Nontransplant Treatment Outcomes with Generic Novel Agents in Newly Diagnosed Multiple Myeloma Patients

Abstract Introduction Introduction of novel agents (Immunomodulators-thalidomide/lenalidomide and proteasome inhibitors-bortezomib) has really changed the treatment outcomes in myeloma patients. This is applicable to patients both eligible and ineligible for autologous stem cell transplant. In developing countries, like India, access to the generic forms makes it easy for patients to have treatment with all types of novel agents. In this study, we did a retrospective audit of the treatment outcomes with the generic forms of novel agents in a group of transplant ineligible patients. Methodology All newly diagnosed myeloma cases from January 2011 to December 2014, who did not undergo stem cell transplant, were included for the study. Criteria for diagnosis and treatment response were according to the latest IMWG guidelines. Baseline demographic data and details regarding CRAB criteria, Performance Status (PS), comorbidities, type and duration of treatment, and toxicity were recorded. Toxicity was graded according to CTCAE v 4. Only the maximum grade of a particular toxicity per patient has been reported. Dates of death if applicable was noted, and if patients were alive, date of last follow up was documented. Survival was analysed by non-parametric methods (Kaplan Meier and Cox proportional hazard model) and the variables considered were 'treatment completed' versus 'not completed', 'response' (PR or more) versus 'no response', 'maintenance received' versus 'not received', 'age ≤65 years' versus 'age >65 years', and international staging system (ISS) ' stage 1' versus 'stage 2 or 3'. Analysis was performed with R v 3.2.0 (http://cran.r-project.org.) Results One hundred and nineteen patients (53 males, 66 females) with median age of 62 years (range 44-85) were included as per eligibility criteria. Eighty four (70%) patients had IgG, and 21 (17.6%) had IgA, and 14 (11.7%) had light chain myeloma. Twenty two (18.4%) patients were in ISS stage 1, 36 (30%) were in stage 2 and 39 (32.7%) were in stage 3, with data missing in 22 patients. Fifty seven (47.9%) patients were having comorbidity. Ninety seven patients (81%) were having PS ≤ 2 and 21(17.6%) had PS >2. Lenalidomide based regimen was given in 29 patients, thalidomide based in 65 and bortezomib based in 25 patients. Overall response (PR or more) was documented in 74 (72%), out of 102 evaluable patients. VGPR or more was documented in 56 (55%), and PR in 18(17.6%) patients. Seventy three (61%) patients had some form of toxicity. Grade 3 nonhematologic toxicity occurred in 7 patients (peripheral neuropathy in 2, diarrhea in 2 and DVT in 3), grade 4 in none. Grade 3-4 hematologic toxicity occurred in 8 patients (grade 3 anemia and thrombocytopenia in 3 each, and grade 4 thrombocytopenia in 2 patients). Median follow up duration was 22 months. Estimated 3 year OS for entire group was 60% (95 % CI 47-77%) (Figure 1). Median PFS was 22 months (95 % CI 19- 25) (Figure 2). Variables significantly predicting OS were, treatment completed or not (47 Vs 32 months, HR= 0.372, P= 0.011) and age ≤ 65 versus age >65(47 Vs 31 months, HR= 4.15, P<0.001). Similarly for PFS the significant variables were response or not (24 Vs 7 months, HR= 4.89, P<0.001) and ISS stage 1 Vs stage 2 or 3 (25 Vs 19 months, HR=2.39, P=0.021). Conclusion Treatment with the generic forms of novel agents leads to comparable response rates and survival in patients with myeloma. So, use of these agents with lower cost seems justifiable in the real world practice where it may be difficult to access the innovators for the exuberant cost. Figure 1.

