Tecentriq: teh-SEN-trik


What cancer(s) does this drug treat?

Tecentriq has been approved for a number of cancer types and stages, in some cases as a single therapy and in some cases in combination with other therapies.

Tecentriq is approved for:

Advanced non-small cell lung cancer
Small cell lung cancer
Liver cancer
Melanoma
Sarcoma

Non-small cell lung cancer

Tecentriq is approved for:

  • Patients with non-small cell lung cancer that has been removed by surgery and treated with platinum-based chemotherapy, and tests positive for high levels of the PD-L1 molecule.
  • Patients with nonsquamous non-small cell lung cancer that has spread and does not have an abnormal EGFR or ALK gene. In such cases, Tecentriq may be used in combination with bevacizumab (Avastin, Mvasi, Zirabev), paclitaxel (Taxol or Onxal), and carboplatin (Paraplatin) as a first treatment. Alternatively, Tecentriq may be used in combination with paclitaxel protein-bound (Abraxane) and carboplatin (Paraplatin) as a first treatment.
  • Patients with non-small cell lung cancer that has spread, whose tumors test positive for high levels of the PD-L1 molecule, and whose tumors do not have an abnormal EGFR or ALK gene. In such cases, Tecentriq is used as a first treatment.
  • Patients with non-small cell lung cancer that has spread. The patient must have already tried chemotherapy containing platinum and it either did not work or stopped working. If the patient’s tumor has an abnormal EGFR or ALK gene, the patient has to have also tried therapy for tumors with such abnormal genes prior to receiving Tecentriq.

Advanced small cell lung cancer

Tecentriq is approved for:

  • Patients with extensive-stage small cell lung cancer that has grown or spread. In such cases, Tecentriq may be used in combination with chemotherapies carboplatin (Paraplatin) and etoposide (Etopophos) as a first treatment.

Advanced liver cancer

Tecentriq is approved for:

  • Patients with liver cancer (hepatocellular carcinoma) that could not be removed by surgery or has spread to other parts of the body, and who have not yet received systemic therapy (therapy by mouth or injection into the vein [i.v.]) for their disease. In such cases, Tecentriq is used in combination with bevacizumab (Avastin, Mvasi, Zirabev).

Advanced melanoma

Tecentriq is approved for:

  • Patients with melanoma that could not be removed by surgery or had spread to other parts of the body, and who tested positive for the BRAF V600 mutation. In such cases, Tecentriq is given in combination with cobimetinib (Cotellic) and vemurafenib (Zelboraf).

Alveolar soft part sarcoma

Tecentriq is approved for:

  • Adult and pediatric patients (2 years and older) with alveolar soft part sarcoma that cannot be removed by surgery or has spread to other parts of the body.

Limitations of use:

Age: The safety and efficacy of Tecentriq have been established in pediatric patients with alveolar soft part sarcoma 2 years of age or older, but not in patients less than 2 years old. The safety and efficacy of Tecentriq in patients under 18 years of age have not been established for any other indications.
Fertility/Pregnancy/Breastfeeding: Tecentriq may impair fertility in women while receiving treatment. Tecentriq can cause harm to a fetus, and is not recommended for use during pregnancy. Pregnancy should be prevented for at least five months after the last dose of Tecentriq. The risks associated with Tecentriq during breastfeeding are not known and cannot be ruled out. Due to the potential for serious adverse reactions in the breastfed child, women are advised not to breastfeed during treatment and for at least five months after the last dose of Tecentriq.
Complications of stem cell transplant: Serious and life-threatening complications that can lead to death can occur in patients who have received a stem cell transplant from a stem cell donor before or after being treated with Tecentriq.


What type of immunotherapy is this?

Checkpoint blockade

  • PD-L1 blockade

How does this drug work?

  • Target: PD-L1

Tecentriq is an antibody that attaches to a molecule called PD-L1, which is sometimes present on the surface of cancer cells or other cells within the tumor mass. PD-L1 interacts with a molecule called PD-1, which is present on the surface of T cells– the primary immune cells involved in killing cancer cells. In healthy tissues, the interaction between PD-L1 and PD-1 puts on a brake that keeps T cells from creating an immune reaction that gets out of control. However, cancers can hijack this safety mechanism and prevent T cells from doing their job – killing the cancer cells. When PD-L1 interacts with PD-1 on T cells, the T cells become inactive and do not attack the cancer cells. Tecentriq binds to the PD-L1 molecules on cancer cells and other cells within the tumor mass in such a way that it blocks the interaction between PD-1 and PD-L1, and allows the T cells to be active and attack the cancer cells.

