TPS8613 Background: Lurbinectedin is a novel synthetic chemical entity that acts as an inhibitor of oncogenic transcription and is active in tumors addicted to transcription. A phase II Basket trial (NCT02454972) in patients with small cell lung cancer (SCLC) treated with lurbinectedin in the second-line setting showed overall response rate (ORR) of 35.2% and median duration of response (DoR) of 5.3 months, with durable responses (43.0% ≥ 6 months). Based on these results, lurbinectedin was granted accelerated approval by the US FDA. An ongoing phase I/II trial (NCT02611024) is evaluating the lurbinectedin/irinotecan combination. Preliminary results showed ORR of 62% and median DoR of 5.7 months (2020 World Conference on Lung Cancer) warranting expansion to 100 patients. These results have supported the conduction of a phase III trial (LAGOON - NCT05153239). Methods: LAGOON is a randomized phase III clinical trial evaluating two experimental arms (lurbinectedin alone, 3.2 mg/m2 D1 q3wk, or lurbinectedin 2 mg/m2 D1 plus irinotecan D1, D8 q3wk) versus Investigator’s Choice (topotecan D1-5 q3wk or irinotecan D1 q3wk according to label) as control arm in relapsed SCLC patients. Approximately 705 patients will be enrolled. Central randomization will be implemented (1:1:1 ratio). Stratification will be done according to chemotherapy-free interval (CTFI) after first line (sensitive vs. resistant); prior anti-PD-(L)1; baseline central nervous system (CNS) involvement; lactate dehydrogenase value, and Investigator’s preference for the Control Arm. Main inclusion criteria include age ≥ 18 years, confirmed SCLC diagnosis, one prior line of platinum-containing chemotherapy with/without anti-PD-(L)1, and CTFI ≥ 30 days. Patients with CNS metastases can participate if pretreated and radiologically stable for at least 4 weeks. Main exclusion criteria include platinum-naïve patients, patients pretreated with more than one prior chemotherapy regimen (including platinum re-challenge), and prior treatment with lurbinectedin, trabectedin, PM14, or topoisomerase I inhibitors. An Independent Data Monitoring Committee will oversee the conduct of the study. An Independent Review Committee will provide the patient’s response at each tumor assessment endpoint to determine the best patient’s response and the date of objective response or progression/censoring according to RECIST v.1.1. Clinical trial information: NCT05153239 .

TPS8616 Background: Pleural metastases are common sites for recurrence and progression in patients with thymic malignancies. The management of pleural metastases typically involves surgical resection with or without neoadjuvant or adjuvant systemic therapy. After surgical resection of pleural metastases, the 5-year progression-free survival (PFS) rate is about 29-45%. While radiation therapy (RT) is standardly used in the management of locally-advanced thymic malignancies, the role of RT in patients with pleural metastases in unclear. Intensity-modulated pleural radiation therapy (IMPRINT) is a RT technique currently being used to treat malignant pleural mesothelioma (MPM) patients with 2 intact lungs at centers that specialize in MPM treatment. This IMPRINT technique can potentially be extrapolated to thymic patients with pleural metastases. Because the risk of toxicity is of greater concern for thymic patients given their overall relatively favorable prognosis, the rate of toxicity, particularly radiation pneumonitis, needs to be established in the thymic patient population. Methods: This is a single-arm, single institution Phase II study of hemithoracic IMPRINT for patients with pleural metastases from thymic malignancies. The primary endpoint of this study is grade 3 or higher radiation pneumonitis within 4 months of completing RT. Secondary endpoints include any toxicity, progression-free survival, patterns of failure and overall survival. Patients must have a pathologically confirmed diagnosis of a thymic malignancy with radiologic or pathologic evidence of pleural metastases. Thymoma or thymic carcinoma are allowed. Patients may have de novo stage IVA disease or recurrent disease in the pleura. There must be no evidence of extrathoracic metastatic disease or contralateral pleural/pericardial disease. Surgical resection of the pleural nodules (ex: pleurectomy/decortication, debulking/metastasectomy) are allowed. Extrapleural pneumonectomy is not allowed. Patients are excluded if they have undergone prior thoracic radiation therapy preventing hemithoracic pleural IMRT, whereas prior thymic bed radiation and/or prior pleural SBRT are allowed. RT will be administered to the ipsilateral pleura to 50.4 Gy in 28 fractions. An optional dose-painting boost to gross disease up to 60 Gy while respecting normal tissue constraints is allowed. Patients can be treated with photon or proton therapy. Simulation, contouring and RT planning guidelines have been developed. Patients will be followed per protocol at regular intervals for at least 12 months following RT. The expected accrual is 36 patients over 4 years.

