First new treatment regimen in more than 20 years to significantly improve outcomes in people with this fast-growing type of lymphoma Application is based on pivotal data from the phase III POLARIX study showing Polivy plus R-CHP significantly reduced the risk of disease progression, relapse or death with comparable safety versus the standard of care, R-CHOPVarious combination studies with Polivy and the company's CD20xCD3 bispecifics in diffuse large B-cell lymphoma are ongoing Basel, 16 August 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) for Polivy® (polatuzumab vedotin-piiq) in combination with Rituxan® (rituximab) plus cyclophosphamide, doxorubicin and prednisone (R-CHP) for the treatment of people with previously untreated diffuse large B-cell lymphoma (DLBCL). The FDA is expected to make a decision on approval by 2 April 2023.“The POLARIX study results suggest that Polivy plus R-CHP could transform the treatment of this aggressive malignancy, and we are working with the FDA to bring this combination to newly diagnosed DLBCL patients as soon as possible,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “We hope it will become the new standard of care for the first-line treatment of DLBCL, potentially reducing the need for subsequent treatments and limiting patient burden.”DLBCL is an aggressive blood cancer. Although DLBCL often responds to initial treatment, it is not cured with the current standard of care in four out of 10 people. Most relapses occur within two years of starting treatment and the majority of those who require subsequent lines of therapy have poor outcomes.The sBLA is based on results from the pivotal phase III POLARIX trial, which is the first in two decades to show a clinically meaningful improvement in progression-free survival (PFS) compared to the current standard of care Rituxan plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). The risk of disease progression, relapse or death was reduced by 27% with Polivy plus R-CHP compared with R-CHOP after a median follow-up of 28.2 months (hazard ratio [HR] 0.73; 95% confidence interval [CI]: 0.57–0.95; p<0.02). Safety outcomes were consistent with those seen in previous clinical trials, and the safety profile was comparable for Polivy plus R-CHP versus R-CHOP, including rates of Grade 3-4 adverse events (AEs; 57.7% versus 57.5%), serious AEs (34.0% versus 30.6%), Grade 5 AEs (3.0% versus 2.3%), and AEs leading to dose reduction (9.2% versus 13.0%).Based on pivotal data from the POLARIX study, the European Commission approved Polivy in combination with R-CHP in May 2022 for the treatment of adult patients with previously untreated DLBCL. Polivy is currently approved as a readily available, fixed-duration treatment option for relapsed or refractory (R/R) DLBCL in combination with bendamustine and Mabthera/Rituxan in more than 70 countries worldwide, including in the EU and in the United States.Roche continues to explore areas of unmet need where Polivy has the potential to deliver additional benefit, including in ongoing studies investigating combinations of Polivy with the company’s CD20xCD3 T-cell engaging bispecific antibodies Lunsumio® (mosunetuzumab) and glofitamab, and with Rituxan in combination with gemcitabine and oxaliplatin in the phase III POLARGO study.About the POLARIX studyPOLARIX [NCT03274492] is an international phase III, randomised, double-blind, placebo- controlled study evaluating the efficacy, safety and pharmacokinetics of Polivy® (polatuzumab vedotin-piiq) plus Rituxan® (rituximab), cyclophosphamide, doxorubicin, and prednisone (R-CHP) versus rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in people with previously untreated diffuse large B-cell lymphoma. Eight-hundred and seventy-nine patients were randomised 1:1 to receive either Polivy plus R- CHP plus a vincristine placebo for six cycles, followed by rituximab for two cycles; or R-CHOP plus a Polivy placebo for six cycles, followed by two cycles of rituximab. The primary outcome measure is progression-free survival (PFS) as assessed by the investigator using the Lugano Response Criteria for malignant lymphoma. POLARIX is being conducted in collaboration with The Lymphoma Study Association (LYSA) and The Lymphoma Academic Research Organisation (LYSARC). Other clinical investigators from around the world also participated in the trial.About diffuse large B-cell lymphoma (DLBCL)DLBCL is the most common form of non-Hodgkin lymphoma (NHL), accounting for about one in three cases of NHL.[1] DLBCL is an aggressive (fast-growing) type of NHL. [1] While it is generally responsive to treatment in the frontline, as many as 40% of people will relapse or have refractory disease, at which time salvage therapy options are limited and survival is short.[2,3] Approximately 150,000 people worldwide are estimated to be diagnosed with DLBCL each year.[4]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 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 minimise the effects on normal cells. Polivy is being developed by Roche using Seagen ADC technology and is currently being investigated for the treatment of several types of NHL. Polivy is currently marketed in the EU for the treatment of relapsed or refractory diffuse large B-cell lymphoma.About Roche in haematologyRoche has been developing medicines for people with malignant and non-malignant blood diseases for more than 20 years; our experience and knowledge in this therapeutic area runs deep.

