Eligibility Criteria:
Inclusion Criteria:~* Be willing and able to comply with study visits and procedures;~* Have signed written informed consent prior to participating in this extension study;~* Have completed either antecedent study AG348-C-006 or AG348-C-007 through the Part 2 Week 24 Visit;~* Cohorts 2 and 3: Have demonstrated clinical benefit from AG-348 treatment in the antecedent study, in the opinion of the Investigator;~* For women of reproductive potential, have a negative pregnancy test during screening;~* For women of reproductive potential as well as men with partners who are women of reproductive potential, be abstinent as part of their usual lifestyle, or agree to use 2 forms of contraception, 1 of which must be considered highly effective, from the time of giving informed consent, during the study, and for 28 days following the last dose of study drug for women and 90 days following the last dose of study drug for men.~Exclusion Criteria:~* Have a significant medical condition (including clinically significant laboratory abnormality) that developed during his/her antecedent AG- 348 study that confers an unacceptable risk to participating in this extension study, that could confound the interpretation of the study data, and/or that compromises the ability of the participant to complete study visits and procedures.~* Are currently pregnant or breastfeeding.~* Have a splenectomy scheduled during the study treatment period.~* Meet the withdrawal criteria of his/her antecedent AG-348 study during screening of this extension study.~* Are currently receiving medications that are strong inhibitors of cytochrome P450 (CYP)3A4 that have not been stopped for a duration of at least 5 days or a time frame equivalent to 5 half-lives (whichever is longer) before start of study drug; or strong inducers of CYP3A4 that have not been stopped for a duration of at least 28 days or a time frame equivalent to 5 half-lives (whichever is longer) before start of study drug on this extension study.~* Have received anabolic steroids, including testosterone preparations, within 28 days prior to start of study drug on this extension study.~* Have received hematopoietic stimulating agents (eg, erythropoietins, granulocyte colony stimulating factors, thrombopoietins) within 28 days prior to start of study drug on this extension study.~* Have exposure to any investigational drug other than AG-348, device, or procedure within 3 months prior to start of study drug on this extension study.

Study Arms:
- Cohort 1 (Type: EXPERIMENTAL): Participants who received placebo in Study AG348-C-006 will enroll in Cohort 1.~Part 1 (Dose Optimization Period, 12 weeks): Participants will begin by receiving 5 milligrams (mg) orally, twice a day. Each participant's dose of AG-348 may be increased to 20 mg twice a day and then to 50 mg twice a day depending on their response to AG-348 and tolerability.~Part 2 (Fixed Dose Period, 12 weeks): Last dose received in Part 1, twice a day.~After completion of Part 2, participants who, in the opinion of the Investigator, have demonstrated clinical benefit from AG-348 treatment will continue AG-348 treatment in the Continued Treatment Period.
- Cohort 2 (Type: EXPERIMENTAL): Participants who received AG-348 in Study AG348-C-006 will enroll in Cohort 2.~Participants will continue the AG-348 dose regimen they were receiving at the last visit of Study AG348-C-006.
- Cohort 3 (Type: EXPERIMENTAL): Participants who received AG-348 in Study AG348-C-007 will enroll in Cohort 3.~Participants will continue the AG-348 dose regimen they were receiving at the last visit of Study AG348-C-007.
