WILMINGTON, Del., Feb. 25, 2025 /PRNewswire/ -- D2 Capital Advisors arranged $26,000,000 in permanent financing for a recently completed lab and R&D building in Wilmington's Chestnut Run Innovation & Science Park (CRISP). The 80,0000 square foot state-of-the-art life sciences project was developed by MRA Group, a leading developer of life science campuses. The permanent financing was arranged by Philadelphia-based D2 Capital Advisors' Jack Cortese, David Frankel, and John Lightcap. Continue Reading Photo courtesy of MRA Group. The new life sciences building was completed in December 2023 and is fully occupied by Prelude Therapeutics on a long-term lease. Prelude Therapeutics is a clinical-stage precision oncology company developing innovative drug candidates targeting critical cancer cell pathways. MRA Group, a recognized leader in the creation of incubator, production, and research & development laboratories acquired the campus from DuPont in November 2021 and began a phased redevelopment of CRISP into an ecosystem for innovative companies to grow. The campus will eventually total over 1.3 million square feet of lab, R&D, and advanced manufacturing. MRA Group has already repositioned CRISP into the First State's premier center for scientific innovation and advanced production. "D2's life sciences financing experience and strong lender relationships were extremely valuable to us throughout the financing process," said Phil Butler, Executive Vice President & Partner of MRA Group. "This financing was an important milestone in our redevelopment plan for CRISP, which affords us increased financial flexibility and demonstrates a broader confidence in the region by the capital markets." "It's easy to see why Prelude chose the CRISP Campus and MRA as developer to deliver this highly functional and aesthetically pleasing wet and dry lab building" said Jack Cortese, Vice President of D2 Capital Advisors. "Still, most lenders are not aware of the positive attributes that Wilmington, DE has to offer to the life sciences community, so we spent a lot of time educating them on the sub-market, the tenant, and the surrounding tenancy." CRISP sits along the I-95 corridor and is less than 40-minutes from Philadelphia. The Philadelphia-MSA has a flourishing life sciences industry due to the area's wealth of talent, proximity to world-class research institutions and healthcare systems, and access to funding.

• PRT2527 demonstrated activity across a range of relapsed/refractory lymphoid malignancies, including patients who received prior CAR-T therapy • Prelude plans to seek a partner for future development of PRT2527 in hematologic malignancies WILMINGTON, Del., Dec. 11, 2024 (GLOBE NEWSWIRE) -- Prelude Therapeutics Incorporated (Nasdaq: PRLD) (“Prelude” or the “Company”), a clinical-stage precision oncology company, today announced the presentation of the first interim clinical data from its ongoing open-label, dose-escalation trial of PRT2527, a potent and highly selective CDK9 inhibitor, as monotherapy and in combination with zanubrutinib in patients with relapsed/refractory lymphoid malignancies. The data were presented at a poster session of the 66th American Society of Hematology Annual Meeting in San Diego, California. The study investigators reported on the 46 patients that were enrolled, treated, and safety evaluable as of September 17, 2024. PRT2527 was generally well-tolerated through 4 dosing cohorts as monotherapy and 3 dosing cohorts in combination with zanubrutinib. PRT2527 monotherapy and in combination with zanubrutinib demonstrated an acceptable safety profile with evidence of preliminary activity in patients with relapsed/refractory lymphoid malignancies, including patients who received prior CAR-T therapy. “CDK9 has long been considered a potential therapeutic approach for treating hematologic malignancies and a highly selective CDK9 inhibitor was sought to minimize off target toxicity,” stated Jane Huang, M.D., President and Chief Medical Officer of Prelude. “We are encouraged by the results demonstrated to date by PRT2527 both as a monotherapy and particularly in combination with zanubrutinib resulting in an overall response rate of 38.5% including two patients with aggressive lymphomas who had received prior CAR-T therapy. These results represent a positive step for CDK9 inhibition as a possible future therapeutic approach for patients with aggressive hematologic cancers with limited treatment options.” PRT2527 Interim Phase 1 ResultsPRT2527 is an investigational, potent and highly selective CDK9 inhibitor being evaluated in select relapsed/refractory (R/R) hematologic malignancies as monotherapy and in combination with zanubrutinib. As of the cutoff date, 46 patients with relapsed/refractory lymphoid malignancies were treated with PRT2527. 