"In 2021, Rubius Therapeutics demonstrated strong execution in advancing our clinical oncology pipeline and showing preclinical proof of concept of our tolerance induction approach in autoimmunity that could extend well beyond type 1 diabetes to other T cell-mediated diseases," said Pablo J. Cagnoni, M.D., president and chief executive officer, of Rubius Therapeutics. "With the initial clinical results from the Phase 1 clinical trial of RTX-240 in patients with advanced solid tumors reported in March 2021, we provided clinical validation of the RED PLATFORM and increased our likelihood of success across our entire oncology pipeline of Red Cell Therapeutics. With multiple data milestones on the horizon in 2022, we are on the cusp of potentially further validating the RED PLATFORM and benefiting an even greater number of patients."

Anticipated 2022 Catalysts and Operational Objectives

Enabling rapid and repeatable parallel generation of therapeutic candidates with the programmable RED PLATFORM
1,000 different therapeutic proteins biologically engineered since platform inception, underscoring the highly versatile and programmable nature of the platform
The platform creates multiple modalities for the treatment of cancer and autoimmune disease and the ability to express hundreds of thousands of copies of therapeutic proteins on or within the cell to access numerous immune pathways
Achieved clinical validation of the RED PLATFORM with initial clinical results from the single-agent RTX-240 Phase 1 clinical trial in advanced solid tumors, reported in March 2021
RCTs are well tolerated, induce the desired biological effect and generate clinical benefit in certain patients with advanced solid tumors
Advancing next generation artificial antigen-presenting cells (aAPCs) with loadable MHC Class I, enabling the presentation of multiple antigens on a single RCT and broadening the potential patient population with a library of HLA types
Oncology

Broad Immune Stimulation

RTX-240

RTX-240 is an allogeneic, off-the-shelf cellular therapy product candidate that is engineered to simultaneously present hundreds of thousands of copies of the costimulatory molecule 4-1BB ligand (4-1BBL) and IL-15TP (trans-presentation of IL-15 on IL-15Rα) in their native forms. RTX-240 is designed to broadly stimulate the immune system by activating and expanding both NK and CD8+ memory T cells to generate a potent anti-tumor response.

Established clinical proof of concept of RTX-240 in advanced solid tumors, based on initial results reported in March 2021, potentially increasing the likelihood of clinical success across the oncology pipeline
Escalated the dose of single-agent RTX-240 in the Phase 1 solid tumor clinical trial to three doses of 5e10 cells followed by 1e10 cells until disease progression or unacceptable toxicity, based on no dose-limiting toxicities observed to date, a clear dose response in the increase of NK cells and other pharmacodynamic effects
Additional clinical results are expected from this trial and the Phase 1 arm in relapsed/refractory AML during the first quarter of 2022
The Company plans to initiate RTX-240 Phase 2 expansion cohorts in select solid tumor types during the first quarter of 2022
Continuing dose escalation in the RTX-240 Phase 1 combination study with pembrolizumab in patients with advanced solid tumors with initial clinical data expected during the second half of 2022
RTX-224

RTX-224 is an allogeneic, off-the-shelf cellular therapy product candidate that is engineered to express hundreds of thousands of copies of 4-1BBL and interleukin-12 (IL-12) on the cell surface. While the lead oncology product candidate, RTX-240, is designed to broadly stimulate the immune system by activating and expanding NK and CD8+ memory T cells, RTX-224 is expected to produce a broad and potent anti-tumor T cell response, an innate immune response and have anti-tumor activity in those tumor types with known sensitivity to T cell killing, including tumor types with high mutational burden, PD-L1 expression and known responsiveness to checkpoint inhibitors.

