PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Purpose Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. Patients and Methods We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). Results In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. Conclusion Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.

Abstract Bortezomib is a targeted proteosome inhibitor licensed & approved for in multiple myeloma both as first line and in relapsed setting. This is a retrospective non experimental cross sectional quantitative comparative group study using clinical case notes, laboratory & pharmacy records for patients treated with Bortezomib in 2011 & 2012. Outcomes studied included remission status, adverse events, progression free survival and overall survival at follow up. The study also looked at the comparative responses of cohort of patients administered Bortezomib through intravenous & subcutaneous route. The cohort consisted of 33 patients, 21 male, 11 female, median age 71 years, first line 10 patients, second line 23 , median number of cycles in 2011 & 2012 – first line 3 & 8 , second line 5 & 4, respectively. In 2011, 8 received intravenous treatment, 9 were switched from intravenous to subcutaneous route whilst all patients from 2012 received subcutaneous Bortezomib. The most frequently used regimen was Bortezomib Dexamethasone ( VD). The overall response rate ( ORR >/= Minor Response) was: First line 70% (7/10) ; Second line 47.8% ( 11/23); median PFS ( Figure 1) 6 months ( First line: 7 months ; Second line : 6 months) and median overall survival ( Figure 2) at follow up: 9 months ; 39.4 % ( 13/33) First line 8.5 months, Second line 11 months. Subcutaneous Bortezomib was equivalent to intravenous Bortezomib in terms of efficacy & tolerance. Of 33 patients, there were 12 dose reductions. Adverse events reported included: peripheral Neuropathy - grade 3 - 6% ( all grades 27.3%); Diarrhoea - grade 3 - 3% (all grades 6%); Nausea / Vomiting - grade 3 - 3% ( all grades 6%) and Second Primary Malignancies - 12% ( 4 of 33). Mortality at follow up was 20 patients from cohort of 33 ; causes included disease progression in 11, second primary malignancy with disease progression in 4, COPD 2, Systemic Amyloidosis 2, Tuberculosis 1 , Multiple co morbidities 1 and Asthma with mechanical failure in single patient. Second primary malignancies ( 4/33) included Prostate carcinoma ( 1), Renal Cell Carcinoma (1), Neuroendocrine tumour ( 1 ) and Unknown Primary in single patient. Beyond second line treatment, majority (14 of 23 patients; 60.9 %) did not have further active treatment. These data indicate that patient outcomes were modest compared to published data from VISTA and APEX trials. Majority of patients did not have further active treatment beyond second line which suggests the most effective treatment strategy should be used upfront as patients may not be fit to have further lines of therapy despite availability of recently introduced novel targeted agents. A higher percentage of second primary malignancies were noticed in this cohort which should be an area of further clinical research.

Abstract Background Proteasome inhibitors (PIs), including carfilzomib, potentiate the activity of selinexor, a novel, first-in-class, oral selective inhibitor of nuclear export (SINE) compound, in preclinical models of multiple myeloma (MM). Methods The safety, efficacy, maximum-tolerated dose (MTD) and recommended phase 2 dose (RP2D) of selinexor (80 or 100 mg) + carfilzomib (56 or 70 mg/m2) + dexamethasone (40 mg) (XKd) once weekly (QW) was evaluated in patients with relapsed refractory MM (RRMM) not refractory to carfilzomib. Results Thirty-two patients, median prior therapies 4 (range, 1–8), were enrolled. MM was triple-class refractory in 38% of patients and 53% of patients had high-risk cytogenetics del(17p), t(4;14), t(14;16) and/or gain 1q. Common treatment-related adverse events (all/Grade 3) were thrombocytopenia 72%/47% (G3 and G4), nausea 72%/6%, anaemia 53%/19% and fatigue 53%/9%, all expected and manageable with supportive care and dose modifications. MTD and RP2D were identified as selinexor 80 mg, carfilzomib 56 mg/m2, and dexamethasone 40 mg, all QW. The overall response rate was 78% including 14 (44%) ≥ very good partial responses. Median progression-free survival was 15 months. Conclusions Weekly XKd is highly effective and well-tolerated. These data support further investigation of XKd in patients with MM.

