Abstract Background The combination of PD-1/PD-L1 inhibitor and chemotherapy has been clinically confirmed to be beneficial as the first-line treatment of patients with advanced NSCLC. This study aimed to assess the effect of nivolumab + docetaxel versus nivolumab monotherapy in patients with NSCLC after the failure of platinum doublet chemotherapy. Materials and methods The efficacy and toxicity of nivolumab + docetaxel combination therapy versus nivolumab monotherapy were compared in this retrospective study. Primary endpoint of the study was progression-free survival (PFS), and the secondary endpoints were objective response rate (ORR), overall survival (OS), and toxicity. Results Between November 2017 and December 2019, 77 patients were included in this study, with 58 patients in the nivolumab group and 19 in the nivolumab + docetaxel group. The median follow-up was 18 months, and the PFS was 8 months for patients receiving nivolumab + docetaxel and 2 months for those receiving nivolumab alone (p = 0.001), respectively. Nivolumab + docetaxel showed superior OS compared with nivolumab, with the median OS unreached versus 7 months (p = 0.011). Among patients without EGFR/ALK variation, compared to nivolumab monotherapy, nivolumab + docetaxel showed better PFS (p = 0.04) and OS (p  = 0.05). There was no significant difference in grade 3–4 adverse events (AEs) between the two groups (p = 0.253). Conclusions The combination of nivolumab and docetaxel demonstrated a meaningful improvement in progression-free survival and overall survival compared to nivolumab monotherapy, in patients with NSCLC after the failure of platinum doublet chemotherapy, irrespective of EGFR/ALK variation status.

Introduction Almost half of patients with non-small-cell lung cancer (NSCLC) are diagnosed at an advanced stage. Our aim was to assess the effects of adding necitumumab to chemotherapy in patients with stage IV NSCLC. Material and methods A comprehensive literature search was performed according to pre-specified inclusion and exclusion criteria. Data on overall survival, progression-free survival, objective response rate and adverse events were extracted. A meta-analysis was performed to obtain pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) for time-to-event data and pooled odds ratio (OR) with 95% CI for dichotomous outcomes. Results The meta-analysis included four randomized clinical trials with 2074 patients. The pooled results showed significant improvement for overall survival (HR = 0.87 (95% CI 0.79–0.95), p = 0.004) when necitumumab was added to chemotherapy in patients with advanced NSCLC. No statistically significant improvement was noted for progression-free survival and objective response rate (HR = 0.83 (95% CI 0.69–1.01), p = 0.06 and OR = 1.46 (95% CI 0.90–2.38), p = 0.13, respectively). Subgroup analysis showed that in patients with non-squamous NSCLC, there was no benefit in overall survival and objective response rate. Patients with advanced NSCLC who received necitumumab were at the highest odds of developing a skin rash (OR = 14.50 (95% CI 3.16–66.43), p = 0.0006) and hypomagnesaemia (OR = 2.77 (95% CI 2.23–3.45), p < 0.00001), while the OR for any grade ≥3 adverse event was 1.55 (95% CI 1.28–1.87, p < 0.00001). Conclusions The addition of necitumumab to standard chemotherapy in a first-line setting in patients with stage IV NSCLC results in a statistically significant improvement in overall survival, while the results were not significant for progression-free survival and objective response rate.

