Abstract
TPS595 Background: Neoadjuvant chemotherapy (NACT) is a well-established treatment modality in MIBC but suffers from limited activity and significant toxicity. Recently, neoadjuvant immunotherapy (I/O) has demonstrated clinical safety and efficacy in various solid tumor indications including MIBC, with potentially less toxicity. Results from previous studies of single-agent I/O indicated a proportion of pathologic complete responses (ypT0N0) similar to that reported with NACT. Therefore, improving ypT0N0 responses remains a major task for successful treatment of MIBC in the future. Increasing evidence has emerged that Growth and Differentiation Factor 15 (GDF-15) plays a critical local immunosuppressive. Apart from blocking immune-cell entry into tissues GDF-15 also has major impact on the formation of the immune synapse. Many tumors overexpress GDF-15 and have hijacked this mechanism to block I/O therapy success. Various translational research efforts have indicated that GDF-15 may play a significant role for immunosuppression and T-cell exclusion in urothelial carcinoma (UC). Visugromab (CTL-002) is a GDF-15 neutralizing IgG4 monoclonal antibody that has demonstrated in Phase 1 a favorable safety profile and promising clinical activity with durable and deep responses in PD-1/PD-L1 relapsed/refractory metastatic solid tumors in combination with the anti-PD1 antibody Nivolumab (Nivo)*. This clinical trial is intended to investigate the combination of Visugromab with Nivo vs. Nivo monotherapy as neoadjuvant therapy for MIBC in patients (pts) who are ineligible for or elect not to undergo NACT. Primary endpoints are the complete pathologic response rate and radiologic response. Methods: This is a multi-center, parallel-cohorts and single-blinded Phase 2 study of neoadjuvant therapy in pts planned for radical cystectomy (RC). A total number of 30 subjects with stage T2-T4N0M0 MIBC will be enrolled and assigned 1:1 to receive either Nivo + Visugromab or Nivo + Placebo after stratification for CPS PD-L1 expression and cT-stage. No statistical assumptions have been undertaken at this stage. Treatment consists of three 4-week cycles [i.v., Q4Wk], and RC is planned 4-8 weeks after last dose of study drug. After RC, pts will follow standard recommendations according to EAU guidelines. Primary endpoints are the proportion of ypT0N0 response and radiologic response rate. Secondary endpoints comprise additional efficacy parameter, surgical and medical safety, PK and PD assessments. Translational research includes evaluation of immunologic parameters in the tumor, other immune-correlates and molecular profiles, as well as evaluation of treatment-emergent cytokine and chemokine profiles in peripheral blood. * Melero et al., Annals of Oncology (2022) 33 (suppl_7): S331-S355.

Abstract
Abstract
Background: Growth and differentiation factor 15 (GDF-15) is a TGF-β superfamily member physiologically expressed mainly in placenta and linked to feto-maternal tolerance. Under pathophysiologic conditions, prevention of excessive immune cell infiltration during tissue damage and cachexia induction have been ascribed to GDF-15. A recent study [Haake et al. AACR2020; Abstract #5597] elucidated a mechanism by which GDF-15 inhibits LFA-1 activation on CD8+ T cells, thus interfering with effector T cell recruitment to tissues. Importantly, several cancer entities secrete high levels of GDF-15, correlating with poor prognosis and reduced overall survival [reviewed in Front Immunol 2020 May 19;11:951]. To block this effect the GDF-15 neutralizing antibody CTL-002 was generated. In preclinical models CTL-002 demonstrated potent effector T cell shifting into tumor tissue by neutralizing GDF-15 and enhancing response to checkpoint inhibitor therapy. Methods: This is a phase 1, first-in-human (FIH), two-part, open-label clinical trial of intravenous (IV) administration of CTL-002 given as monotherapy and in combination with an anti-PD-1 antibody in subjects with advanced-stage, relapsed/refractory solid tumors who relapsed on or were refractory to a prior anti-PD-1/PD-L1 therapy. Eligible subjects have exhausted all available approved standard treatments, including prior anti-PD1/-PD-L1 treatment, and present with a biopsy-accessible tumor for serial biopsy taking. The trial is termed GDFATHER, for “GDF-15 Antibody-mediaTed Effector cell Relocation”. Main endpoints are safety of CTL-002 monotherapy and CTL-002 combination with an anti-PD-1 antibody, pharmacokinetics, pharmacodynamics (e.g., degree of GDF-15 neutralization achieved and change in immune-cell number and composition in the tumor tissue) as well as preliminary clinical efficacy (tumor mass reduction; anticachexia effect). In part A of the trial (dose escalation) up to 24 subjects will receive escalating doses of CTL-002 IV (0.3 – 20 mg/kg) in a „mono-followed-by-combination“-design with CTL-002 given as monotherapy and followed by combination with an anti-PD-1 checkpoint inhibitor. In part B (expansion) up to 5 cohorts with up to 25 subjects per cohort with defined tumor entities expected to be GDF-15 dependent will be treated to determine the recommended phase 2 dose (RP2D) and further evaluate safety and preliminary efficacy of CTL-002 monotherapy and the combination. The study was initiated in December 2020 and enrolled the first patient on Dec 09, 2020. Cohort 4 is ongoing at time of submission (07/2021) and so far no DLT has occurred. Updated safety, biomarker and response assessments will be reported. The ClinicalTrials.gov Identifier is NCT04725474.

