OPTIM: a randomized phase II trial of nivolumab followed by nivolumab-ipilimumab or docetaxel at progression in recurrent/metastatic squamous cell carcinoma of the head and neck (OPTIM; AIO-KHT-0117).
Trial report in British journal of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTreatment options after PD-1 inhibition for recurrent/metastatic squamous cell carcinoma of the head and neck (R/M-SCCHN) remain limited. We investigated whether staggered immune checkpoint inhibition could improve outcomes compared with docetaxel in nivolumab-refractory disease.
methodsIn this randomized phase II trial, adults with platinum-refractory R/M-SCCHN received nivolumab and were randomized at progression to nivolumab 3 mg/kg every 2 weeks plus ipilimumab 1 mg/kg every 6 weeks (NIVO-IPI) or docetaxel 75 mg/m² every 3 weeks (DOCE) until progression or intolerance. The primary endpoint was objective response rate (ORR) per RECIST 1.1; progression-free survival (PFS), overall survival (OS), and safety were secondary endpoints. PD-L1 expression was assessed in all patients.
resultsAmong 14 patients in the NIVO-IPI arm and 17 in the DOCE arm, ORR was 0% versus 17.6%, median PFS was 1.97 versus 3.66 months (P = 0.036), and median OS was 3.97 versus 11.9 months (P = 0.356), respectively. Twelve-month OS rates were 28.6% and 44.6%. Outcomes were similar irrespective of PD-L1 status. Treatment-emergent adverse events occurred in 84.6% versus 81.3% of patients, with grade ≥3 events in 38.5% and 68.8%.
conclusionsNIVO-IPI did not improve efficacy over docetaxel and showed numerically inferior survival, whereas docetaxel was associated with greater toxicity. CLINICAL
