    Abstract: Chimeric antigen receptor (CAR)–modified T cells with anti-CD19 specificity are a highly effective novel immune therapy for relapsed/refractory acute lymphoblastic leukemia. Cytokine release syndrome (CRS) is the most significant and life-threatening toxicity. To improve understanding of CRS, we measured cytokines and clinical biomarkers in 51 CTL019-treated patients. Peak levels of 24 cytokines, including IFNγ, IL6, sgp130, and sIL6R, in the first month after infusion were highly associated with severe CRS. Using regression modeling, we could accurately predict which patients would develop severe CRS with a signature composed of three cytokines. Results were validated in an independent cohort. Changes in serum biochemical markers, including C-reactive protein and ferritin, were associated with CRS but failed to predict development of severe CRS. These comprehensive profiling data provide novel insights into CRS biology and, importantly, represent the first data that can accurately predict which patients have a high probability of becoming critically ill. Significance: CRS is the most common severe toxicity seen after CAR T-cell treatment. We developed models that can accurately predict which patients are likely to develop severe CRS before they become critically ill, which improves understanding of CRS biology and may guide future cytokine-directed therapy.

    Abstract: Pancreatic adenocarcinoma has the worst overall mortality of any solid tumor, with only 6% of patients surviving after 5 years. To evaluate the clinical implications of genomic alterations in this low cellularity tumor type, we deeply sequenced the genomes of 134 enriched pancreatic adenocarcinomas from patients who underwent potentially curative resections. Given the low neoplastic cellularity of pancreatic cancers, we enriched for neoplastic cells either by macrodissection of primary tumors or by flow-sorting of tumor nuclei, and performed deep sequencing (high coverage) of these enriched samples using next-generation sequencing approaches. We obtained a total of & gt;1Tb of sequence data, resulting in an average coverage within the target regions of & gt;200-fold for each tumor analyzed by whole-exome sequencing and & gt;750-fold for each tumor analyzed by targeted cancer gene sequencing. These approaches allowed us to identify sequence changes, including single base and small insertion or deletion mutations, as well as copy number alterations in & gt;20,000 genes in the whole-exome analyses and in 116 specific genes in the targeted analyses. These analyses revealed that somatic mutation of chromatin remodeling genes were associated with improved progression-free and overall survival. Alterations in genes with potential clinical utility were observed in a majority of cases and included alterations of AKT1, AKT2, BRCA2, ERBB2, KIT, and PIK3CA. Non-invasive liquid biopsy analyses were performed before and after surgery to evaluate the presence of circulating tumor DNA in the plasma of 83 patients. Through these approaches, we were able to diagnose early stage pancreatic tumors in the majority of patients and to detect the presence of circulating tumor DNA prior to clinical relapse. These observations provide genetic markers of clinical outcome in pancreatic cancer and suggest new avenues for personalized therapy.

    Abstract 2894: XMT-1592, a site-specific Dolasynthen-based NaPi2b-targeted antibody-drug conjugate for the treatment of ovarian cancer and lung adenocarcinoma

    Abstract: The Dolasynthen platform incorporates the highly potent anti-mitotic agent auristatin F-HPA (AF-HPA), with its associated DolaLock mechanism of controlled bystander effect, and enables the synthesis of antibody-drug conjugates (ADCs) with precise control of the drug-to-antibody ratio (DAR) and site-specific bioconjugation. XMT-1592 is a novel ADC comprised of an anti-NaPi2b antibody and Dolasynthen, conjugated in a site-specific manner to yield DAR 6. NaPi2b, also known as SLC34A2, is a transmembrane sodium-phosphate transporter that is broadly expressed on tumor cells in ovarian carcinoma, NSCLC lung adenocarcinoma and other tumor types. Recent studies have shown that NaPi2b expression is enriched in the EGFR and KRAS mutant subtypes of lung adenocarcinoma. Binding studies showed a specific, high-affinity interaction of XMT-1592 with NaPi2b that was not affected by conjugated Dolasynthen. XMT-1592 elicited potent and specific in vitro cytotoxicity against NaPi2b-expressing ovarian carcinoma cells. XMT-1592 exhibited potent and specific in vivo activity in NaPi2b-expressing tumor xenografts derived from ovarian carcinoma or lung adenocarcinoma. Consistent with the targeted delivery benefits of the ADC approach, XMT-1592 yielded high and sustained concentrations of AF-HPA to tumors but not normal tissues. To evaluate the benefits of site-specific bioconjugation of Dolasynthen, we conducted in vitro and in vivo comparisons of XMT-1592 to a stochastically conjugated version of the ADC. XMT-1592 had improved in vivo activity, pharmacokinetics, and clinical pathology relative to its stochastic counterpart. Taken together, these results support XMT-1592 as a development candidate for the treatment of NaPi2b-expressing tumors. Citation Format: Shawn Fessler, Anouk Dirksen, Scott D.

