Abstract Bisphosphonates effectively reduce the number of skeletal-related events and relieve metastatic bone pain, improving quality of life in patients with malignant bone disease. However, clinical studies have highlighted that some, but not all intravenous (i.v.) bisphosphonates are associated with an increased risk of renal toxicity. The renal safety of bisphosphonates is particularly important in patients with multiple myeloma or in the elderly, who often have some degree of underlying renal damage and are at high risk of renal failure. In phase III trials, the renal safety profile of i.v. ibandronate was comparable to placebo. This agent may therefore be suitable for use in patients with impaired renal health. The current open-label study assessed the renal safety of ibandronate in elderly patients with multiple myeloma and varying stages of pre-existing renal impairment. Patients with multiple myeloma (creatinine clearance 8–139mL/min) received i.v. ibandronate (6mg, infused over 30 minutes). For each patient, deterioration in renal function was graded at baseline using creatinine clearance (grade 0: ≥80, 1: 50–79, 2: 30–49, 3: <30mL/min). Urinary markers of tubular damage (α-glutathione-S-transferase [α GST] and β-N-acetyl-glucosaminidase [βNAG]) were measured at baseline and at 24 and 72 hours following ibandronate infusion. Follow-up toxicity data was collected over 6 months for a subset of patients (n=6). A total of 29 patients (15 females and 14 males; mean age 71.1 ± 5 years) were included in this study. At baseline, four patients had a normal renal function (grade 0). The remaining 25 patients had varying degrees of renal insufficiency (grade 1: n=6, grade 2, n=8, grade 3: n=11). Mean proteinuria was 1799 ± 2140mg/24 hours. Serum creatinine and levels of urinary markers (α GST and βNAG) remained stable throughout the study. There was a statistically non-significant decrease in βNAG, and a positive correlation between ibandronate elimination and creatinine clearance. In the subset of six patients receiving six additional monthly infusions, ibandronate had no negative impact on renal function. To conclude, in this study of elderly patients with multiple myeloma, ibandronate was well tolerated and did not compromise renal health, despite 86% (25/29) of patients having pre-existing renal insufficiency. This was evidenced by markers of tubular damage and renal function, which remained unchanged throughout the study period. Furthermore, a subset of patients who received repeated ibandronate infusions did not experience renal toxicity. The management of drug-related nephrotoxicity needs special attention in patients with multiple myeloma, and in the elderly. These data suggest that ibandronate may be suitable for use in high risk multiple myeloma patients with pre-existing renal impairment. Further studies in larger groups of patients are warranted.

Abstract Backgound: The clinical course of multiple myeloma is often associated with significant bone related morbidity. This can be modified by the use of bisphosphonates. Studies have shown renal toxicity associated with different bisphosphonates especially following the exposure of zoledronic acid. Published literature suggests renal function deterioration occurs in 8.8–15.2% of patients at recommended dose of 4 mg infused intravenously over 15 minutes. Methods: We retrospectively reviewed the records of all patients with multiple myeloma who received bisphosphonates during the period of January 2002-June 2004 at our institution. 114 patients were analyzed (male/female 63/51; age-median 69;mean 71;range 40–92). 61 (54%) were >70 years of age. They received a total of 1301 doses (mean 11.4) during this period. The type of bisphosphonate used was: zolendronate: 58; pamidronate: 23; pamidronate changed to zolendronate (both) : 33. Patients were categorized to the type and sequence of bisphosphonates [ pamidronate vs. zoledronate and pamidronate followed by zoledronate (both) ], age and sex. Renal dysfunction was defined as an increase in serum creatinine of >0.5 mg/dl over baseline. Results: There were 19 patients (16.7%) who developed renal dysfunction. 15 of the 19 episodes (79%) occurred in the 70 years and older group. The table shows the distribution of patients, type of bisphosphonate and the distribution of patients with renal toxicity. Conclusion: This analysis showed increase in renal dysfunction occurs in all ages with use of bisphosphonates. The elderly may be particularly susceptible to this toxicity. Although we have not analyzed the impact of associated comorbidities (including type of multiple myeloma) leading to renal insufficiency in this study, the elderly patients may need more close monitoring of renal function with the use of bisphosphonates.

