Abstract Background: IFI remain an important cause of morbidity and mortality in pts with acute myelogenous leukemia or high risk myelodysplastic syndrome (AML/HR-MDS). We have previously shown that voriconazole (VORI) or LIPO AB 3 mg/kg/day TIW were effective prophylactic regimens in AML/HR-MDS. LIPO AB given once every week achieves tissue levels expected to prevent IFI, decreases the risk for infusion-related adverse events (IRE) and would simplify prophylaxis. Materials and Methods: We conducted a 3-arm randomized trial comparing LIPO AB, 3 mg/kg/d TIW (LIPO AB 3); versus LIPO AB 9 mg/kg/d, 1/week (LIPO AB 9); versus VORI 200 mg PO 2/day among pts with AML/MDS undergoing induction or salvage chemotherapy (CHEMO). Pts were stratified by age and disease status and randomized to receive any of the 3 regimens 24 hours after completion of CHEMO. Serum Galactomannan Index (GMI) was obtained 2/week while CT scan of chest (CT) was performed for persistent fever after 3 days of broad spectrum antibiotics. Proven and probable IFI were defined according to EORTC/MSG criteria. The results of the first 59 pts (of 150 planned) enrolled between Dec 06 -July 07 are presented. Results: Pts characteristics and response are shown in Table 1. All pts had Zubrod performance status ≤ 2 and most underwent remission induction chemo (90% in each group). No significant differences were observed on key baseline characteristics. Three of the 59 pts did not receive study drug (AMBI 9=2; VORI=1) and were excluded from efficacy and safety analysis. There were no proven IFI; 3 pts developed probable pulmonary Aspergillosis [GMI(+); CT (+), cultures (−) ], while 10 pts received additional empirical antifungal therapy (AFT) because of FUO [ 7 pts; GMI (−), CT (−), cultures (−)] or pneumonia [ 3 pts; GMI (−), cultures (−)]. None of these 10 pts developed proven/probable IFI. Two pts in each study arm developed reversible side effects that lead to drug discontinuation [AMBI 3: Grade 2 hyperbilirubinemia (1); Grade 3 infusion related events (1); AMBI 9: Grade 3 infusion related event (2); VORI: Grade 2 hyperbilirubinemia (1), visual hallucinations (1)]. Overall mortality was 5% (1 pt/arm). There were no IFI-related deaths. Conclusion: Intermittent LIPO AB (3 mg/kg/d TIW or 9 mg/kg/d, 1/week) and VORI 200 mg PO 2/day prophylaxis appear to be effective and well-tolerated regimens. Enrollment of additional pts is ongoing.

Abstract Background Omadacycline (OMC) is a novel aminomethylcycline with activity against Gram-positive, many Gram-negative, anaerobic, and atypical pathogens. It is in clinical development as once-daily oral (PO) and intravenous (IV) monotherapy for acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia (CABP). Cumulative safety results from Phase 3 clinical trials are reported. Methods This pooled safety analysis is based on 2,150 subjects: OASIS-1 (N = 645), OASIS-2 (N = 735) in ABSSSI; OPTIC (N = 770) in CABP. Comparators were linezolid (LZD) 600 mg IV then PO in ABSSSI (n = 689); moxifloxacin (MOX) 400 mg IV then PO in CABP (n = 388). Safety parameters included treatment-emergent adverse events (TEAEs), laboratory evaluations, vital signs, and electrocardiogram (ECG) findings. Results A total of 1,073 subjects received OMC: 705 received OMC IV then