JEFFERSON CITY, Mo., March 21, 2024 (GLOBE NEWSWIRE) -- As vaccine uptake continues to decrease, measles cases or outbreaks have emerged in several states, including Missouri earlier this year. Nationally, the total number of measles cases has already reached the level that occurred during the entire year of 2023. With cases reported across the country, the Missouri Department of Health & Senior Services (DHSS) recommends parents and guardians check their child’s vaccination records to make sure they have received the measles, mumps and rubella (MMR) vaccine. This vaccine has been used in the United States since the 1970s and is a safe and effective way to protect children from measles. To be fully immunized, children are recommended to receive two doses of the MMR vaccine, with the first dose between ages 12-15 months and the second dose between ages 4-6 years old. Infants as young as 6 months can receive the first dose if traveling to areas where the measles infection rate is high. Families should consult their health care provider to discuss appropriate vaccine options for their children. Herd immunity, achieved through a measles vaccination rate of 95% or more, is crucial for preventing disease outbreaks in the community and protecting vulnerable populations who cannot receive vaccines. “Achieving this level of vaccination creates a barrier that limits the spread of infectious disease within a community, safeguarding those who are unable to be vaccinated due to their age or compromised immune systems,” said Dr. George Turabelidze, state epidemiologist with DHSS. Statewide, the MMR vaccination rate among kindergarteners has dropped steadily from 95.4% in the 2016-2017 school year to 90.5% at the start of the 2023-2024 school year, according to preliminary data reported by Missouri school districts. Religious (non-medical) exemptions have simultaneously increased from 1.9% to 3.5%. The measles vaccine, given as part of the MMR (measles, mumps and rubella) vaccine, is extremely effective, giving those vaccinated with just one dose 93% protection against measles infection. Both doses of the vaccine provide individuals with a 97% protection rate throughout their lifetime. Measles is a highly contagious and serious disease, especially serious for children under age five and those who are immunocompromised. Common symptoms include a rash that starts as flat red spots on the head and spreads to other parts of the body, high fever, cough, runny nose, red and watery eyes, and tiny white spots inside the mouth. But in some instances, individuals with measles will develop brain infection, which can lead to brain damage, and for some, the disease is fatal even with the best care. The virus spreads through coughing and sneezing and can live for up to two hours in an airspace after an infected person leaves an area. A person can spread measles without knowing they are infected. If not treated, complications can grow in severity. Most health insurance plans cover vaccines, but individuals should check with their insurance provider to verify coverage. For those without insurance, the Vaccines for Children Program, funded by the Centers for Disease Control and Prevention (CDC), provides free vaccines to children who qualify. Additionally, most local public health agencies throughout the state of Missouri offer vaccinations at affordable rates.

NEW YORK--( BUSINESS WIRE )--Pfizer Inc. (NYSE: PFE) today announced that the European Commission (EC) has approved TALZENNA ® (talazoparib), an oral poly ADP-ribose polymerase (PARP) inhibitor, in combination with XTANDI ® (enzalutamide), for the treatment of adult patients with metastatic castration-resistant prostate cancer (mCRPC) in whom chemotherapy is not clinically indicated. With this approval, TALZENNA is now the first and only PARP inhibitor licensed in the European Union for use with XTANDI for patients with mCRPC, with or without gene mutations. “ New treatment options are needed to increase the proportion of patients with metastatic castration-resistant prostate cancer who can benefit from current anticancer medicines that keep the disease under control for longer,” said Robert Jones, MBChB, PhD, Professor of Clinical Cancer Research, University of Glasgow. “ The European Commission’s approval of talazoparib in combination with enzalutamide offers a meaningful advancement for the treatment of patients with metastatic castration-resistant prostate cancer, the most advanced and aggressive stage of the disease.” “ After years of fighting prostate cancer, it can be devastating for a patient to learn that their cancer has stopped responding to testosterone-lowering treatments. At this stage of the disease, the prognosis is generally poor,” said Erik Briers, MS, PhD, Vice Chairman, Europa UOMO, a European advocacy movement for people with