TPS3168 Background: Multi-target kinase inhibitors have gained increasing attention in the past few years due to their capabilities of simultaneously targeting several hallmarks of cancer. Triple negative breast cancer (TNBC), the most aggressive type of breast cancer, is a highly heterogeneous disease composed of several subtypes with distinct genomic profiles and activating pathways. TT-00420 is a multi-target kinase inhibitor that targets Aurora A/B, receptor tyrosine kinases (RTKs) involved in angiogenesis, and other kinases involved in tumor-associated inflammation and immune escape. Preclinical studies have established signs of efficacy for TT-00420 in TNBC. Targets inhibited by TT-00420 are among the key dysregulated pathways directly involved in the tumorigenesis of TNBC. TT-00420 is efficacious against most subtypes of TNBC cell lines. This anti-TNBC activity is confirmed in both cell line derived xenograft (CDX) and patient derived xenograft (PDX) TNBC model in vivo, in which TT-00420 is active both as first-line and second-line treatment. TT-00420 demonstrated good oral bioavailability and pharmacokinetic properties in mice, rats and dogs, and revealed mechanism-related but manageable toxicities. The IND approval of TT-00420 was granted by the FDA on Sept. 27, 2018. Methods: TT420X2101 is an open-label, first-in-human, multicenter, phase I study including a dose escalation portion in adult patients with advanced solid tumors, followed by dose expansion in two parallel cohorts, TNBC cohort (N=22) and selected advanced tumor (SAT) cohort (N=22). Adverse events will be evaluated per CTCAE v5.0 criteria, and tumor responses will be evaluated per RECIST v1.1 criteria. Patients aged 18-75 with measurable target lesion(s) at baseline and ECOG status of 0 or 1 will be enrolled. Patients are treated with a single daily oral administration of TT-00420 continuously for a 28-day cycle. Dose escalation is driven by Bayesian modeling with over-dose control. Approximately 66 patients are expected to be enrolled and treated in this study. Primary endpoint is to evaluate dose limiting toxicity (DLT) and identify maximum tolerate dose (MTD), if feasible, or establish recommended dose for Dose Expansion. Preliminary efficacy and PK profile will be evaluated as well. Enrollment is currently ongoing. Clinical trial information: NCT03654547.

3592 Background: Sunitinib malate (SU) is an oral, multitargeted tyrosine kinase inhibitor of VEGFRs, PDGFRs, KIT, RET, and FLT3, approved internationally for the treatment of advanced RCC and imatinib-resistant or -intolerant GIST. This phase I study assesses the safety, tolerability and pharmacokinetics (PK) of SU in combination with capecitabine (C). Methods: Pts with advanced solid tumors not amenable to curative therapy, previously treated with =2 prior chemotherapy regimens, and ECOG PS =1 were eligible. Prior antiangiogenic therapy was not permitted. Three SU schedules were evaluated: 4 wks on treatment followed by 2 wks off in 6-wk cycles (4/2 schedule); 2 wks on followed by 1 wk off in 3-wk cycles (2/1 schedule), and continuous dosing (CD schedule). In all cases C was administered orally bid on days 1–14. SU and C doses were alternately escalated in serial pt cohorts to determine the maximum tolerated dose (MTD) of SU for all schedules using a standard 3 + 3 design. PK and antitumor efficacy were also assessed. Results: A total of 50 pts have been enrolled; 28 pts have been treated on the 4/2 schedule: SU 50 mg + C 1,000 mg/m2, and SU 37.5 mg + C 1,250 mg/m2 were not tolerated. Dose limiting toxicities (DLTs) included: grade 3 myalgia (n=1), grade 3 fatigue (n=2), and grade 3 hand- foot syndrome (n=2). The MTD for the 4/2 schedule was SU 37.5 mg/day + C 1,000 mg/m2. No DLTs nor dose reductions were observed among 9 pts treated at the MTD. Preliminary PK data do not indicate drug-drug interactions between SU and C. 3 pts (1 each with breast cancer, neuroendocrine carcinoma, and thyroid carcinoma) achieved confirmed partial responses. On the 2/1 schedule patients are being accrued to SU 37.5 or 50 mg + C 1,000 mg/m2 and doses of SU 37.5 mg + C 1,000 mg/m2 or SU 25 mg + C 1,250 mg/m2 are being explored on the CD schedule. Conclusions: The combination of SU 37.5 mg/day (4/2 schedule) with C 1,000 mg/m2 in pts with advanced solid tumors appears tolerable. SU may be administered in combination with C with no apparent drug-drug interaction. Subsequent cohorts will define the MTD of SU administered on the 2/1 and CD schedules. Further studies of this combination in breast cancer are warranted. No significant financial relationships to disclose.

