    Abstract: TPS3170 Background: Oncogenic mutations in myeloid differentiation primary response 88 (MYD88) occur in approximately 25% of diffuse large B-cell lymphoma (DLBCL) cases, including approximately 30% of activated B-cell DLBCL and up to 70% of primary extranodal DLBCL, and are associated with poor survival following 1 st line therapy. MYD88 mutations result in activation of the NF-κB pathway which drive a range of pro-tumor activities including upregulation of proinflammatory cytokines and genes involved in tumor cell proliferation and survival. Activation of this pathway results in upregulation of IRF4 through the transcription factors Ikaros and Aiolos, which in turn further augments NF-kB activation while simultaneously downregulating Type I IFN signaling, thereby preventing oncogene-induced cell death. Constitutive NF-kB pathway activation resulting from MYD88 mutations is dependent on the interleukin-1 receptor associated kinase 4 (IRAK4), a key component of the myddosome complex which normally stimulates NF-kB signaling following TLR or IL-1R engagement and MYD88 activation. KT-413 is a potent and selective heterobifunctional small molecule protein degrader mediating the degradation of both IRAK4 and the IMiD substrates Ikaros and Aiolos via the ubiquitin-proteasome system. The therapeutic hypothesis is that degradation of IRAK4 and IMiD substrates will maximize NF-κB inhibition while simultaneously upregulating the Type I Interferon response, thus restoring the apoptotic response and enabling oncogene-mediated cell death, resulting in robust antitumor response in MYD88-mutant DLBCL. KT-413 induced strong antitumor activity, including complete or partial regressions, in cell line- and patient-derived xenograft models of MYD88 MT DLBCL (Mayo 2021). Methods: KT-413 is being evaluated in an open label, dose escalation (Phase 1a) study in patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL), followed by dose expansion (Phase 1b) in patients with R/R DLBCL with documented tumor MYD88 mutation status. All patients must be ineligible or refused auto-SCT or CAR-T therapy. The Phase 1a (n = 40) utilizes an accelerated titration followed by a 3+3 design in ascending doses of IV administered KT-413 in once every 21-day cycles to identify the maximum tolerated dose (MTD)/recommended Phase 2 dose (RP2D) (primary endpoint). Secondary endpoints include pharmacokinetics (PK) and preliminary pharmacodynamic effects (PD) using blood and tumor tissue. Once MTD/RP2D is determined in 3-6 patients, it will be confirmed by enrolling additional patients with B-cell NHL, for a total of nine. In Phase 1b, up to 40 R/R DLBCL patients will be enrolled into one of two cohorts (n = 20): MYD88 MT or MYD88 WT to further characterize tolerability, PK, PD and evaluate the clinical activity of KT-413. KT413-DL-101 began enrollment in February 2022. Clinical trial information: NCT05233033.

    Abstract: 4001 Background: BEACON CRC is a randomized, phase 3 study which evaluated the triplet of encorafenib (ENCO) + binimetinib (BINI) + cetuximab (CETUX) and the doublet of ENCO + CETUX vs. investigator’s choice of irinotecan + CETUX or FOLFIRI + CETUX in patients (pts) with BRAFV600E metastatic colorectal cancer (mCRC) whose disease had progressed after 1-2 prior regimens in the metastatic setting. Primary endpoints were overall survival (OS) and objective response rate (ORR; by blinded central review) for triplet vs control. In a previous interim analysis, triplet and doublet improved OS and ORR versus standard of care. Here we report on an updated analysis. Methods: Updated analysis includes 6 months of additional follow-up and response data for all randomized pts. The study is ongoing. Results: Pts received triplet (n=224), doublet (n=220), or control (n=221). Median OS was 9.3 months (95% confidence interval [CI]:8.2, 10.8) for triplet and 5.9 months (95% CI:5.1-7.1) for control (hazard ratio [HR] (95% CI): 0.60 (0.47-0.75)). Median OS for doublet was 9.3 months (95% CI: 8.0-11.3) (HR vs. control: 0.61 (0.48-0.77). Confirmed ORR was 26.8% (95% CI: 21.1%-33.1%) for triplet, 19.5% (95% CI: 14.5%-25.4%) for doublet, and 1.8% (95% CI: 0.5%-4.6%) for control. Retrospective subgroup analyses suggested some pts may benefit more from triplet than doublet therapy (Table). Both triplet and doublet showed improved OS compared to control in all subgroups. Adverse events were consistent with prior analysis, with grade ≥3 adverse events in 65.8%, 57.4%, and 64.2% for triplet, doublet and control, respectively. Conclusions: The updated analysis of the BEACON CRC study confirmed that encorafenib + cetuximab with or without binimetinib improved OS and ORR in previously treated pts with BRAF V600E mCRC compared with standard chemotherapy.