Cardiopulmonary bypass is widely believed to be injurious to renal function. The unknown consequences of renal dysfunction with modern techniques of bypass in the elderly caused us to examine creatinine clearance and the excretion of sensitive marker proteins in older adult patients undergoing CABG. Thirty male patients were divided into three groups: group I with an age up to 60 years, group II with an age between 61 and 70 years, inclusive and group III 71 years and over. Serum creatinine and urea, creatinine clearance, and α1-micro-globulin (α1-MG), N-acetyl-β-D-glucosaminidase (NAG), Tamm -Horsfall protein (TH) and immunoglobulin G (IgG) were all measured daily, pre- and postoperatively. Creatinine clearance remained lower in the older patients without significant differences. Raised excretion rates of α1-MG, and IgG were seen after CPB. The increase in α1- MG and NAG during the postoperative period revealed tubular damage in all elderly patients. Measurements of α1-MG, NAG and IgG represent useful supplements to standard clinical tests for recognizing early and differentiated changes in renal function.

Background: Venous ulcers are increasing in prevalence, especially since these are observed more frequently in the elderly, and the number of individuals in this age group is becoming a larger portion of the population. Objective: To determine the healing rate and safety of the Profore™ Extra Four-Layer Bandage System in the management of venous leg ulcers. Methods: In an open-label study, patients aged 18 years or older with venous leg ulcers were treated with a high compression four-layer bandage system in which a hydrocellular dressing was placed in contact with the wound. The combination is designated the “Profore Extra Four-Layer Bandage System.” Follow-up visits took place weekly unless there was heavy exudation from the ulcer or if there was marked edema of the leg at the start of the study requiring reapplication of the bandage system. Results: Fifteen patients were entered into the study (men 8, women 7, mean age 66 years, mean duration of ulcers 1.3 years). Thirteen of the 15 patients completed the study, with two withdrawals. In one patient who withdrew, the ulcer became infected and required treatment with antibiotics. The other termination from the study occurred for reasons unrelated to treatment. The ulcer in this patient healed in 7 weeks. Ten of the 13 patients (77%) who completed the study, and 10 (67%) of 15, who had enrolled experienced complete (100%) healing. Healing of > 80% of the ulcers occurred in 11 of 13 patients (85%) who completed the study and in 12 (80%) of 15 enrolled patients. No patient experienced a study-related adverse event. One patient developed contact dermatitis and was later found to have stasis dermatitis. It is unclear whether the initial event was contact or stasis dermatitis. Conclusion: In this open-label study, a high compression system, using the Profore Extra Four-Layer Bandage with a hydrocellular dressing in contact with the wound, was found to be effective and safe for the treatment of venous leg ulcers.

Abstract INTRODUCTION: Lenalidomide (REVLIMID®; CC-5013) is a novel, orally active immunomodulatory drug under investigation for the treatment of multiple myeloma (MM). Phase 1 dose-escalation studies in patients (pts) with relapsed and refractory MM determined that the maximum tolerated dose (MTD) of lenalidomide was 25 mg/day, based upon myelosuppression encountered beyond 28 days, which was manageable with growth factor support and dose reduction. In a multicenter phase 2 study to determine optimal dose and schedule, 102 pts with relapsed or refractory MM were randomized to receive lenalidomide at either 15 mg bid (n=34) or 30 mg qd (n=68), for 21 days every 4 wks. Both treatment arms showed significant activity with manageable toxicity. An increased incidence of cytopenia was noted in the 15-mg bid group and thus the 30 mg qd schedule was taken forward. METHODS: The objective of this multicenter, phase 2, open-label study (CC-5013-MM-014) was to further evaluate the effectiveness and safety of single-agent lenalidomide administered at a dose of 30 mg qd for 21 days every 28 days (28-day cycle) in pts with relapsed and refractory MM. Eligible patients included those who had received prior thalidomide, bortezomib, or SCT. RESULTS: 222 pts were enrolled into the study. All patients had received at least 2 prior anti-myeloma treatments, including bortezomib (41%), thalidomide (80%), and SCT (44%). Table 1 shows Best Response data, excluding patients in whom responses were not evaluable (n=10). Partial response or better occurred in 25% of patients and SD or better in 71%. Time to Progression was a median of 22.4 wks (range 1.8– 66 wks). The median survival has not been reached (the lower bound of the 95% CI exceeds 15 months). The most common treatment-related AEs (those reported in ≥10% of patients overall) included upper respiratory tract infection, neutropenia and thrombocytopenia. AEs that most frequently led to dose reduction or interruption by percentage of cases were neutropenia (40%), thrombocytopenia (23%), fatigue (5%), and anemia (5%). CONCLUSION: Oral lenalidomide in relapsed and refractory MM patients achieved PR+CR in 25%, stable disease or better in 71%, a median TTP of approximately 6 months and a median survival that has not been reached. Toxicity has been manageable with a very low incidence of DVT and minimal treatment-emergent neuropathy. Table 1.

