Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE1
• Study Classification: INTERVENTIONAL

Brief Summary

Open label phase I study in subjects with glioblastoma at first progression to explore two different administration schedules of lomustine for the combination with L19TNF (ARM 1 and ARM 2).

Patients will be assigned in an alternating fashion to ARM 1 "Fractionating lomustine" or ARM 2 "Priming with L19TNF" as long as both treatment arms are open. Should one treatment arm be stopped as more or equal to two dose limiting toxicities occur in this treatment arm, then all remaining patients will be assigned to the treatment arm that is still open until also this treatment arm will be stopped.

Eligibility Criteria

Inclusion Criteria

1. Male or female, age ≥18.

2. Patients with histologically confirmed glioblastoma per 2021 WHO classification at first progression according to RANO criteria. Imaging data on progression must be available. Resection as previous treatment for progression or recurrence is allowed.

3. MGMT promotor methylation status known or tumor tissue for analysis available.

4. Presence of at least one lesion of measurable disease of 10 x 10 mm in longest perpendicular diameters on baseline MRI according to RANO criteria.

5. Karnofsky performance status (KPS) ≥ 60%.

6. Documented negative test for HIV-HBV-HCV. For HBV serology, the determination of HBsAg and anti-HBcAg Ab is required. In patients with serology documenting previous exposure to HBV, negative serum HBV-DNA is required. For HCV, HCV-RNA or HCV antibody test is required. Subjects with a positive test for HCV antibody but no detection of HCV-RNA indicating no current infection are eligible.

7. Female patients: female patients must be either documented not Women Of Childbearing Potential (WOCBP)* or must have a negative pregnancy test within 14 days of starting treatment. Additionally WOCBP must agree to use, from the screening to 6 months following the last study drug administration, highly effective contraception methods, as defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' Clinical Trial Facilitation Group (www.hma.eu/ctfg.html) and which include, for instance, progesterone-only or combined (estrogen- and progesterone-containing) hormonal contraception associated with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion or vasectomized partner.

Male patients: male subjects able to father children must agree to use two acceptable methods of contraception throughout the study (e.g. condom with spermicidal gel). Double-barrier contraception is required.

8. Personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.

9. Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.

• Women of childbearing potential are defined as females who have experienced menarche, are not postmenopausal (12 months with no menses without an alternative medical cause) and are not permanently sterilized (e.g., tubal occlusion, hysterectomy, bilateral oophorectomy, or bilateral salpingectomy).

Exclusion Criteria

Limited or occasional use of corticosteroids to treat or prevent acute adverse reactions is not considered an exclusion criterion.

25. Presence of active and uncontrolled infections or other severe concurrent disease, which, in the opinion of the investigator, would place the patient at undue risk or interfere with the study.

26. Concurrent malignancies unless the patient has been disease-free without intervention for at least 2 years.
