www.BESREMi.com.

On November 18, 2021 City of Hope, a world-renowned research and treatment organization for cancer, diabetes and other life-threatening diseases, reported the opening of a first-in-human clinical trial evaluating the use of a cancer-killing oncolytic virus to treat patients with metastatic triple-negative breast cancer (Press release, City of Hope, NOV 18, 2021, View Source [SID1234595810]).

The City of Hope-developed therapy, CF33-hNIS-antiPDL1, is genetically engineered from a naturally occurring virus (chimeric oncolytic orthopoxvirus). The patents covering CF33-hNIS-antiPDL1 have been licensed to Imugene Limited (ASX:IMU), a company developing immunotherapies that seek to activate the immune system of cancer patients to treat and eradicate tumors. CF33-hNIS-antiPDL1 is designed to infect, replicate in and kill cancer cells while sparing healthy cells.

"The study is designed to determine the safety and optimal biological dose that may induce an immune response in triple-negative breast cancer tumors," said Yuan Yuan, M.D., Ph.D., associate professor in City of Hope’s Department of Medical Oncology & Therapeutics Research and principal investigator of the Phase 1 clinical trial. "Current approved therapies do not offer a cure for this aggressive type of breast cancer, which often becomes resistant to chemotherapy. Clinical trials like this one seek durable responses and better quality of life for patients."

The researchers seek to determine the appropriate dose of CF33-hNIS-antiPDL1 and ascertain if it is a safe and potentially effective treatment for patients with triple-negative breast cancer that is advanced or has spread to other places in the body. It will be tested in patients whose cancer has progressed through standard-of-care chemotherapy.

Triple-negative breast cancer affects about 15-20% of all breast cancer patients. It is a challenging disease to treat — most Food and Drug Administration-approved therapies prolong survival for a median of two years, Yuan said. Despite the recent FDA approval of targeted therapy for BRCA gene mutation (that is, immune checkpoint inhibitor pembrolizumab and Trop-2 antibody drug conjugate), the majority of patients continue to progress after the first two lines of therapy. There is an unmet need for patients whose triple-negative breast cancer has progressed despite previous treatment regimens.

The cancer killing effects of CF33 have been observed for the following cancer cell types in the preclinical setting: pancreatic, stomach, lung, ovarian and colon. Published preclinical data show that the CF33 oncolytic virus can increase the presence of immune checkpoint inhibitors, which can help enhance the immune system’s ability to do its job.

"It is an exciting time in immuno-oncology. Preclinical research has shown that this oncolytic virus can direct the killing of cancers and stimulate the immune system to enable further killing of cancers," said Yuman Fong, M.D., the Sangiacomo Family Chair in Surgical Oncology at City of Hope who developed CF33. "This trial is an important step forward."

The three-year trial seeks to enroll patients who have been diagnosed with recurrent metastatic triple-negative breast cancer who experienced disease progression after standard-of-care therapies. Study participants may receive a total of three cycles of six doses of the treatment through direct injection into the tumor.

Scientists will be able to say that the oncolytic virus activated the immune system against breast cancer if they note increased expression of checkpoint targets PD-1, PD-L1 or CTLA-4 and increased CD8+ immune cells. When there are more of these checkpoint targets, current approved and experimental therapies are better able to grab onto and unlock cancer cells to destroy them from the inside.

Through Epic’s Genomics module, Tempus has been paving the way with live EHR integrations that embed test ordering and discrete genomic data delivery into the existing clinical workflow, with 8 institutions already live and a number underway. Tempus’ initial work with Epic made it the first somatic sequencing lab in the country creating these types of integrations.

"Tempus understands our need for efficient, streamlined ordering and reliable discrete results all in one place so that we can promptly implement the actionable results for our patients," said Karen Huelsman, MS, LGC, Precision Oncology Lead at TriHealth Precision Oncology. "More than that, Tempus continually works with our precision oncology team to optimize the integration and apply Epic’s Genomics module components to fit our specific, changing needs."

Tempus is building on that existing work to accelerate and scale this endeavor. In 2022, Epic and Tempus expect to support large-panel genomic sequencing testing across the Epic network. This new capability is designed to reduce integration timelines from months to weeks and make it significantly easier for health systems to enable Tempus testing options within their Epic EHR.

"We realized that we could significantly reduce the amount of time physicians spend ordering Tempus’ smart diagnostics and viewing results at the point of care, ultimately freeing up more time for them to spend with their patients," said Terron Bruner, Chief Commercial Officer of Tempus. "Epic introduced the technology we needed to make these kinds of integrations not only possible, but also seamless for providers, like TriHealth, seeking these solutions."

"Our work with Tempus presents a tremendous opportunity to advance precision medicine by empowering providers and patients with insights from integrated genomic data," said Alan Hutchison, Vice President of Population Health at Epic. "Together we can deliver on the promise of precision medicine and positively impact early detection, treatment, and survival."

On November 18, 2021 Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) reported that the first patient was dosed in the global TROPION-Breast01 phase 3 trial evaluating the efficacy and safety of datopotamab deruxtecan (Dato-DXd), a TROP2 directed DXd antibody drug conjugate (ADC) being jointly developed by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN), in patients with hormone receptor (HR) positive, human epidermal growth factor 2 receptor (HER2) negative inoperable or metastatic breast cancer previously treated with chemotherapy (Press release, Daiichi Sankyo, NOV 18, 2021, View Source [SID1234595808]).

