Introduction: Ibrutinib works by inhibiting downstream signaling after the interaction between the mutated MYD88 (Leu265Pro) protein and BTK. In 2015, Ibrutinib, an inhibitor of Bruton's tyrosine kinase (BTK), was approved by the U.S Food and Drug Administration (FDA) for patients with symptomatic Waldenstrom Macroglobulinemia (WM). Methods: We performed a comprehensive literature search following PRISMA guidelines. Beginning with articles published after April 2015, we used databases like PubMed, Embase, Clinicaltrials.gov, Cochrane Library, and Web of Science. A total of 580 articles were identified initially, and after a detailed screening, we finalized 4 studies involving 248 WM patients. Results: The total number of patients who received Ibratunib based regimens were 248. The dose ranged from 140-560 mg. The overall response rate ranged from 90-92%, very good partial response ranged from 13-23%, and the partial response ranged from 36-75%. 1) Ibtrutunib +Rituximab: In a study by Dimopoulos et al., (N=150), the overall response rate (ORR) was 92% vs 47% in control vs placebo respectively. The progression-free survival (PFS) of 30 months was 82% vs 28% respectively. 2) Ibrutinib alone: In a study by Dimopoulos et al., with (N=31), ORR was 90%, a very good progression rate (VGPR) was 13 %, and the partial response (PR) was 58%. In a study by Treon et al., (N=63) ORR was observed in Treon et al. at 90.50%, VGPR was 15%, PR was 36%, no response (NR) was 57%, with overall survival (OS) was 24 months. In a study by Richard et al., (N=4), PR was noted at 75%. Conclusion: Ibtrutunib used for the treatment of WM showed an overall response rate of 92%. Infections, cytopenia, bleeding, hypertension and atrial fibrillation were major side effects reported. However, due to the recent FDA approval of the drug to be used for the patients of WM there is very limited studies on Ibrutinib. We recommend future randomized prospective trials to understand the efficacy and safety profile of Ibrutinib for WM treatment.

Introduction: There are about 1500 cases every year in the United States of America and while the disease is incurable but it is treatable. Purine analogs are anti-metabolites that mimic the structure of metabolic purines and are used for the treatment of Waldenstrom macroglobulinemia (WM). Methods: We performed a comprehensive literature search on articles following PRISMA guidelines. Beginning with articles published after 1995, we used databases like PubMed, Embase, Clinicaltrials.gov, Cochrane Library and Web of Science. Total 580 articles were identified initially and after detailed screening, we finalized 16 studies involving patients with Waldenstrom macroglobulinemia. Results: The total number of patients in the studies involving regimens based on purine analogs were 1211. The doses of Fludarabine ranged from 25-30 mg/m2 and that of Cladribine ranged from 0.1-0.5 mg/kg. The complete response (CR) observed ranged from 2-15% and the partial response (PR) ranged from 11-67%. The overall response rate (ORR) ranged from 38-95%. Fludarabine: In the study Dhodapkar et al., N=231, the highest CR and ORR was observed, 4% and 66% respectively. In the study Zinzani et al., the PR was 41%. Fludarabine and Cyclophasphamide: In the study Dimopoulos et al., the PR was 55% and the progression free survival (PFS) was 24 months. Fludarabine, Cyclophosphamide and ofatumumab: In the study Gavriatopoulou et al., the PR was 67% and very good partial response (VGPR) was 17% and the PFS was 23 months. Fludarabine, rituximab and cyclophosphamide: In the study Tedeschi et al., the CR was 11.60%, ORR was 79% and the PR was 41.8%. Fludarabine and Rituximab: In the study Treon et al., the CR was 4.6%, VGPR was 32.5%, PR was 48%, and ORR was 95.3% with PFS of 51.2 months. Cladribine: In the study Liu et al., the CR was 5% and PR was 50%. In the studies Dimopoulos et al., 1994 the highest CR was observed, 11.5% with an ORR of 85%. The PR was also the highest, 73%. Conclusion: There is limited literature on regimens containing both Fludarabine and Cladribine, which are used for the treatment of WM. Despite heterogenicity in WM patients and various regimens used in literature. Purine analogs containing regimens are a remarkably effective treatment with overall response rates reaching up to 79%. Neutropenia and thrombocytopenia were the main side effects. There is a paucity of phase 3 randomized trials demonstrating a clinical benefit of anyone regimen over another. We recommend future randomized prospective trials better to understand the efficacy and safety profile of regimens containing purine analogs.

