"With Prelude’s core competencies in cancer biology and medicinal chemistry, in approximately five years we have successfully created a highly differentiated diverse pipeline that includes five distinct targets and six proprietary small molecule compounds, each with best-in-class potential aimed at addressing clinically validated pathways for cancers with selectable underserved patients," stated Kris Vaddi, Ph.D., Chief Executive Officer of Prelude. "Given the clinical progress we made in 2021, we have made important strategic portfolio prioritization and resource allocation decisions focusing on select molecules and indications where we see the greatest need and most efficient path to establishing proof-of-concept. This includes selecting PRT811 as the lead candidate in our PRMT5 program and prioritizing development of the intravenous formulation of our MCL1 candidate, PRT1419, and rapidly selecting a Phase 2 dose for PRT2527, our CKD9 inhibitor, in selected patients with cancers dependent on CKD9."

"Our discovery team continued to exceed expectations by bringing two new candidates into our pipeline, a differentiated SMARCA2/BRM protein degrader and most recently, PRT3645, a differentiated, selective and highly brain penetrant CDK4/6 inhibitor. We remain on track to file Investigational New Drug applications for each of these molecules in 2022."

Dr. Vaddi added, "Dr. Jane Huang’s appointment as President and Chief Medical Officer strengthens our leadership team. Dr. Huang’s extensive experience in oncology drug development, strong associations within the oncology community and success in building high-performing clinical development and operational teams supports our commitment to discover and deliver safe and effective precision oncology medicines to patients with underserved cancers."

Program Highlights and 2022 Objectives

PRMT5: Prelude is prioritizing PRT811 for continued clinical development focusing on splicing mutated myeloid malignancies and solid tumors, including uveal melanoma, and IDH1 mutated high grade gliomas. Prelude intends to complete the data analyses of the ongoing expansion cohorts for PRT543, including adenoid cystic carcinoma (ACC). Prelude expects to report data for the PRMT5 program in 2H/2022.

MCL1: Prelude is prioritizing development of the intravenous (IV) formulation of PRT1419 which demonstrated a desirable pharmacokinetic, pharmacodynamic and safety profile with potential for differentiation from competitor compounds. Prelude plans to initiate a combination trial with venetoclax by mid-year and report data by year-end 2022.

CKD9: Prelude intends to complete enrollment in the Phase 1 dose escalation study and identify a recommended Phase 2 dose by 2H/2022.

CDK4/6: Prelude intends to file an Investigational New Drug (IND) application mid-year and initiate a Phase 1 trial in 2H/2022.

SMARCA2/BRM: Prelude plans to complete IND-enabling studies and submit an IND application by year-end 2022.

Corporate Update

On March 9, 2022, Prelude announced the appointment of Jane Huang, M.D., to the newly created position of President and Chief Medical Officer. Dr. Huang joins Prelude from BeiGene Ltd., where she served as Chief Medical Officer, Hematology. Currently, Dr. Huang serves as an Adjunct Clinical Assistant Professor in Thoracic Oncology at Stanford University.

Full Year 2021 Financial Results

Cash and Cash Equivalents: Cash and cash equivalents as of December 31, 2021 were $291.2 million. Following Prelude’s recently announced program prioritization initiatives, the Company has extended its cash guidance and anticipates that its existing cash, cash equivalents and marketable securities will fund Prelude’s operations into the second half of 2024.

Research and Development (R&D) Expenses: R&D expenses for the year ended December 31, 2021 increased $38.6 million to $86.8 million compared to $48.2 million for the year ended December 31, 2020. The increase year-over-year was primarily due to increased clinical research costs to support the advancement of Prelude’s clinical programs and related chemistry, manufacturing and other costs for the clinical trials, in addition to an increase in discovery-stage program expenses.

General and Administrative (G&A) Expenses: G&A expenses for the year ended December 31, 2021 increased by $16.4 million to $27.0 million compared to $10.6 million for the year ended December 31, 2020. The increase was primarily due to increased employee headcount and an increase in professional fees as Prelude expanded its operations to support R&D efforts and incurred additional costs associated with operating as a public company.

