BACKGROUND: Preclinical studies suggest that combining nivolumab, a programmed death-1 (PD-1) immune checkpoint inhibitor, with pomalidomide/dexamethasone (Pd) with or without elotuzumab, an antisignaling lymphocytic activation molecule F7 monoclonal antibody, may improve multiple myeloma (MM) treatment efficacy. PATIENTS AND METHODS: The phase 3 CheckMate 602 study (NCT02726581) assessed the efficacy and safety of nivolumab plus pomalidomide/dexamethasone (NPd) and NPd plus elotuzumab (NE-Pd). Eligible patients (aged ≥ 18 years) had measurable MM after ≥ 2 prior lines of therapy, that included an immunomodulatory drug (IMiD) and proteasome inhibitor (PI), each for ≥ 2 consecutive cycles, alone or combined, and were refractory to their last line of therapy. Patients were randomized 3:3:1 to receive NPd, Pd, or NE-Pd. The primary endpoint was progression-free survival (PFS); overall response rate (ORR) was a key secondary endpoint. RESULTS: At a median follow-up of 16.8 months, PFS was similar between treatment arms (Pd, 7.3 months [95% CI, 6.5-8.4]; NPd, 8.4 months [95% CI, 5.8-12.1]; NE-Pd, 6.3 months [95% CI, 2.4-11.1]). ORR was similar in the Pd (55%), NPd (48%), and NE-Pd (42%) arms. Nivolumab-containing arms were associated with a less favorable safety profile versus Pd, including a higher rate of thrombocytopenia (NPd, 25.0%; NE-Pd, 16.7%; Pd, 15.7%), any-grade immune-mediated adverse events (NPd, 13.9%; NE-Pd, 16.7%; Pd, 2.9%), and adverse events leading to discontinuation (NPd, 25.0%; NE-Pd, 33.3%; Pd, 18.6%). No new safety signals were identified. CONCLUSION: CheckMate 602 did not demonstrate clinical benefit of nivolumab (+/- elotuzumab) plus Pd versus Pd for patients with relapsed/refractory MM (RRMM).

INTRODUCTION: This double-blind, parallel-group, active-controlled phase III trial (NCT02260804) assessed CT-P10 and rituximab safety and efficacy in patients with previously untreated low-tumor-burden follicular lymphoma (LTBFL), including after a single switch from rituximab to CT-P10. PATIENTS AND METHODS: LTBFL patients were randomized (1:1) to receive CT-P10 or rituximab (375 mg/m2 intravenously; day 1 of 4 7-day cycles). Patients achieving disease control entered a 2-year maintenance period. CT-P10 or rituximab were administered every 8 weeks (6 cycles) in year 1; all patients could receive CT-P10 (every 8 weeks; 6 cycles) in year 2. Secondary endpoints (reported here) were overall response rate (ORR) during the study period, progression-free survival (PFS), time to progression (TTP), and overall survival (OS). Safety and immunogenicity were evaluated. RESULTS: Between November 9, 2015 and January 4, 2018, 258 patients were randomized (130 for CT-P10; 128 for rituximab). ORR was similar between groups over the study period (CT-P10: 88%; rituximab: 87%). After 29.2 months' median follow-up, median PFS, TTP, and OS were not estimable; 24-month Kaplan-Meier estimates suggested similarity between groups. Overall, 114 (CT-P10: 88%), and 104 (rituximab: 81%) patients experienced treatment-emergent adverse events. The single switch was well tolerated. CONCLUSION: These updated data support therapeutic similarity of CT-P10 and rituximab and support the use of CT-P10 monotherapy for previously untreated LTBFL.

