    Abstract: TPS2661 Background: Letetresgene autoleucel (lete-cel; GSK3377794) is an autologous T-cell therapy using a genetically modified T-cell receptor (TCR) to improve recognition of cancer cells expressing NY-ESO-1/LAGE-1a. Next generation NY-ESO-1 TCR T-cell therapies, such as GSK3901961 and GSK3845097, integrate added genetic modifications to enhance anticancer activity. GSK3901961 co-expresses the CD8α chain to stabilize TCR-human leukocyte A (HLA) class I interactions on CD4+ T cells, improving T-cell persistence and helper functions such as Type 1 T-helper antitumor responses. GSK3845097 co-expresses a dominant negative transforming growth factor-β (TGF-β) type II receptor to reduce TGF-β pathway activation and maintain T-cell proliferation, cytokine production, and cytotoxicity in the tumor microenvironment. A first-time-in-human master protocol (NCT04526509) will evaluate safety, tolerability, and recommended phase 2 dose (RP2D) of these and possible subsequent therapies. Substudy 1 will assess GSK3901961 in patients (pts) with advanced non-small cell lung cancer (NSCLC) or synovial sarcoma (SS). Substudy 2 will assess GSK3845097 in pts with advanced SS. Methods: Each substudy includes a dose confirmation stage to assess RP2D and a dose expansion stage. Key inclusion criteria are age ≥18 y; measurable disease per RECIST v1.1; HLA-A*02:01, A*02:05, or A*02:06 positivity; NY-ESO-1/LAGE-1a tumor expression; advanced (metastatic/unresectable) SS with t(X;18) translocation and anthracycline-based therapy receipt/completion/intolerance (SS only); and Stage IV NSCLC, receipt of ≥1 prior line(s) of standard of care (SOC) therapy including programmed death receptor- or ligand-1 inhibitors, and SOC chemotherapy receipt/intolerance (Substudy 1 only). Key exclusion criteria are prior malignancy that is not in complete remission or clinically significant systemic illness; prior receipt of gene/NY-ESO-1–specific therapy or allogenic stem cell/solid organ transplant; central nervous system metastases (SS only); and actionable genetic aberration and receipt/failure of ≥3 systemic therapy lines (Substudy 1 only). Primary endpoints are safety (adverse events) and tolerability (dose-limiting toxicities). Secondary endpoints include investigator-assessed overall response rate, duration of response, and maximum expansion/persistence and phenotype of infiltrating transduced T cells. Exploratory endpoints include laboratory parameters, overall survival, and anti-GSK3901961 or -GSK3845097 titers as applicable. Analyses will be descriptive. The substudies are enrolling.

    Abstract: Introduction: There is a high unmet medical need for patients with advanced non-small cell lung cancer (NSCLC) who have failed platinum-based chemotherapy and checkpoint inhibitors. Only 10% of such patients receive any benefit from current therapies, and novel therapies are needed to improve outcomes. Preclinical data support the efficacy, specificity and possible safety of NYESO1/LAGE1a T-cell receptor-engineered patient Tcells (GSK3377794) in NSCLC. Pembrolizumab (PEM) is a monoclonal antibody, which specifically blocks PD1/PDL1 interaction, thereby increasing the antitumor function of Tcells. Thus, the combination of GSK3377794 and PEM may work synergistically due to the inhibition of PD1/PD-L1 signaling on GSK3377794 and other T-cells, potentially further improving the therapeutic effect. Methods: This is a Phase Ib/IIa randomized, multiarm, openlabel pilot study (NCT03709706) in human leukocyte antigen (HLA)A*02:01, HLAA*02:05 and/or HLAA*02:06 adult patients (aged & gt;18 years) whose tumors express NYESO1 and/or LAGE1a. This study aims to enroll up to 44 patients with unresectable Stage IIIb or Stage IV NSCLC who were either ineligible for definitive chemoradiotherapy, have recurrent disease which has progressed during or after platinumbased chemotherapy with or without anti-PD-1 agents, have terminated prior treatment due to intolerable side effects, or have refused standard approved treatment. Patients will be randomized (1:1) to two treatment arms. Arm A will receive GSK3377794 as monotherapy, administered as a single intravenous (IV) infusion; Arm B will receive GSK3377794 as a single IV infusion on Day 1 followed by PEM 200 mg initiated on Day 22 and continued for up to 35 cycles or until disease progression. Patients in Arm A who progress after receiving GSK3377794 monotherapy will be offered antiPD1 therapy at the same dose and duration as Arm B. The study will use a Bayesian adaptive design, wherein enrollment can be halted in either arm for futility. The patient journey will consist of 3 parts: patients will undergo eligibility screening (Part 1), followed by leukapheresis (Part 2), after which patients will enter the Interventional Phase (Part 3) during which patients will receive preparative lymphodepleting chemotherapy followed by infusion of GSK3377794. The first patient was screened on December 31, 2018. ClinicalTrials.gov identifier: NCT03709706 Study is funded by GlaxoSmithKline and is in collaboration with Merck & Co., Inc.

