FDA Moves Closer to Standardized Testing for Asbestos in Talc

The U.S. Food and Drug Administration moved closer on Tuesday to formulating standardized testing of talc-based products for the presence of toxic asbestos fibers. Experts from eight different federal agencies explained earlier recommendations at a day-long hearing. The session also featured input from 25 members of the public, which included industry representatives, consumer advocates and testing experts. “Standards are needed,” said Dr. Paul Howard, FDA Office of Regulatory Science, during his presentation. “They just don’t exist at this time.” Dr. Linda Katz, director of the FDA Office of Cosmetics and Color, said the next step will be producing a white paper after reviewing all recommendations as an authoritative guide on the issue. “There are challenges in establishing the most suitable approach to testing for asbestos in cosmetic products,” Katz said. “We know there is confusing terminology. Data from different labs suffers from a lack of procedural standardization. There is a need for standardization.” FDA Pushed by Recent Findings of Asbestos This was the first official FDA hearing on asbestos in talc in almost 50 years. The FDA has intensified its oversight efforts after finding traces of asbestos mixed with talc in several different cosmetics and powders in the last two years. In October 2019, the agency found asbestos fibers in one bottle of Johnson’s Baby Powder, leading to a voluntary recall of the prod...

The U.S. Food and Drug Administration found asbestos-contaminated talc in nine of the 52 cosmetic products tested during its year-long study released this week. The products with asbestos were recalled at various times throughout the past year when individual results were obtained and the public was notified. Monday’s announcement by the FDA was labeled a Constituent Update and Final Report. It also included those products that showed no trace of contamination. AMA Analytical Services Inc. in Lanham, Maryland, performed all testing for the FDA, using polarized light microscopy and transmission electron microscopy, cu...

Doctors at the Swiss Group for Clinical Cancer Research in Zurich, Switzerland, have uncovered a novel, anti-tumor compound that could become a needed second-line treatment for pleural mesothelioma cancer. Their recent multicenter phase II clinical trial conducted in Switzerland and Italy revealed the safety and efficacy of lurbinectedin, a synthetically produced agent that inhibits the growth of mesothelioma cells. “We believe this could represent a new treatment option for pleural mesothelioma,” Dr. Yannis Metaxas, oncologist at Kantonsspital Graubunden outside Zurich, told The Mesothelioma Center at Asbestos...

A new 33-patient case study published in the Journal of Occupational and Environmental Medicine provides some of the strongest proof yet that exposure to asbestos-tainted talcum powder may cause malignant mesothelioma, a rare and deadly cancer that affects tissues lining internal organs. This isn’t only an important scientific discovery—it could also give new ammunition to plaintiffs in the thousands of cases brought against brands selling talcum-powder-based products alleged to cause cancer, like Johnson &Johnson’s Baby Powder. “It’s very, very hard, in general, to prove exactly what caus...

A mesothelioma patient at West Cancer Center in Memphis, Tennessee, is the first in the country to use NovoTTF-100L, a noninvasive electric therapy treatment, since its approval by the U.S. Food and Drug Administration in May. The FDA’s approval of Novocure’s Tumor Treating Fields device for the treatment of mesothelioma marked the first new FDA-approved treatment option for the rare asbestos-related cancer in more than 15 years. NovoTTF-100L uses a low-voltage electrical field that is distributed with three pads attached to the front and back of a person’s chest. The electrical current is designed to di...

AbstractBackgroundTumor Treating Fields (TTFields) are a non-invasive, antimitotic therapy delivered to the tumor via transducer arrays applied to the skin at tumor site. The only TTFields-related adverse event (AE) reported in clinical trials was localized dermatitis beneath the arrays. The safety of TTFields has also been investigated in glioblastoma, non-small-cell lung cancer (NSCLC), mesothelioma, pancreatic and ovarian cancer. This meta-analysis reported AEs in clinical studies with TTFields torso delivery.Methods192 patients from 4 pilot studies were included in the analysis: EF-15 (n  = 41, advanced N...

A research team from the Duke University Medical Center and the Massachusetts Institute of Technology has uncovered a new compound with potential to make chemotherapy more effective in treating various cancers. The small-molecule inhibitor drug — JH-RE-06 — showed an ability to better-sensitize tumors to Cisplatin, the popular chemotherapy drug most often used for mesothelioma cancer patients. When combined with Cisplatin, the drug also showed an ability to prevent those tumor cells from becoming treatment resistant, a common problem with this rare cancer caused by asbestos exposure. The research was done on l...

Sarah Cannon Research Institute in Nashville, Tennessee, and MD Anderson Cancer Center in Houston have opened a much-anticipated clinical trial involving a novel T-cell therapy for patients with mesothelioma. The two institutions are establishing dosage levels and measuring efficacy of TC-210, a type of immunotherapy that targets mesothelin, a cell surface protein highly expressed in several cancers. The study also is open to patients with certain types of bile duct, ovarian and non-small cell lung cancer. Participation is based upon individual levels of mesothelin expression. Researchers at the two centers are hoping to ...

More than a dozen senior officials and experts at the Environmental Protection Agency urged the EPA to ban asbestos outright, a new report shows. Two internal memos obtained by the Asbestos Disease Awareness Organization and shared with the New York Times reveal the EPA’s own scientists and lawyers advised the agency to issue a complete ban of asbestos instead of the recent regulations that only restricted its domestic use. In the memos, dated Aug. 10, 2018, EPA staff members wrote that the agency “should seek to ban all new uses of asbestos because the extreme harm from this chemical substance outweighs any ...

This study is an important step forward in highlighting C1q as a new prognostic candidate biomarker for a range of carcinomas. Methods Oncomine Database Analysis The expression levels of C1QA, C1QB, and C1QC genes in various carcinomas were analyzed using Oncomine (www.oncomine.org), a cancer microarray database and web-based data mining platform from genome-wide expression analyses (22, 23). We compared the differences in mRNA level between normal tissue and carcinoma. The mRNA expression levels in neoplastic tissues compared to the healthy tissues were obtained as the parameters of p-value 2, and gene ranking in the t...