29 patients were treated once weekly via intravenous infusion at four dose levels of PRT2527 monotherapy (9 mg/m2, 15 mg/m2, 18 mg/m2, 24 mg/m2) and 17 patients were treated once weekly at three dose levels of PRT2527 (9 mg/m2, 15 mg/m2, 18 mg/m2) in combination with zanubrutinib administered orally starting on C1D1 at 320 mg daily or 160 mg BID. Initial Safety DataThe most frequent treatment emergent adverse events (TEAEs) observed in ≥20% of patients were neutropenia (48%) and nausea (33%), and the most frequent grade ≥3 TEAEs (≥10% of patients) were neutropenia (46%) and anemia (11%). Five patients discontinued treatment due to TEAEs in the monotherapy cohort; 3 TEAEs in 1 patient were treatment related: grade 3 hypotension, grade 3 diarrhea, and grade 4 neutropenia (n=1 each). No TEAEs led to treatment discontinuation in the combination therapy cohort. PRT2527 dose interruptions due to TEAEs occurred in 17 patients (11 monotherapy; 6 combination therapy). Most dose interruptions were due to neutropenia and were managed with growth factor support. One DLT of grade 3 tumor lysis syndrome (TLS) occurred in a patient with primary cutaneous peripheral T cell lymphoma who had extensive disease at the 24 mg/m2 monotherapy dose level and did not receive ramp-up dosing. TLS was managed with rasburicase and IV fluids and resolved. The patient was able to resume study treatment as planned. No DLTs were observed in the combination therapy cohort. Dose level 3 (18 mg/m2) was selected for dose confirmation for monotherapy and in combination with zanubrutinib due to higher rates of grade 3/4 neutropenia and of dose interruptions and reductions in the 24 mg/m2 dose level. Analysis of Initial Clinical ActivityOf the 23 efficacy evaluable patients in the monotherapy cohort, complete responses (CRs) were observed in 1 patient (DLBCL) and 3 partial responses observed (TCL), with an overall response rate (ORR) of 17.4% (4 of 23). Of the 13 patients in the combination cohort who were evaluable for efficacy, complete responses (CRs) were observed in 3 patients (2 DLBCL, 1 MCL) and 2 partial responses (PRs) observed (DLBCL and CLL) with an overall response rate (ORR) of 38.5% (5 of 13). The above-noted presentation can be found at Publications - Prelude Therapeutics (preludetx.com). “We believe the clinical data presented today with PRT2527 confirm our hypothesis that a highly selective and potent inhibitor of CDK9 has the potential to offer meaningful clinical activity for patients with hematologic malignancies, while avoiding the off-target toxicities observed with less selective agents,” stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. “However, given the significant progress and potential of our SMARCA degrader programs that are currently advancing in the clinic, along with our productive discovery organization, we plan to focus our resources towards the continued advancement of those programs. As a result, we will only advance the CDK9 program with a partner beyond completion of the current ongoing Phase 1 study.” About Prelude Therapeutics Prelude Therapeutics is a leading precision oncology company developing innovative medicines in areas of high unmet need for cancer patients. Our pipeline is comprised of several novel drug candidates including first-in-class, highly selective IV and oral SMARCA2 degraders, and a potentially best-in-class CDK9 inhibitor. We are also leveraging our expertise in targeted protein degradation to discover, develop and commercialize next generation degrader antibody conjugates (Precision ADCs) with partners. We are on a mission to extend the promise of precision medicine to every cancer patient in need. For more information, visit preludetx.com.
