2580 Background: YH003, a recombinant, humanized agonistic anti-CD40 IgG2 monoclonal antibody (mAb) specifically recognizes and agonizes CD40 on the antigen-presenting cells to enhance immune responses. Preclinical data have shown potent anti-cancer activity when combined with anti-PD-1 antibodies. Methods: This is an ongoing phase 1 dose-escalation study. Patients with advanced solid tumors receive YH003 by IV administration Q3W as monotherapy at 0.03 to 3.0 mg/kg for the first cycle (21 days) then in combination with Toripalimab at 240 mg Q3W for the 4 subsequent cycles in an accelerated “3+3” design. The safety, tolerability and preliminary efficacy data will be analyzed. Results: As of 31 Dec 2020 data cutoff, 9 patients (pts) were enrolled and treated at 0.03 mg/kg (n = 3), 0.1mg/kg (n = 3), and 0.3mg/kg (n = 3). The median age was 63 years (range 33-68). Baseline ECOG scores were 0 (7 pts) and 1 (2 pts) with a median of 2 prior lines therapy (range 1-7). 5 pts had received prior immunotherapy (PD-1/PD-L1 or PD-1+CTLA-4). As of data cutoff, no dose limiting toxicities (DLT) were observed. No Serious Adverse Event (SAE) or AEs leading to treatment discontinuation were reported. Four drug related AEs were reported including one Grade 1 (G1) choroidal thickening (related to YH003) at 0.03 mg/kg, one G1 fatigue (related to YH003) at 0.1 mg/kg, two G1 febrile episodes (one related to YH003 and the other related to combination treatment) at 0.3 mg/kg. Among 5 patients assessable for response, there were 2 SD (one with anti-PDL1 refractory Merkel cell carcinoma at 0.03 mg/kg and one with anti-PD1 refractory NSCLC at 0.1 mg/kg) and 1 PR with anti-PD1/anti-CTLA4 refractory ocular melanoma at 0.1 mg/kg. Conclusions: YH003 was well tolerated up to 0.3 mg/kg dose levels when combined with Toripalimab and has shown encouraging antitumor activity in patients with advanced solid tumors. Clinical trial information: NCT04481009.

TPS2673 Background: Immune checkpoint inhibitors directly targeting T cell activation have been successfully used in the treatment of various malignancies, nevertheless, the durable ORRs are low for certain indications. The low ORRs have been attributed to the immune suppressive tumor microenvironment (TME), composed of innate immune suppressive components such as tumor associated macrophages (TAM) and myeloid-derived suppression cells (MDSC). The potential contributions of innate immune modulation to anti-tumor immunity, suggest the need for the novel strategies to elicit a more efficient/robust immune response against the targeted malignant cells. Axl, Mer and CSF1R receptor tyrosine kinases play vital roles in promoting an immune suppressive TME by affecting TAM and MDSC populations and by decreasing antigen presentation on tumor cells. Q702 is a novel Axl/Mer/CSF1R inhibitor, able to modulate the TAM and MDSC population leading to CD8+ T cell activation and to increase antigen presentation of the tumor cells in syngeneic animal models. Q702, as a monotherapy, shows significant tumor growth inhibition in multiple syngeneic tumor models, and demonstrates synergistic effects with anti-PD-1 treatment particularly in high myeloid containing tumor models. Interestingly, intermittent administration of Q702 monotherapy demonstrates a more favorable immune cell population changes, possibly through preventing immune exhaustion secondary to negative feedback with continuous activation. These results suggest that Q702 monotherapy or in combination with existing therapies have a good potential to become a novel treatment strategy for patients with advanced solid tumors. Methods: “A Phase 1, Multicenter, Open-label, Dose-Escalation, Safety, Pharmacodynamic, Pharmacokinetic Study of Q702 with a Cohort Expansion at the RP2D in Patients with Advanced Solid Tumors. (NCT04648254)” is open and recruiting patients at 4 US investigative sites. Patients with histologically or cytologically confirmed advanced or metastatic solid tumors, that have progressed following SOC or for which there is no SOC which confers clinical benefit are being enrolled in this study. The study follows a standard dose escalation. The study will enroll up to 78 patients. The primary endpoint is to establish safety, PK profile and define the recommended phase 2 dose. The secondary and exploratory endpoints include establishing pharmacokinetic/pharmacodynamic relationship, potential biomarkers and preliminary anti-tumor activity. Clinical trial information: NCT04648254.