First new treatment option in more than 20 years to show a clinically meaningful improvement in progression-free survival is approved for people with previously untreated diffuse large B-cell lymphoma (DLBCL)Approval is based on pivotal data from the phase III POLARIX study, where Polivy plus R-CHP significantly improved progression-free survival with comparable safety versus the standard of care, R-CHOPFirst-line treatment with Polivy plus R-CHP has the potential to reduce the burden on patients and healthcare systems, associated with disease progression1 Basel, 25 May 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the European Commission (EC) has granted approval of Polivy® (polatuzumab vedotin) in combination with MabThera®(rituximab) plus cyclophosphamide, doxorubicin, and prednisone (R-CHP) for the treatment of adult patients with previously untreated diffuse large B-cell lymphoma (DLBCL).DLBCL is an aggressive blood cancer and the most common form of non-Hodgkin lymphoma.2 Each year in Europe, it is estimated that 40,000 people are diagnosed with DLBCL.3 While many patients are responsive to initial treatment, four out of ten are not cured with the current standard of care, and the majority of people who require subsequent lines of therapy have poor outcomes.4,5 Most DLBCL relapses occur within 24 months of starting treatment and patients who remain progression-free 24 months following initiation of first-line therapy have favourable survival outcomes.4 “After more than 20 years with very limited treatment advances, the approval of Polivy plus R-CHP marks a new era for people battling this aggressive disease,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “We are delighted that the European Commission has approved this Polivy regimen and believe it has the potential to make a significant impact on the lives of people with DLBCL.”“The approval of Polivy plus R-CHP in the first-line setting is great news for people in the EU diagnosed with this aggressive lymphoma, giving them a greater opportunity for positive outcomes,” said Professor Hervé Tilly, POLARIX Principal Investigator and Professor of Haematology at the University of Rouen. “Treatment with this regimen has been shown to reduce the chance of relapse and therefore need for subsequent treatments, limiting the burden of DLBCL.”Today’s EC approval was based on results from the phase III POLARIX study (GO39942), the first trial to show a clinically meaningful improvement in progression free survival (PFS), compared to standard of care rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), in people with previously untreated DLBCL. All patients were followed for at least 24 months and at a median follow-up of 28.2 months, results of the study showed a 27% reduction in the risk of disease worsening or death with Polivy plus R-CHP compared to R-CHOP in first-line DLBCL (hazard ratio [HR] 0.73; 95% confidence interval [CI]: 0.57–0.95; P<0.0177).6 The safety profile was comparable for Polivy plus R-CHP versus R-CHOP. The most frequently-reported (≥ 30%) adverse events with Polivy plus R-CHP were peripheral neuropathy (52.9%), nausea (41.6%), neutropenia (38.4%), and diarrhoea (30.8%).6 Results were presented for the first time in December 2021 at the 63rd American Society of Hematology Annual Meeting & Exposition and simultaneously published in the New England Journal of Medicine. The POLARIX study is being conducted in collaboration with The Lymphoma Study Association (LYSA) and The Lymphoma Academic Research Organisation (LYSARC).In addition to today’s approval, the EC also converted Polivy's initial conditional marketing authorisation in the EU for the treatment of adult patients with relapsed or refractory DLBCL, who are not candidates for a haematopoietic stem cell transplant, to a full approval.Roche continues to explore areas where Polivy has the potential to deliver additional benefit, including ongoing studies investigating combinations of Polivy with CD20xCD3 T-cell engaging bispecific antibodies in previously treated/untreated DLBCL.About Polivy® (polatuzumab vedotin)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 lymphoma (NHL), making it a promising target for the development of new therapies.7,8 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 minimise the effects on normal cells.9,10 Polivy is being developed by Roche using Seagen ADC technology and is currently being investigated for the treatment of several types of NHL.

