Event Description
A customer from brazil alleged 2 patient samples generated discrepant results for ex20ins when tested with the cobas egfr mutation test v2, when compared to retest results.The alleged samples generated a mutation detected result for l858r and ex20ins in the initial tests with tissue samples.Retests generated only a mutation detected result for l858r for both samples.For both patients, initial results were reported out (l858r and ex20ins).No harm was alleged.An investigation is ongoing.
 
Manufacturer Narrative
Roche received complaints from customers reporting the generation of false mutation detected results for the exon 20 insertion (ex20ins) mutation when using the cobas® egfr mutation test v2.During in-house testing using customer-provided ffpet samples, an ex20ins false mutation detected result was reproduced for one out of 8 ffpet samples, which was processed following the validated sample preparation method from the instructions for use.Although the majority of cases reported were from users using ffpet samples, the generation of false mutation detected ex20ins results with plasma specimens was reported in one case.A false mutation detected ex20ins result could lead to harm under specific scenarios.Consignees will be notified of the issue with instruction to follow the instructions for use for sample input requirements.Additionally, if an ex20ins mutation detected result is generated with the cobas® egfr mutation test v2, customers must confirm the result with another method (e.G., sequencing or other pcr-based tests).Correction to device code from non-reproducible results to false positive result.(b)(4).
