Meta Pharmaceuticals Inc. has raised $15 million in seed and pre-series A rounds in six months for the pipeline and AI platform development. Shenzhen, China-based Meta Pharma plans to use the new funds to support its three candidates to enter clinical trials, as well as the development of its Meta-map platform for pipeline expansion.

Microtransponder Inc. raked in $53 million in an oversubscribed series E round that exceeded its best previous fundraising by nearly 500% and brought the company’s total funds raised to date to $93 million. The new money will be used to commercialize the Vivistim paired VNS system, which received premarket approval in 2021 as what the FDA called the “first stroke rehabilitation option using vagus nerve stimulation.”

Aerin Medical Inc.’s funding nosed up to $190.5 million with its latest venture capital round, which brought in $60 million in fresh cash. The provider of noninvasive solutions for chronic nasal conditions plans to use the funds to ramp up commercialization and expand market access to its Vivaer and Rhinaer products. New investor Ally Bridge Group led the round with support from returning major investors KCK Medtech, Questa Capital and Orbimed.
