A SMART decade: outcomes of an integrated, inclusive, first-year college-level STEM curricular innovation

In the early 2000s, our primarily undergraduate, white institution (PUI/PWI), began recruiting and enrolling higher numbers of students of color and first-generation college students. However, like many of our peer institutions, our established pedagogies and mindsets did not provide these students an educational experience to enable them to persist and thrive in STEM. Realizing the need to systematically address our lack of inclusivity in science majors, in 2012 faculty from multiple disciplines developed the Science, Math, and Research Training (SMART) program. Here, we describe an educational innovation, originally funded by a grant from the Howard Hughes Medical Institute, designed to support and retain students of color, first generation college students, and other students with marginalized identities in the sciences through a cohort-based, integrated, and inclusive first-year experience focused on community and sense of belonging. The SMART program engages first-year students with semester-long themed courses around “real world” problems of antibiotic resistance and viral infections while integrating the fields of Biology, Chemistry, Mathematics, and an optional Computer Science component. In the decade since its inception, 97% of SMART students have graduated or are on track to graduate, with 80.9% of these students earning a major in a STEM discipline. Here, we present additional student outcomes since the initiation of this program, results of the student self-evaluative surveys SALG and CURE, and lessons we have learned from a decade of this educational experience

Development of anti-CD32b antibodies with enhanced Fc function for the treatment of B and plasma cell malignancies

The sole inhibitory Fcγ receptor CD32b (FcγR2b) is expressed throughout B and plasma cell development and on their malignant counterparts with the highest expression found on multiple myeloma. Additionally, CD32b expression on tumor cells is known to sequester IgG Fc whereby providing a mechanism of resistance to therapeutic monoclonal antibodies (mAb) with Fc dependent activity. Taken together, CD32b represents an attractive tumor antigen for targeting with a mAb. To this end, two anti-CD32b mAbs, NVS32b1 and NVS32b2, were developed. The complementarity-determining regions (CDRs) of these antibodies bind the CD32b Fc binding domain with high specificity and affinity while the Fc region is afucosylated to enhance activation of FcR on immune effector cells. NVS32b mAbs selectively depletes CD32b+ healthy and malignant B cells but spares myeloid cells and CD32a+ cells. These antibodies mediate potent killing of opsonized cells via antibody dependent cellular cytotoxicity and phagocytosis (ADCC & ADCP), as well as complement dependent cytotoxicity (CDC). Additionally, NVS32b CDRs block the CD32b Fc binding domain, thereby minimizing CD32b mediated resistance to therapeutic mAbs with Fc dependent activity, including rituximab, obinutuzumab, and daratumumab. NVS32b mAbs demonstrate robust antitumor activity against CD32b positive xenografts in vivo and immunomodulatory activity including recruitment of macrophages to the tumor microenvironment and enhancement of DC maturation in response to immune-complexes. The activity of NVS32b mAbs on CD32b+ primary malignant B and plasma cells was confirmed on samples from CLL and MM patients. NVS32b mAbs demonstrated great therapeutic potential, as a single agent or in combination with other mAb therapeutics

Development of anti-CD32b antibodies with enhanced Fc function for the treatment of B and plasma cell malignancies

The sole inhibitory Fcg receptor CD32b (Fcg RIIb) is expressed throughout B and plasma cell development and on their malignant counterparts. CD32b expression on malignant B cells is known to provide a mechanism of resistance to rituximab that can be ameliorated with a CD32b-blocking antibody. CD32b, therefore, represents an attractive tumor antigen for targeting with a monoclonal antibody (mAb). To this end, two anti-CD32b mAbs, NVS32b1 and NVS32b2, were developed. Their complementarity-determining regions (CDR) bind the CD32b Fc binding domain with high specificity and affinity while the Fc region is afucosylated to enhance activation of Fcg RIIIa on immune effector cells. The NVS32b mAbs selectively target CD32bþ malignant cells and healthy B cells but not myeloid cells. They mediate potent killing of opsonized CD32bþ cells via antibody-dependent cellular cytotoxicity and phagocytosis (ADCC and ADCP) as well as complement-dependent cytotoxicity (CDC). In addition, NVS32b CDRs block the CD32b Fc–binding domain, thereby minimizing CD32b-mediated resistance to therapeutic mAbs including rituximab, obinutuzumab, and daratumumab. NVS32b mAbs demonstrate robust antitumor activity against CD32bþ xenografts in vivo and immunomodulatory activity including recruitment of macrophages to the tumor and enhancement of dendritic cell maturation in response to immune complexes. Finally, the activity of NVS32b mAbs on CD32bþ primary malignant B and plasma cells was confirmed using samples from patients with B-cell chronic lymphocytic leukemia (CLL) and multiple myeloma. The findings indicate the promising potential of NVS32b mAbs as a single agent or in combination with other mAb therapeutics for patients with CD32bþ malignant cells
