The patient presented on February 18, 2020, with a platelet count of 18109/L, which was a reduction compared with her previous visit (166109/L, January 14, 2020). Proliferation of haematopoietic and megakaryocytic progenitor cells was also greater with the combination than with avatrombopag or rhTPO alone, indicating an additive effect early in the maturation process. If we bring these agents into the first-line setting, can we improve responses or decrease the rate of relapses that are very high in patients getting steroids [upfront]? It has also been reported that a TPO-RA combined with a low steroid dose (2.55 mg prednisolone) can benefit patients who were not responding to treatment [23]. The proportion of patients achieving the target platelet count (50109/L) on procedure day was significantly higher in avatrombopag versus placebo recipients in both the low and high baseline platelet count cohorts in both studies (p<0.0001 for all comparisons).

[3] Complete platelet response (platelet count 100109/L) was achieved at 24.1% of visits in patients initially randomized to avatrombopag and 18.3% of visits in patients switched from placebo to avatrombopag. After a stable platelet count has been achieved, platelet counts should be obtained at least monthly. Thrombopoietin binds to only the distal domain, activating the receptor and initiating several signal transduction pathways, notably JAK/STAT, but also MAPK and various anti-apoptotic pathways [9]. Man Y, Lu Z, Yao X, Gong Y, Yang T, Wang Y. 8600 Rockville Pike One trial found a greatly improved survival when no LOH was present (96% vs. 54%), but a subsequent trial did not confirm this, therefore further study is required. Atorvastatin: Uses, Interactions, Mechanism of Action - DrugBank The patient ultimately was taken off fostamatinib and it was demonstrated that avatrombopag 40 mg/day monotherapy was quite effective in achieving and maintaining high platelet values. Preclinical activity of eltrombopag (SB-497115), an oral, nonpeptide thrombopoietin receptor agonist. In the placebo-controlled study, patients with chronic (12 months in duration) ITP and low platelet count at baseline (average of two platelet counts <30109/L) were randomized to 6 months treatment with placebo (n=17) or avatrombopag.

Limited data are available describing outcomes in patients who switched from romiplostim or eltrombopag to avatrombopag, a newer oral TPO-RA. Avatrom bopag significantly increased the chance of achieving durable platelet response and reducing the use of concomitant ITP medication vs placebo, and significantly reduced the incidence of any bleeding events compared with placebo, eltrombopag, and romiplostim. Avatrombopag/eltrombopag/romiplostim | SpringerLink Rituximab and fostamatinib are less effective than splenectomy and fostamatinib has mainly been evaluated in patients who have received two or more previous therapies. Minimization of the use of corticosteroids because of tolerability concerns is a key aspect of management guidelines for ITP, with corticosteroid use suggested only when platelet counts drop below 30109/L in patients who are asymptomatic or have minor bleeding, and then only in short (<6 weeks total) courses [2]. The reported overall rates and severity of adverse events appear to be generally similar to that seen with other TPO-RAs with no new or unique adverse events occurred in avatrombopag recipients that had not been previously observed in patients treated with eltrombopag [30] or romiplostim [31]. Eltrombopag: (Moderate) Eltrombopag is metabolized by CYP1A2. Thirty-two ITP patients were randomized to avatrombopag and 17 were randomized to placebo during a 26-week core study period (with 21 study visits), followed by an open-label extension period, in which all patients received avatrombopag for varying lengths of time.