Introduction: Waldenström macroglobulinemia (WM) is a B-cell lymphoproliferative disorder characterized by lymphoplasmacytic bone marrow infiltration and immunoglobulin M (IgM) monoclonal gammopathy. Various studies have shown that the proteasome inhibitor bortezomib (V) targets signaling pathways of relevance in WM. We reported published data on the efficacy profile of (V) for the patients of WM. Methods: We performed a comprehensive literature search on articles following PRISMA guidelines. Beginning with articles published after 2004, we used databases like PubMed, Embase, Clinicaltrials.gov, Cochrane Library and Web of Science. Total 580 articles were identified initially and after detailed screening, we finalized 9 studies involving 375 patients with Waldenstrom Macroglobulinemia (WM) treated by combination of Bortezomib. Results: The total number of patients in the studies involving Bortezomib were 375 and dose of the drug used ranged between 1.3 mg/m2 to 1.6mg/m2. The Complete response (CR) ranged from 0-19% and the partial response (PR) ranged from 44-58%. Bortezomib(V): In the study Treonet et al., N=27, the highest major respose rate was 85% and minimal response rate was 37%. In the study Chen et al., N=27, the major response rate was 26% and the PR was 44%. Progression free survival (PFS) was 16.3 months for Chen et al. Bortezomib(V), Rituximab(R), and Dexamethasone(D): In the study Treon et al., N=23, the highest major response rate was 96%, CR was 13%, Very good partial response (VGPR) was 13%, and PR was 46%. Highest PR and was observed in Dimopolous et al., which was 58% and 42 months respectively. Bortezomib(V), and Rituximab(R): In the study Agathocleus et al., N=42, the highest CR was 14.2-19%. The highest PR was between 47.6-52.3%. In the study Ghobrial et al., N=37, the CR was 3% and PR was 46%. PFS was 15.6 months. Bortezomib(V), Rituximab(R) and Everolimus(E): In the study Ghobrial et al., N=46, the CR was 4%, PR was 46% and PFS was 18 months. Conclusion: Despite heterogenicity in WM patients and various regimens used in literature, Bortezomib containing regimens are a remarkably effective treatment. Combination regimens showed an overall response rate of 96%. The main side effects being anemia, leukopenia, thrombocytopenia, nausea and sensory neuropathies. Although we recommend future randomized prospective trials to better understand the efficacy and safety profile of Bortezomib for WM treatment.

Abstract INTRODUCTION: Previous studies have demonstrated the clinical activity of the mTOR inhibitor RAD001 in low- grade lymphomas. Our preclinical studies demonstrated activity of mTOR inhibitors in Waldenstrom Macroglobulinemia (WM) cell lines and patient samples. This phase II study aimed to determine safety and activity of the oral mTOR inhibitor RAD001 (Novartis Pharmaceutical, MA) in patients with relapsed or refractory WM. METHODS: Patients who had at least one previous therapy for WM, and who had symptomatic relapsed or refractory disease were eligible. NCI CTCAE v3.0 was used for toxicity assessment. All patients received daily RAD001 at 10 mg. A cycle was considered 28 days. Patients were allowed to stay on therapy until progression of disease or excessive toxicity. This study was conducted in a collaborative effort between Dana Farber Cancer Institute (DFCI) and Mayo Clinic College of Medicine. Here, we report the data on the patients accrued at DFCI. RESULTS: 19 pts (15 men and 4 women) have been treated to date. All patients had symptomatic disease and required therapy. The median number of lines of prior treatment was 3 (range 1 – 5) including included rituximab, nucleoside analogues (fludarabine or 2-CDA), combination chemotherapy (e.g. CHOP, CVP), chloramucil, and bortezomib. The median IgM at baseline was 3330 mg/dL (range 1010– 7410). The median follow on RAD001 was 8 months (range 3 – 22 months). Eighteen pts are currently evaluable for response. Best responses to RAD001 after 2 cycles using IgM monoclonal protein were as follows: partial remission in 8 (44%), minimal response in 5 (28%). Progressive disease occurred in 4 (22%) and stable disease occurred in 1 (6%). The overall response rate (PR+MR) was 72%. The median duration of response has not been reached (3–22+ months). Patients tolerated therapy well without significant toxicities. Grade 3 and 4 toxicities included grade 4 thrombocytopenia in 1 patient, grade 3 pneumonia in 1 patient, grade 3 hyperglycemia in 1 patient and grade 3 mucositis in 1 patient. Other adverse events of grade 2 or lower included nail cracking, mucositis, diarrhea, and fatigue. Attributable toxicities otherwise proved manageable with appropriate supportive care, and RAD001 was generally well tolerated. One patient enrolled on the study withdrew consent and changed to hospice care within 3 weeks of therapy, and passed away due to disease progression. CONCLUSIONS: The use of the oral RAD001 single agent RAD001 in patients with relapsed or refractory WM was welltolerated and demonstrated significant activity achieving an overall response rate in 72% of patients. Future studies of combination of this agent with rituximab and bortezomib are currently being planned.