PO (ABSSSI, n = 323; CABP, n = 382); 368 received OMC PO only for ABSSSI. Overall, 60.6% were male and 91.6% white; mean age ranges were 44.7–45.1 and 60.9–62.1 years in ABSSSI and CABP studies, respectively. TEAEs were observed in 47.5% (OMC), 41.2% (LZD), and 48.5% (MOX) of subjects, with gastrointestinal events the most common TEAEs. Serious TEAEs were low (3.6% OMC, 1.9% LZD, 6.7% MOX). Nausea (14.9% OMC, 8.7% LZD, 5.4% MOX) and vomiting (8.3% OMC, 3.9% LZD, 1.5% MOX) were the most frequently reported TEAEs. Diarrhea was observed in 2.4% OMC, 2.9% LZD, and 8.0% MOX subjects, with no cases of Clostridium difficile in OMC-treated subjects. Most TEAEs were mild to moderate and did not result in study drug discontinuation (3.1% OMC, 1.5% LZD, 7.0% MOX); 4 OMC, 1 LZD, and 0 MOX subjects discontinued for nausea and vomiting. Frequency of hepatic TEAEs was similar for OMC, LZD, and MOX: 4.3% OMC, 4.1% LZD, and 4.5% MOX subjects had post-baseline ALT >3× upper limit of normal. Vital signs and ECGs had comparable clinically notable values post-baseline in each treatment group. Known tetracycline class adverse events such as fungal infections were similar in all groups. Conclusion Pooled analyses demonstrate a favorable OMC safety profile, consistent with its tetracycline heritage. OMC was generally well tolerated in subjects with ABSSSI and CABP, with infrequent treatment discontinuations. Disclosures T. M.

Abstract Invasive fungal infections (IFI) are a frequent cause of morbidity and death in pts with AML and high-risk myelodysplastic syndrome (HR-MDS). Because early diagnosis of IFI is difficult, antifungal prophylaxis (AFP) including mold-active agents has become an important strategy to reduce morbidity and mortality in this patient population and is routinely used at MDACC for AML and HR-MDS pts undergoing RIC. We retrospectively compared the efficacy and safety of 6 AFP regimens (Sept 97- July 04) among 659 evaluable pts with newly diagnosed AML and HR-MDS who received RIC and had been enrolled in our prospective AFP trials. See regimens listed in Table below. There were no significant differences among the 6 regimens with regard to key baseline characteristics (age, gender, diagnosis, cytogenetics, type of RIC, Zubrod PS, WBC count, non-fungal infection and protected environment) and median days of AFP. 37 pts (5.6%) developed IFI (yeast 3 %; mold 2.6%). No mold infections were observed among pts randomized to AMBI or VORI. With the exception of VORI, which was significantly more effective than IV ITRA (p =0.03), all comparisons of efficacy among the AFP regimens were not significant. Drug discontinuation was the highest with IV VORI (21%) and ABLC (18%). VORI was more toxic than IV ITRA, Caspo, and F+I (p=0.023, 0.001 and 0.031 respectively). VORI toxicity was reversible and consisted of visual and/or auditory hallucinations and elevation in serum bilirubin. There was a trend toward developing VORI toxicity if baseline bilirubin levels were elevated (OR=4.9; p=0.10). We conclude that the rate of IFI in AML and HR-MDS pts undergoing RIC given mold-active AFP is 5.6 %. VORI and AMBI effectively prevented mold infections. VORI was more effective that IV ITRA but was associated with a high rate of reversible drug-related adverse events.

