    Abstract: 4029 Background: Advanced esophageal squamous cell cancer (ESCC) is frequently diagnosed in elderly patients (pts) with additional comorbidities. Limited treatment options are available. We report the safety interim analysis of a phase II clinical trial evaluating nivolumab and ipilimumab as second-line therapy for advanced ESCC in elderly pts. Methods: RAMONA is a multicenter open-label phase II trial assessing nivolumab/ipilimumab combination therapy in elderly pts (≥65 years). The geriatric status of the pts was assessed using the G8 screening tool and the Deficit Accumulation Frailty Index (DAFI). After a run-in phase of 3 cycles nivolumab (240mg Q2W), cohort assignment was based on a safety assessment. Pts with toxicities grade ≤2 were considered eligible for escalation to nivolumab (240mg Q2W)/ipilimumab (1mg/kg Q6W) combination therapy (cohort B). Other pts remained on nivolumab monotherapy (cohort A). Primary endpoint is overall survival (OS). Key secondary endpoint is time to Quality of Life deterioration defined as a loss of ≥ 10 points in the EORTC QLQ-C30 compared to baseline. Adverse events were assessed according to NCI-CTCAE version 4.03. Results: From February 2018 until February 2020, 69 pts entered the study. 61 pts were eligible for safety interim analysis. Median age of the pts was 71.9 yrs (± 5.4), median KPS score was 80% (50-100%). In 73.8% of the pts, metastases were detected at the time of study inclusion. Most pts received the IO therapy in ≥ 2 nd line (91.8%). The mean G8-score at screening was 11.9 points (46 pts ≤ 14 points, 75.4%) (mean DAFI: 0.19). Based on safety assessment, 42 pts were escalated to nivolumab/ipilimumab, while 9 pts remained on nivolumab monotherapy. 10 pts were not allocated at the time of analysis. Median numbers of cumulative doses were 3.0 [1.0 - 3.0] for the run-in phase (nivolumab), 6.0 [1.0 – 48.0] for nivolumab therapy (cohort A/B) and 2.5 [1.0 – 16.0] for ipilimumab (cohort B). Median treatment duration was 144.5 days (56-781 days) in cohort A and 231 days (85-484 days) in cohort B. Frailty indices remained stable after 3 cycles of nivolumab with limited toxicity at the time of the safety assessment. Drug-related treatment emergent adverse events (AEs) were observed in 42 pts (68.9%); 29/42 in cohort A, 8/9 in cohort B, and 5/10 pts not allocated at the time of analysis. Grade ≥3 AEs were detected in 9 pts of 42 in cohort A and 4 of 9 pts in cohort B. Drug-related treatment emergent serious adverse events (SAEs) were detected in 12 pts (19.7%); 8/42 in cohort A, 2/9 pts in cohort B, and 2/10 pts not yet allocated. Conclusions: Combined nivolumab/ipilimumab is a safe and feasible second-line therapy for elderly pts with advanced ESCC. Most pts could be escalated to nivolumab/ipilimumab. Treatment duration was exceptional long for a subset of pts. Clinical trial information: NCT03416244.

    Nivolumab plus ipilimumab in second-line combination therapy for older patients with esophageal squamous cell cancer (AIO-STO-0117 trial).
