Larynx Preservation

e16046 Background: Since the results of the RTOG 9111 trial, cisplatin based chemoradiation (CRT) has been the standard of care for LP in advanced laryngeal SCC. Recently, the role of taxanes in managing head and neck SCC has been studied. In 2002 we reported the interim results of a phase II clinical study designed to test the efficacy of P and C concurrent with RT for organ preservation in advanced L and HP SCC. Here we report the long term survival and LP rates. Methods: Eligible patients had untreated advanced L and HP SCC, stage T3N0 or higher and suitable for radical total laryngectomy. Treatment consisted of weekly P (30 mg/m2) and C (20 mg/m2) concurrent to RT up to 7040 cGy in 180 cGy/day fractions. Response evaluation was performed at 5040 cGy and at 4 weeks after completing RT. Salvage surgery was planned for patients not responding at 5040 cGy, residual tumor at the end of RT or at the time of local recurrence. Neck dissection was planned for clinically positive neck (cN1-3). Results: Between 06/1999 and 10/2001, 48 patients were enrolled in a single institution (35 L; 13 HP), 40 male and 8 female with a 58-year median age (39-74). The majority had T3 (64%) N1-3 (52%) disease and 38% needed tracheostomy prior to treatment. Grade (G) 3 and 4 mucositis was noted in 27% of patients, G 3-4 odynophagia in 50%, G 3-4 radiodermatitis in 35% and G 3-4 leucopenia in 13%, with no treatment related death. Two patients needed salvage surgery, one after 5040 cGy and one after 7040 cGy. The complete response rate to treatment was 95%. At a median follow up of 66 months the LP rate at 2 and 5 years were 88% and 54%, respectively. Recurrence free survival (RFS) was 51% at 2 and 47% at 5 years and overall survival (OS) was 81% and 52% at 2 and 5 years, respectively. Conclusions: The finding of similar LP rate and survival compared to the recent reports of high dose cisplatin CRT and neoadjuvant 3 drug CT followed by CRT in an advanced disease population suggests a role for platinum plus taxane as a radiosensitizer regimen in this scenario with acceptable toxicity, but further evaluation in a direct comparative trial with the standard regimen is needed.

Abstract Background High-dose rifampicin may improve outcomes of tuberculous meningitis (TBM). Little safety or pharmacokinetic (PK) data exist on high-dose rifampicin in HIV co-infection, and no cerebrospinal fluid (CSF) PK data exist from Africa. We hypothesized that high-dose rifampicin would increase serum and CSF concentrations without excess toxicity. Methods In this phase II open-label trial, Ugandan adults with suspected TBM were randomised to standard-of-care control (PO-10, rifampicin 10mg/kg/day), intravenous rifampicin (IV-20, 20mg/kg/day), or high-dose oral rifampicin (PO-35, 35mg/kg/day). We performed PK sampling on day 2 and 14. The primary outcomes were total exposure (AUC0-24), maximum concentration (Cmax), CSF concentration and grade 3-5 adverse events. Results We enrolled 61 adults, 92% were HIV-positive, median CD4 count was 50cells/µL (IQR 46–56). On day 2, geometric mean plasma AUC0-24hr was 42.9h.mg/L with standard-of-care 10mg/kg dosing, 249h.mg/L for IV-20 and 327h.mg/L for PO-35 (P<0.001). In CSF, standard-of-care achieved undetectable rifampicin concentration in 56% of participants and geometric mean AUC0-24hr 0.27mg/L, compared with 1.74mg/L (95%CI 1.2–2.5) for IV-20 and 2.17mg/L (1.6–2.9) for PO-35 regimens (p<0.001). Achieving CSF concentrations above rifampicin minimal inhibitory concentration (MIC) occurred in 11% (2/18) of standard-of-care, 93% (14/15) of IV-20, and 95% (18/19) of PO-35 participants. Higher serum and CSF levels were sustained at day 14. Adverse events did not differ by dose (p=0.34) Conclusion Current international guidelines result in sub-therapeutic CSF rifampicin concentration for 89% of Ugandan TBM patients. High-dose intravenous and oral rifampicin were safe, and respectively resulted in exposures ~6- and ~8-fold higher than standard-of-care, and CSF levels above the MIC

