In oropharyngeal squamous cell carcinoma (OPC), high CD8 tumor-infiltrating lymphocyte (CD8 TIL) density confers improved prognosis. We compared neoadjuvant durvalumab (PD-L1 inhibitor) with durvalumab + tremelimumab (CTLA-4 inhibitor) in terms of impact on CD8 TIL density, safety, and efficacy in patients with OPC. Patients with newly diagnosed stage II-IVA OPC or locoregionally recurrent OPC amenable to resection were included. Patients were randomized to two cycles of durvalumab or durvalumab + tremelimumab before surgery. The primary endpoint was change between baseline and resection specimen in CD8 TIL density between arms. Secondary endpoints included safety, response rate per RECIST, major pathologic response (MPR; ≤10% viable tumor cells) rate, and patient-reported outcomes. Of 28 eligible patients (14/arm), 20 (71%) had newly diagnosed OPC, and 24 (86%) were p16-positive. The posttreatment to pretreatment median CD8 TIL density ratio was 1.31 for durvalumab and 1.15 for combination treatment ( = 0.97; 95% CI: -1.07-2.28). In each group, 6 patients (43%, 95% CI: 17.66-71.14) had a response. Eight patients (29%) had a MPR at the primary tumor and/or nodal metastases. Neither baseline CD8 TIL density nor PD-L1 expression level correlated with overall response, but a trend toward greater CD8 TIL change in patients with a MPR was seen ( = 0.059; 95% CI: -0.33-3.46). Four patients (14%) had grade ≥3 adverse events. At median follow-up time of 15.79 months, all patients were alive, and one had an additional recurrence. Durvalumab + tremelimumab did not increase CD8 TIL density more than durvalumab alone did. The observed safety and activity support further investigation of neoadjuvant checkpoint inhibitor for OPC.
