TPS465 Background: Tumor-associated macrophages (TAMs) support tumor growth and cause tumor resistance to chemotherapy and radiation therapy; myeloid-derived suppressor cells (MDSCs) suppress anti-tumor immunity and cause resistance to PD-1 inhibition. TAMs and MDSCs are both regulated by colony stimulating factor 1 (CSF1). Pexidartinib is a small molecule inhibitor of CSF1 receptor, CSF1R. The normal function of PD-1, expressed on the cell surface of activated T-cells, is to suppress excessive immune responses, eg, autoimmune reactions. Tumors utilize PD-1 signaling to downregulate immune-mediated elimination. Pembrolizumab is a potent, highly selective humanized monoclonal antibody that blocks interactions between PD-1 and its ligands, PD-L1 and PD-L2. We present the study design for a Phase 1/2a clinical trial assessing safety, efficacy, pharmacokinetics, and pharmacodynamics of the combination of pexidartinib and pembrolizumab in advanced solid tumors (NCT02452424). Methods: In Part 1 of this open-label, uncontrolled trial, patients with advanced solid tumors will receive pembrolizumab (200 mg IV q 3 weeks) and escalating daily oral doses of pexidartinib to establish the safety and tolerability of the combination and a recommended phase 2 dose (RP2D). In Part 2, the combination RP2D will be studied in an expanded panel of solid tumor cohorts in up to 475 patients, to assess safety and preliminary efficacy. The panel will include GI malignancies for which preclinical data support this combination, including gastric and gastro-esophageal adenocarcinoma, pancreatic cancer, cholangiocarcinoma, and GI stromal tumors. Overall response rate (RECISTv1.1) and progression free survival will be evaluated. Exploratory endpoints include novel biomarkers of clinical activity and drug mechanisms of action. A truncated sequential probability ratio test will be employed in each tumor cohort to allow early decision-making for futility or success. The results will support further development of the pexidartinib/pembrolizumab combination in the solid tumors that respond to treatment in this study. Clinical trial information: NCT02452424.

Trial in progress: A phase 1-2 multicenter, open-label, dose-escalation and dose-expansion study to evaluate the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of ABN401 in patients with advanced solid tumors.

TPS3157 Background: c-MET (hepatocyte growth factor (HGF) receptor) overexpression, either by gene amplification, or mutation is associated with oncogenic transformation in numerous malignancies including lung, gastric, skin, renal, colorectal, and pancreatic cancers. ABN401 inhibits the activation of c-MET by reversibly interfering with the binding of c-Met tyrosine kinase to adenosine triphosphate (ATP) and blocking the receptor's downstream signaling that has demonstrated efficacy in NSCLC and gastric cancer in mouse xenograft and PDx models. This clinical trial is in progress in patients with advanced cancers. Methods: ABN401 is being evaluated in an open-label, non-randomized, dose-escalation (phase 1) study in patients with advanced solid tumors, and dose-expansion (phase 2) in patients with targeted indications and c-MET biomarker expression (NCT04052971). The phase 1 explores ascending daily doses of oral ABN401 monotherapy in 21-day cycles to identify the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D). A preplanned extension (pilot expansion) study has been initiated based on predefined positive efficacy signals at intermediate doses up to 10 NSCLC patients who have c-MET alteration. Once RP2D is determined, the phase 2 expansion of up to 10-29 patients in four specific tumor-type cohorts is planned, utilizing a Simon's optimal two-stage design to evaluate the clinical activity of ABN401. ABN401-001 study began enrolling patients in August 2019 and is ongoing in Korean and Australia. Dose escalation up to cohort 4 has been completed, enrollment to cohort 5 began in November 2020. AEs are assessed according to CTCAE v5. Tumor response is determined according to RECIST 1.1 criteria and safety findings reviewed by the DRC, which will determine the RP2D and MTD. Key Phase 1 eligibility criteria include 1) histological or cytological diagnosis of melanoma or any type of carcinoma or sarcoma and 2) refractory metastatic disease, or refractory locally advanced disease not amenable to local therapy. For the extension (pilot expansion) study, patients must have NSCLC with MET exon 14 skipping, MET amplification and/or c-MET overexpression. An exploratory study is being conducted for co-development of a companion diagnostic (CDx) system including a CTC device and ddPCR kit through liquid biopsy. Clinical trial information: NCT04052971.

