    Abstract: Kaposi's sarcoma (KS) is a multicentric tumor caused by Kaposi's sarcoma–associated herpesvirus. Unmet needs include therapies that are oral, anthracycline sparing, and deliverable in resource-limited settings. We evaluated pomalidomide, an oral immune modulatory agent, in patients with symptomatic KS. Methods The primary objectives were to assess tolerability, pharmacokinetics, and activity. Initial dosage level was 5 mg once per day for 21 days per 28-day cycle, with a de-escalated level of 3 mg if not tolerable, and aspirin 81 mg once per day thromboprophylaxis. HIV-infected patients required controlled viremia with either persistent KS despite 3 months of antiretroviral therapy (ART) or progressive KS despite 2 months of ART. Evaluations included tumor response and health-related quality of life (HRQL). Results Twenty-two patients were treated; 15 (68%) were HIV infected, 17 (77%) had advanced (T1) disease, and 17 (77%) previous KS therapy excluding ART. All were treated with 5 mg because no dose-limiting toxicities occurred. Over 156 cycles, the grade 3/4 adverse events possibly attributable to therapy were neutropenia (23 cycles, 10 patients), infection (1 cycle), and edema (1 cycle). Sixteen patients responded (73%; 95% CI, 50% to 89%): nine of 15 HIV-infected patients (60%; 95% CI, 32% to 84%) and all seven HIV-uninfected patients (100%; 95% CI, 59% to 100%). Median time to response was 4 weeks (range, 4 to 36 weeks). HRQL showed no impairment during therapy and improved satisfaction with appearance at end therapy ( P = .03). Significant increases in CD4 + and CD8 + cells were seen in patients with and without HIV, together with a transient increase in Kaposi's sarcoma–associated herpesvirus viral load at week 4 ( P = .05). Conclusion Pomalidomide is well tolerated and active in KS regardless of HIV status. Responses were rapid, with improved self-reported outcomes, and occurred in advanced and heavily pretreated disease. Correlative studies support, at least in part, an immunologic mechanism of activity.

    A phase I trial of pomalidomide in combination with liposomal doxorubicin in patients with Kaposi sarcoma with or without other KSHV-associated diseases.

    Abstract: 11552 Background: Kaposi sarcoma herpesvirus (KSHV, also known as human herpesvirus 8 [HHV-8]), is the causative agent of Kaposi sarcoma (KS), a multicentric angioproliferative tumor, a form of multicentric Castleman disease (KSHV-MCD), and KSHV inflammatory cytokine syndrome (KICS). KS can be difficult to treat when it occurs with KSHV-MCD or KICS; resulting in high mortality rates. Liposomal doxorubicin (LD) is an FDA-approved treatment for KS. Pomalidomide, an oral immunomodulatory drug, is safe and has demonstrated activity in KS, but the activity of the combination (pomalidomide+LD) in KS alone or with KSHV-associated diseases is unknown. Methods: The primary objective was to evaluate safety and tolerability of pomalidomide+LD in two groups of patients with KS requiring systemic therapy: Group I (GI)- KS alone; Group II (GII)- KS with concurrent KSHV-MCD or KICS. Patients received LD at 20 mg/m 2 intravenously on day 1 of a 28-day cycle combined with pomalidomide once daily on days 1 to 21 at escalating dose levels (DL) (I - 2mg, II - 3mg, or III- 4mg) in a 3+3 design until plateau of response or other pre-specified criteria. Patients received 81mg of aspirin daily as thromboprophylaxis. KS responses were evaluated using the modified AIDS Clinical Trial Group criteria. Results: Thirty-four cisgender men, all with T1-stage KS [21 patients (62%) in GI and 13 patients (38%) in GII] were treated; 32 (94%) were HIV-infected and 22 (65%) had prior chemotherapy for KS (15/21 GI and 7/13 GII). There were no dose-limiting toxicities (DLTs) at DLIII for GI, and additional patients were treated at DLIII. In GII, grade 3 rash and pharyngeal edema were DLTs observed at 3mg of pomalidomide. Overall a median of 6 cycles were administered; the most common grade 3/4 toxicity was neutropenia. Among evaluable patients receiving 〉 2 cycles,17/21 patients in GI had a response (all partial) (81% [95% confidence interval (CI) 58-95%]) and 5/10 patients in GII had a respon se (4 partial and 1 complete) (50% [95% CI 19-81%]). Conclusions: Pomalidomide+LD was well-tolerated and active in heavily pretreated patients with KS alone. In patients with KS and other KSHV-associated diseases, activity was noted but less well-tolerated. Clinical trial information: NCT02659930 .

    Abstract: 10588 Background: Kaposi sarcoma (KS) is a multifocal angioproliferative disorder. VEGFR2-3, PDGFR and c-kit are implicated in KS pathogenesis and inhibited by sorafenib (So). KS is commonly HIV-associated. The antiretroviral drug ritonavir (R) inhibits CYP3A4, and may affect So metabolism and tolerability. Methods: We performed a phase I study of So in KS. HIV+ patients (pts) were eligible if on combination antiretroviral therapy (cART) for 〉 3 months with progressive KS or 〉 4 months with no KS regression. Dose level 1 for pts on R-containing cART (R1) was So 200 mg daily, for pts not receiving R (NR1) So 200 mg every 12 hours. Treatment cycles were 21 days. So pharmacokinetic assessment performed cycle 1 day 8. Adverse event (AE) grade (Gr) by CTCAE v3.0 (2006-10) and v4.0 (2011-12). KS response graded by modified ACTG criteria. Results: 10 pts, R1 (8), NR1 (2). Baseline characteristics: median (med) (range) age 49 (35-72), CD4 in HIV+ 500 cells/uL (35, 747), time on cART 9 months (3.5, 27), previous KS therapies 2 (0-5). 9 HIV-infected, 8/9 HIV viral load 〈 50 copies/mL. 6 had KS-associated edema. Med number cycles 4 (1, 13). Common AE at least possibly attributable to So: anemia, AST/ALT elevation, lipase elevation, hypertension, proteinuria, fatigue, infection, voice alteration. Dose-limiting toxicities (DLT): R1- Gr3 asymptomatic elevated lipase (1), Gr4 thrombocytopenia (1, likely due to multicentric Castleman disease); NR1- Gr3 hand-foot syndrome not resolved by week 6 (1). Other Gr 3-4 AE: R1- hand-foot syndrome (1), Gr3 thrombocytopenia (1), Gr3 transient cerebral ischemia (1), Gr3 hypertension (1); NR1- Gr3 hypertension (2). Best response: partial response (PR) (2), stable disease (SD)(5), progressive disease (1), not evaluable (2). Med duration SD 12 weeks (5, 33). 5/6 with KS-associated edema had objective decrease in edema. R was not associated with clear difference in So C Max or AUC at steady state. Conclusions: Preliminary estimate of PR or better is 20%. Even in some cases where KS did not respond, KS-associated edema improved. However, So was relatively poorly tolerated, with DLT observed at R1 and NR1, and these doses did not yield better responses than established therapies. Additional studies evaluating R’s effect on So metabolites are warranted. Clinical trial information: NCT00287495.
