Safety And Efficacy

Abstract Oral mucositis (OM) is a commonly occurring side effect in patients (pts) undergoing AHSCT. Velafermin, recombinant human fibroblast growth factor-20, is under investigation for the prevention of severe OM. Previous studies demonstrated that velafermin at 30 mcg/kg was well tolerated and was effective in reducing the incidence of severe mucositis. The primary objective of this multicenter, randomized, double-blind, placebo controlled study was to confirm safety and efficacy of 30 mcg/kg velafermin for prevention of severe OM incidence (grade 3/4 OM based on the WHO grading system). The secondary objective was to evaluate safety and efficacy of 10 and 60 mcg/kg doses to better define the therapeutic range. Pts were randomized to receive placebo or velafermin at 30, 10 or 60 mcg/kg in a 3:3:1:1 ratio 24–36 hrs after stem cell infusion. Randomization was stratified by study center and OM risk factors identified from the previous placebo controlled study in a similar population including conditioning regimen and body mass index (BMI ≥30). Pts with multiple myeloma or lymphoma (≥18 y.o.) receiving ≥2X106 /kg CD34+ cells following chemotherapy with or without Total Body Irradiation (TBI) were eligible. OM status and safety data were collected for 30 days post treatment while mortality and disease progression were followed for 1 yr. An interim analysis by a data monitoring committee (DMC) was planned to assess safety and efficacy after 50% of pts completed the 30 day treatment period. A total of 390 pts who received melphalan (200 mg/m2) (n=239), BEAM (n=129), TBI (n=15), or other (n=7) were randomized and 384 pts were treated. The study drug was well tolerated in general and no pts discontinued study due to drug-related adverse events. There were 93 serious adverse events (SAEs) in 78 (20%) pts and no drug-related death was reported. Five infusion-related SAEs were reported including vasovagal episode (2), syncope (2), and anaphylactoid reaction (1). All 5 episodes occurred on the day of study drug infusion and resolved on the same day with no sequelae. Based on review of the results from the interim analysis, which included safety and efficacy data from 200 pts, the DMC recommended that the study continue to completion as planned. The last pt has completed the 30 day study period. The un-blinded results of the OM efficacy endpoints from velafermin treated groups or placebo as well as 30-day safety information from all pts will be reported.

6537 Background: Oral mucositis (OM) is a commonly occurring side effect of high-dose chemotherapy (HDCT) in patients (pts) undergoing autologous hematopoietic stem cell transplant (AHSCT). Velafermin, recombinant human fibroblast growth factor 20, is being investigated for prevention of OM. Velafermin promotes epithelial and mesenchymal cell proliferation in vitro and in vivo. Methods: A phase II trial was conducted to evaluate safety, efficacy, and pharmacokinetics (PK) of velafermin. Inclusion criteria: pts undergoing HDCT and AHSCT with or without total body irradiation (TBI) were enrolled. Velafermin at 0.03, 0.1, or 0.2 mg/kg or placebo was administered as single dose IV at 24h after stem cell infusion. Safety and PK were assessed. Pts were scored daily for presence of OM using the WHO grading scale. The primary endpoint was the incidence of Grade 3/4 OM. Results: A total of 212 pts were randomized to either placebo (n=51) or velafermin at 0.03 (n=50), 0.1 (n=56), or 0.2 (n=55) mg/kg (intent-to-treat or ITT sample). 206 pts (97%) received study drug or placebo. Pt diagnoses included multiple myeloma (57%), non-Hodgkin’s (25%), or Hodgkin’s (11%) lymphoma and 13 pts (6%) received TBI as part of the conditioning regimen. The Grade 3/4 OM incidence rates (%) in the placebo or velafermin arms (0.03, 0.1, and 0.2 mg/kg) were 37, 18, 38, and 36, respectively. The primary analysis of dose dependent reduction of severe OM was not statistically significant (p = 0.549). However, velafermin at 0.03 mg/kg did reduce the incidence of Grade 3/4 OM when compared to placebo alone (p = 0.031). Duration of Grade 3/4 OM was reduced significantly in the 0.03 mg/kg when every pt was evaluated or in the 0.1 mg/kg dose when only pts with Grade 3/4 OM were included in the analysis (p = 0.037 and 0.014, respectively). A total of 5 related SAEs (3 in 0.1 mg/kg, 1 in 0.03 mg/kg, and 1 in placebo cohort) occurred within 4hr of study drug infusion. All symptoms were transient. Conclusion: Single dose velafermin at 0.03mg/kg is may be active in reducing CT induced severe OM in AHSCT pts. Safety profile supports continuing study to define the optimal dose for prevention of severe OM. A new Phase II study will be conducted to confirm velafermin activity at 0.03mg/kg dose.