Breast cancer is the most common cancer worldwide with more than two million cases diagnosed in 2020, resulting in nearly 685,000 deaths globally.1 Approximately 70% of all breast cancers are considered HR positive, HER2 negative.2 For patients with HR positive, HER2 negative metastatic breast cancer that progresses on or is not suitable for hormone therapy-based regimens, current standard of care is single-agent chemotherapy, which demonstrates diminishing efficacy with each subsequent line of treatment.3

"There are no TROP2 directed therapies currently approved for HR positive, HER2 negative breast cancer and we are encouraged by the emerging clinical profile of datopotamab deruxtecan in patients with breast cancer," said Gilles Gallant, BPharm, PhD, FOPQ, Senior Vice President, Global Head, Oncology Development, Oncology R&D, Daiichi Sankyo. "TROPION-Breast01 is the first pivotal trial of datopotamab deruxtecan in breast cancer and the third pivotal study in our clinical development program, underscoring our efforts to accelerate development of this TROP2 directed ADC in breast and lung cancer."

"Most patients with HR positive, HER2 negative metastatic breast cancer will inevitably progress on available treatments, including hormonal therapy and standard of care chemotherapy. In this setting, the unmet need is high, and new therapeutic approaches are necessary to delay disease progression and extend survival," said Cristian Massacesi, MD, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca. "The TROPION-Breast01 trial will evaluate whether datopotamab deruxtecan may be a more effective treatment than chemotherapy for patients with previously treated HR positive, HER2 negative advanced breast cancer previously treated with one to two lines of chemotherapy."

About TROPION-Breast01
TROPION-Breast01 is a global, randomized, open-label, phase 3 trial evaluating the efficacy and safety of datopotamab deruxtecan (6 mg/kg) compared with investigator’s choice of chemotherapy (eribulin, capecitabine, vinorelbine or gemcitabine) in patients with inoperable or metastatic HR positive, HER2 negative breast cancer (per ASCO (Free ASCO Whitepaper)/CAP guidelines, on local laboratory results) who have progressed on or were not suitable for endocrine therapy and previously treated with one or two prior lines of systemic chemotherapy in the inoperable or metastatic setting.

The dual primary endpoints of TROPION-Breast01 are progression-free survival (PFS) assessed by blinded independent central review and overall survival. Secondary endpoints include PFS assessed by investigator, objective response rate, duration of response, disease control rate, and patient reported outcomes, as well as safety and pharmacokinetics.

TROPION-Breast01 will enroll approximately 700 patients at sites in Africa, Asia, Europe, North America and South America. For more information visit ClinicalTrials.gov.

About HR Positive, HER2 Negative Breast Cancer
Breast cancer is the most common cancer and is one of the leading causes of cancer-related deaths worldwide. More than two million cases of breast cancer were diagnosed in 2020, resulting in nearly 685,000 deaths globally.1 Approximately 5% to 10% of women diagnosed with breast cancer have metastatic disease at diagnosis, and up to 30% of women with early-stage breast cancer will develop metastatic disease.4

Approximately 70% of all breast cancers are considered HR positive, HER2 negative, meaning tumors test positive for estrogen and/or progesterone hormone receptors and negative for HER2.2 Current standard of care treatment for patients with HR positive, HER2 negative metastatic breast cancer that progresses on hormone therapy-based regimens is sequential single-agent chemotherapy. However, response rates are low with PFS ranging from 4 to 6.3 months with second-line chemotherapy, and 2.4 to 5.5 months with third-line chemotherapy.5,6,7,8 Data in subsequent lines of treatment show decreasing median PFS and OS with each further line of chemotherapy. There remains a need to improve outcomes including survival for patients living with advanced HR positive, HER2 negative breast cancer.9

About TROP2
TROP2 (trophoblast cell-surface antigen 2) is a transmembrane glycoprotein overexpressed in several types of solid tumors, including breast cancer.10 TROP2 expression has been detected in a wide range of breast cancer subtypes, including the HR positive, HER2 negative subtype.11,12 High TROP2 expression is an unfavorable prognostic factor for overall survival in all types of breast cancer.13 There are currently no TROP2 directed therapies approved for treatment of HR positive, HER2 negative breast cancer.

About Datopotamab Deruxtecan (Dato-DXd)
Datopotamab deruxtecan (Dato-DXd) is an investigational TROP2 directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC technology, datopotamab deruxtecan is one of three lead ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programs in AstraZeneca’s ADC scientific platform. Datopotamab deruxtecan is comprised of a humanized anti-TROP2 IgG13 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a topoisomerase I inhibitor payload, an exatecan derivative, via a tetrapeptide-based cleavable linker.14

A comprehensive development program called TROPION is underway globally with trials evaluating the efficacy and safety of datopotamab deruxtecan across multiple solid tumors, including non-small cell lung cancer (NSCLC), triple negative breast cancer (TNBC), HR positive/HER2 negative breast cancer, small cell lung cancer (SCLC), urothelial, gastric and esophageal cancer. Trials in combination with other anticancer treatments, such as immunotherapy, are also underway.

About the Daiichi Sankyo and AstraZeneca Collaboration
Daiichi Sankyo and AstraZeneca entered into a global collaboration to jointly develop and commercialize datopotamab deruxtecan in July 2020, except in Japan where Daiichi Sankyo maintains exclusive rights. Daiichi Sankyo is responsible for the manufacturing and supply of datopotamab deruxtecan.