315 Background: Combination therapy with nivolumab + ipilimumab (NIVO+IPI) has demonstrated long-term efficacy and tolerability for patients (pts) with previously untreated advanced renal cell carcinoma (aRCC). Most pivotal clinical trials in pts with aRCC have excluded pts with low Karnofsky performance status (KPS; < 70%). CheckMate 920 is a multi-arm, phase IIIb/IV, open-label clinical trial of NIVO+IPI treatment in pts enrolled in a community practice setting with aRCC and a high unmet medical need. We present safety and efficacy results for the cohort of pts with aRCC of any histology and KPS 50%–60% from CheckMate 920 (NCT02982954). Methods: Pts with previously untreated advanced/metastatic RCC and KPS 50%–60% received NIVO 3 mg/kg + IPI 1 mg/kg Q3W × 4 doses followed by 480 mg NIVO Q4W for ≤ 2 years or until disease progression/unacceptable toxicity. The primary endpoint was incidence of grade ≥ 3 immune-mediated adverse events (imAEs) within 100 days of last dose of study drug. Key secondary endpoints included progression-free survival (PFS) and objective response rate (ORR) by RECIST v1.1 (both per investigator). Exploratory endpoints included overall survival (OS). Results: Of 25 treated pts with KPS 50%–60%, 76% were men; median age was 67 years (range, 34–81). IMDC risk was favorable in 0%, intermediate in 32%, and poor in 68% of pts; 84% had clear cell and 16% had non-clear cell RCC histology. With a minimum follow-up of 25 months, median duration of therapy (95% CI) was 2.3 months (2.1–7.7) for NIVO and 2.1 months (2.1–2.1) for IPI. The median number of doses (range) received was 4 (1–27) for NIVO and 4 (1–4) for IPI; 76% of pts received ≥ 4 NIVO doses and 68% received all 4 IPI doses. The only grade 3–4 imAEs by category were hepatitis (4.0%) and adrenal insufficiency (4.0%). No grade 5 imAEs occurred. Overall, 4 (16%) pts discontinued due to any-grade adverse events (n = 1 each for elevated AST, malignant neoplasm progression, back pain, and acetabulum fracture). Of 18 evaluable pts, ORR was 33.3% (95% CI, 13.3–59.0); no pts had a complete response and 6 had partial response. Median time to objective response was 4.5 months (range, 2.5–24.7). Median duration of objective response was 20.6 months (range, 0.03+–24.2+). Median PFS was 4.6 months (95% CI, 2.5–14.8). Median OS was 15.6 months (95% CI, 5.3–25.1). Conclusions: NIVO+IPI demonstrated an acceptable safety profile and promising antitumor activity in pts with previously untreated aRCC and KPS 50%–60%. The combination was tolerated at a dose intensity similar to that observed in clinical trials conducted in pts with higher KPS (≥ 70%). These data support the value of NIVO+IPI in pts who may not be considered ideal candidates for this therapy and consequently may have limited treatment options.

e24072 Background: The prophylaxis of neutropenia has been evolving from short acting granulocyte colony-stimulating factors (G-CSFs) to long acting G-CSFs. The safety and effectiveness of long acting G-CSF in a real-world setting were still lacking. Methods: We performed a multi-center, non-interventional, real-world study to explore the tolerability and effectiveness of mecapegfilgrastim. Different prophylactic strategy (primary or secondary prophylaxis) were compared. The effect of mecapegfilgrastim by means of continuous administration was also explored. Results: This study included 638 patients who had complete the study from May 2019 to November 15, 2020. About half of the participants were breast cancer patients. The mean age of the patients were 56 years. The most frequently reported adverse event possibly related to study drug was white blood cell increase (6.2 %). No unexpected adverse events were reported. Overall, thirty-six (5.6 %) patients experienced grade ≥ 3 neutropenia in chemotherapy cycle one. The patients in the primary and secondary prophylaxis subgroups had incidence of grade ≥ 3 neutropenia of 4.3 % and 9.2 % in chemotherapy cycle one respectively. There was a decreasing trend of neutropenia from cycle one to cycle four when mecapegfilgrastim were administrated continuously. Conclusions: The mecapegfilgrastim was well tolerable and no unexpected adverse events were observed in real-world setting. Primary prophylaxis using mecapegfilgrastim had lower incidence of neutropenia than secondary usage.

