Metastatic human epidermal growth factor 2 positive carcinoma of breast

ItovebiTM (inavolisib)-based regimen demonstrated a statistically significant and clinically meaningful benefit, reducing the risk of disease worsening or death by 57% compared with palbociclib and fulvestrant alone in the INAVO120 study1 The U.S. FDA recently approved the Itovebi-based regimen as a first-line treatment for people with HR-positive, HER2-negative breast cancer with a PIK3CA mutation, one of the most commonly mutated genes in HR-positive disease2 Basel, 31 October 2024 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that a detailed analysis of the positive phase III INAVO120 results, evaluating ItovebiTM (inavolisib) in combination with palbociclib (Ibrance®) and fulvestrant were published in the New England Journal of Medicine.1 The United States Food and Drug Administration (FDA) recently approved Itovebi in combination with palbociclib and fulvestrant, for the treatment of adults with endocrine-resistant, PIK3CA-mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer, as detected by an FDA-approved test, following recurrence on or after completing adjuvant endocrine therapy. Data from INAVO120 are also being used for filing submissions to other global health authorities, including the European Medicines Agency. “With a doubling of progression-free survival and consistent benefits in people whose disease had spread to multiple challenging-to-treat locations, including the liver and lungs, these INAVO120 data are significant for patients,” said Komal Jhaveri, M.D., section head for the endocrine therapy research portfolio and clinical director of the early drug development service at Memorial Sloan Kettering Cancer Center and one of the principal investigators of the INAVO120 study. “I’m confident this Itovebi-based regimen could become a new first-line standard of care for this patient population with one of the most commonly mutated genes in metastatic breast cancer, associated with a poor prognosis.” Results showed the Itovebi-based regimen reduced the risk of disease worsening or death (progression-free survival [PFS]) by 57% compared to palbociclib and fulvestrant alone (15.0 months vs. 7.3 months; hazard ratio [HR]=0.43, 95% CI: 0.32-0.59, p<0.001).1 PFS benefit was consistent across all pre-specified subgroups, including people whose disease had spread to three or more locations, which is characterised as difficult-to-treat disease.1 Overall survival (OS) data were immature at the time of analysis, but a clear positive trend has been observed (stratified HR=0.64, 95% CI: 0.43-0.97, p=0.03 [boundary of 0.0098]).1 Follow-up for OS will continue to the next analysis.1 “Publication of these phase III results in the New England Journal of Medicine further highlights the transformative potential of the Itovebi-based regimen,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “This new treatment exemplifies our ambition to target specific disease pathways more effectively and improve outcomes in people with breast cancer, while also emphasising the importance of comprehensive testing for mutations like PIK3CA at the time of diagnosis.” The PIK3CA mutation is found in approximately 40% of HR-positive metastatic breast cancers and is associated with a poor prognosis.2,3 Historically, the use of PI3K targeted therapy in the first-line advanced setting has been limited and therefore testing for PIK3CA mutations is not common at the time of diagnosis.4 Early biomarker testing with an FDA-approved test, such as Foundation Medicine’s FoundationOne®Liquid CDx, before first-line treatment is crucial to help identify people who may benefit from targeted therapy, such as Itovebi.4,5 Itovebi is currently being investigated in three company-sponsored phase III clinical studies (INAVO120, INAVO121, INAVO122) in PIK3CA-mutated locally advanced or metastatic breast cancer in various combinations.6-8 We are exploring additional studies in breast cancer and other tumour types with the hope of bringing the benefit of this targeted therapy to more people with PIK3CA mutations and addressing patient unmet needs. About the INAVO120 studyThe INAVO120 study [NCT04191499] is a phase III, randomised, double-blind, placebo-controlled study evaluating the efficacy and safety of Itovebi (inavolisib) in combination with palbociclib and fulvestrant versus placebo plus palbociclib and fulvestrant in people with PIK3CA-mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.6 The study included 325 patients, who were randomly assigned to either the investigational or control treatment arm.6 The primary endpoint is progression-free survival, as assessed by investigators, defined as the time from randomisation in the clinical trial to the time when the disease progresses, or a patient dies from any cause.6 Secondary endpoints include overall survival, objective response rate, and clinical benefit rate.6 Beyond INAVO120, Itovebi is currently being investigated in two additional company-sponsored phase III clinical studies in PIK3CA-mutated locally advanced or metastatic breast cancer in various combinations:7,8 in combination with fulvestrant versus alpelisib plus fulvestrant in HR-positive/HER2-negative breast cancer post cyclin-dependent kinase 4/6 inhibitor and endocrine combination therapy (INAVO121; NCT05646862), andin combination with pertuzumab plus trastuzumab for subcutaneous injection (SC) versus pertuzumab plus trastuzumab for SC and optional physician's choice of endocrine therapy as a maintenance treatment in HER2-positive disease (INAVO122; NCT05894239). About hormone receptor (HR)-positive breast cancerHR-positive breast cancer is the most prevalent type of all breast cancers, accounting for approximately 70% of cases.9,10 A defining feature of HR-positive breast cancer is that its tumour cells have receptors that attach to one or both hormones – oestrogen or progesterone – which can contribute to tumour growth. People diagnosed with HR-positive metastatic breast cancer often face the risk of disease progression and treatment side effects, creating a need for additional treatment options.10-12 The PI3K signalling pathway is commonly dysregulated in HR-positive breast cancer, often due to activating PIK3CA mutations, which have been identified as a potential mechanism of intrinsic resistance to standard of care endocrine therapy in combination with cyclin-dependent kinase 4/6 inhibitors.3 About Roche in breast cancerRoche has been advancing breast cancer research for more than 30 years with the goal ofhelping as many people with the disease as possible.

