On December 10, 2023 Taiho Oncology, Inc. reported results of a U.S. real-world study of oral decitabine and cedazuridine (DEC-C) in patients with myelodysplastic syndromes (MDS), a rare form of blood cancer (Press release, Taiho, DEC 10, 2023, View Source [SID1234638386]). Results of the retrospective real-world analysis of use patterns for hypomethylating agents suggest oral DEC-C as a treatment option with the potential to reduce patient and caregiver burden, while maintaining patients on therapy. Data from the study were shared during an oral presentation (Abstract #548) at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting & Exposition.

"For patients with myelodysplastic syndromes, therapy with intravenous or subcutaneous hypomethylating agents has been associated with increased patient burden, which can adversely affect treatment compliance and, subsequently, outcomes," said Amer Zeidan, MBBS, MHS, Associate Professor of Medicine (Hematology), Yale School of Medicine, Interim Chief, Hematologic Malignancies, Yale Cancer Center and Smilow Cancer Hospital, and study investigator. "Previous studies have shown that oral decitabine and cedazuridine provides comparable safety and efficacy to parenteral HMAs,1,2,3 and what we found in this real-world study is that this oral therapy resulted in a trend for improved persistence as treatment extended beyond the first six months. Based on these results and the potential for reduced treatment burden, oral decitabine and cedazuridine may be a viable alternative to intravenous or subcutaneous HMAs."

In this study of 1,569 patients, 160 received oral DEC-C and 1,409 received intravenous/subcutaneous (IV/SC) HMAs. After matching, there were 158 patients in each treatment cohort. Longitudinal persistence – the accumulation of time from initiation to discontinuation of therapy4 – was comparable between the matched oral DEC-C and intravenous/subcutaneous HMA cohorts during the first 6 months post-index, with similar proportions receiving the maximum number of treatment cycles (based on a 28-day cycle) at each month following index (73.8% vs 71.1%, 46.5% vs 48.7% and 28.6% vs 24.8%, for 2, 4 and 6 months, respectively). However, a trend toward improved persistence with oral DEC-C versus intravenous/subcutaneous HMAs was observed in patients receiving treatment beyond 6 months (25.0% vs 17.0%, 18.5% vs 9.0% and 11.4% vs 7.6% for 8, 10 and 12 months, respectively). Mean time to discontinuation of treatment was numerically higher for the oral DEC-C users compared with the IV/SC HMA group (87.7 vs 82.0 days); however, the differences were not statistically significant.

"For many patients living with MDS, the potential for additional costs and time associated with travel for regular infusions can be a significant burden during a stressful time in their lives," said Tehseen Salimi, MD, MHA, Senior Vice President Medical Affairs, Taiho Oncology. "Our goal with this study was to measure the real-world impact of oral therapy. As a leader in the development of orally administered anti-cancer agents, Taiho Oncology is pleased to see how outcomes of this real-world study show some of the potential benefits of an oral therapy in myelodysplastic syndromes."

About the Study

This study was a retrospective analysis using the U.S. Cerner Enviza claims database; medical and prescription claims data for patients were linked to mortality data from Datavant. Adults aged ≥18 years, who were diagnosed with MDS and who had ≥1 claim for an HMA (oral DEC-C or IV/SC HMA) were included. Patients had variable follow-up after the index date and were followed until end of enrollment, death or end of study. Longitudinal persistence was assessed according to the number of cycles of therapy received during follow-up, where a cycle was defined as either 3-10 days of administration of index intravenous/subcutaneous HMA or one claim for oral DEC-C within a 28-day cycle.

About Myelodysplastic Syndromes
Myelodysplastic syndromes are a heterogeneous group of hematopoietic stem cell disorders characterized by dysplastic changes in myeloid, erythroid, and megakaryocytic progenitor cells, and associated with cytopenias affecting one or more of the three lineages. In the U.S., approximately 20,000 cases of MDS are reported every year,5 with an overall age-adjusted incidence rate of 4.0 cases per 100,000 population.6 MDS may progress into acute myeloid leukemia (AML) in approximately 30-40% of patients.7,8 The prognosis for MDS patients is poor; patients die from complications associated with cytopenias (infections and bleeding) or from transformation to AML.

