9 Case presentation KKT Male, born 1997, previously healthy April 2012: Sternal tumor, erroneously diagnosed as LCH, treated with Vinblastine and steroids April 2013: Progressive lesion in the sternum, rebiopsied, now chl, stage IIBEX Treatment according to protocol Euronet-PHL-C1 2 OEPA, interim PET-CT positive, 4 COPDAC, progression prior to planned RT IEP and ABVD, progression 3 courses of brentuximab vedotin, no change 2 courses of IGEV, no change 2 courses of DHAP, radiological partial remission but still PET-CT positive High dose treatment (BEAM), ASCT and involved field RT to 30(36) Gy LCH; Langerhans cell histiocytosis, OEPA; Vincristine, Etoposide, Prednisolone, Doxorubicin, COPDAC; Cyclophosphamide, Vincristine, Prednisolone, Dacarbazine, IEP; Ifosfamide, Etoposide, Prednisolone, ABVD; Doxorubicin, Bleomycin, Vinblastine, Dacarbazine, IGEV; Ifosfamide, Gemcitabine, Vinorelbine, DHAP; Dexamethasone, AraC, Cisplatin, BEAM; BCNU, Etoposide, AraC, Melphalan, ASCT; autologous stem cell transplantation; RT; Radiotherapy, chl; Classical Hodgkin lymphoma

10 Case presentation KKT February 2015: Progression in the mediastinum, sternum and lungs Rebiopised with findings of chl (CD30 positive) 6 courses of brentuximab vedotin and bendamustin, radiological partial remission but PET-CT positive disease. Not accepted for allogeneic Tx, matched unrelated donor identified. chl; Classical Hodgkin lymphoma, Tx; Transplantation

11 Case presentation KKT July 2015: Accepted for Keynote 87 (MK ). At start: Palpable tumor upper stenal end, shortness of breath when exercising. Near normal blood test, DLCO 58% of predicted value. 4 courses of pembrolizumab iv, 200 mg, q3w Uneventful, no relevant toxicity. Response assessment at week 12. DLCO; diffusing capacity or transfer factor of the lung for carbon monoxide

12 Response assessment week 12 KKT Baseline Week 12

13 Case presentation KKT 3 further courses of pembrolizumab Uneventful, no serious adverse effects, no signs of IRP, weight loss of 10 %. Scheduled response assessment at week 20

14 Response assessment week 20 KKT Week 12 Week 20

15 Allogeneic transplant after PD-1 inhibition? CONTRA PRO increased toxicity after PD-1 inhibition? lasting remissions after PD-1 inhibition? no biomaker to predict long term outcome proven curative option best results for patients in remission no salvage option in case of progression intensified GVHD prophylaxis? GVHD; Graft versus host disease Armand et al, 2015
