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.

TPS3169 Background: DNA-dependent protein kinase (DNA-PK) regulates a key DNA damage response (DDR) pathway for double-strand break (DSB) repair. DNA-PK inhibition augments DNA DSB damage generated by many antitumor therapies, including RT. DNA damage and repair impact the interaction of tumors with the immune system; combining immune checkpoint inhibitors (CPIs) with RT + DDR-targeted agents may modulate the tumor immune microenvironment, enhancing responsiveness to CPIs. M3814 (small molecule selective DNA-PK inhibitor) has demonstrated monotherapy activity in several tumor cell lines, and M3814 + RT combined with avelumab (programmed death ligand 1 mAb) significantly delayed tumor growth vs either agent alone + RT in MC38 syngrafts. This study will evaluate the clinical utility of M3814 combined with avelumab ± RT in pts with advanced solid tumors. Methods: NCT03724890 is a 2-part first-in-man study in adult pts with advanced or metastatic solid tumors. Part A is enrolling pts with measurable/evaluable solid tumors (RECIST v1.1); Part B will enrol pts with primary or metastatic tumor(s) in the lung which is/are amenable to be irradiated. In Part A, M3814 will be given orally twice daily. In Part B, M3814 + TRT will be given once daily, 5 days/wk for 2 wk. In both parts, pts will receive avelumab iv once every 2 wk from Day 1 until disease progression/unacceptable toxicity. Part B will initiate once the Safety Monitoring Committee declares the first dose level of Part A to have acceptable safety/tolerability. Primary objectives are to define the recommended Phase 2 dose (RP2D) of M3814 when combined with avelumab (Part A) and with avelumab + TRT (Part B) via dose-limiting toxicities (DLTs) occurring during the first 3/4 (Part A/B) wk of treatment. Secondary objectives include safety/tolerability, pharmacokinetics, immunogenicity, preliminary antitumor activity (BOR, PFS, OS). Sample size for each part depends on the number of DLTs/dose levels for M3814; dose escalation will be based on a Bayesian logistic regression model with overdose control. Part A aims to include 6–24 pts (≤4 dose levels), Part B 6–18 pts (≤3 dose levels). Recruitment began in Dec 2018. Clinical trial information: NCT03724890.

3586 Background: TP-3654 is an oral, second generation, potent PIM-1 kinase inhibitor with activity against PIM 2, 3 and favorable selectivity against other kinases. These cytoplasmic serine/threonine kinases are highly expressed in many cancers and their oncogenic potential has been largely attributed to supressing apoptosis downstream of stimuli including inflammatory cytokines and other immune effectors. TP-3654 has efficacy in various hematologic and solid tumor models inducing stromal Pim-1 also has been shown to mediate various aspects of the tumor microenvironment. Thus, Pim kinases are attractive targets for the treatment of many human malignanices. Methods: A first in human, multicenter, phase 1, dose escalation study using a standard 3+3 design with a modified Fibonacci scheme to examine the safety and clinical activity of TP-3654 in patients with advanced solid tumors. Results: Ten patients were enrolled between 30Apr and 31Dec2019 receiving 480, 720, and 1080 mg respectively. Grade 3 AEs were scrotum wound infection, altered mental status, anemia, fall, and lower extremity edema, none were related to study drug and all were manageable with supportive care. There were no Grade 4 or 5 AEs and no DLTs. Median duration of SD was 5.5 months (6/10) and with prolonged SD > 16wks (4/10). One CRC patient with 4 lines of prior therapy had a 22% reduction in tumor volume (SD > 5+ mos). TP-3654 plasma PK values (Cmax, AUC) continuously increased through all 3 cohorts. Average Cmax (ng/mL) and AUC0-24 (ng*hours/mL) were 195, 1965 (480mg); 357, 3310 (720mg); 735, 6922 (1080mg), respectively. PK values increased linearly with higher doses without reaching saturation. Peripheral Blood Mononuclear Cells were isolated from subjects prior and up to 24hours after treatment. Western Blot from protein lysates revealed a decrease in phosphorylation of BAD and p70s6K proteins, both regulated by PIM-1 kinase. Conclusions: These findings suggest that TP-3654 is tolerated as a monotherapy in patients with heavily pretreated, relapsed, and resistant solid tumors warranting further clinical development in selected indications.

3611 Background: TP-1287 is a an orally bioavailable phosphate prodrug of alvocidib, a cyclin dependent kinase 9 (CDK9) inhibitor. TP-1287 exhibits potent inhibition of intracellular kinases including CDK9. Inhibition of CDK9 leads to downregulation of the BCL-2 family member, MCL-1, which in turn inhibits tumor growth in preclinical animal models of prostate, breast, and lung carcinomas. Methods: This is a multicenter, Phase 1, dose escalation study using a standard 3+3 design with a modified Fibonacci scheme to examine the safety and clinical activity of TP-1287 in patients with advanced solid tumors. Patients will be added at the maximum tolerated dose (i.e. expansion cohort) to test TP-1287 as a single agent in patients with castrate resistant prostate cancer. Results: Twenty-two patients who were enrolled between December 2018 and January 2020 received a range of doses from 1 mg QD to 11 mg BID over 7 cohorts. Data are available for 20 patients as of the data cutoff date. TP-1287 plasma PK Cmax and AUC increased in near linear fashion over cohorts 1 thru 6, reaching 80 ng/mL and 499.3 ng*h/mL in cohort 6 for Cmax and AUC, respectively. TP-1287 treatment resulted in dose-dependent reductions of phospho-RNA Pol II, consistent with CDK9 inhibition, as measured by a flow cytometric assay assessing pharmacodynamic changes in phosphorylation state in PBMCs. The most frequently observed Grade 3 AE was unrelated anemia in 2 patients. All other events of Grade 3 (9 events/7 patients) and Grade 4 (1 event/seizure with new CNS mets) were unlikely related or unrelated. Clinical benefit was seen in one sarcoma patient with PR (15+cycles), one RCC patient with SD (7+cycles) and 2 bladder cancer patients with SD (6 and 8 cycles). Conclusions: These findings suggest that TP-1287 is tolerated as a monotherapy in patients with heavily pretreated, relapsed, refractory solid tumors and further clinical development in selected indications is warranted. Clinical trial information: NCT03298984 .
