Proteasome inhibition enhances myeloma oncolytic reovirus therapy by suppressing monocytic anti-viral immune responses
Bibliographic record
Abstract
Abstract Reovirus is an oncolytic virus with natural tropism for cancer cells. We previously showed that reovirus intravenous administration in myeloma patients was safe, but disease control associated with viral replication in the cancer cells was not observed. Here we show that ex vivo proteasome inhibitors (PIs) potentiate reovirus replication in circulating classical monocytes, increasing viral delivery to myeloma cells. We found that the anti-viral signals in monocytes primarily rely on the NF-kB activation and that this effect is impaired by the addition of PIs. Conversely, PIs improved reovirus-induced monocyte and T cell activation against cancer cells. Based on these preclinical data, we conducted a phase 1b trial of the reovirus Pelareorep together with the PI carfilzomib in 13 heavily pretreated bortezomib-resistant MM patients. Objective responses associated with reovirus active replication in MM cells, T cell activation and monocytic expansion were noted in 70% of patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
