Abstract Introduction Approximately 40% of patients with DLBCL will experience relapse after initial treatment with standard-of-care chemo-immunotherapy. Effective treatment options are limited for patients who experience first-line treatment failure, particularly for those with R/R disease following CAR T-cell therapy or those not able to receive CAR T-cell therapy (Sehn et al, N Engl J Med. 2021). GOLCA is a potential, first-in-class, oral CELMoD agent designed for the treatment of lymphoma, with preferential distribution to lymphoid organs and enhanced activity in lymphoma cell lines. GOLCA drives the closed, active conformation of cereblon to induce rapid and deep degradation of Ikaros and Aiolos, leading to direct cell killing (agnostic of cell of origin) and immunomodulatory activity. In the two-part, multicenter, first-in-human Phase 1/2 study (CC-99282-NHL-001; NCT03930953), GOLCA was well tolerated and effective in patients with R/R DLBCL (Bachy et al, ICML 2025, #148). Here, we provide longer follow-up in patients with R/R DLBCL from Part B of the study. Methods Patients with R/R DLBCL and disease progression after ≥ 2 lines of therapy or transplant-ineligible patients after ≥ 1 line of therapy were included in the study. Patients received GOLCA monotherapy orally, once daily at different dosing schedules in Part A. In Part B, GOLCA was dosed at 0.2 or 0.4 mg (14 days on/14 days off) ± R. Total GOLCA treatment duration was up to 2 years or until progressive disease (PD)/unacceptable toxicity. Primary objectives included safety and recommended Phase 2 dose determination. Results As of April 3, 2025, a total of 77 patients with R/R DLBCL were enrolled in Part B Cohort C (GOLCA 0.2 mg + R, n = 39; GOLCA 0.4 mg + R, n = 38). Median age was 66 years (range, 20–86). Patients were heavily pre-treated; median number of prior treatments was 4 (range, 1–11), 55% of pts had prior CAR T-cell therapy, 38% had prior bispecific antibody treatment, and 44% were refractory to last treatment. Ten patients (13%) were ongoing, 4 completed 2 y of treatment, and 63 (82%) had discontinued treatment, mostly due to PD (n = 48 [62%]). The most common any-grade (G) treatment-emergent adverse events (AEs) in the 0.2- and 0.4-mg cohorts, respectively, were neutropenia (54% and 84%), an on-target side effect of GOLCA, and anemia (44% and 45%). G3/4 neutropenia was reported in 49% of patients with 0.2 mg and 79% with 0.4 mg, and febrile neutropenia (FN) in 5% and 16%, respectively. Granulocyte colony-stimulating factor was used in 81% and 88% of patients with neutropenia and 50% and 100% of patients with FN in the 0.2-mg and 0.4-mg cohorts. Dose interruptions (mainly due to infections/neutropenia) occurred in 49% and 53% of patients and discontinuations due to AEs occurred in 10% and 3% with 0.2 and 0.4 mg. One G5 pneumonia was considered related to study treatment (0.2 mg). The median follow-up was 11.8 months (range, 3.1–35.1) with 0.2 mg and 16.2 months (range, 3.8–31.4) with 0.4 mg. The overall response rate (ORR) in efficacy evaluable patients was 34% (complete response rate [CRR], 20%) with 0.2 mg (n = 35) and 58% with 0.4 mg (n = 36), including a CRR of 44% with this dose. In patients with prior T-cell–redirecting treatment, the ORR was 33% (CRR, 22%) with 0.2 mg (n = 18) and 56% (CRR, 38%) with 0.4 mg (n = 16). Seven of 35 (0.2 mg) and 14 of 36 (0.4 mg) patients experienced durable response > 12 months. The median time to response with both 0.2 and 0.4 mg was 1.8 months. In patients with durable responses (remained in response [CR or partial response] for more than two consecutive efficacy assessments) to GOLCA, circulating tumor DNA reduction from baseline continues to deepen over time. Response was similar across clones/tumor variants. Conclusions With additional follow-up, GOLCA + R continued to demonstrate a predictable and manageable safety profile, with no new safety signals observed at longer follow-up. Durable responses were shown in heavily pretreated patients with R/R DLBCL, including those with prior T-cell–redirecting therapy. GOLCA + R induced a decrease in circulating tumor DNA across tumor variants. These data support the ongoing development of GOLCA + R in patients with R/R non-Hodgkin lymphoma.