Abstract BACKGROUND Temozolomide (TMZ) is the cornerstone for glioblastoma (GBM) treatment. A significant proportion of patients develops hematologic toxicities with limited investigations on outcomes and risk factors for their development. METHODS Our study combines data from the two largest group trials, RTOG 0525 and RTOG 0825, to analyze serious hematologic adverse events (HAE) associated with TMZ therapy for GBM. We analyzed frequency and outcomes of HAE during chemoradiation. RESULTS 1154 patients were evaluated with a median age of 57 years. Over 79% of patients developed HAE during the entire course of GBM treatment. During chemoradiation the most common HAE during chemoradiation was lymphopenia (41.5%), followed by thrombocytopenia (39.0%), and anemia (35.3%). Of these, 34.1% were severe (Grade 3 or 4) and 65.9% were mild (grade 1 or 2). During maintenance the most common HAE was leukopenia (50.7%), followed by neutropenia (50.4%), and lymphopenia (45.3%). MGMT methylation was not associated with HAEs. A history of HAEs during chemoradiation was a protective factor for developing HAEs during maintenance. MGMT methylated and age younger than 50 were protective factors for mortality. Patients that presented HAEs anytime during treatment had a longer overall survival and progression free survival. There was no significant difference in survival between mild or severe HAEs. CONCLUSION HAE are common during chemoradiation with TMZ for GBM, but are more commonly grade 1 or 2 per CTCAE. HAE during GBM treatment is associated with decreased progression free survival and overall survival.

PURPOSE Nivolumab 1 mg/kg plus ipilimumab 3 mg/kg (NIVO1+IPI3) is approved for first-line treatment of patients with advanced melanoma in several countries. We conducted a phase IIIb/IV study (CheckMate 511) to determine if nivolumab 3 mg/kg plus ipilimumab 1 mg/kg (NIVO3+IPI1) improves the safety profile of the combination. PATIENTS AND METHODS Patients (N = 360) age 18 years or older with previously untreated, unresectable stage III or IV melanoma were randomly assigned 1:1 to NIVO3+IPI1 or NIVO1+IPI3 once every 3 weeks for four doses. After 6 weeks, all patients received NIVO 480 mg once every 4 weeks until disease progression or unacceptable toxicity. The primary end point was a comparison of the incidence of treatment-related grade 3 to 5 adverse events (AEs) between groups. Secondary end points included descriptive analyses of objective response rate, progression-free survival, and overall survival. The study was not designed to formally demonstrate noninferiority of NIVO3+IPI1 to NIVO1+IPI3 for efficacy end points. RESULTS At a minimum follow-up of 12 months, incidence of treatment-related grade 3 to 5 AEs was 34% with NIVO3+IPI1 versus 48% with NIVO1+IPI3 ( P = .006). In descriptive analyses, objective response rate was 45.6% in the NIVO3+IPI1 group and 50.6% in the NIVO1+IPI3 group, with complete responses in 15.0% and 13.5% of patients, respectively. Median progression-free survival was 9.9 months in the NIVO3+IPI1 group and 8.9 months in the NIVO1+IPI3 group. Median overall survival was not reached in either group. CONCLUSION The CheckMate 511 study met its primary end point, demonstrating a significantly lower incidence of treatment-related grade 3-5 AEs with NIVO3+IPI1 versus NIVO1+IPI3. Descriptive analyses showed that there were no meaningful differences between the groups for any efficacy end point, although longer follow up may help to better characterize efficacy outcomes.

Background: Anlotinib is a multi-target anti-angiogenic agent. This retrospective study aimed to evaluate the efficacy and safety of anlotinib alone or in combination with temozolomide for the treatment of recurrent high-grade glioma.Materials and Methods: The clinical data of patients with recurrent high-grade glioma treated with anlotinib alone or in combination with temozolomide in our cancer center were collected and analyzed. Treatment response was evaluated according to the response assessment for neuro-oncology criteria. Progression-free survival, progression-free survival at 6 months, overall survival, and overall survival at 12 months were evaluated by Kaplan–Meier method and compared by log-rank test.Results: Between August 2019 and December 2020, 31 patients with recurrent high-grade glioma (21 of grade 4 and 10 of grade 3) were enrolled in this study. Seventeen patients received anlotinib alone and 14 received anlotinib plus temozolomide. All patients were heavily treated, the median lines of previous treatments were 2, and the median Karnofsky score was 60. At the data cutoff date, the median progression-free survival was 4.5 months and the progression-free survival at 6 months was 43.5%. The median overall survival was 7.7 months, and the overall survival at 12 months was 26.7%. The progression-free survival at 6 months and the overall survival at 12 months for 21 patients with grade 4 glioma was 40.2 and 27.9%, respectively. The tumor objective response rate was 41.9% in all patients and 33.3% in patients with grade 4 glioma. No grade 3 or worse treatment-related adverse events were recorded during the treatment.Conclusion: Anlotinib alone or in combination with temozolomide showed encouraging efficacy and favorable tolerability in patients with recurrent high-grade glioma who had been heavily treated.