Please see full Prescribing Information , including Boxed Warning. About HER2-positive Breast Cancer Human epidermal growth factor receptor 2 (HER2) is a protein found on the surface of some cancer cells that promotes growth and is associated with aggressive disease and poor prognosis. Approximately 15-20% of breast cancer cases are HER2-positive. Monoclonal antibodies targeting HER2 have greatly improved outcomes; however, a significant number of patients progress to later lines of therapy. Effective treatments for metastatic HER2-positive breast cancer continue to remain an unmet need. About MARGENZA MARGENZA (margetuximab-cmkb) is an Fc-engineered, monoclonal antibody that targets the HER2 oncoprotein. HER2 is expressed by tumor cells in breast, gastroesophageal and other solid tumors. Similar to trastuzumab, margetuximab-cmkb inhibits tumor cell proliferation, reduces shedding of the HER2 extracellular domain and mediates antibody-dependent cellular cytotoxicity (ADCC). However, through MacroGenics’ Fc Optimization technology, margetuximab-cmkb has been engineered to enhance the engagement of the immune system. In vitro, the modified Fc region of margetuximab-cmkb increases binding to the activating Fc receptor FCGR3A (CD16A) and decreases binding to inhibitor Fc receptor FCGR2B (CD32B). These changes lead to greater in vitro ADCC and NK cell activation. The clinical significance of in vitro data is unknown. About MacroGenics, Inc.

– Approval is based on Phase III INAVO120 results, showing the Itovebi TM (inavolisib)-based regimen more than doubled progression-free survival compared with palbociclib and fulvestrant alone in the first-line setting – – This approval helps address an urgent unmet need in breast cancer for people with a PIK3CA mutation, one of the most commonly mutated genes in HR-positive disease, associated with poor prognosis – – Itovebi is Genentech’s first targeted therapy approved for people with HR-positive disease, the most prevalent breast cancer subtype, marking an important step in our ambition to continue bringing innovative medicines to more people with breast cancer – SOUTH SAN FRANCISCO, CA, USA I October 10, 2024 I Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) approved Itovebi™ (inavolisib), in combination with palbociclib (Ibrance ® ) and fulvestrant, for the treatment of adults with endocrine-resistant, PIK3CA -mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer, as detected by an FDA-approved test, following recurrence on or after completing adjuvant endocrine therapy. The PIK3CA mutation is found in approximately 40% of HR-positive metastatic breast cancers. “The PI3K pathway plays a pivotal role in disease progression and has been challenging to target,” said Komal Jhaveri, M.D., section head for the endocrine therapy research portfolio and clinical director of the early drug development service at Memorial Sloan Kettering Cancer Center, and one of the principal investigators of the INAVO120 study. “The Itovebi-based regimen more than doubled progression-free survival and maintained a manageable safety and tolerability profile, adding a new standard in how PIK3CA -mutated breast cancers are treated.” “With the approval of this Itovebi-based regimen, we continue our long-standing track record of cancer therapeutic discovery by offering an important new first-line option for people living with HR-positive breast cancer with a PIK3CA mutation,” said Levi Garraway, M.D., Ph.D., Genentech’s chief medical officer and head of Global Product Development. “Despite the high prevalence of PIK3CA mutations in this setting, treatment options have thus far remained limited, which makes today’s approval all the more significant.” This approval is based on results of the pivotal Phase III INAVO120 study, which showed that the Itovebi-based regimen reduced the risk of disease worsening or death by 57% compared with palbociclib and fulvestrant alone (15.0 months vs. 7.3 months; hazard ratio [HR]=0.43, 95% CI: 0.32-0.59, p<0.0001) in the first-line setting, demonstrating a statistically significant and clinically meaningful benefit. Overall survival (OS) data were immature at the time of primary analysis, but a clear positive trend was observed (stratified HR=0.64, 95% CI: 0.43-0.97, p=0.0338 [boundary of 0.0098]). Follow-up for OS is continuing to the next