==Dactinomycin monotherapy==
===Regimen variant #1, no cap===
Study 	Dates of enrollment	Evidence 	Comparator 	Comparative Efficacy
Osathanondh et al. 1975 	1965-1973 	Non-randomized (RT) 	 	
Osborne et al. 2011 (GOG 0174)	1999-2007 	Phase 3 (E-switch-ic)	Methotrexate	Seems to have higher CR rate (primary endpoint)
====Chemotherapy====
*Dactinomycin (Cosmegen) 1.25 mg/m2 IV push once on day 1
14-day cycles "until the βhCG assay had reached the institutional normal, or until either a rise or plateau in the βhCG level was observed"
===Regimen variant #2, capped===
Study 	Dates of enrollment	Evidence 	Comparator 	Comparative Efficacy
Schink et al. 2020 (GOG 275)	2012-2016 	Phase 3 (C)	Methotrexate; multi-day	Did not meet primary endpoint of CR rate
Note: to our knowledge, this regimen variant was not tested as an experimental arm in an RCT in this context, prior to becoming a standard comparator arm.
====Chemotherapy====
*Dactinomycin (Cosmegen) 1.25 mg/m2 (maximum dose of 2 mg) IV push once on day 1
14-day cycles until hCG values have returned to normal plus 1 cycle

==Methotrexate monotherapy==
===Regimen variant #1, no escalation===
Study 	Dates of enrollment	Evidence 	Comparator 	Comparative Efficacy
Li et al. 1956 	Not reported 	Pilot 	 	
Li et al. 1958 	1955-1957 	Pilot 	 	
Osborne et al. 2011 (GOG 0174)	1999-2007 	Phase 3 (C)	Dactinomycin	Seems to have lower CR rate
Note: to our knowledge, this regimen was not tested as an experimental arm in an RCT in this context, prior to becoming a standard comparator arm.
====Chemotherapy====
*Methotrexate (MTX) 30 mg/m2 IM once on day 1
7-day cycles "until the βhCG assay had reached the institutional normal, or until either a rise or plateau in the βhCG level was observed"
===Regimen variant #2, with escalation===
Study 	Dates of enrollment	Evidence
Homesley et al. 1988	Not reported 	Phase 2
====Chemotherapy====
*Methotrexate (MTX) as follows:
**Cycles 1 to 3: 30 mg/m2 IM once on day 1
**Cycles 4 to 6: 35 mg/m2 IM once on day 1
**Cycles 7 to 9: 40 mg/m2 IM once on day 1
**Cycles 10 to 12: 45 mg/m2 IM once on day 1
**Cycle 13 onwards: 50 mg/m2 IM once on day 1
7-day cycles for 1 cycle past normalization of β-hCG
====Dose and schedule modifications====
*Methotrexate dose was only escalated if "no major toxicity" was experienced.
