Studien-Informationen

Brief Summary:

This dose-escalating phase I trial assesses for the first time the safety, the side effects

and the harmlessness, as well as the therapeutical benefit of the new study drug

UniCAR02-T-pPSMA in patients with progressive disease after standard systemic therapy in

castration-resistant prostate cancers with positive PSMA marker. The UniCAR02-T-pPSMA drug is

a combination of a cellular component (UniCAR02-T) with a recombinant antibody derivative

(TMpPSMA) which together forms the active drug.

Ein-/Ausschlusskriterien

Inclusion Criteria:

1. Age ≥ 18 years

2. Patients diagnosed with progressive castration-resistant prostate cancer refractory to

standard treatments and with no other available standard or curative treatment

Tomography (PET)

5. Life expectancy of at least 3 months

6. Adequate renal and hepatic laboratory assessments

7. Adequate cardiac function, i.e. left ventricular ejection fraction (LVEF)

8. Permanent venous access existing (e.g. port-system) resp. acceptance of implantation

of a device

9. Able to give written informed consent

10. Weight ≥ 45kg

11. Using a highly effective method of birth control

Exclusion Criteria:

1. Central nervous system metastasis or meningeosis carcinomatosa

2. Cardiac disease: i.e. heart failure (NYHA III or IV); unstable coronary artery

disease, myocardial infarction or serious cardiac ventricular arrhythmias requiring

anti-arrhythmic therapy within the last 6 months prior to study entry

3. Patients undergoing renal dialysis

4. Pulmonary disease with clinical relevant hypoxia (need for oxygen inhalation)

5. Parkinson, epilepsy and stroke or presence or history of seizures, paresis, aphasia,

central nervous system (CNS) or intracranial hemorrhage

6. History or presence of disseminated intravascular coagulation (DIC) or thromboembolism

within the last three months

7. Multiple sclerosis

8. Hemolytic anemia

9. Eye diseases with neovascularization

10. Active infectious disease considered by investigator to be incompatible with protocol

or being contraindications for lymphodepletion therapy

11. Presence of urotoxicity from previous chemo- or radiotherapy or urinary outflow

obstruction

12. Vaccination with live viruses less than 2 weeks prior lymphodepletion therapy

13. Any disease requiring immunosuppressive therapy

14. Major surgery within 28 days (prior start of TMpPSMA infusion)

15. Other malignancy requiring active therapy but adjuvant endocrine therapy is allowed

16. Treatment with any investigational drug substance or experimental therapy within 4

weeks or 5 half-lives of the substance (whatever is shorter) prior to administration

of TMpPSMA

17. Prior treatment with gene therapy products

18. Use of checkpoint inhibitors within 5 half-lives of the respective substance prior to

administration of TMpPSMA

19. Autoimmune diseases requiring systemic steroids or other systemic immunosuppressants

(note that physiologic steroid replacement not exceeding 10 mg prednisolone equivalent

per day is allowed)

20. Psychologic disorders, drug and/or significant active alcohol abuse

21. Known history of human immunodeficiency virus (HIV) or active/chronic infection with

hepatitis C virus (HCV) or hepatitis B virus (HBV)

diseases (e.g. systemic lupus erythematosus, SS/SLE overlap syndrome, subacute

cutaneous lupus erythematosus, neonatal lupus, primary biliary cirrhosis, Sjögren's

syndrome)

23. Known hypersensitivity to cellular component (UniCAR02-T) and/or targeting peptide

module (TMpPSMA) excipients and/or contraindication to compounds of the

lymphodepletion therapy (cyclophosphamide and fludarabine), and tocilizumab or

corticosteroids as specified in the respective IB/SmPC

24. Evidence suggesting that the patient is not likely to follow the study protocol (e.g.

lacking compliance)

25. Incapability of understanding purpose and possible consequences of the trial

26. Patients who should not be included according to the opinion of the investigator

Studien-Rationale

Primary outcome:

1. Safety and tolerability (Time Frame - DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression)):
Incidence and intensity of adverse events graded according to CTCAE V5.0 with the exception of CRS and ICANS graded according to Lee et al. 2014 and Lee et al. 2019 respectively

2. Incidence of dose limiting toxicity (DLT) (Time Frame - DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression)):
DLT is defined as any adverse event at least possible related to TMpPSMA and/or UniCAR02-T

3. Maximum tolerated dose (MTD) (Time Frame - DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression)):
The dose for which the isotonic estimate of the DLT probability is closest to the target DLT probability of 0.2.

Secondary outcome:

1. Recommended phase 2 dose (RP2D) (Time Frame - DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression)):
The RP2D will be determined based on MTD, all available efficacy data, and all available safety data, including information derived from additional treatment cycles.

2. Antitumor activity (Time Frame - DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression)):
Antitumor activity of UniCAR02-T-pPSMA at any time point according to irRECIST (immune-related) Response Evaluation Criteria in Solid Tumors): Complete remission (CR) and partial remission (PR), Objective response rate (ORR), Disease control rate (DCR), Best response rate, Duration of response (DOR),Progression free survival (PFS)

3. Prostate specific antigen (PSA) response (Time Frame - DLT period (infusion period of TMpPSMA + 7 days or + 14 days in patients with with myelosuppression))

4. Overall Survival (OS) (Time Frame - Until fifteen years after last UniCAR02-T administration)

5. Influence on Circulating tumor cells (CTC) (Time Frame - Before start of lymphodepletion therapy until 6 resp. 12 months after start of last TMpPSMA application)