Expect to begin dosing patients in the Phase 1/2 clinical trial of RTX-224 in selected relapsed/refractory or locally advanced solid tumors during the first quarter of 2022
Select cancers include non-small cell lung cancer, cutaneous melanoma, head and neck squamous cell carcinoma, urothelial (bladder) carcinoma and triple-negative breast cancer
Presented preclinical data at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s (SITC) (Free SITC Whitepaper) 36th Annual Meeting in November 2021, demonstrating that the mouse surrogate of RTX-224, mRBC-224, generated potent anti-tumor activity in B16F10 melanoma models, intravenously and subcutaneously, that was associated with pharmacodynamic changes in the tumors, including activated CD8 + T cells, NK cells and macrophages
Antigen-Specific Immune Stimulation

RTX-321 Artificial Antigen-Presenting Cell (aAPC) Development Program for Human Papillomavirus (HPV) 16-Positive Cancers

RTX-321 is an allogeneic, off-the-shelf artificial aAPC therapy product candidate that is engineered to induce a tumor-specific immune response by expanding antigen-specific T cells. RTX-321 expresses hundreds of thousands of copies of an HPV peptide antigen bound to major histocompatibility complex class I proteins, the costimulatory molecule 4-1BBL and the cytokine IL-12 on the cell surface to mimic human T cell-APC interactions.

Continuing enrollment in the Phase 1 clinical trial of RTX-321 in patients with advanced HPV 16-positive cancers
Based on no dose limiting toxicities to date, the Company plans to dose escalate beyond the current cohort of 1e10 cells
Plan to report initial clinical results during the second half of 2022
Autoimmune Diseases and Type 1 Diabetes

Red Cell Therapeutics for the treatment of autoimmune disease are biologically engineered to express proteins and peptides inside the cell and are designed to be phagocytized, or ingested, by dendritic cells or macrophages to induce tolerance, retraining the immune system to no longer recognize these self-antigens as foreign.

Demonstrated tolerance induction and bystander suppression in stringent type 1 diabetes preclinical models
Established efficacy in the BDC2.5 adoptive transfer model with data supporting that repeated dosing extended duration of disease protection, reversed established inflammation, which is important for the treatment of existing autoimmunity, and induced two types of regulatory T cells, resulting in protection against re-challenge
Showed efficacy in non-obese diabetes (NOD) preclinical model
Results at 25 weeks exhibit bystander suppression by delivering only two antigens, indicating the mouse surrogate of RTX-T1D prevented or delayed disease caused by many autoantigens
These findings are potentially translatable beyond type 1 diabetes to multiple autoimmune diseases, including other Rubius’ high priority target indications, including multiple sclerosis and celiac disease.
Fully Owned Manufacturing

Increased cells produced per batch by four times in 50L bioreactors from 2020 to 2021, enabling uninterrupted clinical supply for three Phase 1 arms of the RTX-240 clinical trial and Phase 1 RTX-321 trial
Additional accomplishments include:
High success rate: greater than 90% lot success rate for RTX-240 and RTX-321 clinical supply in 2021
Hundreds of doses administered across three arms of RTX-240 Phase 1 and RTX-321 Phase 1 trials
High transduction efficiency: greater than 90% of cells are transduced with therapeutic proteins
Highly consistent protein expression (dual or triple)
Introduced frozen drug substance for RTX-321 and RTX-224, enabling inventory storage of greater than two years
Developing frozen drug product to further simplify supply chain with the goal of making our therapies available around the world
Bringing all product testing in-house to strengthen supply chain and reduce time-to-product release
Continuing to invest in the platform to improve productivity and efficiency
Scaling to 200L bioreactors by mid-2022 to support potential pivotal trial and eventual commercialization

On January 10, 2022 Fate Therapeutics, Inc. (NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for patients with cancer, reported that the U.S. Food and Drug Administration (FDA) has cleared the Company’s Investigational New Drug (IND) application for FT536, an off-the-shelf, multiplexed-engineered, iPSC-derived, chimeric antigen receptor (CAR) NK cell product candidate (Press release, Fate Therapeutics, JAN 10, 2022, View Source [SID1234598464]). FT536 is derived from a clonal master induced pluripotent stem cell (iPSC) line engineered with four functional elements, including a novel CAR that uniquely targets the α3 domain of the major histocompatibility complex (MHC) class I related proteins A (MICA) and B (MICB). MICA and MICB are stress proteins that are expressed at high levels on many solid tumors. The Company plans to initiate clinical investigation of FT536 as a monotherapy and in combination with tumor-targeting monoclonal antibody therapy for the treatment of multiple solid tumor indications.

