Abstract
Abstract
Background: Improving outcomes for patients (pts) with triple-negative breast cancer (TNBC) remains a high unmet need. Immune checkpoint inhibitors (ICIs) + chemotherapy (chemo) and single-agent sacituzumab govitecan, a trophoblast cell-surface antigen 2–targeted antibody-drug conjugate coupled to SN38 via a proprietary, hydrolysable linker, are approved in newly diagnosed pts with programmed death-ligand 1 (PD-L1)–positive tumors and pts who received ≥2 prior systemic therapies (≥1 for metastatic disease), respectively. However, additional options are urgently needed, particularly for pts with tumors that do not express PD-L1 and for those with progression on chemo ± ICI. Magrolimab is an antibody blocking CD47, a “don’t eat me” signal overexpressed on cancer cells, including TNBC, inducing tumor phagocytosis by macrophages. Magrolimab has shown preclinical activity and promising clinical efficacy in hematologic and solid tumors. Chemo agents, including taxanes, can enhance prophagocytic signals on tumor cells, leading to the potential for synergistic antitumor activity with magrolimab. This study is evaluating the safety/tolerability and efficacy of magrolimab in combination with nab-paclitaxel/paclitaxel or with sacituzumab govitecan in unresectable locally advanced/metastatic TNBC. Trial Design: This open-label, 2-cohort (C) study consists of safety run-in and phase (ph)2 portions evaluating nab-paclitaxel/paclitaxel (choice) + magrolimab (safety run-in) or ± magrolimab (ph2, randomized 1:1) in pts with untreated, advanced/metastatic TNBC ineligible for ICI (C1) and magrolimab + sacituzumab govitecan (safety run-in and ph2) in pts with advanced TNBC who received 1 prior systemic treatment in the metastatic setting (C2). Stratification factors for C1 are neoadjuvant and/or adjuvant taxane therapy, liver metastases, and nab-paclitaxel vs paclitaxel. In both cohorts, magrolimab will be administered intravenously (IV) in de-escalating doses to establish the recommended ph2 dose (RP2D). Nab-paclitaxel/paclitaxel and sacituzumab govitecan will be administered IV per standard of care. Eligibility Criteria: Eligible pts are ≥18 y with PD-L1–negative, untreated, unresectable locally advanced/metastatic TNBC (C1) or unresectable locally advanced/metastatic TNBC who received 1 prior line of therapy in the advanced setting, including a taxane and an ICI if PD-L1 positive (C2), with measurable disease per RECIST v1.1. Exclusion criteria include active central nervous system disease, red blood cell transfusion dependence, or prior treatment with CD47/signal regulatory protein α–targeting agents for both cohorts. Additional exclusions are disease progression within 6 months of (neo)adjuvant therapy or rapid visceral progression and/or symptomatic disease, for which single-agent chemo would not be appropriate (C1); chronic inflammatory bowel disease and a history of bowel obstruction or gastrointestinal perforation within 6 months of enrollment, prior treatment with topoisomerase I inhibitors or antibody-drug conjugates containing a topoisomerase inhibitor, and receipt of high-dose systemic corticosteroids within 2 weeks of cycle 1 day 1 (C2). Specific Aims: The primary objectives are safety/tolerability and magrolimab RP2D (safety run-in) and efficacy (ph2: C1, progression-free survival [PFS]; C2, objective response rate [ORR]; both by investigator). Secondary objectives include ORR, PFS, and duration of response by investigator and independent central review, overall survival, and magrolimab concentration vs time and antidrug antibodies. Present and Target Accrual: The study is enrolling in the US, Australia, and Hong Kong. Target accrual is 144 pts. Contact Information: ClinicalTrials.gov: NCT04958785.