Purpose The phosphatidylinositol 3-kinase/mammalian target of rapamycin (mTOR) signal transduction pathway controls cell proliferation and survival. Everolimus is an oral agent targeting raptor mTOR (mTORC1). The trial's goal was to determine the antitumor activity and safety of single-agent everolimus in patients with relapsed/refractory Waldenström macroglobulinemia (WM). Patients and Methods Eligible patients had measurable disease (immunoglobulin M monoclonal protein > 1,000 mg/dL with > 10% marrow involvement or nodal masses > 2 cm), a platelet count more than 75,000 × 106/L, a neutrophil count more than 1,000 × 106/L, and a creatinine and bilirubin less than 2 × the laboratory upper limit of normal. Patients received everolimus 10 mg orally daily and were evaluated monthly. Tumor response was assessed after cycles 2 and 6 and then every three cycles until progression. Results Fifty patients were treated. The median age was 63 years (range, 43 to 85 years). The overall response rate (complete response plus partial remission [PR] plus minimal response [MR]) was 70% (95% CI, 55% to 82%), with a PR of 42% and 28% MR. The median duration of response and median progression-free survival (PFS) have not been reached. The estimated PFS at 6 and 12 months is 75% (95% CI, 64% to 89%) and 62% (95% CI, 48% to 80%), respectively. Grade 3 or higher related toxicities were observed in 56% of patients. The most common were hematologic toxicities with cytopenias. Pulmonary toxicity occurred in 10% of patients. Dose reductions due to toxicity occurred in 52% of patients. Conclusion Everolimus has high single-agent activity with an overall response rate of 70% and manageable toxicity in patients with relapsed WM and offers a potential new therapeutic strategy for this patient group.

Abstract We present the results of a phase 2 study evaluating the combination of obinutuzumab + idelalisib in relapsed/refractory (R/R) Waldenström macroglobulinemia (WM). The goal was to determine the safety and efficacy of a fixed-duration chemotherapy-free treatment. During the induction phase, patients received idelalisib + obinutuzumab for 6 cycles, followed by a maintenance phase with idelalisib alone for ≤2 years. Forty-eight patients with R/R WM were treated with the induction combination, and 27 patients participated in the maintenance phase. The best responses, reached after a median of 6.5 months (interquartile range, 3.4-7.1; range, 2.6-22.1 months), were very good partial response in 5 patients, partial response in 27 patients, and minor response in 3 patients, leading to overall response rate and major response rate estimates of 71.4% (95% confidence interval [CI], 56.7-83.4) and 65.3% (95% CI, 50.4-78.3), respectively. With a median follow-up of 25.9 months, median progression-free survival was 25.4 months (95% CI, 15.7-29.0). Univariate analysis focusing on molecular screening found no significant impact of CXCR4 genotypes on responses and survivals but a deleterious impact of TP53 mutations on survival. Although there was no grade 5 toxicity, 26 patients were removed from the study because of side effects; the most frequent were neutropenia (9.4%), diarrhea (8.6%), and liver toxicity (9.3%). The combination of idelalisib + obinutuzumab is effective in R/R WM. Nonetheless, the apparent lack of impact of genotype on outcome could give new meaning to targeting of the phosphatidylinositol 3-kinase pathway in WM. This trial was registered at www.clinicaltrials.gov as #NCT02962401.

