Larodx (Larotrectinib) 25mg/100mg×60 Capsules | BigBear Laos NTRK Fusion | GLT

Generic Information: Larodx (Larotrectinib) — BigBear Pharma, Laos

Larodx is the larotrectinib capsule of BigBear Pharmaceutical Co., Ltd., the Vientiane-based manufacturer that also markets several other fusion-driven and targeted oncology generics. The range is complete for titration: two strengths, 25 mg and 100 mg, each in a 60-capsule bottle. The two-strength design means a prescriber can hold the standard 100 mg twice-daily dose while having the 25 mg capsule on hand for the 75 mg and 50 mg reduction steps, all within a single brand.

What Is Larodx (Larotrectinib) Used For?

Larodx treats adult and pediatric patients with solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, where disease is metastatic or surgery would likely cause severe morbidity, and where there is no satisfactory alternative or the cancer has progressed after treatment. Because selection is by fusion rather than organ, the drug covers infantile fibrosarcoma, salivary gland cancer, soft-tissue sarcoma, thyroid cancer, lung cancer and other NTRK fusion-positive solid tumors once a validated test confirms the fusion.

How Does Larodx (Larotrectinib) Work?

The active ingredient is a highly selective, ATP-competitive inhibitor of the tropomyosin receptor kinase (TRK) family — TRKA, TRKB and TRKC, encoded by the NTRK1, NTRK2 and NTRK3 genes. An NTRK fusion generates an always-on TRK fusion protein that drives tumor growth regardless of location; blocking all three TRK kinases cuts that signal and shrinks tumors across tissues. Larodx uses the sulfate salt formulation in hard gelatin capsules, taken orally twice daily.

Indications of Larodx (Lao Label)

The Lao label mirrors the originator's tissue-agnostic indication: NTRK fusion-positive solid tumors without acquired resistance, locally advanced or metastatic or high-risk-for-surgery, and no satisfactory alternative or progression after prior therapy. The governing rule is patient selection — a validated test must confirm the fusion, because the drug has minimal activity in fusion-negative tumors and in those with acquired TRK resistance mutations such as G595R in TRKA.

Dosage and Administration

The standard dose is 100 mg orally twice daily for adults and children with body surface area of at least 1.0 m², with or without food, until progression or unacceptable toxicity; children below 1.0 m² receive 100 mg/m² twice daily. The 25 mg capsule supports the dose-reduction ladder — 75 mg twice daily as a 25 mg plus 50 mg, and 50 mg twice daily as two 25 mg capsules. Capsules are swallowed whole, and a missed dose within six hours of the next is skipped rather than doubled.

Side Effects of Larodx

Expect the class profile: fatigue, nausea, dizziness, vomiting, cough, constipation, diarrhea and raised AST and ALT in at least 20% of patients. Neurotoxicity — dizziness, cognitive impairment, mood and sleep disturbance — warrants caution with driving and machinery, and hepatotoxicity is managed with liver-function monitoring every two weeks early on and monthly thereafter. Skeletal fractures warrant prompt evaluation, and effective contraception is required during and for one week after treatment because of fetal risk.