BACKGROUND: Studies in patients with rheumatoid arthritis and advanced follicular lymphoma have shown that CT-P10, a rituximab biosimilar, has equivalent or non-inferior efficacy and pharmacokinetics to rituximab. We aimed to assess the therapeutic equivalence of single-agent CT-P10 and rituximab in patients with newly diagnosed low-tumour burden follicular lymphoma. METHODS: In this ongoing, randomised, double-blind, parallel-group, active-controlled, phase 3 trial, adult patients (≥18 years) with stage II-IV low-tumour-burden follicular lymphoma were randomly assigned (1:1) using an interactive web or voice response system stratified by region, stage, and age to CT-P10 or US-sourced rituximab. Patients received CT-P10 or rituximab (375 mg/m2 intravenous) on day 1 of four 7-day cycles (induction period). Patients who had disease control after the induction period continued to a maintenance period of CT-P10 or rituximab administered every 8 weeks for six cycles and, if completed, a second year of maintenance therapy of additional CT-P10 (every 8 weeks for six cycles) was offered. The study was partially unmasked after database lock (Feb 23, 2018) for all data up to 7 months (before cycle 3 of the maintenance period). The primary endpoint was the proportion of patients who achieved an overall response by 7 months in the intention-to-treat population. Efficacy equivalence was shown if the two-sided 90% CIs for the treatment difference in the proportion of responders between CT-P10 and rituximab was within the equivalence margin of 17%. This trial is registered with ClinicalTrials.gov, number NCT02260804. FINDINGS: Between Nov 9, 2015, and Jan 4, 2018, 402 patients were assessed for eligibility, of whom 258 were randomly assigned: 130 to CT-P10 and 128 to rituximab. 108 (83%) of 130 patients assigned to CT-P10 and 104 (81%) of 128 assigned to rituximab achieved an overall response by month 7 (treatment difference estimate 1·8%; 90% CI -6·43 to 10·20). Therapeutic equivalence was shown (90% CIs were within the prespecified margin of 17%). The most common grade 3 or 4 treatment-emergent adverse events were decreased neutrophil count (two grade 3 in the CT-P10 group) and neutropenia (one in each group); all other grade 3 or 4 treatment-emergent adverse events occurred in one patient each. Six (5%) of 130 patients who received CT-P10 and three (2%) of 128 who received rituximab experienced at least one treatment-emergent serious adverse event. INTERPRETATION: CT-P10 was equivalent to rituximab in terms of efficacy and was well tolerated. CT-P10 monotherapy is suggested as a new therapeutic option for patients with low-tumour-burden follicular lymphoma. FUNDING: Celltrion, Inc.

Ankylozující spondylitida (AS) nebo také Bechtěrevova či Marieho-Strümpellova nemoc je chronické zánětlivé autoimunitní onemocnění postihující preferenčně páteř ve formě sakroileitidy a spondylitidy [1,2]. Díky získané fragilitě skeletu je odpověď organismu na mechanickou zátěž oproti zdravé páteři výrazně odlišná, a proto jsou u nemocných s AS traumata páteře mnohem nebezpečnější. Na rozdíl od převážně elastických poranění u zdravé krční páteře [3] se u nemocných s AS tato elasticita ztrácí a páteř se poté chová jako tubulární kost [4,5]. Prostý RTG snímek je často nedostačující, neboť bývá obtížné tyto fraktury nalézt v terénu rozsáhlých kostních přestavbových změn typických pro AS [6,7,8]. Předkládáme kazuisti-ku cervikální spondylogenní myelopatie u posttraumatické pseudoartrózy s výhřezem v segmentu C6/7, v terénu staré fraktury u nemocného s AS s typickým počátečním podceněním diagnostiky u nevelkého traumatu. U nemocného následně došlo k typické pozdní deterioraci neurologické-ho stavu. Na našem oddělení jsme dokončili diagnostiku a přistoupili k operaci, se kterou máme největší zkušenosti. Ačkoliv je lehce v rozporu se zavedenými postupy, znamená pro nemocného dostačující řešení i v pooperačním sledování.

Ankylosing spondylitis (AS) or else Bechterew's or Marie-Strümpell's disease is a chronic inflammatory autoimmune disease affecting preferentially the spine in the form of sacroileitis and spondylitis [1,2]. Due to acquired skeletal fragility, compared to healthy spine there is a significantly different response of the organism to the mechanical load [3] and therefore in patients with AS, spinal trauma is much more dangerous. Unlike predominantly elastic injuries in healthy cervical spine in AS patients this elasticity is lost and the spine then behaves like a tubular bone [4,5]. A simple X-ray picture is often insufficient because these fractures are difficult to be found in the field of extensive bone alterations typical for AS [6,7,8]. We present a case report of cervical spondylogenic myelopathy in posttraumatic pseudoarthrosis with a prolapse of C6/7 in the field of an old fracture in an AS patient with a typical initial underestimation of diagnosis in minor trauma. The patient therefore experienced a typical late deterioration of the neurological condition. At our department, we have completed the diagnosis and proceeded to perform the surgery with which we have the greatest experience. Although slightly at variance with established procedures, the surgery provides a sufficient solution for the patient also in postoperative follow-up.