Εισαγωγή: O καρκίνος του πνεύμονα αποτελεί το 28% όλων των θανάτων που σχετίζονται με καρκίνο και περίπου στο 80% των περιπτώσεων αφορά στο Μη Μικροκυτταρικό καρκίνωμα. H σισπλατίνη είναι από τα δραστικότερα και πιο αποτελεσματικά κυτταροτοξικά φάρμακα στη θεραπεία των επιθηλιακών κακοηθειών, που όμως οι σοβαρές ανεπιθύμητες ενέργειες και η αντίσταση στην χορήγηση της, εγείρουν την ανάγκη βελτιωμένων μορφών αυτού του φαρμάκου. Mία λιποσωμιακή μορφή της σισπλατίνης, είναι η Λιποπλατίνη (Lipoplatin™), η οποία αναπτύχθηκε με σκοπό να μειώσει τη συστηματική τοξικότητα της σισπλατίνης και να αυξήσει τη δραστικότητά της έναντι των όγκων. Σκοπός: Η ανάλυση και εκτίμηση των απεικονιστικών ευρημάτων, στα οποία κατά κύριο λόγο βασίζεται η αξιολόγηση της ανταπόκρισης στη χημειοθεραπεία (σύμφωνα με τα κριτήρια RECIST 1.1) η συσχέτιση τους με τον ιστολογικό τύπο του καρκίνου σε ασθενείς που λαμβάνουν μέρος σε τυχαιοποιημένη, συγκριτική, ανοιχτής αγωγής, προοδευτική μελέτη φάσης II και η εκτίμηση του ποσοστού αντικειμενικής ανταπόκρισης (Overall Response Rate-ORR) στους ασθενείς των δύο ομάδων. Οι συνδυασμοί χημειοθεραπείας είναι για την πρώτη ομάδα της μελέτης, Λιποπλατίνη και γεμσιταβίνη, ενώ για την δεύτερη ομάδα σισπλατίνη και γεμσιταβίνη, ως θεραπείες πρώτης γραμμής σε Μη Μικροκυτταρικού τύπου, καρκίνο του πνεύμονα (Στάδιο IIIβ/ IV).Δευτερεύοντες στόχοι είναι να συγκριθούν στις δύο ομάδες : το ποσοστό ελέγχου της ασθένειας (DCR), η επιβίωση χωρίς εξέλιξη της νόσου (PFS), η διάρκεια της ανταπόκρισης, η συνολική επιβίωση, η ασφάλεια και η ανεκτικότητα του συνδυασμού θεραπείας.Ασθενείς και Μέθοδος: Η Μελέτη πραγματοποιήθηκε στο νοσοκομείο Μεταξά (2η παθολογική κλινική, υπεύθυνος ερευνητής: Μυλωνάκης Νικόλαος). Τα βασικά κριτήρια συμπερίληψης ασθενών στη μελέτη είναι η ιστολογικά ή κυτταρολογικά επιβεβαιωμένη διάγνωση Μη μικροκυτταρικού καρκίνου του πνεύμονα (NSCLC) σε ασθενείς άνω των 18 ετών με τοπικά προχωρημένο ή μεταστατικό NSCLC.Τα κυριότερα κριτήρια αποκλεισμού είναι η προηγηθείσα χορήγηση άλλου είδους χημειοθεραπεία, βεβαρημένο ιατρικό ιστορικό και η είσοδος στη μελέτη σε χρονικό διάστημα λιγότερο των 3 εβδομάδων από μεγάλη χειρουργική επέμβαση.Οι ασθενείς τυχαιοποιούνται κεντρικά κατά την εισαγωγή τους στην ομάδα Α (Λιποπλατίνη και γεμσιταβίνη) ή στην ομάδα Β (σισπλατίνη και γεμσιταβίνη). Τo θεραπευτικό σχήμα της ομάδας A αποτελείται από: Λιποπλατίνη 120 mg/m2 (ημέρες 1, 8, 15 σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους) και γεμσιταβίνη 1000 mg/m2 (ημέρες 1, 8 σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους). Στην ομάδα Α δεν θα γίνεται προ- ή μετά- ενυδάτωση και δεν θα χρησιμοποιείται φυσιολογικός ορός, ενώ ο ρυθμός έγχυσης θα πρέπει να είναι αργός ιδίως στην αρχή αυτής. Το σχήμα της ομάδας B (χημειοθεραπευτική αγωγή αναφοράς) αποτελείται από σισπλατίνη 100 mg/m2 (ημέρα 1, σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους) και γεμσιταβίνη 1000 mg/m2 (Hμέρες 1, 8 σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους). Η σισπλατίνη θα χορηγείται ως δίωρη ενδοφλέβια έγχυση με ένα λίτρο φυσιολογικού ορού προενυδάτωση και βεβιασμένη διούρηση. Σε αμφότερες τις ομάδες θα συνεχιστεί η ίδια θεραπευτική αγωγή για 3 κύκλους επιπλέον, κατόπιν ανταπόκρισης ή σταθεροποίησης της νόσου. Η αξιολόγηση των ασθενών θα γίνεται σε 4 χρονικές περιόδους: πριν από την έναρξη της θεραπείας, εβδομαδιαία αξιολόγηση (την έβδομη ημέρα μετά από κάθε έγχυση), μετά από 3 και 6 κύκλους θεραπείας και κάθε 3 μήνες δια βίου. Ο έλεγχος των ασθενών θα περιλαμβάνει ιατρικό