Temozolomide and lomustine

University Hospital, Bonn · Phase 3 active Small molecule Under review Quality 0/100

Temozolomide and lomustine is a Alkylating agent (nitrosourea combination) Small molecule drug developed by University Hospital, Bonn. It is currently in Phase 3 development for Glioblastoma multiforme, Recurrent or progressive high-grade glioma. Also known as: Temodal, Temomedac, CeCeNu.

Temozolomide and lomustine are alkylating agents that cross the blood-brain barrier and cause DNA damage to kill cancer cells, particularly effective in brain tumors.

Temozolomide and lomustine (also known as semustine) are small molecule DNA inhibitors used to treat various types of brain and central nervous system tumors, including glioblastoma, astrocytoma, and melanoma. They are classified as inhibitors and have been studied in clinical trials for their efficacy and safety in treating these conditions.

Likelihood of approval
61.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr

Mechanism of action

Both drugs are nitrosoureas/alkylating agents that methylate DNA at the O6-guanine position, leading to DNA strand breaks and apoptosis. Temozolomide is a prodrug converted to its active form MTIC, while lomustine acts directly. The combination targets rapidly dividing cells and is particularly suited for CNS penetration in glioblastoma and other brain malignancies.
