2538 Background: Trebananib is a first-in-class peptibody (peptide-Fc fusion protein) that selectively inhibits Angiopoietin 1 and Angiopoietin 2 to inhibit interaction with the Tie2 receptor tyrosine kinase and prevent angiogenesis by a VEGF independent mechanism. A pediatric phase 1 trial was performed to define the dose limiting toxicities (DLT), maximum tolerated dose (MTD) and pharmacokinetics (PK) of trebananib. Methods: Trebananib was administered as a weekly 30 - 60 minute IV infusion. Three dose levels (10, 15 or 30 mg/kg/dose) were evaluated using a rolling-six design. PK sampling and analysis of peripheral blood biomarkers was performed during the first 4 weeks of therapy. Results: Fifteen eligible patients (14 evaluable for toxicity) with a median age of 14 yrs (range, 3 to 20) and diagnoses of neuroblastoma (n=4), rhabdomyosarcoma (n=3), Ewing sarcoma (n=3), osteosarcoma (n=2), other soft tissue sarcoma (n=2), or nasopharyngeal carcinoma (n=1) have been enrolled. There were no DLTs observed at either the 10 mg/kg (n=6 pts) or 15 mg/kg (n=3 pts) dose. 1/6 pts receiving 30 mg/kg/dose developed DLT (venous thrombosis at a central line site). Non-dose limiting grade 3 or 4 toxicities included lymphopenia (n=2) hypertension (n=1), and neutropenia (n=1). Response in evaluable patients after eight weeks of therapy included stable disease (n=6 pts) and progressive disease (n=7 pts). PK were linear over the 3 dose levels, with t1/2 and Clpvalues of 69±18 h and 1.6±0.5 ml/h/kg, respectively. Conclusions: Trebananib is well tolerated in pediatric patients with recurrent or refractory solid tumors with recommended Phase 2 dose of 30 mg/kg. Correlative biology studies will be presented. Further study is planned to evaluate tolerability and changes in vascular permeability in patients with primary CNS tumors. Clinical trial information: NCT01538095.
Treatment of cancer and cancer stem cells by blocking the Notch pathway.
Authors: Epenetos Agamemnon A. , Stylianou Spyros 
Published: March 2020

2539 Background: Current treatments often fail to cure cancer. It has been shown (JCO, 26, June 10, 2008) that Cancer Stem Cells, (CSCs), are responsible for the initiation, metastasis and recurrence of many cancers and may be a key reason for the failure of current therapies.The NOTCH pathway is an important pathway in the development of many tumors ,and cancer stem cells in particular. Methods: We have generated genetically and synthetically a hybrid protein (Antp-DNMAML) .consisting of the truncated version of MastermindElike (MAML) that behaves in a dominant negative (DN) fashion inhibiting Notch activation, and the cell penetrating peptide Antennapedia (Antp). Results: It is demonstrated that Antp-DNMAML translocates into the nucleus and suppresses Notch activation. Attenuation of Notch signaling with AntpEDNMAML reverts the transformed phenotype, inhibits the anchorageEdependent growth, induces self contact inhibition and apoptosis in highly tumorigenic epithelial human breast cancer cells. More significantly, we provide direct evidence that inhibiting Notch signaling at the transcriptional level with the Antp-MAML protein ,suppresses the expression of downstream Notch targets, induces tumor cell apoptosis, and inhibits or eliminates human tumor growth in nude mice, without organ or systemic toxicity. Conclusions: Intracellular delivery of dominant-negative transcription complex proteins using the Antp platform is a new and specific approach for cancer therapy.
Effects of a soluble activin type 2B receptor Fc fusion protein (STM 217) in TOV-21G, a mouse xenograft model of clear cell ovarian cancer.
Authors: Lu John , Haqq Christopher M. , Han HQ 
Published: March 2020