A Phase Ib/IIa randomized pilot study to investigate the safety and tolerability of autologous T-cells with enhanced T-cell receptors specific to NY-ESO-1/LAGE-1a (GSK3377794) alone, or in combination with pembrolizumab, in advanced non-small cell lung cancer [abstract].

    Abstract: TPS3167 Background: Protein arginine methyltransferase 5 (PRMT5) is an emerging target for cancer treatment. MTAP homozygous deletion occurs in 15% of cancers and often coincides with deletion of the tumor suppressor gene CDKN2A, leading to buildup of its substrate MTA. MTA shares close structural similarity to S-adenosyl methionine (SAM), the substrate methyl donor for PRMT5. By competing with SAM, MTA partially inhibits PRMT5. Thus, MTAP-null cancers are susceptible to further PRMT5 inhibition (Kryukov Science 2016). Current direct/indirect PRMT5 inhibitors (PRMT5i) showed preliminary anticancer activity, albeit with considerable toxicities due to their indiscriminate activities. AMG 193 is an MTA-cooperative PRMT5i that preferentially targets the MTA-bound state of PRMT5 that is enriched in MTAP-null tumors and represents a novel strategy to increase the therapeutic margin of this class of inhibitors. AMG 193 potently inhibits MTAP-null cancer cell lines and patient-derived xenografts. Methods: NCT05094336 is a first-in-human (FIH), multicenter, open-label, phase 1/1b/2 trial evaluating the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and efficacy of AMG 193 in patients with advanced MTAP-null solid tumors. Eligible patients (≥ 18 years) with histologically confirmed locally advanced/metastatic solid tumors not amenable to curative treatment with surgery and/or radiation, homozygous MTAP and/or CDKN2A deletion (by local next generation sequencing), or MTAP protein loss in tumors (by central immunohistochemistry), measurable disease, ECOG PS 0‒1, adequate hematopoietic, renal, liver, pulmonary, cardiac, coagulation function and glucose control will be included. The study will be conducted in 3 parts, each with subparts. Here, we describe Part 1a/b (dose exploration). Five dose levels are planned. Treatment continues until progression or withdrawal. The primary objectives are to evaluate the safety and tolerability of AMG 193 monotherapy; endpoints include dose-limiting toxicities, treatment-emergent adverse events, serious adverse events, electrocardiograms, laboratory abnormalities, and vital signs. Secondary objectives include the characterization of the PK parameters of AMG 193 including C max , T max , and AUC after single or multiple doses. This study is expected to enroll approximately 30 patients in Part 1a/b. This is the first FIH trial open for enrollment for this new class of PRMT5i and enrollment is ongoing. Clinical trial information: NCT05094336.

    Abstract: The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded newinsight into brain cancer. However, the complete repertoire of signaling pathways that governs the proliferation and self-renewal of NSCs, which we refer to as the ‘ground state’, remains largely uncharacterized. Although the candidate gene approach has uncovered vital pathways in NSC biology, so far only a few highly studied pathways have been investigated. Based on the intimate relationship between NSC self-renewal and neurosphere proliferation,we undertook a chemical genetic screen for inhibitors of neurosphere proliferation in order to probe the operational circuitry of the NSC. The screen recovered small molecules known to affect neurotransmission pathways previously thought to operate primarily in the mature central nervous system; these compounds also had potent inhibitory effects on cultures enriched for brain cancer stem cells. These results suggest that clinically approved neuromodulators may remodel the mature central nervous system and find application in the treatment of brain cancer.