TPS2681 Background: Anti-PD-(L)1 immunotherapy improves outcomes for patients across various cancers; however, many patients do not benefit. Previous studies combining multi-site SBRT with anti-PD1 have confirmed feasibility and revealed induction of interferon signaling by SBRT. Elevated levels of serum IL8 (sIL8) associate with lack of response to anti-PD1 and we have observed that elevated IL8 is strongly associated with lack of response to immunotherapy and SBRT combinations. Overcoming IL8 induced epithelial-mesenchymal transitioning and trafficking of myeloid derived suppressor cells in tumor microenvironment therefore represents a promising strategy to overcome resistance. BMS-986253 is a fully human neutralizing antibody that binds to sIL8. The combination of BMS-986253 and nivolumab was safe in patients with advanced solid tumors. The present study aims to evaluate safety and preliminary efficacy of combining BMS-986253 with nivolumab and SBRT in patients with advanced solid tumors, Melanoma (MEL) and Renal Cell Carcinoma (RCC). Methods: This is a phase 1 open label single arm study (CT.gov: NCT04572451) which will include safety and efficacy cohorts. Patients will receive SBRT in 1-4 tumor lesions, in 3 or 5 fractions, at the total of 30 or 45 or 50 Gy based on the irradiated organ site. This will be followed by intravenous (IV) nivolumab (480mg q4 weeks (W)) and IV BMS-986253 (2400mg q2W) within seven days of completing SBRT. In the initial safety portion of the clinical trial, we will include 30 patients with advanced/metastatic solid tumors in order to evaluate safety. The primary endpoint of dose limiting toxicity will be assessed by continual Bayesian monitoring. The toxicities will be attributed to combination of SBRT/Immunotherapy as opposed to individual components. The secondary objective of the study is efficacy with an endpoint of objective response rate (ORR) as assessed by RECIST v1.1 in Mel and RCC. We will include 20 patients with MEL and RCC and compare against a historical benchmark of 20% ORR as sufficient signal of activity for further study. ORR will be assessed for association with serum IL-8 levels and radiation-induced changes in peripheral blood T cell populations. Clinical trial information: NCT04572451.

2568 Background: IL-2 and IL-15 signal through the shared IL-2/15 βγ receptor, but unlike IL-2, IL-15 does not expand regulatory T cells (Tregs), does not mediate activation-induced cell death and may have an improved therapeutic index. KD033 is a fusion antibody combining a fully human, high affinity anti-human Programmed Death Ligand 1 (PD-L1) IgG1 antibody with the human IL-15 receptor alpha (IL15Rα) sushi domain and human IL-15 (IL-15). KD033 (or its mouse cross reactive surrogate molecule, srKD033) has been extensively characterized in multiple in vitro and in vivo nonclinical studies. The fusion of anti-PD-L1 antibody to IL-15 significantly increases the maximal-tolerated dose (MTD) of srKD033 in mice compared to free IL-15. In addition, srKD033 has exhibited increased efficacy in rejecting tumors in mice as compared to the combination of its individual components, anti-PD-L1 antibody and IL-15. Methods: This is a phase 1, open-label, multiple ascending dose, multi-center clinical trial being conducted in patients with metastatic or locally advanced solid tumors (NCT04242147). The primary objective is to determine the safety and tolerability and the MTD of KD033. Secondary objectives include characterization of PK and immunogenicity, evaluation of CD8 T and NK cell activation and assessment of best overall response and duration of response. KD033 is administered by IV infusion over 30 minutes every 14 days. Accelerated intra-patient dose escalation across the initial three dose levels, followed by 3+3 escalation thereafter, is investigating dose ranges from 3 µg/kg to 600 µg/kg. Efficacy evaluation is planned in an expansion cohort of patients with PD-1/L1 refractory tumors. Results: A total of 7 patients have received treatment. Three patients were dosed in Cohort 1 and four patients were dosed in Cohort 2. Through two dose escalation cohorts (3 µg/kg – 25 µg/kg), no dose-limiting toxicities have been reported. Grade 1-2 treatment-related toxicities, when observed, resolved within 24 hours with supportive management. 6 patients are evaluable for treatment response with one patient (adenoid cystic carcinoma) in the first cohort having stable disease for more than 6 months. Conclusions: KD033 has been well tolerated early in dose escalation with on-mechanism pharmacodynamics consistent with IL-15 agonism. Clinical trial information: NCT04242147.

