Startup firm Dyno Therapeutics Inc. is attempting to engineer a new generation of adeno-associated virus (AAV) capsids by navigating its way across what it calls the “capsid fitness landscape,” in order to optimize the key parameters that affect capsid performance: production, delivery efficiency, biodistribution, immunogenicity and thermostability.

BEIJING – Infection diagnostics specialist Genskey Technologies Co. Ltd., of Beijing, closed a series B financing round to secure ¥100 million (US$14 million) to advance pathogen testing using next generation sequencing. The series B round was joined by SB China Capital, Shanghai Lin Chong Investment Management, and Juyuan Capital.

The U.S. FDA has granted breakthrough device designation for Righteye LLC’s eye movement-tracking vision system as a test for Parkinson’s disease. Developed by researchers at PADRECC and Virginia Commonwealth University with funding from the Michael J. Fox Foundation, and licensed to Righteye in 2016, the test requires patients to sit in front of an all-in-one tablet-looking device and follow a series of moving targets. The goal is to identify ocular tremors, a persistent issue with Parkinson’s patients that prevents steady fixation on objects and images. The noninvasive test, which measures an individual’s ability to follow objects on a screen, could help doctors not only confirm the difficult-to-diagnose disease, but also detect it at earlier stages.

Menlo Park, Calif.-based startup Tusker Medical Inc. has received U.S. FDA approval to market its breakthrough-designated system for inserting tympanostomy tubes into the eardrum to treat recurrent ear infections. The Tubes Under Local Anesthesia (Tula) system is the first delivery system for tympanostomy tubes, commonly known as ear tubes, that can be performed in young children under local anesthesia in a doctor’s office. The Tula system consists of the ionic anesthetic Tymbion, Tusker Medical tympanostomy tubes and several devices for inserting the anesthetic and tubes into the ear drum. A low-level electrical charge delivers the anesthesia to the eardrum prior to tube placement, allowing for quick and needle-free numbing of the tympanic membrane.

BEIJING – Shenzhen-based Xbiome Co. Ltd., said to be China’s first AI-based microbiome drug development company, closed a series B financing round to pocket ¥100 million (US$14 million).

Radiologist burnout is a common problem. To combat this issue, Berkeley, Calif.-based Rad AI has launched with a $4 million seed round led by Gradient Ventures, Google's AI-focused venture fund. Other participants in the round were UP2398, Precursor Ventures, GMO Venture Partners, Array Ventures, Hike Ventures, Fifty Years VC and various angels.