    Abstract: e14505 Background: Anti-tumor lymphocytes activated in response to ICIs may cross the blood brain barrier with effect on brain metastases (BM). Preliminary evidence suggests that ICIs alone are effective for melanoma BMs. However, the ability of ICI to effectively control NSCLC BMs without radiotherapy is controversial. By comparing serial MRIs and patterns of progression in ICI and chemotherapy treated patients, we sought to investigate the role of ICI in BM control in NSCLC patients. Methods: Serial MRIs were reviewed in ICI treated NSCLC patients with known BMs. Eligible patients must have a minimum of one baseline MRI and a follow-up within 3 months of CNS directed treatment. Patients with EGFR/ ALK mutations were excluded. A control cohort of patients who had never received ICIs was selected using the same criteria. The primary outcome was cumulative CNS progression and intracranial progression free survival (iPFS) analyzed using an accelerated failure time model and competing risk analysis. Results: We identified 137 ICI treated NSCLC patients with known BMs. After excluding for patients without serial MRIs, we analyzed 40 ICI treated patients and 39 controls. All patients received upfront radiotherapy or surgery and the modality used was similar (p = 0.13). CNS failure was less common in the ICI group (p = 0.02). ICI treated patients had a trend to longer iPFS in the PD-L1 ≥50% subgroup (p = 0.058). Cumulative incidence of progressive BM at 12 and 24 months were significantly lower in the ICI treated PD-L1 ≥50% subgroup: 19%/19% vs 50%/56% (p = 0.02). Patients in the PD-L1 ≥50% subgroup who achieved a systemic partial response (n = 10) did not experience any CNS events despite extracranial progression in some. Conclusions: Durable CNS disease control is observed with ICIs in NSCLC with PD-L1 ≥50% and demonstrates a high level of concordance with systemic response. The need for radiotherapy in PD-L1 ≥50% disease should be investigated and may be reasonably delayed in asymptomatic patients with small BMs. Importantly, the same trend was not observed in PDL1 〈 50% patients and caution is needed in employing this strategy in this subset of patients.

    Abstract: 5551 Background: Genomic characterization of mCRPC has identified commonly occurring alterations but also recurrently mutated genes at much lower frequencies. To efficiently evaluate anti-tumor activity of novel targeted therapies in mCRPC patients (pts) we initiated an umbrella trial using circulating tumour DNA (ctDNA) to enrich accrual for cancers with alterations that may predict response. Methods: mCRPC pts that have progressed after treatment with a next generation AR-pathway inhibitor (ARPI) were enrolled to this multi-center, multi-arm, 2-stage phase II trial. Plasma cell-free DNA was subjected to targeted sequencing and pts allocated to a treatment arm by a Tumor Board (TB) based on a priori criteria (biomarker positive, BM+) or by randomization if biomarker negative (BM-). Primary objective was to determine the clinical benefit rate (CBR: PSA decline ≥50% (PSA50), CR/PR, or stable disease ≥12 weeks). We report on 1st-stage activity of arms evaluating inhibitors of CDK4/6 (palbociclib), WEE1 kinase (adavosertib), cMET (savolitinib) and the AR inhibitor darolutamide. Additional planned arms include inhibitors of AKT (ipatasertib), Polo-like Kinase 4 (CFI-400945), immune checkpoints (durvalumab, tremelimumab) and carboplatin. Results: 250 pts were screened from two sequential trials over 29 months at 11 centers. Median time from blood draw to TB decision was 35 days. 169 pts (68%) had detectable ctDNA (≥1%) with a mean ctDNA fraction of 24% (range 1-95%). Commonly detected genomic alterations involved AR (49% gain, 24% mutation), TP53 (49%), PTEN/PI3K pathway (35%), DNA repair (23%: mismatch repair (5%), BRCA2 (8%), ATM (3%), CDK12 (5%), other (2%)) and CTNNB1/APC (14%). To date, 46 BM+ pts and 37 BM- patients were enrolled: median age 70 years (53-88), 100% had prior ARPI, 45% had prior docetaxel, 17% with visceral metastases. Accrual and CBR are presented in table. Adverse events were as expected. Conclusions: Prospective centralized screening of ctDNA to stratify mCRPC pts into a precision oncology trial is feasible. Activity was seen in 4 of 7 evaluable cohorts with darolutamide and adavosertib, meeting the threshold for expansion of these arms. Clinical trial information: NCT03385655, NCT02905318 .

