Aiming to transform treatment of liver and biliary tract cancers with immunotherapy combinations at ASCO GI
A late-breaking presentation will feature results from the HIMALAYA Phase III trial showing a statistically significant and clinically meaningful overall survival (OS) benefit with a single priming dose of tremelimumab added to IMFINZI® (durvalumab) in 1st-line unresectable liver cancer.
This trial used a novel dose and schedule called the STRIDE (Single Tremelimumab Regular Interval Durvalumab) regimen. HIMALAYA is the first Phase III trial to show that a dual immunotherapy regimen has improved OS in this setting.
A second late-breaking presentation will highlight results from the TOPAZ-1 Phase III trial for IMFINZI plus chemotherapy in advanced biliary tract cancer, which was unblinded early at an interim analysis in
The combination demonstrated a statistically significant and clinically meaningful OS benefit versus chemotherapy alone in 1st-line advanced biliary tract cancer, making it the first immunotherapy combination to demonstrate superior clinical outcomes over standard of care in a global, randomized trial in this setting.
Also at the meeting, the first data from IMFINZI plus bevacizumab in the Study 22 Phase II trial will provide the efficacy and safety profile of this combination in unresectable liver cancer. This regimen is being tested in the EMERALD-1 Phase III trial of transarterial chemoembolization in combination with IMFINZI alone and with bevacizumab in patients with locoregional liver cancer, as well as in the EMERALD-2 Phase III trial with liver cancer patients who are at high risk of recurrence after curative hepatic resection or ablation.
Challenging the status quo in prostate cancer with an industry-leading PARP inhibitor at ASCO GU
A late-breaking presentation will showcase the results from the PROpel Phase III trial of LYNPARZA® (olaparib) plus abiraterone, which showed the combination significantly delayed disease progression in 1st-line metastatic castration-resistant prostate cancer (mCRPC) regardless of biomarker status. LYNPARZA is the first PARP inhibitor to demonstrate clinical benefit in combination with a new hormonal agent in this setting.
Additionally, an oral presentation will feature the results of the BAYOU Phase II trial evaluating the combination of LYNPARZA and IMFINZI in unresectable, Stage IV bladder cancer. Data will show comparable efficacy of IMFINZI monotherapy to that of other immune checkpoint monotherapy data in similar trial populations and will suggest additional research into a potential role for PARP inhibition in subsets of patients with specific gene mutations.
Harnessing the potential of antibody drug conjugates across HER2-targetable cancers
At ASCO GI, data will include an encore presentation of the OS results of the DESTINY-Gastric01 Phase II trial of ENHERTU® (fam-trastuzumab deruxtecan-nxki) in HER2-positive metastatic gastric and gastro-esophageal junction adenocarcinoma (GEJA), and initial results from the DESTINY-Gastric03 Phase Ib/II trial in HER2-positive gastric cancer and GEJA.
In
Additional ENHERTU data at ASCO GI will include encore results from the DESTINY-CRC01 Phase II trial showing clinically meaningful activity in HER2-positive unresectable and/or metastatic colorectal cancer. The overall safety and tolerability profile of ENHERTU in DESTINY-CRC01 was consistent with that seen in previously reported ENHERTU trials. There are currently no medicines approved to specifically treat HER2-positive colorectal cancer.
At ASCO GU, results will be shared from the primary analysis of a Phase Ib trial of ENHERTU in combination with nivolumab in HER2-expressing bladder cancer.
Collaboration in the scientific community is critical to improving outcomes for patients.

Warnings and Precautions
Interstitial Lung Disease / Pneumonitis
Severe, life-threatening, or fatal interstitial lung disease (ILD), including pneumonitis, can occur in patients treated with ENHERTU. Advise patients to immediately report cough, dyspnea, fever, and/or any new or worsening respiratory symptoms. Monitor patients for signs and symptoms of ILD. Promptly investigate evidence of ILD. Evaluate patients with suspected ILD by radiographic imaging. Consider consultation with a pulmonologist. For asymptomatic ILD/pneumonitis (Grade 1), interrupt ENHERTU until resolved to Grade 0, then if resolved in ≤28 days from date of onset, maintain dose. If resolved in >28 days from date of onset, reduce dose one level. Consider corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥0.5 mg/kg/day prednisolone or equivalent). For symptomatic ILD/pneumonitis (Grade 2 or greater), permanently discontinue ENHERTU. Promptly initiate systemic corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥1 mg/kg/day prednisolone or equivalent) and continue for at least 14 days followed by gradual taper for at least 4 weeks.
Metastatic Breast Cancer
In clinical studies, of the 234 patients with unresectable or metastatic HER2-positive breast cancer treated with ENHERTU 5.4 mg/kg, ILD occurred in
Locally Advanced or Metastatic Gastric Cancer
In DESTINY-Gastric01, of the 125 patients with locally advanced or metastatic HER2‑positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, ILD occurred in
Neutropenia
Severe neutropenia, including febrile neutropenia, can occur in patients treated with ENHERTU. Monitor complete blood counts prior to initiation of ENHERTU and prior to each dose, and as clinically indicated. For Grade 3 neutropenia (Absolute Neutrophil Count [ANC] <1.0 to 0.5 x 109/L) interrupt ENHERTU until resolved to Grade 2 or less, then maintain dose. For Grade 4 neutropenia (ANC <0.5 x 109/L) interrupt ENHERTU until resolved to Grade 2 or less. Reduce dose by one level. For febrile neutropenia (ANC <1.0 x 109/L and temperature >38.3ºC or a sustained temperature of ≥38ºC for more than 1 hour), interrupt ENHERTU until resolved. Reduce dose by one level.
Metastatic Breast Cancer
In clinical studies, of the 234 patients with unresectable or metastatic HER2-positive breast cancer who received ENHERTU 5.4 mg/kg, a decrease in neutrophil count was reported in
Locally Advanced or Metastatic Gastric Cancer

Use in Specific Populations
- Pregnancy: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. There are clinical considerations if ENHERTU is used in pregnant women, or if a patient becomes pregnant within 7 months following the last dose of ENHERTU.
- Lactation: There are no data regarding the presence of ENHERTU in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with ENHERTU and for 7 months after the last dose.
- Females and Males of Reproductive Potential: Pregnancy testing: Verify pregnancy status of females of reproductive potential prior to initiation of ENHERTU. Contraception: Females: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with ENHERTU and for at least 7 months following the last dose. Males: Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ENHERTU and for at least 4 months following the last dose. Infertility: ENHERTU may impair male reproductive function and fertility.
- Pediatric Use: Safety and effectiveness of ENHERTU have not been established in pediatric patients.
-
Geriatric Use: Of the 234 patients with HER2-positive breast cancer treated with ENHERTU 5.4 mg/kg,
26% were ≥65 years and5% were ≥75 years. No overall differences in efficacy were observed between patients ≥65 years of age compared to younger patients. There was a higher incidence of Grade 3-4 adverse reactions observed in patients aged ≥65 years (53% ) as compared to younger patients (42% ). Of the 125 patients with locally advanced or metastatic HER2‑positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg in DESTINY-Gastric01,56% were ≥65 years and14% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. - Hepatic Impairment: In patients with moderate hepatic impairment, due to potentially increased exposure, closely monitor for increased toxicities related to the topoisomerase inhibitor.