Abstract
Coxiella burnetii is globally distributed but evidence of zoonotic transmission in the Caribbean region is scarce. The bacterium presence is suspected on the Caribbean island of St. Kitts. The risk of exposure of veterinary students was reported in other regions of the world but is not documented in the Caribbean region. The present study aimed to evaluate the risk of exposure to C. burnetii for pre-clinical veterinary students (mostly coming from the U.S.) attending an island-based veterinary school. A cross-sectional study was conducted to compare incoming and outgoing veterinary students' seroprevalence. Serology was performed using indirect immunofluorescence assay to test Coxiella burnetii Phase I and Phase II immunoglobulins M and G. Background data were gathered using a standardized questionnaire. A parallel study enrolled veterinary school employees in the same university. Of the 98 participants (48 incoming and 50 outgoing students), 41 (41.8%, 95 %CI: 31.9-52.2) were seropositive to C. burnetii. There was no significant difference between the two groups (45.8% for incoming vs. 38.0% for outgoing students) (p = 0.4). No risk factors (demographic, animal handling practices or background) were significantly more reported in the seropositive group. In the employee study, the seroprevalence was high with 8/15 seropositives (53.3%, 95 %CI: 26.6-78.7). Pre-clinical veterinary students do not have a higher risk of exposure to C. burnetii by attending the veterinary school in St. Kitts, but they are highly exposed before arrival on the island (seroprevalence of 45.8%). Most of these participants had experience with animals either through farming or previous veterinary technician employment. This indicates a high exposure in the U.S. young population aiming to become veterinarians. There is an urgent need to increase C. burnetii surveillance in animals and humans to apply relevant prevention and control measures, including recommendations for vaccination of students and professionals at risk.

Abstract
TPS1588 Background: Cancer treatment is evolving toward a more personalized approach in which the intersection of genomics, pathology and imaging methods leads to individualized care. Furthermore, identification of novel genomic alterations and other biomarkers has the potential to lead to customized, targeted treatments. Matching specific therapies to tumor biomarkers has the potential to yield valuable clinical information. Here we present a multiarm basket trial that matches patients with a broad array of metastatic solid cancers to investigational therapies alone or in combination based on specific, targetable genomic alterations or protein expression patterns that are potentially predictive of response (MyTACTIC). Historically, such trials have been conducted at large academic medical centers rather than community centers, where most US patients with cancer receive treatment. Prioritizing community centers for this study presents an exciting opportunity to generate data from a more representative patient population. Methods: This phase II, multicenter, nonrandomized, open-label study is enrolling approximately 200 participants with advanced solid tumors that harbor alterations including mutations, fusions, amplifications and protein loss in specific biomarkers that include human epidermal growth factor receptor 2 (HER2), phosphoinositide 3-kinase (PI3K), anaplastic lymphoma kinase (ALK), proto-oncogene tyrosine-protein kinase (ROS1), protein kinase B (AKT), phosphatase and tensin homolog (PTEN), high tumor mutational burden (TMB), high microsatellite instability (MSI) and deficient mismatch repair (dMMR). Patients aged ≥18 years with positive local biomarker results from tissue or blood samples will be enrolled from community oncology centers and practices. Eligibility criteria have been broadened to allow enrollment of a diverse population of patients, including those with nonmeasurable disease, HIV or viral hepatitis infections, and to allow for previous treatment with anticancer agents in the same class. Once general and arm-specific criteria are met, patients will be assigned to 1 of 10 treatment arms to receive mono- or combination therapy with targeted agents, immunotherapy and/or chemotherapy (≤25 patients per arm). The primary objective is to evaluate confirmed objective response rate, as assessed by the investigator according to RECIST version 1.1 or RANO criteria for primary central nervous system tumors. Progression-free survival, duration of response, overall survival and safety will also be assessed. Special attention has been paid to the study design and implementation to ensure equitable access, along with flexibility to add additional baskets. Enrollment is ongoing. Clinical trial information: NCT04632992.

Abstract
Cholangiocarcinoma is an aggressive malignancy with poor overall survival. Approximately 15% of intrahepatic cholangiocarcinomas contain FGFR alterations. Infigratinib is an oral FGFR 1-3 kinase inhibitor. Favorable results from a Phase II trial of infigratinib in advanced/metastatic FGFR-altered cholangiocarcinomas has led to its further investigation in the front-line setting. In this article we describe the design, objectives and rationale for PROOF 301, a Phase III multicenter, open label, randomized trial of infigratinib in comparison to standard of care gemcitabine and cisplatin in advanced/metastatic cholangiocarcinoma with FGFR2 translocations. The results of this study have the potential to define a new role for a chemotherapy-free, targeted therapy option in the front-line setting for these patients. Clinical Trial Registration: NCT03773302 (ClincalTrials.gov).

