THE RUNDOWN
1

Cyllene Therapeutics, a Paris- and Beverly Hills-based biotech formerly known as EG 427, closed a €33 million (~$36M) Series C co-led by GordonMD Global Investments and Merck Ventures, the venture arm of Merck KGaA

2

The financing advances clinical development of EG110A, Cyllene's lead candidate using an engineered, non-replicating HSV-1 viral vector to deliver DNA medicine for severe neurogenic bladder conditions

3

Additional participants include Bpifrance's InnoBio 3 fund, T. Andera Partners and Lamond Ventures, reflecting continued European public and private co-investment in gene-therapy platforms

4

The round also funds expansion of Cyllene's proprietary HERMES non-replicating HSV-1 platform, positioning the company in the same viral-vector gene-therapy category as larger players like uniQure and Sarepta

A €33M round is small by 2026 AI-headline standards, but Merck KGaA's strategic money validating a non-replicating HSV-1 platform matters more than the check size -- pharma corporates don't co-lead Series Cs on unproven vector platforms out of politeness. Worth watching whether Cyllene's HERMES platform gets licensed out to a bigger partner before EG110A even reaches Phase 3 data.

Cyllene Therapeutics, a Paris- and Beverly Hills-based biotech formerly known as EG 427, announced the close of a €33 million (roughly $36 million) Series C on July 7, co-led by GordonMD Global Investments and Merck Ventures, the venture arm of German pharmaceutical giant Merck KGaA.

The financing will advance clinical development of EG110A, Cyllene's lead DNA-medicine candidate for severe neurogenic bladder conditions, built on the company's proprietary HERMES platform -- an engineered, non-replicating HSV-1 viral vector designed to deliver therapeutic genes directly to affected tissue without the safety concerns of a replicating virus.

“Additional participants in the round include Bpifrance's InnoBio 3 fund, T.”

Additional participants in the round include Bpifrance's InnoBio 3 fund, T. Andera Partners and Lamond Ventures -- a syndicate that leans heavily on European public and quasi-public biotech capital, a pattern that has become more common as private gene-therapy funding has tightened globally over the past two years.

The round places Cyllene in the same viral-vector gene-therapy category as larger, more clinically advanced players like uniQure and Sarepta Therapeutics, though at an early enough stage that Merck KGaA's strategic participation -- rather than the round size itself -- is the more meaningful signal of pharma-industry validation for the underlying HERMES platform.