Abstract Introduction The monoclonal gammopathies of renal significance (MGRS) are defined by the presence of a nephrotoxic monoclonal protein in the absence of a well-defined malignant entity. Mechanistically it has been postulated that, across the varied subtypes of MGRS, abnormal plasma cell or B-cell clones in the marrow produce nephrotoxic proteins; however, in many cases, no paraprotein is detected by conventional laboratory methods and the bone marrow can be morphologically normal. The genomic underpinnings of MGRS are unexplored and, due to the rarity of this disease, clinicians are often left to unable to determine the exact nature of the clonal cell populations. We carried out a pilot study to characterize ctDNA in MGRS patients (pts). The first phase of the protocol sought to collect peripheral blood samples and, when possible, matched bone marrow aspirates, from MGRS pts to evaluate the feasibility of ultra-low pass whole genome sequencing (ULP-WGS) from peripheral blood to identify and characterize ctDNA. Methods We report ULP-WGS results from peripheral blood samples in the initial phase of the study. Peripheral blood samples were collected from renal biopsy proven non-amyloidosis MGRS pts prior to the initiation of treatment. Cell free DNA (cfDNA) was extracted and quantified. A total of 5-20 ng of cfDNA input was used for ULP-WGS. Libraries were pooled and sequenced using 100-bp paired-end runs to an average genome-wide coverage of 0.5x. After deconvolution and alignment, fragments with size 90-150bp were extracted using samtools. IchorCNA was utilized to calculate tumor fraction based on a panel of normals derived from three plasma samples from healthy controls. Model parameters were optimized for low tumor fraction and a threshold of 3% ctDNA was used to identify positive samples. Renal responses were assessed based on International Kidney and Monoclonal Gammopathy (IKMG) group criteria. Results Nine pts and were consented and gave samples for the study along with 3 healthy controls. Seven pts were sequenced, 4 of which were females and 3 were males. Median age was 58 years. Among sequenced pts, 5 presented with proliferative glomerulonephritis with monoclonal immune deposition (PGNMID) and 2 with light chain deposition disease (LCDD). Both patients with LCDD were kappa predominant and showed detectable plasma clones (8% and 3%). One of these pts displayed t(11:14) on bone marrow FISH testing. Among the 5 pts with PGNMID, 3 had IgG kappa deposition and only one had a detectable plasma clone (5%), which harbored trisomy 9 by FISH. Bone marrow flow cytometry was positive in 2 pts. Median 24-hour urine protein content was 7.11g (0.92 – 10.58), median serum albumin 3.20 g/dL (2.90 – 4.90) and median serum creatinine at the time of diagnosis was 2.15 mg/dL (1.30-6.40). CKD was present in 6 of 7 pts at the time of diagnosis. Four pts had known hypertension. One exhibited a history of malignancy and one had a history of autoimmune disease. ctDNA was detectable at a threshold of > 3.0% of cfDNA in 5 of 7 pts. Median ctDNA content was 4.0% (3.18% - 14.97%) of cfDNA. Four of the 5 samples containing ctDNA were hyperdiploid. Chromosome 19 was the most common site of copy number increase whereas chromosomes 6, 10, and 18 exhibited the most frequent decreases in copy number. Two pts with PGNMID had detectable ctDNA without evidence of a serological or marrow-based clone. All pts received daratumumab, cyclophosphamide, bortezomib and dexamethasone as initial treatment. Five pts responded to therapy. Two patients ultimately underwent autologous stem cell transplant and a single patient received venetoclax as second line therapy. Of the patients exhibiting detectable ctDNA, three did not exhibit renal response to initial treatment. Both pts without ctDNA had PGNMID and responded to frontline treatment. Mass spectrometry analysis and deep targeted sequencing of bone marrow aspirates and peripheral blood will be presented. Conclusions To our knowledge, this is the first study to detect ctDNA in MGRS. ULP-WGS, when combined with targeted sequencing and diagnostic modalities such as mass spectrometry, has the potential to not only to aid in diagnosis and treatment selection on a practical basis, but also to begin to unravel the underlying genomics of this rare disease. This approach has potential to serve as a platform for further genomic exploration and biomarker development in MGRS.

ABSTRACT The American College of Clinical Pharmacy (ACCP) first described the role and history of the pharmacist as principal investigator (PI) in 2000. An update was published in 2010, citing evidence from NIH and the ClinicalTrials.gov registry that showed an increase in the number of individuals with a Pharm.D. degree engaging in pharmacist‐directed research. The 2025 ACCP Publications Committee was charged with providing an update to the 2010 paper. Key findings include a substantial increase in the total amount of federal funding awarded to schools of pharmacy (SoP) between 2011 and 2023, a modest increase in the number of pharmacists receiving federal grants when comparing 2010 with 2024, and evidence of pharmacist leadership and engagement in Clinical and Translational Science Award networks and service on national grant review panels. It remains challenging, however, to ascertain accurate and reliable data on pharmacists serving in PI roles because of the limitations of currently available data sources. This is especially true for pharmacist PIs who receive non‐federal funding. Future opportunities include a continued emphasis on training programs to prepare pharmacists for PI roles, greater institutional support (e.g., research infrastructure, mentoring programs) for pharmacists serving in PI roles, better promotion of research career tracks to Pharm.D. students and trainees, enhanced efforts at SoP to pursue institutional training grants, and more collaborative efforts across professional organizations to advocate for pharmacist‐scientists. An urgent call to action is necessary to ensure the future growth and success of pharmacist‐directed research.