Abstract
4591 Background: Cholangiocarcinoma (CCA) is the most common biliary tract malignancy with an estimated incidence of 8,000–10,000 patients/year in the US. Chemotherapy is the most common second-line treatment with reported outcomes in patients with CCA. Response rates of < 10% and median progression-free survival (PFS) times of ~3–4 months have been reported with second-line chemotherapy regimens, including FOLFOX in the ABC-06 trial. Fibroblast growth factor receptor 2 ( FGFR2) fusions occur in 13–17% of CCA and multiple targeted agents are in development for patients with FGFR2 fusions. To date, the outcome of patients with CCA and FGFR2 fusions receiving standard second-line chemotherapy is unknown. Methods: Patients with advanced CCA and FGFR2 fusions after prior treatment with gemcitabine-based chemotherapy were enrolled in a single-arm phase 2 study (NCT02150967) and received the FGFR1–3 selective TKI infigratinib (previously BGJ398) 125 mg orally qd on d1–21, cycles repeated q28 days until unacceptable toxicity, disease progression, investigator discretion, or withdrawal of consent. A retrospective analysis of a subset of patients who received infigratinib as third- or later-line treatment was performed. Investigator-assessed PFS and best overall response (BOR, per RECIST 1.1) following second-line chemotherapy (pre-infigratinib) and third-line or later-line infigratinib were calculated. Results: Of the 71 patients (44 women; median age 53 years) with FGFR2 fusions enrolled at the time of analysis (datacut 8 August 2018), 37 (52%) were included in this retrospective analysis. Median PFS with standard second-line chemotherapy was 4.63 months (95% CI 2.69–7.16) compared with 6.77 months (95% CI 3.94–7.79) for third- and later-line infigratinib. BOR for second-line chemotherapy was 5.4% (95% CI 0.7–18.2) compared with 21.6% for third- and later-line infigratinib (95% CI 9.8–38.2). Conclusions: Outcomes from second-line chemotherapy in patients with CCA and FGFR2 fusions were similar to those reported in the literature for all patients with CCA regardless of genomic status and remain dismal. Infigratinib administered as third- and later-line treatment resulted in a meaningful PFS and ORR benefit in patients with CCA and FGFR2 fusions. Clinical trial information: NCT02150967 .

Abstract
TPS4155 Background: Cholangiocarcinoma is the most common biliary tract malignancy with approximately 5,000–10,000 new cases annually in the USA. The fibroblast growth factor receptor (FGFR) family plays an important role in cholangiocarcinoma, with FGFR2 gene fusions detected in about 15% of patients with cholangiocarcinoma. Infigratinib is an ATP-competitive, FGFR1–3-selective oral tyrosine kinase inhibitor. First-line treatment with chemotherapy offers only modest benefit and more effective treatment options are needed. Based on preliminary response data of infigratinib in relapsed/refractory cholangiocarcinoma with FGFR2 fusions/translocations (Phase 2 Study CBJG398X2204), the PROOF trial is evaluating infigratinib versus gemcitabine + cisplatin in front-line patients with advanced cholangiocarcinoma with FGFR2 gene fusions/translocations. Methods: Patients with advanced/metastatic or inoperable cholangiocarcinoma are randomized 1:1 to oral infigratinib once daily for 21 days of a 28-day treatment cycle versus IV gemcitabine (1000 mg/m2) + cisplatin (25 mg/m2) on days 1 and 8 of a 21-day cycle. Treatment will continue until confirmed progressive disease by central review, intolerance, withdrawal of informed consent, or death. After 8 cycles of gemcitabine + cisplatin, patients can continue treatment if the investigator considers that they are deriving continued benefit. Patients on the gemcitabine + cisplatin arm who progress can cross-over to infigratinib. The primary endpoint is progression-free survival (PFS, per RECIST v1.1 central review). Secondary endpoints include overall survival, PFS (investigator determined), overall response rate, disease control rate, duration of response, and safety. Quality of life, PK and exploratory genetic alterations/biomarkers will also be measured. Current status: The study was initiated in February 2019 with planned enrollment of 350 patients with confirmed FGFR2 gene fusions/translocations. Clinical trial information: NCT03773302.