Net Loss: Net loss for the year ended December 31, 2021 was $111.7 million or $2.43 per share, compared with a net loss of $56.9 million, or $4.56 per share for the year ended December 31, 2020.

About the SIENDO Study

The Phase 3 SIENDO study (ENGOT-EN5/GOG-3055) is a multicenter, blinded, placebo-controlled, randomized study evaluating the efficacy and safety of selinexor as a maintenance therapy following chemotherapy in patients with advanced or recurrent endometrial cancer. The study enrolled 263 patients with primary stage IV or recurrent disease who had a partial or complete response after at least 12 weeks of standard taxane-platinum combination chemotherapy. Patients were randomized 2:1 to receive either maintenance therapy of 80mg of selinexor taken once weekly, or placebo, until disease progression. The primary endpoint of the study is statistically significant improvement of progression-free survival compared to placebo. The goal of the study was to demonstrate a hazard ratio of 0.6 or better. In partnership with Karyopharm, the study was initiated by the ENGOT group. In the U.S., the collaboration includes the GOG-F.

About Endometrial Cancer

Endometrial cancer is the most common cancer of the female reproductive organs in the U.S., with approximately 66,000 new cases expected in 2022 leading to nearly 13,000 deaths.1 In 2020, there were approximately 130,000 new cases and 29,000 deaths in Europe from endometrial cancer, while on a global scale there were 417,000 new cases and approximately 97,000 deaths.2 More than 90 percent of uterine body cancers occur in the endometrium, so the actual numbers for endometrial carcinoma cases and deaths are slightly lower than these estimates, which include both endometrial carcinomas and uterine sarcomas. Unlike other cancers that have decreased with preventative measures, endometrial cancer is on the rise.3 Risk factors include obesity, Type 2 diabetes, high-fat diets, use of tamoxifen and oral estrogens, and delayed menopause.4 While the majority of endometrial cancers are diagnosed at early stages, approximately 14,000 patients in the U.S. are diagnosed with advanced disease that cannot be fully removed using surgery.5 These patients, and those with recurrent disease, are treated with chemotherapy. Chemotherapy does not cure patients with endometrial cancer. The use of later lines of chemotherapy are intended to control symptoms rather than cure the disease. There are no approved therapies in the maintenance setting for patients with advanced or recurrent endometrial cancer. The current standard of care is a "watch and wait" approach.6

About XPOVIO (selinexor)

XPOVIO is a first-in-class, oral exportin 1 (XPO1) inhibitor and the first of Karyopharm’s Selective Inhibitor of Nuclear Export (SINE) compounds to be approved for the treatment of cancer. XPOVIO functions by selectively binding to and inhibiting the nuclear export protein XPO1. XPOVIO is approved in the U.S. and marketed by Karyopharm in multiple oncology indications, including: (i) in combination with Velcade (bortezomib) and dexamethasone (XVd) in patients with multiple myeloma after at least one prior therapy; (ii) in combination with dexamethasone in patients with heavily pre-treated multiple myeloma; and (iii) in patients with diffuse large B-cell lymphoma (DLBCL), including DLBCL arising from follicular lymphoma, after at least two lines of systemic therapy. XPOVIO (also known as NEXPOVIO in certain countries) has received regulatory approvals in a growing number of ex-U.S. territories and countries, including Europe, the United Kingdom, China, South Korea and Israel, and is marketed in those areas by Karyopharm’s global partners. Selinexor is also being investigated in several other mid- and late-stage clinical trials across multiple high unmet need cancer indications, including myelofibrosis.

*Expressed in Canadian dollars, unless otherwise indicated.

Dr. Jennifer Bath, CEO of ImmunoPrecise, stated, "We are pleased with both the progress and continued execution of IPA’s strategic operating plan this quarter. In filling key roles within the organization’s sales and marketing teams, we believe we have provided the critical infrastructure to ramp growth of the commercial business. Consequently, project revenues in the CRO business increased a healthy 22.6% in the period, and we remain optimistic in our ability to grow revenues organically through existing clients and through new business wins alike. Additionally, we are moving the development of Polytope (TATX-03), Talem’s lead pipeline asset, forward on multiple fronts both in-house and through external partnering."