ιστορικό, φυσική εξέταση, γενική αίματος και πλήρη βιοχημικό έλεγχο με καταγραφή των ανεπιθύμητων ενεργειών. Η αξιολόγηση των ασθενών απεικονιστικά πριν την έναρξη και μετά από 3 και 6 κύκλους θεραπείας. Οι απεικονιστικές μέθοδοι περιλαμβάνουν ακτινογραφία και αξονική τομογραφία θώρακος, αξονικές τομογραφίες κοιλίας, εγκεφάλου και σπινθηρογράφημα οστών αν είναι απαραίτητο. Όλες οι απεικονιστικές εξετάσεις θα διενεργούνται σύμφωνα με τα συνήθη διεθνή πρωτόκολλα, όχι απαραίτητα σε προεπιλεγμένα κέντρα αφού η εισαγωγή και παρακολούθηση των ασθενών στη μελέτη θα πραγματοποιείται κατόπιν διάγνωσης NSCLC σε οποιοδήποτε κέντρο.Αποτελέσματα: Τα απεικονιστικά ευρήματα ανά ιστολογικό τύπο, των ασθενών που έλαβαν μέρος στη μελέτη δεν ήταν διαφορετικά από αυτά που αναφέρονται στην βιβλιογραφία. Η εντόπιση του αδενοκαρκινώματος είναι στις περισσότερες περιπτώσεις περιφερική. Το καρκίνωμα εκ πλακωδών κυττάρων έχει κεντρική εντόπιση στο μεγαλύτερο ποσοστό των ασθενών. Στο σύνολο των ασθενών η εντόπιση υπερέχει στον δεξιό πνεύμονα και στον άνω λοβό. Η κοιλοποίηση, οι αποτιτανώσεις και η προσβολή των πλευρών είναι πιο συχνή στο εκ πλακωδών κυττάρων καρκίνωμα. Η ανάλυση της αποτελεσματικότητας της μελέτης πραγματοποιήθηκε με βάση τα απεικονιστικά ευρήματα χρησιμοποιώντας τα κριτήρια RECIST 1.1. Μερική ανταπόκριση (Partial Response-PR) μετά από την ολοκλήρωση 3 κύκλων παρουσίασε το 31,7% των ασθενών στο Α σκέλος και το 25,6% στο Β αντίστοιχα. Σταθερή νόσος (Stable Disease-SD) παρατηρήθηκε στο 39% των ασθενών στο Α σκέλος, ενώ στο Β ήταν 30,8%. Σε κανένα σκέλος δεν υπήρξε πλήρης ανταπόκριση (Complete Response-CR). Αν και η διαφορά στην ανταπόκριση μεταξύ των δύο ομάδων δεν είναι στατιστικά σημαντική ωστόσο τα αποτελέσματα είναι ενθαρρυντικά αφού η Λιποπλατίνη όχι μόνο δεν υπήρξε υποδεέστερη της σισπλατίνης αλλά επιπλέον είχε μικρότερη τοξικότητα συγκριτικά με την σισπλατίνη. Μια διαφορά που ήταν στατιστικά σημαντική μεταξύ των δύο ομάδων ήταν στη νεφροτοξικότητα. Επιπροσθέτως στην περίπτωση του αδενοκαρκινώματος φαίνεται ότι η Λιποπλατίνη έχει πολύ καλύτερη ανταπόκριση συγκριτικά με την σισπλατίνη (16,7% πρόοδο νόσου έναντι 45,8%) ενώ στην περίπτωση του καρκινώματος εκ πλακωδών κυττάρων τα αντίστοιχα ποσοστά ήταν 46,1% και 37,5%. Συμπέρασμα: Η λιποσωμιακή μορφή της σισπλατίνης παρουσιάζει λιγότερες παρενέργειες συγκριτικά με την σισπλατίνη όταν συνδυάζεται με την γεμσιταβίνη και ειδικότερα στατιστικά σημαντική μικρότερη νεφροτοξικότητα. Ιδιαίτερα σημαντικό επίσης είναι το γεγονός ότι στους ασθενείς της ομάδας που έλαβαν Λιποπλατίνη δεν έγινε προ ενυδάτωση ούτε βεβιασμένη διούρηση. Επιπροσθέτως η Λιποπλατίνη παρουσιάζει μία μεγαλύτερη αποτελεσματικότητα η οποία δεν είναι στατιστικά σημαντική λόγω του μικρού δείγματος ασθενών ωστόσο στην περίπτωση του αδενοκαρκινώματος παρουσιάζει μία στατιστικά σημαντική διαφορά στην ανταπόκριση έναντι της σισπλατίνης.

Abstract Based on data previously presented by our group demonstrating the safety and efficacy of lenalidomide (L) and rituximab (R) in the upfront setting, we are conducting an open-label, phase 2 trial single center trial to evaluate this combination as treatment for patients with relapsed or refractory CLL. Methods Patients started L at 5 mg per day and could escalate to 25 mg/day if tolerated. Patients received L for 21 of 35 days for cycle 1, then 21 of 28 days for cycles 2 to 7. Rituximab was started at the end of C1 at 50 mg/m2 on Day 29, 325 mg/m2 on day 31 and 33, then 375mg/m2 weekly x4 for cycle 2, and on day 1 for cycles 3-7. Patients who achieved a response but had residual disease after 7 cycles were given the option to continue single-agent L in a consolidative manner for 6 additional cycles. All patients received allopurinol 300mg daily and aspirin 81mg daily, unless contraindicated. The primary endpoint was overall response rate by iwCLL guidelines following 7 cycles. This abstract reports on the planned interim analysis of the safety and efficacy. Results By April 2013, 24 patients were enrolled and received treatment. 