The PERFORM trial is a first-in-human, multi-center, open-label, Phase I dose-finding study of ATG-031 in patients with advanced solid tumors or B-NHL. The study’s primary objective is to evaluate the safety and tolerability of ATG-031 as a monotherapy, and determine the appropriate dose for Phase II studies. The secondary objective is to characterize the pharmacology, evaluate the immunogenicity, and assess the preliminary efficacy of ATG-031.

"We are delighted that the PERFORM trial has successfully dosed its first patient in the U.S. CD24 is a target with great potential in regulating macrophage activities in tumor environment. Supported by the striking preclinical efficacy demonstrated by blocking CD24 in preclinical studies and a promising preclinical safety profile based on CD24’s limited expression in normal tissue, Antengene has quickly initiated the PERFORM study in the U.S. to further assess the safety and tolerability of ATG-031 in late stage cancer patients," said Dr. Amily Zhang, Antengene’s Chief Medical Officer. "Moving forward, we will continue to work closely with investigators at MD Anderson and three other clinical trial centers in the U.S. to bring clinical benefit to more patients as soon as possible."

"With the joint persistent efforts from Antengene’s internal teams, we have made great strides to the development of ATG-031, a first-in-class anti-CD24 monoclonal antibody targeting the novel ‘don’t eat me’ pathway, while making rapid progress with the clinical development of other core assets. To date, we have established close collaboration with more than 100 clinical trial centers in the U.S., Australia, and the Mainland of China," said Dr. Jay Mei, Antengene’s Founder, Chairman and CEO. "Remaining committed to our global innovation strategies and steadily expediting our clinical programs, we will focus on next generation novel treatments to address broad unmet medical needs post the current immune checkpoint inhibitors."

About ATG-031
ATG-031 is a first-in-class humanized CD24 monoclonal antibody which inhibits the "don’t eat me" signal and enhances macrophage-mediated phagocytosis of cancer cells. Tumor cells evade the surveillance of the human immune system by over-expressing "don’t eat me" surface proteins that signal macrophages to prevent the detection and phagocytosis of cancer cells. CD24 (cluster of differentiation 24) is a prominent "don’t eat me" signal that plays a significant role in tumor immune evasion by suppressing macrophage-mediated phagocytosis. Compared to CD47, another well-known "don’t eat me" target, CD24 has a more restricted distribution in normal tissue and higher expression in cancerous tissue. In addition，unlike CD47，CD24 is not expressed on human red blood cells，allowing for a wider therapeutic window and minimal on-target-off-tumor toxicity as a CD24-targeted therapy.

As a novel innate immune checkpoint, CD24 orchestrates immune evasion through its interaction with the inhibitory receptor Siglec-10 (sialic-acid-binding Ig-like lectin 10) expresses on tumor-associated macrophages (TAMs). Preclinical data presented in 2023 at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting (AACR 2023) demonstrated that ATG-031 can specifically bind to CD24 with nM affinity and block the interaction of CD24 and Siglec-10. Furthermore, ATG-031 induces efficient phagocytosis with a picomolar EC50 and stimulates the pro-inflammatory cytokines production by macrophages.

"We are excited to share these initial data for MP0533, where we see antileukemic activity, already at these low doses, with a favorable safety profile. We look forward to the continuation of this study and evaluating the full potential of MP0533 for patients," said Patrick Amstutz, CEO of Molecular Partners. "For the first time ever, a non-antibody-based T-cell engager shows clinical activity, opening the door for next-generation DARPin drugs, such as tetra-specifics and logic-gated molecules."