The primary outcome measure is progression-free survival (PFS) as assessed by the investigator using the Lugano Response Criteria for malignant lymphoma. PFS is a clinically meaningful disease-related outcome for patients with previously untreated DLBCL as it represents the goal of first-line therapy: decreasing the risk of disease worsening. About the LYSA and the LYSARCThe Lymphoma Study Association, or LYSA, is the internationally leading cooperative group for lymphoma research in Europe, conducting clinical studies ranging from the first tests of new medicines in humans to the establishment of reference therapeutic strategies. LYSA includes in its network more than 90 care centres distributed throughout three countries (France, Belgium, Portugal), and collaborates with many scientific teams at the international level.The Lymphoma Academic Research Organisation, or LYSARC, is the LYSA operational structure that conducts clinical research projects on lymphomas at the international level.About diffuse large B-cell lymphoma (DLBCL)DLBCL is the most common form of non-Hodgkin lymphoma (NHL), accounting for about one in three cases of NHL. 2 DLBCL is an aggressive (fast-growing) type of NHL.2 While it is generally responsive to treatment in the frontline, as many as 40% of people will relapse or have refractory disease, at which time salvage therapy options are limited and survival is short.4,5 Approximately 150,000 people worldwide are estimated to be diagnosed with DLBCL each year.11About Roche in haematologyRoche has been developing medicines for people with malignant and non-malignant blood diseases for more than 20 years; our experience and knowledge in this therapeutic area runs deep.

TELLOMAK trial progresses as cohort 2 of KIR3DL2-expressing mycosis fungoides patients advances to Stage 2 earlier than anticipated Company to initiate two new clinical trials to investigate lacutamab in peripheral T-cell lymphoma, including Phase 2 combination study with leading global lymphoma research network, LYSA Webcast featuring key opinion leaders today at 2:00 p.m. CET / 8:00 a.m. ET MARSEILLE, France, Feb. 09, 2021 (GLOBE NEWSWIRE) -- Innate Pharma SA (Euronext Paris: IPH – ISIN: FR0010331421; Nasdaq: IPHA) (“Innate” or the “Company”) today announced new clinical developments for its first-in-class, proprietary investigational asset, lacutamab, an anti-KIR3DL2 cytotoxicity-inducing antibody in development for T-cell lymphomas. This includes advancement of the KIR3DL2-expressing mycosis fungoides (MF) cohort (cohort 2) to Stage 2 in the TELLOMAK study, as well as the initiation of the peripheral T-cell lymphoma (PTCL) clinical program. Mycosis Fungoides: Advancing TELLOMAK Cohort 2 to Stage 2 In TELLOMAK, an open-label, multi-cohort, Phase 2 trial, lacutamab demonstrated a positive early signal in cohort 2. This cohort reached the pre-determined number of responses needed to advance to stage 2, allowing the Company to recruit additional patients. The Company plans to present this preliminary data at a scientific meeting in 2021. Recruitment is ongoing in cohort 3, evaluating lacutamab as a monotherapy in KIR3DL2 non-expressing MF patients. Peripheral T-Cell Lymphoma: Introducing a Data-Driven Clinical Strategy The Company today announced plans to initiate two parallel clinical trials to study lacutamab in KIR3DL2-expressing patients with relapsed/refractory PTCL. Together these trials offer a data-driven strategy to identify potential opportunities for lacutamab in the relapsed setting, and potential expansion into earlier lines of therapy for PTCL in the future. Phase 1b trial: a Company-sponsored Phase 1b clinical trial to evaluate lacutamab as a monotherapy in KIR3DL2-expressing patients with relapsed PTCL. Phase 2 KILT (anti-KIR in T Cell Lymphoma) trial: The Lymphoma Study Association (LYSA) will launch an investigator-sponsored, randomized trial to evaluate lacutamab in combination with chemotherapy GEMOX (gemcitabine in combination with oxaliplatin) versus GEMOX alone in KIR3DL2-expressing relapsed/refractory patients. “Lacutamab is our priority clinical asset, and we are pleased to share important progress of this program. The early signal seen in the KIR3DL2-expressing mycosis fungoides patient population is encouraging and moves us past the pre-determined threshold for the cohort earlier than anticipated,” said Joyson Karakunnel, M.D., MSc, FACP, Chief Medical Officer Innate Pharma. “In addition, our PTCL trials announced today demonstrate our strategy to first explore lacutamab’s potential in