Abstract
TPS9101 Background: Platinum-based chemotherapy (chemo) is the current standard of care for patients (pts) with newly diagnosed advanced non-squamous NSCLC. The combination of platinum-based chemo and pemetrexed (pem) provides comparable benefit to pts as other standard platinum doublets commonly used and has a favorable toxicity profile. However, the survival benefit conferred by this combination leaves considerable room for improvement. The anti–PD-L1 mAb atezolizumab (atezo) inhibits the interaction of PD-L1 with its receptors PD-1 and B7.1, thereby restoring tumor-specific T-cell immunity. In the OAK trial, pts with 2L/3L advanced NSCLC had improved mOS in the atezo arm (13.8 mo) vs the docetaxel arm (9.6 mo), with a survival benefit observed across PD-L1 expression levels. The potential for chemo to further augment responses to atezo, with tolerable safety, has also been demonstrated. A global, Phase III, randomized, open-label trial, IMpower132 (NCT02657434), is being conducted to evaluate 1L atezo + platinum-based chemo + pem in chemo-naive pts with stage IV NSCLC. Methods: Eligibility criteria include stage IV NSCLC, measurable disease (RECIST v1.1), no prior chemo and ECOG PS 0-1. Exclusion criteria include tumors known to harbor EGFR or ALK driver mutations, untreated CNS metastases, autoimmune disease and prior exposure to immunotherapy. Pts will be enrolled regardless of PD-L1 expression status and randomized to the treatment arms. Pts will be stratified by sex, ECOG PS, type of chemo (carboplatin [carbo] vs cisplatin [cis]) and smoking status. Pts will receive four or six 21-day cycles of either atezo + carbo/cis + pem or carbo/cis + pem. Following the induction phase, pts will receive maintenance atezo + pem or pem alone, depending on their allocated treatment regimen. Pts receiving atezo may continue until loss of clinical benefit.Co-primary endpoints are investigator-assessed PFS and OS. Secondary endpoints include IRF-assessed PFS, investigator-assessed ORR and safety. Predictive biomarkers associated with efficacy will be evaluated. Approximately 568 pts will be enrolled. Clinical trial information: NCT02657434.

Abstract
TPS8576 Background: The anti–PD-L1 mAb atezo blocks the interaction between PD-L1 and its receptors PD-1 and B7.1 and restores anti-tumor immunity. In the OAK trial, pts with 2L/3L advanced NSCLC had improved mOS in the atezo arm (13.8 mo) vs the docetaxel (doc) arm (9.6 mo), with a survival benefit observed regardless of PD-L1 expression levels on tumor cells (TC) or tumor-infiltrating immune cells (IC). However, more effective treatment options are needed for pts with early-stage NSCLC. A global Phase III, randomized, open-label trial, IMpower010 (NCT02486718), is being conducted to evaluate the efficacy and safety of atezo vs BSC following adjuvant cisplatin (cis)–based chemotherapy (chemo) in pts with resected stage IB (tumors ≥ 4 cm)-IIIA NSCLC. Methods: Pts eligible for study must have complete tumor resection 4 to 12 weeks prior to enrollment for pathologic stage IB (tumors ≥ 4 cm)-IIIA NSCLC, be adequately recovered from surgery, be able to receive cis-based adjuvant chemo and have an ECOG PS 0-1. Pts with other malignancies, autoimmune disease, hormonal cancer or radiation therapy within 5 years and prior chemo or immunotherapy are excluded from study. Approximately 1127 pts will be enrolled regardless of PD-L1 status. Pts will receive up to four 21-d cycles of cis-based chemo (cis [75 mg/m2 IV, d 1] + vinorelbine [30 mg/m2 IV, d 1, 8], doc [75 mg/m2 IV, d 1] or gemcitabine [1250 mg/m2 IV, d 1, 8], or pemetrexed [500 mg/m2 IV, d 1; only non-squamous NSCLC]). No adjuvant radiation therapy is permitted. After adjuvant chemo, eligible pts will be randomized 1:1 to receive 16 cycles of atezo 1200 mg q3w or BSC. Stratification factors include sex, histology (squamous vs non-squamous), disease stage (IB vs II vs IIA) and PD-L1 status by IHC (TC2/3 [≥ 5% expressing PD-L1] and any IC vs TC0/1 [ < 5%] and IC2/3 vs TC0/1 and IC0/1 [ < 5%]). The primary endpoint is disease-free survival; secondary endpoints include OS and safety. Exploratory biomarkers, including PD-L1 expression, immune- and tumor-related biomarkers before, during and after treatment with atezo and at radiographic disease recurrence, or confirmation of new primary NSCLC, will be evaluated. Clinical trial information: NCT02486718.