As of the data cut-off (October 24, 2023), 11 patients had been enrolled in the first four dosing regimens (DR) of the ongoing Phase 1/2a trial of MP0533 monotherapy in patients with relapsed/refractory acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS/AML). The trial enrollment remains on track with patients currently being treated in the fifth of seven dose-escalation cohorts planned.

MP0533 continues to demonstrate an acceptable safety profile across all four DRs studied. No dose-limiting toxicities (DLTs) were observed as of data cut-off, and all patients were able to receive their full dose of MP0533. The most frequently reported MP0533-related adverse events were infusion-related reactions and cytokine release syndrome (all Grade 1-2).

Two responders have been observed to date, including a patient achieving complete response (CR) in DR 4 and another patient with morphological leukemia-free state (MLFS) in DR 3 (initially identified as CRi at the time of abstract submission, data cutoff July 2023). These responses are particularly notable for having occurred at dose levels below those predicted for therapeutically relevant activity.

Details of the poster presenting these results from the ongoing Phase 1/2a trial of MP0533 at the 65th ASH (Free ASH Whitepaper) Annual Meeting and Exposition can be found below. The poster will be made available on Molecular Partners’ website after the presentation. For more information on the trial, please visit clinicaltrials.gov (NCT05673057).

Title: MP0533, a CD3-Engaging DARPin Targeting CD33, CD123, and CD70 in Patients with Relapsed/Refractory AML or MDS/AML: Preliminary Results of a Phase 1/2a Study
Session Location & Date: San Diego Convention Center, Halls G-H; Sunday, December 10, 2023

About MP0533
MP0533 is a novel, avidity-driven, tetra-specific T cell-engaging, half-life extended, DARPin, which simultaneously targets the tumor-associated antigens CD33, CD123 and CD70 as well as the immune activator CD3 on T cells. MP0533’s affinity to each tumor-associated antigen is tuned to preferentially kill AML cells which commonly co-express at least two of these three target antigens whereas most healthy blood cells only express one or none. MP0533’s unique avidity-driven mode of action therefore enables targeted T cell-mediated killing of AML cells while preserving a therapeutic window that minimizes damage to healthy cells.

On December 10, 2023 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported that new data from its CD20xCD3 T-cell engaging bispecific antibody program, including eight oral presentations, were presented at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting & Exposition, December 9-12, 2023 (Press release, Genentech, DEC 10, 2023, View Source [SID1234638382]). Based on 32-month and 3-year follow-ups of two pivotal studies for fixed-duration treatments of Columvi (glofitamab-gxbm) and Lunsumio (mosunetuzumab-axgb), respectively, data show that remissions were maintained in the majority of patients with heavily pre-treated lymphomas. Additionally, new early-phase data of novel Columvi or Lunsumio combination regimens support ongoing investigation in Phase III studies in earlier lines of diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL).

"Updated data from pivotal studies of Columvi and Lunsumio continue to provide compelling evidence for how fixed-duration therapies can deliver sustained, long-term benefit for people with difficult-to-treat lymphomas," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "Our data at ASH (Free ASH Whitepaper) also demonstrate progress in evaluating our bispecific antibodies in earlier stages of disease and additional types of lymphoma so more people can benefit from our therapies."

Longer follow-up data from pivotal studies of fixed-duration Columvi and Lunsumio show benefit is maintained beyond the end of treatment
Extended follow-up data from the pivotal Phase II NP30179 study of Columvi administered for up to 12 cycles (approximately eight months) in patients with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) who have received at least two prior lines of therapy showed favorable long-term outcomes. After a median follow-up of 32 months, 55% of patients with a complete response (CR) were in remission at 24 months. Most of these patients remained progression-free and alive 18 months after completing the fixed-duration treatment. In patients who had received prior chimeric antigen receptor (CAR) T-cell therapy, the median duration of CR was 22.0 months (95% confidence interval [CI]: 6.7–not reached). No new safety signals were observed since the previous analysis.