ABSTRACT The combination of liposomal amphotericin B (LAMB) and caspofungin (CAS) holds promise to improve the outcome of opportunistic invasive mycoses with poor prognosis. Little is known, however, about the safety and pharmacokinetics of the combination in patients at high risk for these infections. The safety and pharmacokinetics of the combination of LAMB and CAS were investigated in a risk-stratified, randomized, multicenter phase II clinical trial in 55 adult allogeneic hematopoietic stem cell recipients (aHSCT) with granulocytopenia and refractory fever. The patients received either CAS (50 mg/day; day 1, 70 mg), LAMB (3 mg/kg of body weight/day), or the combination of both (CASLAMB) until defervescence and granulocyte recovery. Safety, development of invasive fungal infections, and survival were assessed through day 14 after the end of therapy. Pharmacokinetic sampling and analysis were performed on days 1 and 4. All three regimens were well tolerated. Premature study drug discontinuations due to grade III/IV adverse events occurred in 1/18, 2/20, and 0/17 patients randomized to CAS, LAMB, and CASLAMB, respectively. Adverse events not leading to study drug discontinuation were frequent but similar across cohorts, except for a higher frequency of hypokalemia with CASLAMB (P < 0.05). Drug exposures were similar for patients receiving combination therapy and those randomized to monotherapy. There was no apparent difference in the occurrence of proven/probable invasive fungal infections and survival through day 14 after the end of therapy. CASLAMB combination therapy in immunocompromised aHSCT patients was as safe as monotherapy with CAS or LAMB and had similar plasma pharmacokinetics, lending support to further investigations of the combination in the management of patients with invasive opportunistic mycoses.

Abstract Mucositis is a painful side effect of many transplant conditioning regimens used in HDC and PBSCT. This complication often requires treatment with potent narcotic analgesics and may even require intravenous patient-controlled analgesia (PCA) for adequate pain relief as well as total parenteral nutrition (TPN). Infections in this setting may also result from disruption of the mucosal barrier with subsequent migration of intestinal bacteria into the blood stream. Previous treatments with oral rinses and topical applications of soothing gels have largely been ineffective. Recently, a breakthrough class of drugs in the fibroblast growth factor (FGF) family holds great promise in more effectively ameliorating or even preventing oral mucositis (OM). We report on the results of a Phase I trial with CG53135-05, a novel investigational protein therapeutic (FGF-20) that promotes epithelial and mesenchymal cell proliferation in vitro and has demonstrated activity in animal models. 14 patients (ages 25–75) undergoing HDCT with PBSCT were treated with escalating doses of study drug, including 0.1 mg/kg, 0.2 mg/kg and 0.33 mg/kg (concentrations are determined by the UV method which are equivalent to 0.3, 0.6, and 1 mg/kg by the Bradford method previously used). Conditioning regimens used included melphalan (Mel 200), cyclophosphamide, carmustine and etoposide (CBV), carboplatin and thiotepa (CT), cyclophosphamide, etoposide and carmustine (CEC) and busulfan/cyclophosphamide (targeted BuCy). The primary objective of this phase I trial was to evaluate safety, tolerability and pharmacokinetics of CG53135-05. Patients (pts.) were also scored daily for presence of OM using both the WHO and OMAS (oral mucositis assessment scale) grading scales. 7/14 pts. in this study experienced no OM (including 2 Mel 200 patients), 5 pts. experienced only grade 1 OM. while 2 pts. (both treated with Mel 200) experienced grade 3 OM, and no pts. experienced grade 4 OM. 1 pt. experiencing grade 3 OM required TPN. Only 4 pts. experienced diarrhea that lasted more than 4 days and only 1 pt. had gut mucositis-associated (E. coli) bacteremia. The median day of engraftment (ANC&gt;500/uL) occurred on day 14 (range: day 11–19). Patients tolerated the study drug well with no significant side effects up to a dose of 0.33 mg/kg. At that dose, 2 pts. experienced an infusional reaction consisting of fevers, nausea, and mild hypotension. Pharmacokinetics were measured at all dose levels and will be presented. CG53135-05 is a member of a breakthtrough drug class (FGF family) that was well tolerated in autologous stem cell transplant patients at doses up to 0.33 mg/kg with apparent clinical effects in ameliorating or preventing OM - 12/14 pts, thus, avoided severe (grades 3–4) mucositis following HDCT. A larger Phase II clinical trial is planned.

