e19075 Background: Chidamide (CS055) is a new benzamide type of histone deacetylase (HDAC) inhibitor with subtype selective activity against HDAC1, 2, 3 and 10. Synergistic effect of chidamide combined with paclitaxel and carboplatin (PC) have been demonstrated in various in vitro studies. Chidamide has shown well-tolerated and favorable PK profiles in patients (pts) with advanced solid tumors and lymphomas.This phase Ib study was designed to assess the safety and pharmacokinetics of chidamide plus PC in pts with advanced non-small cell lung cancer (NSCLC). Methods: Chemonaive pts with stage IIIb or IV NSCLC were treated with the escalating doses of chidamide (20, 25, and 30mg) plus PC. Chidamide was oral administered twice per week. Paclitaxel (175 mg/m2) and carboplatin (AUC 5 mg·min/mL) were given both on day 1 every 3 weeks. Pts with response or stable disease after four cycles maintained single chidamide therapy until disease progression or unacceptable toxicity. Results: No DLT was observed in the 20 mg (n=3) and 25 mg (n=3) cohorts. 2 DLTs occurred in the 30 mg cohort (n=4), where 1 pt experienced grade 4 thrombocytopenia at the end of the first cycle, and the other developed grade 3 neutropenia and grade 2 thrombocytopenia resulting in the delay of the 2nd treatment cycle for > 14 days. Therefore, chidamide in 25 mg was determined to be the MTD with this combination regimen. ≥ Grade 3 toxicities were thrombocytopenia (n=3) and neutropenia (n=1). 1 pt experienced grade 1 prolonged QTc. Co-administration had no significant effect on clearance of either chidamide or paclitaxel. 1 pt in the 20 mg cohort had confirmed partial response. Of 5 pts with brain metastases, 2 of them had complete disappearance of brain tumors after 4-cycle treatment. Conclusions: Chidamide plus PC was safe and well tolerated, with no apparent chidamide-paclitaxel pharmacokinetic interaction. Preliminary efficacy results suggest that chidamide combined with PC could provide benefit to NSCLC pts, with a potential interest of further observation of brain metastasis control in NSCLC with this regimen.

BackgroundHistone deacetylase (HDAC) overexpression has been documented in various cancers and may be associated with worse outcomes. Data from early-phase studies of advanced non-small cell lung cancer (NSCLC) suggest encouraging antitumor activity with the combination of an HDAC inhibitor and either platinum-based chemotherapy or an EGFR inhibitor; however, toxicity is a limiting factor in the use of pan-HDAC inhibitors. Selective inhibition of HDAC6 may represent a potential therapeutic target and preclinical studies revealed immunomodulatory effects with HDAC6 inhibition, suggesting the potential for combination with immune checkpoint inhibitors. This phase Ib, multicenter, single-arm, open-label, dose-escalation study investigated the HDAC6 inhibitor ACY-241 (citarinostat) plus nivolumab in patients with previously treated advanced NSCLC who had not received a prior HDAC or immune checkpoint inhibitor.MethodsThe orally administered ACY-241 dose was escalated (180, 360, or 480 mg once daily). Nivolumab was administered at 240 mg (day 15 of cycle 1, then every 2 weeks thereafter). The primary endpoint was to determine the maximum tolerated dose (MTD) of ACY-241 plus nivolumab. Secondary endpoints included safety, tolerability, and preliminary antitumor activity. Pharmacodynamics was an exploratory endpoint.ResultsA total of 18 patients were enrolled, with 17 patients treated. No dose-limiting toxicities (DLTs) occurred with ACY-241 at 180 or 360 mg; 2 DLTs occurred at 480 mg. The MTD of ACY-241 was 360 mg. The most common grade ≥ 3 treatment-emergent adverse events were dyspnea (n = 3; 18%) and pneumonia (n = 3; 18%). At the 180-mg dose, 1 complete response and 2 partial responses (PRs) were observed. At the 360-mg dose, 3 PRs were observed; 1 patient achieved stable disease (SD) and 1 experienced progressive disease (PD). At the 480-mg dose, no responses were observed; 1 patient achieved SD and 3 experienced PD. Acetylation analyses revealed transient increases in histone and tubulin acetylation levels following treatment. An increase in infiltrating total CD3+ T cells was observed following treatment.ConclusionsThe study identified an MTD for ACY-241 plus nivolumab and the data suggest that the combination may be feasible in patients with advanced NSCLC. Responses were observed in patients with advanced NSCLC. Clinical Trial Registrationhttps://clinicaltrials.gov/ct2/show/NCT02635061 (identifier, NCT02635061).