Objective To evaluate the combination of pembrolizumab, cisplatin and gemcitabine in recurrent platinum-resistant ovarian cancer. Methods Patients received six cycles of chemotherapy with gemcitabine and cisplatin on day 1 and day 8 of a 21-day treatment cycle. Pembrolizumab was administered on day 1 of cycles 3–6 and as maintenance monotherapy in cycles 7–34. Palliative radiation to a non-target symptomatic lesion was allowed. The primary objective was overall response rate by RECIST 1.1 criteria. Secondary objectives included safety, progression-free survival, time to progression, duration of response and overall survival. Results An interim analysis for futility was performed at 18 evaluable patients. Overall response rate was 60%, duration of response was 4.9 months and time to progression was 5.2 months. Progression-free survival at 6 and 12 months was 43% and 5%. Median progression-free survival was 6.2 months and median overall survival was 11.3 months. In all patients, CA125 levels reflected response and progression. There were no pseudoprogression events. After receiving palliative radiation during pembrolizumab maintenance, a patient with recurrent ovarian clear cell carcinoma had an exceptional and durable response that is ongoing for greater than 2 years. After consultation with the sponsor, based on the modest duration of response observed at the interim analysis for futility, the decision was made to close the trial to further accrual. Conclusions The addition of pembrolizumab to cisplatin and gemcitabine did not appear to provide benefit beyond chemotherapy alone in patients with recurrent platinum-resistant ovarian cancer.

Purpose We report the efficacy and safety of dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) combination therapy in BRAF V600E–mutated anaplastic thyroid cancer, a rare, aggressive, and highly lethal malignancy with poor patient outcomes and no systemic therapies with clinical benefit. Methods In this phase II, open-label trial, patients with predefined BRAF V600E–mutated malignancies received dabrafenib 150 mg twice daily and trametinib 2 mg once daily until unacceptable toxicity, disease progression, or death. The primary end point was investigator-assessed overall response rate. Secondary end points included duration of response, progression-free survival, overall survival, and safety. Results Sixteen patients with BRAF V600E–mutated anaplastic thyroid cancer were evaluable (median follow-up, 47 weeks; range, 4 to 120 weeks). All patients had received prior radiation treatment and/or surgery, and six had received prior systemic therapy. The confirmed overall response rate was 69% (11 of 16; 95% CI, 41% to 89%), with seven ongoing responses. Median duration of response, progression-free survival, and overall survival were not reached as a result of a lack of events, with 12-month estimates of 90%, 79%, and 80%, respectively. The safety population was composed of 100 patients who were enrolled with seven rare tumor histologies. Common adverse events were fatigue (38%), pyrexia (37%), and nausea (35%). No new safety signals were detected. Conclusion Dabrafenib plus trametinib is the first regimen demonstrated to have robust clinical activity in BRAF V600E–mutated anaplastic thyroid cancer and was well tolerated. These findings represent a meaningful therapeutic advance for this orphan disease.

The treatment of transplant-eligible multiple myeloma patients in Italy consists in an induction phase based on bortezomib plus thalidomide plus dexamethasone (VTd), followed by a single or tandem autologous stem cell transplantation (ASCT), followed by lenalidomide maintenance. This approach offers an overall response rate of 93% and a CR rate of 58% with acceptable toxicity. Lenalidomide maintenance adds a significant increase in disease control, with a progression free survival after ASCT of 53 months, and an overall survival of 86 months. Second primary malignancies represent the most concerning toxicity of lenalidomide maintenance with a 6.9% incidence. However, the benefit in terms of increased myeloma control largely outweigh this complication. The incorporation of daratumumab in this treatment schema will further improve these clinical results.

Achievement of CR and nCR Before and After First High-Dose Therapy Followed by Autologous Stem Cell Transplantation Is a Major Marker for Long-Term Survival in Multiple Myeloma Patients.