    Abstract A252: A phase 1 study of ARRY-382, an oral inhibitor of colony-stimulating factor-1 receptor (CSF1R), in patients with advanced or metastatic cancers.

    Abstract: Introduction: Within the tumor microenvironment, CSF1R signaling is thought to play an important role in recruitment and differentiation of tumor-associated macrophages and osteoclasts, promoting disease progression through suppression of anti-tumor immune response, promotion of angiogenesis, tumor cell metastasis and tumor-induced osteolysis. ARRY-382 is a potent, highly selective, oral inhibitor of CSF1R. This Phase 1 dose-escalation study was designed to determine the maximum tolerated dose (MTD) and to assess the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of ARRY-382 in patients (pts) with advanced or metastatic cancers refractory to standard treatment. Methods: Pts received ARRY-382 orally once daily (QD) in 28-day cycles. Study design included an initial accelerated titration phase, followed by 3+3 dose escalation and an expansion phase. Safety was assessed by adverse events (AEs), ECGs, clinical laboratory tests, physical exams and vital signs. PK parameters were estimated based on serial plasma PK samples. Levels of pERK in pt monocytes stimulated with CSF1 ex vivo, circulating CD14dim/CD16+ nonclassical monocytes (NCM) and CSF1 were evaluated as markers of CSF1R inhibition. Urinary collagen type 1 cross-linked N[[Unable to Display Character: & #8209;]]telopeptide (NTX) was evaluated as a marker of bone turnover. Results: Twenty-six pts received ARRY-382 at doses ranging from 25 to 500 mg QD. The MTD of ARRY-382 was 400 mg QD. Dose-limiting toxicities were increased creatine kinase (CK), increased AST and pyrexia (1 pt each, all Grade 3). The most common drug-related AEs were fatigue (42%), increased CK (27%), nausea (23%), decreased appetite (15%) and vomiting (12%). Grade 3/4 AEs in & gt;1 pt were increased CK (23%), pneumonia (15%), anemia (8%) and vomiting (8%). Increases in ARRY-382 exposure were approximately dose proportional. At the MTD, a Cmax of 3.06 µg/mL was achieved with a Ctrough & gt; 1 µg/mL after repeated dosing. Doses ≥ 200 mg QD resulted in & gt; 80% mean reduction from Baseline in monocyte pERK, consistent with exposures above the ARRY-382 IC50 value. The PD activity of ARRY-382 was consistent with CSF1R inhibition. Reductions in NCM were observed at doses ≥ 200 mg QD, with a 96% mean decrease from Baseline observed at the MTD. Reductions in urinary NTX were observed at doses ≥ 50 mg QD. Five of 7 pts with elevated urinary NTX at Baseline experienced reductions to within the normal range in the first cycle, including 3 pts with bone metastases. Increases in CSF1 appeared dose-dependent with ∼28-fold maximal increase from Baseline observed at the MTD in the first cycle. No objective responses were observed, although 4 pts (15%) experienced stable disease which lasted & gt; 3 months for 2 pts. Conclusions: ARRY-382 was generally well tolerated in pts with advanced or metastatic cancers. Exposure and PD activity of ARRY[[Unable to Display Character: & #8209;]]382 indicate that CSF1R was significantly inhibited at tolerated doses.
