An­oth­er TIG­IT up­date from Ar­cus leaves an­a­lysts read­ing the tea leaves — and the big re­veal is fi­nal­ly near

Once again, any­one who’s look­ing for pos­i­tive sig­nals in Ar­cus’ lat­est slice of TIG­IT da­ta will have to take the biotech’s word for it.

Ar­cus opened its Q1 re­sults with an up­date about its third in­ter­im analy­sis for the ARC-7 study, a Phase II tri­al com­par­ing three dif­fer­ent reg­i­mens: a PD-1 monother­a­py, a TIG­IT plus PD-1 com­bo, as well as a triplet con­tain­ing PD-1, TIG­IT and an A2aR/A2bR an­tag­o­nist. With­out spelling out the num­bers, ex­ecs said “both an­ti-TIG­IT dom­vanal­imab-con­tain­ing arms con­tin­ued to show mean­ing­ful dif­fer­en­ti­a­tion com­pared to the an­ti-PD1 an­ti­body zim­bere­limab alone when giv­en as a treat­ment for first-line metasta­t­ic non-small cell lung can­cer (NSCLC).”
