Agios Pharmaceuticals, Inc. (NASDAQ: AGIO)

Technical Analysis
Short-Term Resistance: ~$66
Short-Term Support: ~$56

Agios Pharmaceuticals, Inc. is a company I see potential value in. From a technical analysis standpoint, it appears a reversal was confirmed in 2019 and has trended positively. It appears to have met a resistance around $66 and currently found a support near $56. If the support is confirmed, Agios may continue following their positive trend. I have not taken a position; however, this company is currently on my watch list. This company currently has two approved products, TIBSOVO® (ivosidenib) and IDHIFA® (enasidenib), and three other products in clinical development.  

TIBSOVO® (ivosidenib) is an isocitrate dehydrogenase-1 (IDH1) inhibitor indicated for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with a susceptible IDH1 mutation as detected by an FDA-approved test4. Isocitrate dehydrogenase mutations result in accumulation of oncometabolite 2-hydroxyglutarate, which causes epigenetic changes and impaired cellular differentiation.3  Agios is seeking a new indication for TIBSOVO® for the treatment of patients with newly diagnosed acute myeloid leukemia with an IDH1 mutation not eligible for standard therapy with a Prescription Drug User Fee Act (PDUFA) date of 21 June 2019.

Efficacy Results

The supplemental new drug application (sNDA) submission for the indication of treatment of patients with newly diagnosed AML with IDH1 mutation not eligible for standard therapy is based on results from phase 1, single-arm, open-label, multicenter, dose escalation and expansion study of ivosidenib (NCT02074839). This study is currently active but is not recruiting subjects. The study describes the preliminary analysis of ivosidenib effect on remission and transfusion independence in patients with IDH1-mutant untreated AML.

The primary efficacy endpoint is complete response (CR) + CR with partial hematologic recovery (CRh). Additional endpoints include objective response rate (ORR), CR, duration of response, time to response. The response definitions are modified criteria from the International Working Group recommendations from 2013. The response definitions are summarized in Table 1.2 As of 11 May 2018, all patients with enrolled with untreated AML received ivosidenib starting dose of 500 mg once daily (n=34) (Table 2). Efficacy results are summarized in Table 3.3

CONCLUSION:

Ivosidenib induced a durable response with a CR+CRh rate of 42%, lower bound of a 95% confidence interval of 6.5 months, and an objective response rate of 58%. The median duration for both the primary objective and the ORR were not estimable due to the study being ongoing.