"We are very pleased with our progress in bringing first-in-class, multiplexed-engineered NK cell product candidates to patients for the treatment of solid tumors. MICA and MICB are emerging as exciting pan-cancer immunotherapy targets across a wide range of solid tumors, and FT536 represents a novel therapeutic strategy designed to target these stress-induced ligands," said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. "With the proteolytic shedding of the α1 and α2 domains of MICA/B being recognized as a common tumor escape mechanism, we are encouraged that our novel CAR design, which uniquely targets the α3 domain of MICA/B, has shown the potential to overcome shedding and restore NK and T cell-mediated tumor immunity. We look forward to treating patients with FT536 as monotherapy and in combination with monoclonal antibody therapy to promote a multi-pronged attack against solid tumors."

FT536 also incorporates a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor, which has been modified to prevent its down-regulation and to enhance its binding to tumor-targeting antibodies; an IL-15 receptor fusion (IL-15RF) that augments NK cell activity; and the deletion of the CD38 gene (CD38KO), which promotes persistence and function in high oxidative stress environments such as the suppressive tumor microenvironment. The multi-center Phase 1 clinical trial of FT536 is designed to determine the maximum tolerated dose of FT536 and assess its safety and clinical activity as monotherapy and in combination with one of an array of five monoclonal antibodies for the treatment of advanced solid tumors. Eligible tumor types include advanced non-small cell lung cancer, colorectal cancer, head and neck cancer, gastric cancer, breast cancer, ovarian cancer, and pancreatic cancer.

The Phase 1 clinical protocol allows for administration of FT536 initially in up to two, 30-day cycles, with each cycle consisting of three days of conditioning chemotherapy and three weekly doses of FT536. Patients with clinical benefit may be re-treated with up to two additional cycles. Furthermore, for those patients that achieve initial clinical response, additional treatment with FT536 may be administered following disease progression. The off-the-shelf treatment regimen is designed to be administered in the outpatient setting.

The expression of MICA and MICB proteins, which is induced by cellular stress, damage or transformation, has been reported for many solid tumor types. Cytotoxic lymphocytes, such as NK cells and CD8+ T cells, can recognize and bind the membrane-distal α1 and α2 domains of MICA/B, activating a potent cytotoxic response. However, cancer cells frequently evade immune cell recognition by proteolytic shedding of the α1 and α2 domains of MICA/B. A recent publication in Science (DOI:10.1126/science.aao0505) by Kai W. Wucherpfennig, M.D., Ph.D., Chair of the Department of Cancer Immunology and Virology at the Dana-Farber Cancer Institute and co-leader of the Cancer Immunology Program at Dana-Farber / Harvard Cancer Center, demonstrated that antibody targeting of the MICA/B α3 domains specifically prevents MICA/B shedding and restores NK cell-mediated immunity. Additionally, in a more recent publication in Cancer Immunology Research (DOI: 10.1158/2326-6066.CIR-19-0483), Dr. Wucherpfennig also demonstrated that cancers with B2M and JAK1 inactivating mutations resulting in loss of MHC Class I expression can be effectively targeted with MICA/B α3 domain-specific antibodies to restore NK cell-mediated immunity against solid tumors resistant to cytotoxic T cells. The Company’s FT536 program is supported by an exclusive license from the Dana-Farber Cancer Institute to intellectual property covering novel antibody fragments binding MICA/B for iPSC-derived cellular therapeutics.

About Fate Therapeutics’ iPSC Product Platform
The Company’s proprietary induced pluripotent stem cell (iPSC) product platform enables mass production of off-the-shelf, engineered, homogeneous cell products that are designed to be administered with multiple doses to deliver more effective pharmacologic activity, including in combination with other cancer treatments. Human iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The Company’s first-of-kind approach involves engineering human iPSCs in a one-time genetic modification event and selecting a single engineered iPSC for maintenance as a clonal master iPSC line. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, clonal master iPSC lines are a renewable source for manufacturing cell therapy products which are well-defined and uniform in composition, can be mass produced at significant scale in a cost-effective manner, and can be delivered off-the-shelf for patient treatment. As a result, the Company’s platform is uniquely designed to overcome numerous limitations associated with the production of cell therapies using patient- or donor-sourced cells, which is logistically complex and expensive and is subject to batch-to-batch and cell-to-cell variability that can affect clinical safety and efficacy. Fate Therapeutics’ iPSC product platform is supported by an intellectual property portfolio of over 350 issued patents and 150 pending patent applications.

