Brief Summary: Adenoid cystic carcinoma AdCC is a rare salivary gland malignant tumor that accounts for approximately 1-3 of all head and neck cancers AdCC is often charaterised by a long natural history with a propensity for indolent but relentless growth and dissemination Local recurrences and late distant metastases are common findings in about 35 of the patients and associated with a poor prognosis1 AdCC is among the most lethal salivary gland tumors2 with no proven therapy for metastatic disease Little is known about endogenous immune response directed against AdCC However in a relatively large series of 28 AdCC tumor the immune profiling has shown in most tumors high and frequent programmed death ligand 2 PD-L2 expression and PD-L1 was generally not expressed on tumor and infiltrating cells3

The Antibody Drug Conjugates ADCs are emerging as a novel therapeutic option in cancer treatment that looks promising for solid tumors An experimental CD205Ly75-directed ADC OBT076 induce potent cytotoxic and antitumor activity Recently the combination of immunohistochemistry IHC and tissue micro array TMA was performed in a series of 46 AdCC showing a unique profile with both frequent and high expression of CD205Ly75 much higher than for other solid tumors In a phase I study OBT076 demonstrated promising results for 3 patients with 2 partial responses and 1 complete response for a gastric cancer4 In this last patient analysis showed an increase in PD1 CD4 and CD8 cells suggesting that OBT076 activates the patients immune response against the tumor especially PD-1 targeted therapies4

Based on this rational and on the high level of expression of CD205Ly75 in AdCC the hypothesis tested in this study is that OBT076 could be a potential effective treatment for RM AdCC which is an orphan lethal disease The efficacy of OBT076 will be tested either alone or followed by an anti PD-1 inhibitor Balstilimab with the hypothesis that OBT076 will induce immune infiltrate that could restore sentivity to PD-1 targeting
