Administration Dosage Frequency Description References
Mice CW2 xenograft model Oral gavage 40 mg/kg Once daily for 14 days To study the effect of combined neratinib and alpelisib on tumor growth in CW2 xenograft models. PMC8355076
Mice STZ-induced type 1 diabetes model and obese Leprdb/db diabetes model intraperitoneal injection 5 mg/kg daily for 35 days (STZ model) or 31 days (db/db model) Neratinib significantly attenuated hyperglycemia and restored β-cell function, survival, and β-cell mass PMC6825211
Mice HER2-positive breast cancer xenograft models Oral 20 mg/kg Once daily, 5 days/week To evaluate the therapeutic benefit of N+T and compare its efficacy to P+T using HER2+breast cancer xenograft models. The results showed that N+T was more effective than P+T in accelerating tumor regression and achieving complete response. PMC8159999
Nude mice Patient-derived xenografts (PDXs) Oral 10 mg/kg Daily for the duration of the experiment To evaluate the effect of Neratinib in combination with other inhibitors on tumor growth in HER2+ PDX models. Results showed that the combination of Neratinib with palbociclib significantly reduced tumor volume and extended event-free survival in all five PDX models. PMC8075007
Female Albino Wistar rats Neratinib-induced diarrhea model Oral 50 mg/kg Once daily for 28 days To investigate the impact of antibiotics on neratinib-induced diarrhea. Results showed that vancomycin or neomycin significantly reduced diarrhea levels, while the broad-spectrum antibiotic cocktail was less effective. PMC9111977
BALB/c Nude mice HCC1954 xenograft model Oral Neratinib 10 mg/kg, Dasatinib 15 mg/kg 5 days on, 2 days off for 10 weeks To evaluate the anti-tumor effect of Neratinib and Dasatinib in vivo on HCC1954 xenograft model, results showed that the combination significantly inhibited tumor growth PMC11396364
NSG mice HER2+ breast cancer model Oral gavage 27 mg/kg Every other day, until tumors reached 1000 mm3 To evaluate the therapeutic effect of Neratinib on HER2+ breast cancer model, results showed that Neratinib significantly inhibited the growth of HME2 parental tumors, but had a smaller effect on the growth of HME2-BM tumors, and overexpression of TG2 diminished the effectiveness of Neratinib.

BALB/C mice HER2-positive breast cancer brain metastasis model Oral gavage 60 mg/kg Once daily for 3 weeks To evaluate the efficacy of Neratinib in a preventive neoadjuvant setting, results showed that Neratinib significantly prolonged survival and reduced the incidence of brain metastases.
