ATG-010 is the first approved SINE compound in the world. It induces the apoptosis of cancer cells in vitro and in vivo by causing the nuclear storage and activation of tumor suppressor proteins and other growth-regulating proteins, and by down-regulating the intracytoplasmic levels of various oncogenic proteins while normal cells are not affected. The US Food and Drug Administration (FDA) has approved ATG-010 (selinexor) as a novel treatment in three indications within eighteen months. Five ATG-010 regimens for patients with multiple myeloma or diffuse large B-cell lymphoma have also been added to the National Comprehensive Cancer Network (NCCN) Guidelines. Antengene has completed patient enrollment for the registrational clinical trial in rrMM in mainland China and has submitted NDAs for ATG-010 in five APAC markets including Australia, South Korea and Singapore over the past six months.

"ATG-010 is a novel option for the treatment of rrMM and we are pleased that it has been granted priority review by the NMPA. The target of ATG-010, XPO1, is the only proven nuclear export protein target in clinical development and we believe that ATG-010 has potential to meet the huge unmet medical needs in hematological malignancies and solid tumors." said Dr. Jay Mei, M.D., PhD., Founder, Chairman and CEO of Antengene. "rrMM still remains an incurable disease and we are excited that more patients may have access to ATG-010 earlier in the course of their treatment. We look forward to working closely with the regulatory authority to move this important indication for ATG-010 towards approval."

"Working Procedures for Priority Review and Approval of Drug Marketing Authorization (Interim)" has been issued by the NMPA on July 7, 2020 to expedite the development and registration of drugs that provide significant clinical value. With the effective implementation of these procedures, the regulatory authority will expedite the evaluation and approval of novel drugs through a priority review pathway and facilitate earlier access of these drugs to patients in China.

About ATG-010 (selinexor, XPOVIO)

ATG-010 (selinexor, XPOVIO), a first-in-class and only-in-class oral selective inhibitor of nuclear export (SINE) compound discovered and developed by Karyopharm Therapeutics Inc. (NASDAQ: KPTI), is currently being developed by Antengene, which has the exclusive development and commercial rights in certain Asia-Pacific markets, including Greater China, South Korea, Australia, New Zealand and the ASEAN countries.

In July 2019, the US Food and Drug Administration (FDA) approved selinexor (XPOVIO) in combination with low-dose dexamethasone for the treatment of relapsed/refractory multiple myeloma (rrMM) and in June 2020 approved selinexor (XPOVIO) as a single-agent for the treatment of relapsed/refractory diffuse large B-cell lymphoma (rrDLBCL). In December 2020, selinexor (XPOVIO) also received FDA approval as a combination treatment for multiple myeloma after at least one prior therapy. A Marketing Authorization Application (MAA) has also been submitted to the European Medicines Agency (EMA) with a request for conditional approval of selinexor in this same rrMM indication. Selinexor (XPOVIO) is so far the first and only oral SINE compound approved by the FDA and is the first drug approved for the treatment of both MM and DLBCL. Selinexor (XPOVIO) is also being evaluated in several other mid-and later-phase clinical trials across multiple solid tumor indications, including liposarcoma and endometrial cancer. In November 2020, at the Connective Tissue Oncology Society 2020 Annual Meeting (CTOS 2020), Antengene’s partner, Karyopharm, presented positive results from the Phase 3 randomized, double blind, placebo controlled, cross-over SEAL trial evaluating single agent, oral selinexor (XPOVIO) versus matching placebo in patients with liposarcoma. Karyopharm also announced that the ongoing Phase 3 SIENDO trial of selinexor (XPOVIO) in patients with endometrial cancer passed the planned interim futility analysis and the Data and Safety Monitoring Board (DSMB) recommended the trial should proceed as planned without any modifications. Top-line SIENDO trial results are expected in the second half of 2021.

Odonate Therapeutics Announces Financial Results for the Three and Twelve Months Ended December 31, 2020

On February 23, 2021 Odonate Therapeutics, Inc. (NASDAQ: ODT), a pharmaceutical company dedicated to the development of best-in-class therapeutics that improve and extend the lives of patients with cancer, reported financial results for the three and twelve months ended December 31, 2020 (Press release, Odonate Therapeutics, FEB 23, 2021, View Source [SID1234575486]).

As of December 31, 2020, Odonate had $157.3 million in cash, compared to $180.5 million as of December 31, 2019. This decrease in cash resulted primarily from cash used in operating activities for the twelve months ended December 31, 2020 of $113.1 million, partially offset by the receipt of $87.4 million of net proceeds from Odonate’s September 2020 underwritten public offering. Odonate’s net loss for the three and twelve months ended December 31, 2020 was $32.3 million and $126.4 million, or $0.87 and $3.84 per share, respectively, compared to $27.9 million and $111.8 million, or $0.91 and $4.05 per share, respectively, for the same periods in 2019.

"Positive results of CONTESSA, Odonate’s Phase 3 study investigating tesetaxel as a potential treatment for patients with metastatic breast cancer, were recently presented at the 2020 San Antonio Breast Cancer Symposium," said Kevin Tang, Chief Executive Officer of Odonate. "We continue to plan to submit a New Drug Application for tesetaxel to the FDA in mid-2021."

About Tesetaxel

Tesetaxel is an investigational, orally administered chemotherapy agent that belongs to a class of drugs known as taxanes, which are widely used in the treatment of cancer. Tesetaxel has several properties that make it unique among taxanes, including: oral administration with a low pill burden; a long (~8-day) terminal plasma half-life in humans, enabling the maintenance of adequate drug levels with relatively infrequent dosing; no history of hypersensitivity (allergic) reactions; and significant activity against chemotherapy-resistant tumors. In patients with metastatic breast cancer (MBC), tesetaxel was shown to have significant, single-agent antitumor activity in two multicenter, Phase 2 studies. Tesetaxel currently is the subject of three studies in MBC, including a multinational, multicenter, randomized, Phase 3 study in patients with MBC, known as CONTESSA. Positive results of CONTESSA were presented at the 2020 San Antonio Breast Cancer Symposium in December.

