While immunotherapies carry great promise for improving outcomes for people with cancer, the ability of cancers to evade the immune system and develop resistance limits their benefits as monotherapies. BioEclipse Therapeutics is developing therapies that marry activated immune cells with oncolytic viruses. Together, they provide a synergistic effect that attacks cancers while providing protection against relapse and recurrence. We spoke to Pamela Contag, co-founder and CEO of BioEclipse, about the ability of cancers to return after treatment with immunotherapies, BioEclipse’s efforts to develop a multi-mechanistic immunotherapy to overcome that challenge, and why its approach may have broad application across a range of cancers.
