e13599 Background: Simultaneous inhibition of both the PI3K-Akt and RAF/MEK/ERK pathways may yield greater benefits than inhibiting either pathway alone. This phase I study (NCT01021748) examined the safety, pharmacokinetics (PK), pharmacodynamics (PD), maximal tolerated dose (MTD), and preliminary antitumor activity of the combination of a MEKi (selumetinib) and AKTi (MK-2206). Methods: Eligible patients (pts) with advanced solid tumors were treated with MK-2206 either every other day (QOD) or once weekly (QW), in combination with selumetinib administered either once daily (QD) or twice daily (BID). Results: 51 pts with advanced solid tumors (15 colon, 8 NSCLC, 6 ovarian, 5 pancreatic, 3 breast and 14 others) were treated across 9 dose levels. There were 2 confirmed partial response (PR) (1 NSCLC, ongoing > 52 wks; 1 ovarian, on treatment for 47 weeks; both KRAS mutation positive), 1 unconfirmed PR (pancreatic, on treatment 20 wks), and 24 pts with stable disease (ranged from 6 to 47 wks). Preliminary assessment of PK data suggested no apparent drug-drug interactions with unaltered PK profiles of each drug when administered in combination. Conclusions: In combination the maximum tolerated doses of MK-2206 and selumetinib are 135 mg QW and 100 mg QD, respectively. This combination of investigational agents demonstrated preliminary antitumor activity in pts with advanced cancer. [Table: see text]

BackgroundAgonistic 4-1BB monoclonal antibodies were preclinically validated as promising cancer immunotherapies, both as monotherapy and as potentiators of the activity of PD-(L)1–blocking agents. However, toxicity and a narrow therapeutic window have hampered their clinical development. DuoBody-PD­-L1×4-1BB, a first-in-class, bispecific, next-generation checkpoint immunotherapy, was designed to overcome these limitations by activating T cells through conditional 4-1BB costimulation, while simultaneously blocking the PD-L1 axis. We present preliminary data from the ongoing, first-in-human, open-label, phase I/IIa trial of DuoBody-PD-L1×4-1BB in advanced solid tumors (NCT03917381).MethodsDuring dose escalation, patients with metastatic or unresectable solid tumors not eligible for standard therapy received flat-dose DuoBody-PD-L1×4-1BB (25–1200 mg) intravenously every 3 weeks until disease progression or unacceptable toxicity. Primary endpoints were dose-limiting toxicities (DLTs) and adverse events (AEs). Secondary endpoints included pharmacokinetic parameters and antitumor activity (RECIST 1.1). Pharmacodynamic biomarkers and antitumor activity (iRECIST) were assessed as exploratory endpoints.ResultsAs of June 22, 2020, 61 patients were enrolled (median age: 59 years). The most common cancer types were colorectal (19.7%), ovarian (14.8%), pancreatic (9.8%), and NSCLC (9.8%). Patients had previously received a median (range) of 3 (1–11) treatments; 44.2% had prior anti-PD-(L)1 immunotherapy. Patients received a median (range) of 4 (1–15) treatment cycles; Cmax was observed shortly after the end of infusion (mean T½: 2.3–10.3 days). Maximum tolerated dose was not reached; 6 patients experienced DLTs. The most common (=10%) treatment-related AEs (all grades; grades 3–4) were transaminase elevation (24.6%; 9.8%), hypothyroidism (16.4%; 1.6%), and fatigue (13.1%; 1.6%). Treatment-related grade-3 transaminase elevations decreased upon corticosteroid administration; no treatment-related bilirubin increases or grade-4 transaminase elevations occurred. Disease control, including stable disease at first assessment and partial responses in triple-negative breast cancer, ovarian cancer, and immune checkpoint inhibitor (ICI)–pretreated NSCLC, occurred in 40/61 patients (65.6%). Pharmacologic activity, as measured by modulation of adaptive immunity mediators, was observed across a broad range of dose levels. Peripheral proliferating (Ki67+) CD8+ effector memory T cells and serum interferon-gamma levels showed maximum induction relative to baseline (p=0.01) 8 days following treatment.ConclusionsDuoBody-PD-L1×4-1BB demonstrated biologic activity and a manageable safety profile. Encouraging early clinical activity across different dose levels was observed in a heavily pretreated population with advanced solid tumors, including those resistant to prior immunotherapy or typically less sensitive to ICIs. Expansion cohorts of patients for whom DuoBody-PD-L1×4-1BB treatment could be relevant and biologically sound have started enrollment.