Abstract Abstract 3400 Poster Board III-288 To analyse the impact of complete response (CR), near CR (nCR) and very good partial response (VGPR) before and after first high-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) on overall survival (OS) and progression-free survival (PFS), we evaluated all patients with multiple myeloma (MM) who underwent an ASCT in frontline treatment at our centre. The transplantations were performed between June 1992 and February 2009 giving a minimum follow up of 5 months after ASCT. The retrospective analysis included a total of 994 patients (579 males and 415 females) with a median age of 58 years at time of first ASCT (range 25 - 76 years). Median follow-up after first ASCT was 5.8 years. All patients suffered from symptomatic MM. Before induction treatment 48%, 31% and 21% of patients were in ISS-stage I, II and III, respectively. The following induction regimes were applied prior to HDT: VAD (n=683), TAD (n=74), PAD (n=64), and other regimes (n= 173). The patients were treated with HDT once (n= 460), twice (n=437) or thrice (n=97). 91 patients received an allogeneic SCT, 30 of these before first progression after ASCT. These were censored for PFS at time of allogeneic SCT. Maintenance therapy (interferon n=332, thalidomide n=203, bortezomib n=48 or others n=13) was administered in 596 patients. Overall survival and progression-free survival were calculated from the time of first ASCT. The median OS time was 5.7 years and the median PFS was 2.2 years. Log-rank test, univariate and multivariate Cox PH regression as well as landmark analyses were utilized to assess the prognostic impact of response. We analysed the effect of achievement of CR, of nCR or CR and of VGPR or CR or nCR before and after HDT, respectively. Achieving CR or nCR is a highly significant prognostic factor for PFS and OS before (p<0.001 and p=0.01, respectively) and after first HDT (both p<0.001). The group including VGPR showed superior outcome when assessed after HDT, driven by the effect of CR/nCR. When adjusting for the effect of age, beta-2 microglobulin before ASCT, albumin before ASCT, new drugs before ASCT (thalidomide and bortezomib; yes/no), second ASCT within 9 months (yes/no), maintenance therapy (yes/no), and date of first ASCT, achieving CR or nCR remained a significant prognostic factor (PFS after ASCT: HR=0.66 [0.54;0.80], p<0.001; OS after ASCT: HR=0.65 [0.51;0.83], p=0.001). In addition, we analyzed the effect of duration of response compared to response achievement per se. Patients who sustained their remission (overall response = PR and better) at 3 yrs after first ASCT had a favourable prognosis with respect to OS compared to patients losing remission. Conclusion: In our single-center cohort achieving CR or nCR before and after first HDT is highly prognostic for PFS and OS in MM. Sustained duration of response is also associated with an improved prognosis (3 years landmark analysis). At our centre we recommend that patients not achieving at least an nCR should be treated with a second cycle of HDT. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 1856 Background: Lenalidomide has proven to be a highly effective treatment in relapsed multiple myeloma (MM), particularly when used in combination with dexamethasone. However, over 30% of patients with myeloma have renal insufficiency and as lenalidomide is renally excreted, little information is available about its use in myeloma patients with impaired kidney function. Defining a safe and effective dose of lenalidomide in this context is critical. Objective: We undertook this study to establish the maximum tolerated dose of lenalidomide in three cohorts of patients with different levels of impaired renal function: Group A - patients with creatinine clearance (CrCl) between 30 and 60 mL/min, Group B - patients with CrCl <30 mL/min not on dialysis, and Group C - patients with CrCl < 30mL/min who are on dialysis. Secondary endpoints included response rate, progression free survival and overall survival. Methods: Eligible patients had previously treated MM with renal impairment defined as creatinine clearance < 60 mL/min measured within 21 days prior to registration. Patients previously treated with lenalidomide were required to demonstrate clinical response (any duration) or stable disease with progression-free interval of > 6 months from start of that therapy. All patients received dexamethasone 40 mg orally on days 1, 8, 15 and 22 of a 28-day cycle. Prophylactic anticoagulation consisted of either 81 mg or 325 mg per day of aspirin. Patients also received lenalidomide orally every 1 or 2 days on days 1 through 21 of a 28-day cycle, as described below (Table 1). Starting doses were as in US Product Insert. Dose escalation follows a standard 3+3 design. Results: There have been 23 patients enrolled into groups and cohorts as shown in Table 1. Median age was 73 (range 49–89) and 13 (57%) were women. ISS stage was advanced in all patients, 0 in stage 1, 4 (18%) in stage 2 and 19 (82%) in stage 3. The regimen was well tolerated. Indeed, the MTD has not been reached in any of the groups, as no DLTs have occurred to date. The most commonly reported clinical adverse events (all grades, independent of attribution) across all patients included infections, hyperglycemia, constipation, dizziness, hyponatremia, hypocalcemia and tremor. Hematological toxicities (grade 3–4) occurred in 13 out of 21 pts (62%), mostly neutropenia and thrombocytopenia. Grade 3–4 events at least possibly related to the regimen occurred in 70% and included pneumonia (26%) and otitis media (9%). Response was seen in 14 patients, resulting in an overall response rate of 61%. CR was seen in 1 patient (4%), VGPR in 2 patients (9%), PR in 11 patients (43%), and SD for 9 patients. With median follow-up of 15.5 months, median progression-free survival is 9.8 months and median overall survival is 22 months. Conclusion: Lenalidomide and dexamethasone is a safe and effective regimen in patients with multiple myeloma and renal insufficiency. It is also very well tolerated, although cytopenias are common but manageable. MTD has yet to be reached in each group, allowing for higher doses to be given than previously thought, including 25mg daily (for 21/28 days) in patients with CrCl 30–60 mL/min, 25 mg every other day (for 21/28 days) in patients with CrCl < 30 mL/min not on dialysis, and 10mg daily (for 21/28 days) in patients with CrCl < 30 mL/min on dialysis. These results will provide needed, clinically relevant dosing for lenalidomide in MM patients with renal insufficiency.