2541 Background: Response rate and survival with the clear cell subtype of ovarian cancer is has not been improved by the introduction of platinum and taxane chemotherapy. Elevated serum activin is associated with inferior ovarian cancer survival, suggesting that activin inhibition may provide a new treatment strategy. STM 217 (recombinant hu-sActR2B-Fc) is a potent (IC50 < 1nM) inhibitor of activin and myostatin signaling that was tested for anti-ovarian tumor activity. Methods: Athymic nude mice received TOV-21g (clear cell ovarian cancer model) xenografts in the abdominal flank region and after 14 days, weekly subcutaneous STM 217 was administered alone or in combination with 5-fluorouracil (5-FU). Mice were monitored for body weight and tumor volume. Results: After 52 days from tumor cell injection, STM 217 treatment resulted in a statistically significant 43% (p<0.0001) tumor growth reduction, versus the vehicle-treated tumor bearing group tested using ANOVA. In the combination efficacy experiment, 5-FU monotherapy resulted in a 47% (p<0.0001) tumor growth reduction, and the combination of STM217 and 5-FU together resulted in a 73% (p<0.0001) tumor growth reduction. During the course of the study, body weight of the mice receiving STM 217 increased by 26%, mice receiving STM 217 and 5-FU increased by 22%, while control tumor bearing mice receiving vehicle exhibited a 10% body weight loss. Conclusions: Our study demonstrates that inhibition of activin signaling by use of a ligand trap results in antitumor activity, both as a monotherapy, and that additive activity was observed in combination with chemotherapy. Increases in body weight were not impaired by concomitant administration of 5-FU chemotherapy. This study suggests that a phase 1 clinical trial of activin inhibition in metastatic ovarian cancer is warranted.

2550 Background: Aldoxorubicin is a novel drug that covalently binds to albumin in the circulation with release in low pH environments. Preclinical studies in pancreatic and ovarian tumor xenograft models demonstrated that aldoxorubicin plus doxorubicin administered at 50% of their MTD provided complete and prolonged tumor remission in these models with less toxicity than each drug administered at their MTD. We evaluated the toxicity profile of a fixed dose of doxorubicin and escalating doses of aldoxorubicin in subjects with advanced solid tumors. Methods: Phase 1b open label, dose-escalation study of aldoxorubicin administered at either 175, 240 or 320 mg/m2 (130, 180, or 240 mg/m2 doxorubicin equivalents) iv + 35 mg/m2doxorubicin iv, both on Day 1 of 21 day cycles, for up to 8 cycles. The MTD is the dose level immediately below where 2/6 subjects experience a dose limiting toxicity (DLT) , or the maximum dose of 320 mg/m2aldoxorubicin. Additional subjects may be enrolled at the MTD to provide more safety data. Results: 10 subjects have been treated as of January 21, 2013. No DLT was observed and the MTD was defined as 320 mg/m2 aldoxorubicin and 35 mg/m2 doxorubicin iv administered on Day 1 of 21 day cycles. A median of 4.5 cycles have been received. 3/10 subjects were terminated due to either progressive disease (2) or death (1). No subject was terminated due to an adverse event. Grade 3 or 4 neutropenia was seen at all dose levels (8/10 subjects). 4/10 subjects exhibited grade 3 or 4 thrombocytopenia and 3/10 subjects had grade 3 or 4 anemia. Neutropenic fever occurred in 3/10 subjects. Other grade 3/4 adverse events seen in 2 or fewer subjects included fatigue, increased liver enzymes and dehydration. No significant mucositis or cardiotoxicity was observed. At this time the best response has been stable disease in 6/10 subjects and a partial response in 1 subject (malignant fibrous histiocytoma). Conclusions: The combination of aldoxorubicin (320 mg/m2)) + doxorubicin (35 mg/m2) can be safely administered to subjects with solid tumors. Hematologic toxicity is common and can be controlled with growth factors. The dose of aldoxorubicin is 90% of the MTD of aldoxorubicin administered as a single agent. Thus, doxorubicin does not appear to add to the toxicity of this combination. Clinical trial information: NCT01673438.

