Bile tube cancer is again targeted for new drugs: Ivosidenib and Binimetinib are highly effective

Author . . Leaf maple red liver bile tube cancer is a highly heterogeneous, invasive cancer, its prognosis is poor, the five-year survival rate is less than 10%, for can not be removed or metastatic bile tube cancer, Gissithamin combined cisplatin chemotherapy has been the standard treatment.
Since the first bile tube cancer target drug pemigatinib was officially launched to end the era of bile gallbladder tumor only chemotherapy, the targeted drug let liver and bile tumor patients see hope again, bile tracheal tumor target drug research firepower.
to introduce you today to two new drugs, Ivosidenib and Binimetinib.
Ivosidenib is a powerful oral targeted inhibitor for IDH1 mutations, and recently, The Lancet magazine again revealed Ivosidenib's significant efficacy in the clllDHy clinical trial of bile tube cancer.
The ClareDHy trial was a multi-center, randomized, double-blind, placebo-controlled multi-center lll clinical study.
a total of 185 patients with bile tube cancer who received 1-2 systemic treatments but developed the disease and carried mutations in the IDH1 gene were randomly divided into Ivosidenib (124) and placebo groups (61) by a 2:1 ratio.
500 mg Ivosidenib daily in patients with bile tube cancer in the Ivosidenib group, and oral placebo daily in patients with bile tube cancer in the placebo treatment group.
results were 1, the medium PFS (no progression lifetime) Ivosidenib group: placebo group: 2.7 months: 1.4 months (HR s 0.37, 95% CI: 0.25-0.54, p.lt;0.001).
reduced the risk of death by 63%, which is a good number for patients with bile tube cancer who have received treatment above the first line.
2, Medium OS (Total Lifetime) Ivosidenib Group: Placebo Group : 10.8 months: 9.7 months (HR s 0.69, 95% CI: 0.44-1.10, p s 0.06).
data from the Ivosidenib group were not significantly different from those in the placebo group because 35 patients in the 61 placebo group had oral Ivosidenib treatment in the latter stages of the group.
If patients with bile tube cancer in the placebo group had been taking oral placebos, a model analysis showed that the middle OS in the placebo group was only 6 months (HR.46, 95% CI: 0.28-0.75, p.lt;0.001).
3, DCR (disease control rate) Ivosidenib group: placebo group : 53% : 28%.
Ivosidenib was significantly superior to the placebo group.
4, ORR (objective mitigation rate) Ivosidenib group: placebo group : 2% : 0%.
Ivosidenib stabilizes patients with bile tube cancer by inhibiting tumor cell proliferation, preventing tumor progression.
2 percent may seem low, but Ivosidenib's disease control rate is as high as 53 percent.
5, the medium duration of Ivosidenib group: placebo group : 2.6 months (IQR 1.4-6.0): 1.6 months (1.1-2.7).
6. In terms of safety, adverse events (TEAEs) common during treatment in the Ivosidenib group included nausea (32.1%), diarrhea (28.8%), fatigue (23.7%), Cough (19.2%), abdominal pain (18.6%), abdominal water (18.6%), decreased appetite (17.3%), anemia (16.0%), vomiting (16.0%).
46 percent in the Ivosidenib group, 36 percent in the placebo group, and no treatment-related deaths.
Binimetinib Binimetinib is a powerful, highly selective MEK1/2 variant inhibitor, and the MEK protein is an upstream regulatory factor pathway for extracellular signal-related kinases (ERKs).
preclinical studies have shown synergy between biethylin and chemotherapy (chemotherapy).
The clinical trial, an open, one-arm phase IB study designed to evaluate patients with first-line gistatic tube cancer in the second- and third-line treatment of bile tube cancer with a methinib joint Capedabin treatment, was designed as an indigested dose and a queue extension.
The study included 34 patients, of whom 9 were in the dose increment group and 25 were in the queue expansion group, of which 25 patients (73.5%) were treated first-line and 9 patients (26.5%) were treated with second-line treatment.
also had 29.4% gallbladder cancer (n s 10), 29.4% (n s 10), 26.5% (n s 9) and 14.7% (n s 5) for hepatoblast cancer.
results: 1, ORR: 20.6% (95% CI, 7.0-34.2).
2, DCR: 76.5% (95% CI, 62.2-90.8).
7 patients (20.6%) and 19 patients (55.9%) showed partial remission and disease stabilization, respectively.
3, mPFS: 4.1 months (95%CI, 2.8-5.7), 3 months PFS rate of 64.0%, 4, mOS: 7.8 months (95% CI, 5.9-12.2) in the logo In terms of materials, patients with abnormal activation of the RAS/RAF/MEK/ERK signal path showed longer PFS (April vs 2.6, P=0.031) and OS (10.8 vs 5.3, P=0.011).
major adverse reactions are controllable anemia and fatigue.
the treatment showed effective therapeutic efficacy in bile tube cancer, especially in patients with abnormally activated bile tube cancer with RAS/RAF/MEK/ERK signaling pathlines.
bile tube cancer is a high degree of malignant cancer in China, the prognosm is relatively poor and the treatment means are limited.
is that there has been more and more research on targeted drugs in recent years, and we look forward to new treatment models that will change the future and rewrite the guidelines.
