Valneva (VALN) Up on Antibody Persistence Data on Chikungunya Jab

Valneva SE VALN announced positive 12-month antibody persistence data following vaccination with a single dose of its chikungunya vaccine candidate, VLA1553.

The antibody persistence study enrolled 363 healthy adult participants and followed them from month six to month 12 after vaccination. Data from the same showed that 99% of participants retained neutralizing antibody titers above the seroresponse threshold following a single dose of the chikungunya vaccine after 12 months – the primary endpoint.

Shares of Valneva were up 5.4% on Monday following the announcement of the news. The stock, however, has plunged 73.2% so far this year compared with the industry’s decline of 43.5%.

VALN announced positive immunogenicity and safety data from the phase III study, VLA1553-301 in March 2022.

Per the company, after this positive data, management decided to set up an antibody persistence study – VLA1553-303 – to monitor a subset of participants and check the long-term durability of the antibody response following a single dose of the chikungunya vaccine.

In August 2022, Valneva started a rolling biologics license application (BLA) submission with the FDA, seeking approval for its single-shot chikungunya vaccine, VLA1553, in adults. The company remains on track to complete rolling submission for the BLA by 2022-end.

If approved, VLA1553 will also be the first vaccine for chikungunya and Valneva will be eligible for a priority review voucher. VLA1553 was granted Breakthrough Designation therapy and Fast Track designations by the FDA.

Apart from VLA1553, Valneva is also developing a vaccine for Lyme disease VLA15.

Last week, the company reported six-month antibody persistence data after completing a three-dose or a two-dose vaccination schedule of VLA15, in adults and children aged five through 65 years. Shares of VALN jumped on this news.

Data from the phase II VLA15-221 study showed that the antibody levels generated by VLA15 in both vaccination schedules remained above baseline.

Please note that Valneva is developing VLA15 in collaboration with drug giant, Pfizer PFE.

The company entered into a collaboration with Pfizer in 2020 to co-develop VLA15 for Lyme disease.

Following the initiation of the phase III study for VLA15 in Lyme disease this year, PFE made a $25 million payment to Valneva as a milestone payment.
