On December 10, 2023 Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) reported that the primary analysis of the Phase III HAVEN 7 study reinforced the efficacy and safety of Hemlibra (generic name: emicizumab) in previously untreated or minimally treated infants with severe hemophilia A without factor VIII inhibitors (Press release, Chugai, DEC 10, 2023, View Source;category= [SID1234638380]). Results showed that Hemlibra achieved meaningful bleed control in babies up to 12 months of age, and was well tolerated.1 The new data were presented at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition taking place 9-12 December 2023, in San Diego, California, and included in the press program.

"Hemlibra, which can be administered subcutaneously, is an option to reduce the treatment burden for infants who have difficulty with intravenous administration in the treatment of severe hemophilia A to prevent bleeding. In this study, Hemlibra demonstrated effective bleeding control in infants for the first time. This complements data across a wide range of ages shown in previous clinical trials and supports earlier initiation of Hemlibra treatment aimed at preventing bleeding in infants. We remain committed to building evidence including long-term data to support the safe use of this drug for those who need it," said Dr. Osamu Okuda, Chugai’s President and CEO.

The burden of severe hemophilia A in babies and on their parents and caregivers is significant. The World Federation of Hemophilia treatment guidelines consider the standard of care in hemophilia to be regular prophylaxis initiated at a young age, as studies have shown this improves long-term outcomes, while reducing the risk of intracranial hemorrhage.2-4 However, for many babies with hemophilia A, prophylaxis is not started until after the first year of life.5-8 Hemlibra, which is already approved and being used to treat babies with hemophilia A, provides a flexible treatment option that can be administered subcutaneously from birth at different dosing frequencies for maintenance dosing.9

The HAVEN 7 study is a Phase III, descriptive, single-arm study, set up in collaboration with the hemophilia A community to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of subcutaneous Hemlibra in infants with severe hemophilia A without factor VIII inhibitors. These results, which included data from 55 participants, showed that at 101.9 weeks median follow-up, 54.5% of participants (n=30) did not have any bleeds that required treatment, while 16.4% (n=9) did not have any treated or untreated bleeds at all. There were no spontaneous bleeds requiring treatment in any participant, and all treated bleeds were as a result of trauma. A total of 207 bleeds occurred in 46 participants (83.6%); 87.9% of these were as a result of trauma. Model-based annualized bleeding rate (95% CI) was 0.4 (0.30-0.63) for treated bleeds. No new safety signals were observed and there were no treatment-related serious adverse events, intracranial hemorrhages or deaths reported. 3.6% of participants (n=2) tested positive for factor VIII inhibitors which may be a consequence of reduced factor VIII usage in participants treated with Hemlibra, and no participant tested positive for anti-drug antibodies.1 Results were consistent with positive results from the interim analysis and from previous Phase III HAVEN studies.10-14

The results of additional research on biomarkers in the HAVEN 7 study were also presented at ASH (Free ASH Whitepaper), and were supportive of the study’s primary efficacy analysis. This additional research showed that the pharmacodynamic profiles of Hemlibra in babies were consistent with those previously observed in older children and adults with hemophilia A. The data showed that Hemlibra exhibits the expected pharmacodynamic response, despite the reduced presence of the clotting factors that Hemlibra binds to in this age group.15

The HAVEN 7 study results complement data from the broader, pivotal HAVEN clinical program, providing insights into the evolution of hemophilia A in babies, and the impact of initiating preventative treatment from birth. The primary analysis is being followed by a seven year extension period.1

About Hemlibra
Hemlibra is a bispecific monoclonal antibody created with Chugai’s proprietary antibody engineering technologies. The drug is designed to bind factor IXa and factor X. In doing so, Hemlibra provides the cofactor function of factor VIII in people with hemophilia A, who either lack or have impaired coagulation function of factor VIII.16,17 The product was approved by the U.S. Food and Drug Administration (FDA) in November 2017, for the first time in the world, for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients with hemophilia A (congenital factor VIII deficiency) with factor VIII inhibitors. Hemlibra has been approved in more than 115 countries for congenital hemophilia A with and without factor VIII inhibitors. In Japan, it was first approved in March 2018 for congenital hemophilia A with factor VIII inhibitors, and its indication was later expanded to include congenital hemophilia A without factor VIII inhibitors, and acquired hemophilia A.

On December 10, 2023 ImmunoGen Inc. (Nasdaq: IMGN), a leader in the expanding field of antibody-drug conjugates (ADCs) for the treatment of cancer, reported new safety and efficacy findings from the newly diagnosed (ND) cohorts of the Phase 1b/2 study of pivekimab sunirine (pivekimab) in combination with azacitidine (Vidaza) and venetoclax (Venclexta), (pivekimab triplet) in patients with ND acute myeloid leukemia (AML) (Press release, ImmunoGen, DEC 10, 2023, View Source [SID1234638396]). These findings will be presented in a poster session at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in San Diego, California.

