CARD Trial

Comments

 Well designed addressing an unmet clinical need

 Patient population representative

 Toxicit did not seem worse (choose 20 mg/mq?)

 Always consider G-CSF

 Unanswered questions

 Extrapolation in castration sensitive?

 Patients with PS=2 or worse

 Patients responding to prior ART > 12 months

 The PEACE-1 is a positive trial

 It will certainly carry costs and toxicities

 It will also beg the question at what point is clinical benefit,

overshadowed by costs, praticality and toxicity

Refusal of a change to the marketing authorisations for Opdivo (nivolumab) and Yervoy (ipilimumab)

On 26 July 2018, the Committee for Medicinal Products for Human Use (CHMP) adopted a negative opinion, recommending the refusal of a change to the marketing authorisations for the medicinal products Opdivo and Yervoy. The change concerned adding the use of both medicines in combination for the treatment of renal cell carcinoma (kidney cancer).

The company that applied for the change to the authorisation is Bristol-Myers Squibb Pharma EEIG. It may request a re-examination of the opinion within 15 days of receipt of notification of this negative opinion.

W h a t a r e Op div o a n d Ye r v oy ?

Opdivo and Yervoy are cancer medicines. They contain the active substances nivolumab and ipilimumab respectively.

Opdivo has been authorised since June 2015. It is already used on its own to treat renal cell carcinoma in patients who have previously been treated with other cancer medicines. It is also used to treat the following other cancers: melanoma (a type of skin cancer), non-small cell lung cancer, classical Hodgkin lymphoma (a blood cancer), squamous cell cancer of the head and neck, and urothelial (bladder) cancer.

Yervoy has been authorised since July 2011. It is used to treat adults with advanced melanoma.

Further information on Opdivo and Yervoy’s current uses can be found on the Agency’s website.

W h a t w e r e Op div o a n d Ye r voy e x pe ct e d t o be u se d f or ?

Opdivo and Yervoy were also expected to be used together in patients with previously untreated advanced renal cell carcinoma that was considered to be of moderate or high risk of worsening.

TITAN trial Trial

A truly practice changing study?

 Boosting improved ORR in first line (from 28,7% to 37%)

 Boosting improved ORR in second line (from 18,2% to 28,3%)

 Ipilimumab boost can rescue 10% of patients

(26)

Combination trials

(27)

CTLA-4 and PD-1 blockade

Rationale for combinations

(28)

Anti–CTLA-4 plus anti–PD-1 utilizes cellular mechanisms distinct from monotherapies

Wei SC, PNAS 2019

 Highly phenotypically exhausted cluster of

differentiation 8 (CD8) T cells expand in frequency following anti–PD-1 monotherapy but not combination

 Activated terminally differentiated effector CD8 T cells expand only following combination therapy.

 Combination therapy also led to further increased

frequency of T helper type 1 (Th1)-like CD4 effector T

cells even though anti–PD-1 monotherapyis not

sufficient to do so.

(29)

TITAN trial Trial

A truly practice changing study?

 CR rates with this strategy is lower than with other combination

 Not all candidates could finally receive the boost (77% in first line)

 PFS and OS are still immature

 Is this the right moment for monotherapy?

Conclusions

(49)

“Although the goal of such investigations—to increase the number of patients who may benefit from this type of therapy—is laudable, the sometimes empiric manner of how agents are brought together is leading to an unrealistic number of trials and expected volunteers, making it unlikely that all hypotheses will be robustly answered”.
