The U.S. Preventive Services Task Force (USPSTF) appears on the verge of expanding colorectal cancer screening to individuals ages 45 to 49, based on its latest draft recommendations. If it does, Exact Sciences Corp. is ready. A study in Cancer Prevention Research demonstrated that the Madison, Wis.-based company's Cologuard multitarget stool DNA test had better than 95% specificity in individuals with nonadvanced precancerous lesions or negative findings on colonoscopy.

Liquid biopsy startup Delfi Diagnostics Inc. scooped up $100 million in a series A round led by Orbimed Advisors LLC. The company will use the funds to grow its team of cancer researchers and machine learning experts and to validate its next-generation blood-based testing technology in prospective clinical trials. Existing investors Menlo Ventures, Samsara Biocapital, Illumina Ventures, Av8 Ventures also participated in the round, along with new investors Foresite Capital, Northpond Ventures, Cowen Healthcare Investments and Rock Springs Capital.

Just a week into 2021 and Hologic Inc. is planning another acquisition. The company announced that it has agreed to acquire the molecular diagnostics testing company Biotheranostics Inc. for roughly $230 million cash up front. This comes on the heels of completing the acquisition of Somatex Medical Technologies GmbH for about $64 million. The acquisition of San Diego-based Biotheranostics is expected to close in February 2021, pending antitrust clearance.

A new imaging technology that uses transmission ultrasound to provide a 3D image of breast tissue outperformed traditional digital mammography in a recent retrospective analysis. The study findings could set the stage for the U.S. FDA to clear the technology for breast cancer screening in young, high-risk women.

Hologic Inc., which focuses on women’s health, said Jan. 4 that it has completed the acquisition of Somatex Medical Technologies GmbH for roughly $64 million. Based in Berlin, Somatex focuses on minimally invasive devices for tumor diagnostics, biopsy and interventional specialties. Somatex’s portfolio includes biopsy site markers and localization technologies, including Trumark markers. The company was previously owned by E-Med Solutions GmbH, a group of investors led by German private equity firm Westlake Partners.

While several companies are looking to help recurrent glioblastoma patients, Carthera SAS has taken a step forward by bringing its Sonocloud-9 device into a phase I/II clinical trial. Northwestern University in Chicago will collaborate with the company in the trial, which is expected to enroll up to 39 patients. The first patient already has been treated.

Scientists at Duke University School of Medicine in Durham, N.C., have developed a small-molecule inhibitor of the cellular stress-protective transcription factor, heat-shock factor 1, which showed developmental promise against treatment-resistant prostate cancer and other cancers. The small molecule, Direct Targeted HSF1 InhiBitor (DTHIB), may also be a useful research tool for investigating the regulation and role of HSF1 in basic stress biology and in cancer.

Clinical-stage oncology company Nuview Life Sciences Inc. is developing a cancer diagnostic test and treatment delivery system that could reduce the need for costly, less accurate tests and surgical biopsies. The binary – yes/no – test employs a proprietary peptide construct, NV-VPAC1, that targets a specific receptor, called vasoactive intestinal peptide receptor type 1 (VPAC1), that is overexpressed on the surface of cancer cells.

Bayer Corp. and Veracyte Inc. are collaborating in the thyroid cancer space, with an eye toward identifying underlying genomic drivers, including NTRK gene fusions, within patients’ tumors. South San Francisco-based Veracyte offers the Afirma Genomic Sequencing Classifier (GSC) and Xpression Atlas (XA), which aims to help physicians in terms of thyroid cancer diagnosis and individualized care.

Researchers at Thomas Jefferson University have found that using ultrasound to pop microbubbles already present in a contrast agent nearly doubled liver tumor response to transarterial radioembolization. The procedure raised no safety concerns and increased the likelihood of patients receiving a liver transplant.