Abstract Cytomegalovirus (CMV) disease can be effectively prevented in allogeneic hematopoietic stem cell transplant (HSCT) patients by ganciclovir (GCV) given as prophylaxis or preemptive therapy. Due to the low bioavailability of oral GCV capsules, GCV is usually administered intravenously (IV) to HSCT patients. Valganciclovir (VGCV) is the valine ester prodrug of ganciclovir. In healthy subjects, HIV-infected patients, and solid-organ transplants, the oral bioavailability of VGCV is about 60%, or 10-fold higher than oral GCV capsules. The bioavailability and total GCV exposure provided by oral VGCV relative to IV GCV in HSCT patients with gastrointestinal (GI) GHVD has not been established. METHODS: HSCT patients were eligible for the study if the following criteria were satisfied: 1) ≥16 years of age; 2) biopsy-proven GHVD of GI tract with nausea and/or diarrhea (300–1500 ml/day) or proven GVHD of skin or liver plus diarrhea with no other explanation; 3) no active CMV infection or disease; 4) neutrophil count ≥1000/μL; 5)creatinine clearance >60 ml/min. Following a standardized breakfast, eligible patients were randomized to receive a single dose of open-label study drug (900 mg of oral VGCV or 5 mg/kg of IV GCV). After a minimum 48 hr. washout period, patients were crossovered to alternate study drug. Blood for levels of GCV and VGCV were obtained predose and then over the 24 hours after dosing. Pharmacokinetic (PK) parameters were derived by noncompartmental methods. RESULTS: Data from 16 patients are currently available. Patient demographics include mean age 45 yrs (range 23 to 58 yrs); males 13, females 3; mean weight 80kg (range 52 to 107 kg); mean creatinine clearance 96 ml/min (range 62 to 184 ml/min). Median time after transplant for study was 303 days (range 102 to 988 days). Mean GCV PK parameters are summarized in the following table. Mean GCV Value (Coefficient of variation in %) Oral VGCV-900 mg IV GCV-5mg/kg Parameter N = 16 N = 16 AUC o -τ (μg•hr/mL) 43.58 (37) 46.74 (40) AUC o-∞ (μg•hr/mL) 46.03 (41) 48.89 (43) C(max) μg/mL) ( 6.45 (30) 12.53 (30) T max (hr) 3.13 (22) 0.97 (8) T½ (hr) 4.97 (31) 5.09 (29) GCV AUC values were similar, although maximum GCV concentrations were higher and acheived earlier with IV GCV. Terminal elimination half-life of GCV with oral VGCV and IV GCV were similar. After 900 mg of oral VGCV, mean plasma Cmax for VGCV was low (0.22 μg/mL), which is consistent with rapid and almost complete metabolism of VGCV to GCV. CONCLUSION: These preliminary results suggest that systemic exposure to GCV after 900 mg of oral VGCV is comparable to that achieved with IV GCV in HSCT patients with stable GI GVHD. Oral VGCV could be a useful alternative to IV GCV in certain HSCT patients requiring prophylaxis or preemptive therapy for CMV.

