An Open-Label Randomized Pilot Study of Safety and Preliminary Efficacy of TG100801 in Patients With Choroidal Neovascularization Due to Age-Related Macular Degeneration

Wet age-related macular degeneration (AMD) is caused by the formation and growth of abnormal blood vessels (angiogenesis) in the retina. The new blood vessels have fragile walls and can leak fluid into the retina. The build-up of fluid (edema) under the macula can distort vision or cause vision loss. TG100801 is a topical (eye drop) therapy that has been shown to inhibit ocular angiogenesis, vascular leak, and inflammation in laboratory studies. The primary purpose of this pilot study is to evaluate the ability of topical administration of TG100801 to reduce the amount of fluid in the retina in patients with AMD following 30 days of treatment. An additional objective is to evaluate the safety of TG100801 in patients with AMD.

AbstractAbstract 459Background:A Phase I study of TG101348, a potent, oral JAK2-selective inhibitor in patients with high- or intermediate-risk primary, post-polycythemia vera (PV) and post-essential thrombocythemia (ET) myelofibrosis (MF) recently completed enrollment. Data from the dose escalation cohort (n=28; 30–800 mg administered as a single daily dose) showed dose-linear plasma exposure, with mean elimination T1/2 at steady state ranging from 16 to 34 hours. The dose-limiting toxicity was reversible asymptomatic grade 3 or 4 amylasemia/lipasemia; the maximum tolerated dose was 680 mg. We now present updated results from an extension study in which subjects continued treatment beyond six 28-day cycles.Result:In the entire study, 59 subjects (median age 64 years) were treated. Forty four patients had PMF, 12 post-PV MF, and 3 post-ET MF; 86% were JAK2V617F-positive. Median palpable spleen size was 18 cm and 21 (36%) patients were transfusion-dependent at study enrollment. Forty three (73%) subjects continued treatment on the extension study; the median (range) cumulative exposure to TG101348 was 380 days (170-767); the number of cycles of treatment completed ranged from 7–29, and the proportion of subjects who completed 12, 18, and 24 cycles of treatment was 72%, 28%, and 14%, respectively. The median (range) treatment dose at data cutoff was 440 mg/day (120 to 680 mg/day; n = 35).Toxicity:TG101348 was well tolerated. Non-hematologic, at least possibly related adverse events included nausea (69%; Grade 3=3%), diarrhea (64%; Grade 3=10%), and vomiting (58%; Grade 3=3%), that were dose-dependent; the symptoms were self-limited or controlled with symptomatic treatment and/or dose reduction. Also observed were asymptomatic increases in serum lipase (27%), AST/ALT (27%/25%), creatinine (24%), and alkaline phosphatase (17%). Grade 3/4 hematological adverse events possibly related to TG101348 included treatment-emergent anemia (35% of patients who were not transfusion dependent at baseline), thrombocytopenia (24%), and neutropenia (10%).Spleen:During cycles 1–6, 42% of patients achieved Clinical Improvement (CI) per the International Working Group for Myeloproliferative Neoplasms Research and Treatment (IWG-MRT) criteria for spleen response. The CI rate for the 43 subjects who continued treatment beyond 6 cycles was 65%, and the median time (range) to CI was 140 days (77-802). After 12 cycles, 36 (95%) of the 38 evaluable patients had some degree of spleen size reduction; 32 (85%), 26 (68%), and 10 (26%) of subjects had a minimum 25%, 50%, and 100% decrease in palpable splenomegaly.JAK2V617F allele burden:Of the 48 JAK2V617F mutation-positive subjects, 23 (48%) had a baseline mutant allele burden of >20%. Of these, 20 subjects with a baseline median allele burden (range) of 62% (23% to 100%) completed at least 6 cycles of treatment. Sixteen subjects (80%) exhibited a median 62% (range 6% to 96%) decrease in JAK2V617F burden, including 9 (45%) with a ≥50% decrease; 4 subjects (20%) had increases (range 18% to 58%). Eighteen subjects (78%) completed 12 cycles of treatment; 13 (72%) had a median 50% decrease (range 29% to 82%), including 7 (39%) subjects with a ≥50% decrease; 5 subjects (28%) had no change or increases (range 0% to 22%) in JAK2V617F.Constitutional symptoms:For patients with data at baseline and cycle 6, early satiety, fatigue, night sweats, cough, and pruritus were reported by 56%, 47%, 24%, 22%, and 19% of subjects, respectively. Improvement (complete resolution) rates observed at cycle 6 were: 75% (40%), 65% (29%), 89% (89%), 88% (75%), and 100% (57%) for the aforementioned symptoms, respectively.Leukocytosis/Thrombocytosis:Leukocytosis was present at baseline in 33 subjects; following 6 and 12 cycles of therapy, 57% (n=28) and 56% (n=25) achieved normal WBC counts. Thrombocytosis was noted at baseline for 10 (17%) subjects; following 6 and 12 cycles of therapy, 90% (n=10) and 88% (n=8) achieved normal platelet counts.Conclusion:The current study provides proof-of-concept that selective JAK2 inhibition has anti-myeloproliferative/anti-clonal activity in myelofibrosis. The majority of subjects treated with TG101348 for more than 6 cycles experienced a rapid, significant, and durable decrease in splenomegaly, normalization of leukocyte/platelet counts, and improvement of disease-related symptoms, all within the context significantly decreased JAK2V617F burden.Disclosures:Off Label Use: There is no FDA approved drug for Myelofibrosis.All the drugs discussed will be off-label.