Purpose Gefitinib is a small molecule inhibitor of the epidermal growth factor receptor tyrosine kinase. We conducted a phase III trial to evaluate whether gefitinib improves survival as sequential therapy after platinum-doublet chemotherapy in patients with advanced non–small-cell lung cancer (NSCLC). Patients and Methods Chemotherapy-naïve patients with advanced stage (IIIB/IV) NSCLC, Eastern Cooperative Oncology Group performance status of 0 to 1, and adequate organ function were randomly assigned to either platinum-doublet chemotherapy up to six cycles (arm A) or platinum-doublet chemotherapy for three cycles followed by gefitinib 250 mg orally once daily, until disease progression (arm B). Patients were stratified by disease stage, sex, histology, and chemotherapy regimens. The primary end point was overall survival; secondary end points included progression-free survival, tumor response, safety, and quality of life. Results Between March 2003 and May 2005, 604 patients were randomly assigned. There was a statistically significant improvement in progression-free survival in arm B (hazard ratio [HR], 0.68; 95% CI, 0.57 to 0.80; P < .001); however, overall survival results did not reach statistical significance (HR, 0.86; 95% CI, 0.72 to 1.03; P = .11). In an exploratory subset analysis of overall survival by histologic group, patients in arm B with adenocarcinoma did significantly better than patients in arm A with adenocarcinoma (n = 467; HR, 0.79; 95% CI, 0.65 to 0.98; P = .03). Conclusion This trial failed to meet the primary end point of OS in patients with NSCLC. The exploratory subset analyses demonstrate a possible survival prolongation for sequential therapy of gefitinib, especially for patients with adenocarcinoma.

e20524 Background: Immunotherapy targeting the PD1/PDL1 checkpoint pathway represents an important innovation in lung cancer treatment. In our research, we evaluate the correlation of PD-L1 expression with clinical outcomes (progression free survival, overall survival, objective response rate) in lung cancer patients in 4 centers in Lebanon. Methods: The 57 patients enrolled in this observational study were stage IIIB/IV NSCLC and SCLC who received immunotherapy with nivolumab, pembrolizumab or atezolizumab at any line of treatment, and were recruited between February 2012 and august 2018. Immunotherapy was continued until progression, death or unacceptable toxicity. PD-L1 expression was assessed on tumor samples either on diagnosis or at progression. Patients were divided into 3 categories according to PD-L1 level (< 1, 1-49, > 50%). Progression free survival defines the time from randomization to disease progression after each line of therapy. Overall survival defines time from randomization to death from any cause. Results: 70.18% had adenocarcinoma, 26.32% had squamous cell carcinoma, 1.75% had small cell lung cancer and one pathology was missing from the file. 66.66% were stage IV at diagnosis, 26.31% were stage 3. PD-L1 expression was > 50% in 40.35% of patients, 24.56% had a level between 1 and 50% and the remaining had a value of less than 1%. PD-L1 was missing or not done in 15.79%. Median PFS was 13.9 months. Median OS was 14.2 months. 22.81% received immunotherapy as first line and 75% of the remaining patients upon first progression. PFS1 was 4.2 months. Mean time to first progression on immunotherapy was 3.6 months in patients with PD-L1 > 50%, 10.5 months in PD-L1 between 1 and 50% and 14.3 months in those who had PD-L1 < 1%. At the date of data cutoff, 49.12 % of patients were still receiving immunotherapy. No grade 3 or 4 immune related adverse events were seen during follow-up. Conclusions: The efficacy and safety of anti-PD-1 medications for advanced NSCLC were comparable in real-world and clinical settings. Prediction of treatment response from tumor PD-L1 expression seemed less practical than that was expected