3003 Background: We report safety and tolerability of MEDI0562, a humanized IgG1κ OX40 monoclonal antibody (mAb), in combination with durvalumab (durva; anti-PD-L1 mAb) or tremelimumab (treme; anti-CTLA-4 mAb) in patients (pts) with previously treated advanced solid tumors. Methods: In this phase 1, open-label study (NCT02705482), adult pts received escalating doses of MEDI0562 (2.25, 7.5 or 22.5 mg/kg) every 2 wks (Q2W) in combination with durva (1500 mg/kg) or treme (75 or 225 mg/kg) Q4W, until confirmed disease progression or unacceptable toxicity. Tumor assessments were performed Q8W with immune-related Response Evaluation Criteria in Solid Tumors. Results: In total, 27 and 31 pts received MEDI0562 + durva or treme, across 5 dose combination cohorts (3 + 3 design), with a maximum tolerated dose of 7.5 mg MEDI0652 + 1500 mg durva and maximum administered dose of 10 mg MEDI0562 + 225 mg treme. Median duration of exposure was 12.0 (range 2.0–80.9) and 8.0 (range 2.0–42.0) wks, respectively. Two (22.5 mg MEDI10562 + durva) and 3 (2.25 mg MEDI0652 + 225 mg treme, 22.5 mg MEDI0562 + 75 and 225 mg treme) dose limiting toxicities were observed. For MEDI0562 + durva and MEDI0562 + treme groups respectively, treatment-emergent adverse events (TEAEs) were reported in 96.3% and 100% of pts; most common TEAEs were fatigue (55.6%) and pruritus (45.2%), Gr 3/4 TEAEs occurred in 74.1% and 67.7%; and MEDI0562-related AEs were reported in 20 (74.1%) and 24 (77.4%) pts. Six TEAEs in each group led to MEDI0562 discontinuation (22.2% and 19.4%, respectively), 2 led to death (renal failure [7.5 mg MEDI0562 + durva], multiple organ dysfunction syndrome [22.5 mg MEDI0562 + 225 mg treme]). Three response evaluable pts had PR (11.5% [7.5 and 22.5 mg MEDI0562 + durva, n = 26]). Median overall survival was 17.4 and 11.9 mos for MEDI0562 + durva and MEDI0562 + treme, with stable disease seen in 9 pts from each group, 34.6% vs 29.0%, respectively. Serum exposure of MEDI0562 increased dose proportionally. Post treatment serum antidrug antibody (ADA) was detected in 20 pts from MEDI0562 + durva and MEDI0562 + treme (74.1% and 71.4%, respectively). The impact of ADA on MEDI0562 pharmacokinetics was seen at all doses. Mean percentage of Ki67+CD4+ and Ki67+CD8+ memory T cells increased, while mean percentage of OX40+CD4+ memory T cells decreased following the first dose of MEDI0562 + durva or treme. Conclusions: The safety profile of MEDI0562 in combination with durva or treme was similar between groups. Clinical activity was observed with MEDI0562 + durva in pts with advanced solid tumors. Clinical trial information: NCT02705482 .

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.

Summary Background This phase 1, single-center, nonrandomized, single-arm, open-label, dose-escalation study, evaluated the tolerability of crenigacestat, a γ-secretase inhibitor as an oral Notch inhibitor in Japanese patients with advanced solid tumors. Methods The study consisted of 2 dose levels of crenigacestat (25 mg and 50 mg), administered orally 3 times per week (TIW) over a 28-day cycle until disease progression, development of unacceptable toxicity, or any other discontinuation criteria were met. The primary objective was to evaluate the tolerability and determine the recommended dose of crenigacestat for Japanese patients. Secondary objectives were to characterize the safety and toxicity, the pharmacokinetic parameters, and to document any antitumor activity of crenigacestat. Results Eleven Japanese patients with advanced solid tumors were enrolled; 4 patients (median age of 64 years) received 25 mg of crenigacestat, and 7 patients (median age of 72 years) received 50 mg of crenigacestat. Median treatment duration was 8 weeks in the 25-mg treatment arm and 4 weeks in the 50-mg treatment arm. There were no dose-limiting toxicities or dose-limiting equivalent toxicities observed. None of the patients had a complete or partial response to the treatment. One patient (14.3%) with a desmoid tumor in the 50-mg treatment arm showed tumor size shrinkage of 22.4% and had stable disease for 22.5 months. Frequent (>14%) treatment-related-adverse events in both treatment arms included diarrhea, malaise, and vomiting. Conclusions Crenigacestat was tolerated in Japanese patients but with limited clinical activity. The recommended crenigacestat dose in Japanese patients is 50 mg TIW. Trial registration: NCT02836600 (ClinicalTrials.gov) registered on July 19, 2016.

Abstract Purpose This study aimed at evaluating the effect of rucaparib on the pharmacokinetics of rosuvastatin and oral contraceptives in patients with advanced solid tumors and the safety of rucaparib with and without coadministration of rosuvastatin or oral contraceptives. Methods Patients received single doses of oral rosuvastatin 20 mg (Arm A) or oral contraceptives ethinylestradiol 30 µg + levonorgestrel 150 µg (Arm B) on days 1 and 19 and continuous doses of rucaparib 600 mg BID from day 5 to 23. Serial blood samples were collected with and without rucaparib for pharmacokinetic analysis. Results Thirty-six patients (n = 18 each arm) were enrolled and received at least 1 dose of study drug. In the drug–drug interaction analysis (n = 15 each arm), the geometric mean ratio (GMR) of maximum concentration (Cmax) with and without rucaparib was 1.29 for rosuvastatin, 1.09 for ethinylestradiol, and 1.19 for levonorgestrel. GMR of area under the concentration–time curve from time zero to last quantifiable measurement (AUC0–last) was 1.34 for rosuvastatin, 1.43 for ethinylestradiol, and 1.56 for levonorgestrel. There was no increase in frequency of treatment-emergent adverse events (TEAEs) when rucaparib was given with either of the probe drugs. In both arms, most TEAEs were mild in severity and considered unrelated to study treatment. Conclusion Rucaparib 600 mg BID weakly increased the plasma exposure to rosuvastatin or oral contraceptives. Rucaparib safety profile when coadministered with rosuvastatin or oral contraceptives was consistent with that of rucaparib monotherapy. Dose adjustments of rosuvastatin and oral contraceptives are not necessary when coadministered with rucaparib. ClinicalTrials.gov NCT03954366; Date of registration May 17, 2019.