63% of patients were male (15/24). The median age at the start of study treatment was 67 years (range 53-83), with median 2.5 prior therapies (range 1-7). 75% (18/24) had CLL cells that expressed unmutated IgVH genes or high levels of ZAP-70. 25% (6/24) had unfavorable cytogenetics (del 17p or del 11q). 5 patients stopped therapy early due to toxicity. 2 patients stopped treatment due to grade 3 tumor flare reaction. 1 patient developed grade 4 tumor lysis requiring hemodialysis. 1 patient had grade 4 neutropenia within days of starting L. 1 patient developed a deep vein thrombosis during cycle 2 while off aspirin for transient thrombocytopenia. These patients tended to have a higher baseline absolute lymphocyte count, but this association did not meet statistical significance. Treatment was otherwise well tolerated. Neutropenia was the most common adverse event (AE), with grade 4 (by CTCAE 4) in 9 patients, and grade 3 in 6 patients out of 21 evaluable patients. There was a single instance of grade 4 thrombocytopenia, and 4 patients had grade 3 thrombocytopenia. 3 patients had grade 3 anemia. The only other grade 3 or higher AE was fatigue (5%). Of note, grade 2 superficial thrombophlebitis occurred in 3 patients. Out of the 20 patients whose primary endpoints were assessed, the overall response rate (ORR) was 70% (14/20) with 15% nodular partial response (3 patients) and 55% partial response (PR) (11 patients). 30% (6/20) were non-responders (NR). Only 1 of the 6 patients with NR had objective progressive disease (PD). The other 5 patients stopped treatment early due to toxicity and were designed as non-responders. Of the responder patients, 8 elected to receive an additional 6 months of consolidation lenalidomide. All maintained the same response without meeting objective criteria for either PD or complete response. After a median follow-up of 17 months from the start of treatment, there have been no deaths among the 24 patients. For the 20 evaluable patients, the median progression free survival (PFS) was 18.4 months and the median treatment free survival was 13.5 months.We did not find any significant association between response, toxicity, or PFS and any demographic or prognostic variable analyzed, including age, ZAP-70, IgVH mutation, cytogenetics, splenomegaly, or CLL cell immunophenotype. Conclusions The combination of lenalidomide and rituximab is an effective regimen for the treatment of patients with relapsed or refractory CLL with an ORR and PFS that rivals novel CLL therapies, especially for patients continued on lenalidomide consolidation therapy. The median PFS for all patients is in excess of 1.5 years after a median follow-up of 17 months. A subset of patients encountered adverse events requiring early treatment cessation, but only 1 patient progressed on treatment. Continued accrual will facilitate the identification of biologic or clinical factors that may predict such outcomes. Disclosures: Choi: Celgene: Research Funding. Castro:Celgene: Research Funding.