Doublet Chemotherapy

Purpose Doublet chemotherapy is more effective than single-agent as first-line treatment of advanced non–small-cell lung cancer (NSCLC). As second-line treatment, several randomized trials have been performed comparing single-agent with doublet chemotherapy, but each trial had an insufficient power to detect potentially relevant differences in survival. Methods We performed meta-analysis of individual patient data from randomized trials, both published and unpublished, comparing single-agent with doublet chemotherapy as second-line treatment of advanced NSCLC. Primary end point was overall survival (OS). All statistical analyses were stratified by trial. Results Eight eligible trials were identified. Data of two trials were not available, and data of six trials (847 patients) were collected. Median age was 61 years. Performance status was 0 or 1 in 90%; 80% of patients had received previous platin-based chemotherapy. OS was not significantly different between arms (P = .32). Median OS was 37.3 and 34.7 weeks in the doublet and single-agent arms, respectively. Hazard ratio (HR) was 0.92 (95% CI, 0.79 to 1.08). Response rate was 15.1% with doublet and 7.3% with single-agent (P = .0004). Median progression-free survival was 14 weeks for doublet and 11.7 weeks for single agent (P = .0009; HR, 0.79; 95% CI, 0.68 to 0.91). There was no significant heterogeneity among trials for the three efficacy outcomes. Patients treated with doublet chemotherapy had significantly more grade 3 to 4 hematologic (41% v 25%; P < .0001) and grade 3 to 4 nonhematologic toxicity (28% v 22%; P = .034). Conclusion Doublet chemotherapy as second-line treatment of advanced NSCLC significantly increases response rate and progression-free survival, but is more toxic and does not improve overall survival compared to single-agent.

e16198 Background: There is relatively limited data guiding optimal treatment algorithms for inoperable or metastatic neuroendocrine tumours (NETs). The randomised NETTER 1 study established PRRT as a standard of care in midgut NET. The aim of this study was to retrospectively review the efficacy and safety of patients treated with 177Lu-DOTATATE at Royal Brisbane and Women’s Hospital. Methods: Consecutive patients with unresectable or metastatic NET who received their first 177Lu-DOTATATE therapy between 2010 and 2017 were identified. Paragangliomas were excluded. Response rates, progression free survival (PFS) and overall survival (OS) were assessed via a combination of chart review, post-therapeutic 68Ga DOTATATE PET/CT and multi-disciplinary meeting decisions. Gr3/4 haematological and renal safety data was analysed via chart review. Progression free survival (PFS) and overall survival (OS) were assessed via the Kaplan-Meier method. Results: 123 consecutive patients were included in the analysis (57% male, median age 61). Primary site: 41% gastroenteric, 34% pancreatic, 10% lung, 6% colon/rectum, 9% other. Grade 1 (42%), Grade 2 (31%) Grade 3 (6%), unknown (21%). 76% of patients had previously received somatostatin analogues. 80% received four cycles (with persistent myelosuppression the most common cause of ceasing therapy early). 20% of patients received concurrent chemotherapy (10% capecitabine, 10% capecitabine and temozolomide). For the entire cohort, median follow up was 51 months. Median PFS, 34.2 months (95% CI, 30.3 – 38.17) and median OS, 61 months (95% CI, 54.2– 67.8). There was no significant difference in PFS or OS between small bowel and pancreatic patients. Response rates to PRRT included complete response (n = 4, 3%), stable or responding disease (n = 96, 78%), progressive disease (n = 22, 18%), not assessable (1, 1%). Grade 3 or 4 thrombocytopenia, neutropenia or anaemia occurred in less than 1% of patients. Confirmed acute leukaemia occurred in three patients. One patient had grade 3 renal toxicity secondary to treatment. 26 patients received retreatment with 177Lu-DOTATATE at progression with median time to re-treatment of 35 months. Conclusions: This single centre, retrospective audit confirms the efficacy of 177Lu-DOTATATE in the treatment of unresectable and metastatic NETs. Treatment was associated with low rates of severe haematological or renal adverse events. Our results are comparable to similar published reviews.