    Abstract: TPS3110 Background: CSF1, which signals via CSF1R, regulates tumor-associated macrophages and myeloid-derived suppressor cells, both critical drivers of immune escape in the tumor microenvironment. ARRY-382 is a highly selective, oral inhibitor of the CSF1R intracellular tyrosine kinase. The first-in-human study of ARRY-382 monotherapy identified the maximum tolerated dose (MTD) of 400 mg QD, with biologic activity at doses ≥200 mg QD (Bendell JC et al. Mol Cancer Ther. 2013;12:A252). Preclinical data supports combining a PD-1 inhibitor with a CSF1R inhibitor (Zhu Y et al. Cancer Res. 2014;74:5057-69). This study is designed to evaluate ARRY-382 in combination with pembro, a potent and highly selective humanized monoclonal antibody that targets PD-1. Methods: This is an open-label, multicenter, phase 1b/2 study (NCT02880371) to determine the MTD and/or recommended phase 2 dose (RP2D) of ARRY-382 + pembro and to evaluate the activity of the combination in select indications. In phase 1b (Part A), the primary objective is to identify the MTD/RP2D. Up to 18 pts with select advanced solid tumors (Part A) will be enrolled in 2 successive cohorts evaluating ARRY-382 at doses of 200 mg QD and 400 mg QD, respectively, in combination with pembro 2 mg/kg Q3W. Once the MTD/RP2D has been determined in phase 1b, phase 2 will concurrently evaluate the combination in up to 20 pts with advanced unresectable/metastatic melanoma (Part B) and in up to 33 pts with PD-L1-positive (tumor proportion score ≥50) non-small cell lung cancer (NSCLC) (Part C). The primary objective of Part B is to assess the pharmacodynamics and antitumor activity of ARRY-382 + pembro in pts with advanced unresectable/metastatic melanoma, and the endpoints include effects of treatment on circulating growth factors and cytokines, markers of bone resorption, and objective response rate (ORR). The primary objective of Part C is to assess the efficacy of ARRY-382 + pembro in pts with PD-L1–positive NSCLC (Part C). The primary endpoint is ORR. Immune-related response rate and safety will be evaluated in all pts in the study. Clinical trial information: NCT02880371.

    Abstract: 9518 Background: The benefits of BRAF + MEK inhibition (dual combo) in pts with BRAF V600-mutant ( BRAF V600 ) melanoma are known. Preclinical data supports inhibiting CDK 4/6 and BRAF + MEK (triple combo) to improve antitumor activity. We report safety and preliminary efficacy from a phase 1b/2 study (NCT01543698) of encorafenib (ENCO; a selective BRAF kinase inhibitor), binimetinib (BINI; a MEK inhibitor), and ribociclib (RIBO; a CDK 4/6 inhibitor). Methods: Phase 1b of this open-label, multicenter study enrolled pts with confirmed BRAF V600 advanced solid tumors. Escalating doses of RIBO 100 mg-600 mg QD for 3 wk on/1 wk off were administered with ENCO 200 mg QD + BINI 45 mg BID in successive cohorts (6 pts each) until the maximum tolerated or recommended phase 2 dose (RP2D) was reached. Due to potential pharmacokinetic interactions with RIBO, the ENCO dose was lower than the dual combo RP2D (450 mg QD). Dose escalations followed an adaptive Bayesian model. In phase 2, the triple combo was tested in pts with BRAF V600 melanoma naïve to prior BRAF inhibitor treatment; the primary endpoint was objective response rate (ORR) per RECIST v1.1. Results: In phase 1b (n = 21), no dose-limiting toxicities were reported and the triple combo RP2D was ENCO 200 mg QD + BINI 45 mg BID + RIBO 600 mg QD. ENCO AUC was slightly lower than at the dual combo RP2D. In phase 2 (n = 42), 59.5% pts had an ECOG PS of 0 and 43% of pts had elevated lactate dehydrogenase. The most common (≥5%) grade 3/4 toxicities were neutropenia (26.2%), increased alanine transaminase (14.3%), diarrhea (7.1%), and anemia (7.1%). Ten pts (23.8%) discontinued treatment due to an AE, of which 4 were increased transaminases. The confirmed ORR was 52.4%, including 4 complete responses, 18 partial responses, and 15 pts with stable disease. Median duration of exposure in phase 2 was 9.1 mo (range, 0.0-21.6). Median progression-free survival was 9.0 mo (95% confidence interval, 7.0-11.1). Conclusions: Triple therapy with ENCO + BINI + RIBO in this small trial of pts with high disease burden was associated with responses in over half of pts and some evidence of increased toxicity. Clinical trial information: NCT01543698.