"We are pleased to share these new findings at ASH (Free ASH Whitepaper), which demonstrate encouraging anti-leukemia activity of the pivekimab triplet in newly diagnosed AML, a disease in which long-term survival unfortunately remains limited," said Naval Daver, MD, Associate Professor in the Department of Leukemia at The University of Texas MD Anderson Cancer Center. "The MRD negativity rates, which are indicative of a deep remission, are particularly promising in the treated patient population. This encouraging activity, along with a manageable safety profile, support the continued evaluation of this novel triplet in this setting."

PIVEKIMAB SUNIRINE, A CD123-TARGETING ANTIBODY-DRUG CONJUGATE, IN COMBINATION WITH AZACITIDINE AND VENETOCLAX IN PATIENTS WITH NEWLY DIAGNOSED ACUTE MYELOID LEUKEMIA
Lead Author: Navel Daver, MD
Poster Session: 616 (Acute Myeloid Leukemias: Investigational Therapies, Excluding Transplantation and Cellular Immunotherapies: Poster II)
Date and Time: Sunday, December 10, 2023, 6:00-8:00 p.m. PT / 9:00-11:00 p.m. ET
Publication Number: 2906

In the open-label, multicenter, Phase 1b/2 study of pivekimab in combination with azacitidine and venetoclax in patients with ND CD123-positive AML, patients received the recommended Phase 2 dose of pivekimab at 0.045 mg/kg on day 7, azacitidine at 75 mg/m2 daily on days 1-7, and venetoclax at up to 400 mg for at least 14 days or up to 28 days, based on cohort assignment, in a 28-day cycle. The primary endpoints are complete remission (CR) rate, composite CR rate (CCR [CR+CRh+CRp+CRi]), minimal residual disease (MRD) negativity rate, and duration of remission. Key secondary endpoints are safety, pharmacokinetics, and immunogenicity.

Key findings for 50 ND patients (n=25 per cohort) as of September 29, 2023 (data cut-off) include:

Anti-Leukemia Activity

In the overall population, CCR rate was 68% (34/50), CR rate was 54% (27/50), and MRD negativity rate among evaluable patients achieving CCR was 76% (22/29). MRD was assessed centrally by flow cytometry with <0.1% considered negative. Response rates and MRD negativity were numerically comparable between cohorts 1 and 2, despite differences in the venetoclax schedule.
In a post hoc subset analysis of patients unfit for intensive chemotherapy (i.e. patients >75 years of age, and/or with pre-specified comorbidities) (n=23), CCR rate was 78% (18/23), CR rate was 61% (14/23), and MRD negativity rate was 79% (11/14).
In patients known to be TP53wt (n=25), CCR rate was 88% (22/25), CR rate was 84% (21/25), and MRD negativity rate was 80% (16/20). CCR and MRD negativity rates, respectively, were high across other major molecular subsets, including:
FLT3 (ITD or TKD): 100% (6/6) and 100% (6/6)
IDH1 mutant: 100% (4/4) and 67% (2/3)
IDH2 mutant: 100% (6/6) and 83% (5/6)
NPM1 mutant: 100% (8/8) and 86% (6/7)
K/NRAS mutant: 50% (3/6) and 67% (2/3)
TP53 mutant: 50% (7/14) and 50% (3/6)
Among all MRD negative patients, the median time to MRD negativity was 1.87 months (range: 0.79-5.16 months).
Although follow-up duration was short (median 5.2 months), landmark overall survival estimate at 6 months is 86%.
The study is continuing to enroll newly diagnosed unfit AML patients.
Safety

The triplet displayed a manageable safety profile; no new safety signals were observed compared to previously reported data.
The most common non-hematologic treatment-emergent adverse events (TEAEs) (all grades [grade 3+]) seen in ≥20% of all patients were constipation (48% [2%]), peripheral edema (44% [4%]), diarrhea (40% [2%]), hypophosphatemia (34% [2%]), nausea (32% [4%]), hypokalemia (28% [4%]), fatigue (24% [6%]), hypotension (24% [2%]), and pyrexia (24% [0%]). In the overall population:
Rates of cytopenias were similar to those observed with azacitidine and venetoclax, with a median neutrophil recovery to ≥500/µL and platelet recovery to ≥50,000/µL by day 34 and day 22, respectively.
No veno-occlusive disease, capillary leak syndrome, or sinusoidal obstruction syndrome were observed.
Infusion-related reactions (IRRs) occurred in 16% of patients (0 grade 3+ IRRs).
Discontinuations due to an adverse event (AE) were 4% (2 patients).
30-day mortality was 0%.
60-day mortality was 4% (2 patients; due to pneumonia and early disease progression).
"Building upon our initial findings in frontline AML presented last year, these data show broad and consistent response rates in a larger study population and across major molecular subsets of interest, including those patients with biological mutations making them high-risk," said Michael Vasconcelles, MD, ImmunoGen’s Executive Vice President, Research, Development, and Medical Affairs. "We are pleased with the low early mortality and manageable safety profile observed, in particular the lack of prolonged cytopenias. We look forward to continuing to expand our cohort of newly diagnosed unfit patients to inform the development path for pivekimab in AML."