Data from a three-year follow-up analysis of the pivotal Phase II GO29781 study of Lunsumio in patients with R/R FL who have received at least two prior lines of therapy were presented. Results showed continued durable responses and a manageable safety profile after treatment (up to approximately 12 months), with 59% of patients completing treatment after eight cycles (approximately five months). 72.7% of patients with a CR were alive and without disease progression 30 months after their first response. In the overall population, median progression-free survival (PFS) was 24 months (95% CI: 12.0–not evaluable [NE]) and overall survival (OS) not yet reached. No new safety signals were observed since the previous analysis.

Additional data presented reinforce the potential of novel combination regimens in earlier treatment settings
Diffuse large B-cell lymphoma
Data from the Phase Ib/II GO40516 study of Lunsumio plus Polivy (polatuzumab vedotin-piiq) in patients with R/R LBCL were presented and simultaneously published in Nature Medicine. Results showed that at 24 months median follow-up, the median PFS was 11.4 months (95% CI: 6.2–18.7), and median OS was 23.3 months (95% CI: 14.8–NE), highlighting the combination’s potential in R/R LBCL. The overall safety profile of patients with R/R LBCL treated with Lunsumio plus Polivy was manageable. Cytokine release syndrome (CRS) events were generally low grade (Grade 1: 10.2%; Grade 2: 5.1%; Grade 3: 3.1%). Lunsumio in combination with Polivy is being evaluated as an outpatient therapy for patients with R/R DLBCL in the ongoing Phase III SUNMO study.

Results from both arms of the Phase Ib NP40126 study evaluating Columvi in combination with Rituxan (rituximab), cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), and Columvi in combination with Polivy plus Rituxan, cyclophosphamide, doxorubicin and prednisone (Pola+R-CHP) in previously untreated DLBCL were presented. After a median of 12 months follow-up, data from the Columvi plus Pola+R-CHP arm showed that 91.7% of patients had a CR with no progression observed. Of the patients with a CR, 95.5% were still in remission, with a 12-month PFS rate of 91.5%. Safety profiles were highly consistent with earlier analyses from this study. These data support the ongoing Phase III SKYGLO study in previously untreated DLBCL.

Follicular lymphoma
The Phase II MorningSun study, evaluating a subcutaneous (SC) formulation of Lunsumio in patients with selected B-cell non-Hodgkin’s lymphomas , showed that SC Lunsumio is active and has a manageable safety profile in patients with first-line (1L) low-tumor burden FL. Data showed that 83.3% of patients achieved a complete metabolic response (95% CI: 62.6-95.3), and responses were ongoing at data cut-off. CRS was generally low grade (Grade 1: 36.7%; Grade 2: 6.7%) and occurred in cycle one only. Subcutaneous Lunsumio is also being investigated in combination with oral lenalidomide in 1L FL in the Phase Ib/II CO41942 study. New data demonstrated promising efficacy and manageable safety; data showed that 89.2% of patients achieved a CR, and CRS events were either Grade 1 (47.5%) or 2 (2.5%), all of which were confined to cycles one to two. The data support further investigation of this SC formulation of Lunsumio and highlight its potential as a tailored monotherapy or combination outpatient therapy for FL, including in community practices.

Totality of data presented underscores the strength of Genentech’s broad, industry-leading development program, which aims to address the diverse needs, preferences and experiences of people with blood cancers
Both Columvi and Lunsumio are being investigated in Phase III studies that will expand the understanding of their impact in earlier lines of treatment. This includes the Phase III STARGLO study evaluating Columvi in combination with GemOx in patients with R/R DLBCL who are ineligible for autologlous stem cell transplant; the Phase III SKYGLO study evaluating the efficacy and safety of Columvi plus Pola+R-CHP in previously untreated DLBCL; the Phase III GLOBRYTE study evaluating Columvi monotherapy in R/R mantle cell lymphoma; the Phase III SUNMO study investigating Lunsumio plus Polivy in R/R DLBCL; and the Phase III CELESTIMO study investigating Lunsumio plus lenalidomide in patients with R/R FL.