    American Society of Clinical Oncology (ASCO) ; 2022

    Abstract: 303 Background: Overall survival of patients with advanced and refractory esophageal squamous cell carcinoma (ESCC) is poor. Most patients are 65 years or older, present with advanced and metastatic disease and suffer from extensive co-morbidity and decreased functionality. While approved therapies beyond first-line therapy have not been available for decades, just recently treatment with PD-1 antibodies has shown to improve progression-free and overall survival in this patient cohort. Thus, we assessed the combination of nivolumab and ipilimumab in this vulnerable and older patient population. Methods: In this multi-center, open-label phase II trial older patients with ESCC with progression or recurrence of disease following first-line therapy were treated with nivolumab and ipilimumab. Patients had to pass a brief geriatric assessment using the G8 screening tool in combination with the Deficit Accumulation Frailty Index (DAFI). A safety run–in phase was initiated with nivolumab (240mg fixed dose Q2W). Following a safety assessment, patients then went on to receive the combination therapy of nivolumab/ipilimumab (nivolumab 240 mg fixed dose Q2W; ipilimumab 1 mg/kg Q6W), in case safety was critical patients were allowed to continue with nivolumab monotherapy. The primary outcome was overall survival. Progression-free survival, quality of life and adverse events were also assessed. Results: In total 66 evaluable patients (16 female, 50 male) with ESCC were enrolled in this trial after successful geriatric assessment, median age was 70.5 years (range 55-84 years). 44 patients were treated with the combination therapy of nivolumab and ipilimumab, 22 patients with nivolumab only. The primary endpoint was met with a median OS of 7.2 months (95% CI, 5.7 to 12.4 months) (p 〈 0.006; versus historical control treated with standard chemotherapy). Median PFS was 2.7 months (95% CI, 2.5 to 2.9 months). ORR was 18.2% (95% CI, 9.8 to 29.6), all cases were partial responses. Grade 3 or more treatment related adverse events were observed in ̃25% of patients. Conclusions: The combination therapy of nivolumab and ipilimumab demonstrates improved overall survival and sustained confirmed responses in the second line therapy of older European patients with ESCC. Geriatric assessment is feasible in the setting of a prospective immune therapy trial. Overall, the RAMONA trial confirmed efficacy and safety of combination checkpoint inhibitor therapy in G8 prescreened older patients with ESCC in Europe beyond first line therapy. Clinical trial information: NCT03416244.

    Abstract: In patients with newly diagnosed glioblastoma that harbors a nonmethylated O 6 -methylguanine–DNA methyltransferase promotor, standard temozolomide (TMZ) has, at best, limited efficacy. The GLARIUS trial thus explored bevacizumab plus irinotecan (BEV+IRI) as an alternative to TMZ. Patients and Methods In this phase II, unblinded trial 182 patients in 22 centers were randomly assigned 2:1 to BEV (10 mg/kg every 2 weeks) during radiotherapy (RT) followed by maintenance BEV (10 mg/kg every 2 weeks) plus IRI(125 mg/m 2 every 2 weeks) or to daily TMZ (75 mg/m 2 ) during RT followed by six courses of TMZ (150-200 mg/m 2 /d for 5 days every 4 weeks). The primary end point was the progression-free survival rate after 6 months (PFS-6). Results In the modified intention-to-treat (ITT) population, PFS-6 was increased from 42.6% with TMZ (95% CI, 29.4% to 55.8%) to 79.3% with BEV+IRI (95% CI, 71.9% to 86.7%; P 〈 .001). PFS was prolonged from a median of 5.99 months (95% CI, 2.7 to 7.3 months) to 9.7 months (95% CI, 8.7 to 10.8 months; P 〈 .001). At progression, crossover BEV therapy was given to 81.8% of all patients who received any sort of second-line therapy in the TMZ arm. Overall survival (OS) was not different in the two arms: the median OS was 16.6 months (95% CI, 15.4 to 18.4 months) with BEV+IRI and was 17.5 months (95% CI, 15.1 to 20.5 months) with TMZ. The time course of quality of life (QOL) in six selected domains of the European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire (QLQ) –C30 and QLQ-BN20 (which included cognitive functioning), of the Karnofsky performance score, and of the Mini Mental State Examination score was not different between the treatment arms. Conclusion BEV+IRI resulted in a superior PFS-6 rate and median PFS compared with TMZ. However, BEV+IRI did not improve OS, potentially because of the high crossover rate. BEV+IRI did not alter QOL compared with TMZ.