prostate cancer. “ Patients urgently need new treatment options and TALZENNA in combination with XTANDI can bring new hope to these patients.” This approval by the European Commission of TALZENNA in combination with XTANDI for the mCRPC indication is valid in all 27 EU member states plus Iceland, Liechtenstein, and Norway. The approval is based on data from the Phase 3 TALAPRO-2 trial, a multicenter, randomized, double-blind, placebo-controlled study, evaluating two mCRPC patient cohorts: Cohort 1 (all-comers [n=805]) and Cohort 2 (those with HRR gene mutations [HRRm; n=399]). The results from TALAPRO-2 Cohort 1, which were published in The Lancet , showed that treatment with TALZENNA plus XTANDI reduced the risk of disease progression or death by 37% versus placebo plus XTANDI (Hazard Ratio [HR]: 0.63; 95% Confidence Interval [CI], 0.51–0.78; P< 0.0001), meeting the study’s primary endpoint of improving radiographic progression-free survival (rPFS). At the time of the analysis, the median rPFS for those treated with TALZENNA plus XTANDI had not yet been reached versus 21.9 months for those treated with placebo plus XTANDI. Median rPFS is defined as the timepoint in which 50% of patients in each treatment arms have progressed. A trend in overall survival (OS), a key secondary endpoint, favoring TALZENNA plus XTANDI was also observed, though these data are immature. The safety of TALZENNA plus XTANDI in the TALAPRO-2 trial was generally consistent with the known safety profile of each medicine. “ Today’s approval of TALZENNA in combination with XTANDI represents an important advancement for men living with prostate cancer in Europe,” said Chris Boshoff, M.D., Ph.D., Chief Oncology Officer, Executive Vice President, Pfizer. “ The results from the pivotal TALAPRO-2 trial showed that this combination offers an effective treatment that addresses disease progression in patients with or without any specific gene mutation.” TALZENNA in combination with XTANDI was approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with HRR gene-mutated mCRPC in June 2023. Pfizer has also shared the TALAPRO-2 data with other regulatory agencies to support regulatory filings. About Metastatic Castration-Resistant Prostate Cancer Metastatic castration-resistant prostate cancer (mCRPC) is a cancer that has spread beyond the prostate gland and has progressed despite medical or surgical treatment to lower testosterone. There were ~1.4 million new cases of prostate cancer reported worldwide in 2020, of which ~470,000 new cases were in Europe. 1 Approximately 10%–20% of prostate cancer patients develop mCRPC within 5−7 years of diagnosis. 2 Between 1.2%–2.1% of all prostate cancer cases globally are mCRPC. 3 About TALAPRO-2 The Phase 3 TALAPRO-2 trial is a two-part, two-cohort, multicenter, randomized, double-blind, placebo-controlled study that enrolled 1,106 patients with mCRPC (with no systemic treatments initiated after documentation of mCRPC) at sites in the U.S., Canada, Europe, South America, and the Asia-Pacific region. The study included two patient cohorts: all-comers (n=805) and those with and without gene mutations (HRRm; n=399). Patients on androgen deprivation therapy (ADT) or who had bilateral orchiectomy in the trial were randomized to receive TALZENNA 0.5 mg/day plus XTANDI 160mg/day, or placebo plus XTANDI 160 mg/day. The primary endpoint of the trial is radiographic progression-free survival (rPFS), defined as the time from the date of randomization to first objective evidence of radiographic progression by blinded independent review, or death, whichever occurs first, in both Cohort 1 (all-comers) and Cohort 2 (those with HRRm). Secondary endpoints include overall survival (OS), objective response rate, duration of response, and PSA response. For more information on the TALAPRO-2 trial ( NCT03395197 ), go to www.clinicaltrials.gov . About TALZENNA ® (talazoparib) TALZENNA (talazoparib) is an oral inhibitor of poly ADP-ribose polymerase (PARP), which plays a role in DNA damage repair. Preclinical studies have demonstrated that TALZENNA blocks PARP enzyme activity and traps PARP at the site of DNA damage, leading to decreased cancer cell growth and cancer cell death. TALZENNA is approved in over 70 countries, including the U.S and the EU, as a once-daily monotherapy for the treatment of adult patients with deleterious or suspected deleterious germline breast cancer susceptibility gene (BRCA)-mutated (gBRCAm) human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer. In the U.S., TALZENNA is approved in combination with XTANDI ® (enzalutamide) for the treatment of adult patients with homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). In the EU, TALZENNA is now approved in combination with enzalutamide for the treatment of adult patients with mCRPC in whom chemotherapy is not