BackgroundThe indoleamine 2,3-dioxygenase (IDO) pathway is a key counter-regulatory mechanism that, in cancer, is exploited by tumors to evade antitumor immunity. Indoximod is a small-molecule IDO pathway inhibitor that reverses the immunosuppressive effects of low tryptophan (Trp) and high kynurenine (Kyn) that result from IDO activity. In this study, indoximod was used in combination with a checkpoint inhibitor (CPI) pembrolizumab for the treatment for advanced melanoma.MethodsPatients with advanced melanoma were enrolled in a single-arm phase II clinical trial evaluating the addition of indoximod to standard of care CPI approved for melanoma. Investigators administered their choice of CPI including pembrolizumab (P), nivolumab (N), or ipilimumab (I). Indoximod was administered continuously (1200 mg orally two times per day), with concurrent CPI dosed per US Food and Drug Administration (FDA)-approved label.ResultsBetween July 2014 and July 2017, 131 patients were enrolled. (P) was used more frequently (n=114, 87%) per investigator’s choice. The efficacy evaluable population consisted of 89 patients from the phase II cohort with non-ocular melanoma who received indoximod combined with (P).The objective response rate (ORR) for the evaluable population was 51% with confirmed complete response of 20% and disease control rate of 70%. Median progression-free survival was 12.4 months (95% CI 6.4 to 24.9). The ORR for Programmed Death-Ligand 1 (PD-L1)-positive patients was 70% compared with 46% for PD-L1-negative patients. The combination was well tolerated, and side effects were similar to what was expected from single agent (P).ConclusionIn this study, the combination of indoximod and (P) was well tolerated and showed antitumor efficacy that is worth further evaluation in selected patients with advanced melanoma.

Abstract Postremission treatment is crucial to prevent relapse in acute myeloid leukemia (AML). High-dose cytarabine delivered every 12 hours on days 1, 3, and 5 (HDAC-135) is the standard of care for younger adult patients with AML. Although this standard has been unsuccessfully challenged by other treatment regimens, including multiagent chemotherapy, the timing of HDAC administration has attracted little attention. Here, we retrospectively compared the safety, efficacy, and health care resource consumption associated with HDAC-135 and another standard, condensed HDAC-123 regimen, as consolidation treatment in younger AML patients in first complete response. This study included 221 patients (median age, 46.6 years; range, 18-60 years). HDAC-123 and HDAC-135 were used in 92 and 129 patients, respectively. Both regimens were associated with similar rates of relapse-free survival, cumulative incidence of relapse, nonrelapse mortality, and overall survival, including in core binding factor AML subgroup in which levels of minimal residual disease reduction were similar in both schedules. Hematological recovery times regarding neutrophils and platelets were significantly shorter in patients receiving HDAC-123, with an average difference of 3 to 4 days for each consolidation cycle. The total duration of hospitalization for the whole postremission program was shorter with HDAC-123 (32 days; interquartile ratio [IQR], 22.0,36.5) compared with HDAC-135 (41 days; IQR, 30.5, 50.0) (P < .0001). In conclusion, the condensed HDAC-123 regimen induced faster hematological recovery and therefore significantly reduced the length of hospital stay without affecting treatment response or outcome in younger AML patients.

Abstract Background: 166Ho-DOTMP is a beta-emitting radiophosphonate that localizes specifically to the bone surfaces and can deliver high dose radiation both to the bone and bone marrow. Follow-up data from 3 clinical trials with STR as conditioning for patients with MM undergoing autologous PBSCT are presented. Methods: In 2 Phase I/II dose-escalation trials, 83 patients received a dose of 166Ho-DOTMP STR calculated to deliver 20, 30, or 40 Gy to the red marrow; 82 pts received melphalan (140 or 200 mg/m2) ± 8 Gy TBI (n=25), followed by PBSCT. As of June, 2004, 77 subjects have been followed for at least 48 months. In a separate Phase II dosimetry trial, 12 patients received two 30 mCi tracer doses of 166Ho-DOTMP STR to determine the reproducibility of biodistribution and pharmacokinetics (PK). All pts received a 25 Gy therapy dose with concurrent IV hydration and continuous bladder irrigation, followed by 200 mg/m2 melphalan and PBSCT. These patients have been followed for at least 18 months. Results: Up to 2.3 Ci/m2, 166Ho-DOTMP STR was given in the Phase I/II trials; 29/83 (35%) patients achieved complete response (CR) and overall response rate (CR + PR) was 64% (7 pts not evaluable). The Kaplan-Meier estimate of median survival is 5.2 years for all 83 patients. In patients who are at least 4 years post transplant who achieved a CR, the survival is 74% (n=27). In patients who achieved less than a CR at least 4 years ago, the survival is 34% (n=44). Dose-related radiation-induced kidney toxicity presented in some patients more than 6 months post-therapy. The dose of 166Ho-DOTMP STR in the Phase II dosimetry trial was 550 to 860 mCi/m2, 166Ho-DOTMP. Currently, 18 months of follow-up reveals no occurrence of hemorrhagic cystitis or > Grade 2 elevated creatinine. A CR rate of 17% with an overall survival of 92%, was observed. In 10 patients who received 166Ho-DOTMP STR 750 mCi/m2 ± 10% in the Phase I/II trial, the CR rate was 40%, and the 4-year survival was 70%. Monitoring for safety and duration of response is ongoing in all 3 trials. Conclusion: Follow-up from the Phase I/II trials confirms that 166Ho-DOTMP STR provides favorable efficacy and safety as part of the conditioning regimen for patients with MM undergoing PBSCT. A Phase III, randomized multicenter study is now open to enrollment, comparing the safety and efficacy of 166Ho-DOTMP STR plus melphalan to melphalan alone as conditioning for PBSCT in subjects with primary refractory MM who have failed to respond to induction therapy, including high-dose dexamethasone, and are within 18 months of diagnosis.