"TATX-03, currently in pre-IND phase — is tracking well against development timelines. As such, we expect to submit an investigational new drug application (IND) with the FDA by the third quarter of the calendar year. A highlight of this development program has been the absence of any significant regulatory hurdles to date, as we believe IPA’s conservative development and working in lockstep with the FDA inquiry process has paid off. This is against the backdrop of a rapidly evolving regulatory framework required to address the shifting future landscape around the fight against COVID-19. In tandem to the Company’s independent development efforts, we have also recently announced a partnering agreement with Elektrofi, to participate in a U.S. Defense Health Agency (DHA) funded program that will leverage funds from Elektrofi’s contract with the DHA Small Business Innovation Research program with the U.S. Department of Defense (DoD)," concluded Dr. Bath.

Recent Third Quarter Fiscal 2022 Operational Highlights

• IPA was selected to work with Elektrofi on COVID-19 therapeutic delivery and future pandemic preparation under SBIR contract from Defense Health Agency (DHA) within the US Department of Defense
• Polytope TATX-03 aggregate program update:

o No pharmacokinetic aberrations in in vivo animal model study.
o Injection with TATX-03 is well tolerated – with a significant safety margin and no clinical signs of toxicity.
o Maximum tolerated dose study evaluating up to a 12.5-fold higher amount than the highest dose anticipated for use in humans did not uncover any observable clinical signs of toxicity.
o SARS-CoV-2 PolyTope antibody cocktail retains in vitro binding efficacy against viral variants-of-concern tested to date.
o Initiated assessment of retention of binding to cell-associated Omicron spike protein variant (B.1.1.529).
o Improved protein homogeneity in PolyTope antibody cocktail for production purposes.
o Demonstrated in vitro pseudovirus assays, PolyTope advanced immunotherapeutic TATX-03 prevents infection of cells by SARS-CoV-2 variant-of-concern, Omicron, and all variants of concern tested to date.
o Established manufacturing collaboration with ChemPartner Biologics for PolyTope TATX-03 Antibody Cocktail.

• Talem Therapeutic filed a non-provisional U.S. patent application and concurrent international PCT (Patent Cooperation Treaty) and other national patent applications relating to the discovery of PolyTope TATX-03, its in vitro and in vivo effects, and therapeutic use.
• Leased future new space for laboratory expansion at IPA Europe in a new multi-tenant biotech Center of Excellence at the Pivot Park Campus in Oss, Netherlands.

"In 2021, we made significant progress towards our goal of advancing our lead program CYT-0851 in the clinic with the completion of a dose escalation study and identification of the recommended Phase 2 dose. Our interim analysis demonstrated anti-tumor effects with disease control and responses in heavily pretreated and progressing lymphoma and solid tumor patients, with a safety profile consisting primarily of mild adverse events," said Markus Renschler, MD, President and Chief Executive Officer of Cyteir. "We are now dosing patients in the Phase 2 monotherapy expansion cohorts and have begun Phase 1 combination therapy cohorts. We expect interim safety and efficacy data read-outs from these cohorts this year that may allow us to design one or more potentially registrational trials. We continue to invest in our pipeline and are advancing two new targets from our synthetic lethality DNA damage response platform toward the clinic."