PURPOSE Nivolumab 1 mg/kg plus ipilimumab 3 mg/kg (NIVO1+IPI3) is approved for first-line treatment of patients with advanced melanoma in several countries. We conducted a phase IIIb/IV study (CheckMate 511) to determine if nivolumab 3 mg/kg plus ipilimumab 1 mg/kg (NIVO3+IPI1) improves the safety profile of the combination. PATIENTS AND METHODS Patients (N = 360) age 18 years or older with previously untreated, unresectable stage III or IV melanoma were randomly assigned 1:1 to NIVO3+IPI1 or NIVO1+IPI3 once every 3 weeks for four doses. After 6 weeks, all patients received NIVO 480 mg once every 4 weeks until disease progression or unacceptable toxicity. The primary end point was a comparison of the incidence of treatment-related grade 3 to 5 adverse events (AEs) between groups. Secondary end points included descriptive analyses of objective response rate, progression-free survival, and overall survival. The study was not designed to formally demonstrate noninferiority of NIVO3+IPI1 to NIVO1+IPI3 for efficacy end points. RESULTS At a minimum follow-up of 12 months, incidence of treatment-related grade 3 to 5 AEs was 34% with NIVO3+IPI1 versus 48% with NIVO1+IPI3 ( P = .006). In descriptive analyses, objective response rate was 45.6% in the NIVO3+IPI1 group and 50.6% in the NIVO1+IPI3 group, with complete responses in 15.0% and 13.5% of patients, respectively. Median progression-free survival was 9.9 months in the NIVO3+IPI1 group and 8.9 months in the NIVO1+IPI3 group. Median overall survival was not reached in either group. CONCLUSION The CheckMate 511 study met its primary end point, demonstrating a significantly lower incidence of treatment-related grade 3-5 AEs with NIVO3+IPI1 versus NIVO1+IPI3. Descriptive analyses showed that there were no meaningful differences between the groups for any efficacy end point, although longer follow up may help to better characterize efficacy outcomes.

PURPOSE Phosphatidylinositol-3-kinase (PI3K) inhibitors have shown activity in relapsed or refractory (R/R) indolent non-Hodgkin lymphoma (iNHL). PI3K inhibitors have been hampered by poor long-term tolerability and toxicity, which interfere with continuous use. Umbralisib, a dual inhibitor of PI3Kδ/casein kinase-1ε, exhibits improved selectivity for PI3Kδ compared with other PI3K inhibitors. This phase IIb trial was designed to evaluate the efficacy and safety of umbralisib in patients with R/R iNHL. PATIENTS AND METHODS In this multicohort, open-label, phase IIb study, 208 patients with R/R marginal zone, follicular, or small lymphocytic lymphoma (MZL, FL, or SLL) unresponsive to prior treatments (≥ 1 MZL; ≥ 2 FL/SLL), including ≥ 1 anti-CD20–based therapy, were administered umbralisib 800 mg orally once daily until disease progression, unacceptable toxicity, or study withdrawal. Primary end point is overall response rate; secondary end points include time to response, duration of response, progression-free survival, and safety. RESULTS The median follow-up is 27.7 months (efficacy) and 21.4 months (safety). The overall response rate was 47.1%, and tumor reduction occurred in 86.4% of patients. The median time to response was 2.7-4.6 months. The median duration of response was not reached for MZL, 11.1 months for FL, and 18.3 months for SLL. Median progression-free survival was not reached for MZL, 10.6 months for FL, and 20.9 months for SLL. At least one grade ≥ 3 treatment-emergent adverse event (TEAE) was reported in 53.4% of patients. TEAEs led to umbralisib discontinuation in 32 patients (15.4%). A total of 31 patients (14.9%) discontinued because of a treatment-related adverse event. Grade ≥ 3 TEAEs reported in ≥ 10% of patients: neutropenia (11.5%) and diarrhea (10.1%). Increased ALT/AST (grade ≥ 3) occurred in 6.7%/7.2% of patients. CONCLUSION Umbralisib achieved meaningful clinical activity in heavily pretreated patients with iNHL. The safety profile was manageable, with a relatively low incidence of immune-mediated toxicities and adverse event–related discontinuations.