Abstract Background Olaptesed pegol (NOX-A12) is a novel, potent, L-stereoisomer RNA aptamer that binds and neutralizes CXCL12/SDF-1, a chemokine which attracts and activates immune- and non-immune cells via interaction with the receptors CXCR4 and CXCR7. Signaling of CXCL12 is pivotal to the interactions of leukemic cells with bone marrow microenvironment. The therapeutic concept of olaptesed is to inhibit such tumor-supporting pathways and thereby mobilizing and sensitizing CLL cells to therapy. Here we aim to assess the activity and safety of olaptesed in combination with bendamustine and rituximab (BR) in patients with relapsed / refractory CLL. Methods Twenty-eight relapsed or refractory CLL patients were enrolled and treated in this open-label, single-arm Phase IIa study. To investigate PK/PD, a pilot dose of 1 to 4 mg/kg olaptesed alone was administered to 3 patients per dose group (plus one additional replacement pt) before start of the regular treatment regimen (pilot group). Patients were treated using a dose titration design with intravenous (IV) olaptesed at doses increasing from 1 mg/kg to 2 mg/kg and 4 mg/kg at cycles 1, 2 and 3, respectively, at 1 hour before rituximab treatment. During cycles 4 to 6, olaptesed was dosed at the highest individually titrated dose. Rituximab was administered IV at doses of 375 mg/m² on day 1 of the 1st28-day cycle and 500 mg/m² on day 1 of subsequent cycles. Bendamustine (70 - 100 mg/m²) was given IV on days 2-3 (cycle 1) or days 1-2 (cycles 2-6) of each 28-day cycle following administration of rituximab. Clinical response was assessed according to NCI-WG Guidelines (Hallek M et al. Blood 111; 2008: 5446-56). Results To date, 24 patients completed treatment (12 women, 12 men) with a median age of 68.5 years (range 52 to 79). At screening 5, 9 and 10 patients presented with Binet stage A, B and C, respectively. The median number of prior treatment lines was 1 (range 1-2). Seven high-risk patients presented an unfavorable disease state being relapsed within 24 months after fludarabine/bendamustine treatment (5 pts) and/or presenting a deletion/mutation of the TP53 gene (3 pts). Most patients (19 of 24) were previously treated with fludarabine or bendamustine. A flow cytometric analysis of CD19+/CD5+CLL cells showed a rapid mobilization into the peripheral blood by a single dose of olaptesed which lasted throughout the observational time of 72h. Interestingly, CXCR4 expression levels increased on CLL cell surface in the periphery after olaptesed treatment. This increase, which peaked at 24h, likely reflects the extended circulation of CLL cells in the periphery due to the sustained blockade of CXCL12 by olaptesed. Reduction of lymphadenopathy by ≥ 50% was achieved in 14 out of 21 evaluable patients with reported enlarged lymph nodes by the end of treatment. Concomitantly, rapid reduction of lymphocytosis in peripheral blood with normalization by treatment cycle 2 – 3 was observed and the CLL to leukocyte ratio significantly improved. Efficacy was assessed at the end of cycles 3 and 6. In the full-analysis-set, which excludes two non-evaluable patients (drop-out after the 1st cycle due to adverse events), the overall response rate was 96%: Three patients (14%) achieved a complete response at end of cycle 6 (2 confirmed, 1 investigator reported) and eighteen patients (82%) achieved a partial response (fifteen at end of cycle 6 and three at end of cycle 3). Notably, all seven high-risk patients (defined as relapsed within 24 months after fludarabine/bendamustine treatment and/or presenting a deletion/mutation of the TP53 gene) responded to treatment with olaptesed + BR with a partial response. One patient had a progressive disease. Olaptesed at 1, 2 and 4 mg/kg at a single dose and in combination with BR was safe and well tolerated. The observed adverse reactions were qualitatively and quantitatively as expected for patients treated with BR. Conclusion Olaptesed in combination with BR was safe and well tolerated. Compared with historical data, olaptesed showed superiority over baseline therapy with regards to overall response rate and increasing rates of complete remission, warranting further development of this Spiegelmer in CLL.

