Larotrectinib Sulfate and Preven EC

• Generic Name: larotrectinib
• Dosage Forms: n.a.
• Other Brand Names: Vitrakvi

Treatment of solid tumors harboring an NTRK fusion (without a known acquired mutation for resistance) in patients who have metastatic disease or may experience severe morbidity following surgical resection and whose disease progressed following prior therapy or those who are not candidates for other treatment options (designated an orphan drug by FDA for these cancers).

Accelerated approval based on overall response rate and duration of response. Continued approval may be contingent on verification and description of clinical benefit in confirmatory studies.

Confirmation of the presence of NTRK fusion is necessary prior to initiation of therapy. In clinical studies, NTRK fusion status of tumor specimens was determined by fluorescence in situ hybridization (FISH), reverse transcription-polymerase chain reaction (RT-PCR), or next-generation sequencing (NGS).

Preven EC contains a combination of ethinyl estradiol and levonorgestrel. Ethinyl estradiol and levonorgestrel are forms of estrogen and progesterone, which are both female hormones involved in conception.

Preven EC is used as an emergency contraceptive (EC) to prevent pregnancy after contraceptive failure or unprotected intercourse. Preven EC prevents ovulation (the release of an egg from an ovary), disrupt fertilization (joining of the egg and sperm), and inhibit implantation (attachment of a fertilized egg to the uterus).
