Icosavax Reviews Constructive Sturdiness Information for VLP Vaccine Candidate IVX-121 In opposition to RSV at Six-Month Timepoint – Bio Tech Winners

Final Up to date on December 13, 2022 by GlobeNewsWire

– In new information from Section 1/1b research, IVX-121 confirmed sustained immunologic response at six months; geometric imply titers (GMT) in opposition to RSV-A via day 180 persisting at 64-98% of the GMTs at day 28 in older adults –

– First scientific proof of potential differentiation on sturdiness with firm’s VLP platform expertise –

– IVX-121 continues to be typically effectively tolerated with no security considerations noticed on this six-month observe up –

– IVX-A12 (a bivalent of IVX-121 for RSV and IVX-241 for hMPV) progressing in Section 1, and the one clinical-stage candidate concentrating on these two main causes of pneumonia in a single mixture –

SEATTLE, Dec. 13, 2022 (GLOBE NEWSWIRE) — Icosavax, Inc. (Nasdaq: ICVX), a biopharmaceutical firm leveraging its revolutionary virus-like particle (VLP) platform expertise to develop vaccines in opposition to infectious illnesses, with an preliminary concentrate on life-threatening respiratory illnesses and a imaginative and prescient of making pan-respiratory vaccines for older adults, at present offered a six-month immunogenicity replace from its Section 1/1b trial of IVX-121 in opposition to Respiratory Syncytial Virus (RSV). These new information exhibit a sustained neutralizing antibody (nAb) response in opposition to RSV, lasting for not less than six months after a single administration of IVX-121.

“We’re delighted to share the six-month immunogenicity information from our Section 1/1b trial of IVX-121. The potential for long-lasting immune responses was a part of our founding speculation and preclinical rationale for creating mixture VLP vaccines, so it’s thrilling to see this supportive preliminary scientific information on sturdiness from our platform,” mentioned Adam Simpson, Chief Government Officer of Icosavax. “We proceed to consider that there’s a want for higher vaccines, particularly the potential for mixture respiratory vaccines with longer-lasting safety and low reactogenicity.”

IVX-121 (RSV) Section 1/1b six-month immunogenicity replace

IVX-121 continued to be typically well-tolerated with no security considerations noticed on this six-month observe up and no vaccine associated severe opposed occasions (SAEs).

Information proven and described beneath illustrate the continued neutralizing antibody responses to a single administration of IVX-121 at three dosage ranges (25, 75, 250 ug), within the teams with out adjuvant. Samples had been taken at baseline, day 28, and day 180, with neutralizing antibodies measured in worldwide items (IU/mL) utilizing the WHO worldwide reference customary.

Determine 1 – RSV-A nAb, GMT expressed in IU/mL

In these day 180 immunogenicity information throughout IVX-121 unadjuvanted dosage teams, the sample of sturdiness was comparable in each younger and older grownup teams.

Within the older grownup portion of this research (Section 1b), GMTs for RSV-A nAbs that had been beforehand reported at as much as 7,561 IU/mL at day 28 had been noticed to persist at as much as 6,184 IU/mL via day 180. GMTs for RSV-A at day 180 had been maintained inside a spread of 64-98% relative to the beforehand reported GMTs at day 28. GMTs for RSV-B confirmed larger variability however had been maintained above baseline via day 180.

Icosavax plans to supply a 12-month immunogenicity replace from an extension of this Section 1b trial in mid-2023. The corporate additionally intends to current extra information from its Section 1/1b scientific trial of IVX-121 at a future medical assembly.
