Personalized Cancer Vaccines

A Canadian company is building the path to personalized cancer vaccines, and the software that decides which targets are worth using.

Our Neoantigen Selection Platform, known as NSP, is how the company decides, for each patient, which of a tumor's mutations are worth turning into medicine.

Disrupting cancer therapy, one patient at a time.

The Problem

Personalized cancer vaccines show unmatched real clinical promise. Consistent, durable benefit across all patients is the unsolved part.

100%
of vaccinated patients developed a targeted immune response in Mount Sinai's PGV001 Phase 1 trial, which used a poly-ICLC adjuvant
44%
of the individual neoantigens administered in that same trial actually triggered a T-cell response
6/12
patients in that trial were still alive at five-year follow-up, an early but genuine signal of durability

Cancer remains one of the leading causes of death. Outside of surgery or immunotherapy, targeted therapy usually isn't curative. Several vaccine trials, across peptide, DNA and mRNA platforms, have already produced real, measurable results. The pattern across the field is that immune responses are common; making strong, durable results consistent from patient to patient is the harder problem. Rescue Bio exists to close that gap.

The Platform

NSP sits between "here is the tumor" and "here is what we manufacture"

The pipeline runs from sequencing through mutation calling, patient HLA typing, RNA-confirmed candidate generation, multi-dimensional scoring, and a capped, logged peptide pool, ending in human review before manufacturing.

Most pipelines stop at binding and expression

Candidates are usually scored almost entirely on how strongly a peptide binds and how much of it the tumor expresses. It is a real signal, but an incomplete one.

NSP adds a stemness-weighted layer

NSP weights candidates by whether the mutation is present in the tumor's stem-like, treatment-resistant cell population, not just the bulk tumor. It is a bet on preventing recurrence, not only shrinking the tumor today.

Lead Indications

Starting where the need is greatest

The company's initial focus is glioblastoma and pancreatic cancer, both essentially incurable once standard therapy is exhausted, with plans to expand into breast, renal and ovarian cancers.