Abstract Background: Chemotherapeutic agents can cause severe oral and gastrointestinal mucositis, for which there is currently no treatment. Previous research demonstrates that palifermin - keratinocyte growth factor - is potentially antimucotoxic, reducing the duration and severity of oral mucositis after intense chemotherapy in hematological cancers. The primary aim of this study was to determine palifermin effectiveness in ameliorating chemotherapy-induced diarrhoea and oral mucositis incidence. Palifermin adverse events were also assessed. Methods: Retrospective observational study involving patients with hematological malignancies undergoing autologous hematopoietic stem-cell transplantation after myelotoxic therapy. All the patients received antibiotic, antifungal, and antiviral prophylaxis. Patients being treated with palifermin to decrease the incidence and duration of severe oral mucositis (Palifermin Group) were compared to a control group of patients who did not receive palifermin (Control Group). Palifermin was administered during 3 consecutive days, before and after myelotoxic therapy in a 60 μg/Kg daily intravenous dose. Results: Twenty-four patients were included, 8 in Palifermin Group and 16 in Control Group. Baseline malignancies were Hodgkin and non Hodgkin lymphoma, acute myeloid leukemia, and multiple myeloma. All patients underwent autologous hematopoietic stem-cell transplantation after the following conditioning regimes: BEAM, BuCy, and Mel200 respectively. In Palifermin Group, 62.5% were male, mean age 47.6±13.0 years, mean disease duration of 22.3±10.1 months (N=8). In Control Group 56.3% were male, mean age 45.8±12.1 years (N=16). Mean performance status (Karnofsky Index) was 80±14.1% and 71.3±15.1%, in each group, respectively. No statistically significant differences between Palifermin and Control Groups were found regarding the degree of diarrhoea, although in the Palifermin Group the majority of patients presented a grade 2 (N=3) and in the Control Group a grade 3 (N=6). In the Palifermin Group there was a tendency for a lower incidence of hypoalbuminemia [12.5% (Palifermin Group) vs. 50% (Control Group)], which corresponded to a significant lower difference in the needs for receiving parenteral nutrition (P=0.011). Nevertheless, these findings were not translated in less febrile episodes or less iv antibiotic therapy days. There were no significant differences between the two groups regarding the degree of oral mucositis, the number of days of analgesic opioids use, and the number of hospitalization days, most probably due to the small sample considered. The most common adverse events in the Palifermin Group were reversible erythema and edema of the face and upper trunk that have occurred only in 3 patients. Weight increase was mild and similar in both groups of patients [Median weight increase±SD: 1,0±1,7 Kg (Palifermin Group) vs 2,0±2,5 Kg (Control group)]. Conclusion: Gastrointestinal and oral mucositis are common consequences of cancer therapy with a direct and significant impact on the quality of life and care costs, also affecting patient’s survival. Our exploratory study shows that palifermin treatment is well tolerated, potentially reducing diarrhoea and the incidence of hypoalbuminemia, and significantly reducing the needs for parenteral nutrition. However further studies with an increased number of patients will be necessary to provide more evidence concerning palifermin efficacy in the management of these cancer therapy’s debilitating side-effects.

e19516 Background: Autologous stem cell transplantation (ASCT) followed by maintenance therapy is the standard of care for transplant-eligible patients with newly diagnosed multiple myeloma. Maintenance typically consists of lenalidomide (LEN), however, bortezomib (BOR) and bortezomib-lenalidomide combination are other options. The respective toxicity of these regimens has not been well studied. We performed secondary data analysis to compare incidence of serious adverse events associated with each maintenance therapy group during post-ASCT maintenance treatment period. Methods: Data was extracted from the open-access MMRF Researcher Gateway corresponding with interim analysis from the CoMMpass study. We extracted data of first-time autologous stem cell transplant patients who completed maintenance therapy post-ASCT. We categorized patients into three sub groups bortezomib, lenalidomide or combination (bortezomib and lenalidomide) maintenance therapy. Incidence rate for serious adverse events (grade 3 or higher) was calculated by number of events per 100 person-months for each maintenance therapy. Results: 231 patients were eligible for our analysis. 169 patients received lenalidomide, 27 bortezomib and 35 combination. The most common adverse event was neutropenia and second most common is pneumonia. Neutropenia incidence was 1.1,0.7 and 0.9 per 100 person-months in lenalidomide, bortezomib and combination regimens respectively. Incidence of deep vein thrombosis, GI intolerance and peripheral neuropathy 0.1 per 100 person-months respectively was observed in lenalidomide group only. Combination maintenance had the highest total adverse event incidence rate of 5.4 per 100 person-months. Incidence of 1.7 and 3.8 per 100 person-months is observed in bortezomib and lenalidomide cohorts respectively. Conclusions: Lenalidomide and bortezomib maintenance had similar incidence of serious adverse events. A higher incidence of serious adverse events was noted in the combination lenalidomide/bortezomib regimens. Interestingly, we observed lower incidence of adverse events in all groups in CoMMpass study compared to respective clinical trials involving maintenance regimens. This may be due to under reporting of adverse events in CoMMpass study. The incidence of adverse events mentioned above should be interpreted in the context of drugs and other factors involved in the disease.