Abstract Abstract 4554 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma, resulting in improved survival and response rate compared to conventional chemotherapy. Disease relapse, however, remains almost inevitable and thus the role of two successive (tandem) autologous stem cell transplants has been evaluated in chemorefractory patients as a means of prolonging duration of disease response. We retrospectively analysed the results of nine patients with chemorefractory disease treated at a single UK institution who received tandem ASCT between January 1998 and February 2009. There were six men and three women. Median age at diagnosis was 56 years (range, 42–65 years). Paraprotein isotype was IgG in eight patients and IgA in one patient. Median serum paraprotein level was 41g/L (range 12–73g/L) at presentation. At time of 1st transplant six patients were in stable disease (SD) and three had evidence of progressive disease. Conditioning melphalan dose was 140mg/m2 in all but two patients who received 110mg/m2 and 200mg/m2. Median time between transplants was 3.7 months (range 2.3–6.4 months) with PR and SD being observed in 2/9 and 7/9 patients at time of 2nd transplant. None of the patients reached complete response (CR). One patient received melphalan 140mg/m2 prior to 2nd transplant. The remaining patients received melphalan 200mg/m2. Median follow up after tandem transplant was 54.3 months (range 15.6 –143.6 months). No treatment related mortality was reported. At the time of analysis, six patients were still alive and under follow up with an overall survival (OS) figure for the group of 52% at 10 years from diagnosis (Figure 1). Median progression free survival (PFS) was 20 months from 2nd transplant (range 6.7–62.6 months) (Figure 2). Tandem autologous stem cell transplant in chemorefractory patients has resulted in overall survival similar to autologous stem cell transplant in chemosensitive patients and should be considered in patients with chemorefractory disease.

Abstract Abstract 1878 Poster Board I-900 Autologous stem cell transplant as a platform for multiple myeloma treatment is the standard of care for patients who can safely withstand the procedure. Before novel agents were introduced, one-third to one-half of patients did not achieve partial response at transplant. Previously published medical literature has showed that in this past era, absence of initial response to induction therapy had no impact on progression-free survival and overall survival after high-dose therapy. Lack of response to initial induction did not preclude a good response after stem cell transplant. With the introduction of novel agents—immunomodulatory drugs and proteasome inhibitors—response rates with initial therapy are now between 70% and 100%. This retrospective study analyzes progression-free survival and overall survival in patients who do not have a partial response after induction therapy with a regimen that contains a novel agent. Unlike patients in reports published previously—before novel agents—patients who do not achieve partial remission have a significantly shorter overall survival from transplant (74.0 vs 43.5 months) and a shorter progression-free survival (22.6 vs 13.1 months; P<.001). Absence of a response to induction therapy with a novel agent predicts a poorer outcome after high-dose therapy.{abstabft}.b CR+VGPR for plateau, P<.001 compared with other 3 categories.

The Impact

Abstract Abstract 4111 In multiple myeloma (MM), the impact of complete response (CR) and very good partial response (VGPR) achievement has been shown mostly after introduction of high dose therapy (HDT) supported by autologous stem cell transplant (ASCT). Recently, the IFM group reported the impact of achievement of CR and VGPR in double ASCT. The purpose of this study is to confirm the prognostic value of CR/VGPR in a large group of patients treated with single ASCT. Methods All consecutive patients who underwent single ASCT at Princess Margaret Hospital between January 2000 and December 2007 were evaluated. Patients were mobilized with cyclophosphamide and G-CSF and majority were conditioned with melphalan 200mg/m2. Response to therapy was assessed according to the IMWC including VGPR. Progression Free Survival (PFS) and Overall Survival (OS) were measured from transplant date to the date of death or last follow-up. OS and DFS were analyzed using the Kaplan-Meier Method. The Cox proportional hazard model was used to assess CR and VGPR and some other prognostic markers at presentation such as age, B2Mg> 460 μmol/L, LDH> 350 IU/L, CRP> 20mg/L, albumin<35g/L and creatinine > 200 μmol/L. All p-values were 2-sided and statistically significant if <0.05. Results 788 patients were identified for the study; their median age was 56 years (30–73). Patient's characteristics are listed in Table 1. Response was assessed at day 100 after ASCT and showed a CR of 6%, PR of 37.5%, and VGPR of 53% (Overall Response rate of 95.5%). Median OS and PFS for the group were 77.43 months and 20.63 months respectively. The median OS and PFS were significantly better for patients who achieved CR/VGPR, 104.5 months versus 51.7 months, and 26.3 months versus 13.53 months respectively. With a median follow-up of 44 months there is no significant difference in OS for those patients who achieved VGPR/CR after induction therapy with novel agents. However, PFS is better in those patients receiving novel agents who achieved VGPR/CR (Median PFS of 24.63months versus 12.4 months respectively (p=0.01). Multivariate analysis shows CR/VGPR as an independent prognostic factor for OS and PFS (Fig 1 and 2). B2Mg> 460 μmol/L, LDH> 350 IU/L, CRP > 20mg/L, albumin<35g/L and creatinine > 200 μmol/L failed to be important factor for survival in the multivariate analysis. Our data suggests that VGPR/CR is clearly important in the pre-novel agents era and for the smaller group of patients who had novel agents induction there is a benefit in PFS and with a longer follow-up perhaps in OS. In conclusion, VGPR/CR remains a simple and powerful indicator in the context of single ASCT and should be considered a relevant objective for MM treatment. Table 1.