Published: June 2023

TPS9150 Background: Detection of EGFR ctDNA after several weeks EGFR-TKIs treatment was an effective method to identify prognosis of advanced EGFR mutant NSCLC patients. Patients with uncleared EGFR ctDNA had shorter progression-free survival (PFS) ( Mack PC et al; CCR 2022). However, whether they can benefit from EGFR-TKI combination therapy has not been reported. Furmonertinib (AST2818), a potent, orally bioavailable, highly brain penetrant, third generation EGFR-TKI with unique chemical structure designed to improve potency and specificity, showed superior efficacy compared with gefitinib as first-line therapy in EGFR mutant NSCLC along with an acceptable safety profile without new signals ( Shi, YK et al.; Lancet Respir Med 2022). We hypothesized that monitoring clearance of EGFR ctDNA in blood could rationally guide subsequent monotherapy or combination therapy with furmonertinib and will improve outcomes in patients with uncleared EGFR ctDNA. Methods: The FOCUS-C study is a multicenter, open-label, randomized study. Patients who are aged 18 years or older and have histologically confirmed, locally advanced or metastatic, stage IIIB, IIIC, or IV unresectable NSCLC with EGFR exon 19 deletions (19Del) or exon 21 Leu858Arg mutation (L858R) on tissue biopsy and plasma will be treated with furmonertinib. Eligible patients with uncleared EGFR 19Del or L858R ctDNA after 3 weeks furmonertinib treatment will be stratified according to EGFR mutation (19Del or L858R), central nervous system metastases (with or without) and detectable accompanying gene aberrances in plasma (with or without) and randomly assigned (2: 2: 1) to receive furmonertinib or furmonertinib plus chemotherapy (pemetrexed and carboplatin for 4 cycles followed by maintenance pemetrexed) or furmonertinib plus chemotherapy plus bevacizumab (pemetrexed, carboplatin and bevacizumab for 4 cycles followed by maintenance pemetrexed and bevacizumab) in 21-day cycles until disease progression, the occurrence of intolerable toxicities, withdrawal of consent, or other discontinuation reasons judged by the investigators. The primary endpoint is PFS between furmoneritnib plus chemotherapy versus furmonertinib alone. Secondary endpoints include PFS, objective response rate, duration of response, disease control rate, overall survival and safety. Several exploratory endpoints will also be evaluated based on ctDNA detection by next-generation sequencing (Genecast, Wuxi, China). The study is enrolling. 34 patients had been enrolled till 2nd Feb 2023. Clinical trial information: NCT05334277 .