About CONTESSA

CONTESSA is a multinational, multicenter, randomized, Phase 3 study of tesetaxel, an investigational, orally administered taxane, in patients with metastatic breast cancer (MBC). CONTESSA is comparing tesetaxel dosed orally at 27 mg/m2 on Day 1 of a 21-day cycle plus a reduced dose of capecitabine (1,650 mg/m2/day dosed orally for 14 days of a 21-day cycle) to the approved dose of capecitabine alone (2,500 mg/m2/day dosed orally for 14 days of a 21-day cycle) in 685 patients randomized 1:1 with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)‑negative MBC previously treated with a taxane in the neoadjuvant or adjuvant setting. Capecitabine is an oral chemotherapy agent that is considered a standard-of-care treatment in MBC. Where indicated, patients must have been treated with endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor. The primary endpoint is progression-free survival (PFS) as assessed by an Independent Radiologic Review Committee (IRC). The secondary endpoints are overall survival (OS), objective response rate (ORR) as assessed by the IRC and disease control rate (DCR) as assessed by the IRC.

Positive results of CONTESSA were presented at the 2020 San Antonio Breast Cancer Symposium in December. The primary endpoint was met: median PFS was 9.8 months for tesetaxel plus a reduced dose of capecitabine versus 6.9 months for the approved dose of capecitabine alone, an improvement of 2.9 months. The risk of disease progression or death was reduced by 28.4% (hazard ratio=0.716 [95% confidence interval [CI]: 0.573‑0.895; p=0.003]). Neutropenia was the most common Grade ≥3 treatment‑emergent adverse event.

Biocept and Protean BioDiagnostics Establish Research Collaboration to Demonstrate Advantages of Biocept’s Target Selector™ Assay Kit for Non-Small Cell Lung Cancer Patients

On February 23, 2021 Biocept, Inc. (Nasdaq: BIOC), a leading provider of molecular diagnostic assays, products and services, reported that it will collaborate with Protean BioDiagnostics Inc. to research the ability of Biocept’s Target Selector molecular assay to determine EGFR status in non-small cell lung cancer (NSCLC) patients (Press release, Biocept, FEB 23, 2021, View Source [SID1234575485]). The research will be conducted in an independent pathology laboratory setting.

Protean BioDiagnostics also expects to validate the analytical performance of a laboratory developed test (LDT) based on Biocept’s EGFR assay test kit in accordance with the requirements of the College of American Pathologists (CAP) validation process.

Biocept’s novel molecular assay kit, available for research-use-only and with CE-IVD mark, enables molecular laboratories around the world to utilize its Target Selector platform to analyze both formalin-fixed paraffin-embedded (FFPE) tissue samples and circulating tumor DNA (ctDNA) from biological fluids. Target Selector leverages patented Switch-Blocker technology to enrich specimens for mutations of interest and block DNA amplification from normal cells, requiring less tumor sample and resulting in higher assay sensitivity than most commercial assays. Biocept’s molecular assays have been validated for the detection of frequent oncogenic mutations EGFR, KRAS and BRAF, which are among the most frequently evaluated biomarkers for lung cancer and melanoma.

"We are pleased to collaborate with Biocept to demonstrate the potential of its assay in determining EGFR status," said Anthony M. Magliocco, MD, President and CEO of Protean BioDiagnostics. "Obtaining adequate tissue sample for genomic profiling continues to be a challenge in first-line therapy selection for patients with NSCLC. Target Selector EGFR assays require 50% less tumor input sample than most commercial assays, making it a potentially powerful tool in helping qualify more patients for targeted tyrosine kinase inhibitor, or TKI, therapy. This potential advantage is coupled with previous studies demonstrating Target Selector assays’ best-in-class low-end limit of detection of mutations in both FFPE and liquid biopsy samples."

"Protean BioDiagnostics is the ideal partner for this collaboration, as we share a joint commitment to advancing the best possible care for patients with cancer," said Michael Nall, Biocept President and CEO. "Protean has extensive experience working with some of the world’s leading biotechnology companies. Together, our goal is to demonstrate how Target Selector assays can help physicians create more personalized, responsive treatment plans for their patients."

About Target Selector Molecular Assay Kits
Target Selector molecular assay kits are marketed for research-use-only (RUO) in the U.S. and CE-IVD in the European Union and other CE Mark geographies, offering industry-leading sensitivity for the detection of mutations/variants of interest in both FFPE and ctDNA. Target Selector assays with Switch-Blocker technology can also provide results with smaller DNA inputs (minimum 4.6 ng) than most tissue-based assays, allowing laboratories to get results even with small amounts of tissue. These capabilities should allow laboratories to eliminate macro-dissection of tumor blocks, potentially resulting in major workflow improvements and cost savings.

Target Selector assays can be used in combination with a variety of low-cost analytical platforms including qPCR, Sanger sequencing, microarrays, and mass-spectrometry, in addition to next generation sequencing. Target Selector kits (RUO and CE-IVD) offer high content per assay, which can reduce costs by selectively amplifying multiple mutations/variants in hot-spot regions of interest in a single reaction. All Target Selector assays are quantitative.

Target Selector molecular assay kits (RUO and CE-IVD) are currently available for EGFR and BRAF mutations. Additional test kits for other oncogene mutations are planned for launch in the future.