    Abstract: To determine the safety and preliminary efficacy of selective combination targeted therapy for BRAF V600E–mutant metastatic colorectal cancer (mCRC) in the safety lead-in phase of the open-label, randomized, three-arm, phase III BEACON Colorectal Cancer trial ( ClinicalTrials.gov identifier: NCT02928224; European Union Clinical Trials Register identifier: EudraCT2015-005805-35). PATIENTS AND METHODS Before initiation of the randomized portion of the BEACON Colorectal Cancer trial, 30 patients with BRAF V600E–mutant mCRC who had experienced treatment failure with one or two prior regimens were to be recruited to a safety lead-in of encorafenib 300 mg daily, binimetinib 45 mg twice daily, plus standard weekly cetuximab. The primary end point was safety, including the incidence of dose-limiting toxicities. Efficacy end points included overall response rate, progression-free survival, and overall survival. RESULTS Among the 30 treated patients, dose-limiting toxicities occurred in five patients and included serous retinopathy (n = 2), reversible decreased left ventricular ejection fraction (n = 1), and cetuximab-related infusion reactions (n = 2). The most common grade 3 or 4 adverse events were fatigue (13%), anemia (10%), increased creatine phosphokinase (10%), increased AST (10%), and urinary tract infections (10%). In 29 patients with BRAF V600E–mutant tumors (one patient had a non– BRAF V600E–mutant tumor and was not included in the efficacy analysis), the confirmed overall response rate was 48% (95% CI, 29.4% to 67.5%), median progression-free survival was 8.0 months (95% CI, 5.6 to 9.3 months), and median overall survival was 15.3 months (95% CI, 9.6 months to not reached), with median duration of follow-up of 18.2 months (range, 16.6 to 19.8 months). CONCLUSION In the safety lead-in, the safety and tolerability of the encorafenib, binimetinib, and cetuximab regimen is manageable and acceptable for initiation of the randomized portion of the study. The observed efficacy is promising compared with available therapies and, if confirmed in the randomized portion of the trial, could establish this regimen as a new standard of care for previously treated BRAF V600E–mutant mCRC.

    Abstract: 2533 Background: PF-04856884 is a recombinant humanized monoclonal antibody fused to two Ang-2 binding peptides. Axitinib is a potent and selective second-generation inhibitor of vascular endothelial growth factors (VEGFs) that is approved for patients (pts) with advanced renal cell cancer who failed 1 prior therapy. Metastatic RCC (mRCC) is an angiogenic tumor sensitive to VEGF tyrosine kinase inhibitors. Resistance to VEGF targeted therapy may be mediated by Ang-2. Methods: In Part I (safety lead in) of the study, the primary endpoint was treatment related dose limiting toxicities (DLT) in pts with mRCC who had received 1-3 prior treatments. Pts received PF-04856884 (15 mg/kg/week) plus axitinib (5 mg BID) for 4 week cycles (the recommended Phase II dose of each) and were assessed for DLT, PK, and potential predictive biomarkers (Ang-2 and VEGF-A). For Part II (Phase II portion), pts with mRCC who had received 1 prior anti-VEGF agent were to be randomized to PF-04856884 + axitinib or axitinib alone to assess median progression free survival. Results: Part I enrolled 18 pts with median age of 62.5 years (39-82), and ECOG performance status of 0-1. One pt had a DLT of Grade 4 pulmonary embolism (PE). Most common related AEs: anorexia in 10 pts (56%), diarrhea 8 (44%), fatigue 8 (44%), nausea 7 (39%), hypertension 6 (33%) and vomiting 6 (33%). Treatment-related thromboembolic events (TEEs) were observed: PE in 2 pts (11%), and cerebrovascular accident (CVA), presumed bowel ischemia, and possible cardiac chest pain in 1 pt (6%) each. One pt had Grade 2 venous thrombosis unrelated to either treatment. Due to the reported TEE, PF-04856884 was reduced to 10 mg/kg in pts remaining on study and enrollment to Part II was not initiated. No significant PK interaction was observed. Two pts had partial response (PR) and 1 pt had unconfirmed PR. Twelve pts (66%) remained on study ≥91 days with a median duration of 120 days (8-279). Anti-PF-04856884 antibody results are not available. Conclusions: Due to the higher than expected TEEs, alternate doses of PF-04856884 and/or disease settings are being considered. Clinical trial information: NCT01441414.

