Study Objective

2583 Background: Anti-programmed death 1 (PD-1) therapy has improved clinical outcomes for patients (pts) with advanced solid tumors but unmet needs remain. T-cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibition motif domains (TIGIT) is a co-inhibitory, immune checkpoint receptor. Ociperlimab (OCI; BGB-A1217) is a novel, humanized, monoclonal antibody that binds to TIGIT with high affinity and specificity. OCI has demonstrated competent binding with C1q and all Fcγ receptors and induces antibody-dependent cellular cytotoxicity. Preclinical studies demonstrated dual targeting with OCI and tislelizumab (TIS), an anti-PD-1 antibody, produces synergistic immune cell activation and enhanced antitumor activity. Methods: AdvanTIG-105 is a phase 1, open label, multicenter, dose-escalation study (NCT04047862) that assessed the safety and preliminary antitumor activity of OCI plus TIS in pts with advanced, metastatic, unresectable solid tumors, for which standard therapy was ineffective or unavailable. Eligible pts had an Eastern Cooperative Oncology Group performance score ≤1 and no prior therapy targeting TIGIT. Pts received OCI intravenously (IV) on Day 1 of Cycle 1 and TIS 200 mg IV on Day 8. Pts were monitored for dose-limiting toxicities (DLTs) until Day 28. If tolerated, OCI and TIS were administered sequentially on Day 29 and every 3 weeks (Q3W) thereafter. Pts received escalating doses of OCI (50-900 mg) plus TIS 200 mg. The study objective was determination of recommended phase 2 dose (RP2D) of OCI plus TIS. Study endpoints included assessment of adverse events (AEs), pharmacokinetics and antitumor activity. Data cut-off was October 12 2020. Results: 24 pts with various advanced solid tumors received OCI plus TIS. At baseline, pts had undergone a median of 2 prior treatment regimens; 9/24 (37.5%) pts had received prior immunotherapy. Median follow-up time was 17 weeks. No DLTs were observed. 20 pts had ≥1 treatment emergent AE (TEAE) and most TEAEs were grade ≤2; fatigue (6 pts) and diarrhea (4 pts) were most commonly reported. No pts had grade ≥4 TEAEs or TEAEs leading to death. There were 2 grade 3 immune related AEs (colitis and low cortisol). One pt on OCI 450 mg achieved partial response and 9 pts had stable disease. The longest duration of stable disease was 36 weeks (1 pt on OCI 150 mg). After administration, serum concentration of OCI decreased in a biphasic manner. Exposure to OCI increased proportionally with dose, and TIGIT receptor occupancy was sustained at ≥50 mg doses. Conclusions: OCI in combination with TIS was well tolerated across all doses in pts with advanced solid tumors. The RP2D was OCI 900 mg plus TIS 200 mg Q3W. Clinical trial information: NCT04047862.

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.

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.