TPS9151 Background: First-line combination chemotherapy with pembrolizumab followed by maintenance pembrolizumab is the standard of care treatment for patients with metastatic sqNSCLC. This was established by the phase III KEYNOTE-407 trial, which demonstrated a median progression-free survival (PFS) of 6.4 months in the experimental arm. Despite these advances, there remains a need to continue to improve upon survival outcomes for these patients. Cabozantinib is a small-molecule inhibitor of multiple tyrosine kinsases including MET, VEGFRs, AXL, RET, and ROS, which are receptors involved in tumor cell-proliferation, angiogenesis, and immune cell regulation. Preclinical studies have demonstrated the ability of cabozantinib to modulate both adaptive and innate immune cells and to exhibit synergistic activity when used in combination with immune checkpoint inhibitors. We hypothesize that cabozantinib in combination with pembrolizumab in the maintenance phase of first-line treatment of metastatic sqNSCLC will prolong median PFS with a tolerable toxicity profile. Methods: LUNG-IST 127 is a pilot phase II, single-arm clinical trial of maintenance cabozantinib in combination with pembrolizumab for patients with metastatic sqNSCLC who achieved disease control following standard 1L induction therapy with chemotherapy and pembrolizumab. Thirty-six patients will be enrolled at 2 US sites to receive first-line induction therapy with carboplatin, nab-paclitaxel or paclitaxel, and pembrolizumab for four cycles. After induction therapy, those who have achieved disease control based on re-staging imaging will continue onto maintenance therapy with cabozantinib 40mg PO daily in combination with pembrolizumab 200mg IV every 3 weeks. The primary endpoint is PFS estimated by Kaplan-Meier methods with associated 95% confidence intervals. Based on an exploratory power analysis using an elevated one-sided alpha level of 0.40, we hypothesize that the proposed therapy will prolong median PFS from 6.4 to 9 months. Key secondary endpoints include overall survival (OS), overall response rate (ORR), and characterizing the safety and tolerability of cabozantinib in combination with pembrolizumab. Quality of life will also be measured with the EORTC QLQ-C30. Correlative endpoints include characterizing cfDNA from biofluids and assessing the change in circulating immune cells in different phases of treatment in association with PFS and OS. This trial would be the first to address whether there is clinical benefit in utilizing combination cabozantinib and pembrolizumab in the maintenance phase of treatment in metastatic sqNSCLC.

TPS9160 Background: The results of the FLAURA study established osimertinib as the new first-line standard of care for patients with the two ‘common’ types of epidermal growth factor receptor mutation-positive (EGFR+) advanced non-small-cell lung cancer (aNSCLC). Second-line (2L) treatment is typically platinum pemetrexed chemotherapy and the standard third-line (3L) treatment is docetaxel throughout much of the globe, which has a modest response rate of 7 – 15%. Previously, when first generation (1G) EGFR tyrosine kinase inhibitor (TKIs) were standard of care in the first-line setting, a number of prospective and retrospective studies examined 3L rechallenge with the same 1G EGFR TKI following 2L chemotherapy, with varying levels of success. Osimertinib is a well-tolerated EGFR TKI which is active against the T790M resistance mutation, which would have limited the efficacy of rechallenge with 1G EGFR TKIs. Methods: This is a multicentered international phase II investigator-initiated study of osimertinib in the 3L rechallenge of patients with EGFR+ aNSCLC, following 1L treatment with osimertinib and 2L therapy with platinum pemetrexed chemotherapy. A maximum of 255 patients will be enrolled. Patients with ‘common’ EGFR exon 19 deletions or L858R mutations will enroll at the start of 2L chemotherapy or 3L osimertinib rechallenge. The primary objective is 3L objective response rate (ORR) in the first 100 evaluable patients, according to RECIST 1.1. Secondary objectives include disease control rate (DCR), progression free survival (PFS), time to treatment failure, overall survival and toxicity for 3L osimertinib rechallenge. Exploratory objectives include assessment of osimertinib resistance based on serial ctDNA samples collected from all participants. The OCELOT study, NCT04335292, is actively enrolling participants.

Camrelizumab combined with anlotinib and nab-paclitaxel in patients with untreated advanced mucosal melanoma: A single-arm, multicenter, exploratory study.
Authors: Wu Di 
Published: June 2023