    Abstract: 3513 Background: Encorafenib + binimetinib + cetuximab (enco/bini/cetux; triplet) and enco + cetux (doublet) regimens improved overall survival and objective response rate vs standard of care in pts with previously treated BRAF V600E-mutant mCRC in the randomized phase 3 BEACON study. To identify molecular correlates of clinical outcome, we performed molecular profiling in tumors from pts in the study. Methods: Baseline tumor samples were retrospectively analyzed by whole-exome sequencing (WES) and whole transcriptome sequencing (WTS) using ImmunoID NeXT (Personalis, Menlo Park, CA, USA). BRAF-mutant (BM) and consensus molecular subtypes (CMS) were determined using published classifiers. Pathway activities were evaluated with gene set variation analysis. Objective tumor response was evaluated according to each subtype. Additional association and interaction analyses between molecular features and clinical outcomes by treatments are ongoing and will be presented. Results: Baseline tumor samples were analyzed by WES and/or WTS from 527 of 665 (79.2%) randomized pts. The biomarker analyses set is representative of the total pt population and had similar clinical outcomes. Of the 460 pts analyzed by WTS (165/224 [73.7%] in the triplet arm, 146/220 [66.4%] in the doublet arm, and 149/221 [67.4%] in the control arm), 84.6% were classified as either CMS1 (n = 225) or CMS4 (n = 164). The proportion of pts classified as BM1 was 32.2% (n = 148) and the majority (84.5%) of these were CMS4, whereas many of those classified as BM2 (67.8%, n = 312) were CMS1 (64.7%). In the BM1 and CMS4 tumors, expression of inflammatory response and epithelial mesenchymal transition genes were elevated, and expression of cell cycle genes was reduced. The response rate in pts with CMS4 and/or BM1 tumors was higher in the triplet arm (CMS4: 33.3% [95% CI: 21.7–46.7] ; BM1: 33.3% [95% CI: 21.4–47.1]) compared with the doublet arm (CMS4: 19.2% [95% CI: 9.6–32.5] ; BM1: 14.9% [95% CI: 6.2–28.3]). Conclusions: Molecular characteristics and biological properties observed in BRAF V600E-mutant mCRC suggest that a subset of pts with specific molecular features may derive greater clinical benefit from triplet than doublet therapy. Additionally, these findings support the utility of gaining further understanding of the biological landscape in BRAF-mutant mCRC to enable potential hypotheses for pt selection to improve clinical outcome in future studies. Clinical trial information: NCT02928224.

    Abstract: The prognosis for patients with chronic myeloid leukemia (CML) in myeloid blast crisis (MBC) or lymphoid blast crisis (LBC) remains poor. Although imatinib can induce responses in a subset of these patients, resistance to the drug develops rapidly. Dasatinib is a novel, oral, multitargeted kinase inhibitor of BCR-ABL and SRC family kinases. After promising phase 1 results, we report the results of phase 2 clinical trials of dasatinib in patients with imatinib-resistant or -intolerant blast crisis CML (MBC, n = 74; LBC, n = 42). At the 8-month follow-up, dasatinib induced major hematologic responses (MaHRs) in 34% and 31% of MBC- and LBC-CML patients and major cytogenetic responses (MCyRs) in 31% and 50% of these patients, respectively. Most (86%) of these MCyRs were complete cytogenetic responses (CCyRs). Responses were rapid and durable: 88% and 46%, respectively, of MBC- and LBC-CML patients achieving MaHR had not experienced disease progression at the 8-month follow-up. Response rates were similar in patients with and without BCR-ABL mutations known to confer resistance to imatinib. Dasatinib was well tolerated. Nonhematologic adverse events were mild to moderate. Cytopenias were common and could be managed by dose modification. Dasatinib is highly active and produces hematologic and cytogenetic responses in a significant number of patients with imatinib-resistant or -intolerant MBC- and LBC-CML. These trials were registered at www.clinicaltrials.gov as #CA180006 and #CA180015.

    Abstract: Treatment options are limited for patients with imatinib-resistant or -intolerant accelerated phase chronic myeloid leukemia (CML-AP). Dasatinib is a novel, potent, oral, multitargeted kinase inhibitor of BCR-ABL and SRC-family kinases that showed marked efficacy in a phase 1 trial of patients with imatinib-resistant CML. Results are presented for 107 patients with CML-AP with imatinib-resistance or -intolerance from a phase 2, open-label study further evaluating dasatinib efficacy and safety. At 8 months' minimum follow-up, 81%, 64%, and 39% of patients achieved overall, major (MaHR), and complete hematologic responses, respectively, whereas 33% and 24% attained major and complete cytogenetic remission. Of 69 patients who achieved MaHR, 7 progressed. Seventy-six percent of patients are estimated to be alive and progression-free at 10 months. Response rates for the 60% of patients with baseline BCR-ABL mutations did not differ from the total population. Dasatinib was well tolerated: most nonhematologic adverse events (AEs) were mild to moderate; no imatinib-intolerant patients discontinued dasatinib because of AEs. Although common (76% of patients with severe neutropenia), cytopenias were manageable through dose modification. In summary, dasatinib induced significant hematologic and cytogenetic responses in patients with imatinib resistance or intolerance, was well tolerated, and may represent a potent new therapeutic option for CML-AP. Further follow-up is warranted. This trial was registered at www.clinicaltrials.gov as #CA180005.
