Description of intervention(s) / exposure
Treatment: Other - 4-L-[131I]iodo-phenylalanine (131I-IPA)
Experimental: Single administration of 131I-IPA (1f group) - 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.
Experimental: Three administrations of 131I-IPA (3f-parallel group) - Study participants will be administered in 2GBq in 3 fractions corresponding to ? 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.
Experimental: Three administrations of 131I-IPA (3f-sequential group) - Study participants will be administered in 2GBq in 3 fractions corresponding to ? 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.
Experimental: Dose escalation of fractionated dosing - 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.
Treatment: Other: 4-L-[131I]iodo-phenylalanine (131I-IPA)
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
