  abstract  = {Extramedullary disease (EMD) represents a high-risk state of multiple myeloma (MM) associated with poor prognosis. While most anti-myeloma therapeutics demonstrate limited efficacy in this setting, some studies exploring the utility of chimeric antigen receptor (CAR)-modified T cells reported promising results. We have recently designed SLAMF7-directed CAR T cells for the treatment of MM. SLAMF7 is a transmembrane receptor expressed on myeloma cells that plays a role in myeloma cell homing to the bone marrow. Currently, the only approved anti-SLAMF7 therapeutic is the monoclonal antibody elotuzumab, but its efficacy in EMD has not been investigated thoroughly. Thus, we retrospectively analyzed the efficacy of elotuzumab-based combination therapy in a cohort of 15 patients with EMD. Moreover, since the presence of the target antigen is an indispensable prerequisite for effective targeted therapy, we investigated the SLAMF7 expression on extramedullary located tumor cells before and after treatment. We observed limited efficacy of elotuzumab-based combination therapies, with an overall response rate of 40\% and a progression-free and overall survival of 3.8 and 12.9 months, respectively. Before treatment initiation, all available EMD tissue specimens (n = 3) demonstrated a strong and consistent SLAMF7 surface expression by immunohistochemistry. Furthermore, to investigate a potential antigen reduction under therapeutic selection pressure, we analyzed samples of de novo EMD (n = 3) outgrown during elotuzumab treatment. Again, immunohistochemistry documented strong and consistent SLAMF7 expression in all samples. In aggregate, our data point towards a retained expression of SLAMF7 in EMD and encourage the development of more potent SLAMF7-directed immunotherapies, such as CAR T cells.},

  abstract  = {Background The anti-SLAMF7 monoclonal antibody, elotuzumab (elo), plus lenalidomide (len) and dexamethasone (dex) is approved for relapsed/refractory MM in the U.S. and Europe. Recently, a small phase 2 study demonstrated an advantage in progression-free survival (PFS) for elo plus pomalidomide (pom)/dex compared to pom/dex alone and resulted in licensing of this novel triplet combination, but clinical experience is still limited. Purpose To analyze the efficacy and safety of elo/pom/dex in a "real world" cohort of patients with advanced MM, we queried the databases of the university hospitals of W{\"u}rzburg and Vienna. Findings We identified 22 patients with a median number of five prior lines of therapy who received elo/pom/dex prior to licensing within an early access program. Patients received a median number of 5 four-week treatment cycles. Median PFS was 6.4 months with 12-month and 18-month PFS rates of 35\% and 28\%, respectively. The overall response rate was 50\% and 64\% of responding patients who achieved a longer PFS with elo/pom/dex compared to their most recent line of therapy. Objective responses were also seen in five patients who had been pretreated with pomalidomide. Low tumor burden was associated with improved PFS (13.5 months for patients with ISS stage I/II at study entry v 6.4 months for ISS III), although this difference did not reach statistical significance. No infusion-related reactions were reported. The most frequent grade 3/4 adverse events were neutropenia and pneumonia. Conclusion Elo/pom/dex is an active and well-tolerated regimen in highly advanced MM even after pretreatment with pomalidomide.},

  abstract  = {Combined MEK-BRAF inhibition is a well-established treatment strategy in BRAF-mutated cancer, most prominently in malignant melanoma with durable responses being achieved through this targeted therapy. However, a subset of patients face primary unresponsiveness despite presence of the activating mutation at position V600E, and others acquire resistance under treatment. Underlying resistance mechanisms are largely unknown, and diagnostic tests to predict tumor response to BRAF-MEK inhibitor treatment are unavailable. Multiple myeloma represents the second most common hematologic malignancy, and point mutations in BRAF are detectable in about 10\% of patients. Targeted inhibition has been successfully applied, with mixed responses observed in a substantial subset of patients mirroring the widespread spatial heterogeneity in this genomically complex disease. Central nervous system (CNS) involvement is an extremely rare, extramedullary form of multiple myeloma that can be diagnosed in less than 1\% of patients. It is considered an ultimate high-risk feature, associated with unfavorable cytogenetics, and, even with intense treatment applied, survival is short, reaching less than 12 months in most cases. Here we not only describe the first patient with an extramedullary CNS relapse responding to targeted dabrafenib and trametinib treatment, we furthermore provide evidence that a point mutation within the capicua transcriptional repressor (CIC) gene mediated the acquired resistance in this patient.},

  abstract  = {Background: Natural language processing (NLP) is a powerful tool supporting the generation of Real-World Evidence (RWE). There is no NLP system that enables the extensive querying of parameters specific to multiple myeloma (MM) out of unstructured medical reports. We therefore created a MM-specific ontology to accelerate the information extraction (IE) out of unstructured text. Methods: Our MM ontology consists of extensive MM-specific and hierarchically structured attributes and values. We implemented "A Rule-based Information Extraction System" (ARIES) that uses this ontology. We evaluated ARIES on 200 randomly selected medical reports of patients diagnosed with MM. Results: Our system achieved a high F1-Score of 0.92 on the evaluation dataset with a precision of 0.87 and recall of 0.98. Conclusions: Our rule-based IE system enables the comprehensive querying of medical reports. The IE accelerates the extraction of data and enables clinicians to faster generate RWE on hematological issues. RWE helps clinicians to make decisions in an evidence-based manner. Our tool easily accelerates the integration of research evidence into everyday clinical practice.},

