3510 Background: Pyrotinib is a potent, irreversible tyrosine kinase inhibitor (TKI) that blocks signal transduction through the erythroblastic leukemia viral oncogene homolog (erbB) receptors, which has previously demonstrated promising antitumor activity in patients (pts) with breast cancers. We studied the safety and efficacy of pyrotinib in pts with non-small cell lung cancer (NSCLC) and other solid tumors with activating human epidermal growth factor receptor 2 ( HER2, ERBB2) alterations. Methods: This is an open-label, multicenter phase 1 dose expansion basket trial of pyrotinib given 400mg oral daily at 28-day cycles. Expansion cohorts included pts with HER2-mutant NSCLC and advanced solid tumors with HER2 mutation or amplification. HER2 testing was conducted using next generation sequencing or fluorescence in situ hybridization. Primary endpoints included toxicities as evaluated by NCI CTCAE v5.0, and overall response rate (ORR) as evaluated by RECIST v1.1. Secondary objectives included progression-free survival (PFS). Results: A total of 62 pts were enrolled. The median age was 67 (range 40 – 86 years), 61% were female and the median lines of prior systemic therapy was 3 (range 1-11). There were no treatment related deaths. The most common adverse events were diarrhea (96.8%), nausea (82.3%) and vomiting (41.9%). The only ≥ grade 3 treatment related toxicity was diarrhea (24.2%). Prophylactic anti-diarrhea treatment was introduced to facilitate continuation of pyrotinib. At the Jan 13, 2020 cut-off, 24 pts with HER2-mutant NSCLC (20, i.e. 65% of which were the A775_G776insYVMA mutation) and 18 pts with HER2-mutant or amplified solid tumors completed end of Cycle 2 imaging scan and were evaluable for tumor responses. The ORR was 19% (8/42, 95% CI 7-31%); confirmed responses include a complete response (CR) and 3 partial responses (PRs) in HER2-mutant NSCLC, and 4 PRs in HER2-amplified cholangiocarcinoma, ovarian, endometrial and salivary gland carcinomas. There were 7 stable disease ≥ 6 months. Median progression-free survival was 5.4 months (95% CI 4.4-7.3). Conclusions: Pyrotinib demonstrated a manageable safety profile and encouraging efficacy in pts with heavily pre-treated HER2-mutant NSCLC. Furthermore, it is the first TKI to produce durable responses in pts with HER2-amplified biliary tract, ovarian, endometrial and salivary gland cancers. These results warrant further clinical development of pyrotinib. Clinical trial information: NCT02500199 .

Purpose CD27, a costimulatory molecule on T cells, induces intracellular signals that mediate cellular activation, proliferation, effector function, and cell survival upon binding to its ligand, CD70. Varlilumab is a novel, first-in-class, agonist CD27 antibody that stimulates the CD27 pathway, which results in T-cell activation and antitumor activity in tumor models. This first-in-human, dose-escalation and expansion study evaluated the safety, pharmacology, and activity of varlilumab in patients with advanced solid tumors. Methods In a 3 + 3 dose-escalation design (n = 25), patients received a single dose of varlilumab (0.1, 0.3, 1.0, 3.0, or 10 mg/kg intravenously) with a 28-day observation, followed by up to five multidose cycles (one dose per week for 4 weeks), depending on tumor response. Expansion cohorts were initiated at 3.0 mg/kg in patients with melanoma (n = 16) and renal cell carcinoma (RCC; n = 15). Primary objectives were to assess the safety and the maximum tolerated and optimal biologic doses of varlilumab. Secondary objectives were to evaluate the pharmacokinetics, pharmacodynamics, and clinical antitumor activity of varlilumab. Results Exposure to varlilumab was linear and dose proportional across dose groups. Only one patient experienced a dose-limiting toxicity—grade 3 transient asymptomatic hyponatremia at the 1.0-mg/kg dose level. Treatment-related adverse events were generally grade 1 or 2 in severity. Evidence of biologic activity consistent with CD27 stimulation—chemokine induction, T-cell stimulation, regulatory T cell depletion—was observed at all dose levels. A patient with metastatic RCC experienced a partial response (78% shrinkage, progression-free survival > 2.3 years). Eight patients experienced stable disease > 3 months, including a patient with metastatic RCC with progression-free survival of > 3.9 years. Conclusion Dose escalation of varlilumab to 10 mg/kg was well tolerated without identification of a maximum tolerated dose. Varlilumab was biologically and clinically active.

