2534 Background: Preclinical data suggest that combined Ang1/2 and mTOR blockade has synergistic anti-cancer activity. The combination of Tr (inhibits angiogenesis by preventing interaction of Ang1/2 with Tie2) with the mTOR inhibitor T was evaluated in pts with advanced solid tumors to determine safety, tolerability, maximum tolerated dose (MTD), pharmacodynamics and preliminary antitumor activity. Methods: Pts were enrolled using 3+3 design. Tr and T were dosed on Day 1 (D1), 8, 15 and 22 of a 28-day cycle. Peripheral blood was collected for evaluation of Tie2-expressing monocytes (TEMs) and thymidine phosphorylase (TP) (an angiogenic enzyme increased in TEMs upon Tie2 stimulation) by flow cytometry. Tumor response was assessed every 2 cycles. Results: 13 pts have been enrolled, 6 at dose level (DL) 1 (15mg/kg Tr + 25mg T) and 7 (1 died from disease before DLT assessment) at DL -1 (15mg/kg Tr + 20mg T). Median age was 57yrs, ECOG 0-1, median previous chemotherapy lines 3 (range 1-8). In DL 1, 1/6 pts experienced DLT (Grade (Gr) 2 pneumonitis). In view of frequent Gr2 adverse events (AEs) in DL 1, DL -1 was evaluated with DLTs in 2/6 evaluable pts (Gr3 mucositis and intolerable Gr2 limb edema preventing start of cycle 2 within 14 days). The most common related AEs (all Gr across both DL) were: fatigue (77%), edema (69%), anorexia (62%), and nausea (54%). Common Gr≥3 AEs included lymphopenia (23%) and fatigue (23%). Of 10 evaluable pts, best RECIST responses were: 1 breast cancer pt (ER+/ HER2-/ PIK3CA mutant) with PR (now in cycle 9), 7 pts with SD, and 2 pts with PD. Four pts with ovarian cancer (1 PIK3CAmutant) had SD ≥11weeks with 2/3 pts (1 not evaluable) demonstrating GCIG response (>50% decrease in CA125). In preliminary analyses, TP expression in TEMs was decreased (mean -18%) in 4pts with tumor shrinkage, but increased (+6%) in 1pt with tumor growth, suggesting a trend between reduced TP and tumor response. Conclusions: The MTD was exceeded at 15mg/kg Tr and 20mg T weekly. The safety of 10mg/kg Tr and 20mg T weekly is currently being evaluated. The combination of Tr and T shows early signs of antitumor activity. TP expression in TEMs by flow cytometry as an early marker of treatment benefit warrants further evaluation. Clinical trial information: NCT01548482.

Pdx Models

Patient-derived xenograft (PDX) models are used as powerful tools for understanding cancer biology in PDX clinical trials and co-clinical trials. In this systematic review, we focus on PDX clinical trials or co-clinical trials for drug development in solid tumors and summarize the utility of PDX models in the development of anti-cancer drugs, as well as the challenges involved in this approach, following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Recently, the assessment of drug efficacy by PDX clinical and co-clinical trials has become an important method. PDX clinical trials can be used for the development of anti-cancer drugs before clinical trials, with their efficacy assessed by the modified response evaluation criteria in solid tumors (mRECIST). A few dozen cases of PDX models have completed enrollment, and the efficacy of the drugs is assessed by 1 × 1 × 1 or 3 × 1 × 1 approaches in the PDX clinical trials. Furthermore, co-clinical trials can be used for personalized care or precision medicine with the evaluation of a new drug or a novel combination. Several PDX models from patients in clinical trials have been used to assess the efficacy of individual drugs or drug combinations in co-clinical trials.

17051 Background: BORT(PS-341) is a small molecule proteasome inhibitor while PEM, a multi-targeted antifolate, inhibits multiple enzymes involved in purine/pyrimidine formation. Both are approved anti-cancer agents. We examined the safety and tolerability of two different schedules of BORT and PEM in patients with advanced solid tumors. Methods: Two dose escalation trials (Arm A and Arm B) were conducted simultaneously. PEM was given every 21 days in both arms (500–600 mg/m2 IV). Arm A: BORT was given D1,4,8 &11 (0.7–1.3 mg/m2). Arm B: BORT was given D1 & 8 (1.0–1.6 mg/m2). All patients received vitamin B12, folic acid and decadron. Dose limiting toxicity (DLT) was defined as: grade (GR) 4 platelets (plts) (≤25K); GR 3 plts (25K-49,999K) with bleeding, requirement for transfusion, or lasting > 7 days; febrile neutropenia; GR3 ANC (ANC ≤1.0 × 109) with documented infection, or any ≥ GR3 non-heme toxicity. Results: 18 patients have been treated on 3 of the 4 planned dose levels. Tumor types included lung (12), prostate (2), breast (1), thymus (1), head & neck (1) and adenoid cystic carcinoma (1). Pt. characteristics: Median age 65 years; Sex M/F = 7/11; Performance Status ≤1/2 = 18/0. There have been no DLTs in either arm (Dose level 3-Arm A: PEM 500 mg/m2, BORT 1.3 mg/m2; Arm B:PEM 500 mg/m2, BORT 1.6 mg/m2). Most common GR3/4 toxicities were: neutropenia 27% and lymphopenia 11%. Of 17 evaluable patients: 1 had partial response, 11 had stable disease, 5 had progressive disease. Mean number of cycles: 4. Arm A had more doses held during the first cycle than Arm B (6 doses held vs. 1 dose held). Accrual to the final dose level in both arms is ongoing. Conclusions: 1) PEM in combination with BORT is feasible and tolerable. 2) Thus far, there are no differences in toxicity between the arms. 3) A randomized, multi-institutional phase II study will examine the efficacy of these two schedules in patients with NSCLC.

