Abstract | PURPOSE: EXPERIMENTAL DESIGN: Nineteen dogs with naturally occurring DLBCL were entered into a prospective randomized placebo-controlled double-blinded trial of HSPPCs- hydroxylapatite plus chemotherapy versus chemotherapy alone. Endpoints included time to progression ( TTP), lymphoma-specific survival (LSS), and incidence of toxicoses. RESULTS: Median first TTP after randomization to the vaccine arm was 304 days versus 41 days for the control arm (P = 0.0004). There was also a statistically significant difference in duration of second remission between the two groups (P = 0.02). Median LSS was 505 days for the vaccinated dogs versus 159 days for the unvaccinated dogs (P = 0.0018). Six vaccinated dogs achieved molecular remission, as shown by clonal immunoglobulin H (IgH) rearrangement. Toxicoses were comparable between the two treatment arms. CONCLUSIONS: The results of this trial demonstrate that the autologous vaccine tested here is safe and efficacious in prolonging TTP and LSS in dogs with DLBCL when used in combination with dose-intense chemotherapy. On the basis of these results, additional evaluation of this novel therapeutic strategy is warranted in human DLBCL.