Waldenström's Macroglobulinemia

Introduction: Waldenström's macroglobulinemia is a rare low-grade lymphoplasmacytic lymphoma characterized by CD20 expression on malignant cells and produces a monoclonal immunoglobulin M (IgM). Rituximab is a chimeric monoclonal antibody against CD20 antigen and the most widely used therapeutic agents in WM. Rituximab works by adhering to CD20, causes B-cell lysis mainly through antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity. Cyclophosphamide is an alkylating agent binds to DNA. Its cytotoxic effect is mainly due to cross-linking of strands of DNA and RNA, and to inhibition of protein synthesis. Our objective is to analyze and summarize the published literature for the efficacy of regimens containing both rituximab and cyclophosphamide for the treatment of Waldenström's macroglobulinemia (WM). Methods:We performed a comprehensive literature search on articles following PRISMA guidelines. Beginning with articles published after January 2005, we used databases like PubMed, Embase, Clinicaltrials.gov, Cochrane Library, and Web of Science. A total of 585 articles were identified initially, and after a detailed screening, we finalized 10 studies involving 425 WM patients. Results:The total number of patients were 425. The dose was 375 mg/m2. The complete response (CR) ranged from 3-19%, very good partial response (VGPR) ranged from 4-22%, and the partial response (PR) ranged from 8-82%. The overall response rate (ORR) ranged from 79-95%. Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (R-CHOP): In a retrospective study by Ioakimidis et al., included 23 WM patients were given R-CHOP. The ORR was 95%, with 69% achieving a major response, 43%, PR, and VGPR OF 9%. In a randomized control trial by Buske et al., N=23, the major response rate was 91%, and PR was 82%. Treon et al. (N=13) observed a major response rate of 27%. (Table 1). Fludarabine, Cyclophosphamide and Rituximab (FCR): In a retrospective study by Peinert et al., involving 29 patients receiving the FCR regimen, the ORR was 90%, with 79%, 3%, and 10% of patients achieving PR, CR, and NR, respectively. In a study by Tedeschi et al., involving 40 patients, ORR was 80%, and the major response rate was 80%. Souchet et al., N=82 reported an ORR of 84% and a PR of 46%. Progression-free survival (PFS) was 51.2 months for Tedeschi et al. Dexamethasone, Rituximab and Cyclophosphamide (DRC) In study Paludo et al., (N=50), receiving the DRC regimen, the highest ORR was 87%, PR 64%, and major response was 68%. In a phase II study by Dimopoulos et al., (N=72), the ORR of 82% and PR of 67% was observed. PFS was 24 months in this study. (Table 1) 4.Rituximab, Cyclophosphamide, Vincristine, and Prednisone (R-CVP) In study Ioakimidis et al, N=16, the ORR was 87%, the major response rate was 62%, and the PR was 43%. Rituximab, Cyclophosphamide, and Prednisone (RCP) Ioakimidis et al., reported 19 patients who were given RCP. The ORR, PR, and the major response rate was 94%, 73%, and 73%, respectively.Lenalidomide, Rituximab, Cyclophosphamide, and Dexamethasone (LR-CD) A study by Rosenthal et al., 15 patients were given LR-CD. ORR was 80%, with a major response rate in 80% and PR in 73% of patients. PFS was 38 months. Conclusion: Rituximab and cyclophosphamide, in combination regimens for the treatment of WM showed the overall response rate of 95%. Neutropenia was the dominant side effect reported in these regimens. There is a paucity of phase 3 randomized trials demonstrating a clinical benefit of anyone regimen over another. We recommend future randomized prospective trials better to understand the efficacy and safety profile of regimens containing both rituximab and cyclophosphamide base combinations.