the relapsed/refractory setting, then potentially in earlier lines of treatment. Partnering with LYSA will provide invaluable expertise given their track record in advancing therapeutics for the lymphoma community.” “Relapsed PTCL patients are in need of alternative, effective options and we are pleased to partner with Innate Pharma on this important study,” said Franck Morschhauser, Professor of Hematology in Lille (France) and President of LYSA. “KIR3DL2 represents a meaningful target, as it is expressed in up to 50% of PTCL across subtypes. Through our global network and deep expertise in lymphoma, we believe this study will help us better understand the potential for lacutamab to help these patients.” To learn more about these updates, join Innate’s executive leadership team, as well as Pierluigi Porcu, M.D., Professor of Medical Oncology, Dermatology and Cutaneous Biology and Director, Division of Hematologic Malignancies and Hematopoietic Stem Cell Transplantation at Jefferson University Hospital and principal investigator of Innate’s Phase 2 TELLOMAK study, and Olivier Hermine, M.D., Professor of Hematology at the University of Paris Descartes, Director, Division of Adult Hematology at Hôpital Universitaire Necker Enfants Malades and principal investigator of the LYSA Phase 2 KILT study for a virtual presentation today. Webcast and conference call will be held today at 2:00 p.m. CET / 8:00 a.m. ET Access to live webcast: Participants may also join via telephone by registering in advance of the event at . Upon registration, participants will be provided with dial-in numbers, a direct event passcode and a unique registrant id that they may use 10 minutes prior to the event start to access the call. This information can also be found on the Investors section of the Innate Pharma website, . A replay of the webcast will be available on the Company website for 90 days following the event. About Lacutamab: Lacutamab (IPH4102) is a first-in-class anti-KIR3DL2 humanized cytotoxicity-inducing antibody, which is currently in clinical trials for treatment of cutaneous T-cell lymphoma (CTCL), an orphan disease. This group of rare cutaneous lymphomas of T lymphocytes has 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 peripheral t-cell lymphoma (PTCL). It has a restricted expression on normal tissues. About TELLOMAK: TELLOMAK is a global, open-label, multi-cohort Phase 2 clinical trial recruiting patients with advanced T-cell lymphomas (TCL) in the United States and Europe. TELLOMAK is expected to recruit up to 150 patients, with lacutamab evaluated: As a single agent in approximately 60 patients with Sézary syndrome who have received at least two prior systemic therapies, including mogamulizumab. As a single agent in approximately 90 patients with mycosis fungoides (MF) who have received at least two systemic therapies. In patients with MF, the study is designed to evaluate the benefit of lacutamab according to KIR3DL2 expression. The study comprises two cohorts in MF, testing lacutamab in KIR3DL2 expressing and non-expressing patients determined at baseline. These cohorts follow a Simon 2-stage design that will terminate early if treatment is considered futile. The Sézary syndrome cohort of the study could enable the registration of lacutamab in this indication. The primary endpoint of the trial is objective response rate. Key secondary endpoints are progression-free survival, duration of response, quality of life and adverse events. About Lacutamab in PTCL: Two clinical trials will investigate lacutamab in KIR3DL2-expressing PTCL patients who have received at least one prior systemic therapy. Lacutamab is being evaluated: In a multi-center, Phase 1b clinical trial as a single agent in approximately 20 relapsed patients expressing KIR3DL2. The trial is designed to evaluate safety, as well as characterize clinical outcomes, pharmacokinetics and immunogenicity of lacutamab alone in PTCL. Further expansion will be determined based on preliminary efficacy signals. In a multi-center, randomized Phase 2 trial in combination with GEMOX in relapsed/refractory patients expressing KIR3DL2. This study will include approximately 60 patients. The combination trial, KILT (anti-KIR in T-Cell Lymphoma), is being conducted by the Lymphoma Study Association (LYSA) and its operational organization Lymphoma Academic Research Organisation (LYSARC); it will evaluate the efficacy and safety of lacutamab in combination with chemotherapy GEMOX in prescreened patients, with progression-free survival as the primary endpoint.