On January 10, 2022 Magenta Therapeutics (NASDAQ: MGTA), a clinical-stage biotechnology company developing novel medicines designed to bring the curative power of stem cell transplant to more patients, reported that progress across its portfolio of targeted conditioning and stem cell mobilization programs and set out its milestone expectations for both clinical and preclinical data in 2022 (Press release, Magenta Therapeutics, JAN 10, 2022, View Source [SID1234598463]).

"2022 will be an important year for the Magenta portfolio" said Jason Gardner, D. Phil., President and Chief Executive Officer, Magenta Therapeutics. "We believe we will clinically demonstrate that MGTA-117 targets and binds selectively to CD117-expressing cells, potently depletes those cells and the product profile will be well-tolerated in our Phase 1/2 clinical study. We have developed biomarker assays that we believe will provide early insights into the biologic activity of MGTA-117. We are also thrilled to introduce our second targeted conditioning program in the development pipeline, an antibody drug conjugate targeting CD45 which has the potential to deplete both stem cells and immune cells without chemotherapy. Finally, with our MGTA-145 program, we are focused on optimizing the collection yield of mobilized stem cells. We believe MGTA-145 can offer a faster and more reliable mobilization regimen for stem cell transplantation as well as ex vivo and in vivo gene therapies."

Targeted Conditioning

MGTA-117 Program:

2022 Clinical Data from Phase 1/2 Clinical Trial: Evaluating Target Selectivity, Potency and Tolerability. The MGTA-117 Phase 1/2 clinical trial is open for enrollment. This dose escalation clinical trial will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of MGTA-117 as a single dose in patients with relapsed/refractory Acute Myeloid Leukemia (AML) and Myelodysplasia-Excess Blasts (MDS-EB).

Specifically, dosing cohorts expected to enroll in 2022 will allow for evaluation of MGTA-117’s ability to:

selectively target CD117 as measured by receptor occupancy;
potently deplete CD117-expressing cells such as stem cells, progenitors, and tumor cells; and
rapidly clear from the body with a well-tolerated profile as determined by pharmacokinetic analysis and clinical chemistry tests, respectively.
Magenta’s preclinical evidence supports the MGTA-117 target selectivity, potency and tolerability profile. In GLP toxicology studies, MGTA-117 potently depleted stem cells at a dose level where there were no drug-related findings in hepatic, reproductive, neurologic, cardiovascular, or respiratory organs.

Phase 1/2 Clinical Trial Design for MGTA-117. MGTA-117 will be assessed in patients with relapsed/refractory AML and MDS-EB in a multi-center, open-label, single-ascending-dose trial. Patients in the first cohort will receive 0.02 mg/kg administered intravenously (IV), and subsequent cohort doses will be determined in accordance with a modified Fibonacci sequence.

Magenta will assess data from each cohort and, after collection of adequate safety, pharmacokinetic and pharmacodynamic data, Magenta intends to engage with the U.S. Food and Drug Administration (FDA) to transition to the primary target population of patients eligible for stem cell transplantation. In addition, Magenta plans to explore MGTA-117 as a targeted conditioning agent for stem cell gene therapies.

CD45-Antibody Drug Conjugate Program:

Magenta has initiated investigational new drug application-enabling studies on its second targeted conditioning program, an antibody drug conjugate (ADC) targeting CD45. Due to the expression of CD45 on stem cells and immune cells, Magenta’s CD45-ADC is designed to selectively target and deplete stem cells and lymphocytes, which could allow patients with blood cancers and autoimmune diseases to avoid use of chemotherapy prior to stem cell transplant. Magenta expects to have preclinical data from a dose ranging toxicology study in the second half of 2022.