About Columvi (glofitamab-gxbm)
Columvi is a CD20xCD3 T-cell engaging bispecific antibody designed to target CD3 on the surface of T cells and CD20 on the surface of B cells. Columvi was designed with a novel 2:1 structural format. This T-cell engaging bispecific antibody is engineered to have one region that binds to CD3, a protein on T cells, a type of immune cell, and two regions that bind to CD20, a protein on B cells, which can be healthy or malignant. This dual-targeting brings the T cell in close proximity to the B cell, activating the release of cancer cell-killing proteins from the T cell. A clinical development program for Columvi is ongoing, investigating the molecule as a monotherapy and in combination with other medicines for the treatment of people with B-cell non-Hodgkin’s lymphomas, including diffuse large B-cell lymphoma and other blood cancers.

Columvi U.S. Indication

Columvi (glofitamab-gxbm) is a prescription medicine to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) or large B-cell lymphoma (LBCL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more prior treatments for their cancer.

It is not known if Columvi is safe and effective in children.

The conditional approval of Columvi is based on response rate and durability of response. There are ongoing studies to establish how well the drug works.

What is the most important information I should know about Columvi?

Columvi can cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with Columvi, and can also be serious and lead to death.

Call your healthcare provider or get emergency medical help right away if you develop any signs or symptoms of CRS, including:

fever of 100.4°F (38°C) or higher
chills or shaking
fast or irregular heartbeat
dizziness or light-headedness
trouble breathing
shortness of breath
Due to the risk of CRS, you will receive Columvi on a "step-up dosing schedule".

A single dose of a medicine called obinutuzumab will be given to you on the first day of your first treatment cycle (Day 1 of Cycle 1).
You will start the Columvi step-up dosing schedule a week after the obinutuzumab dose. The step-up dosing schedule is when you receive smaller "step-up" doses of Columvi on Day 8 and Day 15 of Cycle 1. This is to help reduce your risk of CRS. You should be hospitalized during your infusion and for 24 hours after receiving the first step-up dose on Day 8. You should be hospitalized during your infusion and for 24 hours after receiving the second step-up dose on Day 15 if you experienced CRS during the first step-up dose.
You will receive your first full dose of Columvi a week after the second step-up dose (this will be Day 1 of Cycle 2).
If your dose of Columvi is delayed for any reason, you may need to repeat the "step-up dosing schedule".
If you had more than mild CRS with your previous dose of Columvi, you should be hospitalized during and for 24 hours after receiving your next dose of Columvi.
Before each dose of Columvi, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.

Your healthcare provider will monitor you for CRS during treatment with Columvi and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with Columvi if you have severe side effects.

Carry the Columvi Patient Wallet Card with you at all times and show it to all of your healthcare providers. The Columvi Patient Wallet Card lists the signs and symptoms of CRS you should get emergency medical help for right away.

About Polivy (polatuzumab vedotin-piiq)

Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed specifically in the majority of B cells, an immune cell impacted in some types of non-Hodgkin’s lymphoma (NHL), making it a promising target for the development of new therapies. Polivy binds to cancer cells such as CD79b and destroys these B cells through the delivery of an anti-cancer agent, which is thought to minimize the effects on normal cells. Polivy is being developed by Genentech using Seagen ADC technology and is currently being investigated for the treatment of several types of NHL.

Polivy U.S. Indication
Polivy is a prescription medicine used with other medicines (a rituximab product, cyclophosphamide, doxorubicin, and prednisone) as a first treatment for adults who have moderate to high risk diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS) or high-grade B-cell lymphoma (HGBL).

Polivy is a prescription medicine used with other medicines, bendamustine and a rituximab product, to treat DLBCL in adults who have progressed after at least 2 prior therapies.