Abstract
A nanopatternable polydimethylsiloxane (PDMS) oligomer layer is demonstrated as an interfacial adhesive for its intrinsic transferability and universal adhesiveness. Utilizing the well-established surface modification and bonding techniques of PDMS surfaces, irreversible bonding is formed (up to 400 kPa) between a wide range of substrate pairs, representing ones within and across different materials categories, including metals, ceramics, thermoset, and thermoplastic polymers.

Abstract
Optical measurements of the refractive state of the eyes of various shark species typically have depicted sharks as hyperopic (far-sighted) with little evidence of accommodation (i.e. the ability to change focus for visualizing objects at different distances from the eye). In this study, we used infrared video retinoscopy to measure the refractive state in juvenile lemon sharks (Negaprion brevirostris). This technique allows dynamic measurement of refractive state in free-swimming animals as they pass by an aquarium window. We found that unrestrained lemon sharks are focused emmetropically relative to a 1-m distant photorefractor for the lateral visual field. However, when restrained either right side up or upside down (the latter inducing tonic immobility), the sharks become increasingly hyperopic, an artifact also reported in some other vertebrates. In addition, unrestrained lemon sharks display small amplitude accommodative excursions. Thus, refractive state measurements on restrained sharks in general may not reflect the natural, resting state of the shark eye, but rather, an induced hyperopia and lack of accommodative function. Such an artifact may be present in other vertebrate species, underscoring the need to obtain measurements of refractive state in unrestrained animals.

Abstract
We employed neutralizing infrared videophotorefraction and photokeratometry to examine the manifest refractions and corneal curvatures of 21 species of anurans (frogs and toads) in five families (Dendrobatidae, Bufonidae, Centrolenidae, Leptodactylidae, and Hylidae) resident in Central America. We found that all of the anurans exhibited hyperopic refractions in air, but that the observed hyperopia was not totally explained by the small eye artefact (Glickstein & Millodot, 1970). An allometric comparison of the corneal radii of these small anurans with those of a large number of other vertebrates, inferred from ocular axial lengths, showed that their corneal radii increased significantly more rapidly with increasing body size than that of other vertebrates generally (allometric slope constants: anurans: 0.270 +/- 0.032; other vertebrates: 0.151 +/- 0.004). Among the anurans examined, nocturnal Hylids had significantly larger eyes than diurnal Dendrobatid frogs and Bufonid toads.

Abstract
The presence of lower-field myopia (described in chickens, pigeons, quail and amphibians) allows these animals to keep the ground in focus while performing other visual tasks. A relationship has also been reported between the eye height and the degree of myopia observed. All of the animals reported in the literature to date are ground-foraging species. Using infrared neutralizing video retinoscopy and static photoretinoscopy we found a lower-field myopia to be absent in the barn owl (Tyto alba), Swainson's hawk (Buteo swainsonii), Cooper's hawk (Accipiter cooperi) and American kestrel (Falco sparverius). These findings suggest that the presence or absence of a lower-field myopia is a function of the visual ecology of the animal.

Abstract
Brown kiwis are an endangered species of nocturnal, flightless birds which are native to New Zealand. The resting focus of two specimens has previously been studied by retinoscopy in a zoo while the birds were restrained by their keeper (Sivak and Howland 1987). Those birds appeared to be hyperopic (farsighted) by 2-7 D. In this study, examination with infrared photorefraction of the focusing of two unrestrained, feeding birds showed that they could focus objects at infinity and objects in their immediate environment and that they had modest powers of accommodation. Measurements on two 6 month old kiwi chicks showed their corneal radius of curvature to be between 2.90 and 3.00 mm (117 D and 101 D in power).

Abstract
A simple pointspread retinoscope and method of retinoscopy are described which use optical principles similar to those of photoretinoscopy or static photographic skiascopy. In this instrument the degree of defocus of an eye is estimated from the disappearance of the bright fundal reflex or "crescent" in the eye of the subject when the distance between the light source and the eye of the observer is increased systematically. The instrument is particularly suitable for large scale screening efforts because it is easy to use and can be constructed from inexpensive materials. The pointspread retinoscope was calibrated against an artificial eye of known defocus. Additionally, results from pointspread retinoscopy were compared against meridional photorefractive data from a sample of infants and young children, and a significant correlation was found to exist between measurements made by the two methods.