How is this drug given to the patient?

Tecentriq is administered via a tube into a vein (intravenous infusion, or i.v.) over 60 minutes every two, three, or four weeks (depending on the dose) and does not require a hospital stay. If the first infusion is tolerated, all following infusions may be administered over 30 minutes.


What are the observed clinical results?

For:

Non-small cell lung cancer (removed by surgery)
Advanced non-small cell lung cancer (previously untreated with chemotherapy)
Advanced non-small cell lung cancer (previously treated with chemotherapy)
Advanced small cell lung cancer
Advanced liver cancer
Advanced melanoma
Alveolar soft part sarcoma

It is important to keep in mind that each patient’s actual outcome is individual and may be different from the results found in the clinical studies. In addition, with immunotherapy, sometimes it takes several months for responses to be observed.

Non-small cell lung cancer (removed by surgery)

In a clinical trial, 1005 patients with non-small cell lung cancer were either treated with Tecentriq or best supportive care following complete surgical removal of all known disease and cisplatin-based chemotherapy. Among 476 patients whose tumor tested positive for the PD-L1 molecule, at a median follow-up of 32 months:

Advanced non-small cell lung cancer (previously untreated with chemotherapy)

In a clinical trial of patients with nonsquamous non-small cell lung cancer that had spread and who had not previously been treated with chemotherapy for their advanced disease, patients were treated with one of the following three treatment options:

  • Treatment 1: Tecentriq in combination with paclitaxel (Taxol or Onxal) and carboplatin (Paraplatin)
  • Treatment 2: Tecentriq in combination with bevacizumab (Avastin), paclitaxel (Taxol or Onxal), and carboplatin (Paraplatin)
  • Treatment 3: bevacizumab (Avastin), paclitaxel (Taxol or Onxal), and carboplatin (Paraplatin)

In the 1045 of 1202 enrolled patients whose cancer did not have an abnormal EGFR or ALK gene, at a median follow-up of 20 months, the following results were observed for patients receiving either Treatment 2 or 3:

(Results for patients receiving Treatment 1 did not significantly differ from the results observed with Treatment 3, and the combination used in the Treatment 1 arm did not receive approval.)

Advanced non-small cell lung cancer (previously treated with chemotherapy)

In a clinical trial of patients with non-small cell lung cancer that had grown or spread and who had already tried chemotherapy containing platinum, but it either did not work or stopped working, patients were treated with either Tecentriq or docetaxel (a chemotherapy). In the first 850 treated patients, at a median follow-up of 21 months following treatment:

Advanced small cell lung cancer

In a clinical trial of 403 patients with extensive-stage small cell lung cancer that had grown or spread and who had not been treated with chemotherapy for their advanced disease, patients were treated with either Tecentriq in combination with the chemotherapies carboplatin (Paraplatin) and etoposide (Etopophos), or with a placebo in combination with carboplatin (Paraplatin) and etoposide (Etopophos). At a median follow-up of 14 months following treatment:

Alveolar soft part sarcoma

In a clinical trial, 49 adult and pediatric patients (2 years and older) with alveolar soft part sarcoma that could not be removed by surgery or had spread to other parts of the body, were treated with Tecentriq. 24% of patients saw shrinkage of their tumors. Of these patients, 67% continued to respond to therapy for more than 6 months and 47% experienced a response that lasted for 12 months or longer.


What are the side effects?

The most common side effects of Tecentriq include fatigue, weakness, nausea, decreased appetite, cough, and shortness of breath. When Tecentriq is used in combination with other drugs, other common side effects include diarrhea, constipation, vomiting, hair loss, headache, tingling or numbness in hands or feet, pain (in the muscles, bones, and joints), skin rash, heightened skin sensitivity to sunlight, low red blood cell count (anemia), and low white blood cell count.

Tecentriq can cause the patient’s T cells to attack healthy cells throughout the body. Because of this, Tecentriq can cause side effects that can become serious or life-threatening, and may lead to death. Some of the serious side effects related to Tecentriq include inflammation of the lungs, liver, or colon. Additionally, problems can arise with the heart, vision, and hormone glands (including thyroid, pituitary, and adrenal glands, as well as the pancreas). Tecentriq may cause Type 1 diabetes. Skin blisters and reactions related to the infusion may also occur. Patients should report any symptoms to their healthcare provider, who can then initiate actions to limit or reverse the side effects.