Abstract Abstract 2024 Background: For patients with relapsed or refractory HL, salvage chemotherapy followed by aHSCT is the standard of care. Our group previously reported excellent clinical outcomes with accelerated hyperfractionated TLI followed by high-dose chemotherapy and aHSCT (Ann of Oncol. 16:679, 2007). This strategy has been adopted as the standard at our institution for eligible individuals and we now report long-term outcomes of patients previously reported on the phase I/II clinical trial in addition to those who were subsequently treated as standard of care. Patients and methods: Patients with biopsy confirmed relapsed/refractory classical HL who previously received no more than 20 Gy were eligible. Salvage chemotherapy was chosen by the patient's treating physician. All patients received accelerated hyperfractionated TLI prior to transplantation administered twice daily at 150 cGy, five days/week for 10 days. The morning dose was delivered to all nodal sites including the spleen, and the afternoon dose was delivered to all sites of previous and current disease. The goal was to treat uninvolved nodal sites and spleen to 1500 cGy and sites of current and previous disease to 3000 cGy. Conditioning chemotherapy consisted of high-dose carboplatin, cyclophosphamide, and etoposide. All patients received carboplatin 450 mg/m2 by continuous intravenous infusion (CIV) on days –6 to –4 (total dose = 1350 mg/m2) and cyclophosphamide 60 mg/kg/day over 1 h on days –3 and –2 (total dose = 120 mg/kg). Patients on the phase I portion of the trial received escalating doses of etoposide by CIV from days –6 to –4. Initial dosing levels were 400 mg/m2/day, 450 mg/m2/day, 500 mg/m2/day, 600 mg/m2/day and 700 mg/m2/day. Those treated on the phase II portion of the clinical trial or subsequent to the closing of the trial were treated with etoposide 700 mg/m2/day for a total of 2100 mg/m2. Results: 52 patients with relapsed/refractory HL at Northwestern University were treated with TLI and aHSCT from 1993 to January 2011. One patient was lost to follow-up immediately post-transplant. 51 patients were included in this analysis and had a median follow-up of 47 months (range: 0.07–204 months). Thirty patients were treated on a previously reported prospective phase I/II clinical trial. Most patients had nodular sclerosis histology (n=39, 76%) and more than half had primary induction failure (PIF; n=29). Among patients who achieved a CR with induction, 62% relapsed within one year. The most common salvage regimens were ESHAP and ICE chemotherapy and most had received two lines of chemotherapy prior to aHSCT. Only 21 patients (41%) achieved a complete response (CR) with salvage therapy and in most cases (n=31, 61%), response was determined by functional imaging prior to aHSCT. The 10-year PFS and OS for all patients were 56% and 54%, respectively. Ten-year PFS and OS for patients with PIF was 53%, compared with 63% and 59%, respectively, for those with relapsed disease (p=0.13 and p=0.20, respectively). Patients who had incomplete responses to salvage therapy had a 10-year PFS and OS of 41% and 39%, respectively, compared to 76% and 81%, respectively, for those who achieved a CR (p=0.1 and p=0.056, respectively). Treatment-related mortality within the first 100 days was observed in one patient. Five patients (10%) developed secondary malignancies; three developed MDS (one who had received MOPP induction died with MDS; one had relapsed HL post-aHSCT and died of AML and one is alive with MDS 3+ yrs post-diagnosis). There was one case each of T-cell lymphoma (7 months post-aHSCT) and melanoma. Conclusions: Sequential TLI/chemotherapy conditioning for relapsed/refractory HL for patients with limited or no prior radiotherapy continues to be associated with excellent disease control and long-term survival rates including high-risk populations such as PIF and chemotherapy-resistant disease. Disclosures: No relevant conflicts of interest to declare.