ABOUT PIVEKIMAB SUNIRINE
Pivekimab sunirine is a CD123-targeting ADC in clinical development for hematological malignancies, including blastic plasmacytoid dendritic cell neoplasm (BPDCN), acute myeloid leukemia (AML), and other CD123+ hematologic malignancies. Pivekimab is currently being evaluated as monotherapy for patients with BPDCN and in combination with azacitidine (Vidaza) and venetoclax (Venclexta) for patients with untreated and relapsed/refractory AML. Pivekimab uses one of ImmunoGen’s novel indolinobenzodiazepine (IGN) payloads, which alkylate DNA and cause single-strand breaks without crosslinking. IGNs are designed to have high potency against tumor cells, while demonstrating less toxicity to normal marrow progenitors than other DNA-targeting payloads. The European Medicines Agency (EMA) granted orphan drug designation to pivekimab for the treatment of BPDCN in June 2020. Pivekimab also holds this designation in the US. In October 2020, the FDA granted pivekimab Breakthrough Therapy designation in relapsed/refractory BPDCN.

ABOUT ACUTE MYELOID LEUKEMIA (AML)
AML is a cancer of the bone marrow cells that produce white blood cells. It causes the marrow to increasingly generate abnormal, immature white blood cells (blasts) that do not mature into effective infection-fighting cells. The blasts quickly fill the bone marrow, impacting the production of normal platelets and red blood cells. The resulting deficiencies in normal blood cells leave the patient vulnerable to infections, bleeding problems, and anemia. It is estimated that, in the US alone, more than 20,000 people will be diagnosed with AML and more than 11,000 will die from the disease this year.

ABOUT CD123
CD123, the interleukin-3 alpha chain, is expressed on multiple myeloid and lymphoid cancers including AML, BPDCN, ALL, chronic myeloid leukemia, and myeloproliferative neoplasms. With limited expression on normal hematopoietic cells, rapid internalization, and expression on AML leukemia stem cells, CD123 is a clinically validated therapeutic target.

On December 10, 2023 Karyopharm Therapeutics Inc. (Nasdaq: KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies, reported long-term follow up of treatment-naïve patients with myelofibrosis (MF) who participated in the Phase 1 portion of its study evaluating once-weekly selinexor in combination with ruxolitinib (NCT04562389) (Press release, Karyopharm, DEC 10, 2023, View Source,-with-no-SVR-or-TSS-Progressions-Observed-As-of-the-Data-C [SID1234638381]). The data, featured in an oral presentation at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition (ASH 2023), show patients treated with 60mg selinexor, and who achieved ≥35% reduction in spleen volume (SVR35) at week 24, continued to remain in radiographic response. In addition, all patients who achieved TSS50 at Week 24 remained in response as of the data cut-off.

The data included in the oral presentation for ASH (Free ASH Whitepaper) 2023 were based on the Phase 1 portion of the Phase 1/3 study evaluating the safety and efficacy of once-weekly selinexor in combination with ruxolitinib in patients with treatment-naïve MF (NCT04562389). As of August 1, 2023, 24 patients had been assigned to either selinexor 40mg (N= 10) or 60mg (N=14), in combination with ruxolitinib. The maximum duration of follow-up was 78 weeks with a median duration of 32 weeks for SVR35 durability, and a maximum duration of follow-up was 64 weeks with a median duration of 51 weeks for TSS50 durability.

An exploratory biomarker analysis showed a reduction of variant allele frequency (VAF) at week 24 for all three MF driver genes (CALR, MPL, and JAK2) and rapid and sustained reduction of pro-inflammatory cytokine production. Early cytokine reduction at Week 4 was associated with spleen volume reduction (SVR) at Week 24 and was sustained until the end of treatment. The clinical efficacy associated with biomarkers impacting MF biological hallmarks may suggest disease modification.