Abstract Lenalidomide is a novel, orally administered immunomodulatory drug (IMiD) that has single-agent activity against multiple myeloma (MM) and additive effects when combined with dexamethasone. We have previously reported improved response (OR), time to progression (TTP) and overall survival (OS) with lenalidomide-dexamethasone (Len-Dex) compared to dexamethasone-placebo (Dex) based on the results of 2 phase III trials (MM-009, North American, 353 pts; MM-010, Europe, Australia, and Israel, 351 pts). In both trials patients with relapsed or refractory MM not resistant to dexamethasone, were treated with dexamethasone 40 mg daily on days 1–4, 9–12, and 17–20 every 28 days and were randomized to receive either lenalidomide 25 mg daily orally on days 1–21 every 28 days or placebo. Beginning at cycle 5, Dex was reduced to 40 mg daily on days 1–4 only, every 28 days. Patients were also stratified with respect to B2M (≤2.5 vs. > 2.5 mg/mL), prior stem cell transplant (none vs. ≥ 1), and number of prior regimens (1 vs > 1). At a median follow-up from randomization of 17.1 mos (MM-009) and 16.5 mos (MM-010), both studies continue to show significant improvement with Len-Dex compared to Dex in OR (MM-009: 61% vs 20.5%, p<.001; MM-010: 59.1% vs. 24%, p<.001, respectively), TTP (MM-009: 11.1mos vs. 4.7mos, p<.001; MM-010: 11.3mos vs. 4.7mos, p<.001, respectively), and OS (MM-009: 29.6mos vs. 20.5mos, p<.001; MM-010: not estimable vs 20.6mos, p<.001, respectively). Pooled data from both trials demonstrates a significant improvement in duration of response for pts achieving ≥ PR with 122/216 pts (56.5%) who received Len-Dex continuing in remission (med. duration of response not reached but > 68.1 wks) compared to only 22/76 pts (28.9%) treated with dexamethasone alone (med. duration of response 22.1 wks, p<.001). An additional subgroup analysis was performed on pts with impaired creatinine clearance (cr cl). No significant difference in response rate, TTP, or OS was noted for patients with cr cl above or below 50 ml/min who were treated with Len-Dex, but for 16 pts with cr cl <30ml/min, med. TTP and OS was shorter than for those with cr cl >30ml/min, but still significantly higher than for pts treated with Dex. Grade 3–4 thrombocytopenia was significantly higher in pts with impaired renal function (<50ml/min, 13.8%; >50ml/min 4.6%, p<.01; <30ml/min, 18.8%, >30 ml/min, 5.5%, p<.05), but there was no difference for G3–4 neutropenia at either cutoff. Phase I–II evaluation to establish appropriate dosing in pts with cr cl < 30ml/min, particularly with respect to thrombocytopenia is warranted, but should not underscore improved OR, TTP, and OS for pts treated with Len-Dex regardless of creatinine clearance.

