There was no significant difference between early vs. late HTRT, though there was a trend toward higher response rate for late HTRT. Early HTRT is given during cycle 1 of chemotherapy; late HTRT is given during cycle 4 of chemotherapy.

Blackhall et al. 2021 (TAHOE)	2017-2018	Phase 3 (C)	Rovalpituzumab tesirine	Superior OS
Edelman et al. 2022 (DISTINCT)	2017-NR in abstract	Phase 3 (C)	1. Irinotecan & Dinutuximab	Did not meet primary endpoint of OS
			2. Irinotecan	Not reported

Chemotherapy

• Topotecan (Hycamtin) 1.5 mg/m² IV over 30 minutes once per day on days 1 to 5

Supportive therapy

• (varies depending on reference):
• G-CSF use per physician discretion
• In von Pawel et al. 2014 (ACT-1), "Prophylactic antibiotics were recommended for patients at high risk of infectious complications."

21-day cycles Duration varies depending on reference:

• In von Pawel et al. 1999 treatment is given until progression of disease, unacceptable toxicity, or 6 cycles beyond maximal response. Patients with stable disease after 4 cycles could have treatment discontinued at physician discretion.
• In Eckardt et al. 2007, patients with complete or partial response continued treatment progression of disease or 2 cycles beyond best response. Patients with stable disease received at least 4 cycles therapy.
• In ACT-1, treatment was given for 6 cycles or until progression of disease. Patients who had at least stable disease by cycle 6 could receive another 6 cycles of treatment.

Regimen variant #3, oral route

Study	Years of enrollment	Evidence	Comparator	Comparative Efficacy
Eckardt et al. 2007	1999-2001	Phase 3 (E-switch-ic)	Topotecan; IV (1.5 mg/m2)	Did not meet primary endpoint of ORR
O'Brien et al. 2006 (GSK 104864/478)	2000-2004	Phase 3 (E-esc)	Best supportive care	Seems to have superior OS
Baize et al. 2020 (GFPC 01-2013)	2013-2018	Phase 3 (C)	Carboplatin & Etoposide	Inferior PFS
Spigel et al. 2021 (CheckMate 331)	2015-2017	Phase 3 (C)	Nivolumab	Might have inferior OS

Note: Duration of treatment details vary depending on reference. In GSK 104864/478, treatment is given for at least 4 cycles, though this depended on tolerability and response. In Eckardt et al. 2007, patients with complete or partial response continued treatment progression of disease or 2 cycles beyond best response. Patients with stable disease received at least 4 cycles of therapy. Patients enrolled in GFPC 01-2013 received 6 cycles.

Chemotherapy

• Topotecan (Hycamtin) 2.3 mg/m² PO once per day on days 1 to 5

21-day cycle for 4 or more cycles (see note)
