TALZENNA Safety and Therapy Management

Adverse Events

Manageable safety and tolerability with TALZENNA vs chemotherapy1,2
Adverse Events* (in ≥20% of Patients Receiving TALZENNA) in EMBRACA2,3

Adapted from Litton et al. Suppl Appendix 2018.2

*Graded according to NCI CTCAE 5.
Includes anemia, hematocrit decreased, and hemoglobin decreased.
Includes neutropenia and neutrophil count decreased.
§Includes thrombocytopenia and platelet count decreased.
||For talazoparib, Grade 1 is 21% and Grade 2 is 2%. For chemotherapy, Grade 1 is 20% and Grade 2 is 8%. Grade 1 defined as hair loss of <50% of normal for that individual that is not obvious from a distance but only on close inspection; a different hair style may be required to cover the hair loss, but it does not require a wig or hair piece to camouflage. Grade 2 defined as hair loss of ≥50% of normal for that individual that is readily apparent to others; a wig or hair piece is necessary if the patient desires to completely camouflage the hair loss; associated with psychosocial impact. 
Includes fatigue and asthenia.




Manageable safety profile vs chemotherapy4


Special Warnings and Precautions for TALZENNA1


#Graded according to NCI CTCAE 5.




Most adverse events in the EMBRACA study were managed with standard supportive medical therapy or dose interruption/reduction4,5


The median time to first dose reduction due to an adverse event was 19.3 weeks with TALZENNA vs 9.3 weeks with oral chemotherapy6**

  • Dose interruptions due to an adverse event of any grade occurred in 60% of patients receiving TALZENNA and 33% of those receiving oral chemotherapy
  • Dose reductions due to any cause occurred in 52% of TALZENNA patients and 49% of patients on oral chemotherapy


**Capecitabine was the only oral chemotherapy included in the comparator arm.




Therapy Management

Dose modifications due to adverse events

  • Adverse events resulting in dose modification (reduction or interruption) occurred in 66% of patients on TALZENNA vs 60% of patients on chemotherapy4

Incidence of Dose Modifications Due to Adverse Events With TALZENNA in EMBRACA2


††Percentages were calculated based on total number of patients in the safety population with a hematologic adverse event who were treated with TALZENNA during the month interval.

Detecting and managing anemia5,6


Incidence of Grade ≥3 Anemia Over Time6 



Detecting and managing neutropenia5,6


‡‡In post hoc exploratory analysis. The analysis data cutoff date was September 15, 2017, and was conducted in the safety population.
§§Anemia includes preferred terms: anemia, decreased hemoglobin, decreased hematocrit.
|| ||Neutropenia includes preferred terms: neutropenia, decreased neutrophil count.