Kinases are known to regulate fundamental processes in cancer including tumor proliferation, metastasis, neovascularization, and chemoresistance. Accordingly, kinase inhibitors have been a major focus of drug development, and several kinase inhibitors are now approved for various cancer indications. Typically, kinase inhibitors are selected via high-throughput screening using catalytic kinase domains at low ATP concentration, and this process often yields ATP mimetics that lack specificity and/or function poorly in cells where ATP levels are high. Molecules targeting the allosteric site in the inactive kinase conformation (type II inhibitors) provide an alternative for developing selective inhibitors that are physiologically active. By applying a rational design approach using a constrained amino-triazole scaffold predicted to stabilize kinases in the inactive state, we generated a series of selective type II inhibitors of PDGFRβ and B-RAF, important targets for pericyte recruitment and endothelial cell survival, respectively. These molecules were designed in silico and screened for antivascular activity in both cell-based models and a Tg(fli1-EGFP) zebrafish embryogenesis model. Dual inhibition of PDGFRβ and B-RAF cellular signaling demonstrated synergistic antiangiogenic activity in both zebrafish and murine models of angiogenesis, and a combination of previously characterized PDGFRβ and RAF inhibitors validated the synergy. Our lead compound was selected as an orally active molecule with favorable pharmacokinetic properties which demonstrated target inhibition in vivo leading to suppression of murine orthotopic tumors in both the kidney and pancreas.