Abstract Background The combination of clarithromycin (biaxin), lenalidomide and dexamethasone (BiRd) has been previously shown by Niesvizky, R., et al as a very effective regimen in newly diagnosed myeloma (MM) with an overall response rate of 90.3% and a very good partial response (VGPR) rate of 73.6%. Long term follow up has shown a median progression free survival of 49 months. In a case control comparison, Gay, F., et al showed that BiRd has superior outcomes compared to lenalidomide and dexamethasone (Rd). Clarithromycin appears to optimize the pharmacologic effect of glucocorticoids by increasing the area under the curve and the maximum concentration levels of certain corticosteroids. Clarithromycin has immunomodulatory properties, partially mediated by the suppression of interleukin-6 and other inflammatory cytokines and may also have direct antineoplastic effects. Although the efficacy of BiRd in the frontline treatment of MM is well established, the effect of BiRd in patients who are refractory to Rd is unknown. Methods As part of an IRB-approved study we performed a retrospective analysis on all patients with MM in whom clarithromycin was added to Rd at the time of progression on Rd between January 2007 and March 2013. High risk MM was defined as having any one of the following: del(13q) by cytogenetics or t(4;14), t(14;16), t(14;20), -17p ,+1q21 on FISH/cytogenetics. International Staging System (ISS) stage was based on beta2 microglobulin and albumin at diagnosis of symptomatic myeloma. These data were available for 18 patients (75%). The definitions of progression, stable disease and response were as per the International Myeloma Working Group criteria. Event time distributions for overall (OS) and progression-free survival (PFS) were estimated with the method of Kaplan and Meier, and compared using the log-rank statistic, or the Cox proportional hazards regression model. Factors associated with BiRd response were selected based on cross tabulations and logistic regression modeling. Results 24 patients with MM who had disease progression on Rd had clarithromycin added to their regimen at the time of progression on Rd. Median age was 61 years (range: 41-80 years), 10 (41.6%) female, 11 (45.8%) had high risk features on cytogenetics or FISH, 6 (25%) had a prior stem cell transplant. All patients had shown evidence of disease progression on Rd prior to addition of clarithromycin. Median duration on Rd immediately prior to addition of clarithromycin was 5.2 months (range: 1.6-37.8 months). The regimen was well tolerated and only 2 patients needed a clarithromycin dose reduction. One patient developed dyspepsia, metallic taste, nausea and diarrhea. A second patient experienced grade 3 transaminitis. 10 patients, 41.6% (95% CI: 22.1, 63.4), achieved ≥PR. The clinical benefit rate (CR+VGPR+PR+MR) was 45.8% (95% CI: 25.6, 67.2). The median time to response was 4.4 months (range: 1-13.6 months) and the median duration of response was 17.3 months (range: 7.4-130.5 months). Median overall survival was 25 months with a median follow-up of 27.5 months. The median progression free survival (PFS) was 4 months. Age and prior therapy were significant risk factors for PFS. Patients over the age of 60 had a higher hazard of progression or death than patients under the age of 60 (HR 3.48 95% CI 1.09-11.09, p=0.04). The hazard of progression or death was increased by a factor of 1.59 for each additional prior therapy HR= 1.59 (95% CI: 1.19, 2.11), p=0.002. Patients initially responding to Rd (n=10) were more likely to respond to BiRd (n=6), 60% (95% CI: 26.2, 87.8) compared to patients that did not have an initial response to Rd (n=14) in whom the response to BiRD (n=4) was 28.6% (95% CI: 8.4, 58.1), OR=3.75, p=0.13. High risk genetics, prior stem cell transplant, and prior response to Rd did not correlate with PFS or response to BiRd, although the numbers are small. Conclusion Addition of clarithromycin to lenalidomide and dexamethasone (BiRd) can overcome resistance to lenalidomide and dexamethasone in a subset of patients and lead to clinical durable responses. This retrospective data may serve the basis for prospective evaluation of this effect. Disclosures: Off Label Use: Addition of clarithromycin to overcome resistance to lenalidomide and dexamethasone.