Purpose Phosphatidylinositol 3-kinase (PI3K) signaling is critical for the proliferation and survival of malignant B cells. Copanlisib, a pan-class I PI3K inhibitor with predominant activity against PI3K-α and -δ isoforms, has demonstrated efficacy and a manageable safety profile in patients with indolent lymphoma. Patients and Methods In this phase II study, 142 patients with relapsed or refractory indolent lymphoma after two or more lines of therapy were enrolled to receive copanlisib 60 mg intravenously on days 1, 8, and 15 of a 28-day cycle. The primary end point was objective response rate; secondary end points included duration of response, progression-free survival, and overall survival. In addition, safety and gene expression were evaluated. Results Median age was 63 years (range, 25 to 82 years), and patients had received a median of three (range, two to nine) prior regimens. The objective response rate was 59% (84 of 142 patients); 12% of patients achieved a complete response. Median time to response was 53 days. Median duration of response was 22.6 months, median progression-free survival was 11.2 months, and median overall survival had not yet been reached. The most frequent treatment-emergent adverse events were transient hyperglycemia (all grades, 50%; grade 3 or 4, 41%) and transient hypertension (all grades, 30%; grade 3, 24%). Other grade ≥3 events included decreased neutrophil count (24%) and lung infection (15%). High response rates to copanlisib were associated with high expression of PI3K/B-cell receptor signaling pathway genes. Conclusion PI3K-α and -δ inhibition by copanlisib demonstrated significant efficacy and a manageable safety profile in heavily pretreated patients with relapsed or refractory indolent lymphoma.

e16567 Background: ICI/TKI combinations are a new standard of care for the initial treatment (tx) of mRCC. Efficacy and toxicity of such combination regimens beyond the first-line (1L) setting remain unknown. Methods: We retrospectively reviewed charts for adult patients (pts) receiving an ICI/TKI combination in any line of tx for mRCC of any histology at one of two academic centers as of May 1, 2020. ICIs included pembrolizumab (Pm), nivolumab (Ni), ipilimumab (Ip), or avelumab (Av); TKIs included sunitinib (Su), axitinib (Ax), pazopanib (Pz), lenvatinib (Ln), or cabozantinib (Ca). Clinical data including pt demographics, histology, International mRCC Database Consortium (IMDC) risk group, tx history, and ICI/TKI tx and toxicity details were recorded. Outcomes included objective response rate (ORR), median progression-free survival (mPFS), and safety, analyzed via descriptive statistics and the Kaplan-Meier method. Results: Of 85 pts, 69 (81%) were male and 67 (79%) had clear cell histology. IMDC risk was favorable (24%), intermediate (54%), poor (20%), and unknown (2%). 39% had ICI/TKI tx in the 1L setting. ICI/TKI regimens included Pm/Ax (33%), Ni/Ca (25%), Ni/Ax (20%), Av/Ax (11%), Ni/Ip/Ca (8%), Ni/Su (2%), and Ni/Ln (1%). ORR and mPFS stratified by line of tx and prior tx are shown in the table. Of 52 pts who received ICI/TKI tx as salvage (after 1L), 52% had a grade 3 or higher (≥G3) adverse event (AE), of which the most common were anorexia (13.5%), diarrhea and hypertension (11.5% each), and fatigue (9.6%). 65% of pts on salvage ICI/TKI tx stopped tx for progression/death, while 16% stopped tx for ≥G3 AE. ≥G3 AE rates by line of tx were 62.5% (2L), 50% (3L), and 45% (≥4L). Conclusions: ICI/TKI combination therapy is effective and safe beyond the 1L setting. Prior tx history appears to impact efficacy but has less of an effect on safety/tolerability. These observations will need to be confirmed in prospective studies.[Table: see text]