  abstract  = {Das multiple Myelom muss trotz aller Therapierfolge in den letzten drei Jahrzehnten seit Einf{\"u}hrung der Melphalan-basierten Hochdosistherapie mit autologer Stammzell-Transplantation als eine unheilbare maligne h{\"a}matologische Systemerkrankung angesehen werden. Trotz einer großen Anzahl vielversprechender neuer Therapieoptionen im Bereich von IMiDs, PIs und g{\"a}nzlich neuer immuntherapeutischer Behandlungsans{\"a}tze stellt dabei die Behandlung eines Myelom-Patienten im sp{\"a}ten Krankheitsrezidiv nach Versagen von Lenalidomid und Bortezomib eine therapeutische Herausforderung dar. Daneben erweisen sich dabei im klinischen Alltag mit zunehmender Zahl an Vortherapien insbesondere auch Behandlungs-assoziierte Toxizit{\"a}ten als den Behandlungserfolg limitierende Faktoren. Diese retrospektive Analyse zeigt, dass eine dritte Melphalan-Hochdosistherapie mit anschließender autologer Stammzelltransplantation in dieser Situation eine wirkungsvolle Therapieoption darstellt, die zum einen ein {\"u}berzeugendes Ansprechen (ORR 59 \%) bewirkt, und {\"u}ber diese unmittelbare Wirksamkeit hinaus zu einem Zugewinn Progressions-freier {\"U}berlebenszeit von im Mittel 9 Monaten f{\"u}hrt. Zudem kann insbesondere auch die neuerliche autologe Transplantation durch eine Verbesserung der h{\"a}ufig Therapie-assoziiert ersch{\"o}pften h{\"a}matopoetischen Funktion dazu beitragen, dass Patienten im nahezu unweigerlich auftretenden neuerlichen Rezidiv durch bessere Therapieadh{\"a}renz und h{\"o}here Therapieintensit{\"a}t maximal von Folgetherapien profitieren. Dieser Effekt spiegelt sich in einem gemessen an einem trotz intensiv vortherapierter Patienten langen mittleren {\"U}berlebens von 26 Monaten wider. Trotz hoher Therapieeffektivit{\"a}t zeigt sich dabei ein g{\"u}nstiges Sicherheitsprofil mit einer Therapie-assoziierten Mortalit{\"a}t von 4,9 \%. Daneben konnte diese Arbeit in einer großen Kohorte best{\"a}tigen, dass eine lange Kryokonservierung autologer Stammzellen nicht nur in vitro sondern auch in vivo nicht zu einem Qualit{\"a}tsverlust und somit beeintr{\"a}chtigtem Stammzell-Engraftment f{\"u}hrt. Insgesamt kann sich die ASCT3 im sp{\"a}ten Krankheitsrezidiv in ihrer Wirksamkeit und Sicherheit in refrakt{\"a}ren/relabierten F{\"a}llen mit Proteasomen-Inhibitoren sowie immunmodulatorischen Substanzen der zweiten bzw. dritten Generation messen lassen, ist jedoch ebenso wenig wie diese im alleinigen Einsatz in der Lage, den negativ-prognostischen Einfluss einer Doppel-Refrakt{\"a}rit{\"a}t bzw. einer Hochrisiko-Zytogenetik vollst{\"a}ndig zu {\"u}berwinden. Hieraus ergeben sich neue Ans{\"a}tze f{\"u}r Therapiekonzepte, die beispielsweise immunmodulatorische Substanzen sowie Proteasomen-Inhibitoren der neueren und neuesten Generation ebenso wie Antik{\"o}rper-basierte Therapien im Rahmen einer prospektiven Studie mit einer dritten Hochdosistherapie und anschließender autologer Stammzelltransplantation kombinieren k{\"o}nnten, um das Gesamt{\"u}berleben von Myelom-Patienten weiter zu verl{\"a}ngern.},

  abstract  = {Background: Therapy for multiple myeloma (MM) has substantially improved in the era of immunomodulatory drugs and bortezomib. However, the prognosis of patients with progressive disease despite treatment with these 'novel agents' remains poor. Recently, pomalidomide was approved in this setting, but a median progression-free survival of <4 months still leaves room for improvement. Pomalidomide-based combination therapies are currently under investigation, but data on long-term treatment are lacking. Case Report: We present the case of a 68-year-old woman with refractory MM who received pomalidomide in combination with various drugs including anthracyclines, alkylators and proteasome inhibitors. Initially, major hematological toxicities and infectious complications including a hepatitis B virus reactivation were encountered. With careful dose adjustments and selection of combination partners, pomalidomide treatment was maintained for over 4 years and led to a sustained partial remission. In particular, the well-tolerated regimen of bortezomib, cyclophosphamide and dexamethasone together with pomalidomide was administered for >30 cycles. Conclusion: This case illustrates the value of an individualized approach to myeloma care given an increasing availability of 'novel agents'. Tailored treatment using these drugs as a backbone is essential to achieve long-lasting responses and minimize side effects.},