clinically indicated. TALZENNA ® (talazoparib) Indication in the U.S. TALZENNA is a poly (ADP-ribose) polymerase (PARP) inhibitor indicated for: Breast Cancer: As a single agent, for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) HER2-negative locally advanced or metastatic breast cancer. Select patients for therapy based on an FDA-approved companion diagnostic for TALZENNA. HRR Gene-mutated mCRPC: In combination with enzalutamide for the treatment of adult patients with homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). TALZENNA ® (talazoparib) Important Safety Information WARNINGS and PRECAUTIONS Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML) , including cases with a fatal outcome, has been reported in patients who received TALZENNA. Overall, MDS/AML has been reported in 0.4% (3 out of 788) of solid tumor patients treated with TALZENNA as a single agent in clinical studies. In TALAPRO-2, MDS/AML occurred in 2 out of 511 (0.4%) patients treated with TALZENNA and enzalutamide and in 0 out of 517 (0%) patients treated with placebo and enzalutamide. The durations of TALZENNA treatment in these five patients prior to developing MDS/AML were 0.3, 1, 2, 3, and 5 years, respectively. Most of these patients had received previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy. Do not start TALZENNA until patients have adequately recovered from hematological toxicity caused by previous chemotherapy. Monitor blood counts monthly during treatment with TALZENNA. For prolonged hematological toxicities, interrupt TALZENNA and monitor blood counts weekly until recovery. If counts do not recover within 4 weeks, refer the patient to a hematologist for further investigations including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue TALZENNA. Myelosuppression consisting of anemia, neutropenia, and/or thrombocytopenia have been reported in patients treated with TALZENNA. In TALAPRO-2, Grade ≥3 anemia, neutropenia, and thrombocytopenia were reported, respectively, in 45%, 18%, and 8% of patients receiving TALZENNA and enzalutamide. Overall, 39% of patients (199/511) required a red blood cell transfusion, including 22% (111/511) who required multiple transfusions. Discontinuation due to anemia, neutropenia, and thrombocytopenia occurred, respectively, in 7%, 3%, and 0.4% of patients. Withhold TALZENNA until patients have adequately recovered from hematological toxicity caused by previous therapy. Monitor blood counts monthly during treatment with TALZENNA. If hematological toxicities do not resolve within 28 days, discontinue TALZENNA and refer the patient to a hematologist for further investigations including bone marrow analysis and blood sample for cytogenetics. Embryo-Fetal Toxicity TALZENNA can cause fetal harm when administered to pregnant women. Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment with TALZENNA and for 4 months after receiving the last dose. ADVERSE REACTIONS Serious adverse reactions reported in >2% of patients included anemia (9%) and fracture (3%). Fatal adverse reactions occurred in 1.5% of patients, including pneumonia, COVID infection, and sepsis (1 patient each). The most common adverse reactions (≥ 10%, all Grades), including laboratory abnormalities, for patients in the TALAPRO-2 study who received TALZENNA in combination with enzalutamide vs patients receiving placebo with enzalutamide were hemoglobin decreased (79% vs 34%), neutrophils decreased (60% vs 18%), lymphocytes decreased (58% vs 36%), fatigue (49% vs 40%), platelets decreased (45% vs 8%), calcium decreased (25% vs 11%), nausea (21% vs 17%), decreased appetite (20% vs 14%), sodium decreased (22% vs 20%), phosphate decreased (17% vs 13%), fractures (14% vs 10%), magnesium decreased (14% vs 12%), dizziness (13% vs 9%), bilirubin increased (11% vs 7%), potassium decreased (11% vs 7%), and dysgeusia (10% vs 4.5%). Clinically relevant adverse reactions in <10% of patients who received TALZENNA with enzalutamide included abdominal pain (9%), vomiting (9%), alopecia (7%), dyspepsia (4%), venous thromboembolism (3%) and stomatitis (2%). Based on animal studies, TALZENNA may impair fertility in males of reproductive potential. DRUG INTERACTIONS Coadministration with P-gp inhibitors The effect of coadministration of P-gp inhibitors on talazoparib exposure when TALZENNA is taken in combination with enzalutamide has not been studied. Monitor patients for increased adverse reactions and modify the dosage as recommended for adverse reactions when TALZENNA is coadministered with a P-gp inhibitor. Coadministration with BCRP inhibitors Monitor patients for increased adverse reactions and modify the dosage as recommended for adverse reactions when TALZENNA is coadministered with a BCRP inhibitor. Coadministration of TALZENNA with BCRP inhibitors may increase talazoparib exposure, which