Objective Ambient listening with subsequent artificial intelligence enabled medical record documentation is changing how physicians interact with the electronic health record (EHR). We studied primary care physician use, documentation time, and changes in note metrics associated with ambient listening technology. Methods We calculated the percentage of physicians adopting the ambient listening tool, Abridge. Note input contributed by Abridge was determined by the percentage of total characters in generated notes. Using the Epic EHR Signal metrics, we analyzed the change in note documentation time and note length for Abridge users before and after they implemented Abridge in their note generation process. Results The percentage of physicians using Abridge increased from 15% to 50% in 8 weeks. Adoption was also reflected in the percentage of the note attributable to the use of ambient listening technology. Note content generated by Abridge tripled, from 5% to 15% over the same 8 weeks. After Abridge adoption, 332 primary care physicians had a mean time of 4.16 minutes [confidence interval (CI) 95%; 3.86, 4.46] time in notes per note in a paired comparison to 5.11 minutes [CI 95%; 4.75, 5.47] per note prior to Abridge. Mean time saved per note after Abridge was 0.95 minutes [CI 95%; 0.48, 1.42, p < 0.0001], an 18.6% reduction in time. Mean note length for Abridge adopters increased by 238 characters [CI 95%; 89, 387, p < 0.0001] from a pre-implementation mean of 4404 characters per note (+5.4%). Conclusion Ambient listening had rapid uptake and widespread use by physicians in primary care. It was also associated with a significant decrease in time in notes.

PURPOSE The difference in time to serum calcium normalization and rates of subsequent refractory hypocalcemia between bisphosphonates requires further investigation. Our primary objective was to assess the difference in normalization of serum calcium between pamidronate and zoledronic acid during treatment of hypercalcemia of malignancy (HCM) and rates of subsequent, refractory hypocalcemia following therapy. METHODS A retrospective review of patients with cancer who received pamidronate or zoledronic acid inpatient at Mayo Clinic for treatment of HCM between January 2018 and January 2024 was conducted. Logistic regression evaluated the association between treatment groups and outcomes. Multivariable modeling was adjusted for baseline differences, including severity of hypercalcemia. RESULTS We evaluated 856 patients. The median age was 68 (IQR, 59-75) years, and 476 (55.6%) were male. The most common cancer diagnoses were lymphoma (n = 158, 18.5%), followed by multiple myeloma (n = 145, 16.9%) and lung cancer (n = 111, 13%). Overall, 292 (46.8%) patients and 154 (32.8%) patients achieved serum calcium normalization by hospital day 4 and day 7, respectively. The rate of normalization was similar between all bisphosphonates, regardless of pamidronate dose. Significantly higher rates of hypocalcemia were observed on day 4 for patients who received zoledronic acid 4 mg once compared with either dose (60 mg once and 90 mg once) of pamidronate (40.7% v 27.6% v 26.8%, P = .049, respectively). No significant difference in rates of hypocalcemia were observed on day 7 (56.8% v 50% v 42.9%, P = .26, respectively) and day 30 (39.1% v 39.0% v 37.5%, P = .50, respectively). CONCLUSION Bisphosphonates were equally efficacious in normalizing serum calcium in patients with HCM. Pamidronate 90 mg was not more efficacious than 60 mg. Rates of refractory hypocalcemia were similar.

PURPOSE Neoadjuvant immune checkpoint inhibitors (nICIs) have demonstrated high response rates in deficient mismatch repair/microsatellite instability–high (dMMR/MSI-H) gastroesophageal adenocarcinoma (GEA). The NEONIPIGA and INFINITY trials demonstrated high rates of pathologic complete response (pCR) in this patient population. Furthermore, the INFINITY trial explored the feasibility of managing these patients nonoperatively, demonstrating promising results. This study aimed to evaluate clinical outcomes of nICIs in resectable dMMR/MSI-H GEA, with a focus on the feasibility of nonoperative management (NOM). MATERIALS AND METHODS This retrospective cohort study included patients with resectable dMMR/MSI-H GEA and treated with nICIs ± surgery at the Mayo Clinic. Patients were identified from institutional records, and clinical data were retrospectively reviewed. Primary outcomes were clinical complete response (cCR) and pCR. Secondary outcomes included event-free survival (EFS), radiologic complete response (rCR), and immune-related adverse events (irAEs). RESULTS A total of 26 patients treated between April 1, 2017, and July 30, 2025, were identified. Nine patients (34.6%) underwent surgery, of whom six (66.7%) achieved pCR. Seventeen patients (65.4%) pursued NOM, with 10 (71.4%) of 14 evaluable patients achieving cCR and 14 (82.4%) of 17 evaluable achieving rCR. One patient who initially achieved cCR had a local recurrence on surveillance endoscopy and underwent salvage endoscopic resection. At a median follow-up of 19.3 months, 15 (88.2%) of 17 patients in the NOM cohort were alive and metastasis-free, with EFS rates of 87.3% at 12 and 24 months for all patients. irAEs occurred in nine patients (34.6%), with no grade ≥3 toxicities. CONCLUSION In this retrospective cohort study, nICIs led to high cCR and pCR rates in resectable dMMR/MSI-H GEA, supporting the use of immune checkpoint inhibitors in this setting and the feasibility of NOM in select patients.