AbstractTreatment-related toxicity is an important component in non-small cell lung cancer (NSCLC) management decision-making. Our aim was to evaluate and compare the toxicity rates of curative and palliative radiotherapy with and without chemotherapy. This meta-analysis provides better quantitative estimates of the toxicities compared to individual trials. A systematic review of randomised trials with > 50 unresectable NSCLC patients, treated with curative or palliative conventional radiotherapy (RT) with or without chemotherapy. Data was extracted for oesophagitis, pneumonitis, cardiac events, pulmonary fibrosis, myelopathy and neutropenia by any grade, grade ≥ 3 and treatment-related deaths. Mantel–Haenszel fixed-effect method was used to obtain pooled risk ratio. Forty-nine trials with 8609 evaluable patients were included. There was significantly less grade ≥ 3 acute oesophagitis (6.4 vs 22.2%, p < 0.0001) and any grade oesophagitis (70.4 vs 79.0%, p = 0.04) for sequential CRT compared to concurrent CRT, with no difference in pneumonitis (grade ≥ 3 or any grade), neutropenia (grade ≥ 3), cardiac events (grade ≥ 3) or treatment-related deaths. Although the rate of toxicity increased with intensification of treatment with RT, the only significant difference between treatment regimens was the rate of oesophagitis between the use of concurrent and sequential CRT. This can aid clinicians in radiotherapy decision making for NSCLC.

3015 Background: Mirzotamab clezutoclax (ABBV-155) is a first-in-class antibody drug conjugate comprised of a BCL-XL (B-cell lymphoma - extra long) inhibitor, solubilizing linker, and a monoclonal anti-B7H3 antibody. Methods: Patients (pts) with relapsed and/or refractory (R/R) solid tumors were administered mirzotamab clezutoclax with or without paclitaxel. Dose escalation of mirzotamab clezutoclax was guided by Bayesian continual reassessment. Primary outcomes were to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D). Secondary outcomes: safety, pharmacokinetics, and overall response rate per RECIST v1.1. Results: As of November 6, 2020, 31 pts received mirzotamab clezutoclax monotherapy (monoTx) and 28 pts received combination therapy with paclitaxel (comboTx). Overall demographics: median age 62 years (range 25–79); 61% female; 86% white; 24% ECOG 0, 76% ECOG 1; 51% had > 3 prior systemic therapies. The median duration of mirzotamab clezutoclax exposure was 3 cycles (range 1–14) for monoTx and 5 cycles (range 1–14) for comboTx. There were no dose limiting toxicities (DLT) reported with monoTx. In comboTx, 2 pts experienced a DLT: Grade 4 neutrophil count decreased and Grade 3 lymphocyte count decreased considered related to paclitaxel. 97% of all pts had adverse events (AEs). The most common AEs (in ≥20% of pts) overall were fatigue (39%), nausea (25%), diarrhea and arthralgia (22% each), vomiting and hypokalemia (20% each). AEs in ≥5 pts related to mirzotamab cleuzutoclax were fatigue (27%), diarrhea (12%), and nausea (9%). Related Grade 3/4 AEs overall (in > 1 patient) included anemia, lymphocyte count decreased, fatigue, and diarrhea (3% each). One patient on monoTx experienced a fatal cardiac arrest. No fatal AEs occurred on comboTx. Responses were observed with comboTx as shown in the Table. Conclusions: Mirzotamab clezutoclax as monotherapy and with paclitaxel demonstrates a tolerable safety profile (MTD not reached) with anti-tumor activity in R/R solid tumors. Further investigation in prospectively-selected B7H3 positive tumors as monoTx in pts with R/R small cell lung cancer and with paclitaxel in pts with R/R breast cancer and docetaxel in pts with R/R non-small cell lung cancer in the dose expansion phase is ongoing.

PurposeThis study evaluated the efficacy and safety of pemetrexed, carboplatin, and bevacizumab followed by maintenance pemetrexed and bevacizumab in patients with chemotherapy-naive stage IIIB (effusion) or stage IV nonsquamous non–small-cell lung cancer (NSCLC).Patients and MethodsPatients received pemetrexed 500 mg/m2, carboplatin area under the concentration-time curve of 6, and bevacizumab 15 mg/kg every 3 weeks for six cycles. For patients with response or stable disease, pemetrexed and bevacizumab were continued until disease progression or unacceptable toxicity.ResultsFifty patients were enrolled and received treatment. The median follow-up was 13.0 months, and the median number of treatment cycles was seven (range, one to 51). Thirty patients (60%) completed ≥ six treatment cycles, and nine (18%) completed ≥ 18 treatment cycles. Among the 49 patients assessable for response, the objective response rate was 55% (95% CI, 41% to 69%). Median progression-free and overall survival rates were 7.8 months (95% CI, 5.2 to 11.5 months) and 14.1 months (95% CI, 10.8 to 19.6 months), respectively. Grade 3/4 hematologic toxicity was modest—anemia (6%; 0), neutropenia (4%; 0), and thrombocytopenia (0; 8%). Grade 3/4 nonhematologic toxicities were proteinuria (2%; 0), venous thrombosis (4%; 2%), arterial thrombosis (2%; 0), fatigue (8%; 0), infection (8%; 2%), nephrotoxicity (2%; 0), and diverticulitis (6%; 2%). There were no grade 3 or greater hemorrhagic events or hypertension cases.ConclusionThis regimen, involving a maintenance component, was associated with acceptable toxicity and relatively long survival in patients with advanced nonsquamous NSCLC. These results justify a phase III comparison against the standard-of-care in this patient population.