Fourth Quarter and Full Year 2021 Accomplishments

Advanced CYT-0851 Clinical Program

Cyteir completed the dose-escalation portion of the first-in-human Phase 1/2 trial of CYT-0851 up to the maximum feasible daily dose of 1200 mg and determined the maximum tolerated dose of 600 mg per day. The recommended Phase 2 dose was identified as 400 mg per day. An interim analysis of the Phase 1 portion was presented in an oral session at the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) meeting. In a heavily pretreated and progressing patient group typical of Phase 1 studies, we demonstrated disease control in 20 of 46 response evaluable patients, including three responses in non-Hodgkin lymphoma and soft tissue sarcoma. No patient at or below the recommended Phase 2 dose discontinued treatment for treatment-related adverse events. The three most common treatment-related adverse events were fatigue (21% of patients), hyperuricemia (11%), and nausea (11%). There was no clinically significant myelosuppression.
We began enrolling patients in six disease-specific Phase 2 expansion cohorts with monotherapy in hematologic malignancies and solid tumors. In January 2022, the first patient was dosed. Completion of stage 1 of this study is expected before the end of 2022.
Simultaneously, we initiated a Phase 1 combination study of CYT-0851 with three standard-of-care regimens: rituximab plus bendamustine, gemcitabine and capecitabine, in both hematologic malignancies and solid tumors. In January 2022, we dosed the first patient in the study, and we are currently enrolling additional patients. Initial safety data from this combination study is expected before the end of 2022.
In total for our CYT-0851 Phase 1/2 trial, we are now actively enrolling nine patient cohorts in both monotherapy and combination therapy with interim safety results expected in 2022.
Advanced DNA Damage Response (DDR) Platform

In 2021, we initiated two additional drug discovery projects focused on identifying inhibitors of DNA damage repair. The first of these undisclosed targets (Target 2) plays a key role in Non-Homologous End Joining (NHEJ) and the second (Target 3) in Microhomology-Mediated End Joining (MMEJ) DNA repair pathways. For both targeted drug discovery projects, we have identified subsets of cancers that, we believe, uniquely depend on the target of interest for their survival and we are working to identify patient selection biomarkers to identify these cancer subsets for use in drug candidate development. Both undisclosed target projects are currently in lead generation, and we anticipate reaching the drug candidate nomination stage in 2023.
We expect to complete IND-enabling studies for CYT-1853 in the first half of 2022 and if the data supports an overall risk-benefit improvement and differentiation from CYT-0851, we plan to file an IND application with the FDA before the end of 2022.
Efficient execution of research and clinical strategy with cash runway into 2024

Ended 2021 with approximately $190 million in cash and cash equivalents with cash runway expected to extend into 2024
Continued investment in our clinical and preclinical portfolio
Progress achieved in key clinical milestones, including advancing CYT-0851 monotherapy to Phase 2 and initiating Phase 1 combination therapy study

Continue to elucidate CYT-0851’s molecular target and mechanism of action
Lead optimization of NHEJ inhibitor leading to potential target nomination in 2023
Lead optimization of MMEJ inhibitor leading to potential target nomination in 2023
Fourth Quarter and Full Year 2021 Financial Results

Cash and cash equivalents: Cash and cash equivalents as of December 31, 2021 were $189.7 million, which are expected to fund planned operations into 2024.

Research and development (R&D) expenses: R&D expenses were $8.3 million for the fourth quarter of 2021 versus $3.9 million for the same period in 2020 and $31.0 million for the full year 2021 versus $16.8 million for full year 2020. The year-over-year increase in R&D spending in the comparative periods was due primarily to increased research activity, clinical trial expenses and headcount, including initiation of Phase 1 and Phase 2 studies for our product CYT-0851.

General and administrative (G&A) expenses: G&A expenses were $3.6 million for the fourth quarter of 2021 compared to $1.5 million for the same period in 2020 and $11.3 million for the full year 2021 compared to $4.2 million for full year 2020. The year-over-year increase in G&A expenses in the comparative periods was primarily due to employee-related costs, as well as other administrative expenses associated with company growth and operating as a public company.

Net loss: Net loss was $11.8 million, or $0.34 per share, in the fourth quarter of 2021 compared to $5.4 million, or $2.92 per share, for the same period in 2020. For the full year 2021, net loss was $42.1 million, or $2.16 per share compared to $20.8 million, or $13.60 per share for full year 2020.