TPS9593 Background: Anti-programed cell death-1 (PD-1) monotherapy is a part of the standard treatment for cutaneous melanoma, but its efficacy in mucosal melanoma is not ideal. In vivo studies have demonstrated that co-inhibition of the VEGF receptor (VEGFR) and PD-1 pathways increased T cell infiltration and suppressed tumor growth synergistically. Early phase trial data confirmed that PD-1 inhibitors combined with anti-angiogenic drugs showed efficacy in the treatment of advanced mucosal melanoma, but still did not meet clinical needs. Previous studies have shown that chemotherapy combined with anti-angiogenic drugs has significantly improved median PFS and median OS compared with chemotherapy alone, and has a certain effect as a salvage treatment for progression after PD-1 inhibitor treatment. In addition, previous retrospective analysis showed that PD-1 inhibitors combined with chemotherapy drugs such as nab-paclitaxel were superior to anti-PD-1 monotherapy in the treatment of advanced mucosal melanoma. In summary, the combination of anti-PD-1, anti-angiogenic drugs and chemotherapy may bring new hope for the treatment of advanced mucosal melanoma. Methods: This is a single-arm, multicenter, exploratory study to evaluate the efficacy and safety of camrelizumab combined with anlotinib and nab-paclitaxel as first-line therapy in patients with advanced mucosal melanoma. The trial is expected to enrol 66 patients. Key Inclusion Criteria are pts with confirmed recurrence, unresectable or metastatic mucosal melanoma after surgery (stage III/IV) and ECOG performance status of ≤1.Pts with previous adjuvant therapy or neoadjuvant therapy (except PD-1/PDL1 monoclonal antibody and VEGFR TKI) at least 4 weeks before the first administration of the study drug are allowed. Patients received intravenous camrelizumab (200 mg) on day 1, intravenous nab-paclitaxel (260mg/m2) on day 1, and oral anlotinib (8mg) on days 1-14 every 3 weeks. The primary endpoint is objective response rate (ORR). Secondary endpoints include disease control rate (DCR),progression-free survival (PFS), and 2-year overall survival (OS).

Phase Ib/II study of XmAb23104 (PD1 X ICOS) and XmAb22841 (CTLA-4 X LAG3) combination in metastatic melanoma refractory to prior immune checkpoint inhibitor therapy with and without CNS disease.
Authors: Jacob Saya , Daud Adil 
Published: June 2023

TPS9595 Background: Immune checkpoint inhibitors (ICI) have greatly improved outcomes for patients by targeting programmed cell death protein 1 (PD1), cytotoxic T-lymphocyte–associated antigen 4 (CTLA4) and Lymphocyte Activation Gene-3 (LAG-3) to increase immune-mediated anti-tumor response. Despite these advances, ~50% of patients with metastatic melanoma do not respond to standard of care ICI. We strive to address this unmet clinical need through a Phase Ib/II, first-in-human, multi-center trial of two bispecific antibodies targeting four different immune checkpoints: XmAb23104 (PD1 X ICOS) and XmAb22841 (CTLA-4 X LAG3) in patients with melanoma refractory to ICI. This is the first trial of quadruple checkpoint inhibitor therapy. Furthermore, bispecific antibodies may allow simultaneous checkpoint blockade on the same cell and have been shown to heighten T cell activation in pre-clinical models. Two ongoing phase I trials of these bispecific antibodies with PD1 therapy have observed an immune related adverse event (irAE) rate of 20-24% with efficacy analysis ongoing (NCT03752398; NCT03849469). We postulate that treatment with XmAb23104 and XmAb22841 will enhance immune activation, overcome resistance, and improve disease control for patients refractory to traditional ICI. Methods: Eligible patients must have advanced/metastatic melanoma and have progressed on prior PD1/PD-L1 inhibitor or PD1/CTLA4 dual inhibition. Cutaneous, acral, mucosal and melanoma of unknown origin are allowed. Patient with CNS metastasis are allowed if these are asymptomatic and stable on MRI imaging obtained within 4 weeks of enrollment. Patients with prior unresolved irAE or irAE ≥ grade 3 are not allowed. XmAb23104 and XmAb22841 will be given on D1 and D15 of a 28-day cycle for 4 cycles, after which XmAb23104 (PD1 X ICOS) will be given alone for a total of 2 years. The phase I portion will be a dose escalation using standard 3+3 design of XmAb22841 (CTLA-4 X LAG3) with three dose levels (0.3 mg/kg, 1 mg/kg and 3 mg/kg). The dose of XmAb23104 (PD1 X ICOS) will remain at 10 mg/kg. These doses were selected based on results of prior early phase trials when these agents were combined with PD1. Once the P2RD of XmAb22841 (CTLA-4 X LAG3) is established, we will move on to dose escalation using a Simon’s 2-stage design. This portion will include two arms: Arm A consisting of 17 patients without CNS disease and Arm B consisting of 17 patients with CNS disease (total 34). Primary endpoints include dose limiting toxicities (DLT)/irAE and Objective Response Rate (ORR) at the time of best response by RECIST 1.1. Secondary endpoints include progression-free survival, overall survival, CNS response. At the time of this abstract submission, Cohort 1 of dose escalation has begun with the first few patients still within the DLT observation window. Clinical trial information: NCT05695898 .
Phase II study of niraparib in patients with advanced melanoma with genetic homologous recombination (HR) mutation/alteration.
Authors: Kim Kevin B. 
Published: June 2023

