Oysiendx (Osimertinib) 80mg*30 | Laos Generic EGFR TKI | GLT

Generic Information: Oysiendx (Osimertinib) 80mg — Laos

Oysiendx is a Lao-made generic of osimertinib, the third-generation EGFR tyrosine kinase inhibitor originally developed by AstraZeneca under the brand name Tagrisso. Each bottle holds 30 film-coated tablets of 80 mg, the standard once-daily strength used across first-line, maintenance and T790M-positive settings. The product is manufactured by Bigbear Pharmaceutical (Lao) Co., Ltd., a Laos-based manufacturer that produces oncology generics under Lao GMP conditions. Because it carries the same active ingredient and dose as the originator, Oysiendx offers patients an alternative supply route without changing the treatment protocol their oncologist has already established.

The generic name is osimertinib and the brand name is Oysiendx — knowing both matters, because international buyers search under either term. In many Asian markets, generics are labelled only by their INN plus a local brand, so confirming "osimertinib" on the pack is the key identity check.

What Is Oysiendx Used For?

Oysiendx is prescribed for EGFR-mutated non-small cell lung cancer (NSCLC). It is used first-line for advanced disease with EGFR exon 19 deletions or exon 21 L858R mutations, as maintenance after chemoradiation in unresectable stage III disease, as adjuvant therapy after surgery for early-stage disease, and second-line for patients whose tumour has the T790M resistance mutation after a first- or second-generation EGFR TKI. Because osimertinib penetrates the blood-brain barrier well, it is also a meaningful option when brain metastases are present.

How Does Oysiendx Work?

Osimertinib binds irreversibly to mutated EGFR, blocking the kinase signals that drive cancer cell growth. Its defining advantage over earlier EGFR inhibitors is that it also targets the T790M gatekeeper mutation, which is the most common cause of acquired resistance to gefitinib, erlotinib and afatinib. It spares wild-type EGFR at therapeutic doses, which is why rash and diarrhoea tend to be milder than with first-generation agents.

Indications

• First-line metastatic EGFR-mutant NSCLC (exon 19 del / L858R).
• Adjuvant treatment after complete tumour resection in early-stage EGFR-mutant NSCLC.
• Maintenance for unresectable stage III EGFR-mutant NSCLC after chemoradiation.
• T790M-positive NSCLC after progression on a prior EGFR TKI.

Dosage and Administration

The standard dose is 80 mg once daily, with or without food, swallowed whole with water. The tablet should not be crushed or chewed. If a dose is missed by more than 12 hours, it is skipped and the next dose is taken at the usual time. Dose reductions to 40 mg daily may be used to manage toxicity, and treatment continues until disease progression or unacceptable side effects.

Side Effects

Common adverse events include diarrhoea, rash, dry skin, nail changes, stomatitis, fatigue and reduced appetite. More serious but less frequent events include interstitial lung disease (ILD)/pneumonitis, QT interval prolongation and cardiomyopathy. Patients should report new or worsening cough or breathlessness promptly, and routine ECG and cardiac monitoring is advised during treatment.

Storage

Store Oysiendx below 30°C in the original container, away from moisture and direct light, and out of reach of children. Do not use after the printed expiry date.
