FDA Grants Genentech’s Alecensa Priority Review for Initial Treatment of People with ALK-Positive Lung Cancer

Excerpt:

“Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental New Drug Application (sNDA) and granted Priority Review for Alecensa® (alectinib) as an initial (first-line) treatment for people with anaplastic lymphoma kinase (ALK)-positive, locally advanced or metastatic non-small cell lung cancer (NSCLC) as detected by an FDA-approved test. The FDA will make a decision on approval by November 30, 2017.

” ‘Phase III results showed Alecensa reduced the risk of disease worsening by more than half compared to the current standard of care and lowered the risk of tumors spreading to or growing in the brain by more than 80 percent,’ said Sandra Horning, M.D., chief medical officer and head of Global Product Development. ‘We are working closely with the FDA to bring this medicine as an initial treatment for people with ALK-positive NSCLC as soon as possible.’ ”

Lorlatinib Shows Promise Against Brain Metastases in ALK+ Lung Cancer

Excerpt:

“Lorlatinib exhibits durable responses in pretreated patients with ALK-positive non–small-cell lung cancer (NSCLC) and promising intracranial activity and tumor responses in those patients who have brain metastases, regardless of prior therapy, according to findings from a phase I/II clinical study (abstract 9006) presented at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting, held June 2–6 in Chicago.

” ‘Lorlatinib demonstrated clinically meaningful and durable responses in ALK-positive patients receiving one or more prior ALK TKI [tyrosine kinase inhibitor], many of whom were heavily pretreated,’ said coauthor Sai-Hong Ignatius Ou, MD, of the University of California Irvine Chao Family Comprehensive Cancer Center in Orange, California.”

Alectinib Halts Lung Cancer Growth More Than a Year Longer Than Crizotinib

Excerpt:

“Findings from a phase III clinical trial point to a more effective initial treatment for patients with ALK-positive non-small cell lung cancer (NSCLC). Compared to the current standard of care crizotinib (Xalkori), the newer ALK inhibitor alectinib (Alecensa) halted cancer growth for a median of 15 months longer and caused fewer severe side effects.

“The study will be featured in a press briefing today and presented at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting.”

FDA Broadens Ceritinib Indication to Previously Untreated ALK-Positive Metastatic NSCLC

Excerpt:

“On May 26, 2017, the U.S. Food and Drug Administration granted regular approval to ceritinib (ZYKADIA, Novartis Pharmaceuticals Corp.) for patients with metastatic non-small cell lung cancer (NSCLC) whose tumors are anaplastic lymphoma kinase (ALK)-positive as detected by an FDA-approved test.

“In April 2014, ceritinib received accelerated approval for patients with ALK-positive metastatic NSCLC whose disease has progressed or who are intolerant to crizotinib based on a blinded independent review committee (BIRC)-assessed overall response rate (ORR) of 44% among 163 patients in a single-arm trial.”

Brigatinib First to Offer over 1-Year Control of ALK-Positive Lung Cancer Post-Crizotinib

Excerpt:

“About 3-5 percent of lung cancers are caused by changes in the gene ALK. In 2011, the FDA granted accelerated approval for the drug crizotinib to target these ALK changes. However, two major problems have remained: Crizotinib does not pass into the brain and so is unable to target ALK-positive lung cancer in the central nervous system, and the genetic diversity of cancer allows the later growth of subpopulations that can resist the drug, leading to renewed growth. In response, researchers have been actively developing next-generation ALK-inhibitors.

“Results of a multi-center, 222-person phase 2 clinical trial of the next-generation ALK inhibitor, brigatinib at 180mg/day, used after failure of crizotinib showed a 54 percent response rate and 12.9 month progression-free survival. (Effects were lower at a lower dose.) Results are published in the Journal of Clinical Oncology.”

FDA Approves Alunbrig (brigatinib) for Rare Lung Cancer

Excerpt:

“On Friday evening, Takeda Pharmaceuticals announced the FDA has approved Alunbrig (brigatinib) to treat patients with anaplastic lymphoma kinase-positive (ALK+) metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib.

“Brigatinib is a kinase inhibitor that can be taken orally. The recommended dose is 90 mg orally once daily for the first 7 days. If 90 mg is tolerated during the first 7 days, patient should increase the dose to 180 mg orally once daily. The pill can be taken with or without food.”

FDA Grants Lorlatinib Breakthrough Designation for NSCLC

Excerpt:

“The FDA has granted a breakthrough therapy designation to lorlatinib for use in patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) who have previously received 1 or more ALK inhibitors, according to Pfizer, the company developing the next-generation ALK/ROS1 tyrosine kinase inhibitor (TKI).

” ‘This regulatory designation recognizes the potential for lorlatinib to provide an important treatment option for patients with ALK-positive NSCLC whose cancers have progressed despite treatment,’ Mace Rothenberg, MD, chief development officer, Oncology, Pfizer Global Product Development, said in a release. ‘Pfizer’s rapid development of lorlatinib reflects a commitment to developing biomarker-driven therapies to meet the evolving needs of patients.’ ”

Roche’s Alecensa Beats Pfizer’s Xalkori in Lung Cancer Trial

Excerpt:

“Roche has presented late-stage data showing that its Alecensa was superior to Pfizer’s Xalkori on progression-free survival in patients with a specific type of lung cancer.

“The global, randomised Phase III ALEX study hit its primary endpoint in showing that Alecensa (alectinib) as a first-line treatment significantly reduced the risk of disease worsening or death (progression-free survival, PFS) versus Xalkori (crizotinib) in people with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC).”

Frontline Setting for ALK+ NSCLC Set to Undergo Shift

Excerpt:

“Currently available as a second-line therapy for patients with ALK-positive non–small cell lung cancer (NSCLC), alectinib’s (Alecensa) frontline potential is being explored in the ongoing phase III ALEX study (NCT02075840), which could transform first-line treatment for these patients.

“This study is comparing alectinib with crizotinib (Xalkori)—a current first-line option—in the frontline setting for patients with ALK-positive NSCLC. The oncology community is anticipating reports on the data in the first half of 2017.”