TPS9596 Background: There are a limited number of therapeutic options available for metastatic melanoma patients progressing on the checkpoint inhibitor(s) and BRAF-targeting drugs. PARP inhibitors have been approved in the setting of BRCA1/2 germline mutations, and have demonstrated activity in the setting of HR deficiency in other cancers. Documentation of PARP inhibitors in melanoma would have clear clinical impact. We have previously shown that 21-34% of metastatic melanomas harbor at least 1 molecular aberration in the HR pathway, considered pathogenic, and likely leading to HR deficiency. Previously, we demonstrated dramatic regression of tumors harboring HR mutation(s) with PARP inhibitor treatment in a PDX model. These findings provide a strong rationale to evaluate the clinical efficacy of a PARP inhibitor in patients with advanced melanoma with HR deficiency. Methods: This is a single arm, open-label, multi-center phase II trial. The primary objective of the study is: To evaluate the clinical efficacy of niraparib in advanced melanoma patients with HR deficiency. The secondary objectives is to evaluate PFS, OS, and safety profile of niraparib. The key eligibility criteria: Advanced melanoma patients with mutation in any of the following: ARID1A/B, ARID2, ATM, ATR, ATRX, BARD1, BRCA1/2, BAP1, BRIP1, CHEK2, FANCD2, MRN11A, RAD50, RAD51, RAD54B, PALB2 (requires a genetic analysis result performed at any CLIA-certified laboratory) disease progression on PD1-antibody therapy and if BRAF mutant, BRAF/MEK inhibitors ≥ 18 years of age; ECOG PS ≤ 1; prior systemic cytotoxic therapy ≤1 regimen; no limit on number of prior immunotherapy or targeted therapy regimens. No symptomatic brain metastasis; active brain lesions ≥6 mm size, or requiring steroid treatment Patients will be treated with oral niraparib once daily (28-day cycle); the dose will be 300 mg (if weight ≥77 kg and platelet counts of ≥150,000 µL); otherwise 200 mg RECIST 1.1 will be used to evaluate clinical response every 8 weeks. Adverse events will be recorded according to CTCAE version 4.03. The primary study endpoint is overall response rate. Simon’s optimal 2-stage design is proposed. With significance level of5% and 80% power, our null hypothesis that the true response rate is 0.10 will be tested against a one-sided alternative: H0: p ≤ 10%, a response rate of no real interest VS H1: p ≥ 30%, a response rate that would be of considerable interest 10 patients will be analyzed for a response evaluation in the first stage of the study, and 19 in the second stage, for a total of 29 patients. If the response rate is 10% (1/10) or less at the end of the first stage, further accrual will be terminated. With 2 or more responses in the first stage, accrual will continue to a total of 29 patients for this cohort. The null hypothesis will be rejected if ≥6 responses are observed in a cohort of 29 subjects. Clinical trial information: NCT03925350 .
