AI-enabled drug discovery company Insilico Medicine Ltd. has raised $60 million in a series D round to support expansion of its pipeline. The Hong Kong and New York-based company will use the proceeds to support clinical testing of its lead asset, a potential treatment for idiopathic pulmonary fibrosis (IPF), as well as the advancement of its Pharma.AI platform.

Biofourmis Inc. secured $300 million in a series D financing led by General Atlantic, with participation by CVS Health and existing investors. The round lifted the Boston-based company’s valuation to more than $1 billion and unicorn status, according to executives. Biofourmis will use the funds to drive next-stage growth in its virtual care offerings and digital therapeutics (DTx).

Valuations in the med-tech space lately call into question the old medical adage: “If you hear hoofbeats, think horses.” These days, you would be wise to consider unicorns in the differential diagnosis. Two new companies achieved the formerly rare status just this week. Viz.ai Inc.’s closing today of a $100 million series D financing propelled it into the stratosphere with a $1.2 billion valuation, joining Bostongene LLC which completed its own $150 million round Wednesday.

Ceros Capital Markets completed a $15 million series D funding round for Pristine Surgical LLC, its latest major investment in the medical device space. The funds will be used to advance the commercialization of Pristine’s single-use visualization platform for surgical and diagnostic endoscopic procedures.

It’s no mystery why Scipher Medicine Corp. successfully raised $110 million in a series D financing round to further develop the company’s precision medicine platform. The company aims to address one of most modern medicine’s most challenging enigmas: how to eliminate the cost and adverse effects associated with the prescription of expensive medications that provide life-changing outcomes for some and no benefit for others. The new funds boost Scipher’s total funding to $227 million, of which $192 million has come into the Waltham, Mass.-based company’s coffers in the last 12 months.

Sword Health Technologies Inc. slipped another $189 million into its coffers with an oversubscribed $163 million series D fundraising round that spilled into an additional $26 million secondary transaction. The enthusiasm for the round points to the keen interest in digital delivery of musculoskeletal (MSK) physical therapy, which has driven Sword and competitor Hinge Health Inc. both into rarified unicorn territory with valuations of $2 billion and $6.2 billion, respectively.

LONDON – Breath biopsy specialist Owlstone Medical Ltd. closed a $58 million oversubscribed series D, bringing the total raised by the company since its formation in 2016 to over $150 million. The money will support further development of tests for lung cancer, liver disease and respiratory disease, and of a new class of diagnostics, which rather than measuring endogenous markers of disease, involve administering chemical probes and assessing how they are metabolized.

In the largest private fundraising round for a U.S. medical device company in the past year, Imperative Care Inc. closed $260 million in a series D financing round on Thursday. The company also acquired its spinoff Truvic Medical Inc., a peripheral thrombectomy developer.
