Prelude Announces Strategic Pipeline Progress and Updates, including its Partnership with AbCellera, and Reports Third Quarter Financial Results
Prioritization of its first-in-class SMARCA2 degrader and potentially best-in-class CDK9 inhibitor programs for continued clinical development
Enters partnership with AbCellera to develop a portfolio of precision ADCs with first program being a SMARCA degrader-antibody conjugate
Cash runway into 2026 with $230.5 million of cash, cash equivalents and marketable securities
WILMINGTON, Del. – November 1, 2023 – Prelude Therapeutics Incorporated (Prelude) (Nasdaq: PRLD), a clinical-stage precision oncology company, today provides strategic pipeline updates and reports third quarter financial results.
Recent clinical progress and strategic prioritization of the pipeline include:
“We made significant progress in the third quarter with our four clinical stage molecules and, as planned, conducted a rigorous assessment of each program. Based on this assessment, we are prioritizing our resources on our first-in-class SMARCA2 degrader molecules, IV and oral, and our potential best-in-class CDK9 inhibitor program,” stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. “We are confident that these two programs represent compelling opportunities for demonstrating clinical proof-of-concept in 2024, for advancing into potential Phase 2/3 registration studies, and for becoming important new medicines. This decision reflects our dual commitment to deliver differentiated treatments to patients and to build significant and sustainable value for our shareholders.”
Dr. Vaddi continued, “Regarding our recently announced partnership with AbCellera, this alliance combines our strengths in small molecule drug discovery and development with AbCellera’s powerful antibody discovery engine. We plan to build a portfolio of first-in-class precision ADCs that will utilize highly selective and potent small molecules and degraders as payloads targeting critical oncogenic pathways. We have already started work on our first program with a SMARCA payload on an antibody selected from a lead panel of antibodies previously discovered by AbCellera. We believe that this program further expands the potential of our SMARCA2 selective degraders.”
Jane Huang, MD, President and Chief Medical Officer, said, “Our SMARCA2 program continues to receive strong interest and support from investigators as patients with deleterious SMARCA4 mutations do not have effective treatment options. Based on our ability to select patients using a readily available biomarker, we have been able to enroll efficiently our ongoing Phase 1 clinical trial for PRT3789. We are encouraged not only by the pace of enrollment but also by early clinical data demonstrating selective degradation of SMARCA2, and by the compound’s safety profile to date. Our top priority is to generate initial clinical proof-of-concept data in 2024. Provided these results are as we expect, we anticipate advancing the compound into a registrational Phase 2/3 trial thereafter.”
“For our CDK9 inhibitor PRT2527, we are also encouraged by the emerging data in both solid and hematological cancers. These data demonstrate that our highly targeted compound has been generally safe and well-tolerated with a strong inhibition of the pathway required for efficacy in preclinical models and is well-differentiated from other CDK9 inhibitors. These results strengthen our confidence in its potential best-in-class profile and position us to be the most advanced CDK9 inhibitor for patients with B-cell malignancies and AML. Our key objective is to establish clinical proof-of concept data in both the monotherapy setting and in combinations in 2024.”
SMARCA Programs
PRT3789- SMARCA2 Targeted IV Protein Degrader
PRT3789 is a first-in-class highly selective degrader of SMARCA2 protein, which along with SMARCA4, controls gene regulation through chromatin remodeling. Cancer cells with SMARCA4 mutations are dependent on SMARCA2 for their growth and survival and selectively degrading SMARCA2 induces cell death in cancer cells while sparing normal cells. PRT3789 is efficacious and well-tolerated in preclinical models of SMARCA4 deleted/mutated cancers as
monotherapy and in combination with standard of care. Prelude believes a selective SMARCA2 degrader has the potential to be of benefit in up to 70,000 US/EU cancer patients with the SMARCA4 mutation.
A Phase 1 multi-dose escalation clinical trial of PRT3789 is ongoing (NCT05639751) in biomarker-selected SMARCA4 mutated cancers. Prelude intends to evaluate PRT3789 as monotherapy as well as in combination and plans to share initial Phase 1 data in mid-2024.