9065 Background: Cediranib, a pan-vascular endothelial growth factor receptor tyrosine kinase inhibitor, suppresses expression of BRCA1, BRCA2, and RAD51 and increases sensitivity of tumors to poly-(ADP-ribose) polymerase (PARP) inhibitors in vitro. Olaparib, a PARP inhibitor, demonstrated clinical efficacy in patients with advanced solid tumors carrying a germline BRCA mutation. We therefore tested the anti-tumor activity of cediranib and olaparib combination in patients (pts) with advanced solid tumors. Here, we report the data from the SCLC cohort. Methods: This multi-institutional, two-stage, phase 2 study enrolled pts with metastatic SCLC previously treated with a minimum of one prior line of platinum-based chemotherapy in advanced setting. Patients were treated with cediranib 30mg po daily plus olaparib 200mg po BID until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (ORR) by RECIST v1.1. Baseline tumor biopsies were obtained for biomarker analyses. Results: Baseline characteristics of the 25 pts enrolled are summarized below. The overall ORR rate was 28% (95% CI: 0.104,0.456). Median duration of response was 3.8 months (mos). Six of 8 pts had an objective response lasting longer than 3 mos up to 10.3 months. Disease control rate (# of pts with CR, PR or SD / # evaluable pts) was 88% (95% CI: 0.75,1.01). Median progression free survival was 4.1 mos (95% CI: 2.3, 6.2). Median OS was 5.5 mos (95% CI: 3.4, NA). Grade 3/4 adverse events (G3/4 AEs), irrespective of attribution, occurred in 14 of 25 (56%). G3/4 AEs occurring in > 10% of pts were hypertension (21%), fatigue (17%) and weight loss (13%). Conclusions: The cediranib/olaparib combination resulted in promising clinical activity with ORR of 28% in biomarker-unselected pts with platinum-pretreated SCLC. The regimen required prompt initiation of antihypertensives, but AEs were overall manageable. Analyses of mutation status in homologous recombination DNA repair genes are going and will be correlated with clinical activity. Clinical trial information: NCT02498613. [Table: see text]

Abstract Background While the introduction of checkpoint inhibitors (CPIs) as standard of care treatment for various tumor types has led to considerable improvements in clinical outcome, the majority of patients still fail to respond. Preclinical data suggest that stereotactic body radiotherapy (SBRT) could work synergistically with CPIs by acting as an in situ cancer vaccine, thus potentially increasing response rates and prolonging disease control. Though SBRT administered concurrently with CPIs has been shown to be safe, evidence of its efficacy from large randomized trials is still lacking. The aim of this multicenter randomized phase II trial is to assess whether SBRT administered concurrently with CPIs could prolong progression-free survival as compared to standard of care in patients with advanced solid tumors. Methods/design Ninety-eight patients with locally advanced or metastatic disease will be randomized in a 1:1 fashion to receive CPI treatment combined with SBRT (Arm A) or CPI monotherapy (Arm B). Randomization will be stratified according to tumor histology (melanoma, renal, urothelial, head and neck squamous cell or non-small cell lung carcinoma) and disease burden (≤ or > 3 cancer lesions). The recommended SBRT dose is 24Gy in 3 fractions, which will be administered to a maximum of 3 lesions and is to be completed prior to the second or third CPI cycle (depending on CPI treatment schedule). The study’s primary endpoint is progression-free survival as per iRECIST. Secondary endpoints include overall survival, objective response, local control, quality of life and toxicity. Translational analyses will be performed using blood, fecal and tissue samples. Discussion: The CHEERS trial will provide further insights into the clinical and immunological impact of SBRT when combined with CPIs in patients with advanced solid tumors. Furthermore, study results will inform the design of future immuno-radiotherapy trials. Trial registration Clinicaltrials.gov identifier: NCT03511391. Registered 17 April 2018.

Purpose To evaluate MK-8242 in patients with wild-type TP53 advanced solid tumors. Patients and Methods MK-8242 was administered orally twice a day on days 1 to 7 in 21-day cycles. The recommended phase II dose (RP2D) was determined on the basis of safety, tolerability, pharmacokinetics (PK), and by mRNA expression of the p53 target gene pleckstrin homology-like domain, family A, member 3 ( PHLDA3). Other objectives were to characterize the PK/pharmacodynamic (PD) relationship, correlate biomarkers with response, and assess tumor response. Results Forty-seven patients received MK-8242 across eight doses that ranged from 60 to 500 mg. Initially, six patients developed dose-limiting toxicities (DLTs): grade (G) 2 nausea at 120 mg; G3 fatigue at 250 mg; G2 nausea and G4 thrombocytopenia at 350 mg; and G3 vomiting and G3 diarrhea at 500 mg. DLT criteria were revised to permit management of GI toxicities. Dosing was resumed at 400 mg, and four additional DLTs were observed: G4 neutropenia and G4 thrombocytopenia at 400 mg and G4 thrombocytopenia (two patients) at 500 mg. Other drug-related G3 and G4 events included anemia, leukopenia, pancytopenia, nausea, hyperbilirubinemia, hypophosphatemia, and anorexia. On the basis of safety, tolerability, PK, and PD, the RP2D was established at 400 mg (15 evaluable patients experienced two DLTs). PK for 400 mg (day 7) showed Cmax 3.07 μM, Tmax 3.0 hours, t1/2 (half-life) 6.6 hours, CL/F (apparent clearance) 28.9 L/h, and Vd/F (apparent volume) 274 L. Blood PHLDA3 mRNA expression correlated with drug exposure ( R2 = 0.68; P < .001). In 41 patients with postbaseline scans, three patients with liposarcoma achieved a partial response (at 250, 400, and 500 mg), 31 showed stable disease, and eight had progressive disease. In total, 27 patients with liposarcoma had a median progression-free survival of 237 days. Conclusion At the RP2D of 400 mg twice a day, MK-8242 activated the p53 pathway with an acceptable safety and tolerability profile. The observed clinical activity (partial response and prolonged progression-free survival) provides an impetus for further study of HDM2 inhibitors in liposarcoma.
