Interferon-? (IFN?) has been prescribed to effectively treat multiple myeloma
(MM) and other malignancies for decades. Its use has waned in recent years,
however, due to significant toxicity and a narrow therapeutic index (TI). We
sought to improve IFN?'s TI by, first, attaching it to an anti-CD38 antibody,
thereby directly targeting it to MM cells, and, second, by introducing an
attenuating mutation into the IFN? portion of the fusion protein rendering it
relatively inactive on normal, CD38 negative cells. This
anti-CD38-IFN?(attenuated) immunocytokine, or CD38-Attenukine?, exhibits
10,000-fold increased specificity for CD38 positive cells in vitro compared to
native IFN? and, significantly, is ~6,000-fold less toxic to normal bone marrow
cells in vitro than native IFN?. Moreover, the attenuating mutation significantly
decreases IFN? biomarker activity in cynomolgus macaques indicating that this
approach may yield a better safety profile in humans than native IFN? or a
non-attenuated IFN? immunocytokine. In human xenograft MM tumor models,
anti-CD38-IFN?(attenuated) exerts potent anti-tumor activity in mice, inducing
complete tumor regression in most cases. Furthermore, anti-CD38-IFN?(attenuated)
is more efficacious than standard MM treatments (lenalidomide, bortezomib,
dexamethasone) and exhibits strong synergy with lenalidomide and with bortezomib
in xenograft models. Our findings suggest that tumor-targeted attenuated
cytokines such as IFN? can promote robust tumor killing while minimizing systemic
toxicity.