2578 Background: CZ48, the 20-O-propionate ester of camptothecin (CPT), is a prodrug of CPT first described by Cao et al. in 1998. The side-chain is enzymatically cleaved in tissues. This gives rise to CPT, a potent inhibitor of topoisomerase I. Methods: An open-label, single-arm, dose-escalation Phase I study was performed to determine the maximum tolerated dose (MTD) of CZ48 in patients with advanced solid tumors. Initial dosing started qd po 80mg/m2, advancing to 2560mg/m2 for 21 consecutive days, followed by 7 days rest. Dosing was restarted in cohorts of 3 patients tid po at 18mg/m2 and escalated to 1g/m2on a 5 days on, 2 days off schedule for 28 days. Patients were prescreened by measuring CPT levels in plasma following a single pilot dose of CZ48. Dose was doubled until occurrence of at least Grade 2 adverse event, at which time 3+3 patient cohorts with a dose escalation of 33%-100% were implemented. DLT in 2/6 patients defined the MTD as the preceding DLT dose. PK parameters were measured prior to dosing, days 1-5, and day 28 of Cycle 1. Results: Poor absorption led to initial qd dosing reaching 2560mg/m2 with no signs of DLT. Subsequent tid dosing showed improved plasma levels and arrival at DLT. 34 patients were treated across 8 dose levels from 18 to 1000 mg/m2. The most frequent study-related adverse effects were cystitis, vomiting, diarrhea and fatigue. Grade IV toxicities observed were febrile neutropenia, anemia, and thrombocytopenia. Preliminary PK data in the qd dosing showed poor correlation between dose and Cmax or AUC, while PK in tid patients showed slightly improved correlation between dose and both CZ48 AUC (Pearson's correlation coefficient ϱ=0.476, p<0.01) and CZ48 Cmax(ϱ =0.51, p<0.01). Evidence of clinical activity with stable disease ≥ 6 months was observed in 2 heavily pre-treated colon and one breast cancer patient. Conclusions: The MTD of tid po CZ48 administered 5 days on, 2 days off of 28-day cycle is between 750 mg/m2 and 576 mg/m2. Overall toxicity is relatively mild, with DLT being cystitis and myelosuppression. Even with tid dosing, PK values correlate poorly to dose. A new formulation with 3-5 fold higher preclinical absorption values is being considered for introduction into the trial. Clinical trial information: NCT00947739.

3076 Background: HM781-36B is a pan-HER tyrosine kinase inhibitor, which showed a potent activity against the gefitinib- or erlotinib-resistant, EGFR L858R/T790M double mutant cells. A phase I study was conducted to determine the MTD, pharmacokinetics, and antitumor activity. Methods: Eligible pts had advanced malignancies refractory to standard therapies. Standard 3+3 scheme was used in the dose escalation part, and additional 12 pts were enrolled in the expansion cohort of molecular enrichment. Results: In dose-escalation part, 43 pts (median age: 55 yrs (range 25-82), M:F=25:18, ECOG PS 0/1/2/3: 23/17/2/1, median prior chemotherapy: 4) were treated. DLTs were G3 diarrheas in 5 pts, one at 12 mg, 16 mg, 24 mg, and two at 32 mg. The MTD was determined as 24mg. The most common drug-related adverse events were diarrhea, stomatitis, rash, pruritus, and anorexia. Among 41 evaluable pts, 4 pts achieved PR (1 unconfirmed, duration of response: 11.9 mo, 7.07 mo+, 4.5 mo+), and 19 pts had SD. Two of 4 PR pts were Her2-positive breast cancer pts. The median duration of treatment in pts with PR or SD was 3.87 (2.47- 15.17) months. In the dose range of 0.5 to 24 mg, it showed linear pharmacokinetics proportional to dose-escalation, relatively short half-life, and little accumulation. Additional 12 pts in the expansion cohort are under treatment at 24 mg (6 pts: EGFR-mutant NSCLC, 3 pts: Her2-positive gastric cancer, 2 pts: Her2-positive breast cancer, 1 pt: rectal cancer). Conclusions: HM781-36B was safe and well tolerable in advanced solid tumors. Preliminary evidence of anticancer activity has been observed. Updated data will be presented at the meeting.
