Many writers have attempted to divide Next Generation Sequencing into Second Generation Sequencing and Third Generation Sequencing. Personally, I think it isn't helpful and just confuses matters. I'm not the biggest fan of Next Generation Sequencing (NGS) to start with.

Most cases of cervical cancer (85% in 2012) happen to women in low- or middle-income countries. That's why increasing vaccine coverage and screening is important if we want to eliminate cervical cancer worldwide, not just in wealthy countries.

An HPV vaccine has been available to girls aged 11-13 in the UK since 2008 as well as some older girls as part of a catch-up programme. And it has led to a dramatic reduction in HPV infection in this age group. Figures released last year by Public Health England suggest there’s been an almost 90% reduction HPV 16 and 18 infections in young women following vaccination.

Foundation Medicine, however, was also among those that expressed concerns with the unintended consequences relating to the impact on market competition, citing hindered innovation efforts. Another commenter with these concerns was AstraZeneca, which noted that “diagnostics manufacturers may be disincentivized to bring a new test to market if an existing test applies to full class.”

By imposing unnecessary clinical testing requirements in some cases, the authors’ proposal would make some beneficial devices less accessible to patients without good reason. As a result, patients would be harmed. The authors tout the benefits of their proposals but fail to address the possible costs.

Geneticist Mary-Claire King, who discovered the BRCA mutations and their link to breast cancer risk in 1990, said she'd like every woman to be offered complete sequencing of BRCA1 and BRCA2 as part of routine medical care. She called the new recommendations "short-sighted" and "not based on the most recent data" and said they "could cost lives."

The USPSTF recommends against routine screening, genetic counseling, or genetic testing for women whose family or personal history or ethnicity or ancestry is not associated with an increased risk for potentially harmful mutations in the BRCA1 or BRCA2 genes.

In a study published in Nature Cell Biology, a research team led by Dr. Ghajar showed in mice that, by disrupting the relationship between breast cancer cells that had spread to the bone and the normal cells surrounding them, they could make the hidden cancer cells sensitive to treatment. This was true whether the cancer cells were dividing or dormant.

The MGH-led study – part of a larger, open-label clinical trial of sacituzumab govitecan against several types of advanced cancer – enrolled 108 patients with triple-negative breast cancers, all of whom had received several prior treatments, between June 2013 and February 2017. Treatment with sacituzumab govitecan produced a treatment response in 33 percent of patients, and responses lasted an average of 7.7 months.

While a significant reduction in risk of venous thromboembolism was observed during the on-treatment period, the study did not find a significant impact on its primary outcome of venous thromboembolism during the first 180 days, during which time many patients came off the study drug to a similar extent in both the intervention and placebo arms.

The drug is a fusion of an antibody that recognizes a protein expressed by breast cancer cells known as trop2 and the metabolite of an established chemotherapy drug (irinotecan), SN-38. The antibody delivers SN-38 directly to the cancer cell.

The team’s analysis showed that genes involved in oxidative phosphorylation were upregulated in brain metastases, leaving those tumors reliant on that form of metabolism. Previous research by their team and others has also shown that oxidative phosphorylation promotes resistance to immunotherapies and targeted therapies.

While the two FDA-approved cancer CAR T treatments, Novartis’ Kymriah and Gilead's Yescarta, are made from autologous T cells taken directly from patients, Allogene is investigating the use allogeneic T cells that come from donors and can be stored for so-called “off the shelf” use.

When Keytruda won that nod late last year, researchers noted that patients with advanced HCC have few options. That’s one reason why a 17% response rate was enough to persuade the FDA to award Keytruda its accelerated approval.
|
|
|
|
|
|
|
|
|
|

The clinical failure poses a broader question of whether the FDA would issue a warning or caution against use of Keytruda as a second-line treatment for HCC.

Xencor didn’t have the best start to 2019—in January, its partner Novartis returned the rights to a bispecific antibody it had licensed as part of a 2016 deal worth up to $2.41 billion. Now, a second asset from that deal, in development for acute myeloid leukemia (AML), has hit a snag in the form of a partial clinical hold from the FDA.

TIBSOVO® is a first-in-class, oral, targeted inhibitor of mutant IDH1. The sNDA submission is based on results from the untreated AML patients from the Phase 1 dose-escalation and expansion study of ivosidenib in patients with newly diagnosed AML ineligible for standard treatment.

One patient experienced cytokine release syndrome (CRS) after their first dose, the treatment of which was complicated by the patient's decision to withdraw care. One patient developed acute pulmonary edema following several doses of XmAb14045.
|

|
|
|
|
|
|
|
|
|
Now you can expect plenty of more questions about what kind of safety issues these bispecifics pose as developers race each other to the finish line. That could be especially troubling for Xencor, particularly after J&J dropped it drug talacotuzumab (JNJ-56022473/CSL362) for acute myeloid leukemia in 2017.

This flexible way of paying for cancer medicines, known as outcome-based payment (OBP), would mean a drug’s price could be adjusted based on how well it works for patients in the NHS. For example, the NHS could pay the company less for a drug that doesn’t work as well as expected, but more if it does.

Indeed, one of the most pressing issues in American medicine is how to ensure that all populations, in every community, derive the benefit from scientific research that has already been completed. Addressing these questions from the perspective of health care delivery is necessary to accelerate the decline in cancer mortality that began in the early 1990s.

It said on Wednesday that “decades of independent tests by regulators and the world’s leading labs prove Johnson & Johnson’s baby powder is safe and asbestos-free, and does not cause cancer.”