    Abstract: e19306 Background: Recent advances in small cell lung cancer (SCLC) treatments necessitate a better understanding of health utility scores (HUS) of patients treated under standard regimens to facilitate robust pharmaco-economic assessments. HUS collected in clinical trials may be inherently skewed due to restrictive eligibility criteria, highlighting the need for real-world data. Methods: In this cohort observational study, HUS were evaluated in SCLC patients through EQ-5D surveys. We also evaluated patient reported (pr) ECOG performance status (PS)), treatment toxicities (modified patient reported (mpr) CTCAE) and symptoms (Edmonton Symptom Assessment System, ESAS). Clinical data were abstracted from electronic medical records. The impact of these variables on HUS was explored using regression. Results: Of 282 clinical encounters (12% newly diagnosed; 37% stable on treatment; 22% progressing; 29% stable off therapy/other) in 111 SCLC patients (58% male; 64% extensive stage), 29% had pr-ECOG PS ≥ 2 at the first encounter. Mean HUS in treatment naïve patients with limited disease was 0.848 (SEM = 0.028); for extensive stage, mean HUS = 0.715 (SEM = 0.046). Extensive stage (β = -0.12; p = 0.03), bone metastases (β = -0.10; p = 0.04), females (β = -0.07; p = 0.006), and pr-ECOG PS ≥ 2 (β = -0.21; p 〈 0.001) were each associated with decreased HUS in multivariable analyses. When excluding pr-ECOG PS from the model (highly correlated with HUS), progressive disease (β = -0.07; p = 0.02) was also associated with decreased HUS. Longitudinally, in patients with disease stability, HUS were unchanged in limited disease, but slowly decreased for extensive stage over time. HUS were inversely associated with increasing severity of most measured toxicities (mpr-CTCAE rho values ranged from -0.34 to -0.47) and symptoms (rho values -0.27 to -0.54). Conclusions: HUS in SCLC is impacted by the presence of extensive stage and bone metastases, in addition to cancer symptoms and treatment toxicities. The values reported from this real-world sample provides a basis in which to compare with new SCLC therapies in health technology assessments. [Table: see text]

    Abstract: 332 Background: Patients (pts) with mRCC with SD have unfavorable outcomes and poor prognosis due to aggressive tumor behavior. Chemotherapy and targeted treatment are often of little benefit. However, recent studies have shown a survival benefit of immunotherapy (IO). Here, we report survival outcomes of pts with mRCC with SD treated with first line IO or chemotherapy or targeted treatment. In addition we performed a meta-analysis of recent practice changing phase III, IO trials in mRCC. Methods: This retrospective survival analysis was performed in pts with mRCC with SD treated with IO or non-IO treatment at Princess Margaret Cancer Centre (PM), Toronto. Demographics, disease characteristics and survival outcomes were collected. Progression free survival (PFS), and overall survival (OS) were calculated using the Kaplan-Meier method (log-rank). PFS and OS hazard ratios (HR) were calculated using cox proportional hazards model. We identified the major, practice changing clinical trials that reported survival outcomes of mRCC with SD treated with IO and performed a random-effects meta-analysis of HR for PFS and OS. We compared these pooled results to our single institution experience. Results: We identified 474 pts diagnosed with mRCC at PM between 2002 and 2019. In total, 44 (9.3%) pts had mRCC with SD who were treated with IO or non-IO. Of these, 29 (65.9%) pts had pure SD and 15 (34.1%) pts had mixed rhabdoid and SD features. Median age was 59.6 years (36-78) and 33 (75%) were male. Overall, as per the IMDC score, 3(6.8%), 21(47.7%) and 20(45.5%) pts were categorized as good, intermediate, and poor risk, respectively. Eight (18.2%) pts were treated with IO as first line of treatment, and 36 (81.8%) pts received non-IO. With a median follow up of 64.8 months (range, 45.7-83.8 months), the median OS for the whole mRCC with SD cohort was 15.6 months (95% CI: 8.6-22.5). The median OS in all pts treated with IO vs non-IO was not reached vs 10.3 months (95%CI: 1.49-19.1 months; p = 0.005), respectively. The HR for OS was 0.1 (95%CI: 0.01-0.78; p = 0.023) favoring IO receipt. The median PFS in all pts treated with IO vs non-IO was 24 months (95%CI: non-estimable) vs 5.4 months (95%CI: 2.9-7.8 months; p = 0.021), respectively. The HR for PFS was 0.3 (95%CI: 0.11-0.89; p = 0.03) favoring IO receipt. We identified through meta-analysis five phase III clinical trials reporting PFS and OS in pts with mRCC with SD who received IO. The overall HR for OS and PFS for the total cohort were 0.55 (95%CI: 0.41-0.74), and 0.53 (95%CI: 0.42-0.67), respectively. Conclusions: Our meta-analysis has confirmed the benefit of IO agents in mRCC with SD. While the numbers included in this retrospective review were small, they have provided real world corroboration of the trial findings. Pts with mRCC and SD benefit from IO treatment, which should be considered the standard of care for these patients.
