Genentech Provides an Update on Phase III Study of Tecentriq in People With Muscle-invasive Urothelial Cancer

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III IMvigor010 study evaluating Tecentriq^® (atezolizumab) as an adjuvant (after surgery) monotherapy treatment did not meet its primary endpoint of disease-free survival (DFS) compared to observation in people with muscle-invasive urothelial cancer (MIUC). Safety for Tecentriq appeared consistent with the known safety profile of the medicine, and no new safety signals were identified.

"Reducing the risk that muscle-invasive urothelial cancer will recur after surgery is very difficult, and we are disappointed that we were not able to significantly prolong disease-free survival," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "We remain committed to exploring the potential benefits of immunotherapy for more people with early cancers."

The goal in treating MIUC early is to reduce the risk of the disease recurring or spreading to other parts of the body. More treatment options following surgery are needed as approximately half of people with MIUC will develop a recurrence of their disease within two years of surgery.

In addition to ongoing Phase III studies in early and advanced bladder cancer, Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies across genitourinary, skin, breast, gastrointestinal, gynecological and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.

About the IMvigor010 study

IMvigor010 is a global Phase III, open-label, randomized, controlled study designed to evaluate the efficacy and safety of adjuvant treatment with Tecentriq compared with observation in 809 people with MIUC, who are at high risk for recurrence following resection. The primary endpoint is DFS as assessed by investigator, which is defined as the time from randomization to invasive urothelial cancer recurrence or death.

About bladder cancer

According to the American Cancer Society (ACS), it is estimated that more than 81,000 Americans will be diagnosed with bladder cancer in 2020. Urothelial cancer is the most common type of bladder cancer, accounting for about 90-95% of all cases. MIUC is a type of urothelial cancer that has spread into the muscle wall of the bladder, ureter, or renal pelvis. Approximately 25% of people newly diagnosed with bladder cancer are diagnosed with muscle-invasive disease, which is associated with a poorer prognosis than non-MIUC.

About Tecentriq^® (atezolizumab)

Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

Tecentriq U.S. Bladder Indications

Tecentriq is a prescription medicine used to treat adults with:

A type of bladder and urinary tract cancer called urothelial carcinoma. Tecentriq may be used when your bladder cancer:

• has spread or cannot be removed by surgery, and if you have any one of the following conditions:
  • you are not able to take chemotherapy that contains a medicine called cisplatin, and your cancer tests positive for "PD-L1", or
  • you are not able to take chemotherapy that contains any platinum regardless of the levels of "PD-L1" status, or
  • you have tried chemotherapy that contains platinum, and it did not work or is no longer working.

The approval of Tecentriq in these patients is based on a study that measured response rate and duration of response. Continued approval for this use may depend on the results of an ongoing study to confirm benefit.

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

Important Safety Information
What is the most important information about Tecentriq?
Tecentriq can cause the immune system to attack normal organs and tissues and can affect the way they work. These problems can sometimes become serious or life threatening and can lead to death.

Patients should call or see their healthcare provider right away if they get any symptoms of the following problems or these symptoms get worse.

Tecentriq can cause serious side effects, including:

• Lung problems (pneumonitis)?signs and symptoms of pneumonitis may include new or worsening cough, shortness of breath, and chest pain
• Liver problems (hepatitis)?signs and symptoms of hepatitis may include yellowing of the skin or the whites of the eyes, severe nausea or vomiting, pain on the right side of the stomach area (abdomen), drowsiness, dark urine (tea colored), bleeding or bruising more easily than normal, and feeling less hungry than usual
• Intestinal problems (colitis)?signs and symptoms of colitis may include diarrhea (loose stools) or more bowel movements than usual, blood or mucus in stools or dark, tarry, sticky stools, and severe stomach area (abdomen) pain or tenderness
• Hormone gland problems (especially the thyroid, adrenal glands, pancreas, and pituitary)?signs and symptoms that the hormone glands are not working properly may include headaches that will not go away or unusual headaches, extreme tiredness, weight gain or weight loss, dizziness or fainting, feeling more hungry or thirsty than usual, hair loss, changes in mood or behavior (such as decreased sex drive, irritability, or forgetfulness), feeling cold, constipation, the voice gets deeper, urinating more often than usual, nausea or vomiting, and stomach area (abdomen) pain

Getting medical treatment right away may help keep these problems from becoming more serious. A healthcare provider may treat patients with corticosteroid or hormone replacement medicines. A healthcare provider may delay or completely stop treatment with Tecentriq if patients have severe side effects.

Before receiving Tecentriq, patients should tell their healthcare provider about all of their medical conditions, including if they:

• have immune system problems (such as Crohn's disease, ulcerative colitis, or lupus); have had an organ transplant; have lung or breathing problems; have liver problems; have a condition that affects the nervous system (such as myasthenia gravis or Guillain-Barre syndrome); or are being treated for an infection