3574 Background: Belinostat (PXD101), a HDAC inhibitor of the hydroxamate class has shown anti-tumor preclinical activity in combination with other standard chemotherapeutic agents. In Ph. I and II clinical trials the MTD for belinostat has been established at 1,000 mg/m2/d. This Ph I/II study assesses safety, and anti-cancer activity of belinostat administered in combination with C and/or P. Methods: Sequential cohorts of 3–6 patients (pts) with advanced solid tumors and PS 0–2 were recruited to determine the MTD of standard dose C and/or P with escalating doses of belinostat administered as a 30-min IV infusion daily for 5 days (d) every 21 d. C and/or P were administered 2–3 hours following infusion of belinostat on d 3. Results: 23 pts have been treated with a mean of 5 cycles (range 1 - 15) at 5 dose levels: C and belinostat (600 mg/m2) (5 pts); P and belinostat (600 mg/m2) (5 pts); C and P and belinostat (600 mg/m2) (3 pts); C and P and belinostat (800 mg/m2) (4 pts); C and P and belinostat (1,000 mg/m2) (6 pts). Possibly drug-related grade 3 or 4 toxicities were thrombocytopenia (2), vomiting (1), sensory neuropathy (1), myalgia (1), and fatigue (1).No DLT was observed. One SAE (grade 1 T-wave morphology change) was graded as possibly drug-related. No QTcf greater than 500ms were reported. There are 2 confirmed PRs: 1 with heavily treated metastatic rectal cancer and 1 with gemcitabine pre-treated metastatic pancreatic cancer. An additional 11[E1] patients had SD for 2–15 cycles, with 4 being SD for >10 cycles. One pt with mixed mullerian cancer of ovarian origin with SD had an 81% reduction in CA-125 to normal levels after 6 cycles. [E1]If you include MMMT pt as SD on radio. Conclusions: Belinostat with standard dose C and/or P is well-tolerated and shows clinical activity in heavily pre-treated patients with advanced metastatic disease. Recruitment to a phase II expansion in pts with recurrent ovarian cancer is ongoing. No significant financial relationships to disclose.

2577 Background: YH001 is a humanized anti -hCTLA-4 IgG1 mAb that relieves CTLA-4-mediated immunosuppression, and thereby enhances the T-cell-mediated antitumor immune response. Pre-clinical data have shown potent anti-cancer activity when combined with anti-PD-1 mAb. Methods: This is an ongoing phase 1 dose-escalation study. Patients (pts) with advanced solid tumors received YH001 by IV administration at 0.05 to 6.0 mg/kg for 1 cycle (21 days) then in combination with Toripalimab (anti-PD-1 mAb) at 240 mg Q3W for 4 cycles. An accelerated titration method followed by the standard “3+3” design was utilized to evaluate safety, tolerability and preliminary efficacy. Results: As of 31-Dec-2020 data cut-off, 10 pts were enrolled and treated at 0.05 mg/kg (n = 2), 0.1 mg/kg (n = 3), 0.3 mg/kg (n = 3) and 1 mg/kg (n = 2). The median age was 62 years (range 46-74). Baseline ECOG scores were 0 (n = 8), 1(n = 2) with all pts progressed after a median of 2 prior lines of available standard therapy (range 1-4) including 1 pt progressed after immunotherapy of pembrolizumab. There were no dose limiting toxicities (DLT) observed. No severe adverse events (SAEs), Grade (G) 3 or above adverse events (AEs) and AEs leading to treatment discontinuation were reported. Twelve drug related AEs were all G1/2 events including 2 G2 AEs (1 rash maculopapular at 0.05mg/kg, 1 hypothyroidism at 0.1mg/kg), 10 G1 AEs (1 hypotension, 1 dry skin, 1 pruritus at 0.05mg/kg; 1 rash, 1 rash macular, 1 hyperthyroidism, 2 rash pruritus at 0.1mg/kg, 2 fatigues at 0.3mg/kg). Among 7 patients having imaging tumor assessment by RECIST v1.1, there were 4 SD, including 1 at 0.05 mg/kg with tongue carcinoma at week 8 assessment, 1 at 0.1 mg/kg with nasopharyngeal carcinoma at week 8 and 15 assessment, 2 at 0.3 mg/kg with gastroesophageal junction cancer and uterus leiomyosarcoma at week 8. Conclusions: YH001 combined with Toripalimab is safe and tolerable up to 1 mg/kg dose level. Updated safety and preliminary efficacy data will be presented. Clinical trial information: NCT04481009.