Anti Tumor Activity

2519 Background: Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is an EGF family member and a ligand for EGFR and Her4. U3-1565 is a fully human anti-HB-EGF monoclonal antibody with preclinical anti-tumor and anti-angiogenesis activity. In this study, we evaluated safety, tolerability, immunogenicity, pharmacokinetics (PK), pharmacodynamics (PD), and anti-tumor activity of U3-1565 in patients with advanced solid tumors refractory to standard treatment. Methods: The 3+3 method of enrollment and dose-escalation was used to test U3-1565 at 2, 8, 16, and 24 mg/kg once every two weeks (with the second dose given three weeks after the first), and at 24 mg/kg weekly. Results: 15 patients (11 females, 4 males; median age 62 (range 47-77) years; 5 CRC, 5 NSCLC, 3 ovarian and 2 other cancer) were enrolled, 3 in each dose level cohort. No dose-limiting toxicity was observed and a maximum tolerated dose was not reached. The highest administered dose of 24 mg/kg weekly generated Cmin above the predetermined target concentration corresponding to Cave resulting in 90% preclinical tumor growth inhibition. U3-1565 was safe and well tolerated with related AE consisting of infrequent and non-dose-related G2 (fatigue, anemia, and appetite loss, seen in 20, 13, and 7% of cases, respectively) and G1 toxicities. No anti-U3-1565 antibody was detected. U3-1565 showed bi-exponential disposition with Cmax and AUC increasing proportional to the dose across all dosing regimens. 13 patients discontinued the study, 12 due to progressive disease and 1 due to non-drug-related AE. After 6 months on study, 2 patients entered study extension phase: A 77 year-old female with NSCLC given 24 mg/kg every two weeks, showed SD (best SLD change -3%) for 26 weeks before progression; and a 76 year-old female with CRC given 24 mg/kg weekly, showed PR (best SLD change -35%) and remains on treatment after 71 weeks. Conclusions: U3-1565 is safe and well tolerated up to 24 mg/kg weekly. Anti-tumor activity was observed and is being further explored in an open-label, dose-expansion study. Clinical trial information: NCT0129041.

e15001 Background: Interim safety and PD data from an ongoing first-in-human, multi-center, open-label dose escalation study of XmAb20717 (XmAb20717-01; NCT03517488) are reported here. The primary objectives were to determine safety, tolerability, and the MTD and/or recommended doses (RDs). Secondary objectives included preliminary anti-tumor activity and PK/PD. Methods: A 3+3 dose escalation design was used to establish an MTD/RD(s) for infusions on Days 1 and 15 of each 28-day cycle. DLT evaluation was based on Cycle 1 through Day 28. Patients with selected solid tumors (in indications both with and without approved checkpoint therapy) who have exhausted standard of care are eligible. Results: As of 05FEB 2020, 34 patients were treated in cohorts 1-6 at fixed doses of 0.15 to 10 mg/kg. Patients had a median age of 57 years (range 32-81), a median time since initial diagnosis of 42 months (range 3 -313), and a median of 4 prior systemic therapies (range 0-9). 68% of patients had a TNM stage of III/IV, and 68% had been exposed to checkpoint therapy. XmAb20717 treatment was generally well tolerated through the highest dose cohort tested. Overall rates of Gr3/4 immune-related AEs occurred in 8 (24%) patients including elevations of transaminases 3 (9%), rash 2 (6%), lipase and amylase 1 (3%, without clinical symptoms or radiographic evidence of pancreatitis), lipase (alone) 1 (3%), pruritus 1 (3%), hyperglycaemia 1 (3%), arthritis 1 (3%) and colitis 1 (3%), all reversible. Responses were evaluated based on RECIST 1.1 criteria, and there was 1 CR reported (melanoma, progressed on prior pembrolizumab) at 10 mg/kg (highest dose level). Dose-dependent pharmacodynamic activity consistent with dual PD-1/CTLA-4 blockade was noted, namely a proliferative burst of both CD8 and CD4 T cells and induction of IFN-inducible chemokines (Table). Conclusions: XmAb20717 is generally safe and has demonstrated PD activity in heavily pretreated patients with selected advanced solid tumors. Dose escalation continues. Clinical trial information: NCT03517488 . [Table: see text]