AbstractAbstract 755Background:TG101348 is a potent, orally bioavailable, JAK2-selective small molecule inhibitor, that is currently being evaluated in a Phase I study for the treatment of myelofibrosis. Data from the dose escalation cohort (n=28; 30-800mg administered as a single daily dose) showed dose-linear plasma exposure, with mean elimination T1/2 at steady state ranging from 20 to 52 hours. The dose-limiting toxicity was asymptomatic grade 3 or 4 amylasemia/lipasemia that was reversible, and the maximum tolerated dose (MTD) was 680mg. The most frequent non-hematological toxicities were mild nausea, vomiting, and/or diarrhea that were easily controlled or resolved spontaneously. Grade 3/4 neutropenia and thrombocytopenia were observed in 14% and 25% of patients, respectively. TG101348 had activity in reducing spleen size, leukocyte count, and JAK2V617F (VF) allele burden. Here, we present updated results with a focus on data from the dose confirmation cohort who initiated treatment at a dose of 680mg/day.Results:Fifty nine patients (median age=66 years; range 43-86) have been treated – 28 in the dose escalation phase, and 31 in the dose confirmation phase. Overall, 44 patients had PMF, 12 post-PV MF, and 3 post-ET MF; 86% were VF-positive. Median palpable spleen size was 18cm and 22 patients were RBC transfusion-requiring at study enrollment. After a median follow-up of 12 weeks (range <1-76), 18 (31%) patients have discontinued treatment due to toxicity (n=7; thrombocytopenia=3, neutropenia=1), comorbidities (n=5), withdrawal of consent (n=4), or non-compliance/lack of response (1 each). The remaining 41 patients are currently at the following dose levels: 680mg (n=14), 520-600mg (n=16), 360-440mg (n=10), and 240mg (n=1). The cumulative drug exposure to date is 362 patient-months; exposure at or above MTD (≥680mg) is 154 patient-months. Forty patients (68%) started treatment at ≥680mg.Toxicity:TG101348 is well tolerated. Of the patients who started at ≥680mg, Gr3/4 neutropenia was observed in 15/0% and Gr3/4 thrombocytopenia in 20/10%. Twenty four (60%) patients did not require RBC transfusions at baseline (median Hgb=9.6g/dL; range 7.4-13.1); of these, 42% and 8% of patients developed Gr3 and Gr4 anemia, respectively. The majority of patients who started at ≥680mg developed mild nausea (1 Gr3), vomiting (1 Gr3), and/or diarrhea (3 Gr3) that were self-limited or easily controlled. Other non-hematological toxicities included Gr1/2 transaminitis (38%), Gr1/2 serum creatinine elevation (38%), and asymptomatic hyperlipasemia (33%).Efficacy:Thirty three patients who started at ≥680mg have completed at least 3 cycles of treatment; at 3 months, reduction in palpable spleen size (baseline median=18cms; range 6-32) was at least 50% in 22 (67%) patients; the spleen became non-palpable in 9 (27%) patients. All 21 patients with leukocytosis at baseline (WBC range 11 to 203 ×109/L) who started at ≥680mg have experienced a marked reduction in their WBC count (range 4 to 90); 70% had a normal WBC count at their last follow-up visit. Overall, 48 of the 51 VF-positive patients completed at least 1 cycle and were evaluable for response in VF allele burden; at last available follow-up, the median decrease in granulocyte mutant allele burden was 48%; 21 (44%) patients have had a ≥50% reduction, and in the group who started treatment at ≥680mg, 48% have had a ≥50% reduction. Of those evaluable, there was clinically significant benefit or resolution of constitutional symptoms, including early satiety, fatigue, cough, pruritus, and night sweats.Conclusions:TG101348 continues to be well tolerated in patients with myelofibrosis. Spleen and leukocyte responses are frequent, observed early, and produce substantial clinical benefit for patients. These responses are associated with significant decrease in VF allele burden and point to activity of TG101348 against the malignant clone in myelofibrosis.Disclosures:Pardanani: TargeGen: Research Funding; Cytopia: Research Funding.

Biopharma company Celgene is set to acquire Impact Biomedicines

Celgene has recently announced that it is set to acquire Impact Biomedicines and its drug fedratinib, which will be added to Celgene’s therapies for myelofibrosis (a type of bone marrow cancer) and polycythemia vera. Further payment opportunities will arise upon the drug’s sales performance worldwide. Celgene will pay approximately $1.1 billion upfront and up to $1.25 billion in contingent payments based on regulatory approval milestones for myelofibrosis. The acquisition is one of the largest in the company’s history. "Myelofibrosis is a disease with high unmet medical need as the number of patients who are ineligible for or become resistant to existing therapy continues to increase," commented Nadim Ahmed, President, Haematology and Oncology for Celgene. See also "We believe fedratinib is uniquely positioned as a potential treatment for myelofibrosis and it provides strategic options for us to build leadership in this disease with luspatercept and other pipeline assets." Impact’s Chief Executive, John Hood, is one of the co-inventors of fedratinib when working at TargeGen Inc. Now involved in the sale of fedratinib for the second time, Hood has observed its potential for treating patients with myelofibrosis. “We launched Impact Biomedicines and based on our thorough review of the data, fedratinib presents a compelling risk benefit profile in both treatment-naïve patients and patients who are resistant or intolerant to other JAK2 therapies,” he said. "We believe Celgene is the ideal organisation to follow through on our mission of maximizing fedratinib's potential for patients with myelofibrosis."