"The growing body of data from this study suggests that selinexor in combination with ruxolitinib may provide spleen reduction, symptom improvement, long-term durability and disease modification, expanding the benefit this combination may provide to patients with treatment-naïve myelofibrosis, " said Reshma Rangwala, MD, PhD, Chief Medical Officer of Karyopharm. "We’re excited about the potential to change treatment paradigms for these patients – and expand the number of patients who benefit from first-line therapy."

The safety profile was consistent with previous data cuts with no new safety signals observed as of Aug 1st.

"The current standard of care is not associated with consistent molecular or pathologic responses," said Dr. Sri Tantravahi, University of Utah. "The long-term findings are very exciting as they underscore the potential for durable, clinically relevant responses and modification of disease course. The wait for new options has been long and difficult for the myelofibrosis community, and we welcome this important research to help advance the understanding of XPO1 and JAK inhibitor combinations as a meaningful treatment option for patients."

"We are encouraged by the attention MPNs (Myeloproliferative Neoplasms) are getting in recent years from companies like Karyopharm," said Kapila Viges, Chief Executive Officer of MPN Research Foundation. "With patients waiting for more answers to these chronic yet serious blood cancers, we look forward to the data readouts at ASH (Free ASH Whitepaper) this year. Efforts to develop better therapies and now combinations of therapies bring hope to the myelofibrosis community and open the potential for more options in the treatment paradigm. For patients, options matter."

"The rapid and durable responses observed in the Phase 2 TELLOMAK trial which enrolled heavily pretreated patients, confirms that treatment with lacutamab achieves clinically meaningful outcomes for patients with Sézary Syndrome after at least two prior systemic therapies," commented Dr. Sonia Quaratino, Chief Medical Officer of Innate Pharma. "Enrollment to TELLOMAK study is completed and long-term follow-up will provide more mature data on the key study endpoints in due course."

Prof. Pierluigi Porcu, Director, Division of Hematologic Malignancies and Hematopoietic Stem Cell Transplantation, Sidney Kimmel Cancer Center, Jefferson Health, Philadelphia, and Principal Investigator in the TELLOMAK study, added: "Sézary Syndrome patients treated with more than two prior systemic therapies including mogamulizumab, represent a high unmet medical need population with poor quality of life. It is promising to see lacutamab achieving remarkable efficacy along with favorable safety in this heavily pre-treated population. We thank the investigators, clinical research coordinators, patients and caregivers involved in the TELLOMAK program."

About Lacutamab

Lacutamab is a first-in-class anti-KIR3DL2 humanized cytotoxicity-inducing antibody that is currently in clinical trials for treatment of cutaneous T-cell lymphoma (CTCL), an orphan disease, and peripheral T cell lymphoma (PTCL). Rare cutaneous lymphomas of T lymphocytes have a poor prognosis with few efficacious and safe therapeutic options at advanced stages.

KIR3DL2 is an inhibitory receptor of the KIR family, expressed by approximately 65% of patients across all CTCL subtypes and expressed by up 90% of patients with certain aggressive CTCL subtypes, in particular, Sézary syndrome. It is expressed by up to 50% of patients with mycosis fungoides and peripheral T-cell lymphoma (PTCL). It has a restricted expression on normal tissues.

Lacutamab is granted European Medicines Agency (EMA) PRIME designation and US Food and Drug Administration (FDA) granted Fast Track designation for the treatment of patients with relapsed or refractory Sézary syndrome who have received at least two prior systemic therapies. Lacutamab is granted orphan drug status in the European Union and in the United States for the treatment of CTCL.

About TELLOMAK

TELLOMAK (NCT03902184) is a global, open-label, multi-cohort Phase 2 clinical trial recruiting patients with Sézary syndrome and mycosis fungoides (MF) in the United States and Europe. Specifically:

Cohort 1: lacutamab being evaluated as a single agent in approximately 60 patients with Sézary syndrome who have received at least two prior systemic therapies, including mogamulizumab. The Sézary syndrome cohort of the study could enable the registration of lacutamab in this indication.
Cohort 2: lacutamab being evaluated as a single agent in patients with MF that express KIR3DL2, as determined at baseline with a Simon 2-stage design.
Cohort 3: lacutamab being evaluated as a single agent in patients with MF that do not express KIR3DL2, as determined at baseline, with a Simon-2 stage design.
All comers: lacutamab being evaluated as a single agent in patients with both KIR3DL2 expressing and non-expressing MF to explore the correlation between the level of KIR3DL2 expression and treatment outcomes utilizing a formalin-fixed paraffin embedded (FFPE) assay under development as a companion diagnostic.
The trial is now fully enrolled. The primary endpoint of the trial is objective global response rate. Key secondary endpoints are progression-free survival, duration of response, overall survival, quality of life, pharmacokinetics and immunogenicity and adverse events.

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.

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.