Abstract
Purpose To evaluate the safety and tolerability of intravitreal ISTH0036, an antisense oligonucleotide selectively targeting transforming growth factor beta 2 (TGF-β2), in patients with primary open angle glaucoma (POAG) undergoing trabeculectomy (TE; glaucoma filtration surgery). Methods In this prospective phase I trial glaucoma patients scheduled for TE with mitomycin C (MMC) received a single intravitreal injection of ISTH0036 at the end of surgery in escalating total doses of 6.75 μg, 22.5 μg, 67.5 μg or 225 μg, resulting in calculated intraocular ISTH0036 concentrations in the vitreous humor of approximately 0.3 μM, 1 μM, 3 μM or 10 μM after injection, respectively. Outcomes assessed included: type and frequency of adverse events (AEs), intraocular pressure (IOP), numbers of interventions post trabeculectomy, bleb survival, visual acuity, visual field, electroretinogram (ERG), slit lamp biomicroscopy and optic disc assessment. Results In total, 12 patients were treated in the 4 dose groups. Main ocular AEs observed were corneal erosion, corneal epithelium defect, or too high or too low IOP, among others. No AE was reported to be related to ISTH0036. All other safety-related analyses did not reveal any toxicities of concern, either. The mean medicated preoperative IOP at decision time-point for surgery was 27.3 mmHg +/- 12.6 mmHg (SD). Mean IOP (±SD) for dose levels 1, 2, 3, and 4 were at Day 43 9.8 mmHg ± 1.0 mmHg, 11.3 mmHg ± 6.7 mmHg, 5.5 mmHg ± 3.0 mmHg and 7.5 mmHg ± 2.3 mmHg SD; and at Day 85 9.7 mmHg ± 3.3 mmHg, 14.2 mmHg ± 6.5 mmHg, 5.8 mmHg ± 1.8 mmHg and 7.8 mmHg ± 0.6 mmHg, respectively. In contrast to IOP values for dose levels 1 and 2, IOP values for dose levels 3 and 4 persistently remained below 10 mmHg throughout the observation period. Conclusion This first-in-human trial demonstrates that intravitreal injection of ISTH0036 at the end of TE is safe. Regarding IOP control, single-dose ISTH0036 administration of 67.5 μg or 225 μg at the time of TE resulted in IOP values persistently < 10 mmHg over the three month postoperative observation period.

Abstract
The temporal and spatial transcription patterns of the Xenopus laevis Bone morphogenetic protein 2 (BMP-2) gene have been investigated. Unlike the closely related BMP-4 gene, the BMP-2 gene is strongly transcribed during oogenesis. Besides some enrichment within the animal half, maternal BMP-2 transcripts are ubiquitously distributed in the early cleavage stage embryos but rapidly decline during gastrulation. Zygotic transcription of this gene starts during early neurulation and transcripts are subsequently localized to neural crest cells, olfactory placodes, pineal body and heart anlage. Microinjection of BMP-2 RNA into the two dorsal blastomeres of 4-cell stage embryos leads to ventralization of developing embryos. This coincides with a decrease of transcripts from dorsal marker genes (beta-tubulin, alpha-actin) but not from ventral marker genes (alpha-globin). BMP-2 overexpression inhibits transcription of the early response gene XFD-1, a fork head/HNF-3 related transcription factor expressed in the dorsal lip, but stimulates transcription of the posterior/ventral marker gene Xhox3, a member of the helix-turn-helix family. Activin A incubated animal caps from BMP-2 RNA injected embryos show transcription of ventral but an inhibition of dorsal marker genes; thus, BMP-2 overrides the dorsalizing activity of activin A. The results demonstrate that BMP-2 overexpression exerts very similar effects as have previously been described for BMP-4, and they suggest that BMP-2 may act already as a maternal factor in ventral mesoderm formation.