Abstract Background: Therapeutic options for patients with Multiple myeloma (MM) whose disease has relapsed after a prior autologous stem cell transplant (SCT) include an expanding armamentarium of novel agents, often combined with traditional chemotherapy, or a second SCT, with no clear standard of care. Upfront tandem transplantation has been shown to improve both progression free survival and overall survival. But currently, there is little data regarding the application of tandem SCT in relapsed multiple myeloma patients. Methods: We retrospectively analyzed the outcomes of patients who underwent salvage melphalan-based tandem SCT for relapsed MM at University of Iowa Hospitals and clinics. Progression free survival (PFS) was defined as the time from date of the first salvage SCT to disease progression or death, whereas overall survival (OS) was defined from the date of the first salvage SCT to the date of death from any cause. Results: Between 2012 and 2015, 12 patients with MM received tandem autograft (total 24 transplants) for relapsed disease at our center. Conditioning was with VDT-melphalan 200mg/m2 (21/24), VDT-MEL 140mg/m2 (2/24) and Velcade, gemcitabine, BCNU, melphalan and dexamethasone (1/24). The median age at the salvage SCT was 48 years (range 37-58); 7 patients were female. 17% had high risk cytogenetics (including t(4;14), +1q, p53 loss) at the time of salvage SCT. Median time between previous transplant and progression of disease was 34 months (range 8-108). Of the 7 patients, who received re-induction therapy, 71% had chemotherapy refractory disease prior to salvage SCT. Response was assessed at 2-3 months post-SCT. Overall response rate was 92%. 7/12 (58%) patients achieved stringent complete remission, one patient achieved CR, one patient achieved near CR, 2/12 patients achieved VGPR and 1/12 had stable disease (SD). Following salvage tandem SCT, all patients received consolidation therapy with three drug combination, intended to be given for two years. Three patients have shown progressive disease at the time of analysis. The median PFS was 390 days (range 265- 1085) (Table-1); the median OS was 517 days (range 338-1085) (Table-2). Rate of progression free survival in the 10 evaluable patients at one year was 80%. There was no transplant related mortality. One patient died of progressive disease. Conclusions: Salvage tandem SCT is an effective strategy for relapsed MM and is especially effective in patients who had received less intensive therapy initially (single transplant and no maintenance therapy). Incorporation of novel agents (monoclonal antibodies and high doses of carfilzomib) into maintenance strategies may further improve outcomes. Figure 1.

We aimed to evaluate the efficacy and toxicity of paclitaxel combined with pazopanib in advanced angiosarcoma (AS). The primary end point was progression-free survival (PFS) rate at six months (PFSR6). Planned accrual was 44 patients in order to detect a PFSR6 of >55%, with an interim futility analysis of the first 14 patients. The study did not meet its predetermined interim target of 6/14 patients progression-free at 6 months. At the time of this finding, 26 patients had been enrolled between July 2014 and April 2016, resulting in an overrunning of 12 patients. After a median follow-up of 9.5 (IQR 7.7–15.4) months, PFSR6 amounted to 46%. Two patients had a complete and seven patients a partial response. Patients with superficial AS had a significantly higher PFSR6 (61% vs. 13%, p = 0.0247) and PFS (11.3 vs. 2.7 months, p < 0.0001) compared to patients with visceral AS. The median overall survival in the entire cohort was 21.6 months. A total of 10 drug-related serious adverse effects were reported in 5 patients, including a fatal hepatic failure. Although our study did not meet its primary endpoint, the median PFS of 11.6 months in patients with superficial AS appears to be promising. Taking recent reports into consideration, future studies should evaluate the safety and efficacy of VEGFR and immune checkpoint inhibitors with or without paclitaxel in a randomized, multiarm setting.