analysis. “We are thrilled by the approval of the Itovebi-based regimen, which is a huge step forward for advanced breast cancer patients with a PIK3CA mutation,” said Jean Sachs, CEO of Living Beyond Breast Cancer. “It remains critical that all patients have access to early, comprehensive biomarker testing so they can better understand what treatment options may be most beneficial for them and their tumor type.” The Itovebi-based regimen was granted FDA Priority Review and Breakthrough Therapy Designation in May 2024 based on the INAVO120 study results. Data from INAVO120 are also being used for filing submissions to other global health authorities, including the European Medicines Agency. Itovebi will be available in the U.S. in the coming weeks. Early, comprehensive biomarker testing with an FDA-approved test, such as Foundation Medicine’s FoundationOne ® Liquid CDx, can help identify people with HR-positive, HER2-negative breast cancer with a PIK3CA mutation. Itovebi is currently being investigated in various combinations across three company-sponsored Phase III clinical studies (INAVO120, INAVO121, INAVO122) in PIK3CA -mutated locally advanced or metastatic breast cancer. We continue to evaluate opportunities to expand our clinical development program to address patient unmet needs in various tumor types across oncology. About the INAVO120 study The INAVO120 study [NCT04191499] is a Phase III, randomized, double-blind, placebo-controlled study evaluating the efficacy and safety of Itovebi (inavolisib) in combination with palbociclib and fulvestrant versus placebo plus palbociclib and fulvestrant in people with PIK3CA -mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease. The study included 325 patients, who were randomly assigned to either the investigational or control treatment arm. The primary endpoint is progression-free survival, as assessed by investigators, defined as the time from randomization in the clinical trial to the time when the disease progresses, or a patient dies from any cause. Secondary endpoints include overall survival, objective response rate, and clinical benefit rate. Beyond INAVO120, Itovebi is currently being investigated in two additional company-sponsored Phase III clinical studies in PIK3CA -mutated locally advanced or metastatic breast cancer in various combinations: About Hormone Receptor (HR)-Positive Breast Cancer HR-positive breast cancer is the most prevalent type of all breast cancers, accounting for approximately 70% of cases.

People diagnosed with HR-positive metastatic breast cancer often face the risk of disease progression and treatment side effects, creating a need for additional treatment options. The PI3K signaling pathway is commonly dysregulated in HR-positive breast cancer, often due to activating PIK3CA mutations, which have been identified as a potential mechanism of intrinsic resistance to standard of care endocrine therapy in combination with cyclin-dependent kinase 4/6 inhibitors. What is Itovebi? Itovebi (inavolisib) is a prescription medicine used in combination with the medicines palbociclib and fulvestrant to treat adults who have hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer that has an abnormal phosphatidylinositol-3-kinase catalytic subunit alpha ( PIK3CA ) gene, and has spread to nearby tissue or lymph nodes (locally advanced), or to other parts of the body (metastatic), and has come back after hormone (endocrine) therapy. Your healthcare provider will test your cancer for abnormal PIK3CA genes to make sure that Itovebi is right for you. It is not known if Itovebi is safe and effective in children. Important Safety Information What are the possible side effects of Itovebi? Itovebi may cause serious side effects, including: Your healthcare provider may tell you to decrease your dose, temporarily stop your treatment, or completely stop your treatment with Itovebi if you develop certain serious side effects. The most common side effects and abnormal blood test results of Itovebi when used in combination with palbociclib and fulvestrant include: Itovebi may affect fertility in males and in females who are able to become pregnant. Talk to your healthcare provider if this is a concern for you. These are not all the possible side effects of Itovebi. Call your healthcare provider for medical advice about side effects.
