Genentech’s Alecensa Reduces the Risk of Disease Recurrence or Death by an Unprecedented 76% in People With ALK-Positive Early-Stage Non-Small Cell Lung Cancer

– These Phase III data are the first and only to show an improvement in disease-free survival in early-stage resected ALK-positive non-small cell lung cancer (NSCLC) –

– With about one in two people with early-stage NSCLC experiencing disease recurrence following surgery, despite adjuvant chemotherapy, more effective treatment options are urgently needed to provide the best chance for cure –

– Data are being presented as a late-breaking oral during an ESMO 2023 Presidential Symposium –

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced results from the primary analysis of the Phase III ALINA study demonstrating a statistically significant and clinically meaningful improvement in disease-free survival (DFS; primary endpoint). The study results showed that Alecensa^® (alectinib) reduces the risk of disease recurrence or death by 76% (hazard ratio [HR]=0.24, 95% CI: 0.13-0.43, p<0.0001) compared with platinum-based chemotherapy in people with completely resected Stage IB (tumor ≥4 cm) to IIIA (UICC/AJCC 7th edition) anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). A clinically meaningful improvement of central nervous system (CNS)-DFS was also observed (HR=0.22; 95% CI: 0.08-0.58). The safety and tolerability of Alecensa in this trial were consistent with previous trials in the metastatic setting and no unexpected safety findings were observed. Overall survival data were immature at the time of this analysis and follow-up is ongoing to report a more mature estimate.

The full results of ALINA are being presented as a late-breaking oral at the European Society of Medical Oncology (ESMO) Congress 2023 Presidential Symposium on Saturday, October 21, 2023. These data will be submitted to global health authorities, including the U.S. Food and Drug Administration and the European Medicines Agency.

“By reducing the risk of recurrence or death of ALK-positive early-stage NSCLC by an unprecedented 76%, Alecensa can potentially alter the course of this disease as we aim to provide the best chance for cure,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We urgently need to do more to help people with lung cancer, as about half of patients with early-stage NSCLC experience disease recurrence. We’re working with health authorities to bring Alecensa to patients in this setting as soon as possible.”

“These potentially practice-changing data reinforce the potential of Alecensa as a new standard of care in the ALK-positive early lung cancer setting where treatment options are currently extremely limited,” said Professor Benjamin Solomon, Medical Oncologist, Peter MacCallum Cancer Centre, Australia. “The magnitude of disease-free survival observed in this study could represent a paradigm shift in the way we manage early-stage ALK-positive lung cancer.”

Delaying disease progression is of particular importance for people with ALK-positive NSCLC, who are generally younger – usually around 55 – and are at higher risk of developing brain metastases than those with other types of NSCLC. Once the disease returns it often spreads to other parts of the body, at which point it is usually considered incurable. Comprehensive biomarker testing is essential to helping physicians secure a complete, personalized diagnosis and identify the right treatment for each patient.

Results from the primary analysis of the ALINA study showed median DFS was not yet reached for Alecensa compared with 41.3 months for chemotherapy (95% CI: 28.5, not evaluable [NE]). Grade 3 or 4 adverse events (AEs) occurred in 30% of people receiving Alecensa, compared with 31% of those receiving chemotherapy. No Grade 5 events were observed in either treatment arm. For those receiving Alecensa, 5.5% of patients discontinued treatment due to AEs versus 12.5% in the chemotherapy arm.

About the ALINA study

The ALINA study [NCT03456076] is a Phase III, randomized, active-controlled, multicenter, open-label study evaluating the efficacy and safety of adjuvant Alecensa^® (alectinib) compared with platinum-based chemotherapy in people with completely resected Stage IB (tumor ≥ 4 cm) to IIIA (UICC/AJCC 7th edition) anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). The study includes 257 patients who were randomly assigned to either the investigational or control treatment arm. The primary endpoint is disease-free survival (DFS). Secondary outcome measures include overall survival (OS) and percentage of patients with adverse events.

About lung cancer

According to the American Cancer Society, it is estimated that more than 238,000 Americans will be diagnosed with lung cancer in 2023, and NSCLC accounts for 80-85% of all lung cancers. Treating lung cancer early, before it has spread, may help prevent the disease from returning and provide people with the best opportunity for a cure.

