New pill RAP-103 aims to clear psoriasis in 8 weeks

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Signed written informed consent a. Patients must be willing to participate in the study and sign the informed consent form 2. Type of patient and target disease characteristics 1. Men and women, diagnosed with stable plaque psoriasis for 6 months or more. Stable psoriasis is defined as no morphology changes or significant flares of disease activity, in the opinion of the investigator 2. Deemed by the investigator to be a candidate for systemic therapy 3. ≥10% of body surface area (BSA) involvement at screening visit and Day 1 4. Psoriasis Area and Severity Index (PASI) score ≥12, and static Physician's Global Assessment (sPGA) ≥3 at screening visit and Day 1 3. Age and reproductive status 1. Men and women aged 18 years to 70 years at the time of screening visit 2. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test at screening visit, and a negative urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin within 24 hours prior to the start of study drug 3. Women must not be pregnant, lactating, breastfeeding, or planning pregnancy during the study period 4. Women of childbearing potential must agree to correctly use a highly effective method(s) of contraception for the duration of treatment plus 30 days (duration of ovulatory cycle) for a total of 33 days post-treatment completion (total of 33 days after last dose of study drug). WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements, but must still undergo pregnancy testing as described in this protocol 5. Male patients who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study treatment(s) plus 5 half-lives of the study treatment (3 days) for a total of 3 days post-treatment completion. Additionally, male patients must be willing to refrain from sperm donation during this time 6. Investigators shall counsel WOCBP, and male patients who are sexually active with WOCBP, on the importance of pregnancy prevention and the implications of an unexpected pregnancy. Investigators shall advise on the use of highly effective methods of contraception, which have a failure rate of \<1% when used consistently and correctly. Exclusion Criteria: 1. Use of phototherapy 4 weeks or less prior randomization 2. Infectious/immune-related exclusions 1. History or evidence of outpatient active infection and/or febrile illness within 7 days prior to Day 1 2. History of serious bacterial, fungal, or viral infection requiring hospitalization and intravenous antimicrobial treatment within 60 days prior to Day 1 3. Any untreated bacterial infection within 60 days prior to Day 1 4. Any ongoing evidence of chronic bacterial infection (eg, chronic pyelonephritis, chronic osteomyelitis, chronic bronchiectasis) 5. Any history of proven infection of a joint prosthesis in which the prosthesis was not removed or replaced, or received antibiotics for suspected infection of a joint prosthesis in which the prosthesis was not removed or replaced 6. Received live vaccines within 60 days prior to Day 1, or plans to receive a live vaccine during the study, or within 60 days after completing study treatment 7. Presence of herpes zoster lesions at screening or Day 1 8. History of serious herpes zoster or serious herpes simplex infection, which includes, but is not limited to, any episode of disseminated herpes simplex, multidermatomal herpes zoster, herpes encephalitis, ophthalmic herpes, or recurrent herpes zoster (recurrent is defined as 2 episodes within 2 years) 9. Evidence of, or positive test for, hepatitis B virus at screening. Positive hepatitis B lab testing is defined as 1) positive hepatitis B surface antigen (HBsAg+) OR 2) presence of hepatitis B virus DNA OR 3) positive anti-hepatitis B core antibody without concurrent positive hepatitis B surface antibody (HBcAb+ and HBsAb-) 10. Evidence of, or positive test for, hepatitis C virus (HCV) at screening. A positive test for HCV is defined as: positive for hepatitis C antibody (anti-HCV Ab) AND 2) positive via a confirmatory test for HCV (for example, HCV polymerase chain reaction) 11. Positive for human immunodeficiency virus by antibody testing (HIV-1 and -2 Ab) at screening 12. Any history of known or suspected congenital or acquired immunodeficiency state or condition that would compromise the patient's immune status (eg, history of opportunistic infections \[eg, Pneumocystis jirovecii pneumonia, histoplasmosis, or coccidioidomycosis\], history of splenectomy, primary immunodeficiency) 3. Any of the following tuberculosis (TB) criteria: 1. History of active TB prior to screening visit, regardless of completion of adequate treatment 2. Signs or symptoms of active TB (eg, fever, cough, night sweats, and weight loss) during screening, as judged by the investigator 3. Any imaging of the chest (eg, chest x-ray, chest computed tomography scan) obtained during the screening period, or any time within 6 months prior to screening with documentation, showing evidence of current active or history of active pulmonary TB 4. Latent TB infection (LTBI) defined as positive interferon gamma release assay (IGRA), by QuantiFERON-TB Gold testing at screening, in the absence of clinical manifestations Note: Patient is eligible if (i) there are no current signs or symptoms of active TB AND (ii) patient has received adequate documented treatment for LTBI within 5 years of screening OR has initiated prophylactic treatment for LTBI per local guidelines and is rescreened after 1 month of treatment. To continue in the study, patient must agree to complete a locally recommended course of treatment for LTBI. Use of rifampin, however, is not recommended as it can reduce efficacy of apremilast used as a comparator in this trial Note: An IGRA test that is indeterminate must be retested for confirmation. If the second test is again indeterminate, the patient will be excluded from the study. If the retest is positive, the patient should be treated as having LTBI. If the retest is negative, the patient may be eligible provided no other exclusion criteria for TB are met. 4. Medical history and concurrent diseases 1. Any major surgery within 8 weeks prior to Day 1, or any planned surgery for the first 52 weeks of the study 2. Has donated blood \>500 mL within 4 weeks prior to Day 1, or plans to donate blood during the course of the study 3.

Any major illness/condition or evidence of an unstable clinical condition (eg, renal, hepatic, hematologic, gastrointestinal, endocrine, pulmonary, psychiatric, neurologic, immunologic, or local active infection/infectious illness) that, in the investigator's judgment or after consultation with the medical monitor, will substantially increase the risk to the patient if he or she participates in the study 6.

If an initial BP reading exceeds this limit, the BP may be repeated once after the patient has rested sitting for ≥10 minutes. If the repeat value is less than the criterion limits, the second value may be accepted. 8. Class III or IV congestive heart failure by New York Heart Association Criteria 9. Has cancer or history of cancer (solid organ or hematologic including myelodysplastic syndrome) or lymphoproliferative disease within the previous 5 years (other than resected cutaneous basal cell or squamous cell carcinoma, or carcinoma of cervix in situ that has been treated with no evidence of recurrence) 10. Any uncontrolled psychiatric illness (such as untreated depression, or bipolar disorder) judged as clinically significant by the investigator during screening or at Day 1 OR any lifetime history of suicidal ideation, suicidal behavior, or suicidal attempts by medical history or by electronic Columbia-Suicide Severity Rating Scale (eC-SSRS) documentation, or by answering "yes" to Question 4 or 5 for suicidal ideation on the eC-SSRS at screening or at Day 1, or is clinically deemed to have a suicide risk by the investigator 11.
