Valo Health Suspends Development of DR Drug Candidate After Phase 2 Study Results

Valo Health announced topline data from its phase 2 SPEC­TRA study of OPL-0401 in patients with dia­bet­ic retinopa­thy (DR). The study did not meet its pri­ma­ry or sec­ondary end­points based on the analy­sis in the pre­de­fined pri­ma­ry pop­u­la­tion. Valo decided to sus­pend its devel­op­ment of OPL-0401 and seek a part­ner to fur­ther devel­op the program.

The company noted that cer­tain dos­es test­ed in the study showed poten­tial evi­dence of pre­vent­ing dis­ease pro­gres­sion. Safe­ty and tol­er­a­bil­i­ty were in line with clin­i­cal stud­ies con­duct­ed pri­or to in-licens­ing of OPL-0401, and it was well-tol­er­at­ed.

“There is a sig­nif­i­cant unmet med­ical need for patients suf­fer­ing from dia­bet­ic retinopa­thy, a lead­ing cause of blind­ness in the US, and cur­rent treat­ment options con­sist main­ly of inva­sive intrav­it­re­al injec­tions and laser treat­ment tar­get­ed to patients with more severe or advanced dis­ease,” Bri­an M. Alexan­der, MD, MPH, Chief Exec­u­tive Offi­cer of Valo Health and CEO-Part­ner of Flag­ship Pio­neer­ing, said in a company news release. ​“In light of this crit­i­cal need, we are dis­ap­point­ed that OPL-0401, a poten­tial first-in-class oral option for patients, did not reach its pri­ma­ry or sec­ondary objec­tives. How­ev­er, we are encour­aged by the favor­able safe­ty pro­file and evi­dence of clin­i­cal activ­i­ty with cer­tain dos­es, sug­gest­ing the poten­tial of OPL-0401 to ben­e­fit DR patients. These data col­lec­tive­ly sup­port the fur­ther clin­i­cal eval­u­a­tion of OPL-0401.”

Valo Health's Opal Com­pu­ta­tion­al Plat­form is an AI-dri­ven tar­get and drug devel­op­ment engine designed to accel­er­ate the devel­op­ment of bet­ter med­i­cines for patients. 

“While the data were intrigu­ing, OPL-0401 did not incor­po­rate ele­ments of our plat­form in dis­cov­ery or devel­op­ment. As a result, we are look­ing to find a part­ner well posi­tioned to real­ize the clin­i­cal poten­tial OPL-0401 in DR and beyond. Mov­ing for­ward, Valo’s renewed strate­gic focus will be on oppor­tu­ni­ties that lever­age our Opal plat­form to dis­cov­er new ther­a­peu­tic tar­gets in real world data, val­i­date those tar­gets in human-cen­tric mod­els, and devel­op new med­i­cines with our AI enabled closed loop small mol­e­cule design," Dr. Alexan­der said. ​

SPEC­TRA (NCT05393284) was a mul­ticen­ter ran­dom­ized, dou­ble-blind, place­bo-con­trolled, 24- week study in patients with DR. A total of 114 patients with mod­er­ate­ly severe or severe non-pro­lif­er­a­tive dia­bet­ic retinopa­thy (NPDR) or mild pro­lif­er­a­tive dia­bet­ic retinopa­thy (PDR) were enrolled. The study’s pri­ma­ry objec­tive was to assess the effi­ca­cy of OPL-0401 com­pared to place­bo in improv­ing dia­bet­ic retinopa­thy sever­i­ty score (DRSS). The pri­ma­ry end­point (the por­tion of patients with a 2 or more step improve­ment of DRSS in the study eye as com­pared to place­bo), and the key sec­ondary end­point (the por­tion of patients with a 3 or more step change of DRSS in binoc­u­lar eyes) did not meet sta­tis­ti­cal sig­nif­i­cance. Treat­ment-relat­ed adverse events were infre­quent and mild. There were no treat­ment-relat­ed seri­ous adverse events, and no adverse events relat­ed to liv­er, kid­ney, or heart func­tion were observed. The results from one dose group test­ed in a small num­ber of patients demon­strates a con­sis­tent trend across sev­er­al key effi­ca­cy vari­ables includ­ing the DRSS change and pro­gres­sion to vision threat­en com­pli­ca­tion. This trend needs to be con­firmed in future studies.