We evaluated outcomes of treatment with 5-fluorouracil (5-FU), doxorubicin, and streptozocin (FAS) in well-differentiated pancreatic neuroendocrine tumors (PanNETs) and its impact on subsequent therapy (everolimus or temozolomide). Advanced PanNET patients treated at our center from 1992 to 2013 were retrospectively reviewed. Patients received bolus 5-FU (400 mg/m2), streptozocin (400 mg/m2) (both IV, days 1-5) and doxorubicin (40 mg/m2 IV, day 1) every 28 days. Overall response rate (ORR) was assessed using RECIST version 1.1. Of 243 eligible patients, 220 were evaluable for ORR, progression-free survival (PFS), and toxicity. Most (90%) had metastatic, nonfunctional PanNETs; 14% had prior therapy. ORR to FAS was 41% (95% confidence interval [CI]: 36-48%). Median follow-up was 61 months. Median PFS was 20 (95% CI: 15-23) months; median overall survival (OS) was 63 (95% CI: 60-71) months. Cox regression analyses suggested improvement with first-line vs subsequent lines of FAS therapy. Main adverse events ≥ grade 3 were neutropenia (10%) and nausea/vomiting (5.5%). Dose reductions were required in 32% of patients. Post-FAS everolimus (n=108; 68% second line) had a median PFS of 10 (95% CI: 8-14) months. Post-FAS temozolomide (n=60; 53% > fourth line) had an ORR of 13% and median PFS of 5.2 (95% CI: 4-12) months. In this largest reported cohort of PanNETs treated with chemotherapy, FAS demonstrated activity without significant safety concerns. FAS did not appear to affect subsequent PFS with everolimus; this sequence is being evaluated prospectively. Responses were noted with subsequent temozolomide-based regimens although PFS was possibly limited by line of therapy.

Abstract BackgroundSoft tissue sarcoma（STS） is a malignant tumor of highly heterogeneous mesenchymal origin. STS has a biologic pattern and clinical transformation with localized invasive growth and susceptibility to hematogenous metastasis. Metastatic and recurrent soft tissue sarcoma may be treated by local therapeutic options, including surgery and radiation therapy. This study evaluated the safety and efficacy of SBRT for metastatic and recurrent soft tissue sarcoma.MethodsWe performed a retrospective analysis of 37 STS patients with 58 lesions treated with SBRT from 2009-2019 at our institution. We analyze the local control (LC), overall survival (OS), progression free survival (PFS) and toxicity rates of the patients.ResultThe median follow-up was 20 months（range 2 to 120 months）. One and two year LC rates were 75.3% and 55.2% [95% confidence interval (CI) 20–25 months]. Median OS was 24 months and the survival rates were 66.6%, 45% and 26.6% at 1, 2 and 3-year after SBRT. Median PFS were 11months (95% CI 8–18 months). No acute or chronic grade ≥ 3 toxicity was observed.ConclusionsIn patients with metastatic and recurrent STS, LC, OS and PFS were higher than expected. SBRT should be a proper treatment option for STS.