BackgroundImmune checkpoint inhibitors (ICI) are standard treatment for stage III/IV non-small cell lung cancer (NSCLC). ICIs may cause immune-related adverse events (irAEs) often requiring corticosteroids or other immunosuppressive therapy and are associated with increased risk of opportunistic infections.1 2 The burden of infectious complications in NSCLC patients (pts) treated with ICIs is poorly described.MethodsWe retrospectively reviewed NSCLC pts treated with ICIs between 2016–2020 at a large tertiary academic center. An infectious complication related to ICIs was defined as a pathogen-confirmed or clinically diagnosed infection requiring antimicrobials during or within 3 months of ICI discontinuation. High-grade infections were defined as those requiring IV antibiotics (grade 3), life-threatening or requiring ICU stay (grade 4), or resulting in death (grade 5). irAEs were defined by the treating provider and treated according to standard guidelines. Patient demographics, treatment data, cancer outcomes, infectious complications, and irAE details were annotated in an IRB-approved database. An AE treated as both an infection and/or irAE with antibiotics and immunosuppression was coded as a concomitant irAE/infection event. The association between patient features and infectious complications was examined using logistic regression. Treatment and disease characteristics for concomitant irAE with infection were also described.Results302 ICI-treated NSCLC pts were included. 211 pts received PD-1 monotherapy and 91 received PD-1 therapy with CTLA-4 therapy, chemotherapy, or other investigational therapy. The majority (175/302, 57.9%) had a documented infection (bacterial=138, viral=17, fungal=19, mycobacterial=1) during or within 3 months of ICI discontinuation. Grade ≥3 infections occurred in 33.4% of pts (101/302). Pulmonary infections were most common (35.4%), followed by gastrointestinal, urinary, and skin (<10%, each). A subset of pts were treated as having concomitant irAE/infection events (63/302, 20.9%). Among 63 pts who experienced irAEs, pneumonitis occurred most commonly (47/63, 74.6%) followed by colitis (7/63, 11.1%); other irAEs (hepatitis, myocarditis, thyroiditis) occurred in <3 patients each. A concomitant event was associated with a trend toward higher odds of hospitalization (OR 3.91, CI 0.5–30.76) when adjusted for grade ≥3 infection. Similarly, steroid use within one month prior to infection, was also associated with a trend toward higher odds of hospitalization (OR 8.88, CI 0.81–97.15), adjusted for grade ≥3 infection.ConclusionsIn this retrospective study of NSCLC pts treated with ICIs, the majority experienced infections during or within 3 months of ICI discontinuation. The most common infections were bacterial pulmonary in origin. Concomitant irAE/infection was associated with trend toward higher odds of hospitalization.ReferencesHamashima R, Uchino J, Morimoto Y, et al.

Abstract Background Whereas there are many pharmacological interventions prescribed for patients with advanced anaplastic lymphoma kinase (ALK)- rearranged non-small cell lung cancer (NSCLC), comparative data between novel generation ALK-tyrosine kinase inhibitors (TKIs) remain scant. Here, we indirectly compared the efficacy and safety of first-line systemic therapeutic options used for the treatment of ALK-rearranged NSCLC. Methods We included all phase 2 and 3 randomised controlled trials (RCTs) comparing any two or three treatment options. Eligible studies reported at least one of the following outcomes: progression free survival (PFS), overall survival (OS), objective response rate (ORR), or adverse events of grade 3 or higher (Grade ≥ 3 AEs). Subgroup analysis was conducted according to central nervous system (CNS) metastases. Results A total of 9 RCTs consisting of 2484 patients with 8 treatment options were included in the systematic review. Our analysis showed that alectinib (300 mg and 600 mg), brigatinib, lorlatinib and ensartinib yielded the most favorable PFS. Whereas there was no significant OS or ORR difference among the ALK-TKIs. According to Bayesian ranking profiles, lorlatinib, alectinib 600 mg and alectinib 300 mg had the best PFS (63.7%), OS (35.9%) and ORR (37%), respectively. On the other hand, ceritinib showed the highest rate of severe adverse events (60%). Conclusion Our analysis indicated that alectinib and lorlatinib might be associated with the best therapeutic efficacy in first-line treatment for major population of advanced NSCLC patients with ALK-rearrangement. However, since there is little comparative evidence on the treatment options, there is need for relative trials to fully determine the best treatment options as well as the rapidly evolving treatment landscape.
