Researchers Create Embryoids Using Stem Cells

BioSpace | July 02, 2019

Much of what happens as a human embryo develops is unknown. Its been defined in animal models, but not in humans. Much of the reason for that is related to ethical limitations on what type of research can be conducted on human embryos. There is a ban, which is called the 14-day rule, on conducting experiments on real human embryos after 14 days of growth. Researchers at Rockefeller University appear to have found a way to work around that ethical limitation, although it brings its own set of concerns with it. The scientists, led by molecular biologist Ali Brivanlou, used human embryonic stem cells to develop living models of human embryos that could be studied in the laboratory. The three-dimensional model of a human epiblast had the size, cell orientation and gene expression roughly equivalent to a day 10 human epiblast. We came up with a model of human embryos that are developed outside of the womb and is not the product of the sperm and the eggs but is the product of human embryonic stem cells that self-organize into complicated structures, Brivanlou told NPR.

Puma Biotech Publishes Alisertib Phase II Trial Results in JAMA Oncology

Puma Biotechnology, Inc. | March 16, 2023

Puma Biotechnology, Inc., a biopharmaceutical company, recently announced the online publication of the Phase II TBCRC041 randomized clinical trial results in JAMA Oncology. The trial investigated the use of alisertib, an adenosine triphosphate–competitive and reversible inhibitor of aurora kinase A, alone or in combination with fulvestrant in postmenopausal women with endocrine-resistant, HER2-negative metastatic breast cancer who were previously treated with fulvestrant. The Phase II randomized clinical trial was conducted via the Translational Breast Cancer Research Consortium and included patients previously treated with CDK 4/6 inhibitors and everolimus. The trial enrolled 91 evaluable patients, with baseline characteristics balanced between the two arms of the trial. However, more patients in the alisertib plus fulvestrant arm had previously received chemotherapy for metastatic disease (47.8% in the alisertib alone arm vs. 68.9% in the alisertib plus fulvestrant arm). In each arm of the trial, all patients had earlier been treated with CDK 4/6 inhibitors. Everolimus was previously administered to 37% of patients in the alisertib alone arm and 57.8% in the alisertib plus fulvestrant arm. The trial's efficacy results indicated that nine partial responses were observed in the 46 evaluable patients in the alisertib alone arm, leading to an overall response rate of 19.6%. The median duration of response was 15.1 months, with a clinical benefit rate of 41.3% at 24 weeks. The projected median progression-free survival (PFS) was 5.6 months. Nine of the 45 evaluable patients in the alisertib plus fulvestrant arm of the study responded, for an overall response rate of 20.0%. There was one patient who had a complete response and eight patients who showed partial responses. The median duration of response was 8.5 months, with a clinical benefit rate of 28.9% at 24 weeks. The median PFS was expected to be 5.4 months. The most prevalent grade 3 or higher adverse events in the alisertib alone arm of the trial were neutropenia (43.4%), anemia (19.6%) and leukopenia (17.4%). The most prevalent grade 3 or higher adverse events in the alisertib plus fulvestrant arm of the study were neutropenia (42.2%), leukopenia (31.1%), lymphopenia (15.6%), fatigue (11.1%), and anemia (8.9%).

Mission Bio Develops Single-Cell Solution to Address Challenges in Genome Editing

PR Newswire | May 12, 2023

Mission Bio, the single-cell DNA and multi-omics company, announced today the Tapestri® Genome Editing Solution, an end-to-end product for genome editing analysis. The product will be previewed next week at the American Society of Gene and Cell Therapy Conference (ASGCT) 26th Annual Meeting. By enabling robust single-cell insights impacting both efficacy and safety, the solution will be a powerful analytical tool for developing the next generation of gene-edited therapies. The first CRISPR-modified therapy is now under regulatory review, and many similar cell-based therapies are expected to follow for multiple intractable diseases. However, genome editing can result in complex, heterogeneous mixtures of edits that make it challenging to apply a level of process control over genome-edited cell products. The Tapestri® Genome Editing Solution addresses these challenges by measuring gene editing outcomes at single-cell resolution, capturing the co-occurrence of on- and off-target edits, as well as the zygosity of edits, which conventional bulk analyses cannot. Additionally, this analysis can be completed within days by processing thousands of cells at a time without any prior selection, while conventional analytical methods require months for clonal outgrowth. An early iteration of the Tapestri® Genome Editing Solution is currently being tested by key genome editing researchers and leading cell therapy developers in academia and industry, who are providing vital feedback on the analysis. Mission Bio recently collaborated with the National Institute of Standards and Technology (NIST) in the Genome Editing Consortium, which provided qualified samples to collaborators to assess technologies that report variant size and frequency within a mixed cell population. Samantha Maragh, NIST Genome Editing Program Leader, will present results of the study at 12:00 p.m. PT on May 17 (Poster 533) at the ASGCT Annual Meeting. "We look forward to pulling back the curtain on our end-to-end Genome Editing Solution at ASGCT," said Todd Druley, MD, PhD, Chief Medical Officer at Mission Bio. "The data acquired under the Genome Editing Consortium further demonstrates the Tapestri® Platform's potential as a standard analysis tool within the genome editing community. Given the heterogeneous results of gene editing strategies, there is a great need to address both industry and regulatory genome editing concerns with a consistent and highly precise technology for accurately measuring gene editing outcomes, and our new offering will be a complete solution to do just that."