    Abstract: To evaluate the role of a second allogeneic hematopoietic stem-cell transplantation (HSCT2) given for relapsed acute leukemia (AL) after related or unrelated first hematopoietic stem-cell transplantation (HSCT1) and to analyze the role of donor change for HSCT2 in both settings. Patients and Methods We performed a retrospective registry study on 179 HSCT2s given for relapse after HSCT1 from matched related donors (n = 75) or unrelated donors (n = 104), using identical or alternative donors for HSCT2. Separate analyses were performed according to donor at HSCT1. Results Independent of donor, 74% of patients achieved complete remission after HSCT2, and half of these patients experienced relapse again. Overall survival (OS) at 2 years was 25% ± 4% (39% ± 7% after related HSCT2; 19% ± 4% after unrelated HSCT2). Long-term survivors were observed even after two unrelated HSCT2s. Multivariate analysis for OS from HSCT2 confirmed established risk factors (remission duration after HSCT1: hazard ratio [HR], 2.37; 95% CI, 1.61 to 3.46; P 〈 .001; stage at HSCT2: HR, 0.53; 95% CI, 0.34 to 0.83; P = .006). Outcome of HSCT2 was better after related HSCT1 than after unrelated HSCT1 (2-year OS: 37% ± 6% v 16% ± 4%, respectively; HR, 0.68; 95% CI, 0.47 to 0.98; P = .042, multivariate Cox regression). After both related and unrelated HSCT1, selecting a new donor for HSCT2 did not result in a relevant improvement in OS compared with HSCT2 from the original donor; however, donor change was not detrimental either. Conclusion After relapse from allogeneic HSCT1, HSCT2 can induce 2-year OS in approximately 25% of patients. Unrelated HSCT2 is feasible after related and unrelated HSCT1. Donor change for HSCT2 is a valid option. However, a clear advantage in terms of OS could not be demonstrated.

    Abstract: 9519 Background: Simultaneous inhibition of MEK and CDK4/6 may suppress MAPK pathway activation and cell-cycle checkpoint dysregulation in NRAS-mutant melanoma, resulting in enhanced antitumor activity. Phase 1b data are reported. Methods: The phase 1b primary objective was to determine maximum tolerated dose (MTD)/RP2D. A 28-d cycle of oral ribociclib (RIBO) once daily (QD) for 21 d + oral binimetinib (BINI) twice daily (BID) for 28 d, and a 21-d cycle of RIBO QD + BINI BID, both for 14 d per cycle, were evaluated. Secondary objectives were to evaluate efficacy, safety and pharmacodynamics. Results: Based on dose escalation (van Herpen, ESMO 2015), MTD was 600mg RIBO/45mg BINI for the 21-d and 200/45 for the 28-d regimens. Due to promising activity, the 28-d cycle was selected as RP2D(unconfirmed partial response [PR] with limited follow-up occurred in 35% of pts). This finding was supported by comparable and manageable safety and the Bayesian logistic regression model.As of Jan 2017, the RP2D was received by 16 pts in phase 1b (ECOG PS 0/1/2, 63%/31%/6%; elevated lactate dehydrogenase, 44%; stage IVM1c disease, 50%; prior ipilimumab [ipi] , 44%; prior anti–programmed death [PD]-1/PD-L1, 31%). Median (range) exposure was 4 (0–13) mo. Common adverse events (AEs) were increased blood creatine phosphokinase, elevated AST, peripheral edema, acneiform dermatitis, diarrhea and fatigue. Common grade 3/4 AEs were elevated AST and ALT (19%/6%), nausea (19%/0%), rash (19%/0%), vomiting (6%/6%) and neutropenia (12%/0%). Confirmed PR (cPR) occurred in 4 pts (25%; time to response, 48–168 d), stable disease in 7 pts (44%), disease progression in 3 pts (19%); 2 pts (12%) were not evaluable. Among cPR pts, 3 had prior ipi and/or anti–PD-1/PD-L1. Median progression-free survival (mPFS) was 6.7 (95% CI, 3.5–9.2) mo. Sequence analysis of synchronous non- RAS genetic alterations will be presented. Conclusions: Combined RIBO/BINI at the s elected RP2D had a manageable safety profile and favorable efficacy (based on mPFS) for NRAS-mutant melanoma in phase 1b. Based on these promising data, the phase 2 expansion is underway to assess antitumor activity at the RP2D. Clinical trial information: NCT01781572.