13026 Background: ON-1910.Na is a new chemical entity, novel cell cycle inhibitor which arrests cells in G2/M, affects phosphorylation of several regulatory kinases and lacks cross resistance to other standard chemotherapy agents. This is a first-in-man Phase I dose escalation study to determine the dose limiting toxicities, recommended Phase II dose, and pharmacokinetic (PK) profile, and to document any antitumor activity of ON-01910.Na. Methods: Patients had histologically confirmed solid tumors refractory to standard therapy. ON-1910.Na, formulated as a solution in PEG400, was administered as a 2-hour infusion on days 1, 4, 8, 11, 15, and 18 followed by a 10 day observation period for a total of 28 days per cycle. The initial dose was 80 mg and was escalated using an accelerated titration schedule; one patient was treated per cohort until grade 2 toxicity was documented. A dose confirmation cohort of up to 12 patients will be treated at the maximun tolerated dose (MTD). A comprehensive PK study was performed on days 1 and 15 of the first cycle, plus trough samples were collected. Results: Thirteen patients (7F, 6M; ages 46–73) have received 20 cycles. Dose levels of 80, 160, 320, 480, 800, 1280, 2080, and 3120 mg were evaluated in 8 patients, and a further dose of 4370 mg has been evaluated in 5 patients. Toxicities have been anemia (2 G1, 1 G2), leucopenia (1 G1, 1 G2), hyperglycemia (2 G1), elevated AST/ALT (1 G1, 1 G2), nausea (3 G1), diarrhea (3 G1), skeletal pain (5 G1, 1 G2), abdominal pain (2 G1), tumor pain (1 G2), and fatigue (3 G1, 1 G2), and have clustered at the latter 3 dose levels. PK analysis shows increasing ON-1910.Na exposure with increasing doses. ON-1910.Na has a low clearance (13 L/h), long half-life (20 h), distribution in excess of blood volume (58 L) and PK parameters are similar on days 1 and 15. Approximately 3-fold and 5-fold inter-subject variation in ON-1910.Na clearance was observed on days 1 and 15, respectively. No antitumor activity has been documented by standard criteria. Conclusions: Dose escalation is continuing. [Table: see text]

Abstract Background: The presented phase I, first-in-human study evaluated the tolerance, pharmacokinetics, and preliminary efficacy of larotinib mesylate in patients with advanced solid tumors.Methods: Cancer patients were assigned to receive larotinib mesylate at 50–400 mg dose levels until disease progression or intolerance. Dose-limiting toxicities were assessed during Cycles 0 and 1. Pharmacokinetic evaluations were performed after the first dose and at steady-state. Results: Twenty-five patients with solid tumors were enrolled in the dose-escalation study. No DLTs were observed. Acne-like rash (68.0%), diarrhea (48.0%), paronychia (48.0%), and anemia (48.0%) were the most reported treatment-related adverse events. No clear linear pharmacokinetic characteristic could be drawn, and obvious accumulation was observed. Two patients with non-small cell lung cancer experienced a partial response, and 15 patients had stable disease after treatment. Conclusion: Continuous oral administration of larotinib mesylate at 50–400 mg daily demonstrated a favorable safety profile, and anti-tumor activity was observed in patients with advanced solid tumors.Trial registration: registration no.ChiCTR-OPC-15007153, registered 28 September 2015 at http://www.chictr.org.cn

3016 Background: BI 907828, a highly potent and orally administered MDM2-p53 antagonist, showed antitumor efficacy in vivo, especially in TP53 wild-type MDM2-amplified de-differentiated liposarcoma (DDLPS) patient-derived xenografts and syngeneic models. Methods: NCT03449381 is a phase I study of BI 907828 in pts with solid tumors. The objectives of the dose-escalation part were to determine the maximum tolerated dose (MTD) based on the frequency of pts with dose-limiting toxicities (DLTs) during cycle 1, determine the recommended dose for expansion, and evaluate the safety and tolerability of two dosing schedules: BI 907828 given on day 1 of 21-day cycles (Arm A) or days 1 and 8 of 28-day cycles (Arm B). Dose escalation was guided by a Bayesian logistic regression model. The secondary objectives include pharmacokinetics (PK), pharmacodynamics and antitumor activity. Results: At January 15, 2021, 54 pts with advanced solid tumors (median of 2 lines of prior systemic therapies; range 0–11) were treated with BI 907828 (Arm A, 29 pts, dose range 10–80 mg; Arm B, 25 pts, dose range 5–60 mg). In Arm A, 5 pts experienced DLTs in cycle 1, including one Grade (Gr) 3 Nausea and one Gr 3 Thrombocytopenia at 45 mg, one Gr 3 Enterocolitis at 60 mg, and one Gr 4 Neutropenia and one Gr 4 Thrombocytopenia at 80 mg. In Arm B, 3 DLTs were reported: one Gr 4 Thrombocytopenia at 45 mg, one Gr 4 Neutropenia associated with Gr 4 Thrombocytopenia, and one Gr 3 Neutropenia at 60 mg. The most common Gr 3/4 treatment-related adverse events (AEs) were Thrombocytopenia (28.6%), Neutropenia (10.7%) and Nausea (10.7%) in Arm A, and Thrombocytopenia (16.6%) and Neutropenia (12.5%) in Arm B. Preliminary PK data indicate that BI 907828 reaches Tmax at 4–6 h. Mean plasma exposures (Cmax and AUC0-inf) increased with dose. The geometric mean (gMean) Clearance/F was 5–19 mL/min and the gMean apparent volume of distribution was 23–57 L. The gMean half-lives estimated after the 1st dose were 26–55 h. Inter-patient variability in exposure was moderate. An increase in the target engagement biomarker GDF-15 in plasma was observed. The mean fold-change from baseline ranged from 8 to 49. Antitumor activity was seen in both schedules. In Arm A, a confirmed PR was seen in 2 pts with MDM2-amplified LPS (one PR lasted > 2 years) and SD in 17 pts. In Arm B, 2 pts had PR (one confirmed in MDM2-amplified LPS and one not yet confirmed in MDM2-amplified pancreatic adenocarcinoma) and 14 had SD. Of note, 5 of 10 pts with DDLPS were progression-free for ≥9 months. Conclusions: BI 907828 showed a manageable safety profile, favorable PK properties and early signs of efficacy, especially in MDM2-amplified tumors. With both dosing regimens, DLTs were Neutropenia and Thrombocytopenia. Non-hematologic AEs, mainly gastrointestinal, were mostly low-grade and not dose-limiting. The MTD of 60 mg in Arm A (day 1 of 21-day cycles) and 45 mg in Arm B (days 1 and 8 of 28-day cycles) are awaiting confirmation. Clinical trial information: NCT03449381.