2554 Background: Satraplatin is an orally bioavailable platinum analog. Based on pre-clinical activity (IC500.02-8 µg/ml) including activity in cisplatin resistant cell lines, and clinical activity without neuro-, nephro-, or ototoxicity in adults with refractory tumors, we developed a phase 1 trial to determine the toxicities, maximum tolerated dose (MTD), and PKs of satraplatin in children with refractory solid tumors. Methods: Satraplatin (10 and 50 mg capsules) was administered orally once daily on days 1 - 5 of a 28 day cycle to cohorts of 3-6 patients (pts) at 60 mg/m2/dose (DL 1) and 80 mg/m2/dose (DL 2). Plasma ultrafiltrate (PUF) platinum was measured using atomic absorption spectroscopy during cycle 1 for PK analysis. Results: 9 pts [5 male, 4 female, median age 17 years (range 8-19)] with malignant glioma (n=4), ependymoma (n=2), medulloblastoma (n=1), osteosarcoma (n=1), or hepatoblastoma (n=1) received 1-10+ cycles (median 2). The MTD was exceeded at DL 2 as 2/4 pts had dose limiting toxicities (DLT) of delayed and prolonged myelosuppression (grade 3 thrombocytopenia, n=1; grade 3-4 neutropenia, n=2). 0/5 pts at DL 1 had DLTs. Grade 1 ototoxicity was seen in 1 pt at cycle 10. Non-DLTs included myelosuppression, gastrointestinal toxicities, fatigue, headache, liver enzyme elevation, and electrolyte abnormalities. No objective responses were observed, but 1 pt with gliomatosis cerebri has had radiographic stable disease through cycle 10+. Satraplatin mean exposure (AUC) and peak concentration (Cmax) were similar at both dose levels [day 1 PUF AUC0-24h 1.22 ± 0.55 µg/ml*h at DL1 (n=3), 1.02 ± 0.45 µg/ml*h at DL2 (n=3); Cmax0.17 ± 0.08 µg/ml at DL 1 (n=3), 0.16 ± 0.05 µg/ml at DL 2 (n=3)]. Terminal half-life was 14 ± 6 h and apparent clearance was 76 ± 29 L/h (n=6). Conclusions: The MTD of oral satraplatin in children with solid tumors is 60 mg/m2/dose daily x 5 q28 days. The toxicity profile was similar to adults, and delayed myelosuppression was DLT. Satraplatin exposure appears higher in pediatric pts compared to adults (PUF AUC0-24h 0.25-0.47 µg/ml*h at 60-80 mg/m2/dose). DL 1 will be expanded to gain additional experience regarding toxicities and PKs in a broader age range. Clinical trial information: NCT01259479.

2567 Background: MLN0128 (INK128) is an investigational oral, potent, and highly selective inhibitor of mammalian target of rapamycin complex 1 and 2 (mTORC1/2) currently in clinical investigation. In the phase1 study INK128-001, MLN0128 was administered once daily (QD), once weekly (QW), QDx3D/week, and QDx5D/week, with respective MTDs of 6, 40, 16, and 10 mg. To guide selection of dose/schedule for further investigation, PD modulation in skin (pS6, p4EBP1, pNDRG1, pPRAS40) was put into context of clinical PK in INK128-001. A preclinical translational dynamic-PK efficacy model was used to describe the relationship and determine PK drivers of efficacy in tumor xenograft models. This model was implemented using human PK parameters to predict tumor volume-time curves, which was utilized to help determine the optimal MLN0128 dose/schedule. Methods: Phoenix NLME v1.1 was used for compartmental modeling of clinical and preclinical PK data, and modeling the preclinical PK-efficacy relationship of MLN0128. PD activity in skin was measured by immunohistochemistry, reported as H scores. Tumor growth curves were simulated using NONMEM v7.2; predicted tumor growth curves were plotted in S-Plus v8.1. Results: Clinical skin PD data suggests exposure dependent inhibition of pS6, and p4EBP1. A two compartment PK model adequately described the PK characteristics of MLN0128 [mean (%CV) ka: ~5.305 h-1 (114), k12: ~0.490 h-1(85), k21: ~0.67 h-1(69), V/F: ~180 L (44), Tlag: 0.317 h (73)]. Simulation of human tumor volume-time curves suggest efficacy is dependent on schedule and that MLN0128 administered in more frequent schedules (QD, QDx5D) provides stronger antitumor effect vs less frequent schedules (QW, QDx3D). Conclusions: The results indicate that per unit MLN0128 plasma exposure, QD and QDx5D may be optimal in comparison with QDx3D and QW dosing. However, these results will also need to be put into context with the overall safety profile and respective MTDs and RP2Ds for each schedule with their resultant achievable total cycle dose by schedule.