    Abstract: 4004 Background: The MAGIC trial established perioperative (periop) epirubicin, cisplatin, and 5-FU (ECF) as a standard treatment for patients (pts) with operable esophagogastric cancer, but survival continues to remain poor. FLOT4 (NCT01216644) is a multicenter, randomized, investigator-initiated, phase 3 trial. It compares the docetaxel-based triplet FLOT with the anthracycline-based triplet ECF/ECX as a periop treatment for pts with resectable gastric or GEJ adenocarcinoma. Methods: Eligible pts of stage ≥cT2 and/or cN+ were randomized to either 3 preoperative and 3 post-operative 3-week cycles of ECF/ECX (epirubicin 50 mg/m2, cisplatin 60 mg/m², both d1, and 5-FU 200 mg/m² as continuous infusion or capecitabine 1250 mg/m2 orally d1-21) or 4 pre-operative and 4 post-operative 2-week cycles of FLOT (docetaxel 50 mg/m2, oxaliplatin 85 mg/m², leucovorin 200 mg/m², and 5-FU 2600 mg/m² as 24-hour infusion, all d1). The primary endpoint was overall survival (OS; 80% power; HR of 0.76; 2-sided log-rank test at 5% type I error). Results: Between Aug 2010 and Feb 2015, 716 pts (360 ECF/ECX; 356 FLOT) were randomly allocated. Baseline characteristics were similar between arms (overall, male 74%; median age 62; cT3/T4 81%; cN+ 80%; GEJ 56%). 91% and 37% of pts with ECF/ECX and 90% and 50% with FLOT completed planned pre-operative and post-operative cycles, respectively. Median follow-up was 43 mon. 369 pts died (203 ECF/ECX; 166 FLOT). FLOT improved OS (mOS, 35 mon with ECX/ECF vs. 50 mon with FLOT; HR 0.77 [0.63 - 0.94]; p = 0.012). 3y OS rate was 48% with ECF/ECX and 57% with FLOT. FLOT also improved PFS (mPFS, 18 mon with ECX/ECF vs. 30 mon with FLOT; HR 0.75 [0.62 - 0.91] ; p = 0.004). Periop complications were 50% with ECF/ECX and 51% with FLOT. 30- and 90-day mortality was 3% and 8% with ECF/ECX and 2% and 5% with FLOT. There was more G3/4 nausea and vomiting with ECF/ECX and more G3/4 neutropenia with FLOT. Conclusion: Periop FLOT improved outcome in patients with resectable gastric and GEJ cancer compared to periop ECF/ECX. Clinical trial information: NCT01216644.