may increase the risk of adverse reactions. USE IN SPECIFIC POPULATIONS Renal Impairment The recommended dosage of TALZENNA for patients with moderate renal impairment (CLcr 30 - 59 mL/min) is 0.35 mg taken orally once daily in combination with enzalutamide. The recommended dosage of TALZENNA for patients with severe renal impairment (CLcr 15 - 29 mL/min) is 0.25 mg taken orally once daily in combination with enzalutamide. No dose adjustment is required for patients with mild renal impairment. TALZENNA has not been studied in patients requiring hemodialysis. Please see full U.S. Prescribing Information and Patient Information for TALZENNA ® (talazoparib) at www.TALZENNA.com . About XTANDI ® (enzalutamide) and Important Safety Information XTANDI ® (enzalutamide) is an androgen receptor signaling inhibitor. XTANDI is a standard of care and has received regulatory approvals in one or more countries around the world for use in men with metastatic castration-sensitive prostate cancer (mCSPC; also known as metastatic hormone-sensitive prostate cancer or mHSPC), metastatic castration-resistant prostate cancer (mCRPC), non-metastatic castration-resistant prostate cancer (nmCRPC) and nonmetastatic castration-sensitive prostate cancer (nmCSPC) with biochemical recurrence at high risk for metastasis (high-risk BCR). XTANDI is currently approved for one or more of these indications in more than 90 countries, including in the U.S., EU, and Japan. Over one million patients have been treated with XTANDI globally. 4 Warnings and Precautions Seizure occurred in 0.6% of patients receiving XTANDI in eight randomized clinical trials. In a study of patients with predisposing factors for seizure, 2.2% of XTANDI-treated patients experienced a seizure. It is unknown whether anti-epileptic medications will prevent seizures with XTANDI. Patients in the study had one or more of the following predisposing factors: use of medications that may lower the seizure threshold, history of traumatic brain or head injury, history of cerebrovascular accident or transient ischemic attack, and Alzheimer’s disease, meningioma, or leptomeningeal disease from prostate cancer, unexplained loss of consciousness within the last 12 months, history of seizure, presence of a space occupying lesion of the brain, history of arteriovenous malformation, or history of brain infection. Advise patients of the risk of developing a seizure while taking XTANDI and of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others. Permanently discontinue XTANDI in patients who develop a seizure during treatment. Posterior Reversible Encephalopathy Syndrome (PRES) There have been reports of PRES in patients receiving XTANDI. PRES is a neurological disorder that can present with rapidly evolving symptoms including seizure, headache, lethargy, confusion, blindness, and other visual and neurological disturbances, with or without associated hypertension. A diagnosis of PRES requires confirmation by brain imaging, preferably MRI. Discontinue XTANDI in patients who develop PRES. Hypersensitivity reactions, including edema of the face (0.5%), tongue (0.1%), or lip (0.1%) have been observed with XTANDI in eight randomized clinical trials. Pharyngeal edema has been reported in post-marketing cases. Advise patients who experience any symptoms of hypersensitivity to temporarily discontinue XTANDI and promptly seek medical care. Permanently discontinue XTANDI for serious hypersensitivity reactions. Ischemic Heart Disease In the combined data of five randomized, placebo-controlled clinical studies, ischemic heart disease occurred more commonly in patients on the XTANDI arm compared to patients on the placebo arm (3.5% vs 2%). Grade 3-4 ischemic events occurred in 1.8% of patients on XTANDI versus 1.1% on placebo. Ischemic events led to death in 0.4% of patients on XTANDI compared to 0.1% on placebo. Monitor for signs and symptoms of ischemic heart disease. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Discontinue XTANDI for Grade 3-4 ischemic heart disease. Falls and Fractures occurred in patients receiving XTANDI. Evaluate patients for fracture and fall risk. Monitor and manage patients at risk for fractures according to established treatment guidelines and consider use of bone-targeted agents. In the combined data of five randomized, placebo-controlled clinical studies, falls occurred in 12% of patients treated with XTANDI compared to 6% of patients treated with placebo. Fractures occurred in 13% of patients treated with XTANDI and in 6% of patients treated with placebo. Embryo-Fetal Toxicity The safety and efficacy of XTANDI have not been established in females. XTANDI can cause fetal harm and loss of pregnancy when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment with XTANDI and for 3 months after the last dose of XTANDI. Adverse Reactions (ARs) In the data from the five randomized placebo-controlled trials, the most common ARs (≥ 10%) that occurred more frequently (≥ 2% over placebo) in XTANDI-treated patients were musculoskeletal pain, fatigue, hot flush, constipation, decreased appetite, diarrhea, hypertension, hemorrhage, fall, fracture, and headache. In the bicalutamide-controlled study, the most common ARs (≥ 10%) reported in XTANDI-treated patients were asthenia/fatigue, back pain, musculoskeletal pain, hot flush, hypertension, nausea, constipation, diarrhea, upper respiratory tract infection, and weight loss. In AFFIRM, the placebo-controlled study of metastatic CRPC (mCRPC) patients who previously received docetaxel, Grade 3 and higher ARs were reported among 47% of XTANDI-treated patients. Discontinuations due to ARs were reported for 16% of XTANDI-treated patients. In PREVAIL, the placebo-controlled study of chemotherapy-naive mCRPC patients, Grade 3-4 ARs were reported in 44% of XTANDI patients and 37% of placebo patients. Discontinuations due to ARs were reported for 6% of XTANDI-treated patients. In TERRAIN, the bicalutamide-controlled study of chemotherapy-naive mCRPC patients, Grade 3-4 ARs were reported in 39% of XTANDI patients and 38% of bicalutamide patients. Discontinuations with an AR as the primary reason were reported for 8% of XTANDI patients and 6% of bicalutamide patients. In PROSPER, the placebo-controlled study of nonmetastatic CRPC (nmCRPC) patients, Grade 3 or higher ARs were reported in 31% of XTANDI patients and 23% of placebo patients. Discontinuations with an AR as the primary reason were reported for 9% of XTANDI patients and 6% of placebo patients. In ARCHES, the placebo-controlled study of metastatic CSPC (mCSPC) patients, Grade 3 or higher ARs were reported in 24% of XTANDI-treated patients. Permanent discontinuation due to ARs as the primary reason was reported in 5% of XTANDI patients and 4% of placebo patients. In EMBARK, the placebo-controlled study of nonmetastatic CSPC (nmCSPC) with high-risk biochemical recurrence (BCR) patients, Grade 3 or higher adverse reactions during the total duration of treatment were reported in 46% of patients treated with XTANDI plus leuprolide, 50% of patients receiving XTANDI as a single agent, and 43% of patients receiving placebo plus leuprolide. Permanent treatment discontinuation due to adverse reactions during the total duration of treatment as the primary reason was reported in 21% of patients treated with XTANDI plus leuprolide, 18% of patients receiving XTANDI as a single agent, and 10% of patients receiving placebo plus leuprolide. Lab Abnormalities: Lab abnormalities that occurred in ≥ 5% of patients, and more frequently (> 2%) in the XTANDI arm compared to placebo in the pooled, randomized, placebo-controlled studies are hemoglobin decrease, neutrophil count decreased, white blood cell decreased, hyperglycemia, hypermagnesemia, hyponatremia, hyperphosphatemia, and hypercalcemia. Hypertension: In the combined data from five randomized placebo-controlled clinical trials, hypertension was reported in 14.2% of XTANDI patients and 7.4% of placebo patients. Hypertension led to study discontinuation in < 1% of patients in each arm. Drug Interactions Effect of Other Drugs on XTANDI Avoid coadministration with strong CYP2C8 inhibitors. If coadministration cannot be avoided, reduce the dosage of XTANDI. Avoid coadministration with strong CYP3A4 inducers. If coadministration cannot be avoided, increase the dosage of XTANDI. Effect of XTANDI on Other Drugs Avoid coadministration with certain CYP3A4, CYP2C9, and CYP2C19 substrates for which minimal decrease in concentration may lead to therapeutic failure of the substrate. If coadministration cannot be avoided, increase the dosage of these substrates in accordance with their Prescribing Information. In cases where active metabolites are formed, there may be increased exposure to the active metabolites. Please see Full Prescribing Information for additional safety information.

Longer-term data from pivotal studies of fixed-duration Columvi and Lunsumio continue to show durable responses in people with heavily pre-treated lymphomas New data reinforce the potential of combination regimens in earlier treatment settings and add to the robust body of evidence supporting ongoing Phase III studies SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today 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) Annual Meeting & Exposition, December 9-12, 2023. 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 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 pro 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 pro 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 pro 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.

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.