2571 Background: Continuous 400 mg daily vorinostat (V) is effective treatment for cutaneous T-cell lymphoma, but has displayed erratic activity in combination therapy for solid tumors. Short-course high-dose vorinostat may have a better therapeutic index for solid tumors, but dose/exposure/PD relationships have not been tested in sufficiently powered studies. Methods: Patients (pts) were randomized to either V 1600 mg daily, days (d) 1-3 then 400 mg d8-10 or 400 mg d1-3 then 1600 mg d8-10 with complete PK sampling on d3 and d10 to determine the increase in Cmax upon increasing V from 400 to1600 mg. To assess safety and tolerability of high dose V added to carboplatin, pts then received high dose V d15-17 with carboplatin AUC 5 on d17; this combination was repeated every 21d thereafter. Platelet counts were determined weekly. To detect with 80% power a difference in vorinostat Cmax between 400 and 1600 mg required at least 10 pts in each sequence. In vitro studies of gene expression in solid tumors suggested as a secondary endpoint the frequency of pts achieving Cmax > 1000 ng/mL. Results: 24 pts (11 men/13 women) enrolled between April 2011 and March 2012 and were evaluable for study endpoints. No sequence dependence of change in Cmax was detected. Cmax for V 1600 mg was nearly double that for 400 mg (1184+/-631 vs. 616+/-442 ng/mL, p < 0.001). The PD effect on platelets (d10) was greater for the higher dose (median -76 vs. -14 K/µL, p= 0.02). There were no dose limiting toxicities. Of 24 pts, 11 achieved Cmax > 1000 ng/mL. Conclusions: The 1600 mg dose of vorinostat results in a higher Cmax than 400 mg and greater PD effect than 400 mg and is tolerable in combination with carboplatin. The carboplatin/vorinostat doublet serves as a DNA-damaging/epigenetic modifier module to be combined in more complex regimens. Clinical trial information: NCT01281176.

2573 Background: IMGN853 is an antibody-drug conjugate (ADC) comprising a folate receptor 1 (FOLR1)-binding antibody and the potent maytansinoid, DM4. FOLR1 is over-expressed on many solid tumors, particularly EOC, endometrial cancer, non-small cell lung cancer (NSCLC), and clear-cell renal cell cancer. Methods: The primary study objectives are to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Secondary objectives include evaluation of safety, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy. In dose escalation, patients with any type of FOLR1-expressing, refractory solid tumor may be enrolled. Once the MTD is defined, 3 expansion cohorts will evaluate patients with (1) primary platinum refractory or resistant EOC; (2) relapsed/refractory EOC, amenable to biopsy, and (3) relapsed/refractory NSCLC. Cohorts 2 and 3 will have IMGN853 PD assessment by pre-and post-dose tumor biopsy and by FLT-PET imaging, respectively. IMGN853 is given intravenously (IV) on Day 1 of each 21-day cycle. During dose escalation, an accelerated titration design was used. Responses are assessed using RECIST and GCIG criteria (as appropriate). Results: Eleven patients have been enrolled across 6 dose levels ranging from 0.15 to 5.0 mg/kg: 7 patients with EOC and 4 patients with endometrial cancer. No study drug-related serious adverse events (SAEs) or dose-limiting toxicity (DLT) have been reported. Among these 11 patients, 3 patients reported adverse events (AEs) considered study drug related; these were mild or moderate. At the 3.3 mg/kg dose level, one patient with serous EOC had an 82% reduction in CA125 (confirmation pending). The other 2 patients at this dose level, one with EOC and one with endometrial cancer, have stable disease. Drug exposure has been measured in 8 patients and has been found to generally increase linearly, with a half life at 3.3 mg/kg (3 patients) of approximately 4 days. Conclusions: IMGN853 is well tolerated at doses up to 3.3 mg/kg. Safety evaluation continues at 5 mg/kg and dose escalation is ongoing. Clinical trial information: NCT01609556.