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 Background: Thalidomide has marked activity in both untreated and heavily pretreated myeloma. Its activity in part is believed to be due to inhibition of bFGF and VEGF induced angiogenesis. Elevated levels of bFGF in serum and urine have correlated with decreased survival in lymphoma possibly through up-regulation of BCL-2. Methods: 25 patients (pts) with previously treated F-NHL and SLL were registered and treated on this multi-institutional study from July 2001–April 2004 to evaluate the efficacy and safety of oral thalidomide in this patient group. Pts had B-cell SLL (7: 36.8%), F-NHL grade 1 (7: 36.8%), grade 2 (3: 15.8%) and grade 3 (2: 10.1%) NHL. Pts were eligible for entry with up to 3 prior chemotherapy (CT) and 2 immunotherapy (IT) regimens provided performance status was ≥ 1. Pts with new onset of B-symptoms, rising LDH, rapid tumor growth or greater than one year from initial diagnosis were required to undergo repeat lymph node biopsy to exclude recent transformation. Pts with CNS involvement, prior peripheral neuropathy >gr 1, HIV+, and pregnant or nursing women were also excluded. Pts were required to have Cr <2 x ULN, AST/ALT <2.5 x ULN and an ANC > 750. Median age at study entry was 60 years (36–87). Prior therapy was evaluated in 20 pts and 17/20 had received multi-agent CT while 12/20 pts received prior IT. Thalidomide was initiated at a dose of 200 mg daily and escalated by 100 mg daily every 1–2 weeks as tolerated with a maximal dose of 800 mg/d. If ≥ gr 2 peripheral neuropathy or ≥ gr 3 somnolence or mood changes occurred, the dose was held for one week and restarted at 50% of the prior daily dosage. Results: The median daily dose was 400 mg (range 50–800 mg). There was 1 complete response (CRu-residual abnormality) in a pt with SLL and one partial response in a pt with F-NHL grade 1 (ORR 8%: 95%CI: 1–26%). 16 pts had progressive disease during therapy and 2 died of disease soon after stopping therapy due to adverse events. One patient continues on therapy without progression of disease to date. The remaining 4 pts were taken off of therapy prior to the first 3 month evaluation. The reason for withdrawal was pt refusal (2) and adverse events (2). The median event free survival was 2.6 months (95% CI:1.4–4.4 mos) with a median overall survival of 23.3 months. Toxicity information on 24/25 pts revealed 4 (17%) with grade 4 neutropenia with 1/4 febrile as well. The most common grade 3 toxicities were anemia (13%), dyspnea (13%), fatigue (8%) and neurologic toxicities consisting of somnolence, dizziness, depression and anxiety (21%). Peripheral sensory neuropathy was reported as gr 2 in 8% and gr 3 in 8%. However, 38% of pts were reported as experiencing gr 2 fatigue. There were no grade 5 toxicities. Conclusion: These phase II trial results in a pretreated pt population demonstrate that, despite an acceptable toxicity profile, thalidomide has only minimal efficacy in F- NHL and SLL.

Abstract OBJECTIVES: With a greater focus on costs in today’s health care markets, it is important to evaluate overall costs and quality of care associated with new therapies in cost-effectiveness analyses. Adverse events (AEs) associated with cancer therapies often result in substantial economic costs and negative impacts on patient quality of life. AEs may also affect adherence to therapy and result in suboptimal treatment outcomes. Important AEs of dasatinib in chronic myelogenous leukemia (CML) patients who are resistant to imatinib include neutropenia, thrombocytopenia, anemia, gastrointestinal hemorrhage, central nervous system hemorrhage, and fluid retention leading to effusions and heart dysfunction. This study evaluated the total cost of treatment with dasatinib in patients with chronic, accelerated, and myeloid blast phase CML, taking into account both drug and AE-associated costs. METHODS: A literature-based economic model was developed to examine the short-term potential impact of AEs in patients with CML treated with dasatinib. The incidence rates of Grade 3/4 AEs were obtained from the SPRYCEL™ (dasatinib) package insert. The AEs were assumed to occur within the first 6 months of treatment. The costs associated with the AEs were obtained from published medical literature and the 2003 Healthcare Cost and Utilization Project database of mean hospital charges by principal diagnosis, converting to costs using a Medicare cost-to-charge ratio of 0.55. Dasatinib dosing assumptions were based on the FDA briefing documents of the SPRYCEL™ filing submission presented at the June 2, 2006 Oncology Drug Advisory Committee meeting. The initial dose for dasatinib was 70 mg twice daily based on the package insert. Patients were assumed to remain on treatment for 6 months. However, dose interruption of 7–14 days during the first 3 months of treatment and dose reduction to 50 mg twice daily in the second 3 months of treatment were assumed in 46–55% and 9–10% of patients, respectively. Drug costs were based on wholesale acquisition cost. Univariate and multivariate sensitivity analyses were conducted. All costs were adjusted to 2006 U.S. dollars using the medical care component of the consumer price index. RESULTS: In the base case analysis, the expected 6-month per-patient cost of treatment for dasatinib was $31,528 for chronic phase, $44,340 for accelerated phase, and $48,666 for myeloid blast phase. Six-month drug cost alone was $22,284 per patient in each phase. Grade 3/4 AEs accounted for approximately 29%, 50%, and 54% of the total cost of care for chronic, accelerated, and myeloid blast phases, respectively. Sensitivity analysis showed that the 6-month cost of Grade 3/4 AEs may range from $5,235–$10,696 for chronic, $16,109–$23,723 for accelerated, and $12,971–$27,551 for myeloid blast phases. Primary cost drivers were the hematologic AEs. CONCLUSIONS: This study provides an estimate for the total cost of treatment with dasatinib that considers treatment costs for severe AEs associated with therapy. These results highlight the importance of including treatment-related AEs in addition to drug costs when assessing the economic value of treatment options for CML. Future studies should expand the time horizon of the analysis and include recurring AEs to more comprehensively evaluate the overall economic impact of AEs with dasatinib.

Aims:To assess the incidence of adverse events (AEs) of special interest, including neutropenia, thrombocytopenia, venous thromboembolism (VTE), peripheral neuropathy (PN), and second primary malignancies (SPMs) in RRMM patients (pts) treated with LEN and other antimyeloma therapies according to current clinical practice. Methods: Pts with RRMM who were commencing LEN treatment were enrolled at the investigator's discretion into a LEN cohort (LEN + dexamethasone, the approved combination for the treatment of RRMM); pts who received ≥ 1 prior therapy and were commencing a non-LEN-based therapy were enrolled into a background cohort (all other treatments, including novel agents). Thromboprophylaxis was per local standard practice. AEs were graded according to National Cancer Institute-Common Terminology Criteria for Adverse Events (version 3). SPMs were defined using Medical Dictionary for Regulatory Activities (MedDRA) terms under the category Neoplasms SOC. Following protocol amendment in 2011, assessments for SPMs were to be conducted up to 36 mos after treatment discontinuation. Results: As of June 2016, 3632 pts across 269 institutions in 17 European countries were included in the safety population. Of those, 59.2% received LEN (n = 2151), 32.7% received bortezomib (BORT; n = 1188), 3.8% received thalidomide (THAL; n = 137), and 4.3% received other therapies (n = 156). The majority of pts had discontinued from treatment (97.9%; n = 3556); of the 2.1% (n = 76) ongoing pts, 66 are treated with LEN, 6 with BORT, 0 with THAL, and 4 with other substances. Baseline characteristics were similar across the cohorts. Median age was 70 yrs (range, 25-95 yrs) and 54.0% were male. Of 2985 pts with available ECOG data, 2865 (96.0%) had good performance status (ECOG score 0-2), and the remaining 4.0% had an ECOG score of 3/4. The median number of prior therapies