Stem Cell Mobilization and Collection

MGTA-145 Dosing and Administration Optimization Clinical Trial. As previously disclosed, Magenta intends to initiate a dosing and administration optimization clinical trial with MGTA-145 in combination with plerixafor. Clinical data from a Phase 2 investigator-initiated clinical trial with 25 multiple myeloma patients showed that MGTA-145, in combination with plerixafor, mobilized a sufficient number of stem cells for transplantation in 88% of patients (22/25). In addition, all patients transplanted with cells mobilized by MGTA-145 plus plerixafor as of the data cut-off date had successful engraftment (18/18 patients) with prolonged durability through the 100-day follow-up period (13/13 patients). The regimen was generally well-tolerated. Magenta believes there are specific opportunities to further improve cell collection yield by adjustments to the regimen dosing, and administration timing. Magenta expects to generate data from this healthy subjects clinical trial in the second half of 2022.

Sickle Cell Disease (SCD) – Stem Cell Mobilization Phase 2 Clinical Trial. Magenta is advancing trial initiation activities. The trial is designed to evaluate mobilization and collection of stem cells in adults and adolescents with SCD. Magenta and its clinical collaboration partner, bluebird bio, will each characterize the collected cells. Magenta plans to gene-modify the cells and transplant them into established preclinical models to evaluate graft quality and engraftment. Data from this clinical trial could provide proof-of-concept for MGTA-145, in combination with plerixafor, as a first-line mobilization regimen for patients with SCD and, more broadly, across other gene therapy applications. Magenta expects to generate data from this clinical trial in the second half of 2022.

Cash Guidance

With focused allocation of capital and resources on both clinical stage programs and CD45-ADC, Magenta now expects its cash reserves to fund its operating plan into the fourth quarter of 2023. Magenta ended 2021 with approximately $162 million of cash, cash equivalents, and marketable securities (unaudited).

About CERPASS
CERPASS is Replimune’s registration-directed randomized, global Phase 2 clinical study to compare the effects of Libtayo alone versus a combination of Libtayo and Replimune’s investigational oncolytic immunotherapy RP1. The clinical trial is enrolling enroll 180 patients with locally advanced or metastatic cutaneous squamous cell carcinoma (CSCC) who are naïve to anti-PD-1 therapy. The clinical trial will evaluate complete response (CR) rate and overall response rate (ORR) as its two primary efficacy endpoints as assessed by independent review, as well as duration of response, progression-free survival (PFS), and overall survival (OS) as secondary endpoints. The study is being conducted under a clinical trial collaboration agreement with Regeneron in which the costs of the trial are shared and full commercial rights retained by Replimune. Libtayo is being jointly developed by Regeneron and Sanofi.
Libtayo is a registered trademark of Regeneron.

About IGNYTE
IGNYTE is Replimune’s multi-cohort Phase 1/2 trial of RP1 plus Opdivo. There are 4 tumor specific cohorts currently enrolling in this clinical trial including a 125-patient cohort in anti-PD-1 failed cutaneous melanoma. This cohort was initiated after completing enrollment in a prior Phase 2 cohort in the same clinical trial of approximately 30 patients with melanoma. The additional cohorts are in non-melanoma skin cancers which includes both naïve and anti-PD-1 failed CSCC, in anti-PD1 failed microsatellite instability high, or MSI-H/dMMR tumors and anti-PD(L)-1 failed non-small cell lung cancer, or NSCLC. This trial is being conducted under a collaboration and supply agreement with Bristol-Myers Squibb Company. Opdivo is a registered trademark of Bristol-Myers Squibb Company.

About RP1
RP1 is Replimune’s lead product candidate and is based on a proprietary new strain of herpes simplex virus engineered and genetically armed to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response.

About RP2 & RP3
RP2 and RP3 are derivatives of RP1 that express additional immune-activating proteins. RP2 expresses an anti-CTLA-4 antibody-like molecule and RP3 additionally expresses the immune co-stimulatory pathway activating proteins CD40L and 4-1BBL. RP2 and RP3 are intended to provide targeted and potent delivery of these proteins to the sites of immune response initiation in the tumor and draining lymph nodes, with the goal of focusing systemic immune-based efficacy on tumors and limiting off-target toxicity
