| Single administration of 131I-IPA (1f group) | EXPERIMENTAL | Study participants with GBM receive a single administration of 4-L-\[131I\]iodo-phenylalanine (131I-IPA), followed by 18 cycles of external radiotherapy, each cycle being of 2 Gy. |
| Three administrations of 131I-IPA (3f-parallel group) | EXPERIMENTAL | Study participants will be administered in 2GBq in 3 fractions corresponding to ⅓ full dose activity (0.67 GBq for the 2.0 GBq dose level). The 1st fraction of 131I-IPA will be administered as above, 1- 3 days prior to 1st XRT. The 2nd and 3rd 131I-IPA fractions will be administered after 5-9 XRT fractions (subject to investigator's discretion and day of IMP administration) following the previous 131I-IPA fraction. The remainder of XRT fractions will be given following the 3rd 131I-IPA fraction. |
| Three administrations of 131I-IPA (3f-sequential group) | EXPERIMENTAL | Study participants will be administered in 2GBq in 3 fractions corresponding to ⅓ full dose activity (0.67 GBq for the 2.0 GBq dose level). The 1st fraction of 131I-IPA will be administered as above 1- 3 days prior to 1st XRT. The 2nd 131I-IPA fraction will be administered after all 18 XRT fractions have been completed, and the 3rd 131I-IPA fraction will be administered 1 week after the 2nd 131I-IPA fraction. |
| Dose escalation of fractionated dosing | EXPERIMENTAL | Dose escalation will be made in steps of 2.0 GBq, i.e. 4.0 (3\*1.33 GBq), 6.0 GBq (3\*2.0 GBq), up to 8.0 GBq (3\*2.67 GBq) until the maximum tolerated dose (MTD) is reached, using cohorts of N=3 patients. |

| 4-L-[131I]iodo-phenylalanine (131I-IPA) | RADIATION | Study participants will receive by intravenous infusion an escalating activity of 4-L-\[131I\]iodo-phenylalanine (131I-IPA). Additional therapy is received in the form of externally administered radiotherapy |
Inclusion Criteria: 1. Previously confirmed histological diagnosis of GBM, with current clinical or imaging evidence for first recurrence according to modified RANO criteria (2017). History of GBM standard therapy (debulking surgery, followed by radio-chemotherapy (50-60 Gy in 2 Gy fractions, temoz...
4-L-iodo-phenylalanine is an investigational drug being studied for the treatment of Glioblastoma Multiforme (GBM), a type of brain cancer. It is currently in Phase 1 clinical development, meaning it is still being tested in early-stage trials to evaluate its safety and potential efficacy in patients.
4-L-iodo-phenylalanine is being developed by Telix Pharmaceuticals Limited, a biopharmaceutical company. Telix Pharmaceuticals is publicly traded under the ticker symbol TLX. The company is conducting clinical research on this drug for the treatment of Glioblastoma Multiforme.
4-L-iodo-phenylalanine is in Phase 1 clinical development. It is an investigational drug, meaning it has not yet been approved by regulatory authorities. The drug is being studied for the treatment of Glioblastoma Multiforme, and its Phase 1 trial has been completed.
4-L-iodo-phenylalanine has one completed clinical trial registered under NCT03849105, titled "131I-IPA and Concurrent XRT in Recurrent GBM." This Phase 1 study enrolled 10 patients with Glioblastoma Multiforme and was conducted in Australia, Austria, and the Netherlands.
Yes, 4-L-iodo-phenylalanine is also known as 131I-IPA, as indicated by the clinical trial title. The drug is being studied in combination with concurrent external beam radiation therapy (XRT) for the treatment of recurrent Glioblastoma Multiforme.