was 1 (range, 1-6) but was higher in the LEN cohort (2; range, 1-6) than in the BORT (1; range, 1-6) and THAL (1; range, 1-5) cohorts; the proportion of pts with only 1 prior treatment was also lower in the LEN cohort (44.3%), whereas BORT was 70.8% and THAL 56.2%. Overall, 50.7% of pts (n = 1842) had grade 3/4 AEs. Grade 3/4 neutropenia occurred in 17.1%, 3.5%, and 4.4% of pts in the LEN, BORT, and THAL cohorts, respectively, and grade 3/4 thrombocytopenia in 9.2%, 7.3%, and 3.6%. The incidence rate of SPM was 3.63 per 100 pt-yrs, with 3.18 per 100 pt-yrs in the LEN cohort, 5.23 per 100 pt-yrs in the BORT cohort, 2.73 per 100 pt-yrs in THAL, and 6.48 per 100 pt-yrs in others. AEs of interest of all grades are listed in Table 1. The median duration on study treatment was 6.6 mos (range, 0.1-81.6 mos) for LEN, 4.1 mos (range, 0-63.6 mos) for BORT, and 4.6 mos (range, 0.2-36.9 mos) for THAL. Treatment discontinuation rate due to AEs was similar in each cohort (22.1% in the LEN, 20.0% in the BORT, and 21.2% in the THAL cohorts). In the LEN cohort, dose reductions occurred in 38.1% of pts, with a median time to first dose reduction due to AEs of 12.4 weeks. Treatment-emergent adverse events leading to dose reductions were similar across cohorts, with 23.7% in the LEN cohort, 21.4% in the BORT cohort, and 17.5% in the THAL cohort. Conclusions: Results of this noninterventional study in RRMM show that AEs were similar across cohorts except for higher rates of neutropenia and lower rates of PN with LEN compared with THAL or BORT. Higher rates of neutropenia did not translate into increased febrile neutropenia. Infections, independent from neutrophil counts, occurred in all cohorts, but few pts developed serious infections such as pneumonia. VTEs as well as myocardial infarctions were low throughout all cohorts. The occurrence of SPMs was generally low and comparable between cohorts. LEN was generally well tolerated.

1003 Background: Single-agent DOC is commonly used to treat MBC. Axitinib (AG) is a potent TKI of VEGFRs. A phase I lead-in study identified 80 mg/m2 q3wks of DOC in combination with 5 mg BID of AG as the recommended phase 2 dose. The primary objective was to determine whether the time to progression (TTP) of AG+DOC arm is superior to DOC+PL. Methods: Pts with no prior chemotherapy for MBC and =12 mos from adjuvant chemotherapy (aCT), measurable disease, ECOG performance status (PS) of 0–2, and no uncontrolled brain metastases were randomly assigned (2:1) to receive treatment with either DOC+AG or DOC+PL without prophylactic growth factor in cycle 1. Tumor measurements were performed q9wks. Pts were stratified according to estrogen receptor (ER) status, prior aCT and PS (0–1 or 2). Results: A total of 168 pts were randomized. 92 pts had received prior aCT, 27 of whom received a prior taxane. Treatment arms were well balanced for prior adjuvant and taxane therapy. A median of 7 cycles of AG+DOC (range: 1–18) and 7 cycles of DOC+PL (range: 1–23) were administered. The most common non-hematologic adverse events observed in the AG+DOC arm included diarrhea (60%), nausea (53%), alopecia (51%), fatigue (49%), stomatitis (44%) and vomiting (40%). Grade 3/4 adverse events that were increased with AG+DOC vs DOC included febrile neutropenia (16 vs 7%), fatigue (13 vs 5%), stomatitis (13 vs 2%), diarrhea (11 vs 0%) and hypertension (5 vs 2%). Other grade 3/4 hematologic toxicities were similar in both arms. The median TTP (by RECIST) was 8.2 mo with AG+DOC arm and 7 mo with DOC+PL arm with a hazard ratio of 0.73 (prespecified, one-sided p=0.052). The overall response rate (ORR) was 40% for AG+DOC arm and 23% for DOC+PL arm (p=0.038). In a hypothesis-generating subgroup analysis, the median TTP in patients receiving prior aCT was 9.0 mo with AG+DOC arm and 6.3 mo with DOC+PL arm with a hazard ratio of 0.54 (p=0.012). Within this stratum, ORR was 45% for AG+DOC arm and 13% for DOC+PL arm (p=0.003). Conclusions: The anti-angiogenic TKI AG combined with DOC (80 mg/m2 q3wks) as first line therapy for MBC has an acceptable safety profile and promising anti-tumor activity.
