Book Review - American Higher Education: A History
No full textAmerican Higher Education: A History, by Christopher J. Lucas is a historical narrative of the origins and development of the system of higher learning in place in contemporary America. It extends and updates earlier works in this area, and provides, as the author had hoped, "a more 'accessible' historical account, useful chiefly for nonspecialists and a more general readership . . ." but is nonetheless a thorough review of the historical underpinnings of American higher education. This work is recommended for students and professionals who seek a broad understanding of contemporary higher education and how it came to pass

SEA-BCMA, an Investigational Nonfucosylated Monoclonal Antibody: Ongoing Results of a Phase 1 Study in Patients with Relapsed/Refractory Multiple Myeloma (SGNBCMA-001)
No full textAbstract
Background
Patients (pts) with relapsed/triple-class refractory (R/R; refractory to a proteasome inhibitor, immunomodulatory drug or anti-CD38 antibody) multiple myeloma (MM) have limited treatment options. A need remains for novel combination therapies with manageable toxicity and non-cross-resistant mechanisms of action. B-cell maturation antigen (BCMA) is expressed in most MM pt tumors. SEA-BCMA is an investigational, humanized, nonfucosylated IgG1 monoclonal anti-BCMA antibody. Proposed mechanisms of action of SEA-BCMA include blocking of BCMA-mediated pro-survival and proliferative signaling, mediating antibody-dependent cellular phagocytosis, and displaying enhanced antibody-dependent cellular cytotoxicity. Preclinical data demonstrate promising antitumor activity and versatile combinability. Here, we present preliminary data from the first-in-human Phase 1 clinical trial.
Methods
SGNBCMA-001 (NCT03582033) is an ongoing phase 1, open-label, multicenter, dose-escalation and expansion study to evaluate the safety, tolerability and antitumor activity of SEA-BCMA in adults with R/R MM not previously exposed to any other BCMA-directed therapy. Part A tested monotherapy safety and tolerability with dose escalation (100-1600 mg flat dosing once every 2 weeks [Q2W] by intravenous infusion), and dose expansion at the highest tolerated dose. Parts B and C aim to optimize efficacy by testing intensified dosing (Part B; weekly [Q1W] induction dosing of SEA BCMA for 8 weeks is followed by Q2W maintenance dosing) and dexamethasone (DEX) combination therapy (Part C) in pts who have received ≥3 prior lines of therapy for MM and are triple-class refractory. Responses are assessed per the 2016 International Myeloma Working Group criteria.
Results
As of June 15, 2021, Part A completed enrollment. A total of 55 pts received SEA-BCMA (see Table 1 for pt characteristics).
SEA-BCMA was generally well tolerated, and the maximum tolerated dose was not reached in the 5 dose levels tested in Part A (100, 200, 400, 800, or 1600 mg Q2W; n=2, 2, 2, 7, and 7, respectively). At 800 mg, 1 of 7 pts reported a Grade 3 infusion-related reaction (IRR), which met dose-limiting toxicity (DLT) criteria by lasting >24 hours despite supportive care. This constituted the single DLT observed during dose escalation. Subsequently, dose expansion (n=15) proceeded at 1600 mg Q2W. The most common treatment-emergent adverse events (TEAEs) observed with 1600 mg Q2W (n=22) were fatigue (32%), pyrexia (23%), IRR (23%), and hypertension (23%) for non-hematological events, and anemia (14%) for hematologic events. The most common ≥Grade 3 TEAEs with 1600 mg Q2W were anemia and syncope (9% each). Following a safety monitoring review, premedication with acetaminophen + antihistamine was introduced to mitigate IRRs in expansion cohorts. Parts B and C completed parallel safety run-ins (n=6 each) at the 1600 mg dose with no DLTs observed and with similar tolerability.
Pharmacokinetic (PK) analyses indicate serum SEA-BCMA exposures increased proportionally with increasing dose with a half-life of approximately 10 days. Preliminary analyses suggest the PK profile of SEA-BCMA in combination therapy with DEX (n=5) is comparable to monotherapy and is unaltered with a change in schedule from Q2W to Q1W.
Three of 22 pts who received 1600 mg SEA-BCMA Q2W monotherapy (Part A) achieved a confirmed objective response (OR; OR rate: 14% [95% confidence interval: 2.91, 34.91]; 2 partial responses [PR], 1 very good PR [VGPR]). To date, 3 pts remain on treatment (2 PRs and 1 stable disease). The median duration of treatment was 12 weeks (Figure 1; range 4-88).
In Parts B and C, 2 of 8 (2 PR) and 2 of 12 (1 VGPR, 1 PR) pts reported a confirmed OR; 3 of the 4 responding pts remain on treatment in cycle 7, 8, and 9, respectively.
Conclusions
Preliminary results for SGNBCMA-001 suggest a favorable safety profile and combination potential. SEA-BCMA also showed encouraging duration on treatment and initial antitumor activity in a heavily pre-treated late-line R/R MM pt population. Expansion cohorts testing intensified SEA-BCMA dosing and the addition of DEX are underway to further assess the safety, tolerability, and estimate of SEA-BCMA activity in the context of these treatment approaches. An additional expansion cohort (Part D), testing the combination of SEA-BCMA with pomalidomide and DEX in pts who have received ≥2 prior lines of therapy, is now enrolling.

A phase 1b study evaluating the safety and preliminary efficacy of berzosertib in combination with gemcitabine in patients with advanced non-small cell lung cancer
No full text\ua9 2021 The Author(s). Objectives: Berzosertib (formerly M6620, VX-970) is an intravenous, highly potent and selective, first-in-class ataxia telangiectasia and Rad3-related (ATR) protein kinase inhibitor. We assessed the safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of berzosertib plus gemcitabine in an expansion cohort of patients with advanced non-small cell lung cancer (NSCLC). The association of efficacy with TP53 status and other tumor markers was also explored. Materials and methods: Adult patients with advanced histologically confirmed NSCLC received berzosertib 210 mg/m2 (days 2 and 9) and gemcitabine 1000 mg/m2 (days 1 and 8) at the recommended phase 2 dose established in the dose escalation part of the study. Results: Thirty-eight patients received at least one dose of study treatment. The most common treatment-emergent adverse events were fatigue (55.3%), anemia (52.6%), and nausea (39.5%). Gemcitabine had no apparent effect on the PK of berzosertib. The objective response rate (ORR) was 10.5% (4/38, 90% confidence interval [CI]: 3.7–22.5%). In the exploratory analysis, the ORR was 30.0% (3/10, 90% CI: 9.0–61.0%) in patients with high loss of heterozygosity (LOH) and 11.0% (1/9, 90% CI: 1.0–43.0%) in patients with low LOH. The ORR was 33.0% (2/6, 90% CI: 6.0–73.0%) in patients with high tumor mutational burden (TMB), 12.5% (2/16, 90% CI: 2.0–34.0%) in patients with intermediate TMB, and 0% (0/3, 90% CI: 0.0–53.6%) in patients with low TMB. Conclusions: Berzosertib plus gemcitabine was well tolerated in patients with advanced, pre-treated NSCLC. Based on the observed clinical efficacy, future clinical trials should involve genomically selected patients