BackgroundCitarinostat (CC-96241; previously ACY-241), an oral inhibitor of histone deacetylases (HDACs) with selectivity for HDAC6, has demonstrated synergistic anticancer activity with paclitaxel in multiple solid tumor models. Combination therapy using citarinostat with paclitaxel was evaluated in this phase Ib 3 + 3 dose-escalation study in patients with advanced solid tumors.MethodsPatients with previously treated advanced solid tumors received citarinostat 180, 360, or 480 mg once daily on days 1 to 21 plus paclitaxel 80 mg/m2 on days 1, 8, and 15 of 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was determination of the maximum tolerated dose (MTD). Secondary endpoints included safety, antitumor activity, pharmacokinetics, and pharmacodynamics.ResultsTwenty patients were enrolled and received study treatment; 15 had received prior taxane therapy. No dose-limiting toxicities were reported at any dose; therefore, the MTD was not identified. Citarinostat 360 vs 480 mg was associated with reduced incidence and severity of neutropenia. Three patients experienced a confirmed partial response and 13 achieved stable disease. Pharmacokinetic parameters were linear up to citarinostat 360 mg, the dose at which the highest levels of histone and tubulin acetylation were observed in peripheral blood mononuclear cells.ConclusionsThe combination of citarinostat plus paclitaxel showed an acceptable safety profile, with no unexpected or dose-limiting toxicities and potential evidence of antitumor activity in patients with heavily pretreated advanced solid tumors. Citarinostat 360 mg once daily is considered the recommended phase II dose for use in combination with paclitaxel 80 mg/m2 every 3 of 4 weeks. This trial is registered on ClinicalTrials.gov (NCT02551185).

TPS2619 Background: The vascular endothelial growth factor C (VEGFEC) induces angiogenesis via activation of both VEGFRE2 and VEGFRE3, as well as lymphangiogenesis via activation of VEGFRE3. VGX-100 is a novel fully human IgG1λ neutralizing monoclonal antibody directed against human VEGFEC. Synergism between the VEGF-A inhibitor, bevacizumab and VGX-100 has been documented pre-clinically. It is thought that tumoral escape and relapse following VEGF-A inhibition, may in part be due to increased VEGF-C that signals through VEGFR-2 and VEGFR-3. Therefore the premise of this study is that administration of VGX-100 in conjunction with bevacizumab would block the two key ligands for VEGFRE2 along with blocking VEGFR-3-mediated tumor angiogenesis and lymphangiogenesis, and thus this drug combination will be clinically synergistic. This study (NCT01514123) is enrolling at MD Anderson and UCLA. Methods: Objectives:establish the safety and toxicity, MTD, pharmacokinetic and pharmacodynamic / biomarker profiles, as well as preliminary anti-tumor activity in refractory pts. Eligibility: pts with advanced solid tumors, good organ function, ECOG PS 0-1, any number of prior therapies, no CNS or cerebrovascular haemorrhage, no MI or reversible posterior leukoencephalopathy syndrome associated with prior anti-VEGF/anti-VEGFR therapy. Design: This is an open-label phase I dose escalation study with a standard “3+3” design. The study has two arms: safety data from the 28 day DLT period from Arm A (VGXE100 monotherapy at 6 cohort dose levels: 1, 2.5, 5, 10, 20 and 30 mg/kg, QW) will be available prior to starting the equivalent dose level in Arm B (VGXE100 at 5 cohort dose levels: 2.5, 5, 10, 20 and 30 mg/kg QW with bevacizumab at doses of either 5 or 10 mg/kg, Q2W). Accrual has completed in Cohorts A1 to A5 and B1 to B2. Accrual is underway for Cohort A6 and B3. Clinical trial information: NCT01514123.
