LDK378

J. Med. Chem. 2013, DOI:10.1021/jm400402q).

CAS Number:
1032900-25-6
Mol. Formula:
C28H36ClN5O3S
MW:
558.13
LDK378 is a highly selective, orally bioavailable and ATP-competitive small molecule inhibitor of ALK (Anaplastic Lymphoma Kinase), a receptor tyrosine kinase considered to be an important lung cancer drug target. LDK378 displays enhanced potency over Crizotinib and noteworthy antitumor activity for ALK-activated, non-small cell lung cancer (NSCLC).

Alessandro Riva, MD, Global Head of Oncology Development & Medical Affairs for Novartis Oncology,
The FDA recently designated LDK378 as a breakthrough therapy based on encouraging results from early clinical trials in patients with ALK-positive, non-small-cell lung cancer.

Novartis investigational drug LDK378, a selective inhibitor of the cancer target anaplastic lymphoma kinase (ALK), shows a marked clinical response in patients with ALK+ non-small cell lung cancer (NSCLC) during the 49th Annual Meeting of the American Society of Clinical Oncology (ASCO) on June 3, 2013.

Doctors and patients are clamoring for more ways to fight lung cancer, the leading cause of cancer deaths in the U.S., of which NSCLC is the most common form. In March, LDK378 received Breakthrough Therapy designation from the US Food and Drug Administration (FDA). The designation is intended to expedite the development and review of drugs that treat life-threatening conditions and show improvement over available therapies.

Currently, two Phase II clinical trials are actively recruiting patients worldwide. One study focuses on patients with ALK+ NSCLC who were previously treated with chemotherapy and crizotinib (NCT01685060). The second study examines LDK378 in patients who are crizotinib-naive (NCT01685138). In addition, Phase III clinical trials are planned to begin in the coming months, aiming to enroll more than 1,100 patients with ALK+ NSCLC at sites worldwide. Novartis plans to file for approval the drug in early 2014.

Chemical Name of LDK378

5-chloro-N2-(2-isopropoxy-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(2-(isopropylsulfonyl)phenyl)pyrimidine-2,4-diamine

Technical Data of LDK378
1H NMR (400 MHz, DMSO-d6 + trace D2O) δ 8.32 (s,1H), 8.27 (d, 1H), 7.88 (d, 1H), 7.67 (dd, 1H), 7.45 (dd, 1H), 7.42 (s, 1H), 6.79 (s, 1H), 4.56 – 4.48(m, 1H), 3.49 – 3.32 (m, 3H), 3.10 - 2.91 (m, 3H), 2.09 (s, 3H), 1.89 – 1.77 (m, 4H), 1.22 (d, 6H), 1.13 (d, 6H); ESMS m/z 558.1 (M + H+).

The compound LDK378, a highly selective inhibitor of ALK, has been granted “Breakthrough Therapy Designation” by the FDA for the treatment of patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) who have already received treatment with crizotinib (Xalkori).

    Hi, Am the spouse of a patient you’ve used as your clinical trial studies. The patient was selected in Philippines for your study but suddenly stop everything and advice the patient to pay a huge amount of money once commercially available. Now patient’s condition recurring without treatment for almost 6 months.
    Should there be any option to assist him?

    Thankyou for your kind response.