SMARCA2 - Oral Program
Prelude recently nominated a potent, orally bioavailable and highly selective SMARCA2 degrader candidate. This compound is >1000x selective for SMARCA2 over SMARCA4 and is currently in IND-enabling studies. Prelude expects to file an IND in the first half of 2024.
SMARCA - Precision ADC
Prelude and its partner AbCellera began work on an early-stage discovery program involving potent degraders of the SMARCA family of proteins as payloads for novel antibodies targeting tumor specific antigens. Given the potent anti-tumor activity of these molecules in pre-clinical models of cancers beyond those targeted by our SMARCA2 selective degraders, we believe that these precision ADCs have the potential to extend the therapeutic utility of this class.
CDK9 Inhibitor Program
Prelude believes its highly selective CDK9 inhibitor, PRT2527, has the potential to avoid off-target toxicities, achieve substantial clinical activity and become the best-in-class CDK9 inhibitor.
PRT2527 has completed a Phase 1 dose escalation study (NCT05159518) in patients with solid tumors. In this trial, PRT2527 was shown to achieve high levels of target inhibition and to potentially be better tolerated than existing CDK9 inhibitors, specifically manageable neutropenia and an absence of meaningful gastrointestinal events or hepatotoxicity.
The observed dose-dependent downregulation of MYC and MCL1 mRNA expression, CDK9 transcriptional targets, was consistent with the degree of target engagement required for preclinical efficacy. As predicted by the preclinical models, 12 mg/m2 QW dosing showed optimal target inhibition and has been selected as the optimal dose. The overall safety profile observed in this study supports further development of PRT2527 in hematologic malignancies (NCT05665530) and this study is currently ongoing with initial clinical data expected in mid 2024.
MCL1 Inhibitor Program
Prelude has concluded Phase 1 development of PRT1419 and established a confirmation dose in hematological cancers. Based on the potential to address the intended patient populations with the CDK9 inhibitor which potently inhibits MCL-1, Prelude has made a decision to prioritize its CDK9 inhibitor, PRT2527, over PRT1419.
Next Generation CDK4/6 Inhibitor Program
PRT3645 is a highly potent and selective next generation CDK4/6 inhibitor with the potential to provide improved safety and tolerability outcomes and to achieve higher, more effective brain and tissue penetration than current CDK4/6 inhibitors.
Prelude intends to complete the dose escalation portion of the Phase 1 clinical trial of PRT3645 this year. Prelude is actively exploring continued clinical development with external partners.
At the recent AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, Prelude presented data showing that treatment with PRT3645 was associated with substantial decreases in both pRb and Ki67 expression, indicating a dose-dependent target engagement at the doses evaluated. Also, PRT3645 treatment was generally well tolerated in the initial three dose cohorts of patients with no clinically meaningful gastrointestinal, hematologic or neurological events reported to date, reflecting its enhanced selectivity profile.
Third Quarter Financial Results
Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents, and marketable securities as of September 30, 2023, were $230.5 million. Prelude anticipates that its existing cash, cash equivalents and marketable securities will fund Prelude’s operations into 2026.
Research and Development (R&D) Expenses: For the third quarter of 2023, R&D expenses increased to $26.3 million from $22.9 million for the prior year period. R&D expenses increased primarily due to the timing of our clinical research programs. We expect our R&D expenses to vary from quarter to quarter, primarily due to the timing of our clinical development activities.
General and Administrative (G&A) Expenses: For the third quarter of 2023, G&A expenses decreased to $7.1 million from $7.5 million for the prior year period. G&A expenses decreased reflecting Prelude’s continued careful management of its G&A expenses.
Net Loss: For the three months ended September 30, 2023, net loss was $30.6 million, or $0.45 per share compared to $30.0 million, or $0.63 per share, for the prior year period. Included in the net loss for the quarter ended September 30, 2023, was $6.7 million of non-cash expense related to the impact of expensing share-based payments, including employee stock options, as compared to $6.4 million for the same period in 2022.