Abstract Introduction Ixazomib is an orally available proteasome inhibitor, shown to be safe and efficacious in combination with lenalidomide and dexamethasone (IRd regimen) in patients with relapsed and refractory multiple myeloma (RRMM) with 1-3 prior lines, demonstrating a progression free survival (PFS) benefit which was similar across cytogenetic risk groups (Tourmaline-MM1 phase 3 trial). A European real world data analysis of an IRd named patient program (NPP) outcomes in Greece (n=35), UK (n=46) and Check republic (n=57) showed similar favorable outcomes (Terpos et al, Blood 2017 130:3087). We aimed to analyze outcomes of ixazomib combinations among a multi-site cohort in the Israeli Myeloma registry. Overall response rate (ORR) was classified according to IMWG criteria. Primary endpoint was PFS, secondary endpoints included ORR, overall survival (OS), safety and tolerability. Patients A total of 78 patients across 7 sites, who received at least one cycle of ixazomib combination between June 2013 and June 2018 for treatment of RRMM were retrospectively included. Median age was 68 (range: 38-90). Male/Female ratio was 42/36. ISS (rISS) I/II/II was 30%/42%/27% (25%/54%/15%). Patient received between 1 and 7 prior lines of therapy, 66% received ixazomib in 2nd line, 18% in 3rd line. Overall, 89% of patients had been exposed to PIs (bortezomib 86%) prior to IRd, 41% to IMiDs (thalidomide 28% lenalidomide 22% and pomalidomide 6%), and 35% had undergone autologous transplantation (ASCT). Induction treatment was mostly bortezomib based (85%), most frequently VCD (62%). FISH cytogenetics were available for 60 patients, 29 (48%) had high or intermediate risk aberrations (t(4:14) 12 pts, amp 1q21 12 pts, del17p 9 pts). Disease aggressiveness was classified by treating physician as indolent (rapid control to protect from target organ damage not required) vs aggressive (imminent target organ damage) in 63% vs 27%, respectively. 60 (77%) of the 78 patients received ixazomib via a named patient program, the rest via national or private healthcare provider. Results Median time of follow up from first ixazomib dose was 22 months (range: 1-39 months), and 54 months from diagnosis of myeloma. Treatment is ongoing in 44 (56%) patients with a median duration of 19 months (range: 1-29). Among patients who discontinued treatment, the median duration was 9 months (1-31). Ixazomib was combined with lenalidomide, pomalidomide, and daratumumab in 69%, 9% and 4%, respectively. Overall response rate was 88% - CR 10%, VGPR 36%, PR 42%. Progression free survival was 78% and 54% at 12 and 24 months, respectively (fig1a). A worse PFS was found with physician assessment of aggressive vs indolent disease (14.5 vs 25.9 months, p=0.001), and with post induction progression free period (PFS1) ≤ 24 months vs. >24 months (23.9 vs 31.5 months, p=0.038) (fig 1b); age >=65 trended towards a worse PFS (p=0.058). Poor cytogenetic risk, prior exposure to bortezomib, prior auto transplant, and number of prior lines of therapy did not affect PFS or ORR. OS from first ixazomib administration was 90% and 81% at 12 and 24 months, respectively; median OS was not reached (fig1a). Any (grade 3-4) toxicity considered by investigator as related to ixazomib was reported in 70% (18% grade 3-4), including neutropenia 14% (6%), anemia 19% (6%), thrombocytopenia 17% (5%), nausea and vomiting 17% (1%), DVT/PE 4% (1%), neutropenic infection 0 (4%), peripheral neuropathy 14% (3%), diarrhea 14% (3%), rash 10% (4%), pneumonia 5% (3%). There were no ixazomib related deaths. Dose reduction or discontinuation due to toxicity occurred in 28% and 12%, respectively. Conclusion Our data shows ixazomib-based combinations are efficacious and safe regimens for patients with RRMM, achieving ORR of 88%, at 2nd as well as later lines of therapy, regardless to cytogenetic risk. Over a median follow up of almost 2-years, 54% remained progression free at 24 months. An ixazomib based regimen may be particularly attractive for patients who remain progression free for more than 24 months after a bortezomib induction and for patients with a more indolent disease phenotype.

PURPOSE Nivolumab + ipilimumab (nivo + ipi) is highly efficacious but has high toxicity. Standard treatment in advanced melanoma is four doses of nivo + ipi followed by nivo alone. Whether four doses of nivo + ipi are needed is unclear. METHODS The Adaptively Dosed ImmunoTherapy Trial (ADAPT-IT) study ( NCT03122522 ) is a multicenter, single-arm phase II clinical trial. Patients received two doses of nivo (1 mg/kg) + ipi (3 mg/kg) followed by a computed tomography scan at week 6. Patients without new lesions or index lesion tumor growth of > 4% had protocol-defined early favorable antitumor effect (FATE) and ceased nivo + ipi, transitioning to nivo monotherapy. Patients without FATE at week 6 received the standard third and fourth doses of nivo + ipi followed by nivo monotherapy. The primary end point was response rate by RECIST 1.1 at week 12. Secondary end points included additional efficacy assessments and safety. RESULTS Sixty patients were enrolled; 41 patients (68%) had FATE at week 6 and met criteria for stopping nivo + ipi. Best overall response rates by RECIST at week 12 or any time afterward were 48% (95% CI, 35 to 62) and 58% (95% CI, 45 to 71), respectively. With a median follow-up of 25 months, the estimated 18-month progression-free survival and overall survival are 52% and 80%, respectively. Fifty seven percent of patients had grade 3-5 treatment-related toxicity. CONCLUSION The efficacy and toxicity of standard four dose nivo + ipi induction therapy in melanoma is likely driven by the first two doses. An interim computed tomography scan after two doses guided cessation of combination dosing and identified almost all responders. Longer follow-up and further study are needed to fully understand the implications of a shortened induction course of nivo + ipi.