About Alecensa^® (alectinib)

Alecensa is a prescription medicine used to treat people with non-small cell lung cancer that has spread to other parts of the body (mNSCLC) and is caused by an abnormal anaplastic lymphoma kinase (ALK) gene. A doctor will perform a test to make sure that Alecensa is right for their patient.

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

Important Safety Information

Everyone reacts differently to treatment with Alecensa. It’s important to know the most serious and most common side effects with Alecensa.

A doctor may lower the dose or stop treatment with Alecensa if any serious side effects occur. Patients taking Alecensa should contact their doctor right away if they have any of the following side effects.

Alecensa may cause serious side effects, including:

Liver problems (hepatotoxicity). Alecensa may cause liver injury. A doctor will do blood tests at least every 2 weeks for the first 3 months, and then 1 time each month and as needed during treatment with Alecensa. Patients taking Alecensa should tell their doctor right away if they experience any of the following signs and symptoms:

• Feeling tired
• Feeling less hungry than usual
• Yellowing of the skin or whites of the eyes
• Dark urine
• Itchy skin
• Nausea or vomiting
• Pain on the right side of stomach area
• Bleeding or bruising more easily than normal

Lung problems. Alecensa may cause severe or life-threatening swelling (inflammation) of the lungs during treatment. Symptoms may be similar to those symptoms from lung cancer. Patients taking Alecensa should tell their doctor right away if they have any new or worsening symptoms, including:

• Trouble breathing
• Shortness of breath
• Fever
• Cough

Kidney problems. Alecensa may cause severe or life-threatening kidney problems. Patients should tell their healthcare provider right away if they have a change in the amount or color of their urine, or if they get new or worsening swelling in their legs or feet.

Slow heartbeat (bradycardia). Alecensa may cause very slow heartbeats that can be severe. A doctor will check a patient’s heart rate and blood pressure during treatment with Alecensa. Patients taking Alecensa should tell their doctor right away if they feel dizzy, lightheaded, or faint during treatment with Alecensa. Patients taking Alecensa should tell their doctor if they take any heart or blood pressure medicines.

Muscle pain, tenderness, and weakness (myalgia). Muscle problems are common with Alecensa and can be severe. A doctor will do blood tests at least every 2 weeks for the first month and as needed during treatment with Alecensa. Patients taking Alecensa should tell their doctor right away if they have any new or worsening signs and symptoms of muscle problems, including unexplained muscle pain or muscle pain that does not go away, tenderness, or weakness.

Breakdown of healthy red blood cells earlier than normal (hemolytic anemia). Hemolytic anemia can happen in some people who take Alecensa. If this happens, patients may not have enough healthy red blood cells. Doctors may temporarily stop Alecensa and do blood tests, if needed, to check for this problem. If patients develop hemolytic anemia, their doctor may either restart them on Alecensa at a lower dose when the hemolytic anemia goes away, or may stop treatment with Alecensa. Patients should tell their doctor right away if they experience yellow skin (jaundice), weakness or dizziness, or shortness of breath.

Before taking Alecensa, patients should tell their doctor about all medical conditions, including if they:

• Have liver problems
• Have lung or breathing problems
• Have a slow heartbeat
• Are pregnant or plan to become pregnant. Alecensa can harm an unborn baby. Patients taking Alecensa should tell their doctor right away if they become pregnant during treatment with Alecensa or think they may be pregnant
  • Women who are able to become pregnant should use effective birth control during treatment with Alecensa and for one week after the final dose of Alecensa
  • Men who have female partners that are able to become pregnant should use effective birth control during treatment with Alecensa and for three months after the final dose of Alecensa
• Are breastfeeding or plan to breastfeed. It is not known if Alecensa passes into breast milk. A patient should not breastfeed during treatment with Alecensa and for one week after the final dose of Alecensa. Patients should talk with their doctor about the best way to feed their baby during this time.

Patients taking Alecensa should tell their doctor about all the medicines they take, including prescription medicines, over-the-counter medicines, vitamins, and herbal supplements.

Patients taking Alecensa should avoid spending time in the sunlight during treatment with Alecensa and for seven days after the final dose of Alecensa.