Abstract BACKGROUND: Pegylated liposomal doxorubicin (CAELYX®) is a liposomal formulation of doxorubicin sterically stabilized by the grafting of segments of polyethylene glycol (PEG) onto the liposomal surface. Given the demonstrated efficacy of VAD (vincristine and doxorubicin and oral dexamethasone) in Multiple Myeloma (MM) patients and the potential for CAELYX® to extend the duration of bone marrow exposure to therapeutic levels of doxorubicin, a combination regimen of CAELYX®, vincristine, and reduced-dose dexamethasone (DVD) has been actively investigated in MM patients. Studies showed that substituting CAELYX® for doxorubicin in the VAD regimen and reducing the dose of dexamethasone in MM patients improves the safety profile and convenience of the treatment regimen without compromising efficacy. Due to potential differences in metabolism of these patients, safety and efficacy results may vary. Thus, we carried out this study in 82 newly diagnosed MM patients in China, in order to demonstrate the efficacy and safety profiles of DVD. METHODS: Patients (n=82) from 15 sites were recruited in this study. CAELYX® (40mg/m2) was infused intravenously over 60-minutes, administered every 28 days. Vincristine (2.0mg) was administered intravenously on Day 1 of each cycle. Dexamethasone (40 mg) was administered from Day 1- Day 4 of each cycle orally or intravenously. The treatment was repeated every 28 days for 4 cycles. RESULTS: Upon ITT analysis, the overall response rate was approximately 68% (56/82); 11% of the patients achieved complete remission (CR), 40% achieved partial response (PR), 17% achieved minimal response; 15% had stable disease (SD), and 12% o had progressive disease (PD) after the treatment. The cumulative 4-month progression-free survival (PFS) was 88%. The incidence of all the adverse events was 46%. The most common non-hematological toxicities were palmar-plantar erythrodysesthesia (13.4%) and stomatitis (6.1%), respectively. CONCLUSION: Pegylated liposomal doxorubicin, vincristine and reduced dose dexamethasone combination (DVD) regimen is an effective and safe regimen in newly diagnosed multiple myeloma patients in Chinese population.

Abstract Introduction: Programmed cell death-1 (PD-1) signaling suppresses the antigen driven activation of T cells upon interaction with its ligands PD-L1 and PD-L2. The PD-1/PD-L1 axis is thought to mediate the resistance of multiple myeloma to conventional therapy (Tamura 2013; Paiva 2015). Nivolumab, a fully human IgG4 monoclonal PD-1 receptor-blocking antibody, has shown clinical activity in a variety of tumor types. Nivolumab has demonstrated a prolonged receptor binding kinetic lasting >100 days that may lead to an efficacy or toxicity signal in the post-treatment period. We therefore evaluated the response of patients with relapsed or refractory multiple myeloma to additional myeloma therapy received within 3 months of the end of nivolumab administration. Methods: The preliminary results of an open-label study that treated patients with relapsed or refractory multiple myeloma using a dose escalation design (1 mg/kg and 3 mg/kg) of nivolumab administered every 2 weeks have been reported previously (NCT01592370, Lesokhin et al., ASH 2014). Here we will report responses and safety data using standard criteria to the next line of therapy received immediately after nivolumab. Results: 8 patients with multiple myeloma from the original open label study were treated at Memorial Sloan Kettering Cancer Center. The disease characteristics and efficacy results are shown in the table. 1 of 8 patients (12.5%) experienced progression while on therapy manifested by development of an isolated plasmacytoma. The patient received radiation and then resumed and completed 97 weeks of therapy with nivolumab. He is currently off therapy without any evidence of disease at 48 weeks after cessation of nivolumab. 3 of 8 patients (37.5%) achieved a partial response to the next line of treatment after nivolumab. 2 of 8 patients (25%) who were exposed and refractory to immunomodulatory drugs (IMiDs) received single-agent, low-dose lenalidomide as the next line of therapy and achieved stable disease lasting approximately 100 days after cessation of nivolumab followed by disease progression. 1 of 8 patients (12.5%) experienced progressive disease despite the next line of therapy, and 1 of 8 patients (12.5%) received an experimental treatment as the next line of therapy and was therefore not evaluable. No new drug-related adverse events occurred in the 3 months after completing treatment with nivolumab. Overall, 6 out of 8 patients derived clinical benefit from post-nivolumab therapy, an unusually high response rate for this population. Conclusions: In a small cohort of patients with relapsed and refractory multiple myeloma, evaluation of response kinetics after cessation of nivolumab supports the notion that long PD-1 receptor binding kinetics may increase the efficacy of subsequent therapy without added toxicity. Larger studies are needed to confirm and expand our findings. Table.