In recent years, the management of metastatic renal cell carcinoma (mRCC) has been revolutionized by the advent of targeted therapies. Multitargeted kinase inhibitors (such as sunitinib, sorafenib, pazopanib, and axitinib), the vascular endothelial growth factor inhibitor bevacizumab, and mammalian target of rapamycin inhibitors (such as everolimus and temsirolimus) have become the standard of care for the palliation of metastatic disease. Unfortunately, cumulative toxicities and the lack of marked benefits have prevented the combined use of most molecularly targeted agents. Selected patients with mRCC benefit from immunotherapy, as subsets of patients can experience long-term disease remission or complete response with high-dose interleukin-2. In order to optimize the value of immunotherapy, improvements in the selection of drugs and combinations with novel immunomodulatory agents must be pursued.

15062 Background: Patients (pts) with newly diagnosed AOC generally receive platinum plus taxane therapy. G represents a new active agent to improve the standard regimen. To investigate the safety of two schedules of induction treatments both followed by triplet PCG we have drafted a phase II study. Methods: 14 pts, suboptimally debulked (FIGO stage IIIc) entered the study. HDC ( AUC 7,5) was administered for 2 courses every 21 days ( arm A) and P ( 80 mg/sqm, d 1,8,15,22) + G ( 2500 mg/sqm, d 1,15) (arm B). Both regimens have been followed by standard triplet P ( 175 mg/sqm, d1) + C ( AUC 5, d1) + G ( 800 mg/sqm, d1,8) every 21 days for a total of 6 courses. Antiemetics, corticoids, antihistaminics and ranitidine have been added. Results: The median age was 57 y (39–68). Histology was serous in 64.3%, mixed 14.3% and other 21.4%. All pts had Grade 3 tumor but one. Seven pts received arm A schedule and 7 arm B both followed by PCG regimen. Worst haematological toxicities ( in term of nadir) observed in all courses for all pts were neutropenia G4 ( 42.8% arm A vs 71.4% arm B), anemia G2 (71.4% arm A vs 57.1% arm B), thrombocytopenia G2 ( 57.1% arm A vs 42.8% arm B). Most common non haematological toxicities were alopecia and mild nausea/vomiting. Mild paresthesias in both regimens were observed. No sepsis or neutropenic fever nor unespected toxicity or treatment-related deaths were observed. 71.4% of pts completed foreseen schedules of treatments. 78.5% of pts received erytropoietin and 28.5% G-CSF support. Conclusions: HDC and weekly PG followed by triplet PCG are feasible and safety regimens in AOC pts ( residual disease > 1 cm). Further phase II-III setting study using these schedules will be conducted. No significant financial relationships to disclose.

9528 Background: Imatinib achieves tumor control in most pts with advanced GIST, but the durability of remissions has not been well described. We now present an updated long-term analysis of a randomized phase II trial first presented in 2001, with a median follow-up of 52 months. Methods: 147 pts with unresectable or metastatic malignant GIST were randomized to treatment with daily dosing of imatinib, 400 or 600 mg po. Results: Two pts (1%) achieved a complete response, 98 (67%) achieved a partial response (PR), and 23 (16%) exhibited stable disease (SD) as their best response. Median time-to-response was 13 weeks (95% CI; 12–23 weeks), but one quarter of pts responded after 23 weeks. No significant response differences were seen between the two dose levels tested. The median duration of response was 27 months, and median overall survival was 58 months. Pts with SD or PR had similar 4-year survival rates (64% versus 62%). KIT and/or PDGFRA mutational analyses were obtained in 87% of patients, and the mutational status was highly significant in predicting outcome. GISTs harboring KIT mutations in exon 11, exon 9, and with no detectable mutations in KIT or PDGFRA demonstrated PR rates of 87%, 48%, and 0%, respectively. The median survival for pts with exon 11 KIT mutations has not yet been reached, and it was 45 months for those with exon 9 mutations. Conclusions: While late progression can be seen in GIST pts treated with imatinib, the majority of pts derive benefit. Survival in those achieving SD parallels those with PRs. Late responses are often seen in pts with initial SD, and responses in general are of lasting duration. In particular, pts with KIT mutations in exon 11 (the most common exon affected) have very high response rates and favorable long term survival. [Table: see text]