2581 Background: Progression-free survival (PFS) and response to EGFR tyrosine kinase inhibitors (TKIs) vary in p with NSCLC driven by EGFR mutations. In our experience, high BRCA1 mRNA expression was associated with shorter PFS in EGFR-mutant p treated with erlotinib. We hypothesized that since olaparib downregulates BRCA1 expression, the addition of olaparib to gefitinib could improve PFS in these p. Methods: This is a Phase IB dose escalation study to identify the maximum tolerated dose (MTD), dose limiting toxicity (DLT), pharmacokinetics, and clinical activity of orally administered olaparib in combination with gefitinib in EGFR-mutant advanced NSCLC p. In a standard 3+3 design, p were treated with gefitinib 250mg once daily plus olaparib tablets at escalating doses ranging from 100mg BID to 250mg TDS during a 28-day cycle. Results: 18 p have been included across four dose levels of olaparib: 100mg BID (3), 200mg BID (6), 200mg TDS (3) and 250mg TDS (6). Median age, 69; male, 4; PS 0, 17; EGFR TKI treatment-naïve, 10. Toxicities: anemia (66.6%), leucopenia (33.3%), nausea (33.3%), diarrhea (33.3%), asthenia (27.7%), rash (22.2%) vomiting (11%), decreased appetite (16%), and hyperlipasemia (5.5%). Most toxicities were G1-2; G3 drug-related events included leucopenia (1) and anemia (3). No DLT at dose levels 1, 2, and 3; 1 DLT at dose level 4 (G3 anemia and repeated blood transfusion within 4-6 weeks). Few dose reductions or interruptions were needed. 1 p died due to pulmonary embolism unrelated to treatment. Partial responses (PR) were observed in 7 p (41.1%), all EGFR TKI-naïve; stable disease (SD) in 7 (41.1%), most previously treated; progressive disease (PD) in 3 (17.6%), all previously treated. Durable PR and SD were observed in EGFR TKI-naïve and previously treated p. 8 patients are still on treatment. Enrollment to dose level 4 will be completed in February 2013. Conclusions: This phase IB trial of gefitinib plus olaparib, has confirmed the activity and tolerability of the combination. The final recommended dose of olaparib is expected to be between 200 and 250 mg TDS. A phase II randomized trial in treatment-naïve EGFR-mutant advanced NSCLC will be opened in 2013. Clinical trial information: NCT0151317.

2585 Background: Rucaparib, a potent, oral small molecule inhibitor of poly (ADP-ribose) polymerase (PARP) 1 and -2, is being developed for treatment of homologous recombination repair deficient (HRD) ovarian cancer. This study evaluated oral rucaparib as monotherapy. Primary objectives were to define maximum tolerated dose (MTD), recommended Phase 2 dose (RP2D), and PK of continuous oral rucaparib. Methods: A standard 3+3 dose escalation design was used. Intra-patient dose escalation was allowed. Patients (pts) aged ≥18 with advanced solid tumor that progressed on standard treatments were recruited. Rucaparib was taken orally qd or bid until disease progression. Plasma PK assessments included full profile, trough levels, and food effect. Results: 29 pts (median age 52 yrs [range 21-71]; 26 female; 15 ECOG PS=0; 17 breast cancer (BC), 7 ovarian/peritoneal cancer (OC), 5 other tumor) were enrolled in 6 dose cohorts to date (40, 80, 160, 300 and 500 mg qd, 240 mg bid). Evaluation of 360 mg bid rucaparib is nearly complete. No DLTs have occurred and no pts have discontinued treatment due to toxicity. Treatment-related adverse events (primarily CTCAE grade 1-2) reported in ≥2 of 29 pts include fatigue (n=5), anorexia (n=3), nausea (n=3), vomiting (n=3), and diarrhea (n=2). To date, two pts (1 OC, 1 BC; both BRCA1mut) treated with 300 mg qd rucaparib achieved PR at wk 6; both are ongoing in wk 17. An additional 10 pts (5 OC, 4 BC, 1 CRC; 7 BRCAmut, 2 BRCAunk, 1 BRCAwt) achieved best response of stable disease (SD) >12 wks thus far; 4 pts (3 OC, 1 BC) are ongoing at 17 (n=2) and 30 (n=2) wks. Overall disease control rate (CR+PR+SD>12 wks) in OC pts across all dose levels was 86% (6/7). Dose proportional PK was observed up to 500 mg qd with mean t1/2 of 15 h (range 4.3 - 29 h). Following qd dosing, steady state was achieved by Day 8. As expected, bid dosing increased trough levels above 2 µM target with low interpatient variability. Conclusions: Continuous oral rucaparib is very well tolerated, with encouraging clinical activity, including objective responses and durable SD, observed during dose-escalation. Once confirmed, the RP2D will be evaluated in platinum-sensitive OC pts with a gBRCA mutation. Clinical trial information: NCT01482715.