"This agreement with Evergreen Theragnostics represents an important step forward for Clovis in our efforts to optimize our clinical development program for FAP-2286," said Patrick J. Mahaffy, President and CEO of Clovis Oncology. "We are enthusiastic about exploring the potential of FAP-2286 labeled with actinium-225 in our targeted radiopharmaceuticals program. Actinium-225 represents an emerging radionuclide that is generating significant interest for its potential for therapeutic use."

Actinium-225 (225Ac) is an alpha particle-emitting radionuclide uniquely suited to targeted radiotherapeutic applications based on its half-life of approximately 10 days, balancing the ability to deliver a meaningful dose of radiation to target tumors while allowing central manufacturing and distribution of 225Ac-FAP-2286. The high-energy radioactive decay emitted from tumor-targeted 225Ac delivery causes double-stranded DNA damage and cell death, however, given the limited distance traveled by alpha particles, damage is minimized to cells in the tumor mass and systemic toxicity is potentially limited. i,ii

Under the terms of the agreement, Evergreen will develop 225Ac-FAP-2286 at its facility in Springfield, N.J. The facility was purpose-built to develop and manufacture a variety of therapeutic radiopharmaceuticals, including those based on alpha-emitting isotopes such as 225Ac, from early development to commercial scale manufacturing.

"We are excited to support Clovis and its targeted radionuclide development program with the development of an actinium-225-labeled FAP-2286. Actinium-based radiotherapies offer the potential to play an important role in the fight against cancer," said James Cook, CEO of Evergreen Theragnostics. "We seek to provide a robust and efficient radiopharmaceutical manufacture, testing, and supply process for our partners from early-stage development through commercialization."

FAP-2286 is the first peptide-targeted radionuclide therapy (PTRT) and imaging agent targeting fibroblast activation protein (FAP) to enter clinical development. In the Phase 1/2 LuMIERE study (NCT04939610), the investigational therapeutic agent is linked to lutetium-177 labeled FAP-2286 (177Lu-FAP-2286). Lutetium-177 (177Lu) is a beta-particle-emitting radionuclide with established supply and distribution networks ideally suited for clinical development of a PTRT. FAP-2286 labeled with gallium-68 (68Ga-FAP-2286) is being used as an investigational imaging agent to identify patients with FAP-positive tumors appropriate for treatment with the therapeutic agent. FAP-2286 is the lead candidate in Clovis Oncology’s targeted radionuclide therapy (TRT) development program.

About FAP-2286

FAP-2286 is a clinical candidate under investigation as a peptide-targeted radionuclide therapy (PTRT) and imaging agent targeting fibroblast activation protein (FAP). FAP-2286 consists of two functional elements; a targeting peptide that binds to FAP and a site that can be used to attach radioactive isotopes for imaging and therapeutic use. High FAP expression has been shown in pancreatic ductal adenocarcinoma, cancer of unknown primary, salivary gland, mesothelioma, colon, bladder, sarcoma, squamous non–small cell lung, and squamous head and neck cancers. High FAP expression was detected in both primary and metastatic tumor samples and was independent of tumor stage or grade. Clovis holds US and global rights for FAP-2286 excluding Europe, Russia, Turkey, and Israel.

FAP-2286 is an unlicensed medical product.

About Targeted Radionuclide Therapy

Targeted radionuclide therapy is an emerging class of cancer therapeutics, which seeks to deliver radiation directly to the tumor while minimizing delivery of radiation to normal tissue. Targeted radionuclides are created by linking radioactive isotopes, also known as radionuclides, to targeting molecules (e.g., peptides, antibodies, small molecules) that can bind specifically to tumor cells or other cells in the tumor environment. Based on the radioactive isotope selected, the resulting agent can be used to image and/or treat certain types of cancer. Agents that can be adapted for both therapeutic and imaging use are known as "theranostics." Clovis, together with licensing partner 3B Pharmaceuticals, is developing a pipeline of novel, targeted radiotherapies for cancer treatment and imaging, including its lead candidate, FAP-2286, an investigational peptide-targeted radionuclide therapeutic (PTRT) and imaging agent, as well as three additional discovery-stage compounds.