    Abstract: 12049 Background: GA is recommended to guide therapy for elderly cancer pts. To assess whether GA results influence the recommended treatment and the inter-oncologist variability of treatment recommendations, we conducted a case-vignette-based study in medical oncologists (MOs). Methods: MOs were asked to give medical treatment recommendations for GI cancer pts in three steps: (1) based on tumor findings alone to simulate the guideline recommendation for a “50-year-old standard patient (pat.) without comorbidities”, (2) for the same tumor situation in an elderly pat. according to the medical history, comorbidities, lab values and a short video simulating the clinical consultation situation and (3) after in addition the results of a full GA were disclosed (Barthel index, Cumulative Illness Rating Scale, G8, Geriatric Depression Scale, Mini Mental Status Examination, Mini-Nutritional-Assessment [MNA], Time Get Up and Go, EORTC-QLQ30 and stair climb test - each with short interpretation aid). Each MO voted for 2-4 randomly allocated pts out of a pool of 10 pts with mean age 78.5 years. A slider (like a visual analogue scale) was used to express the grade of recommendation for several treatment options per patient. The means and variances for each treatment option were calculated and compared for analysis. Results: Seventy German MOs had given 164 treatment recommendations that were substantially different for elderly compared to younger pts. The recommendations had a significantly higher variance for elderly pts than for the “standard” pts (p 〈 0.0001) indicating a lower inter-oncologist agreement regarding the treatment recommendations in elderly pts. MOs with 〉 6 years working experience as specialist had no lower variance in their recommendations. There was a non-significant trend towards a lower variance if the MOs were based at outpatient units of hospitals (compared to MOs working with in-patients or as private oncologists) and for MOs working at larger hospitals ( 〉 800 beds) compared to those based at smaller ones. The knowledge on the full GA results had marginal influence on the treatment recommendations itself or its variance, only (p = 0.92). In the survey, the geriatric tools were rated more than two times higher as being meaningful (53%) and useful (49%) than they were used in clinical practice (19%). The most used tool in the routine care for geriatric pts was the MNA (30%). Conclusions: There is a large variability regarding the "optimal" treatment in geriatric pts without meaningful improvement with larger working experience. Although the recommended therapeutic regime varied in elderly pts and the MOs rated the GA results as “useful”, the GA results did not influence the individual recommendations or its variance, and GA is rarely used in daily practice indicating that more research on an effective implementation into the clinical practice is needed.

    Abstract: TPS2658 Background: Growth and differentiation factor 15 (GDF-15) is a TGF-β superfamily member physiologically expressed mainly in placenta and linked to feto-maternal tolerance. Under pathophysiologic conditions, prevention of excessive immune cell infiltration during tissue damage and cachexia induction have been ascribed to GDF-15. A recent study [Haake et al. AACR2020; Abstract #5597] elucidated a mechanism by which GDF-15 inhibits LFA-1 activation on CD8+ T cells, thus interfering with effector T cell recruitment to tissues. Importantly, several cancer entities secrete high levels of GDF-15, correlating with poor prognosis and reduced overall survival [reviewed in Front Immunol 2020 May 19;11:951] . To block this effect the GDF-15 neutralizing antibody CTL-002 was generated. In preclinical models CTL-002 demonstrated potent effector T cell shifting into tumor tissue by neutralizing GDF-15. Methods: This is a phase 1, first-in-human (FIH), two-part, open-label clinical trial of intravenous (IV) administration of CTL-002 given as monotherapy and in combination with an anti-PD-1 antibody in subjects with advanced-stage, relapsed/refractory solid tumors who relapsed post or were refractory to a prior anti-PD-1/PD-L1 therapy. Eligible subjects have exhausted all available approved standard treatments. Further key eligibility criteria include having received at least one prior anti-PD1/-PD-L1 treatment and having relapsed on or after it or having been refractory to it, and presenting with a biopsy-accessible tumor for serial biopsy taking. The trial is termed GDFATHER, for “GDF-15 Antibody-mediaTed Effector cell Relocation”. Main endpoints are safety of CTL-002 monotherapy and CTL-002 combination with an anti-PD-1 antibody, pharmacokinetics, pharmacodynamics (e.g. degree of GDF-15 neutralization achieved and change in immune-cell number and composition in the tumor tissue) as well as preliminary clinical efficacy (tumor mass reduction; anticachexia effect) In part A of the trial (dose escalation) up to 24 subjects will receive escalating doses of CTL-002 IV (0.3 – 20 mg/kg) in a „mono-followed-by-combination“-design with CTL-002 given as monotherapy and followed by combination with an anti-PD-1 checkpoint inhibitor. In part B (expansion) up to 5 cohorts with up to 25 subjects per cohort with defined tumor entities expected to be GDF-15 dependent will be treated to determine the recommended phase 2 dose (RP2D) and further evaluate safety and preliminary efficacy of CTL-002 monotherapy and the combination. The study was initiated in December 2020 and enrolled the first patient on Dec 09, 2020. Cohort 1 has been completed without DLT and enrollment for cohort 2 began in February 2021. Clinical trial information: NCT04725474.