8042 Background: High-dose therapy (HDT) followed by autologous stem-cell transplantation (ASCT) is the standard of care in TE NDMM. In the phase 3 CASSIOPEIA study, D-VTd significantly improved stringent complete response (sCR), ≥CR, and minimal residual disease (MRD)-negative rates and reduced the risk of progression/death vs VTd in TE NDMM pts. We assessed SC yield and transplantation results among pts receiving D-VTd vs VTd induction prior to HDT/ASCT in Part 1 of CASSIOPEIA. Methods: In Part 1, TE NDMM pts ages 18-65 y were randomized 1:1 to 4 pre-transplant induction and 2 post-transplant consolidation cycles of DARA + VTd or VTd alone. After induction, pts underwent SC mobilization with cyclophosphamide 3 g/m2 (recommended dose) and GCSF. Peripheral blood SCs were harvested based on response to mobilization. Plerixafor was given if SC collection failed at first attempt and in accordance with institutional practice. Melphalan 200 mg/m2 IV was given as HDT prior to ASCT. Results: A total of 1085 pts were randomized (D-VTd, 543; VTd, 542). Among pts who completed mobilization (D-VTd, 506; VTd, 492), more pts receiving D-VTd vs VTd received plerixafor during mobilization (21.7% vs 7.9%). Pts underwent a median (range) of 2 (1-6) vs 1 (1-4) days of apheresis for D-VTd vs VTd. The median number of CD34+ cells collected was lower for D-VTd vs VTd (6.3×106/kg vs 8.9×106/kg). Nevertheless, a similar percentage of ITT pts receiving D-VTd vs VTd underwent ASCT (90.1% vs 89.3%). The median number of CD34+ cells transplanted for D-VTd vs VTd was 3.3×106/kg vs 4.3×106/kg. Hematopoietic reconstitution rates were high and similar for transplanted pts receiving D-VTd vs VTd (99.8% vs 99.6%). For D-VTd vs VTd, a median (range) of 13.0 (6-54) vs 13.0 (4-43) days was required to achieve sustained ANC > 500 cells/mm3, and a median (range) of 14.0 (2-56) vs 12.0 (1-47) days was required to achieve sustained platelets > 20,000 cells/mm3 without transfusion. Conclusions: SC mobilization and collection was feasible with D-VTd induction. Adding DARA to VTd allowed successful transplantation in pts with TE NDMM. Clinical trial information: NCT02541383.

Abstract Burkitt lymphoma (BL) is common in sub-Saharan Africa (SSA). In high-income countries, BL is highly curable with chemotherapy. However, there are few prospective studies from SSA describing nonpediatric BL and no regional standard of care. Thirty-five participants age 15 years or older with newly diagnosed BL were enrolled in Malawi from 2013 to 2018. Chemotherapy was administered according to institutional guidelines, with concurrent antiretroviral therapy if HIV infected. Median age was 21 years (range, 15-61) and 15 participants (43%) were HIV infected. Twenty-seven participants (77%) had stage III to IV disease, and 19 (54%) had Eastern Cooperative Oncology Group performance status >1. Among HIV-infected participants, median CD4 count was 130 (range, 29-605) and 10 (67%) had suppressed HIV viral load. Four participants (11%) died before receiving chemotherapy. First-line chemotherapy consisted of: cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) (n = 22 [71%]); infusional etoposide, prednisolone, vincristine, cyclophosphamide, and doxorubicin (n = 4 [13%]); high-dose methotrexate-based chemotherapy (n = 4 [13%]); and rituximab plus CHOP (n = 1 [3%]). Among 28 evaluable participants, 14 (50%) achieved a complete response. Median overall survival (OS) was 7 months; 1-year OS was 40% (95% confidence interval [CI], 24%-56%). Sixteen (73%) of 22 deaths were a result of disease progression. Compared with CHOP, more intensive chemotherapy was associated with decreased mortality (hazard ratio, 0.24; 95% CI, 0.05-1.02; P = .05). This is among the best characterized prospective cohorts of nonpediatric BL in SSA. Most deaths resulted from progressive BL. Patients who received more intensive therapy seemed to have better outcomes. Defining optimal approaches is an urgent priority in SSA.
